JOI-IN WALDHEIM, 0E NEWARK,.NEW JERSEY, ASSIGNOR, BY MESNE ASSIGNMENTS,

TO UNION TYPEWRITER COMPANY, OE JERSEY CITY, NEW JERSEY, A CORPORA- TION 0E NEW JERSEY.

To all fr0/wm tm/ay concern Be it known that I, JOI-IN W'ALDHEIM. citizen of the United States. and resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Type-Vrit-ing Machines, of which the following is a specication.

My invention relates to typewriting machines and more particularly to tabulating mechanism.

The main objects of my invention, generally stated, are to provide comparatively simple and eflicient tabulating mechanism by which any desired columnar position may be selected at will, and by which any desired denominationalc position in a column may be 4selected, so that the carriage may, after a single run, be arrested at any desired columnar field or at any desired denominational posit-ion within any selected columnar field.

A further Aobject of my invention, genen' ally stated, is to provide comparatively simple and efficient means whereby certain parts of the tabulating mechanism may be.

locked in the position to which the said part'or parts may be set or moved under key control, and to automatically release the locking means during a subsequent operation of the tabulating mechanism.

A still further object of my invention is to provide tabulating mechanism for arresting the carriage at variable posit-ions in 4the travel thereof, the variable position of arrest of the carriage depending on a variable movement of a fulcrumed member, and a variation of the fulcrum of said member bringing about a variation in the movement which may be given to said member.

Patented Mar. 26, 191.2. Serial N o. 663,984.V

'w-w of Fig. V3 and looking in the direction of the arrows at said line. Fig. 2 is a detail perspective view of a group of two of the key actuated levers, together with certain of the associated parts for actuating the denominational stops. Fig'. v3 is a. fragmentary horizontal sectional view of the machine, the section being taken on the line wof Fig. l and looking in the direction of the arrows at said line. Fig. 4 is a fragmentary detail sectional view of the denominational stop levers and certain of the associated parts, the section being taken on the line g/-y of Fig. l and looking in the direction of the arrow at said line. Fig. 5 is a diagrammatic side elevation, partly in section, of the tabulating mechanism, the view illustrating the parts in theV shown only so much of a typewriting mac chine as may be necessary to arrive at an understanding of my invention.

I have shown my invention embodied in the present instance in a No. l5 Yost machine, except in so far as the tabulating mechanism of that machine may be modified ror replaced by features of the present invention and except in so far as that machine may be modified to eect an embodiment of my present invention therein. Moreover, some of the parts of the typewriting machine are conventionally repre sented in order to simplify the showing. It should'beV understood, however, that the invention may be embodied in various styles of typewriting machines and that various changes may be made in the construction toV facilitate such embodiment.

The present case is one of three companion applications filed by me of even date herewith, the other applications bearing Serial Nos. 663,982 and 663,983 respectively. Considered from certain broader aspects there are features in common in all three cases. The broader claims to features common to all three applications are included in case Serial No. 663,982, whereas any feature common alone to caseSerial No. 663,983 and the present application are broadly claimed in case Serial No. (363,983, theclaims herein beingrestricted to features not disclosed in either ot' the other companion applications.

The frame of the machine comprises side plates l united by a rear cross plate 2 and top plates 3 and 4t. A carriage 5 is mounted to travel from side to side of the machine on anti-friction balls or rollers 6; a cylindrical platen 7 being carried by the carriage. The carriage is moved in the letter feed direction under the power applied thereto by the usual spring drum 8. The usual or any suitable cscapement mechanism is employed to control the carriage in its step-by-step letter feed movement, only so much of the escapement mechanism being shown as may be of value in the consideration of the present invention. Thus a horizontally disposed feed rack 9 is provided with upwardly extending arms 10 pivoted at 11 to depending lugsv 12 on the bottom of the carriage. A spring 13 tends to force the feed rack forwardly into engagement with a feed pinion 14. which isoperatively connected to the usual escapement devices. A cross bar 15 is fixedly connected to the frame of the machine, and constitutes a support for a bracket 16, iixcd to the cross bar by screws 17. A releasing device or lever 1S is pivoted on a shouldered pivot screw 19, carried by the bracket 16. An engaging face or shoe 2O is provided on the release lever for contact with the feed rack 9, to effect a rearward movement thereof against the pressure of the spring 13 to disengage the feed rack from the pinion and thus free the carriage from control of the escapement mechanism. The carriage release device 1S is actuated in a manner which will hereinafter appear.

A column stop bar 21 extends substantially throughout the length of the carriage and is supported thereby on arms 22 which project from the carriage. The column stop bar is provided with teeth 23 on opposite sides thereof-for the reception of bifurcated sheet metal column stops 2e in the interdental spaces between the teeth on the bar. It will be understood that adjacent interdental spaces are situated a letter space distance apart and that the column stops may therefore be adjusted to different letter space positions along the column stop bar throughout the length thereof. From an inspection of Fig. 1 it will be understood that the column stops 2-1 have contact portions which extend rearwardly from the column stop bar at varying distances, so as to provide a series of graduated column stops, each having a contact portion in a path of travel different from the others. The longest column stop 24 is situated at the right and the shortest at the left of the series on the column stop bar. In the present instance four column stops are shown.

A series of denominational stops 25 is arranged for movement fore and aft of the machine in openings in a guide plate 26 fixed to the top plate 4 of the machine. This guide plate is provided with slots or openings 27, as shown in Fig. 11, to support the denominational stops against lateral movement and to guide said stops in theirmovements fore and' aft of the machine. In the present instance each denominational stop' constitutes a part of a variably movable actuating lever or fulcrumed member 28, the levers extending upwardly in the rearpart of the machine and being connected to key controlled actuating devices in a manner which will hereinafter appear. Each of the fulcrumed members or levers 28 has a segmental slot 29 which extends longitudinally thereof intermediate the ends of the lever. lVhen the members 28 are in the normal position all of the segmental slots 29 are in register and a single fulcrum or pivot rod 30 extends through the slots 29. From an examination of Fig. 4t it will be observed that spacing sleeves 31 surround the fulcrum rod 30 and are arranged intermediate the levers 28 in order to maintain them properly spaced apart on their pivot rod.

f The ends of the fulcrum rod 30 are secured by screws 82 to supporting arms 33, arranged outside of the series ot' levers ,2S and extending fore and aft of the machine. These supporting arms 88 are pivotally supported at their forward ends on a shaft 34k, which latter is fixed by screws 35 in bearings in upwardly extending bracket arms 86. The arms 36 are, or may be, formed as a part of a cross bar 37 fixed to the frame of the machine. From an inspection of Figs. 1 and 3 it will be observed that a universal bar 38 has its bent ends riveted at 39 to the side supporting arms 3?) which support the fulcrum rod 30. The universal bar 38, side arms 33 and the fulcrum rod 30 thus constitute a frame adapted to swing around the shaft 34 as a center. This frame is connected to one end of a contractile spring 33a, the other end of said spring being connected to one of the bracket Aarms 36 so as to exert a pull on the frame to return it to the normal position, shown in Fig. 1. The u'nder side of the universal bar 38 is provided with a example, at a, ZJ, c and CZ in Fig. 1, without l disturbing the levers 28 from their normal positions. Obviously, however', each ofthe .levers 28 -is adapted to receive a variable movement, depending von the position of the fulcrum rod 30 in the slots 29.

r[he key actuated means by which a vari'- able position of the fulcrum rod 80 is attained, in the present `instance, comprises a series of four so-called. column selecting keys 4l, arranged in `rear of and above the denominat-ional keys 42, and in the rear of the ordinary printing keys in the keyboard of the machine.. Each column selecting key is provided with a stem 43 slotted to receive the forward end of a key actuated lever 44, pivoted on a pivot rod 45,-fixed to the frame of the machine. From an inspection of Fig. 8 it will be observed that collars 46 are secured by screws 47 to the pivot rod 45 outside o-f the right-hand and left-hand key levers 44. `Intermediate spacing sleeves 48 are mounted on the pivot rod 45 between the levers 44 to maintain them properly spaced and to prevent t-he movement of the levers along the'pivot rod 45. Each of the levers 44 is, as will be seen, pivoted intermediate of its endso as to constitute a lever of the' first order, the rear end of each of the first three of said levers, counting from right to left` having an interiorly threaded bearing port-ion 49 forthe reception of a screw 50. Each screw constitutes an adjustable contact device for coperation with one. of the c0nv tact faces 40 on the universal bar 38. The

equal extent of key depression which is lim` ited by a contact face 51 on each lever engaging the shaft 34, as shown in Fig. 6, thereby arresting the fulcrum carrying fra-me and fulcrum rod 30 in their movements to the shifted positions. The stepped faces 40 on the universal bar 38, however, afford varying extents of movement by different column selecting keys 4l, through a differential or variable movement of the frame and the fulcrum rod 30 which is carried.v thereby, as has been hereinbefore explained. Each key stem 43 of the column selecting keys, is guided in openings in guide plates 52 and A coiled expansion spring 54 surrounds each ke v stem, and bears at its lowerend against the guide plate and at its upper end against the associated lever 44 to elevate the key and return the parts connected therewith to norl'nal position. Each key stem is limited in its upward movement by an enlargement 43a at the lower end thereof engaging the guide plate 53.

Referring now to the mechanism by which the denominational stops are actuated, itV

openingsin the guide Vplates and 5?. Each key stem 55`is slotted to receive the forwardly projecting` arm ot' an angular lever, indicated as a whnle by the reference numeral 56. From an inspection of Fig. 2 it will be seen that earl-.i ot'V these levers comprises a forwardly extending arm 57, carried by a yoke-like membe1 nhich extends transversely of the machine and has rearwardly extending varms 59 which are pivoted on a pivot rod 60, said rod being secured at its ends to the frame of the machine. These yoke-like members 58 are nested as shown, andare maintained. spaced of the'series of denominational keys whichr are connected to the yoke-like portions of the key levers. From an inspection of Figs. l and 2 it will be seen that adjacent to each of the inner arms 59 of the denominational key levers there is arranged an actuating lever or member64, provided with an offset laterally extendingprojecticn or lug which extends beneath the inner arm 59 of the adjacent denominational key lever.

These Ylevers 64 are pivotedon the pivot rod 60 and each has a depending arm which is connected at 66 to a rearwardly extending push link 67. Each link, at its rear end, extends through al guide opening ina guide plate 68, fixed to the frame of the machine. The yrea-r end of each link 67 is pivoted at 69 to the lower end of an associated denominational stop lever 28 and by which the lever is supported andV actuated. A contractile spring 7 0 is connected at one end to the depending` arm of a lever 64 and at its forward end to a plate 71 secured to theframe of the machine. Each lever 64`has an upwardly extending arm 72 for purposes which will hereinafter appear. It will be understood that the returning spring for each lever 64 is effective to return the associated key actuated denominational lever 56 and its denominational key 42 to normal position. The pull exerted by the spring is likewise effective to move the link 67 forwardly and return the associated denominational stop lever 28 to its normal position around the fulcrum rod 30. The forward movement of the lower end of each stop lever 28 is limited by contact with the guide plate 68, whereas a rearward movement of the lower end of each stop lever is -limited by a set screw 73, received in a tapped opening in the frame of the machine.

llSO

At the depression of a denominational key, movement is transmitted through the associated denominational lever 56. The movement of the latter around the pivot 60 is effective to move the associate lever 64 against the pull of the spring 70, and to actuate the corresponding denominational stop lever 28. A turning movement of the latter around its pivot 30 is effective to move the corresponding denominational stop into the path of one or another of the column stops, depending on the extent of movement of the lever 2S, and its extent of movement is dependent. as hereinbefore explained, upon the position of the pivot rod or fulcrum 30 for the levers 2S. The four positions of the pivot rod 30 to vary the extent of pivotal movement of each of the levers 528 are shown at a, Z2, c and d in Fig. l. It will be understood therefore that an actuation of a column selecting key 4l is first effected, in order to determine the position of the fulcrum rod 30, and to determine with which of the column stops t-he denominational stops are to coperate; in short, to select the column or columnar field where the carriage is to be arrested by the cooperation of the different denominational stops therewith. Thus, should the operator desire to arrest the carriage in the second columnar field, it is merely necessary to depress the second column selecting key from the left, bearing the index numeral 2. The eect of the depression of this key is to bring the contact device 50 carried thereby into engagement with the corresponding contact face or step 40 on the differential universal bar 38 and to swing the frame, of which the said bar is a part, around the shaft 34 as a center. The depression of this column selecting key is effective to move the frame when the pivot rod 30 will be positioned, as indicated at Z) in Fig. l. If, therefore, any denominational key be depressed while the fulcrum rod 30 is in this position. then the corresponding denominational stop will be projected into the path of the second of the column stops Q4, counting from left to right, to arrest the carriage within the second columnar field and'at a denominational position within said field corresponding to the particular denominational key depressed. It will be understood that each denominational stop will at this time be moved a uniform distance and will be brought into the path of this same second column stop, as hereinbefore indicated.

I have found it desirable to provide locking means for locking the fulcrum rod 30 in any one of the three positions indicated at 5, c and (Z in Fig. 1 to which the fulcrum rod may be shifted, in order that the operator after depressing a column selecting key may release it and be free to actuate the denominational stop at will and without the necessity of maintaining pressure on the column selecting key until after the denominational key is actuated. To this end I have provided each key lever 44 with an upwardly extending engaging member 74 having inclined edges Or cams 7 5 and 76 on the front and rear sides thereof, respectively. The lower edge of each inclined edge terminates at a locking notch or slot 77. A universal locking device or bar 7 8 is carried by arms 79 arranged on opposite sides -of the series of levers 44. These arms are pivoted on the pivot rod 60 and are held against movement longitudinally thereof by collars 79a. The locking bar is therefore adapted to swing around said pivot rod 60 as a center fore and aft of the machine. This locking bar is adapted to coperate with the inclined edges 7 5 and the forward locking notches 77 of the engaging devices. A second locking bar 80 is connected in a like manner to arms 81 which are pivoted on the pivotrod or shaft 60. This locking bar 80 is adapted to cooperate with the inclined edges 76 and the rear set of locking notches 77. A contractile spring 82 is connected at one end to a pin 83 which extends upwardly from the locking bar 7 S, whereas the opposite end of y said spring is connected to a pin 84 which extends upwardly from the locking bar 80. The spring therefore exerts a pull to cause the locking bar 78 to be held against the inclined faces 75 on the members 74. It also tends to cause the two bars 7 S and S0 to be drawn toward each other, but the bars under certain conditions which will hereinafter appear are limited in their movements toward each other by a projecting arm 85 which extends forwardly from one of the arms S1 for engagement with an arm 79 of the forward locking bar, as shown in Fig. l. The relative movement of the bars 7 8 and SO toward each other is thus limited. A contractile spring 86 is connected at one end to the pin 84 and at its opposite end to the shaft 34. The pull of this spring is greater than the pull of the spring 82, and vthe spring S6 tends to normally maintain the parts in the position shown in Fig. l. If at this time a column selecting key be depressed, as indicated in Fig. 6, the rear end of the corresponding key lever will be elevated. The inclined edge or cam 75 will effect a forward movement of the locking bar 78 to move it against the pull of its spring 82 until the forward locking notch 77 has been brought into register with the forward locking bar. The spring 82 is then effective to move the locking bar 78 into the notch, to lock the rear end of the actuated lever 44 in its elevated position, thereby locking the associated contact device 50 in its shifted position and maintaining the fulcrum 30 up in the position to which it has been shifted on the depression of the column selecting key. The parts will remain in this position until a denominational key is depressed to effect a forward movement of the denominational stop. Vhen this is done the movement of the lever 56 is effective to produce a. movement of the corresponding lever G4, thereby moving the upper arm 72 of this last mentioned lever forwardly to effect a forward movement of the locking bar 80 into the rear locking notch 77, as represented in Fig. 5. As the locking bar 8O moves foru'iardly the contact arm 85 is effective to force the locking bar 78 to the releasing position as shown in Fig. 5, thereby disengaging it from the locking projection 74. There is a slight drop between each engaging device 74 and the locking bar 80 to assure proper engagement between these parts when a disengagement is effected between a locking device and the locking bar 78. It will be seen that while the locking bar 78 vis disengaged from the key actuated lever 44 it, nevertheless, is at this time maintained locked against return movement by the locking bar 80. Vhen, however, the carriage has completed its travel and been arrested by a coperation of the previously selected column stop with the denominational stop controlled by the particular key depressed by the operator, then the denominational key may be released and as it returns to normal position the associated shown in Fig. l, where it is again inposiarm 72 will move rearwardly. This movement of the arm 72 releases the locking bar `8O, and the returning spring 86 moves the said locking bar out of the rear notch 77 and out of engagement with the locking projection 74 on the previously depressed column selecting key 44. This key lever 44 may therefore return to normal position as tion to be actuated by the depression of the -appropriate column selecting key and to be automatically locked in its actuated position. During the return of the locking bar 78 to normal position it is prevented from rengaging in the forward notch 77 of the actuated lever 44 by reason of the drop which has been effected-between the engaging member 74 on the actuated lever and the locking bar 80, as previously described. From the foregoing it will be seen that at `the depression of a'column selecting lief. t0 move the fulcrum tothe appropriate position determined by the particularcolumn selecting key actuated, the parts will be automatically locked in the actuated position. That is to say, the column selecting key will be locked in the depressed position, the contact device will be locked in its actuated position up against the universal bar 38, and the frame carrying the fulcrum rod 3() will be locked against return movement under the pull of the spring 33a and in the positionto which it has been moved by the depression .of the column selecting key. It will also be understood that upon the first depression of a denominational key the locking mechanism will be automatically released to afford a return movement of the parts to normal position.l

I have provided means whereby the release of the carriage to effect a tabulating operation or movement does not take place until the column selecting key has been depressed and locked in its operative position, and until a denominational key has been depressed. Vln order to provide against the release of the carriage until after a column selecting keyV has been depressechl have provided means whereby the carriage release mechanism is normally inoperative and cannot be released unless a column selecting key has been actuated prior to the actuation of a column selecting key. Thus each of the levers 64 is provided with a rearwar lyeXtending engaging Aprojection 87, which, in

the normal position of the parts shown mounted to swing fore and aft of the machine. Tlie rock shaft carries a rearwardly extending crank arm 91 provided at its rear end with a stop 92 which engages a cross bar 93 of a frame 94. The rear end yof the crank arm 91- has pivoted thereto at 95 an upwardly` extending link 96 which in turn is pivoted at 97 to the inner ends of two toggle links 98. The rear end of the rear toggle link is pivoted at 99 to a bracket 100, secured to the cross bar 15, whereas thel forward end of the forwardv toggle link is pivoted at 101. to the carriage releasing device 18.

It will be understood thereforethat a rearward movement of the universal releasing bar 88 is effective to turn the crank arm 91 upwardly, thereby transmitting movement through the links96 and 98 to the carriage releasing device 18, which movement isy effective to shift the feed rack 9 rearwardlyI out of engagement withv the coperative feed pinion 14. As hereiiibefore stated, thev normal position ofthe parts is such, however, that the actuating projections 87 will not engage the releasing bar 88, .so that a depression of a denominational key, when the parts are in thev positions represented in Fig. l, would be ineffective to prod-nce a tabulating movement of -the carriage, inasmuch .as the carriager release mechanism could not be actuated. I have provided means, however, controlled by a depression of a column selecting key for elevating the universal bar 88 into the path of the enhereinbefore referred to, comprises parallel side arms which are pivoted at 102 to rearwardly extending arms 103 on the bracket 3G. The frame therefore is mounted to turn on the pivots 102 as a center, in order that the forward end of the frame may be elevated from the position shown in Fig. 1 to that indicated in Fig. 5, where the releasing bar is held in coperative relation with the engaging projections 87, on the levers 64. The means for swinging the frame in the manner specified consists, in the present instance, of hook-like extensions 104 on the key levers 44. One of these depending hooklike engaging projections is provided on each lever 44, and they normally extend beneath the pivot rod 90. An upward move` ment of the rear end of any of the levers 44 is effective to bring about an engagement between the engaging hook 104 on the lever and the pivot rod 90 to swing the frame 94 around its pivots 102, from the position shown in Fig. 1 to that indicated in Fig. 5. At this time, therefore, the releasing bar and the carriage release mechanism controlled thereby are adapted to be actuated, to release the carriage from the control of the escapement mechanism to afford a free travel of the carriage until it is arrested by the cooperation of a column stop with the projected denominational stop. A contractile spring 105 is connected at one end to a pin 10G projecting from the crank arm 91. The opposite end of this spring is connected to a pin 107 which extends from the fixed cross bar 87. The power of this spring is exerted to pull the arm 91 down, thereby moving the releasing bar 88 forwardly to normal position. rlhis also effects a down pull on the link 96 to tend to maintain the releasing device 18 in the position shown in Fig. 1. The sto-p 92 engages the cross bar 93, thus limiting the downward movement of the rear end of the crank arm 91 and the parts controlled thereby. The power of the spring 105, connected in the manner described, is likewise effective to move the frame 94 downwardly at its forward end and maintain the universal bar out of cooperative relation with the projections 87. rlhe spring 105 therefore acts for a two-fold purpose. Stops 108 are carried by the side arms of the frame 94 and contact with the cross bar 37 to limit the downward swinging movement of the frame 94 under the pull of its returning spring 105.

From the foregoing description it will be understood that in order to eect a tabulating movement of the carriage it is necessary to first actuate an auxiliary or column selecting key in order to render the key controlled carriage releasing mechanism operative; that such depression of a column se-'A lecting key is effective to determine the position of the fulcrum 30 for the denominational stop levers 28 that when the fulcrum is shifted it is automatically locked in its shifted position by the engagement of the locking bar 78 with a projection 74 on the actuated column selecting lever 44; that a denominational key may now be depressed and its depression is effective to give the requisite amount of throw of the corresponding denominational stop lever, to bring the corresponding denominational stop into the path of the particular column stop which has been selected, as determined by the operation of the particular column selecting key actuated; that at or about the time the denominational stop has been given the requisite amount of movement to interposition it in the path of the proper column stop, a release of the carriage will be effected to afford a movement of the carriage until such time as the projected denominational stop and the selected column stop are brought into cooperation to arrest the carriage; that when pressure is released on the denominational key, the locking mechanism will be automatically released to afford a return movement to normal position of the column selecting key and the parts controlled thereby. It will also be understood that the variation in the position of the fulcrum rod 80 brings about and determines the variation in the extent of movement that may be transmitted to each of the denominational stops; that the means by which the fulcrum rod 30 is shifted relatively to the denominational levers 28 constitutes leverage changing means by which the extent of movement of each denominational stop is controlled and the columnar position of arrest of the carriage is determined, and that the variable movements of the denominational stops are toward and away from the column stops or in the direction in which the denominational stops move to bring them into cooperative relation with 1 the column stops.

It should be understood that when the part-s are in the normal position the fulcrum rod 30 is maintained in the lowermost position, as indicated in full lines in Fig. 1, and that this position is one of the four which determines the extent of movement to be transmitted to the denominational stop levers. In other words, when the fulcrum 30 is in the position indicated at a in Fig. 1, the denominational stop levers will receive their greatest extent of throw in order to enable the denominational stops to be interposed in the path of the shortest column stops, or the first of the column stops, counting from left to right, and it is unnecessary to shift the fulcrum from this position. The left-hand column selecting lever bearing the index numeral 1 therefore terminates before it reaches the universal bar 38, and has no contact device 50 like the other three column selecting key levers. It 'follows Athat when; this first column selecting key lever is depressed, no movement- Will be transmitted to the fulcrum carrying frame, and the fulcrum will' remain in the position in'- dicated at a ine Fig. l. Inasmuch, hovvever, as the carriage release mechanism cannot be actuated until after the depression of a-column selecting key I have provided a column select-ing key bearing the index numeral l in order that this key may be actuated to carry the releasing bar 8S up into position Where it may be actuated by the engaging projections 87. In other words, While it i's unnecessary to actuate the first of the column selecting keys in order to determine the position of the fulcrum 30, it is necessary to actuate said key in order to render the denominational stop lmechanism operative to release the carriage.

From a considerationv of the foregoing description it will be seen that if the operator desires to use the construction asa mere column selecting mechanism, it is only necessary to depress the column selecting key and then depress theE denominational key bearing the index mark 'indicating the decimal point. The carriage will: be released on the depression ofthis last mentioned key and Will be arrested after a single travel at the desired columnar field. If, however', it is desired to select a given denominational position, say, at ten thousands position Within, say, the second columnar field, `the column selecting key bearing the index numeral 2 is first depressed and the ten thousands denominational key is then depressed, and the carriage Will after a single run be arrested in the ten thousands position in thel second columnar eld.

I believe that I am the first to devise the combination of cooperative tabulator stops and leverage changing means operable at Will to cause a variation in the extent of movement of certain of said stops relatively to others to vary the point of arrest of the carriage, and Wish to be understood as claiming such subject-matter broadly.

Various changes may be made Without de'- parting from the spirit and scope of my invention.

What I claim as new and desire to secure by Letters Patent, is

1. In a typeivritingmachine, the combination of awcarriage; and tabulator mechanism for arresting the carriage at variable positions in the travel thereof, said mechanism .including afulcrumed member movable varying extents and by the variation in extent of movement of whichV a variation in position of arrest ofL the carriage is determined, and means for varying the position of the fulcrum of said member and thereby cause a variation in thev extent of movement Which may be given said' member.
