SEEGIFICATION forming part of Letters Patent N o. 707,603, dated August 26, 1902. Application filed (lune 5, 1900. Serial No. 19,094. (No model.)

.To @Z5 'zu/tant it may concern.-

Beit known thatLGARLLAURICK, a subject `of the King of Prussia, German Emperor, and

a resident of Berlin, in the Kingdom of Prus sia and Empire of Germany, have invented certain new and useful Improvements in Devices for Locking the Operating-@ranks of Cash-Registers, of which the following is a specification.

The object of the invention is to provide means for preventing the turning of the operating-crank of a cash-register until the salesman or operatorhas deposited within the cashregister a ticket indicating his name, number, or the like.

The invention is illustrated in the accompanying drawings, in which- ,:Figure 1 is a vertical longitudinal section of a portion of a cash-register casing,sho win g the application of the invention. Fig. 2 isaplan view of the same. Fig. `3 is a sectional detail.

In the drawings, A indicates a portion of the casing of a cash-register which is deemed sufficient for illustrating the present invention. An operating crank or handle is indicated at 1G, which is connected to and turns upon an operating-shaft 14. An arm 20 is carried by this shaft and in the normal position of the parts depends into the position shown in Fig. 1, where it is provided with a pin 120, which is engaged by the hooked end of a locking-arm 1S, pivotally secured to any iixed point within the casing. As long as this hooked arm is in engagement with the pin the crank of the register is locked against movement. In. order to disengage the arm 18 from the pin, I provide a rocking lever 129, carrying at its rear end a pawl 130, having a hooked portion engaging the hooked end of the arm 1S. The forward end of lthe lever 129 is designed to be operated by the slide mechanism hereinafter described.

A slide 23 is suitably guided in the walls of the casing and has in its upper surface a recess to receive a suitable ticket (indicated at 2l) which may be inserted through an opening 22 in the projecting portion of the casing. This slide tends to move toward the rear by the tension of a spring in the manner-hereinafter described. Aretaining-lever 121 is pivoted to a lug or projection 121 on the under part of the slide, and the lever is provided on its front end with a hook or catch designed to engage with the edge of the casing to thus lock the slide against rearward movement. The catch isheldin engagement with the casing by a spring 133, and the projecting portion 133 serves as a handle for the depression of the front end of the lever. In order to hold the lever 121 against movement except when the ticket has been inserted, I provide a transverse rock-shaft 29, which has a plurality -of depending fingers 30 extending down into the path ot' the ticket and also other fingers or projections 31, designed to engage the rear end of the lever 121,as shown in Fig. 1. lVhen, however, the ticket 21 is inserted and shoved rearwardly, the impact of the ticket against the iin gers 30 causes the projections 31 to be moved out of contactwith the rear end of the lever 121, which may then be depressed to release the slide. A supplemental slide 125 is suitably guided in the casing and is under the tension of a spring 122, connected to a pin 132 and tending to draw said slide 125 toward the rear. A pin 134:, carried by the slide 125, engages the front side of a stop 124 when ,the slide 125 moves rearwardly, and thus tends to carry the slide 23 back with it. The slide 125 has a projection 128, which engages the forward end of the lever 129 when the slide nears the limit of its backward movement, and thus releases the pin 120 from the arm 18 in the manner hereinbefore described. In order that the slide 23 may be restored to initial position, the cash-drawer (not shown) may be caused to engage the pin 132 when it is drawn out, and thus carry the slide 125 with it. A pawl 126 is pivotally connected to the slide 125 and has one edge adapted to slide upon the lower edge 127 of the guide, thus holding its upper edge or nose in contact with the rear side of the stop 124C until the slide 23 has been drawn forward suiiiciently to allow the catch on the lever 121 to engage the edge ol the casing. Vhen this point is reached, the lower edge of the pawl 126 reaches the cut-away portion 127, which permits the pawl to rock backward, as indicated in dotted lines, to clear the projection 124 and the cash-drawer to continue its outward movement without affecting the slide 23. On the reverse movement of the cash- IOO drawer the pawl will rock in the opposite direction and the slide 125 moves backward under the tension ofthe spring until the lower edge of the pawl engages the edge 127 of the: guide and the pin 134 comes in contact with A glass 123 permits of the inspection of thev ticket when it has been carried rearwardly by the slide.

From the foregoing description the operation of the device will be clear, but may be briefiy stated as follows: The crank 16 of the cash-register is normally held against movement, as indicated in Fig. 1. Thefsalesman who desires to operate the cash-register inserts a ticket through the opening 22 and pushes it rearwardly until it swings the projections 31 out of engagement with the lever 121. The operator then depresses the end `1332*, to be drawn rearwardlyy under the action of the spring 122, slides 23 and 125 moving rearwardly together. As soon as the slide 125 nears the limit of its backward movement the projection 128 contacts with the forward end of the arm 129 and raises the pawl 130, and with it the arm 18, thus freeing the arm 2O and allowing the cash-register handle to be operated. The cash-register may now be operated in the usual manner. In order to prevent a double rotation of the handle without the slides having been moved forward by the opening of the cash-drawer, a pawl 131 is pivoted to the arm 20, and which as the arm 2O nears its initial movement engages the pawl y130 and rocks it to disengage it from the end of the arm 18, allowing the end of said arm to drop into engagement with the pin 120.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with the operatingcrank of a cash-register, of a locking device for holding the same against movement, a slide for releasing said locking device, a spring tending to retract said slid e, means for holding the slide normally advanced, and check-controlled means for releasing said holding means, substantially as described.
