CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 361,802, dated April 26, 1887.

Application filed March 27, 1886. Serial No. 196,838. (Modehl T at whom, it 11mg concern.-

Be it known that I, PHILIP .YoE, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented a certain new and useful Improvement in Cash-Registers; and I do hereby declare thatthe following is a full, clear, and exact description'of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in cash-registers, the several features of which will be fully hereinafter set forth.

The mechanism is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the cash-register. Fig. 2 is a front-elevation of the same.

A is the base, to which may be attached a suitable form of case, the only requisite being that orifices must be provided in the case, through which may be seen the figures on the two wheels on which numerals are impressed.

Bis the metallic frame of the machine, which is alike on both sides,with the exception of the arresting-arm H,which is on the near side.

O and O are shafts, which are fixedly held in the posts of the frame and are secured by screws. On the shaft 0 is supported the computation-wheel D, on which it freely turns.

On the peripheral face of this wheel is a spiral rib, 0, which forms a continuous groove over the peripheral face of said wheel. This groove is uniformly spaced and numbered to suit different kinds of business. For a cigar-store the numbers may be 5, 10, 15, 850., and for other purposes the units would be marked. The ratchet-wheel E is fixedly attached to the hub of the wheel D,with an intervening space between the two. The teeth on this ratchetwheel correspond exactly with the numbered spaces on the computation-wheel D. Coven ing the lower portion of the peripheral face of this wheel is the shield L, in which is supported the slide N ,which has an opening near the right end,thr ough which a number on the computation-wheel D may be seen. This slide has areal-ward projection, s, which enters the groove of the computation-wheel, and which (as the machine is operated) causes the slide to move from right to left across the face of said computation-wheel, and thereby exposes a number successively as the machine is rotated. On the shaft O,external to the ratchetwheel, is the arm I,whioh carries a series of push-buttons, 5, l0, and 15, which can be pressed through openings in the arm I to engage the arm H, but are normally held, as shown in Fig. 2, by coiled springs. To a lug of this arm is pivoted the pawl-lever P,which engages the ratchet-wheel E, and the opposite end lies upon the right-hand end of the lever K, to which the weight J is attached. This weighted lever carries the shutter 11 and forces the pawl :0 into engagement with the ratchetwheel E by raising the back end thereof. The pawl atac prevents the computation-wheel from moving in more than one direction. The plate V serves as a spring-brake,bearing against the side of the ratchet-wheel, and serves to throw the point of the operating-pawl I" above the teeth of the ratchet-wheel E,to permit the backward movement of the same, and in the forward movement of this pawl the inner beveled edge of the same acts to throw it off from thisplate to the teeth of. the ratchet-wheel.

On the rear posts of the frame and on the fixed shaft 0 is mounted the wheel D, which freely turns thereon, and on the peripheral face of which are marked numbers on spaces conforming to that of the computation-wheel. These numbers ordinarily will answer to fractional parts of a dollar. To the side of this wheel is attached the pinion G,which engages the rack-bar F, which at its forward end is pivoted to the arm I. The rack-bar is held into engagement with the pinion by a bearingpoint, Q, on the inside of the post. The connection of the two wheels through the rackbar causes a conjunctive movement, and the numbered spaces on both correspond. The shield m covers a portion of the face of the wheel D, and the shutter n is operated to open and close the orifice or window in this shield.

Thus but one number marked upon this wheel IOO mence with the wheels displaying ajcipher, now press on the button 15, so as to project into the path of the arm H, and carry the arm I r forward till the key comes against the said arm.

and then press the same back until the said arm I is arrested by the arm H of the frame. This would show 15 on the computation-wheel D, and also on the indicator-wheel D. Now repeat the to-and-fro movement again and you have 15 again on the peripheral face of theindicator-wheel D',and 011 the computator-wheel D you have 30,the sum of the two movements represented by 15, and so on, the individual number and sum appearing at the openings through the shields. I contemplate the construetion of much more elaborate machines and a considerable number of buttons or keys representing a large number of single numbers or individual amounts. The essential mechanism is here presented, and the modifications would be by duplication. The backward movement of lever I raises the point of the pawl P on the spring a. and this depresses the inner end of the lever K,which causes the shutter a to close the vision orifice in the shield m, which remains closed until the lever is returned to its former position. There can be no registration until the lever makesits full backward sweep; and this movement is neces sary to let the point of the pawl fall from the face of spring 12 to engage again the notches of the ratchetwheel, by which the computation- I wheel D may be moved.

To set the register at zero, disengage the pawls and reverse the movement until the cipher is exposedto view.

Having fully described my invention,what I claim, and desire to secure by Letters Patent, 1s

1. The operating-arm I, provided with a series of push-buttons corresponding to definite numbers, and the arresting-arm H engaged thereby in its backward movement, in combination with the rack-bar F, pinion G, and computationwheel D,wheel D, and operating-lever 1?, to give definite movements to said computation-wheel, substantially as set forth.

2. The combination of the computationwheel D with ratchet-wheel E, the pawl P,

pawl 00, operating-lever I, provided with the g adjustable buttons, arresting-arm H, rack-bar F, pinion G, indicating-wheel D, shields L and m, shutter n,weighted lever K, and traversing view-slide N, )rovided with projection eutering groove of said computation-wheel, substantially as set forth.

In testimony that I claim the foregoing as my own I aliix my signature in presence of two witnesses.

PHILIP YOE.
