1 at their rear. The carriage is constantly urged leftward by a spring drum or motor (not'-shown),-to which it is connected by a of escapement devices which operate throng connecting mechanismjicomprising I a feed vrack lion the carriageandfwhich con-' stantly me sheswith a, v feed pinion 15 mount ed on a horizontal shaft 16 .su 'portedlon the bed plate. The feedpinion is ooselymount- ,ed on said shaftbut is normally connected to turn, therewith in printing direction throughdevices connectingsaidpinion with t a toothed escapement wheel 17 fixed to said shaft 16. Said devices comprise a spring pressed pawl-18 pivotedto the escapeme'nt. wheel and which normally engages with the teeth ofithe feed inion 15. ;Theescapement wheel is normal y ogged or' prevented from turnin by devices comprising a dog ,19 whereby t e carriage is held. frommoving from right to left under theimpulse of; its

the control ofthe iescap'ement mechanismiby i p a ve to Separate the awl-1 from the feed pinion l5, said devices comprising; a sleeve 20 slidahly mountedon the e scapement wheel shaftiand providedwith flanges 2 1 spaced apart near its rearv and -tion forward on the sto operate with a pin 23 fixed to the pawl 18 and projecting rearward therefrom through a slot in the escapement wheel. Said sleeve 20 is controlled from the novel tabulating mechanism by devices presently to be described.

In order to make the tabulator mechanism as compact and unobtrusive as. possible, we preferably mount the column stops inside the machine, as it may be termed in contrast with the usual mounting outside of the machine. To this end a pair of angular brackets 24 are arranged one near each end of the carriage, beneath the rear bar 6-8 (Figs. 1 and 5). The brackets are formed with holes 25 which receive headed screws 26 whereby they aresecured to the carriage and depend from its rear. At their lower ends the'brackets are, erforated to receive the reduced rounded aring portions 27 of a toothed stop bar 28, the ends of the reduced portions being threaded to accom-' 'modate nuts. 29. It will be observed that the stop bar is covered by thecarriage and is slightly above the lower carriage bearing. The stop bar is formed at its upper and lower faces with kerfs or cuts 30 providing teeth at, letter space intervals, which teeth receive between them a set of column stops 31. These column stops are of ordinary-construction being U-shaped so asto fit over the'stop bar between the teeth at the top and bottom thereof and being provided with rearwardly projecting stop faces 31. Pivotally secured at 32 to the side of each stop bar is a yoke-like spring member 33 terminating in end stops 34 and 35 (Figs.

1, 5, 7 and 8). When in inoperative poslbar each stop 31 is held by the co-operation of the stop end 35 with the lower corner of the stop bar 28 in the position shown in Fig. 8,-this osi'tion corresponding with that of most of t e stops in Fig. 5 and also-with that of the stop nearest the observer in Fig. 1. Thus maintained'the stops arein inoperative position or unset as it is sometimes termed. To set these stops or position them for co-op eration with the key actuated decimal stops they are selectively slid rearward in a manner hereinafter described. During this slidmg movement the spring or retaining member 33 swivels or turns slightly on its pivot 32, enabling the-stop end 35 to clear the lower corner of the stop bar and permit rearward sliding movement of the stop 31 on said-bar until arrested by co-operation of the stop end 34 with the top front corn'er of the stop'bar as shown in Fig. 7 In other words, the stops 31 are'projectible or slidable rearward 'on their support to operative position and are also retractable or slidable forward on their support to inoperative or unset position. The ,stop settlng and retracting means comprise key the machine.

which are associated with the key operated decimal stops.

The decimal or denominational stop devices are mounted on a tabulator frame which in turn is .detachably mounted on Said tabulator frame comprises a casting 36 having a hooded top portion 37 and depending side arms 38 which.

curve outward at their lower ends and are connected by an angular cross bar 39 (Fi s. 1, 2 and 3), Detachably secured to t e front upper portion of the "hood 37 by screws 40 is a comb plate 41 provided at its top with arib or projection '42, the front of said comb plate being provided with upper and lower combs 43 and 44 for 'guidin the decimal stops The lower ortion o the comb plate is undercut or 0 -set rearward from the upper portion. The frame comprising the casting 36 and the comb platel41 supports a set of decimal stop levers as well as certain of the stop setting and un-setting devices, all these parts being attachable and detachable with the frame. When in place on the machine, the frame 36, 41 rests on the top-of the frame bar 2, the ledge 2 at the top of said bar 2 providing a convenient seat for the horizontal portion of the cross bar 39 of the frame. The bed plate or trough 12 is cut out to accommodate the hooded upperportion 37 of the'detachable frame, the cut-outof said bed plate indicated at 45 being at the right-hand side of the escapement shaft 16.. The upper edge of the cut-out 45 is formed with a square-cut groove or depression to receive the rib 42 at the top of the detachable frame 36, 41. After said rib has been fitted in its groove, thus securingthe upper end of the frame, the lower end portion or cross bar 39 receives headed'screws 47 which are threaded into the ledge 2,'thus rigidly securing the detachable tabulator framev in place; The decimal stop levers 48, of which there are ten in the present instance, are vertically arranged within the frame or casting 36, their upper end portions curving forward within the hood and terminating in forwardly extending heads or stop portions proper 49 which areadapted to slide through the combs 43 and 44 .and are guided therepivot-a1 support the stop levers'spread orfan laterally outward and their lower portions are received in slots or guide openings indicated at 52 formed in a guide plate or comb 53 that is horizontally disposed and extends forward beneath the cross bar 39, the plate 53 terminating at its rear in an upstanding portion 54 which is secured as by rivets 55 to the rear face of the vertically disposed portion of the cross bar 39. Above the cross bar each lever 48 is provided with a rearwardly projecting lug 56 over which fits the forward end of a coiled restoring spring 57, the rear end of said spring being housed in a hole 58formed in the vertical part of the cross bar 39, the rear end of the spring abutting against the part 54 which covers the hole at the back. he springs 57 tend to swing the lower arms of the stop levers 48 forward and the upper arms backward, maintaining the stop blades or heads 49 in retracted or inoperative positions within the hood 37 ,r the rear edges of the stop levers normally resting against astop bar 59 secured within the hood. The lower-ends of the stop levers 48 are curved rearward and slightly forward, terminating in rounded noses'60.

(lo-operative with the noses 60 area set of key operated'slide rods 61, one'foreach stop lever 48, the slide rods being arranged within the base in parallelism and extending fore-and-aft of the machine, being supported at both rear and front by detachable supporting members. terminates at its rear end in'a hook-like portion' comprising a flattened vertically disposed upright portion 62 and a forwardly extending horizontal guide portion 63. The

hook-like portions of the slide rods are supported and guided by a U-shaped guide bar 64 terminating in' cars 65 which receive screws 66 that are threaded into bosses 2 on the cross plate 2. The upper and'lower edges of the cross portion'of theguide bar 64 are formedwith slots or depressions indicated respectively by the numerals 67, 68, the lower slots 68 receiving and guiding the rear portions of the slide rods proper 61.

while the upper slots 67 support and guide the forwardly extending portions 63 of the slide rods and prevent the rods from turning on their axes. Each upright flattened portion is opposite the associate nose 60 against which it is ada "ted to act when-the rod 61 is slid rearwar .to actuate the associate lever 48. The front ends of the slide rods 61 are sup orted and guided by a sheet metal guide p ate or frame 69 "which in cross section is of an inverted U-shape (Figs. 1 and 6). The guide frame 69 is secured by screws 70 to thefront of the frame memher 3 of the machine, the screws being accessible through"holes' 71, formed in the front portion or plate of the guide frame. The end portions of the front plate or flange 69 are cut away so as .to expose theend portions of the rear plate or "flange 69", these end portions providing tabs 72. The upper Each slide rod" 61 cross portion ofthe frame 69 is inclined forward and downward and has secured to it by screws 73 a slottedindex plate 74 under which may be arranged asuitable number strip containing indicia which are exposed through the slot in the plate 74. The-forward ends of the slide rods 61 project forward beneath the bottom edge of the frame plate 3 and receive finger pieces 7 5. 7 These nger pieces are cylindrical in shape and may be made of fiber, some suitablecomposition, or other desired material. The rear faces of the finger pieces 75 have metal disks 76 pressed or otherwise secured in them, said disks having tapped holes which co-operate with the threaded forward ends of the slide rods 61 to d'etachably-secure the finger pieces or keys 7 5 to said slide rods. The front flange or plate of the frame 69 is formed with holes indicated .at 75 of a suitable size to permit of the passage therethrough of'the keys'75', the rear end portions of saidkeys normally resting on the bottoms of said holes which serve as guides for the keys as they slide through during operations of the tabulating mechanism. When one of the keys 75 is pushed in, its slide rod 61wil1 be'moved or slid longitudinally rearward, causing the'flat portion 62 to'press againstithe'nose 60 of the associate stop lever 48 and swing said lever on its pivot 50-, projecting its upper or stop end 49 forward into the path of those of the column stops 31 which have been set or projected rearward on their su porting bar 28.. The actuation of one of t e dec'imal stop levers 48 by its key 75 is effective automatically to re ease the carriage from the controlof its escapement devices, the releasing means comprisin' ,as shown in Figs. 1 to 4, a universal bar 7 arranged horizontally behind the levers 48 somewhatbelow their pivotal axis. Said universal-bar is provided with up-turned ears 78 which receive'sc'rews 79 that fasten the universal bar to the lower ends of arms80 comprised" in a supporting frame which further includes a cross bar 81 connecting the arms 80, said arms bein angularly bent from the cross bar whic extends across the set of levers 48 at' their front. The up'per'ends of the arms 80 receive pivot screws 82 which are threaded into the sides of'the arms 38 and provide a pivotal support for the frame 80, 81 and the universal'bar member 77, '78 carried thereby. The lower ends of the arms 80 are squared off and rest in contact with the upper face of the universal bar 77 so that the latter is held in rigid relationship with its supporting frame- The left-hand arm 80 has an upward extension 83 which is curved or bentleftward and terminates in a horizontally disposed-finger or engaging portion 84 which fits between the flanges 21 of the sleeve 20. When one of the stop levers 48 is actuated by its key 7 5 the lower arm of said stop lever swinging rearward about its pivot will contact with the front edge of the universal bar 77 swinging the latter rearward on its pivots 82 and causing the finger 84 pressing against the forward flange 21, to slide the sleeve 20 forward so that the beveled flange 22 acting against the pin 23, will lift the pawl 18 from the pinion 15, thereby releasing the carriage. It will be observed from Fig. 1 that the universal bar 77 lies normally some distance behind the rear edges of the levers 48 so that the universal bar will not be actuated until the latter part of the stroke of said levers, giving time for the associate stop 49 to be positioned before the carriage is released. hen the tabulator key is released, permitting the actuated parts to be restored to normal position, the tabulator universal bar 77 and connected parts will likewise be restored to normal position through the operation of a.

coiled restoring spring 85, the rear end of which is seated in a depression 86 in the back wall .of the hood 37, the front end of said spring fitting over a lug or projection 87 on the universal bar.

The stop setting devices whereby the column stops 31 may be projected or slid rearward on their supporting bar 28 into operative or set positions are shown in Figs. 1, 2, 3, 6, 7 and 8 and comprise a crank arm 88 terminating at its free end in a rounded nose which lies just forward of the lower branches of the column stops 31. Said crank arm is provided with a hub 89 which fits over and is secured to the left-hand end portion of a horizontal rock shaft 90, having a stationary bearing 91 projecting upward from the horizontal portion of the bed plate 12. Fixed to the right-hand end portion of the rock shaft 90 outside its bearing is a downwardly projecting arm 92 having a curved or cam face93 which is adapted to be acted against by the forwardly projecting nose 94 of a stop setting lever 95. Said lever is of the general shape of the set of levers 48 and is arranged at the right of said set and inside the right-hand casting arm 38 to which the lever 95 is pivoted at 95*. The lower arm of said lever 95 is guided in a slot of the plate 53 and terminates in a nose 96 which is adapted to be acted on by the flat vertical portion 97 of a slide rod 98 which. also has an upper guiding portion 98*, said slide rod 98 corresponding in construction with the slide rods 61 and being disposed, at the right of said set of slide rods, the slide rod 98 being guided in the right-hand pair of guide slots 67 and 68. Thefront end portion of the slide rod 98 passes through a guide opening in the right-hand tab 72, being guided and supported thereby. Fixed to the front end portion of the slide rod 98 is a stop set key or button 99. When the stop set key 99 is pressed in, its slide rod 98 willbe slid rearward, actuating the stop setting lever 95 and causing the noselike upper end portion 94 of said lever, acting against the cam edge 93, to rock the shaft 90 and swing the crank arm 88 rearward, causing said crank arm to press rearward against the lower branch of that particular column stop 31 which may lie opposite to said crank arm at the time, and sliding said stop rearward, or setting it as has been described. It will be apparent that it is only necessary to move the carriage endwise to position to bring the desired column stops in line with the stop setting arm 88 and then to operate the stop setting key 99, in order to set the desired column stops in position for use. In Fig. 5 severalcolumn stops are shown as set or projected in position for co-operation with the set of decimal stops, heads or blades 49 when these are projected or swung forward into position as indicated by the dotted lines at one of the decimal stops 49. It should here be noted that since the set of decimal stop levers 48 is off-set to the right of'the middle of the machine to clear the escapement devices, it is necessary correspondingly to elf-set the set of column stops, this being done of course by adjusting the position of the column stop bar 28 in correspondence with the off-setting ofthe frame 36 of the decimal stops. The universal bar 77 is cut away at its right-hand end at 77 behind the lever 95 so that the stop setting mechanism will not actuate the carriage releasing mechanism; and there is a similar cut-out 7 7 a at the left-hand end of the universal bar.

The stop retracting, or unsetting de vices as they are sometimes called, comprise a cam arm or wiper 100 horizontally disposed and pivoted at its "right-hand end, which is bent laterally rearward, on a pivot pin 101 mounted on a lug 102 on the righthand face of the hood- 37 and projecting downward from said lug. The arm 100 extends leftward across the front of the lower part of the comb plate 41 and under the overhanging portion thereof. Said comb plate is provided near its left-hand free end portion with a double cam face 103 which is in line with the stop portions 31 of the column stops. At itsleft-hand end the arm 100 is provided with a rearward extension or finger 104, best shown in Fig. 9, which serves as a guide and support for the wiper member 100104 in cooperation with a guide, slot 105 out in the left-hand endof the comb 41 and a. second guide slot 106 formed or cut in a thickened portion of the hood 37 at its left-hand side (Fig. 9). When the cam or wiper 100 is swung horizontally back and forth it is preventedfrom saggin "or getting out of position by the guide n'ger104 co-operat-fl ing with itsguide' slots. Said cam member is actuated by a lever 107 arranged at the left of the setof] levers 48'. and generally conforming in shape to said levers, being guided by" the left-hand one of the slots 52, but having a separate pivot 108 supportedby the left-hand arm 38. The upper portion orhead of'the lever 107' difi'e'rs, however, fromthe heads 49' of'the levers'48, said lever 107 having awider head or end portion 109 which ts .in a special "wide slot 44 in the comb plate 41. Below the head 109 the lever 107 is provided "with a forwardly extending hook 110 whoseiupturned end lies under the" cam portion 103 of the arm 100, said cam portion being undercut to provide a shoulder 111, with which the hook 110 may co-operate. It will be seen, more especially from Fig. 8, that the upturned end of the hook 110 lies'just in front of the shoulder 11 1 while the lower end of the head 109 liesjust behind the arm 100, there being an open space Y 112 between the head or blade and the hook.

The construction is such that "the arm 100 'isthus loosely connected with the lever 107 bywhich it is positively actuated in both directions,,said arm being adapted tobe swung'forward by the lower end of the head 109 and being adapted to be-swung backward by the action of the hook 110 on the shoulder 111. The means for'zop era'ting the lever107 for this purposecomprises a slide'rod 113 which is similar in construction to the slide rod 61 and is, ar

rangedat the left-hand end otthe setof;

slide rods. The slide rod 113 is provided with an upright actuating portionllopposite the lower end of-the lever 107 and lso with a guide portion 115, the rear end hand lower an upper slots 68 and 67 inthe bar 64. The slide rod113 extends forin-the leftforward of or unsetl'key 116 is pushed; in, it will slide the rod '113 rearward,.causing it toactuate the lever 107 which will be swung-omits lease of the carriage.

of the'lever'107 swings forward from the pivot 108. Said lever107. being opposite the left-ha'nd cut-out 77 in the universal bar 77 will not actuate said universal bar and consequently will not efi'ect, there: As the upper arm position shown in Figs. 1 and 7 to the position shown in Fig. 8,the blade .109 acting against the arm 100 will'swingthe latter on its pivot 101 and carry the-double cam or wiper 103 into posiltion for co-opeim' co 'umn stops'31 e-' tion with the projects portion of said" rod and its guide. ortion; 115' co-operatin respectively with t e left low their stop portions 31. Consequently if the operator maintain the unset key 116. pressed in, andat the same time release the carriageby hand and move it back and .forth or; fromone sideto the other, the

double cam or wiper 103 will act on the projected or set column stops 31 to slide them back'on their stop bar or towards the front ofthe machine to unset orinoperative position, thus clearing the tabulating mechanism so that a new setting of the c0 1 liability o actuating the wrong keys by mistake is reduced.

. will be seen that by our present invention. .there is provided an unusually compact, and simple decimal tabulating mechanismwhich includesdevices for setting the column stops and also retracting or unset- .ting them; that'said tabulating mechanism is readily attachable to thet pewriting ma chine and detachable there rom; and that it. doesnot greatly add apparently tothe size-of the machine since t e column sto devices instead of bein outside as is usua in this-case are arrange within the machine, so to-speak, being disposed underthe car riageand between it and its bed plate or trough.v v. i
