TYPE-WRITING MACHINE.

Specification of Letters Patent.

Application filed August 6, 1909.

Patented Nov. 1, 1910. Serial No. 511,613.

To all whom it may concern:

Be it known that I, ANDREW WV. S'rnronn, a citizen of the United States, and resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful. Improvements in Type- Writing Machines, of which the following is a specification.

My invention relates more espec ally to tabulating mechanism for typewritingmachines and its object generally stated is to provide improved devices of the class specitied.

More specifically my invention has for one of its objects to provide improved denominational tabulating mechanism.

Another object is to provide improved column selecting mechanism and which may be employed with a comparatively large number of columns.

Another object is to provide key controlled devices which enable the same keys which are employed for denominational tabulating operations to be additionally employed for column selecting operations.

Another object is to combine denomlnational and column selecting mechanism in a much simplified and improved manner.

Other objects will hereinafter appear.

To the above ends my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

In the present instance my invention is shown as embodied in a front-strike typewriting machine, such parts of the machine as are not essential to a clear understanding of said invention being omitted. It is to be understood, however, that the invention may be adapted to styles of writing machines other than the front-strike machine shown.

In carrying out my invention in the present case, a plurality of column stops are adjusted on a stop bar on the traveling element or carriage to correspond with the columns of the tabular work in hand, and a set of key controlled denominational stop levers are supported on the frame of the machine. Ordinarily when one of the denominational keys is operated it will effect the release of the carriage and position the associate denominational stop in the path of the column stops so as to arrest the carriage when the first column stop thereon contacts with the actuated or projected denominational stop. In order to adapt the mechanism for column selecting work a slidable member is provided which is controlled by a key or key bar arranged in proximity to the row of denominational keys and extending lengthwise of said row, said key bar being adapted to control a slidable member which is operated to position certain stop devices so that they will be progressively advanced by cooperation with successive column stops. devices and the consequent arrest of the carriage is determined by the engagement of certain of said devices with one of the denominational stop levers. The particular stop lever which is moved into position for such engagement will depend on the column at which it is desired to arrest the carriage. When used for column selecting purposes the denominational levers are arrested before they have moved into the path of the column stops and serve as limiting means for the progressively moved column selecting stop devices, certain of said devices cooperating directly with the column stops. The key bar is held or otherwise maintained in the operated position as long as it is desired 'to employ the mechanism for column selecting purposes. After any particular column has been reached the key bar may be released and the denominational keys employed in the usual way to bring the carriage to any desired denominational position in that particular column.

Following is a detailed description of the construction and mode of operation of the exemplification of my invention herein illustrated.

In the accompanying drawings, Figure 1 is a top plan view of a front-strike typewriting machine embodying my invention, parts of the machine being omitted and parts broken away. Fig. 2 is a vertical longitudinal sectional view of the machine with parts omitted and parts broken away. Fig. 8 is a rear view partly in vertical section, showing details of my invention. Fig. 4 is a view corresponding to Fig. 3 but showing some of the parts in different relations and omitting other parts shown in said Fig. 3. Fig. 5 is a perspective view of the tabulator key system. Figs. 6 and 7 are views similar The extent of advance of said stop' to Fig. 3 but are drawn on an enlarged scale and show the parts in different stages of operation. Fig. 8 is a fragmentary seetional view corresponding to Fig. 3 and showing various parts of Fig. 1 on an enlarged scale. Fig. 9 is a side view of certain of the parts as they appear in Fig. 7. Fig. 10 is a sectional view taken on a plane represented by the dotted line m-m in Fig. 6 and looking in the direction of the arrows at said line.

Referring first to Figs. 1 and 2, the body 1- of the main frame is surmounted by a top plate 2 formed with a depression 3. Key levers 4 are fulcrumed at 5 in rear of the base of the main frame, each key lever being connected as by a link 6, a bell crank 7 and a second link 8 with a type bar 9 pivoted on a hanger 10 secured to a vertically disposed segmental support 11. Only one type bar is shown but it is to be understood that a complete set of type bars are provided, arranged in an arc of a circle on the segment 11, the type ends of said type. bars normally resting on a segmental type rest 12. The actuating mechanisms of the type bars are provided with restoring springs (not shown) and when each type bar is actuated it will cooperate with the front face of a cylindrical platen 13 rotatably supported on the end plates 14 of a traveling element, carrier or carriage which further comprises a slide bar 15 at the ends whereof rise the end plates 14. The front and rear faces of the slide bar are formed with longitudinally extending grooves which receive anti-friction balls 16, said balls also cooperating with fixed track ways 17 suitably secured at the front and rear sides of the depression 3. Levers 18 pivoted at 19 to the ends of the slide bar 15 support at their lower ends a feed rack 20, the upper ends of said levers cooperating with springs 21 which serve to constantly press the feed rack toward a feed pinion 22 and normally to maintain said feed rack in mesh with said pinion. The pinion 22 is secured to the upper end of a vertical shaft 23 which passes through the bottom of the depression 3, the lower end of said shaft bearing in a stationary bar or bracket 24. Near its lower end the shaft 23 carries a toothed carriage feeding or escapement wheel 25 with which cooperate feed dogs 26 mounted on a rocker 27 secured to a rock shaft 28 pivoted on an arm 29 projecting forward from the bracket 24. Arms 30 extend forward from the rock shaft and carry depending links 31 which support a universal bar 32 underlying the key levers. The carriage is constantly urged leftward by a spring drum 33 pivoted on a bracket 34 depending from the portion 3 of the top plate, said spring drum being connected with the carriage by a strap or cord 35.

It will be understood that when one of the .apart.

printing key levers 4 or the usual space bar or key is operated it will actuate the universal bar 32, causing the carriage feeding devices to cooperate to permit a letter space feed movement of the carriage under the pull of the main spring. It will further be understood that the carriage is or may be equipped with the usual or suitable paper feeding devices including a paper deflector or guide 36 and a feed roller 37 that the platenis or may be associated with suitable line spacing devices comprising a ratchet wheel 38, a pawl 39 and a hand-operated lever 40; and that suitable inking devices preferably comprising an ink ribbon and means for feeding and controlling it are employed although not shown herein.

The tabulating mechanismcomprises a stop bar 41 arranged in rear of the platen and extending lengthwise thereof, said stop bar being secured at its ends to the end plates 14. The front and rear faces of the stop bar are preferably notched as indicated at 42 to provide teeth a letter space distance Adjustably supported on the stop bar 41 are column steps 43 which are or may be plate-like in form and cut out to fit between the teeth of the stop bar 41. Each step plate 43 is provided at its rear with an extension or depending stop portion 44 which is the stop proper. A set of angular levers 45 are provided to cooperate with the column stops in different ways. The vertically disposed portions of said levers pass upward through an opening 46 in the top plate and terminate in stop portions 47. Said vertical portions extend downward parallel .with each other and pass between the key levers 4 and then gradually curve forward into the horizontal portions of said levers. The levers are fulcrumed through their horizontal portions on a rod 48 which extends transversely of the key levers below the same and is secured in the sides of the base. The forward end portions of the levers 45 are reduced as indicated at 49 and are received in holes in vertical key stems 50, said key stems being guided in openings in

stationary guide plates

51 and 52 and terminating at their upper ends in buttons or finger keys 53 which may be provided with suitable indicating marks on their upper surfaces. As shown in the drawings there are ten tabulating keys 53 and ten associate levers 45. The keys are arranged in a bank or row in rear of the regular keyboard and above the last row of said keyboard. Said keys 53 as herein shown are oblong and are spaced a convenient distance apart. From their points of connection with the key stems-5O the horizontal portions of the levers 45 extend rearward and at the same time incline inward toward the middle of the machine so that the rear or vertically disposed portions of the levers 45 lie comparatirely close together (see. Fig. The upper emls or stop portions 47 of the levers 45 are guided in slots 54 formed a letter space distance apart in a. guide plate 55 which is suitably secured to the rear portion of the top plate 2 over the opening 4-6. Normally the stop portions 4-7 are maintained at the rear ends of the slots M and below the plane of the stop portions 44. by springs 56, each spring being secured at one end to one of the levers -15 and at the other end to a stationary bracket 57.

It will be miderstood that when one of the keys 53 is depressed it will swing the associate lever 45 on its pivotand raise the stop portion 47 upward and. forward so that if the movement is not interfered with said stop portion will be brought into the path of the extensions or stops 4%, being thereby adapted to arrestthe carriage in a particular deiiominatioi'uil position.

Means are provided for automatically releasing the .arriage from its ste] .)-by-step feeding devices through the operation of the levers l5. Said means may comprise a retarding contrivance which consists in part of a casing 58 pivotally supported at 59 on a bracket ($0 depending from the depressed part 3 of the top plate. Retarding contrivances of any suitable character are arranged in the casing and are adapted to be operated from a shaft 61 which extends upward, hearing in a hub (39 integral with the casing 58. Said shaft carries outside the casing apinion 63 which normally lies in front of and out of mesh with the feed rack 20 but is adapted, when the casing 58 is swung rearward, to force said rack out of mesh with the feed pinion 22 and against the pressure of the springs 21, thus releasing the carriage and permitting it to run under control of the retarder. The means for swinging the casing and pinion (53 rearward comprise a link (34 pivotally connected at its upper end with the casing 58 forward of the pivots 59. Said link extends downward and is pivotally connected at its lower end with an arm or extension 65 extending rearward from the pivot rod 48 and integral with an arm 66 extending forward from said pivot rod. As shown in Fig. 5 the arm 66 lies at the right of the set of lovers 45. A similarly forwardly extending arm 67 is pivoted on the rod 48 at the left of the levers 45. The two

arms

66 and 67 are connected by a release bar 68 which underlies the levers 45 near their forward ends and is adapted to be operated when any one of said levers is depressed so as to raise the link 64 and cause the pinion 63 to release the carriage. The retarder may be dispensed with and the carriage may be released for tabulating pur poses in any other manner which may be preferred.

From one aspect of my invention the tabulating mechanism thus far described constitutes what is commonly termed a denomi- 1 national or decimal tabulator and is capable of doing ordinary denominational tabulating work. After one or more column stops 43 have been properly located in the rack 42 any one of the tabulating keys 53 may be pressed to move its associate lever 45 into the path of the column stops and to release the carriage. hen released the carriage will move leftward under the pull of its main spring and will continue to more until the first column stop comes in contact with the actuated or projected denon'iinationzd stop 47. Then the operative key is released. all the parts will return to normal position and the carriage by the cooperation of the tabulating stops will thus be located with reference to the printing point in accordance with the t-abulating key 53 which has been selected and operated, this location being in the first column and at a predetermined denominational position therein.

It will be understood that the tabulating mechanism as thus far described will operate always to bring one of the stops 4? into cooperation with the first column stop that has to pass the set of denominational stops and that each column as determined by the location of the column stops 43 before be ginning work will be brought to printing position in regular sequence. To pass columns in which it is not desired to make entries it is necessary with the mechanism as thus far described to operate one of the tabulator keys 53 as many times as there are columns to be passed, thus effecting a corresponding arrest of the carriage at each of these intervening columns. In order to do away with the loss of time thus occasioned, a column selecting mechanism is provided. The column selecting mechanism in the present case comprises key-controlled devices which are preferably associated with the tabulating mechanism above described so as to enable the keys 53 to be at will operated to release the carriage and arrest itat the beginning of predetermined columnar positions, intervening columns being skipped or passed. Said devices are in part supported on an angular bracket or flanged plate 69 which is suitably secured to the under side of the rear portion of the top plate 2 and extends downward therefrom. Said devices comprise a stop member or slidable plate 70 which is formed with a longitudinal slot 71 through which pass shouldered screws 72, said screws as shown in Fig. 10 screwing into the bracket 69 and providing bearings on which the plate 70 may slide longitudinally back and forth. Normally the lefthand end (viewed from the rear) of the slot 71 is maintained in contact with the left-hand screw 72 by a coiled spring 7 3, one end of which is secured to the plate and the other end to a pin 74 depending from the top plate 2. The under side of the plate 70 is provided with a series of saw teeth 75 which are a letter space distance apart and as viewed from the rear the left-hand end of the plate 70 is reduced in width and bent rearward at right angles to provide a lip or stop 76.

With the parts in normal position as shown in Fig. 3 the contact face of the stop 76 is in the plane of the outer face ot the adjacent lever 45 j ust under the top plate. It will be understood from Fig. 2, which shows a side view of the parts in normal position, that the levers are not normally in the path of the stop 76; but the keys may be depressed to bring the levers 45 in the path of the stop. livotally supported on the screws 72 are

parallel arms

77 and 78, said arms being arranged between the rear face of the plate 71 and the head of the screws 72 as will be understood from Fig. 10. The arms extend upward through an 0 ening or slot 2 in the top plate. Pivota ly supported at 79 at the upper ends of the

arms

77 and 78 is a stop member 80 which is channeled or U-shaped to embrace the supporting arms. The inner end of the stop member 80 is provided with an upturned lu or finger 81 which serves as a column se ecting stop cooperating directly with the column stops 43 as presently to be explained. Ordinarily, however, the stop member is depressed as shown in Fig. 4 so that the column selecting stop 81 lies below the planes of the column stops proper 43 and cannot be engaged by them. The means for depressing and raising the stop member 80 and stop 81 will be explained later on.

Integral with the arm 78 and below the pivot screw 72, is an arm 82, the

arms

78 and 82 constituting a lever which is slightly angular. Pivoted at 83 to the lower end of the

lever

78, 82 is an arm or pawl carrier 84 provided with a pawl tooth 85 which is adapted to cooperate with the teeth 75 on the slide 70. The pawl tooth 85 is constantly urged upward to engage with the teeth 75 by a coiled spring 86 secured at one end to a pin 87 on the pawl arm 84 and at the other end to a pin 88 projecting rearward from the bracket 69 through the slot 71. A detent pawl 89 is pivoted at 90 to the bracket 69 and is maintained in engagement with the teeth 75 by a leaf spring 91. The stop member 80 is adapted to be raised into operative position from normal position by means which comprise a roller 92, said roller being pivoted at 93 to the upper end of an arm 94 which in turn is pivoted at 95 to a plate-like lifter 96, said lifter being provided with vertical parallel slots 97 through which pivot screws 98 pass into the bracket 69, said screws cooperating with said slots to guide the lifter upward and downward on the supporting bracket when actuated. The roller 92 co-acts with the outer or, as viewed from the rear, right-hand face of the

lever

78, 82 and is constantly maintained in engagement with said lever by a coiled spring 99 which is secured to pins 100 and. 101 projecting rearward respectively from the arm 94 and the lifter 96. The lifter is provided with an extension 96 which, as viewed from the rear, extends leftward in front of and across the path. of the levers 45 and is provided with a rearwardly extending shelf or lip 96' which is adapted to co-act with said levers 45 to limit their movements. Said levers 45 are, however, provided with cut-outs or slots 102 which when the stop lip 96 is positioned as in Figs. 2 and 8, will embrace the stop lip when actuated and permita full and complete movement of the levers 45. The slide 96 is provided with a downwardly extending screw socket 103 which receives the threaded upper end of an arm 104, said arm extending downward and being pivotally connected at 105 with the rear arm of a lever 106 which lever is fulcrumed on the rod. 48. The lever 106 is arranged at the left-hand side of the set of levers 45 and between said levers and the arm 67 (Fig. 5). At the opposite side of the set of levers 45 is an arm 107, saidarm being pivoted on the rod 48 and extending horizontally forward therefrom. Pivotally connected with the forward ends of the levers 106 and arm 107 are upwardly extending arms or stems 108 which are guided through openings in the guide plate 52 and are connected at their tops by a bar or key 109 which is arranged at the rear of the row of keys 53 and extends longitudinally thereof, so that while holding the bar 108 in operated position, the operator may actuate with the same hand or finger any one of the keys 53. Normally the bar 109 is maintained on a level with the row of keys 53 by a coiled spring 110, one end of which is secured to the arm 107 and the opposite end to the guide plate 52 (Fig. 2). Said spring also serves to normally maintain the lifter 96 in its lower or inoperative position as illustrated in Figs. 2 and 4.

The lifter 96 is provided with a T-shaped extension comprising an upwardly extending arm or stem 111 which is also off-set rearward from the body of the lifter to clear other parts of the mechanism. At its top the stem is provided with oppositely off-set fingers 112 and 113, the finger 112 cooperating with the pin 87 to control the pawl arm 84 as presently to be described; while the finger 113 is adapted to cooperate with a pin 114 extending rearward from the detent pawl 89 to control said detent paw'l. Integral with the bracket 69 and underlying the slidable plate 70 is a lug 115 formed with two stop faces 116 and 117, the stop face 117 being horizontal and the stop face 116 being inclined leftward from the vertical as viewed from the rear.

Suppose that with the carriage at the beginning of the line of writing and with the parts in normal position, that is, with the lifter 00 lowered as in Fig. 4, it be desired to skip or pass several columns and to write in, say, the third column from the left-hand margin. It is to be noted that at this time with the slide 00 down as in Fig. 4, the finger v113 will be in engagement with the pin 114 so that the detent pawl 80 will be inoperative on the teeth 75 while the pawl tooth 85 will be maintained by the stop face 117 in inoperative position. Furthermore the arm 94 will be drawn over by the spring 90 and the roller 92 will be pressed against the lever arm 82 so as to maintain the stop 81 down in inoperative position. The spring 86 assists somewhat to perform the last named function. As a preliminary to skipping or passing columns the operator first presses the bar or key 10$) in order to bring the column selecting mechanism into operation. The depression of the bar 109 operates to swing upward the rear arm of the lever 106 and raise the arm 104, said arm in turn raising the lifter 96 which slides upward over the bracket 9 from the Fig. 1 to Fig. 3 position, being arrested in the latter position by the engagement of the lower ends of the slots )7 with the stems of the screws 98. During the upward movement of the. lifter the finger 113 will release the pin 11:4. and the spring 01 will force the detent pawl 80 into engagement with the teeth 75. At the same time the roller 92 will slide upward over the edge or face of the

lever

78, 82 and after it passes the fulcrum of said lever and engages with the upper arm 78 will swing said arm leftward as viewed from the rear. This movement of the arm 78 will cause a corresponding movement of the arm 77 and will lift the stop member 80 and stop 81 into operative position as shown in Fig. 3. During this movement of the arms and the stop member the lower lever arm 82 will swing rightward and will withdraw the pawl tooth 85 from the stop face 117. As soon as the pawl tooth disen ages from the stop face the spring 86 will 5 aw said pawl tooth upward into engagement with the rack teeth 75. Furthermore, the upward movement of the lifter elevates the extension 96 carrying the stop lip 96 upward so that said stop lip is raised out of the path of the notches 102 in the upright arms of the levers 45 and so that when actuated said notches cannot engage with the stop lip 96. Maintaining the bar 109 in depressed position the operator next depresses the third key 53 from the lefthand end of the row since it is desired to skip the preceding columns and write in the third column. The depression of the key 53 operates to swing the associate lever 15 on its fulcrum, lifting the upright arm of said. lever upward and forward until the front edge of said lever above the slot or notch 102 contacts with the stop or lip 96". As shown in Fig. 9 this movement advances the lever arm into the path of the stop lip 76 but does not permit the stop 17 to rise into the path of the column stops. Concurrently with the advance of the actuated lever 45 to the Fig. 9 position the carriage will be released as has been heretofore described and will be drawn leftward by the main spring, bringing the first column stop 43 into engagement with the column selecting stop 81. After such engagement and during the further advance of the carriage, the first column stop will operate on the column selecting stop 81 and will swing the stop member 80 rightward as viewed from the rear, causing a corresponding leftward movement of the pawl member 84:, this movement of the pawl member continuing until its end contacts with the stop face 116 which serves to limit the movement and jam the pawl tooth 85 into the rack 7 5.

The parts are so proportioned that when the arrest of the pawl arm takes place the stop member will have been swung sufficiently far to the right and downward to lower the stop 81 out of the path of the first column stop and permit said column stop to slide over the top of said stop 81 and continue its advance. During the leftward movement of the pawl arm 84 the pawl tooth 85, being in engagement with the first of the rack teeth 75 as shown in Fig. 3, will advance the slide plate one step leftward, overcoming the sprin 73. After the first column stop has released the stop 81 the stop member 80 will be restored to the Fig. 3 position by the spring-pressed roller 92, causing a retraction of the pawl arm 84, the pawl 85 slipping back over the contiguous rack tooth and engaging with the second tooth space from the left. The retraction of the slide plate 70 will, however, be prevented from the detent pawl 89, said pawl serving to retain said slide plate in its advanced position one step leftward from normal position. The continued movement of the carriage will bring the second column stop 43 into engagement with the column selecting stop 81 and will cause the steps as above outlined to be repeated so as to advance the slide plate70 an additional space or ste thus bringing the sto lip 7 6 on said sli e plate into contact wit the vertical arm of the projected lever 45 which lies in its path. Fig. 6 shows the parts in the last described relationship just prior to the release of the stop 81 by the second column stop. When said second column stop releases the stop 81 said stop 81 and connected parts will be restored to the position shown in Fig. 7, the pawl tooth 84 being retracted to engage with the third space between the rack teeth 75, counting from the left and as viewed from the rear. The last step of the advance movement of the carriage brings the third column stop into engagement with the column selecting stop 81 as shown in Fig. 7 and causes the arrest of the carriage because the column selecting stop is prevented from yielding to the third column stop by reason of the engagement of the stop face 76 with the projected lever 45. This will be understood from a consideration of Fig. 7 from which it will be noted that the slide plate 7 O on which the stop plate 76 is rigid is held from advance; that consequently the rack teeth cannot move; that by reason of the engagement of the pawl tooth S5 with said rack teeth the pawl arm is held from movement leftward; and that said pawl arm maintains the

lever

78, 82 from movement, said lever, of course, holding motionless the stop member 80 and stop 81.

When the carriage is arrested the key 53 and bar 109 may be released. The release of the key 53 permits the restoration of the parts controlled thereby including the lever 45 and the carria e releasing devices to normal position as s own in Fig. 2; while the release of the bar 109 permits the retraction of the lifter 96 to the Fig. 4 position. During the retraction or downward movement of the lifter the finger 113 will operate on the in 114 to swin the detent pawl 89 out of t e rack 75 and the finger 112 will engage the pin 87 and swin the pawl arm 84: down out of the rack 75, bringing the pawl tooth below the stop face 117 so that when the roller 92 begins to act below the fulcrum of the

lever

78, 82 the pawl arm 84 will be moved leftward and the pawl 85 will be brought under the stop face 117. As soon as the pawls 89 and 85 disengage from the rack teeth 75 the slide plate 70 will be retracted to the normal position shown in Fig. 4 by the spring 73.

It will be noted that the operation above outlined causes the carriage to be released and to be advanced and arrested at the beginning of the third column, the first and second columns preceding being skipped or passed. If, now, it be desired to write at a particular denominational position in the third column, the operator has only to actuate the desired key 53 to cause the carriage to be released and arrested in the corres onding denominational position in said third column. In other words, my present invention enables intervening columns to be skipped at pleasure and the carriage to be released and subsequently arrested at the beginnin of any desired columnar position, the num er of columns skipped being only limited by the number of the keys 53. The

column selecting mechanism is brought into operation by the depression of the bar 10!) and while holding said bar depressed any of the keys 53 may be operated to select corresponding columns. After this arrest of the carriage at such selected column the release of the bar 109 again permits the keys 53 to be operated for denominational purposes. The next succeeding column stop will cooperate with the levers 45 to determine denominational positions in the selected column.

It is my observation that in most cases of tabulating work involving a large number of columns, such work, for example, as train sheets or the like, it is desired to begin writing the data in most of the columns at the beginning of such columns and it is only in comparatively few of the columns that it is desired to select a particular dBl'lOll'lll'lELtlOlltll position. The present form of my invention is particularly adapted to this class of work in which from time to time it is necessary to skip one or more columns and begin writing at the initial position in a subsequentcolumn. In such case all that it is necessary to do with my invention in use is to count from the column in use to the column in which it is desired to write next and then after actuating the bar 109 to operate the corresponding key 53. It will be understood that in each instance in order to determine the proper key 53 to operate, it is necessary to count the number of columns from the one in use to the desired column and not the number from the beginning or left-hand side of the sheet.

It is to be noted that by my present invention I combine a plurality of column stops and a single cooperating stop, the stops when cooperating yielding one to the other, with means for preventing such yielding when said single stop cooperates with a predetermined stop of said plurality of stops; that the yieldin in the present instance takes place on t e part of the single cooperating stop which is adapted to be moved by one or more of the column stops out of their own paths during the run of the carriage, each of such movements of the single stop which may be termed the column selecting stop, operating to step a slidable stop member toward its point of final arrest so that eventually when the selected column stop comes along, the single stop will not yield but will operate to prevent further movement of the carriage; that I provide a stop combined with a plurality of stops cooperative therewith for denominational purposes, said plurality of stops being cooperative with still another stop for column se lect-ing purposes; and that said plurality of stops, which in the present case are on key controlled levers, cooperate at one time. directly with the column stops for denominational purposes and at other times with interposable stop devices in order to select particular columns in which to arrestthe carriage, any intervening columns being skipped or passed.

Where in the sub-joined claims a single stop or a single cooperating stop or the like is referred to, it is to be understood that the term means a stop having a single stopping or arresting face in contradistinction from a stop member which, although it may be a single piece, is provided with a plurality of stop faces'whieh are operative at different times.

Various changes may be made without departing from the spirit and scope of my invention.
