SPECIFICATION forming part of Letters Patent No. 478,392, dated July 5, 1892.

Application filed April 1I 1892. Serial No. 427,352. (No model.)

To af/ZZ whom it may concern,.-

Be it known that l, HUGO BRAV, manufacturer, of Berlin, in the Kingdom of Prussia and German Empire,haveinvented newand useful Improvements in Attachments for Drawers and Tills, of which the following is a specification, reference being had therein to the accompanying drawings. i

This invention has for its object to prevent unauthorized opening of counter tills or drawers, as it is a well-known disadvantage of tilldrawers as at present constructed that access can be readily had to the till not only by the shop-keeper from the insideof the shop-counter, but also from the'side of the customer by bending over with the upper part of the body. In this new arrangement the drawer cannot be opened by pulling with the hand the front or a knob or handle, but is opened by pressing with the foot on a foot-lever, the movement of which is transmitted by a combination of levers upward to the drawer. By this means unauthorized opening of the drawer from the side of the customer is entirely prevented, because the said foot-lever cannot be operated either from the front through the solid longitudinal wall of the counter, norcan it be operated by bending over with the upper part of the body over the counter. authorized insertion of the hand of any person into the open till the hand of such person will be caught or jammed therein."

Reference is to be had to the accompanying' drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the iigures.

Figure l is a longitudinal elevation, the counter being in section. Fig. 2 is aplan View showing the drawer broken away and the counter in section. Fig. 3 is a front elevation, the drawer and counter being in section.

The counter is indicated by the letter L, i; being its front orouter walLt' a side wall, and o the top. z is an intermediate vertical partition, and a a horizontal partition, on which slides the drawer S, which may in addition be guided in a horizontal direction by means of fillets or grooves.

The mechanism for moving the drawer is arranged at one side of the same on the fixed partition a, and consists, essentially, of a peculiar combination of levers, which is mainintov the open position.

On un-v tained in the normal position by 'a coiled spring and is connected to the drawer at e vand is operated in such a manner by depressing the foot-lever that the drawer is brought (Shown dotted in Fig. l.)

The two two-armed levers a a and b b are arranged behind each other and are pivoted or fulcrumed intermediate their ends to the partition z at c and c', respectively. All the arms a a and b b are suitably curved or bent and engage at their ends with pull or push rods, which transmit the movement. The front arm at of the lever a a is jointed by means of the rod d to the front arm b of the second le- Ver b b', and the rear arm a is jointed by means of the rod CZ to the pin e, which is fixed to the drawer. The rear arm b of the lever b b extends upward and is attached at its end s to a rod g, which extends in a downward and inclined direction and slides over a pulley or roller fr, which is pivoted to the partition z. The rod gis attached at its end g to a pull-rod h, which is connected at t" to the foot-lever f. This combination of levers is maintained under strain by a tension-spring k, which is fixed at one end to the longitudinal wall o of the shop-counter and is attached at its other end to the end s of the lever.

Fig. l shows the drawer S, with the pushing device in the two end positions. The position vwhen closed is shown in full lines. The openV position is shown dotted.

It will be readily seen that the opening can be effected in a very simple manner by depressing the foot-lever, and the open position is maintained so long as pressure is exerted by the foot. According to the extent of oscillation of the foot-lever the drawer can be opened to a greater or less extent. In this operation the rod 7L draws the rod g, which slides on the pulley or roller r, downward, placing the spring lo under strain thereby. The lever b b oscillates about c', and the rod d pulls back the lever ct a', so thatits arm a. oscillates in a forward direction and transmits this movement through rod d to the drawer. On releasing the foot-lever f all the parts are returned into their closing position by the pull of the spring 7c. The lever-arm a may also be provided with a pin a for the rod d for the purpose of more securely actuating the lever IOO a a. The axis of the rod (Z must ot course lie in the closing position labove the lever fulcrum or pivot c, or may even coincide with the same, so that an intentional direct pulling or pulling out of the drawer in a forward direction merely serves to force it more rinly into its recess.

IVhat I claim, and desire to secure by Iletters Patent of the United States, is

medium of the irst-named lever, substantially as described.

The combination, with a drawer, of an 0S- cillating lever in the shape of a compound curve, disposed vertically, a rod connecting the rear downwardly-curved end of said lever ,with the drawer, a second oscillating lever fulcrnmed intermediate its ends, and a rod connecting one end of said lever with the upwardly-cnrved front end of the first-named lever, the opposite end of said second lever having means for throwing it and provided with a retractil@ spring, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
