UNITED STATES HERBERT T. BRADLEY,

CASH-R SPECIFICATION forming part of Letters OF DETROIT, MICHIGAN.

EGIVSTER.

Patent No. 434,374, dated August 12,1890.

Application filed January 11 1890. Serial No. 336,612. (No model.)

To all whom it may concern:

Be it known that I, HERBERT T. BRADLEY, a citizen of the United States, residing at Detroit, county of IVayne, State of Michigan, have invented a certain new and useful Improvement in Cash Registers and Indicators;

- and I declare the following to be a full, clear,

reference being had to the accompanying drawings, which form a part of this specification.

My invention is designed to produce a cash register and indicator which shall be positive in its operation and yet simple in construction; and it consists of a combination of devices and appliances hereinafter described and claimed.

In the drawings, Figure 1 is a perspective View of the exterior of my machine. Fig. 2 is a vertical section of the same. Fig. 3 is a horizontal section with the parts in elevation. Fig. 4 is an elevation of the key-table. Fig. 5 illustrates the mechanism for operating the table. Fig. 6 is a perspective View illustrating a portion of the mechanism; and Fig. 7 is a detail perspective View of the arms for operating the table or carriage by sliding the drawer.

. In carrying out my invention, A represents the case of my machine.

B is a series of operating-keys adapted to be struck by the operator in recording a sale. Each key represents one of the digits, and there is also a key for the 0. Each key has a shank b, which extends down into the case,

the lower end entering and playing in the bar B which extends across the machine. The keys are thus supported so that they can have a free vertical movement.

0 are levers extending from front to rear of the case and supported by the bar 0', which extends across. To the front end of each of the levers G is pivoted one of the keys, as at b, the engagement being such that as the key is struck the rear end of the lever will be thrown up. On this rear end is a transverse slot or opening 0.

D is what may be termed a movable table or carriage, and on this table or carriage the recording type-levers E are mounted.

These type-levers are preferably shaped, as shown in Fig. 2, in the form of a bell-crank, and are pivoted to the table or carriage at e. The lower or short arm 6' extends down and enters the slot 0. 0n the end of the upper or long arm 6 is the projectionc containinga recording-type corresponding with the figure on the corresponding actuating-key B. These type-levers E are all set at such an angle that when actuated the projection e of each typelever will pass through the orifice d of the table or carriage.

F is a roll of paper, and G is a roll on which the paper is wound after the recording has been done. Between the two is what may be termed a stationary platen H. The projection passing through the orifice, the type strikes the paper and records the figure.

d is an inking-roller mounted on the spring d and adapted to ink the type just before it strikes the paper. I

I will now describe the mechanism whereby a motion is imparted to the table or carriage. I is a universal bar extending across the machine underneath the levers O and back to the rear of the machine. This bar is pivoted at 1'. J is a wheel or drum pivoted to the table or carriage D and provided with the spring J. J is a rack-bar attached to the case. A portion of the periphery of the drum or wheel J is provided with the teeth j, adapted to mesh with those on the rack-bar, while the balance is provided with the ratchet-teet-hj. J 3 is an escapement-lever pivoted at j to the table. This escapement-lever is connected by the rod J 4 with the rear end a" of the bar I, and the construction is such that the raising of the rear end of the bar I operates the escapement-lever J so that the pawl 7' on the lower end engages in the ratchets and prevents the revolution of the wheel. Then when the bar I is lowered the wheel or drum J, through the spring 'J, will be revolved until the upper end 3' engages in the next ratchet-tooth. The pawls j j may be pivoted on the escapement-lever J 3 to render the ratchet; but the pivoting of the pawls is not indispensable. The wheel meshing with the rack-bar will thus move the tab e the space of one ratchet eachtime the front end of the bar I is depressed, "or, in other words,

them more capable of engaging and releasingeach time a key is struck. Thus if the operator wishes to record a sale of twenty-five dollars and thirty-seven cents he strikes first key No. 2. This operates, through the lever C and key E, to record on the paper ribbon the figure 2, and when the actuating-key is released the table, through the medium of the rack-bar J wheel J, and spring J, is moved along one space, ready for the figure 5 to be recorded, and so on until all four figures have been recorded.

I will now describe the mechanism for moving the paper: K is a bar extending from front to rear of the machine, the front end pivoted at 70 to the end of the universal bar I, while the bar is fulcrumed at 70, being movable horizontally on this fulcrum. A spring 70 serves to keep the bar in the position shown in Fig. 3 until moved by exterior means. K is an arm or red extending down from the carriage or table adjacent to the bar K, so that as the table moves to the right when the key is released it carries the bar K with it. L is a vertical rod supported at Z, the lower end being in such position that as the bar K is forced to the right by the table or carriage it will be under the end of the rod L after the key for the next to the lastfigure is struck and released, as illustrated in Fig. 6. Now when the last key is struck the depression of the front end of the bar K acts to force up the vertical rod L. M is a small pivoted lever or pawl having the pivoted segment at on its end. M is a ratchet-wheel keyed to-the shaft of the drum on which the paper is wound. Now when the last key is struck, as before explained, and the rod L raised, it presses against the lever M and drops the segment m down under the next tooth. Then the release of the key and lowering of the rod allows the spring M to bear on the lever M and move the wheel one space. This moves the paper up opposite an opening in the case, so that it can be seen from the exterior, and by placing the lens M in the case the figures will be enlarged, so that they can be plainly seen. The segment m is pivoted and arranged as shown to enable it to yield and move down past one of the teeth of the ratchet-wheel M, so as to be placed under such tooth 'for turning the ratchetwheel one tooth when the rod L descends.

I will now describe the mechanism for operating the cash-drawer and for returning the table or carriage to its normal position after a sale has been recorded. N represents the drawer, and N is a spring placed behind it for throwing it out when released. 0 is a small latch pivoted to the case, having on its under side a beveled projection 0, adapted to engage in a notch on the side of the drawer. The side of this latch also has a projection 0, under which the bar K is forced by the last movement of the table or carriage, as shown in Figs. 3 and 6. Thus the striking of the last key operates to raise the latch O and release the drawer, which is forced open by the spring. P is an arm extending from the side of the case above the drawer and supports on its outer end a vertical pivot. Keyed to the upper end of this pivot is the arm P, adapted to bear on the arm or rod K, which is attached to the table, and keyed to the lower end is the arm P extending horizontally to the edge of the drawer. P is a pin or projection on the drawer adapted to strike the arm P As the drawer is thrown out, this pin or pro jection strikes the arm P and revolves it until it has passed, when the spring 19 throws itaround until the arm P bears on the rod K. Now as the drawer is closed this pin or projection, bearing on the arm P causes the arm P to move the table back until the pin has cleared the arm P The table is thus thrown over ready to have another sale recorded, and the spring serves to return the rod K to its normal position.

I have heretofore explained the manner of recording a sale the amount of which contains four figures. In order to provide for recording a sale of less than four figures, the space-key B is provided. This key makes no record, but simply acts on the universal bar and moves the table. Thus if one dollar and eighty-eight cents are to be recorded the operator strikes the space-key first, then 1, 8, 8; if twenty-five cents, he strikes the space-key twice, then 2, 5; if seven cents, he strikes the space-key three times, then 7.
