To all whom it may cmwemf Be it known that I,} EDMUND SlCHURCH, acitizen of the United States, residing at Dayton, in-the county of Montgomery and State of. Ohio, have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to be a full, clear, and exact description. I

This invention relates to cash registers and has for its object to improve the construction of that type of machine knownas the multiple register. By this term is meant one in which transactions are adapted to be entered in the machine in segregated groups. v

The invention includes a plurality of accounting devices which may be registers 0r sets of printing wheels or separate mechaadapted to be positioned directly by a manipulativedevice such as a lever and such positioning consumes valuable time. p The resent invention improves this construction y providing a series of keyswhich when depressed serve to determine the positioning of such a reel, the actual work of such positioning being performed by a main op-' erating device such as 'a handle or crank lever or cash drawer.

With these and incidental objects View, the invention consists in certain novel fea tures of construction and combination of arts, the essential elements of which are set orth in appended claims and a preferred form of embodiment of which is hereinafter specifically described with reference to the drawings which accompany and form part of this specification.

Of said drawings: Figure 1' isa side elevation of the machine to which these improvements are applied. Fig. 2 is a transverse vertical section .through the machine Application filed September 10, 1906. Serial No. 333,950.

carriage to a desired position.

takenjust inside of the sideYframe, and

Fig; 3iis a partial rear view ofthe machine. The present inventionis designed to furnislr means for quickly and accurately setting any one of a plurality of accounting devices for operation by a common operating mechanism. In the present improvement the. ccounting devices are shown as counters mounted 'on' a rotatable carriage. Connected to'this carriagethrough gearing are a plurality of helically arranged heart cams which are ada ted to be separately engaged by a movable element to brin the Such eart cams are widely used to reset clocksand are used herein in a very similar way except thata plurality of them areprovided displaced angularly around" a common shaftso that the whole system may be set at any one of a plurality of positions. A series of'keys is used to determine the. positioning of the carriage such keys, when depressed being .in the path of a ever which serves to position the movable lement before referred to in the plane of any desired heart cam. The

mechanism'describedserves to takeall the work of positioning the carr age from the keys or levers and put it on the main oper-' ating device.- I

The type of machine to which these imlpioveme'nts are shown as applied isnow well own in the art being. fully shown and described in Letters'Pat'e nt to Thos. Carroll No. 654,226 dated July 24, 1900 and No. 703,639 dated July 1 1902, but it is to be understood that the invention is equally" as well adaptedto be applied to other types of machine.

Keys 10 are slidably mounted in the framework of the machine and on their outer ends 'bear characters representing .diiferent clerks, departments or classes of transactions. When any of these keys is depressed. it sets the mechanism shown in a position such that upon the operation of the machine I one of the counters (or ,sets of printing wheels) 35 corresponding to the keys 10 depressed will be brought into a position .to be operated upon by mechanism fullyshow'n and describedin the above mentioned patents. This operating mechanism comprises a series of segment racks 36, having connections to the main operating devices of the O p 25, secured to the sleeve 15, to operate said vices or counters may upon an be recor carrying evices.

. mal outer position an key bearing a pin which is mounted on a camming On reference to Fig. 2 it will be seen that the keys 10 are spring ressed to their nor are provided with laterally projectin pins 11 which (see Fig. 3) are of different lengths. When one of the keys 10 is depressed it is latched inits op-. erated position by a detent (shown in the above mentioned patents). v

Pivoted at 12 on the framework of the machine is a lever 13 having a sector sha ed forward end 14 which spans all of the ey pins 11 but which is not ofgreat enough extent to strike any of the sai pins unless the has been depressed. The lever 13 is normally held out of 'enga ement with the key pins 11 by a camming ug 20 disk 21 and cooperates with a pin 22 mounted on said lever 13. I

-The rear'end of "the lever 13 is so formed as to straddle'a sleeve -15 mounted on a shaft 16. On said sleeve is mounted a collar 17 between which and a stationary standard 18 is interposed a spring 19 which normally tends to force the collar 17 in the direction of the arrow in Fig. 3.

From the above description of the mech-' anism it will be plainly seen that when a key 10 is depressed one of the key pins 11 is brought into the path of the sector shaped end 14 of the lever 13 thereby forming a stop against. which said lever abuts, when released by mechanism to be later described. When the lever 13 is released the Spring 19 will forcethe sleeve 15 to the right in Fig. 3,

a distance depending upon the key depressed until it is stopped by the pin 11 of the de-' pressed key.

Pivoted at 23 on the framework of the machine and extending rearward is a lever 24 the end of which cooperates with an arm on the shaft 28 and is rocked'through the arms 29 and link 30 by the shaft 32 which revolves in the direction of the arrow in Fig.2.

cams.

and the position ofithe cammin lug 20 it will be "clear that the lug 20 Wlll first be moved out of the path of the pin 22 to release the lever 13 and allow spring 19 to set the sleeve 15 in adesired posit on corresponding to the key 10- depressed, after which the lever 24 will .be cammed downward to rock the sleeve 15.

On the outer end of the'sleeve 15 is secured a spring drawn .cammin arm 40 which is rovided with a V lti'gidly secured to a sleeve 42 mounted on a shaft 43 is a set of nine heart cams 44 equally spaced around said sleeve, this being equal to a 40 pitch. I

Referrin to Fig. 3 it will be seen that when the s eeve 15 is moved to the right it will position the camming arm 40 directly in line with one of the heart cams and when arm 40 is operated as before explained the.

operating face thereof will contact with the periphery of one of said cams and rotate it until said operating face 41 cooperates with a V shaped alimng notch 45 of said cam, thereby'positioning the desired counter or other accounting device for operation.

It will be noticed that the greatest possible degree of movement of the sleeve 42 is 4/9 of arotation in either direction.

Agear wheel 46 is rigidly secured to the sleeve 42 and meshes with an idler 47 which in turn meshes with another gear wheel 48. The gear 48 is mounted upon a drum 49 which carries on its periphery ninecounters '35 and thus it will be clearly understood that when the sleeve 42 is movedto any one of its nine positions it will through the gears 46-.47 and 48 rotate the drum 49 to bring a correspondingcounter into operating position.

The operation of the machine is as follows: The desired key 10 is' depressed and the handle or other actuating device on the key is depressedit is locked in position and remains so during theoperation of the handle, such depression carrying the key pin 11 into the path ofthe sector 14. Whenshaft 32 starts to rotate the cam 21 begins to oscillate, and the cainming lug 20 is thereby carried away from the pin 22 on lever 13.- 0 This lever therefore moves "under the tension of spring 19 until the sector'14 abuts shape operating face 41.

shaft 32 is given a complete rotation. When I the key pin 11 of a depressed key thereby carrying the sleeve 16 and operatin arm 40 intoregister with one of the setio heart Further oscillation of cam 21 serves to depress lever 24 thereby rocking arm 25 which as stated is rigidly connected to the operating arm ;40. Such rocking causes the V shaped end 41 of the operating arm to engage one of the heart cams and move the same until its notch 45 is brought to contact Y with the t 4 7 From the shape of the camming d opera lng arm As the counter carnage is connected rigtion through the shorter of two idly to the system of cams the said carriage is thereby also positioned with a desired counter in the proper place for its operation. When the cam 21 is reversely oscillated it releases lever 24 which therefore rises allowing arm 40 to be withdrawn from the heart cam. WVhen cam 21 nears its normal position the camming lug 20 strikes the pin 22 on lever 13 and resets the same against the tension of spring 19. The depressed key' is also released and returns to normal position under the tension of its spring. It will be seen that the carriage and heart cams have no normal position to which they are returned at each operation. The system remains in the position to which it has been adjusted until it is desired to set it to some new'position and it will be clear that in no case will it be necessary to rotate the reel more than 4/9 of a circle or 160 for the reason that the heart cams will in every case move the carriage toward the desirl'pd posipat s.

The invention is not limited to the number of counters used because the mechanism described is evidently adapted to be used in connection with any number of counters, by

'merely changing the number and angular difference of osition of the heart cams.
