General construction.

transverse dial shaft 3, which is journaled in bearings on the main frame, the dials being so arranged that the dial represent ing the lowest number is arranged on the right hand end of the series and the dials representing the successively higher numbers being arranged successively in their order toward the left from the dial representing the lowest number. The lowest or right hand dial is preferably divided on its periphery into eighths so as to indicate fractions of a cent in eighths, and the remaining dials are graduated on their periphery according to the decimal system into tenths. As shown in the drawings ten total dials are shown and extend from fractions of a cent to tens of millions, but if desired, additional dials may he added to the right and to the left of the series, if it is desired to register smaller divisions of a cent or more than tens of millions. Each of the main total dials 2 is provided on its left hand side with a gear pinion &, which is rigidly connected therewith, as shown in Fig. 2. The pinion of the fraction wheel has eight teeth while the pinions of the remaining dials are each provided with ten teeth. 5 represents the main registering gear segments, one of which is pro.-.led for each of the dials 2 and is adapted to engage with the pinion thereof, for operating the respective dial. Each of these g ar segments is arranged in rear of its companion gear pinion and is provided at its lover end with a rearwardly projecting arm 6 which is pivoted loosely on a transverse supporting rod 7. This rod is mounted with its ends on the upper ends of two rock arms 8 which turn loosely with their lower ends on a ransverse rock-shaft f). The rock-arms S are connected by a transverse bar 10 which compels the two arms to move back and forth together. In the normal position of the gear segments when the machine is at rest these segments are retracted rearwardly out of engagement with the dial pinions of the dials and the segments are elevated so that their lowermost teeth are opposite the spaces between the adjacent teeth of the dial pinions, these paces being in line with the pivots of the pinions and the gear segments.

The gear segments are yieldingly hcld baclzwardly out of engagement wi h the dial pinions by means of springs 11 connecting the rock-arms 8 with a stationary part of the frame. Fig. 7 shows one of the springs 11 connectin one of the rock-arms 8 with transverse stationary bar 12 in the rear part of the machine. The gear segments are moved forwardly so that their teeth engage with the dial pinions 4 by means of a shifting root-arm 13, which is preferably secured to the right hand rockarm 8 and projects rearwardly. Upon raising theshifting rock-arm 13, the rockarms 8 are swung forwardly and the gear segments 5 are engaged with the dial pinions, while upon swinging the shifting rock-arms downwardly. the rock-arms 8 are swung rearwardly and the gear segments are disengaged from the dial pinions.

on rear end of the shifting arm 13, as shown in Figs. 2, and 11. Upon swinging frame 15, so that the cam 1i wardly, the incline of the latter "ages underneath the roller 18 and aises ie arm 15. thereby moving the arms 8 for- 19 has been raised to the top of the in\, .ne, the concentric portion of the cam engages with the roller during the con inued forward movement of the cam and the la t r does not shift the gear segments any farther forward.

ll hen the rear end f the concentric face 1'? of the cam passes forwardly from under 1 the roller 18, the constant pull of the sprin s 11 causes the rock-arm 13 to be ded and the rock-arms 8 to be moved rward, thcrehy disengaging the gear segments from the dial pinions. Upon now moving the cam l-il; backwardly together with the rocking frame 1:, this cam does not affect the arm 13 and the parts connected therewith, but is affected by said arm at too last portion or the backward movement of the cam, at which time the ack or lower side of incline 16 engages with the roller 19 which lifts said incline. and at the end of the backward movementof the cam. the latter clears sai d roller and drops behind the same. as shown in Fig. preparatory to again raising the roller 18 and connecting parts during the next forward ovemcnt of the cam 1 1.

w r the purpose permitting the front end of the cam to rise so as to clear the roller 18, this cam is p'i 'oted at its rear end to the rear portion of the rocking frame 1.5. The upward and downward movement of the front end of the cam is limited by means of a lug l9 projecting from the side. of the cam and engaging with a slot in the adjacent. part of the rocking frame 15, as shown in Fig. 11.

The rocking frame 15 is secured with its lower portion to a transverse rock-shaft 2O jonrnaled in the main frame and provided outside of the frame with a hand crank 21, as shown in Fig. 11, whereby this shaft is rocked and the parts connected therewith are operated.

The g r egm nts 5 are raised to their highest position by means of a return or lifting-bar' 22 which extends transversely underneath all of the arms 6 of the gear se ments and which is connected loosely at i s rear ends with the transverse rod 7 by lifting plates 23. 24 represents two siifting arms which are mounted loosely at their rear ends on the rock-shaft 20 and which support at their'other ends transverse bar 25 which transverse bar is connected at its ends by two links 26, with the lifting plates 23, whereby upon raising the shifting arms 24, the lifting bar 22 is caused to raise the gear segments and the other parts connected pendent of the transverse bar therewith resting on said her. Upon depressing the transverse bar 25, the lifting}; bar 22 is moved downwardly and the gear segments resting thereon are permitted to move downwardly with the bar until the segments are arrested.

Each of the gear segments is yieldingly held in contact with the lifting bar 22 by a spring'27 which connects the arm of the seg ments with the transverse bar 25. the downward movement of the gear segment is arrested while the shifting arms 2econtinue to move downwardly, the lifting lar 22 is moved away from the underside of the arm of the gear segment and the spring is strained. The transverse bar 2-5 is arranged at one end in a segmental notch 28 formed in the front part of the rocking frame 15, shown in Figs/9. and 11 and its opposite end is arranged in a similar segmental notch 528, formed in a' rocking frame 29 which is se cured to the operating shaft 20 on the lefthand side of the machine. The rocking frames 15 and 29, together with the operatingshaft 2O constitute the main or universal operating frame of the machine.

lVhen'the' machine is at rest, as shown in Fig. 2, the transverse'bar 25 with the front side of the notches 28 in the rocking frames 15 and 29. Upon turnii the rocking shaft 20 forwar lly by means of its handle 21' in the direction of the arrow 2, the rocking frames are moved forwardly during the first art of the movement indo- The la ttcr remains at rest until the inclined front end 16 of the cam 14: has raised the a m 13 and moved the gear segments into e gagement with the dial pinions, during which movement the rocking frames move idly the extent of their notches 28 along; the ends of the bar 26 without disturbing the latter. After the gear segments have been engaged with the dial pinions, the continued forward movement of the rocking frames causes the rear ends of their notches 28 to engage with the bar 2-5 and depress the same, thereby causing the lifting bar 22 to he moved downwardly and strain the springs 27. This causes all of the gear segments which are free, to be moved downwardly and to continue their downward movement until they are arrested. During the downward movement of the gear segments, while they are engagement with the dial pinions, the latter and the dials connected therewith are turned in the direction of the arrow, 7, until the downward movement of the segments is arrested. The extent which each is turned depends upon the position in which the downward movement of its operating segment is arrested. fter the seg ments have been arrested in their downward movement they remain in this position while the rocking fra .ies complete their forward movement. At the end of the forward movement of the rocking frames, the roller 18 of the reel: arm 13 drops off from the rear end of the concentric part of the cam lei, thereby allowing the springs ll. to pull the gear segments rearwardly out of engagement from the dial pinions.

Upon now turning the roclcshaft 2O haclo wardly by means of the handle 21., the rock ing frames are moved baclrwardly until the front ends of the notches engage with bar 25. When the latter is so engaged it is moved backwardly with the rocking frames to the end of their rearward movement which causes the transverse bar 9.5 to lift the l ing bar 22 and the gear segments which have been depressed into their highest or normal position. During upward movement of the cepresscil gear segments they are out of engagement with the dial pinions whereby the dials are not turned haclr'ivardly with the segments but remain in their shifted position.

30 represents number of elbow-shaped controlling rms, which form part of the devices so that the downward movement of the registe ar segments is controlled. One or i is arranged along the lefthand s.de of each gear segment and consists of upright front part and a horizontal lower part which enteinls rearwardly from the lower end of the upright part, thereby leaving a clear space in rear of the upright part of the controlling lever as represented in F l, 2 and 14-. The rear end of the lower part of each controlling arm is mountcd loosely on a transverse supporting her 3'1, while the upper end of s front or upright part is loosely counoctml with the upper portion of its companion g r segment. This loose connection permits the controlling arm and the gea segment to swing freely about their iud'. lnal a s which are arranged parallel but out or e, and also permits the gear segment to move'forward and backward into and out of engagement with its corn nion dial pinion. In the uppermost positmn of the controlling arms the same bear with their upper ends against a transrerse stop bar as shown in Fig. 2, which limits the upward movement of these arms.

Each controlling arm is provided on the rear part of its upper end with a locking lug 33, and on the frpnt part of its upper end with a stop lug 3%, both of which lugs project toward the left and are preferably stamped out of one piece with the controlling arm.

The operation of the registering devices is controlled by a number of elbow-shaped key levers which are arranged side by side and pivoted to a transverse supporting rod Each key lever is provided with a lower actuating arm 36 which projects forwardly and an upper stop arm 37 which projects upwardly along the left hand side of one of the controlling arms and gear segments, as

represented in F 2. Each of these keylevers is provided on the rear side of its stop arm with a locking shoulder 38 which is adapted to engage with the locking lug 83 of the controlling arm when the latter is elevated into its highest position and the key-lever is in its fully retracted position, as shown in Fig. 2. When the parts are in this position, the key lever holds the controlling arm against downward movement and the latter holds the gear segment against downward movement. If the gear segment while so held against downward movement is moved forward into engagement with the adjacent dial pinion and the rocking frames are turned forwardly for depressing the gear segment, the spring 27 of this segment will be strained without however, shifting the segment. At the end of this forward movement of the rocking segments, the roller 18 of the rock arm 13 drops off from the rear end of the cam 14, the gear segment is moved rearwardly out of engagement from the dial pinion and then the rocking frames move backwardly without having shifted the dial.

The upper arm of each key lever is provided on its front side with a vertical series of differential stop shoulders 39, which are arranged step fashion and extend from the upper end of this arm downwardly and forwardly thereon or in other words the stop shoulders 39 are arranged radially out of line with one another and different dis tances from the pivot of the key lever. These stop shoulders of the key lever are adapted to be moved forwardly into the path of the stop lug 34 on the controlling arm. The stop shoulders are arranged different distances from the stop lug 34C of the controlling arm, so that by moving different stop shoulders of the key lever into the path of the stop lug of the controller arm, the latter and the gear segment connected therewith may be arrested at different points in their downward movement. The uppermost stop shoulder of the key lever is most remote from the stop lug of the controlling arm and therefore requires the greatest forward movement of the key lever, in order to bring this stop shoulder into the path of this stop lug.

The stop shoulders of the key lever are so arranged that the distance from the stop shoulders to the path of the stop lug gradually grows less from the uppermost stop shoulder to the lowermost stop shoulder. The relative position of the different stop shoulders of the key lever is such that when its locking shoulder 38 remains in engagement with he locking lug 33 and the gear segment is simply moved into and out of engagement with its dial pinion, the latter remains at zero, if the same has not been previously moved. But when the key lever has been moved forwardly, so as to disengage its locking shoulder from the locking lug and moves one of its stop shoulders into the path of the stop lug of the controlling arm, the latter arm and gear segment connected therewith will be moved downwardly upon moving the rocking frames forwardly, until the stop lug of the controlling arm strikes the respective stop shoulder of the key lever which stands in its path, whereby the gear segment while turning in engagement with the adjacent dial gear pinion turns the same forward. By turning the key lever forward more or less and moving one or the other of its stop shoulders into the path of the stop lug 34': of the control ling arm, the distance which this arm descends can be varied, thereby varying the number of spaces which its gear segment turns the adjacent dial.

d1 (tin number key wwclzam'sm.

T0 represents the main keys whereby the key levers of the main registering and recording mechanism are operated, and which are guided with their depending stems in the top 41 and bottom 42 of the key-board. As shown in the drawings, nine longitudinal columns of these keys are arranged transversely side by side. The first column on the right hand side of the machine contains seven keys and represents fractions of one-eighth of a cent, the next column toward the left contains nine keys and represents cents and the remaining columns of keys toward the left each contains nine keys and represents progressively higher orders of numbers according to the decimal system, so that the registering keys in the last or left hand column represent hundreds of thousands of dollars.

The lowest numbers of the several columns of keys are arranged transversely in a row on the rear part of the keyboard and the corresponding higher numbers of the several columns are arranged likewise in transverse rows and progressively in their order toward the front end of the keyboard.

the key board.

The downward movement 01 all of the keys is substantially the same, but the arrangement of each column of toys lengthwise of the lower actuating arm of each key lever causesthe keys to bear against the lever at different distances from its pivot so that by depressing different keys the same distance, the key lever will be turned d tferent-distances. The keys having the lowest numbers bear against their respective "key levers'nearest the pivot and consequently the levers are thereby thrown the greatest distance, and the uppermost stop shoulders are shifted in to the path oi? the stop lug 3st of the respective controlling arms. The throw of each key lef-er upon de pressing any one of its keys is so adjusted,

- 'that the proper stop shoulder on its upper arm is moved into the path of the stop lug 3 1- of the controlling arm and the downward movement of the respective gear segmentis arrested after having turned the adjacent dial gear pinion a number of spaces corresponding to the number of the key which is depressed.

Z0086 dormant-i002 for segments.

. The loose connection between each conthe upper end oi the segment and bearing against the upper and lower guide faces l and 48, which are formed on the upper end of its companion controlling arm. As the controlling a an and segment rise and fall, the guide lugs ofthe segment slide back and forth on the guide faces of the arm. The guide faces are so constructed that the back and forth movement of the segment on the arm radially with reference to the dial pinion in all positions of the segment. By so forming the guide faces oi the arm, the gear segment can be engaged with and disengaged from the dial pinion in all positions of the. segment without disturbing theposition ot the dial pinion. The construction .of the loose connections between the controlling arms and gear segments of all of the higher registering devices above the fractional registering device are combined with carrying devices, whereby each registering dial, upon making one complete turn, causes the next higher dial to be turned forward one space, thereby carrying up a number from one column to the next higher column. T he loose connections between the controlling arms and the segments and the carrying mechanism of the higher registering devices are constructed as follows As shown in Figs. land 2, each controlling arm is provided at its upper end with upper and lower guide faces a and l8 and its lower guide face is engaged by a lower guide lug 46 on the adjacent gear segment the same, as in the coupling between the controlling arm and segment of the initial registering device. Tlhe gear segments of the higher registering devices are each provided with an upper guide lug 4-9 which is adapted at times to bear against the upper guide face d7 of the companion controlling arm in substantially the same manner in which the upper guide lug d5 of the fractional gear segment bears against its companion arm, the only difference being that the upper guide lug d9 oi the higher gear segments are held out of engagement and separated by a space from the upper guide "face of the companion arm when no number is carried from a lower to a higher registering device. The upper guide lug 49 is held in this elevated position above the adjacent guide face by a rocking latch 50 which is arranged in a notch in the rear side of the gear segment and which normally projects towaro the left and engages with the upper guide face 4:7 oi the adjacent controlling arm, as shown in Fig. 2.

During the ordinary up and down movement of each higher controlling arm and gear segment, the latter is guided by its lower guide lug l6 and the locking latch 50 engaging with the lower and upper faces of the adjacent arm this movement being the same as the movement of the controlling arm and segment of the fractional registering device. Normally the downward movement of the controlling arm is deter l by the position of its companion key lever and this arm in turn controls thc er;-

ent of the downward movement of thegear segment. l/Vhen, however, the locking finger 50 is withdrawn out of engagement from the upper guide face 47 of the arm, the companion gear segment is capable of moving downward independent of the arm until the upper guide lug 49 engages with the upper guide face or' the arm. The extent of this independent movement of the gear segment with reference to its companion arm is equal to one tooth or space of the segment so that by this means the gear segment is enabled to turn the dial pinion one space more than the position of the key lever permits the same to move.

The withdrawal of the locking latch of each higher registering device is controlled by the next lower registering device and the withdrawal of each latch is effected when the next lower registering device has made one complete turn and arrived at zero. Each of the locking latches is pivoted on the right hand side of its adjacent gear segment, so as to turn transversely with reference to the latter. The latch is turned toward the left into its operative position by a spring 51, the movement in this direction being limited by a shoulder 52 arranged on the latch and bearing against the right hand side of the gear segment. 53 is an upright trip plate connected with the lower end of each latch and arranged normally at right angles or nearly so to the adjacent gear segment, when the latch is in its operating position. 54 represents a number of upright trip arms, each of which is controlled by a lower registering device and which turns the locking latch of the next higher registering device into an inoperative position. This arm is mounted loosely with its lower end on the supporting bar 35 and is provided at its upper end with a rearwardly and forwardly projecting hook 55, and in front and below said hook with a bend forming' a bearing finger 5G. 57 represents trip cams arranged on the left-hand side of each registering dial pinion and connected with the adjacent pinion and dial, but separated from the pinion by an intervening space or groove. The face of each of these cams may begin at its lowermost point near the axis thereof and then extend outwardly in a spiral line terminating with its highest point in line with its lowermost point with which it connects abruptly. The trip cam of the fractional registering device has its face divided into eight parts, each pa-rt'of which except the first is arranged oneeighth of a space farther from the center of the cam than the preceding part, while the trip cams of the higher registering devices each has its face divided into ten parts, each part except the first being arranged one tenth of a space farther from the axis of the cam than the preceding part. Each of the trip arms 5% extends upwardly along the righthand side of the trip cam of a lower registering device and its shoulder 56 engages with the face of this cam, while the hook at its upper end extends toward the left and is adapted to engage with the trip plate 53 of the next higher registering mechanism. In the initial position of each trip arm, its shoulder 56 engages with the lowest part of its trip cam, as represented in Fig. 2.

As the trip cam is turned in the direction of the arrow, Fig. 2, at the same time that its .trip plate.

dial and gear pinion are moved forwardly by the adjacent gear segment during the adding operation, the trip arm is moved backwardly by the gradually rising face of the trip cam. During this backward movement of the trip arm, its hook engages with the trip plate 53 of the next higher registering device and is deflected toward the right thereby, the hook being sufficiently elastic for this purpose. After the hook has passed in rear of said trip plate, the hook owing to its resilience springs back to its normal position, so as to stand behind said \Vhen the shoulder of the trip arm reaches the highest part of the face on the trip cam the trip arm has been shifted to its rearmost position. Upon now turning this cam forwardly another space together with its companion dial and pinion, the highest part of the cam is carried from underneath the shoulder of the trip arm and the latter is moved forwardly over the abrupt face of the cam until its shoulder 56 again engages with the lowest part of the cam face. During this movement of the trip arm, its hook strikes the rear side of the trip plate 53 of the next higher registe ing mechanism and turns the same forwardly, thereby disengaging the locking latch from the adjacent controlling arm and permitting the gear segment carrying the trip plate to move forward one space. The forward movement of the trip arm is effected when the dial to which its trip cam is connected has made one complete rotation and again stands at zero, whereby the addition represented by this complete rotation is carried to the next higher registering device. The forward movement of the trip arm is effected quickly by a spring 58, which connects with a stationary cross bar 59 arranged in front of the trip arms. The trip plate 53 of each registering device is so arranged and is of such length that the hook of the next lower trip arm can engage with the rear side of the plate, for disengaging its latch in any position of the gear segment carrying the plate, and in order to accomplish this engagement it is obvious that cams 57 should be constructed so as to give arms 56 the proper throw. If a gear segment is locked in its highest position by reason of none of its companion keys having been de )ressed, the withdrawal of its latch from t 0 controlling arm simply permits the gear segment to drop one space and turn its companion dial pinion forward one space, while in engagement therewith, the movement of this dial representing one number carried up from the next lower dial. If any one of the keys of the key levers has been depressed, so as to release the gear segment and permit the same to move downwardly for effecting an addition, and if during this time the next lower registering device has made a .complete turn, so as to require the carrying up of a number from the next lower registering mechanism, the latch of the higher registering device will be withdrawn while the same is effecting its addition, thereby causing the segment to descend and turn its dial one space in addition to the spaces corresponding to the depression ot'its respective key.

When the locking latch has been withdrawn so as to permit a gear segment to move downwardly one space farther than its controlling arm, the latch remains in this position during the subsequent upward ]movement of the arm and the segment until the upward movement of the arm is arrested by striking the stop bar 32 and the gear segment continues its upward movement 1ndependent of the arm the extent of one space. The gear segment has now reached its highest position and its latch is again swung automatically by its spring over the controlling arm. The controlling arm and gear segment now. remain in this relative position until another number is to be carried up from the next lower registering device.

1 When the controlling arm has been re tracted to its highest position, the adjacent key lever is moved into its normal retracted position, so that its locking shoulder 38 engages with the locking lug 33 ot the controlward movement.

ling arm-and locks the latter against down- The return movement of each key lever is preferably el fected by a spring 60 which connects the upper arm of the key lever with thetransverse shaft 9, as shown in Fig. 2, or with some other convenient part otthe machine. The lower guide lug of the gear segment is not absolutely necessary because the weight of the parts connected with the controlling arm and arranged in-rear of its pivot is sufiicient to I 'raise the arm. but it is preferable to employ I this lower guide lug 1-6 on the gear segment because it compels the arm to raise with the ear se ment and avoids dis laccment of these parts with reference to each other,'and

7 also serves as a stop to limit the upward movement of the gear segment.

The gear pinion and the coiiperating gear segment of the'fractional registering device are so constructed that the fractional dial 'which records the highest number, in this instance the millions of dollars is preferably operated only by the adjacent carrying de vice of the next lower dial and is incapable of being operated directly from the keyboard because it is not provided with a key operating mechanism.

The mechanism whereby the dials are all turned back to zero or the place of beginning after the addition of numbers has been completed is constructed as follows:

61 represents series of feeling rock le vers which are adapted to shift the key levers, so as to permit the gear segments to descend the proper distance for resetting or restoring the main registering dials to zero. Que of these shitting levers is mounted loosely on the supporting bar 35 adjacent to i the left hand side of each of the key levers and is provided on its upper arm with a "forwardly projecting feeling finger 62 and with a shifting finger 63 which extends behind the upper arm of the adjacent key lcver. The feeling levers have their lingers arranged in rear of the total cams 5? and each or these levers is turned so that its upper arm moves backwardly by the upper arm of the adjacent key lever engaging with the shifting finger 63 oi the feeling lever. 6% represents a transverse pull bar arranged in rear of the lower arms of the feeling levers and connected with each of the latter by a pull spring65, as represented in Figs. 2 and 11. This pull bar is connected at its ends to the lower ends of two depending pull or rock arms 66, which are secured at their upper ends to the rock shaft 9, as shown in Fi 11. Upon turning this rock-shaft, so as to swing its depending pull arms backwardly the feeling levers are turned by means o'ftlie springs 65 so as to move the upper arms of these levers iterwardly. This movement of the rock-shaft 9 is ell'eoted by a cam 67, which is mounted on tie left-hand side of the rocking frame 29 and which is constructed substantially the same as the cam 1 which is mounted on the rocking frame 15. As shown in Figs. 7 and 13, this cam is pivoted at its rear end by a transverse pin to the rear portion o1 the rocking tram 29 and is provided at its front end. with an incline or cam face 68 and in rear of the incline with concentric face 69. The cam (37 is pivotally supported on the rocking frame 29 in the same manner in which the like cam 1a is pivoted on its cor responding rocking "frame 15. The cam (37 can be raised and lowered with its front end into an inoperative or operative position this movement being limited by means of a lug 70 arranged on the cam as shown in Fig. 11, and proiecting into a slot 71. in the ad jacent rocking frame in the same manner in which the movement of the cam M is limited. c

During this operation, those gear seg ments which are held or locked in their highest positions, by reason of their dials being at zero, are simply moved forward at the end of the forward movement of the rocking frames, so as to engage with their TGSPGCUVB dial pinions and are again moved backwardly out ofengagement therefrom at the 'end of the forward movement of the rocking frames, without disturbing their re speotive dials. Each of the unlocked gear segments is moved downwardly a number of spaces corresponding to the number which is "registered on its dial, the extent of this movement being controlled by the companion trip cam which arrests the forward movement of the key lever, through the medium of its feeling lever, when the proper stop shoulder of the key lever has been pre sented to the-controlling arm.

Upon now moving the gear segments forwardly in their variously depressed positions and then raising them to their highest position, each depressed gear segment will .turn its dial backward the same number of spaces that the gear segment was depressed.

When all of the dials have been returned to'ze-ro, the shoulders 56 of all the trip arms engage with the lowest parts of all of the trip cams 57.

The. mechanism whereby the positions of the cams 14 and 67 are reversed preparatory to restoring the dials to zero is constructed as follows:

The-cams 14 and 67 drop into their operative position by gravity. Each of these cams is provided in rear of its pivot with a tail 7 5 which is depressed when it is desired to lift the respective cam into its inoperative position. i

7 6 is a shifting lever which is plvoted at its upper endis disengaged from the rear side of thetail on the cam 14 by a spring 77 as shown in 2. The member 7 6 projects in rear of the mam frame so as to be accessible for manual operation. 78 is a shifting lever which is pivoted between its upper and lower arms and arranged with its upper arm in rear of the tail on the cam 67 and normally held in engagement therewith by a spring 7 9, as shown in Fig. 7. 80 represents an elbow lever pivoted below the bottom of the keyboard, as represented in Fig. '7. 81 represents a main line or cord which is connected with the lower arm of the elbow lever 80 and which is provided at its rear end with two branches 82 and 83. The branch 82 con nects with the shifting lever 76 above its pivot, and the branch 88 connects with the shifting lever 78 below its pivot. 84 represents a total or shifting key having a clepending stem which is guided in top and bottom of the key-board and which bears with itslower end against the upper arm of the elbow lever 80. Upon depressing the key 84, "the elbow lever is turned, so as to draw'the cords or lines 81, 82 and 83 forwardly, the shifting lever 76 into engagement with the tail of the cam 14 and lifting the same into an inoperative position, while the shifting lever 78 is moved rearwardly with its upper arm from the tail of the cam 67.

thereby allowing the latter to drop into its,

operative position. Upon depressing the gear segments while the parts are in this shifted position, the segments move downwardly out of engagement withthe dial pinions. After the gear segments have been depressed they are moved forwardly into engagement with their respective dial pinions by an elbow lever which is connected with its lower arm by a line or cord 86 to the rod or bar 7 as shown in Fig.7, or to one of the rock arms 8. The elbow lever is "turned in the proper direction for this purpose by a shifting key 87 having 21 depending stem which is guided in the top and bottom of the keyboard and which bears against theupper arm of the elbow lever 85. After the gear segments have been moved forwardly into engagement with thedial pinions, while in the depressed position, the gear segments are retained in forward position, and at the same time raised until they reach their uppermost position, whereby the dials are turned to zero. The shifting key 87 isnow released which permits the spring 11 to move the gear segments rearwardly out of engagement with the dial pinions. The key 84 is also released, thereby permitting the shifting levers 76 and 7 8 to resume the positions shown in Figs. 2 and 7, leaving the machine in position to resume adding.

Each of the dials is normally held against turning by means of a detent pawl 103 which engages with the front side of its companion gear pinion, as shown in Fig. 2. The pawls 103 of the several gear pinions are mounted on a transverse pawl bar 104,

thereby moving the upper end of h which is supported at its ends by means of two pawl arms 105, which turn loosely upon the supporting rod or bar 35 of the key levers. The pawl arms are moved rearwardly for engaging the pawls of the bar 104 with the .gear pinions by means of springs 106. These springs are connected loosely at their rear ends to the rock-shaft 9 and at their front ends to the pawl arms 105. During the forward movement of the gear segments preparatory to turning the dial pinions, the detent pawls are swung forwardly out of engagement with the dial pinions by means of two shifting rods 107 which are connected at their rear ends to opposite ends of the transverse rod 7 or some part moving therewith and each of which is provided at its front end with a fork or bifurcation 108, which engages with a pin or shoulder 109 on the pawl arm arranged on the adjacent side of the machine. As the gear segments move forward into engagement with the gear pinions the shifting rods 107 move the detent pawls 103 out of engagement with the dial pinions and when the gear segments move backwardly the detent pawls are again engaged wlth the dial pinions by the springs 106, Fig. 7.

Recording mechanism.

For the purpose of recording the numbers which are added together by the above described mechanism a recording mechanism is provided which is constructed as follows 140 represents a printing roller or platen which is arranged transversely in the upper, rear part of the machine and under the lower side of which the sheet or other article is placed which receives the record. 141 represents a number of type segments which are arranged transversely side by side below the platen and which are pivoted at their front ends to the supporting bar 31 upon which the rear ends of the controlling arms 30 are pivoted. Each of these type segments is provided at its rear end with a segmental row of type carriers 142, which are capable of moving radially back and forth on the type segment.

Each of the type carriers is provided at its rear end with a type and is guided upon the type segment by means of screws or rivets 143 secured to the type carrier and arranged in radial slots 144 formed in the type segment, as shown in Figs. 2 and 3. Each of the type carriers is held in its inward or retracted position by means of an S-shaped spring 145, which is arranged between the carrier and the type segment and is secured with one end to the carrier and with its other end to the type segment. Upon raising or lowering the type segment any one of its type can be brought to the printing point or line, and upon striking the back or inner end of the type carrier, when the same is in line with the printing point the type carrier will be driven outwardly and its type will produce an impression on the sheet supported by the platen. After the carrier has received the blow for driving the same against the platen, the carrier is again quickly retracted to its innermost position by means of its spring.

Each of the type segments is connected with one of the controlling arms, so that upon depressing a controlling arm and the registering gear segment connected therewith, the companion type segment will be raised and present one of its type to the printing point.

For convenience in operating the machine, the keys are separated a considerable distance on the key-board and in order to produce a compact record, the printing segments are arranged closer together than the keys and the .registering mechanism. In order to permit of this arrangement, each type segment and its corresponding controlling arm are connected by a connecting arm 146 as represented in Figs. 1 and 2. The connecting arms of the central controlling arms and type segments are comparatively straight, but the connecting arms of the outer type segments and controlling arms are arranged obliquely, the degree of this obliquity gradually increasing from the central type segments and controlling arms in opposite directions toward the outer type segments and controlling arms, as represented in Fig. 1. The connecting arms 146 of the outer controlling arms are arranged in the spaces behind the upright parts and above the horizontal parts of the control ling arms, thereby permitting the inner con trolling arms to move up and down without interfering with the connecting arms 146 of the outer controlling arms.

The types on each type segment are arranged to correspond with the teeth and numbers of its companion gear segments and registering dial, the Zero type being at the upper end of the series and the progressively higher. digits arranged in their order downwardly from the zero type. When the registering gear segment is in its highest position it presents its zero tooth to the dial pinion, and the type segment which at this time is in its lowest position presents its zero type to the printing point. Upon depressing a gear segment so as to present one of its higher teeth to the dial pinion, its companion type segment is raised proportionally and presents a corresponding higher numbered type to the printing point.

147 represents a number of hammers whereby the type carriers are struck for driving the type against the platen. One of these hammers is arranged adjacent to each type segment and is provided with a head which is arranged in front of the series of types and in line with the printing.

point of theplaten. Upon shifting the type segment so as to bring one or another of its type carriers to the printing line andthen operating the hammer, the latter delivers a blow against the inner end of the particular carrier which is at the printing point and produces an impression of its type on the platen. The several hammers are pivoted on the transverse rod 12, arranged in [rear of the segments; and each of the hammers is yieldingly held in its forward position by a spring 148 connected at its lower .end to a cross bar 149 and at its upper end its ends upon the rear ends of rock arms printing point.

152 which turn loosely with their front ends on the rod 31 supporting the type segments and controlling arms.

153 represents a number of hammer or trip pawls, whereby the hammers are retracted preparatory to delivering a blow against the type carriers whlch are at the ranged adjacent to each hammer and pivoted loosely at its lower end to the trip bar 151, and its upper end is provided on its rear. side with a downwardly facing hook or shoulder 154, and above said shoulder with a trip face'155, as shown in Figs. 3 and 6. Each of the hammers is provided in front of its pivot adjacent to the upper end of the hammer pawl with a lower trip lug or shoulder 156 and an upper trip lug or,

shoulder 157. When the parts are at rest, the hammer pawl. 153 is raised into its highest position and the hammeris in'its normal position with its lower trip lug 156 below and in rear of the hook of the hammer pawl and with its upper shoulder 157 in rear of the trip face of the hammer pawl, as represented in Figs. 2, 3, and 4.

Upon shifting the hammer pawl rearwardly, while the parts are in this position,

7 tinued downward movement of the hammer and itspawl, this upper shoulder gradually crowds the hammer pawl forwardly with reference to the hammer by reason of the hammer and its pawl swinging on different One of these pawls is ar-' centers. During the last portion of the downward movement of the trip bar 151 and tent that its hook is disengaged from the lower shoulder 156 of the hammer, thereby liberating the latter and permitting its spring 148 to throw the same quickly and deliver a'blow against the type carrier at the printing line. The trip bar 151 now rises and carries the hammer pawl into its highest position, preparatory, to again engaging the hammer for depressing the same.

158 represents a number of upright shifting arms whereby the hammer pawls are moved rearwa-rdly, so that their hooks engage with the lower shoulders of the hammers. ()ne of these arms is arranged adjacent to each hammer pawl, as shown in Figs. 3, 4 and 6 and is pivoted at its lower end on the trip bar 151, and its upper end is provided with a roller or projection 159 which bears against a hammer cam 160 on the lower part of the adjacent type segment, as shown in Fig. 3. This'hammer cam is provided at its upper end with a receding or low portion, an inclined portion arranged below the low portion, and a concentric or high portion arranged below the inclined portion. :Each shifting arm 158 is moved forwardly and its roller is yieldingly heldin engagement with the adjacent hammer cam by a spring 161 connecting said arm with a cross bar 162 secured to the rock arms 152. The backward movement of each hammer pawl with reference to its companion shifting arm, is limited by means of a stop 163 secured to the upper portion of the hammer pawl and en gaging with the front side of the shifting arm, as represented in Figs. 3, 4 and 5.

Each hammer pawl is yieldingly held in its rearmost position with reference to its shifting arm by means of a C-shaped spring 164 secured with its ends, respectively, to the hammer pawl and its shifting arm, as shown in Figs. 2, 3 and 4. In the lowermost position of a type segment the receding part of its cam is presented to'the roller of the shifting arm 158, which permits the hammer pawl to be retracted into its foremost position, as represented in Fig. 2. Upon depressing the trip bar 151 when the parts are in this position, the roller 159 is not engaged soon enough by the incline of the cam 160 to engage the hook of the hammer pawl with the lower shoulder of the. hammer,before the hook has passed below this shoulder but instead, the trip face of the hammer pawl slides idly against the shoulder 156 without retracting the hammer, whereby no impression of the particular type at the printingline is produced. If the type segment is raised, so as to present one of its lower types to the printing point or line, the incline of its cam, during the first part of the upward movement of the segment, moves the shifting arm 158 rearwardly together with the hammer pawl yieldingly connected therewith, so that the hook of the hammer pawl stands over the lower shoulder 156 of the hammer. Upon now depressing the pawl 153 the hammer will be retracted and released near the end of the downward movement of the pawl and will be quickly swung up by the spring 1 18, thereby delivering a blow against the type at the printing point and producing an impression thereof.

The incline 160 of the type segment cam is so constructed that it throws the hammer pawl backwardly into an operative position when the segment is raised one digit space, and during the continued upward movement of the segment, the hammer pawl is held in this operative position by the high concentric part of the segment cam. By thus constructing the type segment cam its companion hammer pawl is not shifted when the segment is not raised and its zero type remains at the printing line, but the hammer pawl is shifted into an operative position for producing an impression, if the type segment is raised one or more digit spaces and presents any one of its digits higher than zero to the printing line.

Automatic printing of zero.

165 represents a number of transfer or coupling fingers which enable the ciphers in a number to be printed automatically. One of these transfer fingers is secured to each of the shifting arms 158, as represented in Figs. 3 and at, and extends laterallytoward the right therefrom into engagement with the shifting arm of the next lower hammer pawl, as represented in Fig. 13. If any one of the printing segments remains in its lowest position, so that its cipher remains at the printing line and the next higher printing segment has been raised for printing a hi her number or digit, the transfer finger or the higher hammer shifting arm 158 while being moved rearwardly by the cam of its companion printing segment, is caused to engage with the shifting arm 158 of the next lower hammer pawl and shift the latter backwardly, so that its hook is carried baclnvardly over the lower shoulder of the companion hammer. Upon now depressing the trip bar 151, the higher hammer pawl 153 is coupled with its hammer, and the next lower hammer pawl is also coupled with its hammer, whereby an impression of the cipher or zero type on the lower se ment is produced on the platen at the same time that the next higher number is printed on the platen.

If two ciphers occur in succession in the body of a number the shifting arm to the left of the highest order printing segment to be operated for printing a zero sets the hammer mechanism of said highest zero-printing segment by means of the transfer finger of said shifting arm and the shifting arm of said highest zero-printing segment in turn by means of its transfer finger sets the hammer mechanism of the printing segment of next lower order, etc. This operation of producing an impression of the cipher type is effected automatically and renders it possible to print any number of ciphers in succession in the body of a number because the hammer operating mechanism of each segment which remains standing with its upper type at the print ing line is controlled by the hammer operating mechanism of a higher type segment and in turn controls the hammer operating mechanism of the next lower type segment if the next lower segment presents a cipher to the printing line.

Only the ciphers below the highest digitin the number to be recorded are thus printed automatically because the printing of a digit depends upon the upward movement of a printing segment, thereby avoiding the printing of ciphers ahead of the highest digit in the number to be recorded. The hammer shifting device of the segment which prints the numbers representing units of cents is preferably not pro -rided with a transfer finger to operate on the hammer shifting device of the segment which prints fractions of a cent, because it is proper that the space to the right of the lowest integer shall remain blank when no fraction is recorded therein.

The c! ying bar 151 is raised by one or more spr n s 165 which connect this bar with the t isverse rod 12, and the upward movement of the bar 161 is arrested when the hammer operating pawls reach their highest position by a transverse bar 16 which is engaged by he rear ends of the rock arms represents a coupling hook, whereby the hammer trip devices are depressed. This hook is pivoted with its upper end to the trip 151 and its lower engaging end is provided with a notch having upper and lower shoulders.

In the lowered position of this hook its notch engages with a cross bar 169 which is conne ted with. the rock arms 24;, as represented i F g. 2, so tiat the hook and hammer opei mg devices connecting therewith are actuated from the rocking frames 15 and 29,through the medium of the rock arms 24E. In the r armost position of the rocking f: front nds of their notches 28 the it side of the bar 25 to s ants are yieldingly con- 55 engagement with the respective cams 57 and rear shoulders of the notches 28 in the rocking frames engage with the cross bar 25, so that thereafter this bar is carried down wardly with the rocking frames and the gear segments are depressed. During this downward movement of the bar 25 with the rocking frames, the companion bar 169 moves down idly in the notch 'ofthe hook 168 until this bar engages with the lower or front shoulder of this hook. After the cross bar 169 engages with the lower shoulder of the notch of the hook, the latter and the hammer operating devices connected therewith are moved downwardly with the rocking frames until these frames reach the end of their downward movement. During the last portion of the downward movement of the rocking frames the hammer pawls are disengaged, as before described, from the retracted hammers, whereby the latter are released and strike the type carriers which shown in Fig. 8, so that the types are moved outwardly by the impact of the hammers and are then returned by their springs so as to clear the printing surface.

When it is desired to print or record the total at the foot of the column of the numbers which have been printed, the operation is as follows :-The total key 8d is first depressed, thereby raising the cam 14 into an inoperative position and lowering the cam 67 into an operative position. Upon now moving the rocking frames 15 and 29 forwardly the feeling levers 61 are turned so as to move'their feeling fingers forwardly into at the same time each feeling lever carries the adjacent key lever forwardly so that its particular stop shoulder 39 corresponding to the position of the tri cam 57 and its dial is moved into the path of the stop lug 34 of the controlling arm. After the key levers have been thus shifted forwardly into their respective positions corresponding with their dials, the continued forward movement of the rocking frames causes the gear segments while in a retracted position out of engagement with the dial pinions to be depressed until each segment is arrested by the engagement of the stop lug on its controlling arm with the respective stop shoulder of its key lever, whereby each printing segment is raised so as to present the type carrier to the printing point which carries the type corresponding to the number registered on its companion dial. During the last part of the forward and downward rocking movement of the rocking frames the hammers are operated and the particular type at the printing line are impressed on the platen. Upon now swinging the rocking frames backwardly, the gear segments are raised while still in a retracted position out of engagement with their companion dial pinions, thereby permitting further numbers to be added to the total already registered on the dials. If however, it is desired to turn the dials back to Zero, after the total of the added numbers has been printed or recorded the gear segments, while in the retracted lower position which they occupy while printing the totals, are moved forwardly into engagement with their respective dial pinions by the depression of the key 87. Upon now moving the rocking frames backwardly the gear segments are raised while in their forward position in engagement with their pinions, whereby each of the latter is turned backwardly and when the segments reach the end of their upward movement, the dials have been turned backwardly a number of spaces corresponding to the number on the dial, thereby turning all of the dials to zero. 1

Vertical ruling.

Mechanism is provided whereby vertical ruling may be produced on the recording surface, this mechanism being constructed as follows 203 represents an upright ruling lever which turns loosely on the supporting bar 12 and which is arranged between the dollars and dimes printing segments, as shown in Figs. 1, 11 and 13. The upper arm of the ruling lever is provided with a vertical ruling blade 204 which is arranged close to the platen when in its upper position. The ruling lever is yieldingly held in this position by means of a spring 205 connected with the lower arm of the ruling lever and the movement of the latter toward the platen is limited by the engagement of its lower arm with the rear side of a rubber buffer 206 on the cross bar 167 similar to the rubber 170. 207 represents a pawl whereby the ruling lever is retracted and then released for permitting the same to deliver a blow against the recording surface for producing a vertical ruling impression thereon. This pawl is pivoted at its lower end on the cross bar 151 and is yieldingly held with the hook 208 on its upper arm in engagement with a shoulder 209 on the ruling lever by means of a spring 210 which connects the lower arm of the ruling lever with the rod 162.

In the uppermost position of the bar 167 the ruling pawl engages the shoulder of the ruling lever and upon depressing this bar, the ruling lever is pulled downwardly by the ruling pawl. During this downward movement of the rulling lever and pawl, the front side of this lever engages with the upper arm of the pawl, and gradually crowds the pawl forward until the pawl is disengaged from the shoulder of the lever. Vhen the ruling lever is thus released from the pawl, the lever is quickly turned by the spring 205 in a direction for throwing its upper arm upwardly, whereby its blade delivers a blow against the recording sheet or surface on the platen and produces a ruling impression thereon. During the last portion of the subsequent upward movement of the ruling pawl 207 its hook again engages over the shoulder of the ruling lever. This construction of vertical ruling devices produces the vertical ruling in sections by successive blows of the ruling blade.

If desired vertical ruling may be produced by holding a stylus or lead pencil 211 against the recording surface by means of a stationary holder 212, as represented in Fig.

9, whereby continuous ruling is produced on the recording surface or sheet as the sheet is fed past the same.

Vertical ruling may also be produced by a ruling disk 213 arranged to bear with one side against the recording surface and an inking wheel 214 supplying the ink to the edge of the ruling disk, as represented in Fig. 10.

Fla-ten mechanism.

The mechanism whereby the platen is supported and operated and the sheet or other impression surface which receives the record is presented to the printing line, is constructed as follows The frame of the carriage which supports the platen, paper and inking device consists of a transverse supporting sleeve 260 arranged in rear of the printing mechanism and provided at opposite ends with two upby means of a catch 261 which engages with its front hooked end over a transverse rod 265 arranged below the platen and secured with its ends to the sides of the main frame, as represented in Figs. 1, 2 and 13. This catch is yieldingly connected with the paper carriage, so as to permit the platen to recede more or less from the printing mechanism for the purpose of adjusting the platen to the thickness of the sheet of paper or other object which receives the impression and which is interposed between the platen and the printing types. This yielding connection forms no part of the invention claimed in the present application and will therefore not be described in full. This matter is fully described and claimed in my pending divisional application Serial No. 243.4% to which reference is hereby made. For the purpose of the present application any suitable means may be employed for the purpose of holding the platen in. printing relation with the printing types.

The record-sheet is fed forwardly underneath the platen and upwardly in front of the same, so that the sheet passes the printing line. The sheet is pressed against the underside of the platen, in rear of the printing line, by a transverse presser roller 270 arranged below the platen and journaled with its ends in the front arms 261 of the paper carriage.

Platen feed 07* Zine-spacing.

283 represents a platen feed lever which is pivoted loosely on the left end of the platen shaft and which is provided on its rearwardly projecting arm with a pawl 284 which engages with a ratchet wheel 285 secured to the adjacent end of the platen, as represented in Figs. 1 and 7. 286 represents an intermediate actuating lever which is pivoted on the lower part of the front carriage-arm 261 which is adjacent to the ratchet wheel 285. The ratchet lever is connected with the intermediate lever by means of a link 287 which is pivoted at its upper end to the rear arm of the ratchet lever and is provided at its lower end with a loop 288 which receives the rear arm of the in termediate lever. 289 represents a spring which connects the front-arms of the ratchet lever and intermediate lever. The upper end of this spring is connected with the front arm of the ratchet lever a greater distance from the pivot of the latter than the distance between the connection of this spring with the intermediate lever and the pivot of the latter. By this connection of the spring 289, the leverage of the ratchet lever is greater than that of the intermediate lever, which causes this spring, when both of these levers are free, to turn these levers simultaneously in the direction for raising their rear arms, thereby moving the ratchet pawl upwardly or backwardly for Y taking'up a new tooth on the ratchet wheel.

i 0f a-spring 290. The movement of the intermediate lever in the direction for raising its rear arm and moving the ratchet pawl backwardly' is limited by means of a nose 291-formed on this lever and engaging with a stop on theadjacent arm of the carriage,

as represented in F ig. 7 r

The rocking motion of the intermediat 'lever'is always the sameyand in order to enable the same to turn the platen different distances, the rear arm of the intermediate lever is provided on its under side with a number of notches 292 which are arranged "different distances from its fulcrum, and

one or another of which is engaged by the lower end of the loop 288 on the connecting 1ink287; Upon engaging this loop with the 'notch of the intermediate lever nearest its axis, the ratchet pawl is shifted so that the platen is turned one line-space at a time; while upon shifting this loop into engagement with one of the outer notches of the intermediate lever, the platen will be turned forward by its ratchet mechanism a correspondingly greater distance by the operation of the machine.

The intermediate lever is turned in the direction for shifting'the platen by a transverse bar 293 arranged below the front arm thereof, as represented in Figs. 1, 2, 7 and .13. This bar is supported upon the upper ends of two rock arms 294 which are mounted loosely with their lower ends on the cross bar 167. 295 represents a depending arm which is preferably formed in one piece with that'one of'the arms 294 arranged on the left'hand side of the machine.

This depending arm is provided with a nose which is arranged in rear of and in the path of the rocking frame 29.

j During the last portion of the rearward movement of this rocking frame, it engages with the nose of the depending arm 295 and moves the same rearwardly, and the upper arms 294 connected therewith are moved'forwardly, thereby causing the crossbar 293 to be carried upwardly and turn the intermediate lever in the direction for feeding the platen and paper forwardly. During the forwardmovement of the rocking frame 29,the rock arms 294 are turned backwardly together with the intermediate lever and connecting parts by the spring 289 preparatoryto feeding the platen forward the next space. As the line-spacing of the record sheet by feeding the platen occurs after each item is printed and in the same operation in which said item is printed, the printed record is fed up into visible position at each operation of the machine.

If desired, the platen may be turned by hand when it is desired to adjust the paper, thisbeing effected by releasing the pawl 284 from the ratchet wheel and then turning the platen by means of a button 296 secured to one end of the shaft as shown in Figs. 1, 11 and 13.

The cross bar 293 extends a sufficient distance transversely of the machine so as to engage with the front arm of the intermediate rock lever 286 in all the positions to which the paper carriage can be shifted transversely in the machine.

' H orieontallg movable carriage.

The paper carriage is capable of sliding lengthwise on the rods 263 and 265 for presenting different parts of the paper to any particular type and is held in its adjusted position by a spacing device which consists of a graduated adjusting sleeve 301 and an adjusting catch 302, as represented in Figs. 2 and 12. The adjusting sleeve is revolubly mounted on the supporting sleeve 260 be tween the carriage frame arms 261 and is provided with two or more longitudinal series of stop notches or graduations 303, 304. The notches in each series may be equidistant and the notches in one series are spaced different from the notches in the other series, as shown in Fig. 21. The catch 302 is pivoted on the rod 167 and is yieldingly held in engagement with any one of the notches in the adjusting sleeve 301 by a spring 305. When it is desired to shift the carriage intermittently short distances lengthwise of the platen for writing narrow columns, the adjusting sleeve is turned so as to present its closely spaced notches to the catch, and the latter is shifted from one of these notchesto anotheras the writing progresses. When wider columns are to be written the adjusting sleeve is turned so as to present correspondingly wider spaced notches to the catch. As shown in the drawings, only two series of adjusting notches are provided on the adjusting sleeve, but more series of notches may be provided if necessary. 0
