THOMAS MIDGLEY, JR., OF WORTHINGTON, OHO, ASSIGNOR TO THE NATIONAL CASH REGISTER COMPANY, OF DAYTON, .OH-IO, A CORPORATION OF OHIO, (INCORPORATED4 Be it known-that I, THMAS MInGLEY, Jr., a citizen of the United States, residing at lVort-hington, in :the county of Franklin and State `of Ohio, have invented certain new and useful Improvements in Transfer Mechanism, of which I-ideclare 'the' following to ber a full, clear, and exact description.

This inventionv relates to accountingsmachines and more particularly to the transfer devices for the registering'l mechanism thereof. i

The yprincipal obj ect of this 'invention is to 'provide a transfer. mechanism? which lis simple and Vdurable inits constructionypositive in its` operation Land accomplishes Atransfers at the'exactmoment'the'y becomenecessary, regardless-wf Whether the ldenominational elements of the y.registeringmechi'inism are in rotation :or not.: -zInthe preferred form shown 4herein transfers vare `accomplished Without moving'fathe actuators an additional step. Py accomplishing transfers at the exact moments-that they are required during movement of the actuating mechanism, considerable time is saved, as no time whatever need` be. given for the transferring operations. The saving of time is of considerableimporta-nce in highly developed machines provided with registering mecha nism, as these are often designed to accomplish many different functions, and care must bc taken so that the properV time is given for the attainment of each function. Therefore, a mechanism which accomplishes this object of applicants invention is a decided improvement over many prior trans fer mechanisms in which an extra step of movement is imparted to the registering'ele- .ments by the actuating mechanism or other means after the actuating mechanism has been moved. an lextent determinedv by the amount manipulative means controlling the actuating mechanism, as with transfer mechanism of this latter type, considerable time is required for the transferring operation. A positive transfer mechanism suchas dis closed. in. the preferred form of embodiment shown in the drawings is certain and' minimizes the lial'iility of Vthe mechanical troubles existing in transfer mechanisms in which the transfers are effected by spring action.

For convenience of illustration the present invention is .shownin connection lwith the form of key operated differential mech- '.ina'irfrsi;En MECnANIsM.

which has been shown and described 1n U. S. Letters Patent-No. 97,86% granted Itl will be obvious, however, fromthis specification and the. accompanying drawings thatthe present transfer mechanism can be equally well enr. ployed 'in any type of cash register or registering machine, Whether it be a key operated machine 'or a .two motion machine, that is, a machine in which the operation of the keys predetermine.` the extent of rotation which is to beimparted to the registering Wheels by; the. actuators while the actuators are driven byfsu'bsequent.,operation of the operating mechanism. It is, therefore, not desired to limit this invention to any pa1. ticula-r embodiment, the claims .being in# tendedtodefine the transfer mechanism,.and not the actuating devices except in'combination.. l WVith .these .and incidental objects. 4 in view, the inventionconsists in certain novel fear turesof construction and combinations of parts, the essential elements of which are set forth in appended claims, and a preferred form of embodiment of which is hereinafter described. ,with ,reference to the drawings .which .accompany and form part of' the specification Figure l is a central transverse sectional vieu' of the type of machine shown and described in the aforesaid Letters Patent with this invention. applied thereto.

I

Referring 'toFig 1 of the drawi11'g"s,`the operating means for act'u'atingV Vthe'act'uatin'g mechanism for' the totalize'r comprises the keys 1 pivoted on 'a 'transverse' rod '2 which is supported by`thefsid'e'frames` 3 o'fj tl'emachine. These 'keys' have ibosely' Vattached neartheir rear ends 'uprigh'ts which Iare graduated as is well known in tliela'rt and fully' describedV and shown. in the before mentioned patient.' The uppere'xids of'the uprights 4 are 'cammed forW-ard'asthe'keys are depressed b curved 'surfaces 5,' formed upon the rear e ge ofeach of 'the upi'g'lhtsll, coming in contact with a tie'bar 6 supported by the side frames 3 'ofthenachine. i Aisthe upper ends of ithe uprights 4 move Iforwardly they 'contact with transverse 4rods 7 carried by lockingpawls 8 I11-nd"`ro1k'th'e upper ends of said "pawls out of 'lockingenA gageme'nt with a latchor fflange"9for1``ied upon the 'upper forward edgeof thetie bai` 6. These pawls 8 are Apivoted attheir lower endsupoii transverse rod's10 which aire supported by rearwardly extending-arms 12 of actl'l'atingrames cach of which comprises two arms '12 and a bar 13 connecting the 'arms'12, each l'(` f"\vh1ch arms 12 are" suitably supported by' 'a transverse shaft 14 suitably secured in ,the side frames 3 of th'e'inacliine. Itis to 'be' understood that the keys 1 are arran ed in banks and for eac-li key bank therel'ison of these actuating frames carrying-a transversel rod, 10 and locking pau-'1s 8 which in turn carry a rod 7. Spring means (not shown) are -providedmto force the pawlsSfinto lockin'gjposit-ion as shown in Fig. 1 in order' to prevent any accidental displacement of the registering fra-nies.

Each of'these registering frames is provided '.'Withf ari-actuating segment gear 16 which. is 'fast to .one of the arms 12 and loosely: *mounted onr the shaft 14; Each actuating segment gear 1G as shown in'Figs. 2 and 3 meshes iwith a' corresponding transfer wheel 17 'which :is provided with teeth or threads 18 each of which forms an obtuse angle and the vertex ofv the angle points in the direotion'of movement of a wheel during rotationwo'thetotalizer' wheels. Each transfer-wheel-H is mounted to rotate freely on a corresponding drum 19 which is loosely mounted upon a collar orenlarged portion 20 (Figs.c6:and'7f) on a stationary rod or shaft'21- Which ,is carried by the side frames 3 of the-machine Each transfer wheel 17 isv prevented frommoving-'axially in one direction 7relative to its drum 19 by a plate 22 fastto the'drum 19 and in the other direction by an enlarged portion 23 of the drum. The totalizer wheels 24 are fast 'to sleeves (Figs. 4, 5 and 6) which have a rotating movement upon the shaft 26. Sleeves 2K3 (Fig. 6) surrounding the shaft 26 prevents movement of the totalizer wheels longitudinally-of tl1esliaft26- The shaft 2G is supported atv the outer ends by two for.- ward'ly and upwardly extending arms 27 of the totalizer-frame- Each of these armsl form part'of levels 28 loosely mounted upon a shaft 29 secured to the frame work of the machine.

' The pinions'24 are normally out of mesh witlrthe -teeth 18 of the'transfer wheel 17 and arerocked .into engagement Lby cams 30 (Fig-2) secured tothe rotation shaft 31, upon the beginning of movement of any ofthe keys 1. The rearwardly extending` arms 32 `ofthe levers 28 comprising part of tl1e""totali'zer frame are bifurcated and each prong 33' of the bifurcated portion lis provided with an anti-friction roller 34 with which a cam 30 engages. But one of these cams 30 is shown but it wili be understood that a' similarcam is provided to rock the f lever' 28 vat the opposite end of the totalizer frame. It will be seen from this figure that theirst movement of the cams 30 which is inthe direction of the arrow rocks the totalizer frame about its pivotal point 29 so as to carry the pinions 24 into engagement with' the transfer wheels 1.7 so that a continued downward movement of the operated key or keys 1 will cause the uprights 4 to engage with the transverse bars 10 of the actuating frames and in this manner cause the actuating seg-ments 16 to rotate the transfer wheels 17 and thereby the totalizer pinions 24 extents determined by the value of the 'keys depressed It will be seen in Fig.' 3 that the units totalizer pinion 24 at the right of the figure is adapted to engage with the broad gear wheel 17"L which is loo'sely mounted on the stationary shaft 21 and is constantly engaged with the actuatingr segment 16 operated by the units or cents keys 1. The threads of this wheel are parallel with the axis of the shaft and do not form angles as do the threads of the transfer wheels for the totalizer pinions of higher order as there is no totalizer pinion of lower order from which one is to be carried.

The rotation shaft 31 as shown in Fig. 1 is provided with a pinion 36 which engages a two-faced rack pla-te 37. This rack plate is provided with a slot 38 into which projects a lug 39 projecting from a key coupler or universal bar 40 common to the keys 1,

as is well-known in the art. From this description it will be seen that when the keys 1 are depressed`the rack plate 37 will be elevated and theshaft 31 rotated in a clockwise direction as viewed in Figs. 1 and 2. At the end of the downward movement of the operated key a spring 41 under tension between the rack bar and a pin 42 fast to the frame work at the back of the machine will shift the rack plate 37 so that the teeth formed on the forward side of this plate will engage the pinion 36.y and as the rack plate is lowered by the return of the key to normal position it will continue the rotation of the shaft 31, it being understood that the rack plate 37 is suitably guided by a plate projecting from one of the side frames 3 so that the one side or the other of the twoface rack plates will always be in engagement with the pinion 36.

Fast to the sleeves 25 on which the totalizer pinions 24 are rigidly mounted are transfer disks 44 each of which carries a pin or stud 45 projecting from its left hand face. The periphery of each of these transfer disks is provided with a semi-circular cut or recess 46 and the radius of the disk which passes through the stud 45 also passes into this cut. iWhen the totalizer pinions are rocked into mesh with the transfer wheels 17 the periphery of each of the transfer disks 44 is carried into Contact with a stud 47 projecting laterally from the base of a nearly circular disk 48 fast to the right hand side of the drum 19 carrying the transfer wheel 17 which meshes with the totalizer pinion of next higher denomination. The circular portion of this disk is'just flush with the periphery of the enlarged portion 23 of the drum 19 and carries two projecting portions 43 and 49.

A rod 50 (Fics. 1 and 2) which is carried at the outer end of the upwardly extending arms of two levers 51 loosely mounted near the ends of the stationary shaft 21, normally engages the radial face of the projection 43 on the disk 48. The lower ends of the levers 51 are provided with slots 52 through which pins 53 -projecting from the upper ends of levers 54 pass. The levers 54 are loosely mounted upon the shaft 29and at their lower ends are connected by pins 55 to pitmen 56. at their rear ends andA straddle the rotating shaft 31 and the pitmen also carry rollers 57 which play in cam grooves 58 formed in the faces of disks 59 rigidly mounted on the rotating shaft 31. The configuration of the cam grooves 58 is such that at the be inning of the downstroke of the operating' ey the pitmen 56 will be drawn rearward to rock the levers 54 clockwise and the levers 51 counter clockwise and thereby carry the rod 50 out of normal engagement with the projections 43 on the disks 48 as shown in Fig. 5.

After a- `totalizer pinion has been moved nine steps from zero position, the relieving cut 46 of the transfer disk 44 is brought opposi te the stud 47 on the disk 48 and at the same time the stud 45 on the transfer disk 44 engages the projection 49 on the disk and thereby rotates the drum 19 carrying the transfer wheel 17 of next higher denomination a slight distance in the direction in which the transfer wheel is being rotated, that is, counter-clockwise, and as the totalizer pinion passes the zero position it passes out of engagement with the projection 49. As shown in Figs. 3 and 7 each drum 23 carries a pin 61 rigidly and radially seated in its enlarged portion 23. The inner end of the pin 61 projects beyond the internal periphery of the drum 19 into a curved groove or slot 62 in the enlarged portion 20 of the shaft 21. This cam groove or slot 62 is so constructed that when the drum 19 is given a movement relative to the shaft 21 by the engagement of the pin 45 with the projection 49 on the disk 48 the drum 19 and therefore the transfer wheel 17 are moved to the left and longitudinally on the stationary'shaft 21. As shown in Fig. 3 the actuating segment gears 16 engage the threads 18 of its transfer wheel 17 immediately to the Tight of the vertices of the angles formed by the threads so that when a transfer wheel is shifted to the left `with its drum it will be advanced 4 a step of movement ahead of its actuating segment gear 16 i-f the latter 1s moving or moved The pitmen 56 are bifurcated l.Again referring-to Fig. 3, it willbe seen that each 4totalizerwpinion engages the .wheels depends threads 18..-.near the left-.hand side of its transfer Wheels so that Whentheaxialf movement of .thetransfer Wheel to the. left .is

effected the totalizer--Wheel will'be driven b a -stepahead of =the 1transferwheel. As the transfer wheel has beensmoved l5-a step .ahead of--the actuating segment -16 and the -totalizen pinion has.- beenmoved astep aheadlof the :transfer-Wheel 17 it-can `readily :bel-seen. that the totalizer wheel will be moved one step..ahead of: the actuating seg- -ment gears l'to'effect the. required transfer. Of course, .the eXtento-f fected by the lateral shifting ofI the transfer on the inclination of the teeth'on these .Wheels tothe' axis'of the shaft, Vbut thisV linclination is made such. .as .to,' in the operation'just describedgimpart in. total 'anextra step1 of movement to thetotalizer E pinion when the Atransfer"Wheel-.is..shifted back to normal laterally:

On the: upstroke of the key 1 which has been operated, the rod 50 Will 'be Arocked positionby the cams 58 and during this movement it will engage the radial :faces ofthe projections 43 `on the disks 48 of thedrums 191 which havevbeen =dis placed longitudinally of the shaft 21,.'and will carry .the drums and ltransfer Wheels back to normal position. It will be apparent that thisumovementof the rod 50 will move lthe transfer` wheels and :drums which have been. displaced back to their normal positions through the. Acooperation of the cam grooves 62 With the pins 61. Springs 65, one foreach,- transfer-Wheel,.are coiled about the. st tionary shaft 21 to the right of the.drums 19 and .one end of the springs are bent about the projections 43 on Vthe disks 48 AWhile their opposite ends .are fastened to studs- 66 projected from the stationary shaft 21, as best. shown in Fig. 3.

It -is thought that the description given above -sufliciently sets forth the -pr-inciple -and mode. of .operation lof the .presentinvention. It is fcleafr that. eachl transfer device consists of atransfer--Wheel 17, a drum 19 and .connections between .the drum and its .supporting shaft whereby -thedrum and transfer'wheel are shifted longitudinally on the shaft. This longitudinal movement-is accomplished; positively.' by the.. transfer pinion of nextlovver denomination-and the- .wheels .upon
