Nature and UbjectsV of the Invention.

Our invention relatesvto the class oflocks usually appledto money-drawers under the counter of store, that is arranged to give an alarm when the drawer :is

tampered-with by other persons than those connected 'with the store or conversant with the lock; and

It consists in such a construction and arrangement ofthe several parts of which the lock is composed that a variety of changes may be readily and convenient-ly made in the tumblers that operate the catch, said change rendering'the lock susceptible of combinations that may be varied from time to time,

' as may be desired.

Description 'of the Accompanying Drawing.

Figure 1 is a vertical longitudinal section of a drawer having a lock embodying our invention.

Figure2 is a topjview of the lock, showing the catch raised up, to expose the interior of the lock, the hinged or pivoted catchxB, being also shown detached. I

General Description.

The lock is composed of the cast-iron case or trainework A, hinged catch B, series of tumblers O, horizontal guide-plates, D, levers E, and pull-wire F, and is' attached to the drawer G, as shown. y

An alarm-bell, H, with apparatus arranged, milch in the usual manner, for operating the hammer, is atached to the counter or table-tcp I in such a manner -that the catch B'will engage with the lever J and trip the hammer K, to strike the bell.' The levers E, 'corresponding in, number with the number of tumblers O, 'are made with three arms, as shown, and arej pivoted on a longitudinal wire, E, at the bottom of the case. The front and'rear arms of these levers E serve as arest for and the means by which to operate the tnmhlers O. The tumbleis O are made in the form shown, and'work loosely in holes in the guideplates D, and any-desired number of them may be used, with, ot' course, aV corresponding number of levers and pnllwires. The rear arms ofl levers -E have a downward projecting point that engages with acorresponding point projecting upward from the lower cross-bar of' the frame, which serves as a stop to too great a movement of the levers, and they also serve to hold the spiral springs L in place.`

The springs L hold the levers- E, tumblers 0, and catch B in the position shown in lign-1, so that the catch I will engage withlevers J and return them to that position, when they have beendrawn down, by pulling the wires F. Any number of the tumblers Oless than the whole may be turned around, asindicated by the dotted lines in fig. 1, "and, when so turned, drop down too liu' to affect the hinged catch B. As only those tumhlers that rest on' the rear arm of level' E operate thefcatch B, it will be readily understood that various combinations may be made to operate the 'catch by turning the tumblers around, and these may be varied at pleasure, and'known only to those` using the drawer.

When theileversare operated to let the tnmblers down, the catch B drops down by its own gravity be- .low the lever J, when the drawer may be pulled out.

' 'lhe drawer is thrust forward, or rather held in such a position that the catch B rests against the lever J by means ot' the spring N, which prevents the catch from dropping down until the drawer is pushed back alittle, to release the catch.

As a substitute for'the springs L the forward arm of levers E may be weighted, to bring them into the position shown.

Claims.

We claim as' our invention-.

1. The combination ot' the lthree a'rmed levers E, the reversible tumblers C, and catch B, when arranged substantially as set forth.

2. '.lhe combination of the springN and bell-lever J with -the hinged catch B, all arranged substantially as and t'or the purpose set forth. OYRUS TUCKER.
