CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 428,270, dated May 20, 1890.

Application filed February 8, 1890.

-To all whom it may concern:

Be it known that I, THOMAS CARNEY,'1'6- siding at Chicago, in the count-y of Cook and State of Illinois, and a citizenof the United '5 States-have invented a new and useful'l-mproveinent in Cash-Registers, of which the following is a specification, reference being had to the accompanying drawings, in whicl L'- xo at line2 of Fig. 1. Fig. 3 is a detail, being a partial section at the same line as Fig. Fig. 4 is a section at line i 4 of Fig. 1, the spring at one end. vof the pa\vl'-bar I being omitted. v

The objects of. my invention are to provide anim proved key-arrester to provideimproved devices. for locking all of the keys, except those which are being operated; to provide devices, by means of'which, when the'key's which are notbein g operated have been locked and the'drawer opened, such locked keys will 'remain locked until the drawer has been closed, and be unlocked by the closing of the ,drawer,-all ofwhich I accomplish, as illus- 2 5 trated in the drawings, and as hereinafterde scribed.

That which I claim as new, and desire to secure by Letters Patent, will be pointed out in the claims.

[3.0 In the drawings,Arepresents ametal frame, in which the working parts of the machine. are supported, as usual.

B is a series of keys, pivoted on a shaft 0, as usual. 1

D is the so-callcd bell-bar, the ends of which are secured to arms a, which are pivoted on a shaft E, as usual. I

F are levers, one for each key. The forward end of each lever is connected loosely 40 with the rear end of one of the keys, and the rear end of each lever is pivoted on the shaft -E. Each lever F. is, as shown,-provided with a projection l), arranged to engage with a hell-bar D.

G are springsone for each lever F. On each key there is a plate H, which, as shown, is integral with the key.

surrounded with rubber, which rod serves the c are teeth and notches on the upper edge of each plate. A portion (2 of theuppercdge r Serial No. 339,748- (No model.)

of each plate, near the inner end thereof, is go not provided with notches, but is smooth.

eis a tooth at the end of each plate. p f is a'si'nooth snrfaceon the upper edge of each. plate near the key. V I is a bar pivoted at its ends in theframe,

- which bar serves the purpose of a pawl for all the keys, and may be called a pawl-bar. Figurel 1s a plan. Fig. 2 is a cross-section The upper part 9 ofthis bar is fiat. The lower side h of this bar is narrow, and is provided, as shown, with two angular edges ij.

k are two springs arranged to act on the aWLbarI. These springs hold the bar Lin its normal position (shown in Fig.2) whenthe' keys are ateither end of the stroke, and when a k cy is being pulled forward these springs hold the edge 1' of the bar I in engagement with the notches c, as shownin Fig. 3, and when a key, having been operated, is returning to its normal position the springs hold the edge j of the bar I in engagement with the notches c, as shown in Fig. 4. l

J- is another pawl-bar pivoted in the frame, which pawl-bar is arranged to engage with the teeth e on the several'plates H.

Z is a spring arranged to'hold the pawl-bar J out of engagement with'the teeth (2.

K is a short standard connected with the bell-bar 13'. The upperedgc of this standard is fiat and the front edge is curved.

L is a lever pivoted at in. One end of this lever is arranged to engage with the top and front edge of the standard K, and the other end engages With the pawl-bar .l.

M is a rod secured in the ends of the frame 5 pnrpose'of a stop when the keys return to their normal position after having been operated.

The operation of the parts of my invention already described is as follows: When the keys are in their normal position, the pawlbar I will be in the position represented in Fig. 2. If one ofthe keys be pulled forward, the teeth 0 will engage with the edge '1'- on the pawl-bar I, causing it to assume the position shown in'Fig. 3, and then the springs It will have a tendency to hold such pawl-bar in that position which prevcntstho key from return- H Al ing or being returned to or toward its llttl' mal position until after it has complct ed its fullstrokc, at which time the lower part of the'bar I will come to the smooth part i! on the plate II, and when the key returns to its normal position the teeth 0 will engage with the edge jot the pawl-bar I, which will come into the position shown in Fig. :i', and then the springs 7; will have a tendency to hold such cdgej in engagement with the teeth and notches c, which will prevent the key from being moved in the opposite direction until after .it has completed the return movement. When either one of the keys I) is pulled for- .ward, the bell-bar D is immediately raised through the operation of the proper lever F, which causes the front edge of the standard K; to pass over the rear end of the lever L, liftingsuch end, and thereby depressing the opposite end, which, being in contact with the pawl-bar J ,'forces such bar down into engagement with the teeth c on all of the keys which are not being operated, thereby locking all of such keys.

.I will now describe devices, by means of.

.' which the keys when looked, as above stated,

are held locked until .of the drawer. N is a' money-drawer, which, as shown in 1 Fig. 4, is supposed to be open. This drawer runs on rollers.

O is a rod secured to the rear end of the drawer, which rod passes between two rollers pivoted to the standard I; The devices for holding the drawer locked and for unlocking I the same are not shown, being no part of this invention. Q is a lever pivoted at its upper end to the 5 frame. n is an arm which extends forwardf from the lower end of this lever Q, with the forward end of which arm the rear end of the drawer ll comes in contact when it is closed. f The upperend of the lever Q is cut away, so 5 that there is a notch p in such lever. 'q is an arm or bar secured to the bell-bar? D, the forward end 0' of which arm is bent at-i right'angles and engages with the front edge of the lever Q. f S is a spring-arranged to act on the lever Q. When one of the keys is operated, the bellbar will be raised by the action of the proper lever F, which will carry the arm q upward until the part r of such arm passes into the notch ;v in the lever Q, the lever L being at. the same time operated upon, as before described, forcing the pawl-bar J into engage-' nent with thetceth e on the plates II of the keys which are not being operated. So long as the arm or bar q remains in engagement with the notch the bell-bar will be held in its raised position, (indicated by dotted lines in' Fig. 4,) which will hold the lever L in engagement with the pawl-bar J, in which position the locked keys cannot be .operated.

released by the closing 'lhrdrawer N is supposed to have been openedat.thepriiipertime. ,\'henthedra\\-i-i is closed, its rear end will engage with thitorward end oi the arm non theleverQ, t'oning the lever back and releasing the tmwvard end 2' oi the arm (1 from the notch p, wlu-n the bell-bar will return to its normal position. releasing the lever L and pawl-bar J, and then any of the keys which were locked (:in be operated.
