SPECIFICATION forming part of Letters Patent No. 492,646, dated February 28, 1893.

To the interior of the front wall of the 9 5 5 8 represents the walls of a suitable casing drawer and at the base thereof, is attached a Within which the various parts of my invennon-conducting or insulating strip 25 best tion are confined, although such casing is not shown in Figs. 3 and 6, and to said strip is seindispensable. This casing has suitable opencured a series of conducting contact plates 26 ings at at the bottom thereof for the reception whose position on said strip is determined by :00

o of wires leading to and from the battery as the relativeposition'of the numbers or figures fully shown in Figs. 5 and 6. on the number plate on the exterior of the drawer. The number of these contact plates is oneless than the numberindicated by the n umbers on the number plate so that when said plates are secured in position opposite the places occupied by the numberson the number plate, a space will remain between two of the contact plates on theinsulating strip The bottoms of the contact plates rest against a conducting plate 27 formed with or attached to the bottom edge of the insulating strip 25. This conducting plate 27 has connected to it one end of the wire leading from the battery in the drawer; the other wire connects with the opposite end of the spring plate 20.

It will be seen from an inspection of either Figs. 1, 3 or 5, that if the handle 14 be slid until the same comes opposite one of the contact plates 26, and then pulled forward until the disk 2t attached to red 21 comes in contact with one of said contact plates, such action will complete the electric circuit and the bell will accordingly sound; but if the handle it be slid until the disk 2t comes opposite the space between two of the contact plates and then pulled forward, the disk 2st will come in contact with the insulating strip 25 and the circuit is broken. It will further be seen from an inspection of the above figures that the contact plates 26 limit the forward movement of the handle it so that there is no possibility of the bevel piece 19 engaging with the beveled strip 5 of the looking device sufficiently to depress the same and opening the drawer. \Vhen, however the handle 14 comes opposite the space between any two contact plates, the forward movement of said handle is not limited, the bevel piece 10 engages with the strip 5 depressing the latch and the drawer opens. It will thus be seen that the latch opens at a time when the circuit is broken, and at any other time, or when the position of the handle is such that it does not come opposite the space between two contact plates, the circuit will be closed at the slightest provocation in any attempt to pull upon the knob of the handle; and a person not knowing opposite which number on the number plate the space between the contact plates is located, and consequently ignorant of the exact spot or number to which the handle should be slid, would in the attempt to open the drawerclose the circuit and sound the alarm. \Vhen the drawer is closed and the handle is slid at random to any position indicated on the number plate, the said handle or rather the disk 2t thereof is kept out of contact with the contact plates by the resilient action of the slotted spring plate 20 which not only acts as aguide for the lateral movemeutof the handle, but also retracts the handle to its normal position after the hand of the operator has let go of the same. The disk 24 is made narrower than the space between the contact plates so as to avoid the danger of making contact if by carelessness the operator did not move the handle precisely opposite the center of such space.

The conducting plate 27 which conducts the current from the contact plates 26 back to the battery 13, may be secured to the insulating strip 25 in any suitable manner or it may be cast with the strip 25 and then insulating material be put upon said strip subsequently. The conducting plate 27 may be marked with suitable division lines 28 opposite which the contact plates 26 are secured on the insulating strip 25. In the drawings they are shown as secured by screws, but it is obvious that any other mechanical way would suffice and I do not accordingly limit myself to the precise construction herein shown.

The numbers on the number plate may either be cast with said plate or may be painted thereon or indicated in any other way. If cast, they may be raised at the same time and thus the operator can feel the combination or the exact number to which the handle should be moved even on a dark day and thus not be annoyed by looking or hunting for the combination in order to open his drawer.

It will be readily seen that the contact plates 26 can be shifted at will on the insulating strip 25 and can be moved so as to bring the space between two of them opposite any 5 desired number on the number plate. Accordingly, any combination can be effected by the arrangement herein shown. In actual use of the drawer the operator after closing the same may shift the handle to that position of the slot at which if the same be tampered with or pulled by an unauthorized person the same will come in contact with the contact plate and immediately sound an alarm.

Although the battery and bell are herein shown as located in the drawer, it is obvious that the same may be located outside thereof without departing from the spirit of my in vention.

Having fully described my invention, what I claim is- 1. A money drawer having a series of contacts interrupted by a space, a handle for said drawer, a contact on said handle co operating with said contacts and space, a lock for the drawer, and suitable means for operating said look when the handle is brought opposite the space between the contacts, substantially as set forth.

2. A money drawer comprising an electric circuit, a sliding handle located on the front wall of the drawer, a slotted spring plate guiding said handle and connected with one end of the circuit, contact plates connected with the other end of the circuit, and means for connecting said handle with the contact plates for completing said circuit, substair tially as described.

3. In a money drawer, a sliding handle, a slotted spring plate, a connecting rod moving in the slot of said plate, and connected to said handle, insulating material between said rod and handle, a disk attached to the forward end of said rod, and contact plates co-operating with said disk, substantially as described.

4. In a money drawer, a sliding handle, an insulating strip secured to the front wall thereof, contact plates removably secured on said strip with a suitable space between two of said plates to present an insulated surface, a conducting plate in contact with said contact plates, and connected with one end or wire of the circuit, and a contact on the handle 00- operating with said contact plates, substantially as described.

5. In a money drawer, a sliding handle provided with a suitable index, a number plate co-operating with said index, a beveled arm at the rear of said handle, a beveled strip 00- operating with said arm, guides for said strip, a rod attached to said strip and a beveled latch at the end of said rod, a lug on the drawer limiting the movement of said strip, a coiled spring below the latch, and a second lug limiting the movement of said spring, substantially as described.

6. A money drawer comprising a sliding handle, a slotted spring plate connected with one end of the circuit, an electric circuit, a connecting rod moving in the slot of the spring plate and connected to said handle, insulating material between said rod and handle, a disk attached to the forward end of said rod, an insulating strip attached to the -front wall of said drawer, contact plates re- WILLIAM J.
