Application filed November 20, 1888. Serial No. 291,412. (No model.)

Fig. 3 is a section of the said keys; but such registering devices form 75 stop-case like that shown in Fig. 2, omitting no part of the presentinvention and are therethe springs and showing the stops, and also fore not shown in the drawings and need no one of the keys partly depressed and in secdescription. It is sufficient for the present tion in the same plane as the section of the purpose to say that any well-known registerstop-case and showing a stop-separator or the ing devices adapted to be operated bythede- 80 part of a key which passes between the stops pression of the keys may be used in connecin plan; Fig. ,4, a front elevation of two adtion with the parts shown-as, for instance, jacent stops and of the stop-separator raised the registering devices shown in said patent and a vertical section in the axis of said stops to 'Webster.

of a part of the stop-case, the stops in the In carrying out our invention we prefer to 85 above-mentioned figures being represented provide each key K with a stop-separator I, as round-ended cylinders; Fig. 5, a vertical the same being substantially an arc-shaped section of a part of the stop-case through the piece having its center of eurvatu re in the axis centers of the stops and a front elevation of of the fulcrum-rod 713', on which the key turns,

The stop-separator is connected to the stops and of a stop-separator in the position key K by a web or upward extension i,

shown in Fig. 5; Fig. 7, aside elevation of one which reaches from the rear part of the up- 5 of the stops and of part of a stop-separator in per edge of said separator to said key, the sepits normal position (not raised) anda vertical arator, web, and key being preferably castiu section of the stop-case on the line x a; in one piece. The stop-easeJ consists, substan- Figs. 5 and 6, the stops in Fig. 5 to 7being reptially, of a tube provided with feet j, by means resented as balls or spheres; Fig. 8, a horiof which it is secured to the table horizontal I00 portion a of the case A by means of screws passing through screw-holes j in said feet. The stop-case J is arranged at right angles to the keys and parallel with the fulcrum-rod k. The stop-case J is provided with as many vertical slots as there are keys, arranged at equal intervals with said keys, these slots being on the back of the case and extending through the horizontal opening or bore of said case. The case is so arranged that the slots 9' allow the stop-separators to pass upward through them when the keys are depressed, so that were it not for the stops L described below all the keys might be depressed simultaneously, each stop-separator passing up through one of the slots j The stops L (shown in Figs. 2 and 4) consist of short cylinders having a sufficient diameter to fit the horizontal bore of the case 7' with a sliding fit and each having pointed or rounded ends Z, the aggregate length of all the cylinders being shorter than the inside length of said stop-casethat is, the length between the outer sides of the slots nearest the ends of the case by just the lateral thickness of a single stop-separator, so that the depression of any key will by pushing the stops aside close all the intervals between the stops, except the one occupied by the stop-separator first raised, and thereby prevent any other stop-separator from being raised, or, in other words, prevent the depression of any other key.

Balls L may be used in place of the stopoylinders L in precisely the same way as said stop-cylinders if the central opening or bore of the stop-case be made of sufficient diameter, as shown in Fig. 5, the balls rolling instead of sliding. Obviously disks Z as shown in Fig. 6, may be used to eltectthe same purpose as the cylinders and balls above referred to, the disks being arranged to roll in a suitable case and in the same plane with each other. In any form of the stops it is necessary that the combined length of the stops taken on a horizontal line through the centers of the stops should be less than the inside length of the case by an amount equal to the lateral thickness of the stop-separator, It is also apparent that the stops may be arranged above the rear arms of the keys or under the front arms of the keys and operate upon and be operated upon by said arms directly, said arms in that case being properly shaped to separate the stops.

The stops above described may be used with any series of keys, where, for any reason, it is desired to prevent the simultaneous operation by accident or intention of two keys of the same group, but will be found to be especially useful in machines where the simultaneous depression of two keys will operate the machine to an extent not greater than is due to the depression of one of said keys. The number of stops required is equal to the number of spaces between the keys of the group, the parts marked Z 1n Fig. 2, although resembling in form the stops L, not serving as stops, but merely as followers impelled by springs Z to hold the stops proper in contact with each other when no key is depressed and to bring the points of contact of the adjacent stops in the center of the slots j The parts Z in Fig. 3 likewise do not serve as stops, but merely fill the ends of the opening in the case and prevent the stops from reaching entirely across the slots 3 1t being more convenient in forming the stopcase of cast metal to drill it entirely through from end to end to receive the stops.

WVe claim as our invention 1. In a register, the combination, with two adjacent movable parts, as keys, of an arrester consisting of a rolling piece or body of a diameter greater than the space in the parts between the keys and a channel or holder for receiving and guiding such rolling arresterbody, substantially as described.

2. The combination of a series of keys, a tube or stop-case arranged at right angles with said keys and provided with a number of slots equal to the number of said keys, and a series of stops capable of rolling in said stop-case and arranged side by side within the same, the length of the combined diameters of said stops being less than the interior length of said case by the transverse thickness of said key when the same in being depressed strikes said stops, substantially as described.

3. The combination of a series of keys, each provided with a stop separator having a uniform thickness laterally, a tube or stop-case arranged at right angles with said keys and provided with a number of slots equal to the number of said keys, each of said slots being adapted to admit one of said keys, and a series of stops capable of rolling in said stopcase and arranged side by side within the same, the length of the combined diameters of said stops being less than the interior length of said case by an amount as great as the transverse thickness of a stop-separator, substantially as described.

4. In a cash registerand indicator, the combination of the operating-keys and the stops made in the form of balls and arranged to operate substantially as described.

5. In a cash register and indicator, the combination of the operating-keys provided with extensions and the stops made in the form of balls, substantially as described.

In witness whereof we have signed this specification, in the presence of two attesting witnesses, this 12th day of November, A. D. 1888.
