depression of t-he keys. A plurality ot `rows of keys are provided as many rows as th number of numerical orders in which it is desired to operato, each row comprising ynine keys numbered 'trom one to nine. (ine key in each row may be depressed tor each operatioi'n and when that key is depressed, it is locked in its depressed position and the other keys in the row are locked against dcpression. When a key in a row is. depressed, 1t permits a slide-bar corresponding 'to that row to move in the direction of its length a dist-ance corresponding to the value of the key depressed, ano as this slide-bar moves thus, it carries a pawl around upon a gear Wheel With which that pawl coacts, the

movement of the pawl thuslbeinp; commensurate with the movement et the slide-bar. Upon actuation of the operatingv device, all the pawls which have been moved thus are turned. to their initial positions, moving their gear wheels `with them7 andthe `fear wheels v cause corresponding rotation ot the number Wheels, which either indicate the result of the operation or are positioned for printing theoresult upon a suitable paper strip. ln Combination with these parts a carrying; mechanism is employed whereby any one oi" the mechanisms can cause the mechanism ot the next.- hilejher order to advance one unit as will be well understood.

In accordance with the present invention,v

wheel actuated on the return ot that slidebar to its initial position and the cari-ving mechanism corresponding` to that ninnber wheel are all mounted upon a single support so that all of these parts tor one nu- .,Inerical order niay be assembled upon that L)support and thereafter a suitable number of these units may be placed together in a machine. The preferred 'forni ot support is a strip oi-lsjheet-meta'i ot' suitable centig-- uration and this support may have one or more integral 'port-ions lthereof bent at an angie to the body portion ot the support and of the requisite length to serve as spacers for separating the several supports jthe required distance. Fig: l shows a machine made up of eight such units`r this machinebeing adapted for operation in dollars` and cents upto. one million dollars. The. lconstruction ot' each ot the units employed inthe machine `is best illustrated in Figs. 4 to 7'. Referring to theseI tjg'ures, it will he bseen that the supportingw'member for the unit consists of a piece of sheet-metal l, 'having itsifforward end Q turned at. a right angle to the body-portion of the strip to v.form aspacer, as will be hereinafter de-y scribed. A roW of nine keys 3 is mounted 'j'lpon thef'support l, these keys being numtiered from one to nine beginning at the j trout oi the machine. `Each ot these keys il is mounted upon a stein l and is adapted to slide vertically upon the support l; for this purpose each keystem 1l is 'provided with two slots through which extend the shanks ot studs entering' openings .in the support l, llach key is normally held in a 4raised position by means of a spring G one end et ivhich is secured to an eye 7 formed upon the key-stein Lland the other end ot which is secured to one ot' the studs 5. At its lower end each key is provided with a downwartflly eritendiiur projection 8 and in rear ot this a 'laterally extending projection t). lsoeach key is provided with a laterally extendingy pin or stud l0. The lower ends oi all of the keys in the row are adapted to eoact with a pivoted sliding-bar ll of angular cross-section- This bar is j'iivotallyv erally extending; end 2 ot' the support i and the other in a similar lateral projection lintegral with support i. in the body-portion oi.r the bar il are a phirality oi" spaced openings or slots ot progressively increasing length, as shown in Fie. 7, through which the projections 8 on the key-stems are adapted to project when thc'keys are depressed.

The bar il as above stated is ot angrtllar cross-section, it being' bent lengthwise to 'form a side-wall i3 and at the top thereof a flange 14 directed toward the key-stems. in the bottom wall of the bar ll is an opening and the upwardly turned end ot a link l5 enters loosely into this opening'. .il spring;` it is connected at one end to the link i5 and at the other end to the lateral extension 2 of the support l so that this spring' tends to draw the link l5 and the slide-intr 'il forwardly. A spring` 17 is connected at one end to the link l5 and at the other to an ej l tormed upon the slide-bar il so that this spring tends to turn the slide-bar l1. on .its pivots 'tar enough to carry the end of the wall. 'i3 ot the slide-bar opposite the end oit a stud 1 8 mounted upon the extension 2 et the support l.y llilhen the bar 1l is in this position7 shown in Fig. G, it is held against movement actuated by sprinlgl 1G. When any key 3 is depressed the extension S thereoin is projected through its corre spending opening- 1.9 in the slide-har ll and thereafter the lateral projection 5) on the key-stem enger1 the slide-bar 1l and rocks` that bar on its vpivots sutiicient to carry the end of the side-wall 13 free of the studlS; when this occurs the spring 16 draws the link l5 and slide-har l1 *forwardly until further movement of the slide-bar is arrested by the projection. 8 on the'stem of the key which has been depressed engaging the rear Wall of the slot 19 inA bar ll through which it has been projected. When the slide-har il is rocked. on its pivots in the i'nounted in oi'ieuing's termed one in the latv machine lirmly between tlicln. One of these tie-bars may he so positioned that it will serve as a support 'for the several links 15 to prevent the. latter from moving` vertically downward.

The mechanism for o'ierating the number Wheels .vill now be described. As above stated each unit is provided with :i gear- Wheel 26 operated by :i pawl mounted on ay pand-carrying erin 4l pivotally mounted on stud 25 and having the link 'l5 pivotally connected thereto. The paxvl Z7 is not pivotally mounted directly upon the arin 4l but instead is pivotally mounted upon a. lever 42 which is pivotally mounted upon the puWl-carrying arm Lll. The pivn otal connection between paivl 27 and the lever 42 passes through a. slot 44e provided in the arm 4d. Pivotally mounted upon the paul-carrying' arm is a trigger #lo havinga lateral projection 4G which is adapted to engage a shoulder formed on the lever l2 so as to hold the lever and the paivl 27 carried thereby against movement about the pivot 43 of the lever except when it necessary to carryover. A spring` 4&7 is connected at one end to the trigger t5 and at the other end to the pivotal connection be tween the paivl 2T and lever 4Q.. This spring' serves two purposes, it tends to hold the trigger down upon the end oi lover 4L and in eoaction with 'the shoulder olf that lever. and it lends to turn the lever #l2 backuf'ardly on its pivot to suoli a position that the trigger l5 can co-act with the shoulder on the lever. The pmvhcarrving arm ell is provided with an opening- LS through which v extends a` stud Ll-) carried by theI poul Q7. Pivot-ally mounted upou the plvot-pin connecting the lmk with the pand-carrying;

arm lll. a locking* lever .30. A spring 5l44 is connected at one end to this lever and at the other end to the stud 49 and serves the double purpose oli' holding the pawl 27 `yieldingly in coaction with the. teeth of gear 26 and of holding the lever 5() yieldingly in the position in which it is shown in Figs. 9 and l2.- f lhen lever 5 0 is in this positiom' one end 'thereof is directly .in rear of the inner end of the lever 42 and serves to preclude movement of lever l2 in case trigger is accidentally displaced. The opposite end 53 of lever 50 extends adjacent to `the edge of the paivhcarrying arm 4l and -2 and 9. -lio e completed un moverse when lever 5() is in locking position this end 53 projects beyond the edge of the arm eil shown in Figs. 9 and l2, Lever 50 also provided, with a. lateral projection entering a slot in the persi-carrying irin il 7o to limit the movement o" lever f I rlhe movement ot 'the operating erm il .in one direction is limited by i stud .iflf projecting from the support l, this stud serving` to prevent overthrow of the oper-Ming arm as 7: the result of momentum. p "Vl/'hen i key is depressed, resulting in the forward movement ot the slide-bar lll the `link l5 and the pau/l carrying arm together with the parts moved thereby are carried around the pivot of wheel QG in :iccf` dence with the movement of link lo. il her ",.e is then operated to return the pawl-cerrying arm und the parts carried there-j to their initial position and. when these parts :nre moved thus, they turn wheel QG a distance corresponding to the value of the key depressed. lt it is necessary vto carry' one to 'the Wheel thus actuated, the trigier es is released and the lever l-Z is eauwd to turn about its pivot so as to cari;' v pir-vl forward and thus move wheel EEG one step lartlier, the lever 5t) being; rocked to mi lock lever 4-2- and permit this movement il the latter. rllhe lever 42 is prtwided with a lateral projection. at its reiir end adapted to be engaged by the inner :nd olf a lever 57 pivotelly mounted upon toe stud 28 and pressed by a` spring to turn it in. e eounter-clocl Wise direction er sof Jee t are not under tension, the sprl bearing upon studs on the convenience in assembling'.
