OE DAYTON, OHIO, A CORPORATION OF TOTAL-PRINTING MECHANISM FOR CASH REGISTERS;

Application filed August 16, 1915, Serial No. 300,775. Renewed May 29, 1919.

This invention relates to accounting machines and the like and more particularly to the total printing mechanism therefor.

One object of this invention is to construct improved means whereby the differential mechanism is controlled. by manipulative means upon adding operations ofthe machine and by the totalizer upon total printing operations ofthe machine.

Another object of the invention is to provide a novel arrangement of type carriers, adapted to printitems entered in the totalizer, and additional type carriers which are of higher orders and operated during adding operations by the t-otalizer element of highest order when transfers from the latter are required, the latter type carriers together with the former being adapted to print totals.

A still further object of the invention is to turn the totalizer elements to zero and to provide means for turning to zero the additional type carriers of higher orders.

Still another object of the invention is to construct the impression means so that the additional type carriers of higher orders only print on the record material during total printing operations of the machine.

With these and incidental objects in view, the invention consists in certain novel fea tures of construction and combinations of parts. the essential elements of which are set forth in appended claims, and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form part of the specification.

Fig. 17 is a detail view showing the type carrier for printing characters designating the classes of transactions.

F ig. 18 is a detail view showing a portion of the detail strip printed on by the machine. Described in general terms, the machine comprises several banks of manipulative devices Which control the differentialmove ment of actuating segments or devices, the in turn, operating the indicating and registers mechanisms; The saturating ments are coupled to the oriving mechanism by latches which, in adding operations, are operated by contact with the keys to disconnect the actuating se ments from the driving *mechanism. Each actuating segment, through intermediate gears and pin ions, imparts differential movementto two gears associated with the appropriate totalizer element, the two gears being rotated in opposite directions. in adding operations, the totalizer elements are each connected by broad pinions to that one of the two gears which rotates in the adding direction so that the items set up on the keys are accumulated on the totalizer. Preliminarily to operation of the machine for printing a total, the broad pinions are shifted so that they operate to couple the totalizer elements with the which are reversely rotated upon diflerential movement of the actuating segments from zero position to restore the totalizer elements to zero. The totalizer elements, upon reaching zero positions, control mechanism which operates the above mentioned latches to disconnect the actuating segments from the driving mechanism.

Type carriers are differentially positioned in accordance with the amount set up on the keys in adding operations and in accordance with the amount standing on the totalizer elements in total printing operations. The totalizer elementof highest order actuates additional. type carriers when transfers from the highest order totalizer element are necessary, no banks of amount keys being provided for these additional type carriers. The impression means is so constructed that upon adding operations only, the type carriers coi'itrolled by the depressed keys print upon the detail strip. When a total is to be printed, however, the impression means is adjusted by the means for preparing the machine for total printing operations so that upon operation of the impression means during the operation of the machine the type carriers, controlled by the keys during adding operations and by the totalizer elements in total printing operations, together with the above mentioned additional type carriers, print tire totals accumulated on the totalizer. When the means for preparing the machine for total printing operations is manually restored to normal position after the machine is operated, this means actuates a device for resetting the additional type carriers to zero.

Manipulative devices, such keys 20 (Figs. 1 and 3), are arranged in groups or banks and when depressed agai st the tension of their springs, are latched in depressed positions by detents 21-, there being one detent for each bank of keys. The forward ends of the detents 21 are elevated when keys are depressed, and the detents are locked in elevated positions during the operation of the machine by latch plates 17 (Fig. 1) moved rearwardly by their springs 18 to carry their shoulders 19 under the forward ends of the detents 21 when the delents are elevated. Each detent 21 is provided with a stud 22 which engages the forward end of a corresponding arm 23 fast on a shaft 99 so as to rock this shaft against the influence of a spring 25, connected at its upper end to one of the arms 23 and at its lower end to a shaft 34:. The shaft 99 extends horizontally through the machine and is provided at its right hand end with a rearwardly extending arm 26 which has, at its extreme rearward end, a verticalprojection normally engaging a recess 27 formed in the periphery of a disk 28 fast on a shaft 29. A main drive shaft 30 is given one complete rotation counter-clockwise (Fig. 1) by a crank handle or other desired means upon each operation of the machine, and the shaft 29 is given one complete rotation in a clockwise direction (Fig. 3) upon each operation of the machine, by the shaft 30 through suitable gearing (not shown). From this description it can be seen that the operating mechanism will be locked against operation by the arm 26 until one of the keys is depressed to move the projection on the arm 26 out of the recess in the disk 28.

Rigidly mounted on the shaft 30 is a crank 31 (Fig. 1) connected by a link 32 to an arm 33 fast on the shaft 34. As the crank 31 is shorter than the arm 33, the rotation of the shaft 30 rocks the shaft 34 first counterclockwise as viewed in Fig. 1, about 90 degrees and then clockwise to normal position. F st on the shaft 3 1 are driving segments 36, one for each bank of keys. hen the shaft 3% and the segments 36 are rocked counter-clockwise, shoulders 37 formed on the segments will be engaged by projections on the rear ends of latches when the shoulders are brought opposite the projec- 'tions. The latches 38 are pivolally hung by links 39 on actuating segments 10 loosely mounted on the shaft 34:. Bell cranks 420 are pivoted at 421 to the respective actuating segments 40 at points adjacent the respective latches 38, one arm of each bell crank being pivotally connected by a pin 41 to its latch, and the remaining arm of each bell crank carrying a spring-pressed pawl 42 pivoted thereto and projecting beyond the pathof travel of its actuating segment ll). Upon return clockwise of the segments 36, the actuating segments lt) carrying the latches 38 of the bani s l11.WlllCl1 keys are depressed, will be carried with the segments 36 distances determined by the value of the keys depressed, the inner ends of the depressed keys lying in the paths of the pawls 42 to arrest the latter, the effect being to draw the latches 38 forwardly and thereby disconnect the driving segments 36 from the actuating segments 40. Projections 35 on the latch plates 17 (Fig.1) appropriate to the banks of keys in which no keys are depressed, engage the pins ll on the latches 38 and if the actuating segments l0 are already in zero positions, prevent the latches from being operated to connect the actuating segments and driving segments 36. If an actuating segment 10 has been moved out of zero position at the preceeding operation of the machine, its latch 38, when moved to zero position, is operated by the projection on the latch plate 17 if a key in the corresponding bank is not depressed, and therefore, the actuating segment is disconnected from its driving segment 36. Near the end of the operation of the machine, the opera-ted latch plates 17 are restored to their normal positions by the segments 36. This construction is well known in the art and is fully shown and described in the above mentioned patent to Cleal and Reinhard, and therefore has not been described in detail here. i

The actuating segments 40 are provided with teeth s l which mesh with gears 45, these gears in turn, meshing with smaller gears 46 secured to indicators 47 mounted loosely upon a transverse rod 48.

The gears also mesh with gears 41-9 (Figs. 1, 5, and 8) rigidly connected by pins 50 (Fig. 8) to gears 51 loosely mounted on sleeves 52, rotatable on a shaft Totalizer elements or disks 5% are integral'with the sleeves 52 and are connected to gears 55, adjacent the gears 51, by pins 56. The totalizer disks 54 do not have the usual numerals on their peripheries, but these nu.- merals maybe placed thereon if desired and may be viewed through openings in the cabinet. In the illustrative form shown in the drawings, however, these nmnerals have been omitted as the total accumulated on the totalizer elements is printed upon total printing operations. The gears 51 and 55 are normally disconnected and just previous to the clockwise movement 1) of the actuating segments 10,they ar'econnected by broad pinions 59 and 5), there being one pinion for each totalizer disk 54:, so th at the differential movement of the actuating segments it) will be imparted to the tote-liner disks 5st through 45, 4:9, 51, and pinions 59. These broad pinions 59 are mounted in the upper-ends of arms 60 secured to a shaft (it. A downwardly extending arm 63 (Fig; 2) is spiined on the shaft 61 so that the shaft 61*rocks with the arm, but may be shiftedlaterall ii lependently of the arm. The lower end of the arm 63 is pivot-ally connected to the forward end of a pitman 64; which, at its rear end, is forked to embrace the drive shaft 30 and carries a roller projecting into mounted on the shaft 29.

a cam groove formed in the face of disk 67 fast on the shaft 30. The shape of the cam groove in the dlsk 67 s such that ust before the actuating segments 40 begin their clockwise movements (Fig. 1) from zero positions, the pitman (i l will be thrust forwardly (to the left in Fig. 2) to rock the broad pinions 59 into engagement with the corresponding pairs of pinions 51 and to connect them for movement together. The actuating segments 10 are moved counterclockwise to their zero positions at the be ginning of each operation of the machine try-extensions or flanges 68 on the regments 36 which contact theactuating segments l0 and rock them counterclockwise to their normal positions. -During this movement of the actuating segments, the broad pinions 59 are out of mesh with the 51 and 55.

Any suit-able transfer i'nechanism may be employed. None is shown, it is not essential to an understanding of this invention. 1 d The gears 45 are fast on the right hand ends of nested sleeves 70 (Figs. 1,10 and 16), which surround the shaft 29, and the opposite ends of the sleevescarry printing segments 71 forfirecording items and totals upon a detail strip 72 (Figs. 16 and 18). The detailstrip is fed from a supply roll 73 over platens 74: and 75 (Fig. 10) and thence to a storage roll 76 (Fig. 16). g The detail strip is carried on a frame 77 having an arm 78 (Fig.10) slidably mounted in a stationary frame 7 9 mounted on the left hand side frame of the machine. The platens 7 1 and 75 are fast on a shaft 80 journalledin the frame 77. The arm 7 8 carries a roller 82; (Fig. 10) projecting into a cam groove'formed in a disk 83- rigidly The shape of the cam. groove in the disk 83 is such that, upon rotation of the shaft 29, the frame 77 carrying the platens and the detail strip will be first lowered to feed the detail strip and permittheinking of the type carriers and i then be raised to take an impression upon a check strip, after which it is lowered to permit thecojectionof the check and is finally raised to take an impression upon the detail strip 72. The previously mentioi'ied check strip not shown in the present drawings, it being suflicient to state here that it is fed over the platen 74!; so that when the platen 7st first raised, an impression will be taken from the type carriers and a portion of the check strip will be severed whereupon a check ejector 84- (Fig. 16) grips the check and ejects it froin the machine as the frame 77 is lowered.- Previous to the printing of the check, an ink pad 85 carried by arm scribed is practically the same as that shown and described in the above mentioned Cleal and Reinhard patent. The improvements applied to this type of machine will now be described in detail, but it is to be understood that these improvements are not to be limited to the particular type of machine to which, for illustration, they have been shown as applied.

Rig-idly mounted on the gears 45 are circular plates or racks 88 (Fig. 1) having on their outer peripheries a set of teeth 89, a set of teeth and V-shaped aligning notches 91. The teeth 89 and 90 of each plate 88 mesh with a corresponding pinion 92 rigidly connected by its hub 93 (Figs. 5 and 7) to a pinion 94. The pinions 92 and 94 are loosely mounted on a cross rod 95 projecting through the machine. Each pinion 94 meshes with a gear 96 (Figs. 5 and 8) loosely mounted on the hub of the corresponding gear 55. Through these connections the differential movements of the actuating segments 40 are imparted to the gear wheels 96, the direction of movement of the gear wheels 96 being reverse to that of the gear wheels 49 and 51. In adding operations the broad pinions 59 only mesh with the pairs of gears 51 and 55 so that the gears 96 rotate idly upon the hubs of the gears 55.

When a total is to be printed, the shaft 61, and therefore the broad pinions 59, are shifted towards the left preliminarily to the operation of the machine, as will be presently described, so that when the shaft 61 is rocked by the cam 67 (Fig. 2), the broad pinions will mesh with the pairs of gears 55 and 96 but not with the gears 51, and therefore, the gears 49 and 51 are idly ro tated during total taking operations of the machine. As the gear wheels 96 are rotated reversely to the gear wheels 51 by the actuating segments 40 through the gears 45 and pinions 92 and 94, the totalizer disks 54 are rotated reversely to their zero positions when the pinions 59 are moved into engagement with the gears 55 and 96 during total printing operations.

hen the totalizer disks 54 reach their zero positions, the latches 38 (Fig. 1) are op era-ted to disengage the actuating segments 40 from their driving segments 36. The means for effecting this disconnection of the actuating segments from their driving segments under the control of the totalizer disks will. now be described.

Loosely mounted on the shaft 99 are a number of arms 100 (Figs. 1, 6 and 9),, one for each of the totalizer disks 54. The arms 100 are held against lateral movement on the rod 99 by collars 106. Springs 101 connected at their lower ends to the forward ends of the arms 100 and at their up per ends to a cross rod 102, normally retain the upper edges of the arms 100 in contact with the shaft 61. The arms 100 camry studs 103 which project through slots 104 in the corresponding levers 105. The studs 103 are so constructed that the levers 105 are prevented from moving laterally of the arms 100. The shaft 61 projects through recesses 107 formed in the levers 105, the latter be ing slidably mounted on the shaft 61 and the studs 103 so that they can be moved rearwardly. The shaft 61 is also free to be shifted independently of the levers 105. hen the shaft 61 is shifted to move the pinions 59 into position to engage the pairs of gears 55 and 96 during total printing op erations, hubs 108 (Figs. 5 and 6) integral with the pinions 59, are moved in front of the vertical arms of the levers 105 so that when the shaft 61 is rocked to move the pinions 59 into mesh with the pairs of gears 55 and 96, the hubs 108 contact the levers 105 ant. slide the latter rearwardly on the shaft 61 and the studs 103. Projecting laterally from the totalizer disks 54 are pins 110 which, when the totalizer disks approach their zero positions during total printing operations contact shoulders 111 on the le-' vers 105 to rock the levers clockwise (Fig. 6) about the shaft 61. During adding operations the levers 105 are not moved rearwardly, and therefore the pins 110 on the totalizer disks do not strike the shoulders 111.

When one of the levers 105 is rocked clockwise (Fig. 6) by the pin 110 on the corresponding totalizer disk, as above described, it rocks the corresponding arm 100 counter-clockwise, as the stud 103 on the arm projects through the slot 104 in the lever 105. When the arm 100 is rocked in this manner, its downwardly extending projection or foot 113 is moved into the path of movement of one of the shoulders 114 formed on a sliding arcuate plate 115. Each plate 115 is slidably mounted on. the corresponding actuating segment 40 by pins 116 which project from the actuating segment through slots in the plate 115. A spring 117, which is connected at its forward end to a hook 118 on the plate 115 and at its'rear end to a pin on the actuating segment 40, serves to retain the plate 115, relatively to the segment 40 in the position shown in Figs. 1 and 6. When the projection 113 of the arm 100 is moved into the path of movement of one of the shoulders 114 on the plate 115, the shoulder engages the projection, thereby arresting the plate 115, while the segment 40 is permitted to move slightly further, this additional movement being permitted by slot and pin connections between the segment 40 and the plate 115. During this slight additional movement of the segment 40, the pawl 42 (Fig. 1) contacts the lower end of the plate 115 to cause the latch 38 to disconnect the actuating segment 40 from driving segment 36. iiireni his new struction it can be seen that when a totalizer disk 54 arrives at zero position during total printing operations of the machine, the corresponding actuating segment 40 is ositively arrested under the control of the totalizer. disk, the segment having moved an eX- tent commensurate with the amount standing on the totalizer disk at the beginning of the operation of the machine. Movement of the actuating segments, under the Control of the totalizer, positions the type segments 71 as in adding operations, to print the total standing on the totalizer disks. The additional movement of the segments 40 relatively to the plates 115 is very slight, being just sutlicient to effect the operation of the latches 38. This additional movement moves the totalizer disks 54 slightly past zero position and the type segments slightly past their proper printing positions, but movement of the forward ends of the latches 38 into the aligning notches 119 moves the actuating segments, the type segments and totalizerdisks back to their proper positions.

\Vhen the broad coupling pinions 59 are rocked out of engagement with their corresponding pairs of gears and 96, springs 120 (Fig. 6) connected at one end to the rod 102 and at their opposite ends to the levers 105, serve to draw the levers forwardly to their normal positions. At the same time, the springs 101 restore the arms 100 to their normal positions, thereby moving the projections 118 out of engagement with the shoulders 114 on the plates 115, whereupon the springs 117 move the plates 115 to their normal positions relatively to the actuating segments 40. J i

The V-shaped ends of aligning arms 122 (Fig. 1) fast on a shaft 1123, engage the notches 91 or between the teeth 90 to align the gears 45, and therefore, the indicators and the type segments in adjusted positions while impressions are being taken from the latter. In case movement of the forward ends of the latches 38 in the notches 119 fails to move the actuating segments 40 and gears 45 back to their proper positions after they have been given the above mentioned additional movement in total printing operations, the arms 122 will accomplish this return movement when moved into aligning positions. The shaft 1123 is rocked by means which is not shown in the drawings but well known in the art, to move the aligning arms 122 into and out of aligning positions at the proper times. The pinions 92 (Fi 1 and. 7) have several alternate teeth cut away so that the pinions may properly mesh with the teeth 90. Each pinion 92 is also provided with a recess 123 so that it may pass over the foremost tooth 90, which tooth is enlarged to contact the aligning arm 122 if the actuating segment 40 should be overthrown slightly past zero position,

whereby overthrow of the differential mech anism past zero is prevented. It is understood, of course, that when the aligning arm is out of aligning position it is still in position to be engaged by the enlarged tooth 90. In order to align the totalizer disks 54 in their proper positions during adding opera: tions of the machine and to prevent reverse movement of the disks during such opera tions, the lower ends of levers 125 (Fig. 6), loosely mounted on the rod 95 co-operate with ratchets 126 fast on the sleeves integral with the totalizer disks. Compressed springs 127 serve to retain the levers 125 in engagement with the ratchets 126. For the purpose of rocking the levers 125 out of engagement with the ratchets 126 during total printing operations to permit backward movement of the totalizer disks, arms 128 fast on the shaft 61 co-operate with arms 129 fast on the levers 125. As shown in Fig. 9, the arms 128 normally do not project over the arms 129 and therefore, during adding operations, the arms 128 are rocked idly with the shaft 61. lVhen theshaft 61 shifted preliminarily to total printing operations, the free ends of the arms 128 are moved over the free ends of the arms 129 so that when the shaft 61 and the arms 128 are rocked, the levers 125 are disengaged from the ratchets 126. 1

The means for shifting the shaft 61 to prepare the machine for total printing is shown in Figs. 3 and 4, and will now be described. A lock 131 having any desired construction, is rigidly mounted on the right hand side frame of the n1achine,-and a ratchet segment 132 secured to the key barrel 133, carries a pin 134pr0jecting into a slot 135 formed in a lever 136 loosely mounted a 137 on the right hand side 1 frame of the machine. The rearwardly and downwardly extending arm of the lever 136 is pivotally connectedv tojthe upper-endof a link 1237 which, at its lower end, is pivotally connected to a-lever 138 also pivotally mounted on the right hand side frame of the machine. The link 13'? intermediate its ends has a projecting arm .1381 provided with a recess into which projects a knob 139 formed on the right hand side arm of a yoke 140 loosely mounted on the shaft 61. The left hand side arm of the yoke 140 is provided with a slot 141 concentric with the shaft 61 and a pin 142 projecting from the right hand side frame of the machine projects through the slot. The yoke 140 carries roller 143 projecting into a cam groove 144 formed in the periphery of a segment 145 rigidly mounted on the shaft 61 within the yoke. I

When a key is inserted in the key barrel 133 and given one-half rotation in a. clockwise direction. (Fig. 3), the movement of the pin 134 in the slot 135 rocks the lever cam groove 144 tends 186 counter-clockwise, thereby elevating the link 137. The elevation of this link rocks the oke 140 cotmter-cloclnvise. The cam groove 144 in the segment 145 is so shaped that when the yoke 140 is rocked, as above described, movement of the roller n the cam. groove 144, shifts the shaft 61 towards the left to move the broad coupling pinions 59 into positionlo be rocked into mesh with the corresponchng pairs or gears 55 and 96. \Vhen the yoke 140 is rocked, movement of the roller 143 in the I to shift the yoke towards the right on the shaft 61, but such shifting movement of the yoke is prevented by thehead of the pin 142 which propels from the frame of the machine through the slot 141 in the yoke. After a total has been printed, the above described mechanism is restored to normal position by turning the. key in the key barrel counter-clockwise (Fig. 3) one-half rotation to normal post tion.

It is usual in the art to provide a number of totalizer elements which are of higher orders and for which no banks of amount keys are provided, these additional totaliz er elements being operated by the transfer mechanism when transfers from H e totalizer wheel of highest order a ipropriale to the bank of amount keys of highest order moves from its 9 to its 0 position. These additional totalizer elements usually control differential units similar to those controlled by the banks of amount keys in total print Ling operations sothat the amount standing on these higher order totalizer wheels is transferred to additional type wheels. In the present invention, instead of providing additional totaliZer elements whose amounts are transferred to additional type wheels in total. printing operations, the totalizer wheel of highest denomination transfers directly to additional type wheels which, in the present form or embodiment, do not print upon the detail strip or check strip during adding operations.

The above mentioned additional type carriers are in the form of type wheels 146 (Figs. 10 to 13, inclusive) positioned to retate on a sleeve 147 surrounding a stud 148 mounted in the left hand side frame of the machine. Loosely mounted on the stud 148 is a yoke frame 149 carrying a pivoted pawl 150 11 and 14) provided with operating tines cooperating with the ratchet wheels 152 fast to the type wheels 146. The construction of this operating means for the type wheels well understood andv known in the art, one being added on the lower order type wheel 146 each time the yoke frame 149 is oscillated about the stud 148. When said lowest order wheel 146 passes from 9 to 0 the graduated pawl 150 causes 1 to be added into the next higher arm 160 of the left hand side frame of the machine. The. arm 158 also carries a roller 161 which projects into a cam groove formed in the face of a disk 162 rigidly mounted on the left hand end of a sleeve 163 mounted to rotate about the shaft The left hand end of the sleeve 52 of the totalizer disk 54 of highest order has a ten'on 164 (Fig. 10)

engaging a recessin the right hand end of the sleeve 163, the sleeve 163 and the sleeve for the totalizer wheel of highest order being connected together in this manner so that the rotation of this totalizer wheel. is imparted to the disk 162. he cam groove in the disk 162 is so constructed that, as the totalizer disk of highest order passes from its 9 to its 0 position, the arm 156 is rocked, first counter-clockwise (Fig. 11) and then clockwise to normal position. This movement of the arm 158 oscillates the yoke frame 149 to effect transfers from the totalizer wheel, of highest order to the printing wheels 146.

In the Cleal and Reinhard patent above mentioned, the printing segment for printing characters designating the classes of transactions is immediately adjacent the highest order amount type segment. As the type wheels 146 in the present invention print the amounts in the denominations of higher order than those of the type segments 71., the segment 168 (Figs. 10 and 17) for printing characters designating the classes of transactions is positioned to the left of the units type segment 71. This type segment 168 is connected by a bar 169 to a collar 170 rigidly mounted on the outermost sleeve which is differentially positioned by' the bank of transaction, keys (not shown) through a segment gear (not shown) which meshes with a gear 172 fast on this outermost sleeve, as is well known in the art.

As the items entered in the machine are set up only on the amount type segments 71, and as the totals are set up on the amount segments 71 and the additional type wheels 146, it is desirable to print only from the type segments 71 in adding operations, and from these type segments and the additional type wheels 146 in the total printing operations. In order to prevent the additional type wheels 146 from printing on the check and the detail strip in adding operations, the platen is cut away from its circular periphery to the line 174 (Figs. 10 and 16) so that when the frame 77 carrying the platens is elevated, the platen does not engage the detail strip and therefore, the latter is not pressed into contact with the type wheels 146. WVhen a total is to be printed, however, the shaft upon which the platens 74 and 7 5 are rigidly mounted, is given one-quarter rotation preliminarily to the operation of the machine so that when the frame 77 is raised during the operation of the machine, the circular periphery of the platen 75 engages the detail strip to carry the latter against the additional type wheels 146 and thereby effect printing impressions. For the purpose of rocking the shaft 80, an arm is rigidly mounted on the shaft and near its free end carries a roller 176 projecting into a slot formed in the lower end of a link 177 which, at its upper end, is pivotally mounted on a segment gear 178 fast on the shaft At its right hand end, the shaft 53 rigidly carries a disk 180 (Fig. 3) having teeth 181 engaging a curved set of teeth 182 formed on the forward edge of the link 137. lVhen the link 137 is raised, as above described, the shaft 53 is rocked counter-clockwise (Figs. 3 and 16) through the intermeshing teeth 181 and 182, thereby rocking the segment gear 178 which, through the link 177 and the arm 175, rocks the shaft 80, as above stated.

lVhen the mechanism shown. in Figure 3 for controlling the machine for total printing operations is manually restored to normal position, the additional type wheels 146 are restored to their Zero positions. For the purpose of turning these type wheels to their Zero positions, the segment gear 178 meshes with a pinion 185 (Figs. 12, 15, and 16) fast on the sleeve 147 upon which are loosely mounted the type wheels 146. The type wheels, as shown in Figure 13, carry spring-pressed pawls 186, the ends of which rest on the sleeve 147. The sleeve 147 has a. longitudinal groove 187 which, when the sleeve 147 is rotated clockwise (Fig. 13) by the return movement of the segment gear 178 to normal position, engages the ends of the pawls 186 in whatever positions the wheels are standing and restores the wheels to their zero positions as is well known in the art. When the segment gear 178 is rocked clockwise, as viewed in Figure 15, when the machine is prepared for total printing operations, the sleeve 147 is rotated counter-clockwise, as viewed in Figures 13 and 15, and. during such rotation, the groove 1S7 moves idly past the pawls 186. When the segment gear 178, however, is rocked in the reverse direct-ion after a total printing operation has been accomplished, the sleeve 148 is rocked in reverse direction whereby the type wheels are restored to their zero positions, as above described.

As the differential mechanism is controlled by the totalizing disks 54 during total taking operations, it is necessary that none of the amount keys be depressed and therefore, the following described means is employed to lock the keys against depression when the machine is prepared to print a total. This means comprises key lockout bars 190 (Fig. 3), there being one bar for each bank of keys. The bars are slidably mounted at their upper and lower ends, and are therefore, at the upper ends provided with slots 191 through which pins on the key frames project, and at their lower" ends, with. slots 192 through which a cross rod 193 projects. The bars 190 at their lower ends carry pins 194 which contact arms 195 fast on a shaft 196. Fast on the shaft 196 is a lever 197, which may be operated at any time before the machine is operated, to rock the shaft 196 counter-clockwise (F 1 and 3) and, through pins 203 011 the shaft co-operating with pins 204 on the latch plates 17, draw the latter forwardly to effect the release of depressed amount keys, as is well known in the art. Springs (not shown) serve normally to retain the lever 197 and arms 19:") in the positions shown in Figure \Vhen the link 137 is elevated to prepare the machine for a total printing operation, a prong 198 on the lever 188 en gages the rearwardly extending arm 199 of the lever 197, thereby rocking the lever, the shaft 196, and the arms 195 clockwise. This movement of the arms 195 through their contact with the pins 194, elevates the key lockout bars 190 to carry the recesses 200, normally under the pins 201 on the keys, from under the pins" thereby lockingthe keys against depression.

It can be seen that if a key has been depressed, its pm 201 is in one of the recesses 200 and the bar 190 cannot be elevated, and therefore, the machine cannot be prepared for a total printing operation until after the lever 197 has been operatedto effect release of the key.- lVhen the link 137 is moved downwardly to normal position after a total printing operation, a prong 202 of the lever 138 engages the underside of the arm 199 of the lever 197 to insurethe re.-

turn of this lever, the shaft 196 and the arms 195, to normal positions.

As before stated, when the aetuatingiseg ments 40 are moved to their zero positions at the beginning of the operation of the machine, the projections 35 on the latch plates 17 (F which have not been moved. rearwardly, engage the pins 41 on the latches 38 and disconnect the segments 40 from their driving segments 86. In order to permit operation of all of the plates 17 for the banks of amount keys when the machine is prepared for printing a total, the detents 21 (Fig. 3) are operated, whereupon the springslS operate the latch plates 17 so that the projections 35 on the latch plates do not ei'igage the pins 41 on the latches 38, the latches in such operations being controlled by the registering disks, as above described. To operate the detents 21, each detent has a pin 205 contacting the upper edge of a toe 200 formed on the lower end of the corresponding lockout bar 190. When the lockout bars 190 are elevated preliminarily to a total printing operation of the machine, as above described, their toes 206 operate the detents 21, whereupon the latch plates 17 are drawn rearwardly by their springs 18, to permit the latches 38 to couple the driving segments 30 and the actuating segments 40. Operation of the detents 21 in this manner, through the engagement of their studs 22 with the arms 23, operates the shaft 99 and the arm 20 to move the arm 20 out of the recess 27 in the disk 28 and permit operation of the machine.

The following described device is employed to compel a complete one-half rotation of the lock barrel 133 (Fig. 3) to prepare the machine for total printing operations after the lock barrel has been partially turned. A lever 209, (Fig. 3) which is pivotally mounted at 208 on the right hand side frame of the machine, at its rear end has a nose 211 engaging under a hook 212 on an arm 213 of a lever'215 pivoted at 216 to the side frame of the machine. A spring 218 is connected at its upper end to the lever 209, and at its lower end to an arm 217 of the lever 215, the spring normally serving to retain the levers 209 and 215 in the positions shown in Figure 3. The forward end of the arm 217 engages the teeth of ratchet segn'ient 132 so that when clockwise movement of the ratchet segment is begun, the arm 217 prevents its return movement to normal position. Furthermore, after the ratchet segment has been given its one-half rotation the machine must first be operated before the ratchet segment can be returned to normal position. During the operation of the machine, the arm 217 of the lever 215 is disengaged from the ratchetscgment. A disk'220 fast on the shaft 29 carries a stud 221 which, near the very end of the operation of the machine, engages the free end of the arm 223 of the lever 2 15 thereby rocking the lever 215 countor-clockwise. When the lever 215 is rocked in this manner, the hook 212 on. i arm .213 is moved from above the nose 211 on the lever 209 and the spring 213 rocks the lever 209 so that its nose 211 is moved within the hook 212 and latches the lever 215 in its moved. position, wherein its arm 217 is disengaged from the ratchet segment. Near the end of the counter-clockwise movement of the ratchet segment 132 when the ratchet segment is moved back to normal position after the machine has been operated, a pin 224 on the ratchet segment engages an inclined edge225 on the lever 209, thereby rocking the latter to its normal position to permit the spring 218 to restore the lever 215 to normal position.

Having described in detail the construction and operation of the various parts of the present invention, a resume of its operation will now be given In adding operations the keys are depressed in accordance with the amount of the transaction and upon operation of the machine, the depressed keys arrest the latches 38 to disconnect the actuating segments 40 from their driving segments 36. Before the actuating segments are moved differentially out of zero positions the cam (37 (Fig. 2) moves the broad coupling pinions 59 (Figs. 1 and 5) into mesh with the corresponding pairs of gears 51 and 55 so that the differential movements of the actuating segments is imparted to thetotalizer disks 54, through the gears 45, 49, 51, 55, and pinions 59.

The movements of the actuating segments are imparted to the type segments 71, and while these type segments are in their moved positions, the frame 77 is operated so that the platen 74 carries the check and the detail strip against the printing line of the type segments to take printing impressions. lVhen the totalizer disk 54 of the highest order (Fig. 10) passes from its 9 to its 0 position, the cam 162 (Fig. 11), through the arm 158, operates the operating frame 149 and pawl 150 to add one on the lowest order of the additional type wheels 146.

lVhen a total is to be printed, the key barrel 133 (Fig. 3) and the ratchet 132 are given one-half of a rotation and through the lever 136, elevate the link 137. This movement of the link 137 rocks the yoke 140 which, in turn, shifts the shaft (31 towards the left through the movement of the roller 143 in the cam groove 144 formed in the segment 145 fast on the shaft. During the operation of the machine when the shaft 61 is rocked. by the cam 67, the pinions 59, having been shifted with the shaft, are moved into engagement with the corresponding pairs of gears 55 and 96 so that the totalizer disks are rotated backwardly. hen the pinions 59 are rocked, their hubs 108 (Figs. 5 and 6) engage and move the levers 105 rearwardly to carry the shoulders 111 on the levers into the paths of movement of the pins 110 on the totalizer disks 54. lVhen a totalizer disk approaches its zero position, its pin 110 contacts the shoulder 111 on the lever 105, thereby rocking the latter about the shaft 61 and the corresponding arm 100 about the shaft 99 to carry the projection 113 on the arm 100 into the path of one of the shoulders 114 on the plate 115 carried by the actuating segment. Engagement of the shoulder 114 with the projection 118 arrests the plate 115 and permits a slight additional movement of the actuating segment, the lower end of the plate 115 striking the pawl 42 to operate the latch 38 and thereby effect disconnection of the actuating segment and driving segment.

The differential movement of the actuating segments 40 in total taking operations is imparted to the type segments 71 in the same. manner as in adding operations. lVhen the link 137 is raised (Fig. 3), the shaft 53 is rocked through the intermeshing teeth 181 and 182, and through the segment gear 17 8 (F 16), the link 177 and the arm 175, the platens 74 and 75 are rotated so that when the frame 77 is operated during an operation of the machine the platen 75 car ries the detail strip against the additional type carriers 146. Thus the complete total is printed, partly from the type segments 71, and partly from the type carriers or wheels 146.

After the machine has been operated to take a total, the hey barrel 133 and the mechanism operated thereby are restored to normal positions. Movement of the segment gear 178 to normal position, through the pinion 185, rotates the sleeve 147 carrying the additional type wheels, and the sleeve, through the co-operation of its groove 187 with the pawls 186, restores these type wheels to their zero positions.
