SPECIFICATION forming part of Letters Patent No. 767,429, dated August 16, 1904.

Application filed .pril 15, 1903. gerial No. 152,735. (No model.)

T0 all whom, it may concern:

Be it known that LJAMES OPPENHEIM, a citizen of the United States, and a resident of the .writing machines to employ a series of column-stops either on a fixed portion of the machine or on the carriage and with which one or more arresting-stops cooperate. In such machines when the stops are brought into cooperative relation and the carriage is free to travel the arresting-stop necessarily engages the first of a series of column-stops (supposing the carriage to be at the extreme right) and thereafter engages successively the remaining column-stops. In certain classes of type-writing work in which it is desired to employ the number of column-field stops for defining a plurality of columnar fields upon the sheet to be printed it often happens that in certain of the lines of writing no entry is required in the first or, perhaps, in several of the first series of columnar fields, the entry or entries being made only in the last one or more of the predetermined columnar fields. Usuallytabulating mechanisms heretofore employed have been subject to the objection that under all conditions the carriage when released from its escapement was necessarily arrested at the first and at each succeeding column-stop until it finally reached the stop at which the desired entry was to be made.

One of the objects of my present invention is to overcome these difficulties and to provide means whereby a carriage may be arrested at any of a number of predetermined columnar positions without being first checked or arrested by other column-stops.

It has likewise been customary heretofore to provide type-writing machines with socalled ordinary tabulating or columnstop mechanism wherein the carriage is arrested at the proper column and at a point where the printing-point is at a position corresponding to, say, the units position in the column of figures to be written within the columnar field. Again, the machines have heretofore been provided with so-called denominational-stop mechanism wherein the carriage is arrested so as to bring the printing-point to the proper denominational position in the column of figures within the columnar field at which the carriage is arrested.

A further object of my invention is to provide both characters of tabulating mechanisms above referred to and to provide simple and efi icient means whereby either the column-stop mechanism or the denominationalstop mechanism, or both, may be brought into operation.

To theabove and other ends, which will hereinafter appear, my invention consists in the features of construction, arrangements of parts, and combinations of devices to be hereinafter described, and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a vertical front-to-rear central sectional view of one form of type-writing machine embodying my invention. Fig. 2 is a plan view of the same with parts broken away. Fig. 3 is a fragmentary view which corresponds to Fig. 1, except that in Fig. l a normal disposition of the parts is shown, whereas Fig. 3 represents one of the tabulating-keys (shown in full lines) depressed and another (shown in dotted lines) pushed longitudinally toward the rear of the machine. Fig. 4 is a detail perspective view of the tabulatingmechanism. Fig. 5 is a rear elevation of the various sets of stops carried by the carriage with some of the parts broken away. Fig. 6 is a transverse sectional view of the same, the section being taken on the line w m of Fig. 5. Fig. 7 is a detail perspective view of one of the stepped denominational stops.

elevation of the actuating-bar through which the tabulating-key levers extend, the levers Fig. 8 is a detail front being shown in section. Fig. 9 is a detail front elevation of the arresting-bar for the tabulating-key levers.

In the various views parts have been omitted and parts broken away in order to more clearly illustrate other features of the construction.

l have shown my invention applied to a No. 6 Remington type-writing machine, though it should be understood. that the invention or any of the various features thereof may be applied to other characters of type-writing machines.

The frame 1 of the machine is surmounted by a top plate 2, that has upwardly-extending lugs 3', to which a traverse-rod 4: is fixed. The carriage 5 carries antifriction-rollers 6, which bear upon the traverse-rod and support and guide the carriage in its movement from side to side of the machine. The carriage is also guided by a traverse-rod '7, with which an arm 8, that is connected to the carriage, cooperates. A platen 9 is supported by the carriage or its platen-frame and is adapted to revolve therein. The forward portion of the carriage carries a roller 10. that is supported upon a shift rail or rod 11, that may be actuated by the usual or any suitable means. A carriage feed-rack 12 is secured to the forward ends of curved arms 12, that bridge the traverse-rod. and are pivoted to the carriage at 13. Extending downwardly and rearwardl y from the arms 12 and beyond the pivots thereof are arms 14:, which carrya bar 15, that extends throughout or substantially throughout the length of the feed rack and carriage. The feed-rack 12 meshes with the feed-pinion 16, that is fixed upon the forward end of a shaft adapted to rotate in a bearing 17, which is secured to the top plate of the machine. The rear end of this shaft is operatively connected to an escapement-wheel 18, with which the feed-dogs 19 and 20 cooperate. The feeddogs are carried in the usual manner upon a dog-rocker 21, the rock-shaft 22 of which is mounted in suitable hearings in the frame of the machine and has a forwardly-extending crank-arm 23, to which a transverse bar 2& is secured. Connected to each end of the transverse bar is a depending link 25, that is connected at its lower end to a universal bar 26, which extendsbeneath the series of key-levers 27, fulcrumed at 28 and provided with the usual finger-keys 29 at their forward ends. A restoring-spring 30 is connected at one end to the rock-shaft and at its other end 31 to a fixed bracket-plate that supports the bearings for the rock-shaft 22 of the dog-rocker. Each of the key-levers is connected to a link 32, which in turn is pivoted at its upper end 33 to a type-bar 34. Extending beneath the series of key-levers and out of the paths of movements thereof are a series of tabulatorkey levers 35, each of which is slotted at 36 and has a fixed pivot-rod 37, that extends through a slotted portion thereof and is secured at its ends at the sides of the machine. These tabulating-key levers are each connected to one end of a contractile spring 38, the opposite end of each spring being secured at 39 to an arresting-barLO, which is fixed at its ends to the sides of the framing of the machine and has secured thereto a series of restoring-springs 41, each of which bears on a tabulating-key lever forward of its pivot in order to restore its key-lever to the normal position considered with relation to the pivotal movement thereof. From the foregoing description it will be seen that each of the tabulating-key levers is capable of moving in two directions-that is to say, it is capable of a pivotal movement around the fixed pivot 37 and is likewise capable of a sliding movement fore and aft of the machine by reason of the slot 36 therein. 38 of each key-lever tends to restore it to its normal position considered with relation to its longitudinal movement or the movement thereof fore and aft of the machine. The various key-levers project through openings &2 in a so-called controlling-bar 43 and each of these levers is provided with a finger-key 44: at the outer end thereof, which is of suflicient size to prevent the key or head from passing through the associated opening 42 in the bar, so that when a key is moved toward the rear of the machine it will take up the bar i3 near the end of its movement and cause the bar to move with it.

Each finger-key has two faces, one at an angle to the other. Thus each key-lever has an inclined face 45 and a vertical face 4E6, the inclined faces bearing one set of indices, whereas the vertical faces bear another set of indices, and the bar 43 has an inclined upper edge 43, that bears a third set of indices, one at each tabulating-key, all for purposes which will hereinafter.appear.

Various tabulating-key levers are received within guiding-slots 47 in the fixed stop-bar 40. These slots in the stop-bar L0 are at various depths, as indicated in Fig. 9, so that different extents of depression are afforded different key-levers in their pivotal movements. Thus, for instance, nine tabulating-key levers are shown, and the key-lever at the left hand in Fig. 9 has the greatest extent of depression by reason of the fact that the deepest slot 47 is provided for this key-lever. The depth of the slots gradually decreases from left to right until the two right-hand tabulating-keys 35 are reached, where the bottom walls of the slots 47 are coextensive with the bottoms of the key-levers when the latter are in their normal positions, so that these two levers, which bear the numerals 8 ant 9 on the inclined faces 45, normally rest at the bottoms of their respective slots of the stop-bar 40, and no pivotal movement therefore can be given to these key-levers, merely a reciprocating move- The contractile spring ment fore and aft of the machine. The socalled controlling-bar 43 has depressions 48, which correspond to the slots 47 in the stopbar, and certain of the tabulating-key levers as 35*, 35, and 35, for instanceare made of greater width, considered vertically, than the others. The object of this arrangement is to take up the controlling-bar 43 at a given period during the depression of any of the tabulatingkeys, notwithstanding the fact that the various tabulating-keys have different extents of depression in order that the carriage-releasing mechanism, which is controlled by the controlling-bar 43, may be released at a predetermined time relatively to the completion of the depression of any of the various tabulatingkeys, as will hereinafter more clearly appear. The controlling-bar 43 is secured near its ends to bars or levers 49, that correspond substantially to the tabulating-key leversthat is to say, each of the bars 49 has a slot 50, through which the pivot-rod 37 projects and has a contractile spring 51, that tends to move it toward the front of the machine, whereas a leafspring 52 restores the bar or lever toits normal position considered with relation to the pivotal movement thereof. Each of these bars or levers 49 is likewise received in a guidingslot 53 in the stop-bar 40. The sole purpose, however, of the slots 53 for these levers is to provide a guiding-slot for the levers in their reciprocating and pivotal movements. The rear end portions of these levers 49 are connected by a rod 49, so as to constitute, with the bar 43, a rectangular frame that is movable in two directions, one a pivotal movement around the pivot-rod 37 and the other a reciprocating or sliding movement fore and aft of the machine. The rear ends of the levers 49 are bent upwardly at 54, and bearing pins or screws 55 rest on the upper edges of the upwardly-bent portions. The bearing pins or screws 55 are carried by and extend laterally from bell-cranks 56, which are secured to a rock-shaft 5T, pivoted in the base of the frame 1 of the machine. The upwardly-extending arms of these bell-crank levers are united by a bar 58, that extends in front of and adjacent to a depending arm 59, which projects from a rock-shaft 60, pivoted in a fixed bracket 61, and which carries a crankarm 62, that extends upwardly and then forwardly, as indicated at 63, and has the free end thereof extending normally adjacent to the bar 15, that is connected to the carriage feed-rack 12.

From the foregoing description it .will be understood that a depression of any of the depressible tabulating-keys will cause the controlling-bar 43 to be depressed during the last portion of the stroke of said key, thereby elevating the rear end of the frame, of which the bar 43 forms a part, thus swinging the bell-crank levers 56 on their pivotal center. The effect of this movement is to move the depending arm 59 rearward'ly through the bar 58, thus swinging the upper arm 63 forwardly against the bar 15 to effect an elevation of the feed-rack, thus releasing the carriage from its escapement mechanism. l/Vhen the tabulating-key is released, the parts will be restored to their normal positions by a contractile spring 64, which is connected at one end to the depending arm 59 and at the opposite end to a fixed portion of the machine, as indicated at 65, and this spring in effecting a forward movement of the arm 59 causes it to move the bar 58 in the same direction, thus swinging the carriage-releasing frame on its pivot 37 so as to elevate the bar 43 of said frame to the normal position, whereas the spring 41 of the depressed tabulating-key is effective to restore it to the normal position.

The depending arm 59 likewise carries at the lower end thereof a transversely-extending bar 66, with which the hook-like ends 67 of the levers or bars 49 are adapted to cooperate. Thus the pushing movement of any of the tabulating-keys toward the rear of the machine will bring it into contact with the controlling-bar 43 during the latter portion of the stroke of the key, thereby moving the frame, of which the bar 43 forms a part, in the same direction. This movement is effective to bring the hook-like portions or ends 67 of the bars 49 of the frame into contact with the transversely-extending bar '66 and to move it rearwardly, thereby swinging the arm 63 forwardly to effect a release of the carriage from its escapement mechanism in the manner hereinbefore described. It will be understood that the arm 63 is adapted to effect a release of the carriage irrespective of the position to which the carriage may have traveled, inasmuch as the bar 15, with which the arm 63 cooperates, extends substantially throughout the length of'the carriage.

I have described the means whereby either a pivotal movement or a longitudinal movement of any of the tabulating-keys is effective to release the carriage at or near the end of the stroke of said key, and I will now describe how the same movements are effective to interpose either of two arresting-stops in the path of a cooperating stop or stops on the carriage. Extending transversely across and above the various tabulating-key levers is a bar 68, that constitutes a part of a frame, the upwardly-extending side members 69 of which are received in openings in brackets 7 O, secured to the frame of the machine, so that the frame of which the members 68 and 69' form parts is guided in its vertical movements. A coiled spring 71 surrounds each of the upright members 69 and bears at one end against a collar 72 on said member and at its opposite end against the associated bracket 70. The

upper end of each member 69 is provided with a collar 7 3, which in the normal position of the frame rests upon the upper face of its associated braeketTO. A. cross-bar 7 1 is connccted to the upper ends of the upright members 69 and carries an upwardly-extending plunger-arrcsting stop 75, which is received in and projects through a guiding-opening in a cross-bar 76 of a bracket 76, secured to the top plate of the machine. of any of the depressible tabulating-key levers the rear end thereof is brought into contact with the cross-bar (58, thereby elevating the frame of which it constitutes a part, thus raising the stop and interposing it in the path of one of the cooperating column steps or shoulders '77, carried by the carriage. These steps or shoulders '77 are in the nature of graduated or step-shaped stops that are formed upon a bar 78, the upper edge of which is secured to a stop-bar 79 or which is made integral with the bar 79. These shoulders or stops 77 are preferably arranged at ten letter-space distances apart and correspond to the seventy letter-spaces on the scale of the machine divided into divisions of ten. It has heretofore been explained that each of the first seven tabulating-keys counting from the right and bearing the numerals 10 to 70 have different extents of dip, so that a different extent of' movement will be given to the stop '75 at the depression of each of said keys, the greatest extent of dip being afforded the key bearing the numeral 10 and the least extent of dip being afforded the numeral 70. 1f, therefore, the operator depresses the key bearing the numeral 10, the stop will be elevated to its greatest extent, thereby bringing it into the path of the highest of the step-shaped stops '77 on the carriage, and the carriage will be arrested at the tenth letter-space distance on the scale, assuming that the carriage is at the extreme right when the talmlating-key is depressed. If, on the other hand, the seventh key or that marked with the numeral 7O is depressed, the least extent of vertical movement will be given to the stop 75, and it will be brought into the path of the lowest stop 77 on the carriage, thereby permitting a free run of the carriage until the last or lowest of the series of stepshaped stops 77 is reached, and the carriage will be arrested at the point 7O on p the scale and so that the depression of any of the intermediate keys will arrest the carriage at the proper point indicated by the numeral on the end. of the key depressed.

The stop-bar 79, hereinbefore referred to, is divided into seven series of step-shaped steps 80, that are located at letter-space distances apart, and the stops of each series, there being nine in each series, are progressively arranged at greater distances fore and aft of the machine. Cooperating with the stops 80 is a plunger-arresting stop 81, carried by a slide 82, that is adapted to move in abearing 83, carried by the bracket 76, which is se- 1 On the depression cured to the top plate of the machine. One side of the bearing 83 is slotted at 84 to receive a pin 85, which projects from the slide 82 through the slot and is received within a slotted opening 86 in the end of an arm 87, guided in the slotted portion 88 of the bracket 7 6, the arm 87 projecting from a rock-shaft 89, pivoted in the fixed brackets 61. Depending from the rockshaft 89 is an arm 90, that carries a transversely-extending bar 91 at its lower end, which bar extends beneath the various tabulating-key levers. A coiled spring 92 surrounds the rock-shaft 89 and is secured at one end 98 to the depending arm 90, wherethe other end of said spring is secured to one of the brackets 61, so that the tension of said spring is exerted to restore the rock-shaft and the parts connected thereto to the normal positions. (IllustratedinFigs. land 5.) Each of the nine tabulating-keys carries a depending abutment 941, that is adapted to contact with the transverse bar or rod 91 when the key-lever which carries it is moved toward the rear of the machine, thus moving said bar toward the rear to effect a forward move ment of the arm 87 and the stop 81, which is connected thereto. The depending abutments 91 on the various tabulating-key levers are arranged at progressively greater distances from the rear ends of the lever and toward the front of the machine, beginning with the left-hand tabulating-key and ending with the right-hand tabulating-key. hile the various tabulating-keys receive a given extent of reciprocating movement fore and aft of the machine, the bar 91 and the parts controlled thereby will receive different extents of movement by reason of the different disposition of' the various abutments 9-11 on the different tabulating-keys. Thus if the lefthand tabulating key bearing the numeral. 1 is pushed toward the rear of the machine it will cause the abutment 94.. thereon to force the bar 91 toward the rear, giving the longest throw thereto, thereby bringing the movable stop 81 into the path of the first stop 80 of one series or that stop of the series which is nearest the front of the machine, thus permitting the carriage to move one letter-space distance. If, on the other hand, the right-hand key bearing the numeral 9 is pushed toward the rear of the machine, then the bar 81 will receive its shortest extent of rearward movement and will interpose the stop 81 in the path of the rearmost stop 80 of one series, thereby permitting the carriage to travel nine letterspace distances. It will therefore be seen that the carriage may be arrested at any one of nine letter-space distances, determined by which key of the nine is pushed toward the rear of the machine. It has heretofore been explained that the pushing in of any of the tabulatingkeys in the manner described will bring the head thereof into contact with the bar 13, thereby moving the frame, of which the bar 13 constitutes a part, toward the rear of the machine. The effect of this movement is to move the bar 66 rearwardly, thereby releasing the carriage from its escapement mechanism, as heretofore explained. This latter movement, however, is not effected until the latter part of the reciprocating or rearward movement of any key and does not take place until the stop 81 has been or is just about to be interposed in the path of a cooperating stop 80 on the carriage.

The stop-bar 79 is provided at its ends with depending ears or lugs 95, which are apertured for the reception of headed screw-pivots 96, the stems of which extend through openings therein and into threaded openings in upwardly-projecting lugs 97, that extend from the carriage. The stems of these screw-pivots likewise extend through openings in lugs or ears 98, which project laterally from the ends of a rack-bar 99, the teeth of which are situated a letter-space distance apart and correspond to the carriage-scale. The lugs 98 carry laterally-extending pins 100, which project upon opposite sides of the stop-bar 79, as indicated in Figs. 5 and 6, so that the stop-bar 79, with its stop-bar 7 8 and rack 99, are locked to turn together on the pivots 96. The lugs 98 likewise carry spring-catches 101, each of which has an engaging projection 102, that is adapted to engage under the flange 103 of the transversely-extending rear carriage-rail, as illustrated in Fig. 6, when the parts are turned on their pivots 96 to the position indicated in this figure for a purpose which will hereinafter appear.

From an examination of Fig. 7 it will be seen that a stop-carrier 10 1 has graduations or step-shaped stops 105 thereon and that from the base 106 of the carrier project teeth or fingers 107, which are three in number. Each of these teeth or fingers has a hook-like portion 108, and secured to one edge of the base 106 are spring-catches 109, each of which terminates in a curved or projecting portion 110. The construction of each of these stop-carriers, or stops, as they may be termed, is such that the teeth 107 may be seated within spaces between the teeth 111 on the rackbar 99, and the hook-like portions of the teeth 107 will engage the body of the rack-bar, as illustrated in Figs. 5 and 6. At this time the bent ends of the spring-catches 109 will engage in a depressed portion 112 in the body of the rack-bar, and thus maintain the stop or stop-carrier in locking engagement with its rack. This construction is such that the carrier may be readily connected to or disconnected from the rack-bar and adjusted at any desirable point along the rack. It will be understood that any suitable number of these stopcarriers may be employed on the rack 99 and that when in position the stops 105 will extend in the same general direction as the stops 77 on the bar 78, as illustrated in Fig. 5, the

planes of the carriers or body portions of said stops being parallel, as indicated in Fig. 6. When the stops or stop-carriers 10 1 are in position, there will be three groups or stops carried by the carriageviz., the stops 77, the stops 80, and the stops 105all of which are connected together and are secured to virtuall y constitute a frame that is pivoted to the carriage and is adapted to be swung and maintained either in the position represented in Fig. 1 or in the position shown in Fig. 6. W hen the parts are in the position shown in Fig. 1, the stops 105 are moved to a position where they are inoperative for any purpose, and at this time the stops 77 and 80 are adapted to cooperate with the arresting-stop and 81, respectively. When, however, the pivoted frame is shifted to the position shown in Fig. 6, the stops 77 and become inoperative, being moved to a position where they can no longer cooperate with the stops 75 and 81. The stops 105, however, are at this time moved to a position where the stop 81 when moved forward will cooperate therewith.

In order to insure the proper movement of the tabulating-key levers, whether it be a reciprocating or a' pivotal movement, the rear end of each lever is received within a guide, the upright groove or guide 113, which guides the rear end of the lever. in its vertical movement, and the horizontal groove 01' guide 11 1 guiding the rear end of the lever in its horizontal or reciprocating movement. From an examination of Fig. 1, whichillustrates the parts in their normal positions, it will be seen that the rear end of each tabulating-key lever is normally disposed at the point of intersection of the two grooves 113 and 114 and at this time the key may be either depressed or moved toward the rear of the machine. If a key is depressed, the rear end of its lever will be immediately moved out of register with or away from the groove or guide 11 1, and the rear wall of the groove or guide 113 will prevent the key-lever from being pushed rearwardly until it again assumes the normal position. If, on the other hand, a key-lever is moved rearwardly from the normal position, the rear end is immediately carried beyond the groove 113, and the top wall of the groove 114 will prevent an upward movement of the rear end of the keylever and will consequently prevent a depression of its key. It will therefore be seen that means are provided to guide each key-lever and insure a proper movement thereof, whether it be a pivotal movement or a longitudinal reciprocating movement, once a keylever is started in either direction.

Each tabulating-key lever is limited in its rearward movement by a shoulder 115 thereon being brought into contact with a rear wall of its groove 113, which prevents further rearward movement of the lever, thus insuring uniform extent of rearward movement of all the tabulating-key levers, as heretofore stated.

Assuming that the parts are set, as represented in Fig. 1, so that the stops 77 and 80 are in the operative position and that the carriage is at the extreme rightand the operator wants to stop the carriage at the point 40 on the scale with the tabulating mechanism, it is merely necessary to depress the tabulating-key bearing the numeral 4:0, which is effective to move the stop into the path of the fourth stop 77 and to release the carriage, when it will travel to the left until the fourth stop 77 arrives at stop 75. The first, second, and third stops 77 at this time being at a higher elevation than that to which the stop has been moved will be out of its reach and will not be affected thereby, and the carriage will be arrested 'at 40 on the scale. Should the operator desire to arrest the carriage at 15, for instance, with the tabulating mechanism, it is merely necessary to depress the tabulating-key bearing the numeral e0, as previously described. After the carriage has traveled to and been arrested at 10 on the scale release the key andv push the 5 key rearwardly. The effect of this is to bring the stop 81 into the path of the fifth stop of the fourth series of nine each and at the same time to release the carriage and permit it to move five letter-space distances, or until the fifth stop 80 of the fourth series is brought into contact with the stop 81. The key-lever may then be released, and the parts will be restored to the normal posi tions by their several springs and the carriage positioned at 4:5 on the scale. It will therefore be seen that two separate arresting-stops are adapted to be moved to different extents by the same set of tabulating-keys, a move' ment of the keys in one direction moving one of the stops, whereas a movement of the keys in another direction actuates the other stop. Thus the stop 75 is projected to different extents into the path of the stop 77, which are situated ten letter-space distances apart, and the carriage may at once and by a single actuation of the one of the tabulating-keys be arrested at any of the divisions controlled by these stops. On the other hand, the stop 81 is projected to different extents into the paths of the stops 80 of any set thereof, each set being nine in number, so that the proper letterspace position within any division between the stops 77 maybe attained. 1f the point at which the carriageis to be arrested is at 10 or any multiple thereof up to (0, a single actuation or reciprocating movement of any of the talmlating-keys will effect the result, whereas if the carriage is to be arrested at a point other than 10 or any multiple thereof up to 70 then an actuation or reciprocation of one of the tabulating-keys is first required and then a subsequent depression thereof in order to arrest the carriage at the proper position.

While 1 have described that the rack-bar 78 has its stops 77 located at ten letter-space distances apart, it should be understood that the steps may be situated at greater or less intervals apart. It should likewise be understood that while have described the stopbar 79 as provided with seven series of stops 80, nine stops being provided in each series, the stop-bar may be otherwise provided and a fewer or greater number of series of such stops may be employed.

It will be understood that the screw-pivots 96 permit of the withdrawal or dismounting of the frame, of which the stop- bars 78 and 7 9 and. rack-bar 99 constitute parts, so that stop-bars of different characters may be employed or frames having stop-bars of different charactersmay be substituted one for another.

By pivoting the frame comprising the various stop-bars and rack 99 in the manner described am enabled, as heretofore described, to turn the frame to the position shown in Fig. 6 and to lock it in such position by the check-springs 101, thus maintaining the stops 7'7 and 80 out of the operative position and bringing the stops to a position where they are adapted to cooperate with the plunger or arresting-stop 81. This arrangement is such that one or more carriers 104 having graduations are provided, which may be adj usted to the desired positions along the rackbar 99, and a denominational tabulatingmechanism is thereby provided. The adjustment of the stop-carriers 104 regulates the columnar positions, and at the same time the step-shaped stops 105 afford an arresting of the carriage at different denominational positions, as determined by the extent of movement of the cooperating plunger stop 81. From an examination of Fig. 4 it will be seen that a set of indices are carried on the inclined face 43 of the bar 43, as heretofore described. These indices correspond with different denominational positionssuch as units, tens, hundreds, &c.*and commence at the third key from'the right and are situated adjacent to the tabulating-key levers with which they are associated. Thus the letter u designates the third key from the right, which corresponds to the units position, whereas the index t designates the next key to the left, which corresponds to the tens position, and the index h is adjacent to the next key to the left and indicates the hundreds position, and so on up to the seventh or millions key, adjacent to which is the index m, it being borne in mind that a rearward sliding i movement of the tabulating-keys will effect a forward movement of the stop 81 to different extents. It will be understood that the great- On the other hand, a rearward movement of the seventh key from the left, which is last of the depressible keys, projects the stop 81 into the path of the stop 105, which is farthest from the rack-bar, thereby arresting the carriage at the units position, (indicated by the index u,) so that an efficient denominational tabulator which is actuated in the ordinary manner is produced by merely locking the frame carrying the stop- bars 78 and 79 and rack 99 in the position shown in Fig. 6.

It will be seen that three separate sets of indices are provided for the tabulating-keys, one of which consists of the numerals 1 to 9 on the inclined faces 45 of the keys and which designate the nine positions to which the carriage may be moved within a division of thestops 77. The other set of indices consists of the numerals 10, 20, and so on up to '70, on the forward vertical faces of the first seven keys, counting from left to right, and which indicate the keys that control the arrest of the carriage for the seven divisions at ten letter-space distances apart and which is effected by the plunger-stop and the series of stops 77 when the key-levers are pushed toward the rear of the machine. The third set of indices consists of the marks uff t, h, 1t, 10t, ht, and m, ad acent to the first seven keys, counting from the left, and which indicate the denominational arrest of the carriage to any position from the units to millions by a single actuation of any of the tabulating-keys when the stops 105 are employed.

From theforegoing description it will be understood that the stops 77 constitute columnstops and that the stops 7 5, which cooperate therewith, constitute what may be termed a column arresting-stop, that the stops 80 and 105 constitute denominational stops, which enable the carriage to be arrested at the proper letter-space or denominational position within the column, and that the stop 81 cooperates with either the stops 80 or the stops 105 to arrest the carriage in such positions and may be termed a denominational arresting-stop,

that the stops 75 and 81 are actuated independ-v ently of each other by the same keys, a movement of a key-lever in one direction (a pivotal movement) actuating the stop 7 5, whereas a movement in another direction (a longitudinal movement toward the rear of the machine) effects an actuation of the stop 81, and that a movement of the keys in either direction automatically effects a release of the carriage, that the stop 77, each set of nine stops 80, and the stops 105 on the carrier 10% may in each instance be regarded as graduated stops or a set of graduated stops, that the guides 113 and 114: constitute, respectively, vertical and horizontal guides for the tabulating-key levers, and that when a lever is seated and starts to move in one guide it is prevented from moving in any direction other than that which is l permitted by the guide in which the lever is seated.

While I have shown and described with considerable particularity one form of construction embodying my invention, it should be understood that various changes may be made without departingfrom the spirit of my invention and that from certain aspects of my invention certain features may be employed without the others.
