' To all whom it may concern:

Be it known that' I, THOMAS Cen'ilm', a citizen 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.

The object of the invention is to'p'i'ovide' a,

. cash register with an improved electrical mechanism, for automatically efi'ectin its operation, after certain elements have een properly set for such operation.

The invention consists of certain novel constructions, combination and arrangements of parts, all of which will be hereinafter more claimed. I

-The amount keys 13,'comprise suitably numbered heads and shanks, which latter of the key shanks, as shown in dotted lines ward end of its respective keylevfer'is cor'rein Fig.1. When a key is depressed, the forspondinglydepressed, and its rear end elevated to effect the coupling with the pivoted k'ey'coupler12.

As a numberof the parts shown in the same in construction, as the parts shown and aremounted in a supporting and guiding present application are substantially the described in the patent to Carney #583,888,

said atent may be referred to for a more detaie'd description of said parts.

naled inth'e frame of the machine by trunnions '12 and 12 and is arranged to co6pcrate ivitlr notches 18 formed in their re spective key levers, to couple. the levers for simultaneous operation. In order, however,

thatthe keysmay be operated successively, I

coupler to pass under the lower end of the Y 95 ,pawl 41. This action prevents the return of the lever, independently of the coupler. After the coup operation of the second key lever will cause its pawl 41 to engage the keycoupler, as said lever rises, and thus force ,the pawl back wardagainst the tension-of its s ring, so that, when it passes above the cou er flange 12, it will again spring forwar oven t e same and become coupled thereto.

- The key coupler is limited in its initial movement by a-stop nose 29, formed on a ivoted yoke 32, so as to nor mally project. into thepath of a pin '27, carried by an. arm

lar eia' tseeea all? theferk ";k y levels The aforesaid key coupling bar 12 is jour- 25 over the same as shown in Fig. 4.

the detents 43 is rovided, as before stated,

45 against the stop pin 78 by. a

18 and is held in its normal position by a coiled spring 32 which connects it with the stationary shaft 31 as shown in dotted line in .F 3. When one of the clerks key le- 5 vers is depressed the frame 32 is rocked and the nose 29 is moved out of-the path: of the pin 27, to permit the coupler to be operated.

The keys of this machine, as is usual in cash registers, are divided into a series of banks, and each of these banks is provided with one of a series of detent plates 43. These plates are ivotally mounted upon a rockshaft 42, an each-of the same is held in its normal position by a coil spring 45,

which connects it -with the stationary plate 13. (See Fig 1.) The lower edges of the plates 43 project into notches 44 formed in the key levers. \Vhen a key lever is given its finitial movement its. respective detent-43,

will be rocked slightly forward, .by the rear wall of the notch44, until the lever passes free of the dete-nt, when the latter will assume its normal positiom and lock the key lever in its depressed position, by passing One of foiueach bank 0 keys; but as the special keys 15 must be operated independently of the regular 'keys, they are each provided with an independent detent, as clearly shown in Fig. 1..

The detents are rocked forward, to permit theoperated key levers to return to their normal positions, by a series of pins 7 5, fast .on the shaft 42, and arranged to engage the upper edges of the plates 43, as plainly shown in Fig 4. The shaft is rocked near the end of the operation of the machine, by an arm .73 which is fast thereto, and which 40 is engaged and operated by a cam 74, fast on a transverse rotation shaft 37. This shaft is given one rotation during each. operation of the machine as hereinafter described. The lever '4' 3 is held in its normal position coil spring 76 which connects an arm 73 thereof with a pin 77 on the main frame (sedFig. 4).

As it is desirable to prevent the operation of any one of the clerks keys until after one 0 of the amount keys, or one ofthe special keys has been operated, each of the clerkswith a stop pin 2(3- key levers is provided best shown in Fig. 5. These pins are normally engaged by, hook arms 25, mounted on 5 a sleeve 23 fastto a-trans'verse rock shaft 24.

This shaft also carries a series of cam arms 22, which pro ect upward in proximity to each of the amount keys and special keys.

These cam arms engage pins 21, projecting from the amount and special key levers so as to be rocked thereby.

It will be seen from the above that, when one of the amount or special key levers is operated, the shaft 2-4 will be rocked rearward and thus disengage arms 2-5, from pins ment of the shaft o 26, to'release all-of the clerkskeys. The latching arms and cam arms are returned to their normal positions by a suitable. coil spring 22 which connects one of said arms with the main frame.

Each of the key levers 18, except those of the special keys 15. is formed with a cam slot 20. These slots of each bank are of graduated formation relative to a bar 20 of the registering frame 20* with which they coiiperate, as shown in Fig.

The pivoted, registering frames 20*, carry suitable rack segments and are. mounted above the respective key banks. Each of these frames is provided with a cross bar 20 which when a key lever is operated, is engaged by the walls of the cam slot of said key and. the frame 20; thus rocked to a greater or less degree, accordingto the value of the key operated.

The operating rack segments carried by the registering frames'coiiperate with the pinions of the counter wheels, to impart movement thereto, in a manner well known in the art, and described in the aforesaid patent.

The tablet indicators 10 are mounted to coiiperate with the rear ends of the key lcvcrs substantially as described in the said patent. r

The oscillatory movementof the key coupler 12, is cimvertcd into rotary move- 35. This bar is formed with a horizontal slot 34, into which projects a pin 33 mounted on the arm 28' By this means. the bar 35 is raised and lowered with the key coupler. At its lower end. the bar is formed with a vertical slot 35, through which projects a guiding and fulcrum pin 35 mounted on the main frame. The opposite edges of the upper'portion of the bar are formed with rby means of a rack bar rack teeth which are adapted to alternately I engage and operate pinions 3G and 38. These )inions are connected, at one side of the rack bar, by an intermediate pinion 40 whereby the pinion 36 is continuously rotated in the same direction, even though the pinion 38 travels in an oppbsite'direction when rotated. The rack bar is held to its work by a lug 40 which plays on one or the other side of a stationary, vertical flange 40 formed on the main frame. A spring 39 is connccted to the lower end of the plate 35, and isso arranged, that it exerts lts tension keys andkey levers are separate as shown ,in-theaforesaid patent.

' After the amount keys and special keys have been coupled to the key coupler, it is 5 necessary to oscillate the latter, in order to complete the operation of the machine. -T o {effect-fins result, the depression of one of the clerks keys establishes an electric circuiwthrough the motor 17, which 'is geared tothe key" coupler, as hereinafter described.

To accomplish the closing of the electric kircuit, each clerks key lever is )rovided with a pin 46-, which engages one oia series of cam arms 48 to rock the shaft 49 upon which the said arms are mounted. Eacli of the cam arms is formed with a camedge i 47 and a concentric edge 48, whereby, when a key leveris operated, the arm 48 will move only when the pin 46 is engaging the edge 47. During the time that the pin is passing over the edge 48, the arm 48 remains stationary for a purpose hereinafter described. Thespring 48" wound about the shaft 49 is connected with the main frame, and to one of the arms 48 so as to normally hold the" arms 48 in the position shown in Fig. 3. The

left end of the shaft 49 is provided with a crank 50lto which is pivotally connected it ndent link51 having a cam nose 52 and a SOmotched end 53. The spring 50 is wound ;about the pivot of the link 51, and bears with its respective ends against the link and the .arm 50. The office of this spring is to hold the link 51 against a stationary .-'top pin 57. The lower; notched end 53 of the link 51 engages a pin 53" which connects a pivoted bell crank lever 68, and a link The link 55 is in its turn connected with a switch lever 56 which is pivoted to one of the circuit terminals 56 of the switch. The contact terminal 56 of the switch. is of the usual splitspring construction, and is arrangedto receive the contact lever 56 whe'ii the latter is depressed, and thus complete the circuit. 15 When one of the clerks ke s is given its initial movement its particu ar arm 48 is rocked forward and the shaft '49 rocked.

This action forces tlhe link 51 downward and as before descr bed, closes the'circult through the motor which operates the machine, as described. As the key lever continues its downward movement, the pin 46,

simply lays along the edge 48, of the arm -l-8 and t illS holdsthe link 51 de rcssed, until the key lever is subsequently re cased, by the rocking of its dctent 43. The first downward movement of the link 51 forces the arm 56 to'engage' the contact terminal56". As'

the link 51 continues its downward move- 60 ment, the cam 52, engages, the pin '57 and moves the link out of en agement with the pin 53. This leavesthe ink 55 free to rise and break the circuit, before the link 51 is allowed to return to its normal position. .65 This construction prevents apyvtnanipultition of the machine, such as an attempt to depress the link 51, the second time, during the same'operationof the machine, and also permits the necessary sequence OfOPG IM-IOD.

One of the projecting trunnion ends of the key coupler is providedwith a crank arm 67 carrying an anti friction roller 66. ThlS roller is engaged by'cam 63., mounted upon a short rotation shaft 61, which 'latter is journaled in the main frame, and in.an auir- 'iliary frame 62. The shaft 61 carries a worm wheel 60 which meshes with a worm 58, fast to the armature shaft 59 of the motor. The shaft 61 also carries a stop lug 65 t and a cam 64, The bell crank 68 is formed so with ail-auxiliary arm 70 carrying a roller- 71, and is also formed with a hook 72. This hook is adapted to normally project into the path of the lug 65, to arrest the mechanism 111 its normal position. \Vhen the link 51 is depressed} thehook 7 2 is moved out of the path of the lug 65, thus leaving the shaft 61 free to be rotated; This same movement of the, bell crank brings the roller 71 into the path of the cam 64 whereby, when the an operation is about half completed, with the key coupler-raised, the lever 68 will be rocked to draw the contact lever 56 out of connection with the contact 56", and break the circuit. The momentum of the armature, howas ever, is sufiicient to carry the parts forward, after the circuit is broken, until the lug 65 'contacts with the hook 7-2, when the parts areall arrested. The'key coupler and key lovers are returned to normal posit-ion by 160 gravity or if desired, suitable springs 12 may be employed to assist in the return movement. I

. The motor employed in this machine may be of any suitable construction and opera- 10.3 tion, and, as such construction forms no part of the present inv ntion it is not thought necessary-to describe it. v

The operation 'of the machine is as follows: If :1 sale of $5.50 is made by clerk A, the amouiit keys are first pressed and then the clerks keyA; ,T he depression of the amount keys causes their respective key .levcrs to become coupled to the key coupler.

\Yhcn the clerk's key is'depressed, its par-' ticul'ar key lever becomes coupled to the key coupler and the circuit is closed by the depression of the contact lever 56. This operation also releases the machine by moving I the hook nose 72 out-of the path of the lug 65. The operation of the motor then causes the worm 58 to rotate the worm wheel 60,- and thus elevate the coupler by means of the cam 63 connected to said worm wheel. After the coupler has been fully elevated, the cam 63 passes free of the roller 66 andgthu's leaves thecoupler'free to descend by gr vity.

At the same time the circuit is broker but the momentum of the different parts carries the worm wheel 60 forward until it is ar- 13 0 rested in its normal position by the lug 65 comingdnto contact with the hook 72.

By means of the peculiar Worm and worm gear connection it is practicable to employ whigh speed motor and at the same time only operate the machine with a medium speed and not fast. enough to rack or jerk the arts during the operations .By' this rapi movement of the motor and relatively i machine subsequently operated by hand.
