WALTER J'. BARRON, OF NEW`YORK, N.Y.J, ASSIGNOR, BY MESNE ASSIGNMENTS, TO UNION TYPEWRITER COMPANY, OF ILION, -NEW YORK, A. CORPORATION 0F NEW YORK.

Be it known that I, WALTER J. BARRON, citizen of the United States, and resident of the borough of Brooklyn, cit of New York, in the county of Kings andy State of New York, have invented certain new and useful Improvements in Type-Triting Machines, of which the following is a-specification.

This invention'frelatesto tabulating mechanisms of writing machines, and more particularly to that class of tabulators in which,

at the operation of a denomination key, a stop corresponding thereto is projected, and the paper carriage is also automatically released and permitted to run down under the tension of the usual carriage spring,` until arrested by said projected stop .at a point where the writing of a number having the denomination of the operated key may be begun.

In using machines of this class, operators sometimes fail to hold the denominationkey in workin@ posit-ion until the completion of the run of the carriage, Aparticularly when there is a long jump or gap between columns, and in consequence the carriage is prematurely rengaged toits letter-feeding devices and arrested thereby, so that the succeeding number is written out of column.

One object of the present invention is to produce a machine in which a single'stroke of the selected-key insures that the carriage shallrun to the next column and be arrested the denomination denoted by said key, Without any attention 011 the part of the operator beyond merely pushing the key to the working position, so that while the carriage is runnmg he is at liberty to move his hands into position to begin promptly the writing of the number, whereby he is relieved of care and liability to mistakes, and is also enabled to execute the work more expedi- ,tious1y.

Another object of the invention is to cause both the type-operating keys and the spacing -key to be locked during 4the jump of the carriage, so as to prevent accidental operation of thecarriage feeding dogs by any of said.

keyswhich would have the effect of causing thlcarriage to b stopped in an erroneous osition; and also so' as to prevent printing uring said jump movement of the carriage.

Other objects will appear hereinafter. My invention consists 1n certain features of construction, combinations of devices and the carriage when tabulating. Fig. 3 is a perspective view of the column stop shown at Fig. 2. i Fig. 4 is a. fragmentary view ofanother means for preventing rebound of the carriage. Fig. 5 is a rear view and Fig. 6 a plan of the machine shown at Fig. 1. Fig.7 is a skeleton view similar to Fig. 1, but showing a denomination-stop locked in working position,A the carriage locked thereby1 against rebound, and the type-keys Fig. 8 is an enlarged view of the Lipper portion of a de. nomination-stop lever. Fig. 9 is a front elevation of a guide comb for the denomination stops, two of the latter being shown in cross-section. Fig. 10 is a sectional plan showing a portion of the denomination stops, whereof one is shown projected and caught by an adjacent tooth of the giide comb, which latter is drawn in horizontalI section. Fig. 11 is a plan showing a column stop. a fragment of its supporting rack, and a denomination stop engaged by the column stop and released thereby from its detaining comb tooth and also showing the denomination stop as caught by a column stop hook, whereby reboun of the carriage is prevented. Fig. 12 isa View similar to Fig. 10, but showing only a single denomination stop and its associated detent and comb tooth. Fig. 13 is an enlarged perspective fragmentary view of the devices illustrated at Fig. 11, the column-stop rack being omitted. Fig. 14 is an enlarged front edge view of the upper portion of a denomination-stop lever.

In the severalviews portions are omitted or broken .away to disclose the invention more clearly, and similar parts are designated by similar numerals of'reference.

The writing machine comprises a'rectan gular base l, corner posts-2 erected thereon,

a top plate 3 surmounting the posts, key, levers 4 fulcrumed in the base, links 5 con# necting said' key levers to type bars 6, a

being secured in opposite standards 17 pro.

vided upon the top-plate. Upon the'ca'r. riage 1s hinged at 18 a `frame which carries a rack 19, meshing with an underlying pinion 20, the latter being connected to'an es.

capement wheel 21, which is controlled by a feeding dog 22 and a detent dog23, both carried upon the upper end of a dog rocker l24 pivoted at 25 in a bracket 26 depending from the top plate, and having forwardly extending arms 27, -which support, by means .of hooks 28, a universal 'bar 29 that extends across the machine beneath the key levers.l The advance movements of the carriage are effected by a pro elling sprin vcarriedin a barrel 30, which isconnected y a strap `31 toa hook 32 depending-from the carriage.

Column stops 33 of the usual general construction are disposed along a rack 34, which extends inthe direction ofthe run of the paper carriage,and is secured to a frame 35 mounted'thereon. j

\ Denomination stops 36, arranged at letter space intervals, are formed upon the upper ends of vertical levers 3.7101: the first order, which are fulcrumed upon a transverserod 38 and se arated by' plates 39, and'at. their lower en s are provided with horizontal push rods 40, bearing keys' 41 and havin returning springs 42. The said fulcrum ro 38 .is supported in a frame 43,*which is clamped upon the base by cleats or flanges 44 and 45, and 'is at its upper end supported by a yoke 46, which engages the carriage rail'16. The levers 37 fan out at their lower ends, and thekey rods 40 diverge forwardly.

A. carriage.- releasing bar 47, arranged transverselyin front of the upper portions Ioff-.thezs'top levers 37, is carried by a pair ofvertical rocker arms .48, which are prv otedVV at their vlower ends on shouldered s- 49. Upon the left-hand rocker ,arm 481s formed a forwardlyprojecting arm 50 carrying an adjustable screw'51 adapted to depress the rear end of a forwardly extending release lever 52, which is pivoted between its ends at 53 upon a bracket' 54, `and is provided at its forward end with a head 55 adapted to lift the carriage-feedY rack 19 out Aof mesh with its pinion 20. v

The denomination stopsy 36y projectforwardly from the levers,.and work in: a ver- -i'scut or stamped ar rearwar A,tical guide comb'56', which preferably is formed 'by `a pair ofslotted plates placed edge to edge arid fastened upon the frame j In each stop directed locking tooth 59, which projects to the right, and 4normally stands vjust behind thecomb 5 6. Before assemblage, the upper portion of each of the stop levers 37 is bowed 43by screws 5'."\(see Fig. 1y

slightly towardv thelright, as illustrated at Fig. 9,so`that it is-necessary to sprin them slightly toward the left when intro ucing the stops between the comb teeth, rsaid teeth being` in register with the spacing plates 39 at the lever hubs. By yth-is meansthe levers are given a lnatural or inherent spring tension toward the i right, whereby, upon theirfor- Ward movement, the vpi jecting teeth 59 thereon are forced beyond the comb teeth 58 and then caused to snap or latch "over 'the front faces thereof,'as shown at Fig. 10,

thus locking thev stopsv against return 'movefuient-- In `op'eration, after settin the column stops'at the desired 2 ointsa on'g the rack 34, a key41 of these ected denomination is pushed rearwardlygand bymeans of rod 40 1t swings its Vlever 37 uponthe axis'38, thus moving the'stop 36 carried-at the upper end *of said'lever-forwardly into the path of the ,column stop 33. The stroke of the lever and -key is limited by a shoulder which is formed upon the 't/nppftlieflever and contacts with thel rear face -ofthe comb, while at the same time, "owing to the lateral tension of the upper-arm of the `lever'37, the'tooth 59 thereon is caused to'snapV into engagement with its associated datent or comb tooth, 58, as illustt'rated -at`Fig. 10, thus locking the denomination stop in working position. The release ,bar47 ,is also borne forwardly bysaid projected stop lever 37, and by means of the arm 50 and the screw51 depresses the rear l end of 'lever '52, the' forward end of which lifts the carriage feed rack 19 clear of 'the '.p'inion-20,'whereby thee carriage is freed V--from theeontrol of its escapement devices, land is rapidly Aadvanced by Athe driving spring inthe--barrel 30 and Ya strap 31,

whereupon' the succeeding column. s top .33 labuts against the projected "denomination stop'36, thus arresting the carriage in position to begin thel writingofa numberof the selected denomination. Y By the impact of the column stop, the denomination stop is moved from the figure 10 to the figure 11 position, the force of the carriage-propelling springbemg suicient to overcome theinherent spring tension of the lever 37, so that thedenomination stop, be'- ing 'thus disengaged from its detent, is free to move backward under the tension of the,

returning' Vspring 42.

The pull of. said fspringis sufficient to overcome the friction between the columnstop and the denomination stop, as Well as that `between the denomination stop and the combtooth, and

to draw the denomination stop back out ofv y be liable, if permitted to become rengaged to its escapementdevices during such re bound, to settle at an erroneous position. To avoid this I provide means for preventing such rebound; said means consisting preferably of an angular latch pivoted upon each cohunn stop and consisting of a hooked portion 60 which extends parallel with the run of the carriage, and a base portion 61 -which is parallel with the column stop and is pivoted at 62 to the upper portionof the latter a spring 63 being mserted inthe arm G1 and curving over the corner of the column stop and bearing against the front vertical face thereof. lVhen, during the run of the carriage, the beveled edge 64 of the latch strikes the projected denomination stop, it is cammed up over said stop, and under the tension of the spring 63` snaps down over the same, as illustrated in Fig. 13, thus eiectuallypreventing rebound of the carriage. This locking of the carriage does not, however affect the above `narrated releasing action of the column stop upon the denomination stop, and hence the latter returns immediately to normal position under the tension of the spring 42. Upon such return, the latch GO of. course no longer acts to prevent reverse movement of the carriage,

Asothat the latter may then be moved freely in either direction if desired. It will be perceived that the denomination stop and the latch coperate only momentarily, but

this is sufficient to check the rebound of the carriage or at least limit such rebound to a distance less than a letter space which practically is the same thing as preventing absolute rebound of the carriage.

In the form shown at Figs. 2 and 3, the angular latch arm G0a is formed integral with a portionof the column stop, instead of being pivoted thereon, and its tooth projects upwardly; 'While upon the top of each denomination-,stop` lever is pivoted at 69 a forwardly evtendingpawl 70, which. is

adapted to be cammed upwardly by the beveled face 64a on the column stop latch,

and then to snap down into locking position, under the forceof a compression spring 71, which .is insertedbetween the top of the stop leverand a 72 formed upon the pawl in rear of its pivot 69. Thus said pawl 7D momentarily .prevents lrebound ofthe of this pawl normally stands just above a,

series of teeth 78 formed along the upper edge of the carriage rack bar 19a-the direction of said teeth being such that they may coiiperate With said pawl to prevent back- -vward movement of the carriage;l while permitting advance movement thereof. When the carriage-release lever 52 is operated, as

above described, and the rack 19 is thereby lifted to the dotted line position at Fig. 4, the said teeth 78 are caused to mesh with the pawl 75, so that during the jump of the carriage said pa wl rides freely over the teeth; but when the carriage is arrested by the engagement of its stops the pawl and rack coperate to prevent rebound of the carriage. Upon the return of the projected denomination stop to normal position, together with the carriage-releasing devices, the rack 19 dropsagain and frees the teeth 7 8 from the'control of the pawl 75, so that the carriage may be moved freely to the right when desired.

The construction shown in Fig. 4 has been.

made the subject-matter of'a divisional application filed by me Nov. 14th,. 1907, Serial No. 402,141, the construction shown in Fig. 4 being specifically claimed in said divisional application; mechanism being broadly claimed herein.

Upon the under side of the said carriagerelease lever 52 at its rear end is formed a tumbler or lug 79, which is adapted on the down movement of the lever to drop in from',

of a stop lng 80 projecting upwardly from the rigid carriagedetent` dog 23, so that when a denomination key 41 is operated, not only is its connected stop set and locked in working position, together wifi the carriage-releasing 'devices but also by the engagement of said tumbler with said, lug the operation-of the dog-rocker 24 is prevented., so that should the operator either accidentally or prematurely strike either a type key or the spacing key, it would fail to operate, since the dog rocker is thereby prevented from -moving during the transit of the carriage or as long as the denomination stop re mams locked in working position. y B this means I insure that the carriage sh l be stopped at the exact position determi ed at the operation of the-denomination h/ey, .sov

that liability of mistakes is avoidedf/ It will be seen that the denomination stops considered as a set have an ixnovable ,or

the antirebound .fixed position relatively to the longitudinal movements of the carriage; that is to say the said set is arranged constantly in a similar position, thus enabling narrow columns to 'be Written in order upon the page, if desired; that a spring latch moves with each denomination stop; that means engage with said latch for holding the stop in its projected position; that a carriage release device is also detained automatically in Working position by the denomination stop latches; that with a series of latches is combined means engaging withveach latch for detaining the carriage releasing devioe'in operative position, said latches each having a part that is movable into .the path of a part upon the carriage so as to' enable the latter to bear directly upon said latches and move them Nclear of said detaining means, each latch being directly releasable by the contact of the carriage therewith; and that the carriage releasing devices are operable by all of said latches. It will also be seen thatveach denomination stop is provided with a tooth which projects laterally therefrom; that each of said stops when projected is moved laterally a distance less than a letter space in projected position;

l that the means for locking said stops in their projected position are released by the carriage at the moment of the impact of the projected stop by a column stop; that is`to say, that the Contact of the column stop with the denomination stop and the release of the carriage occur practically at the same instant and without the necessity of making a prolonged additional movement of the carriage after the. contact of its stop with the projected denomination stop, the stop releasing movement of .the carriage being considerably less than a letter space and being so'small as to be negligible, and there being.

a simultaneous lateral movement of both the column and the projected denomination stop for this slight distance; and that the latches comprising the spring levers 37 and the teeth 59 thereon all control the carriage releasing mechanism so as to holdv it in Working posi- 'device (36 or 60a) and vthat upon the return of the denomination stop to the normal position the latch becomesdisconnected from the detaining device; that a column stop and a' denomination stop thus coperate to pref the rebound of the carriage; thatvthe devent rebound of the carriage as` well as to coperating'stops and adapted to engage the Aother of said stops; that a set of column stops-upon `the carriage coperates with a set of denomination `stops upon the machine frame; that a set of devices is carried by one of said sets'of stops and 'adapted to coperate with they other set of stops for checking nomination stops. are movable in the path of the column stops and the latches carried upon the latter; and that each of said latches engages a part which is automatically moved out of engagement therewith upon the return of the carriage releasing-device to normal position. It will also be observed that the carriage feeding devices are controlled by a series of type-operating keys, and that the movement of the latter is revented after Vthe carriage is released and efore it is arrested by the contact of the stops 33 and 36, or while the carriage release device is locked in Workin the key loc ing device, the carriage' releasing device and the denomination stopjtare'si'multaneously lmoved to working position and.' severally held there by the tooth 59; that said key locking device is setby the carriage releasing bar 47 arranged in the path of the denomination stop levers 37 "and that said releasing bar operates the releasin lever 52 which carries the tumbler 79 which intercepts the movement of the dog rocker. It will likewise be seen that the meansl for preventing a` letter space rebound of theearriage are actuated by the impact of the carriage; that they a're rendered e'eetive by the travel of the carriage and that a spring pressed catch which prevents the rebound of the carriage is actuated or is moved against its springtension by the impact o the carriage.
