CASH REGISTER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 507,351, dated October 2 l, 1893.

Application filed February 24, 1892- Serial No. 422,673. (No model.)

T0 at whom it may concern:

Be it known that I, THOMAS CARNEY, 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 and Indicators, of which the following is a description, reference being had to the accompanying drawings, forming part of this specification.

Heretofore, in machines of this character which have employed a series of indicators or tablets representing the respective amounts to be indicated and registered, and a series of key-levers representing corresponding amounts, the indicators have usually been thrown into view, to make the indications, by the depression of the front ends of the keylevers and have been caught and held in view by some suitable supporting device when the key levers were released and reset to normal position. Uponthe operation of another lever the exposed indicator would be released and withdrawn from view, while the indicator corresponding to the newly operated lever would be lifted into view and held up by the supporting device.

In my improved machine the indicators are not lifted into view upon the depression of the front ends of the key-levers, as heretofore, but upon the re-setting of the keys and consequent lifting of their front ends and lo wering of their rear ends, the result being that when the front end of any key-lever is depressed its corresponding indicator remains out of sight until the lever is released, and then, as the lever returns to normal position, the indicator is lifted into view.

In the accompanying drawings Figure 1 represents a side elevation of the frame and indicating mechanism of a cash register, illustrating one method in which my new mode of operation may be carried out, a portion of the near side of the framework being broken away to expose the parts beyond it. Fig. 2 is a front elevation ofthe right and left hand sides of the machine, (the middle portion being broken away,) showing only that part of the machine which is in rear of the line 22 of Fig. 1. Fig. 3 is a detail view showing a modified form of connecting device between the key levers and lifting levers.

The same letters of reference are used to indicate identical parts in all the figures.

The indicators A are supported upon vertical rods 13 carried in' guides C D, the rods preferably being provided with collars E resting upon the lower guide D. To aid in resetting the indicators the rods B may be surrounded by spiral springs F confined between the collars E and upper guide 0. These springs will be compressed when the rods 13 are lifted and will assist the gravity of the rods and indicators in re-setting the latter when released.

Upon the forward sides of the rods B are formed or secured beveled projections or shoulders G which co-operate with a supporting bar to temporarily sustain the rods B in elevated position, with their indicators exposed, as will be hereinafter described.

The key-levers H are strung upon a horizontal shaft I near the front of the machine as usual, and have spiral springs II connected to them in rear of their pivotal support, to aid in re-setting them. The respective key levers are arranged approximately in line with the respective indicator rods B which correspond to them, and interposed between the rear end of each lever and its corresponding rod is a lever J, upon whose rear end the rod rests. These levers J are strung upon a horizontal shaft K. The front end of each lever is provided with a notch or mouth L and a beveled face M, which co-operate with a spring-plug N carried in a bore in the rear end of the corresponding key-lever. The plugs N are normally pressed outward by springs N confined in the bores behind them and may be forced inward against the pressure of the springs. When the front end of any key-lever is depressed and its rear end thereby lifted the rear end of the plug N strikes the beveled face M of the lever J and the plug is forced into its housing as its rear end rides up over said face. When the end of the plug passes above the face M it will spring rearward again into the notch L of the lever J.

It will be seen that the lever J and the indicator rod resting upon it will not havebeen moved by this operation, but when the keylever is released and its rear end begins to descend the end of the plug N will engage the lower wall of the notch L in the forward end of the lever J, and carry the forward end of the lever down with it and thereby lift the indicator rod resting upon therear end of the lever. \Vhen the rear end of the plug Nand forward end of the lever J in their downward movement reach the point where the arcs of the respective circles described by them intersect each other the plug will become disengaged from and release the lever and the latter will be re-set by the spring 0, one of which is connected at one end to each of the levers J in front of the shaft K and at its other end to a rod P extending across the entire machine.

Supported at its ends by pendent arms Q fast upon a rock-shaft R is the indicator-sup porting bar S which co-operates with the shoulders G upon the forward sides of the indicator-rods B. Projecting forwardly from the rock-shaft B, one near each end, are two arms T, T, resting on the rod P, and whose front ends are connected by a rod U extending across the entire machine above the rear ends of the key-levers H. It results from this construction thatwhenever the rodUis lifted the shaft R will be rocked and the supporting bar S thrown forward from under the shoulder G of any indicator-rod that may be resting upon it, thereby releasing such rod and permitting its indicator to drop out of sight.

When the front end of any key-lever is depressed to its limit of stroke its rear end will strike the rod U and throw forward the bar S to release any indicators which may be supported upon it. When the key-lever is released and its rear end begins to descend the rod U will drop back again and the bar S resume its normal position, and when the shoulder G of the rod which is beinglifted by the rear end of the lever J corresponding to the operated key-lever reaches the bar S it will push it slightly forward, pass it, and catch upon it when the lever J is released and re-set.

From the foregoing description it will be seen that when the front end of any key lever is depressed to its full extent its rear end will lift the rod U and move the supporting bar S to release any indicator rod or rods which may be upheld by it; and that when the keylever is released and re-set the indicator rod corresponding to it will be lifted by the lever J and caught upon and held up by the supporting bar S.

It will of course be understood that the mechanism of the machine is to be inclosed in a suitable casing having a window at which the indicators are exposed to view when lifted by the operation of their appropriate key-levers, as is usual in this class of machines.

My invention, in its broader scope, is not limited to the particular method and means I have shown and described for lifting the rods and indicators upon the return strokes of the keys, but contemplates broadly such new mode of operation, when accomplished by any means coming within the terms of my respective claims. Again, where levers such as the levers J are employed between the key levers and indicator rods, any suitable form of connecting devices between their front ends and the rear ends of the key levers may be employed in plaeeof the spring-plugs which I have shown. For instance, in Fig. 3 I have illustrated a gravity trip V which may be substituted for the spring-plug. These trips are pivoted upon the sides of the keys, in line with the levers J, and their rear ends or noses project to the rear of the ends of the keys into position to co-operate with the front ends of the levers J. \Vhen the front end of a keylever is depressed and its rear end lifted the nose of its trip V will ride up over the face M of the corresponding lever J,being depressed as it passes,and when it gets above said face the gravity of the forward end of the trip will re-set it and throw the nose of the trip up ward and rearward overthe end of the lever. When the key-lever is released and its rear end descends the rear end of its trip will engage the end of the lever J, and as the trip cannotyield in this direction it will carrythe front end of the lever J down with it and lift its rear end and the indicator-rod resting thereon. W'hen therear end of the trip and the forward end of the lever J reach the point at which the arcs of the circles described by them intersect each other they will become disconnected and the spring 0 will reset the lever, as before explained. Furthermore, the particular method I have described for moving the supporting bar S upon the positive strokes of the key levers, to release the elevated indicators, is not essential to my inveir tion in its broader scope, and other methods may be substituted for it.

Having thus fully described my invention, 1 claim- 1.
