UNITED STATES EGBERT O. TOOD, OF NASHUA, NEV HAMPSHIRE.

IMPROVEMENT IN TILL-ALARMS.

Specification forming part of Letters Patent No. 145,824, dated December 23, 1873,' reissue No. 5,820, dated March 31, 1874; application led February 28, 1874.

To all whom it may concern: v

Be it known that I, EGBERT O. VOOD, of Nashua, in the county yof Hillsborough and State of New Hampshire, have invented a new and useful Improvement in TlLAlarms, of which the following is a specification:

Figure 1 is a top view of the part of my improved device attached to the till. Fig. 2 is an under-side view of the part of my improved device attached to the cover. Fig. '3 is a vertical section taken through the line zr, Fig. 1. Fig. 4 is a vertical section taken through the line y y, Fig. 3. Fig. 5 is a detail top view of the lever for sounding the alarm. Fig. 6 is a detail side view of the ratchet. Fig. 7 is a detail top viewof the bed. Fig. S is a detail side view of a tumbler and key.

Similar letters of reference indicate corresponding parts.

In my improved till the keys and tumblers are so connected in pairs, and arranged relatively to locking and alarm-operating devices, as to act on the same in a peculiar way; also, the lock-plate operates in connection with inclined lugs, passing alternately beneath and above them as the drawer is moved, all as hereinafter described.

Arepresents the till or drawer, and B is the cover to which my device has been attached. The cover B may be a counter, table, desk, or other stationary board, to which are attached the cleats upon which the till or drawer A slides. C are the side plates of the box, which are secured to the rear or inner end of the till A by screws passing through lugs formed upon the upper rear part of said plates. D is the front plate, the edges of which fit into shallow grooves cast in the forward part of the inner sides of said plates O. E is the slotted bottom plate or rack, through which the keys or levers pass, and the side edges of which enter grooves cast in the lower part of the inner sides of the plates (l. F is the bed, the lower edges of the sides of which rest upon anges cast upon the upper part of the plates C. The side plates C are secured to each other, clamping the front plate D, the slotted bottom plate E, and the bed F between them by a bolt and nut, G, which bolt passes through a transverse groove in the upper part of the ribs or partitions of said bed F. IThe bed F is slotted lonother, and with the side bars of said frame, as

shown in Fig. 7. Upon an upward projection upon the rear part of the side plates C are` formed lugs H, made with horizontal sides, vertical forward sides, and inclined upper or rear sides, as shown in Fig. 2. Upon the bolt G are strung the levers or keys l and the tumblers J a key and tumbler being placed in each slot of the bed F. The adjacent sides of the pivoted parts of the keys I and tumblers J are halved to each other, so as to form shoulders to enable the tuinblersv to be moved by the movement of the levers, whether' the said tumblers be turned forward or back. K is the lock-plate, upon the rear ends of the side edges of which are formed lugs le', of such a size as to pass through the space below the lugs H.

K The rear end of the plate K is held down by a spring, L, placed above it, and secured to the board B by the plate M, to the forward part of which the said lock-plate is pivoted. The downward movement of the plate K is limited by a11gesm1,cast upon the plate M. Upon the rear end of the plate M is cast a downwardly-projecting iiange, m2, which, when the till or drawer is closed, enters a notch in the rear end of the said till or drawer, and covers and protects the operating parts ofthe device. Upon the forward; side of the ange m2 is cast a projection, m3, against which, when the drawer A is pushed in, strikes the lever N, to which the hammer O of the bell P is attached, and sets said lever N. r1`he lever N has a notch cast in it to receive the pivoting-Hange cast upon the plate G, and a pin cast upon it to receive the spring Q, by the elasticity of which the hammer is thrown forward to strike the bell when the lever N is released from the ratchet It. The ratchet R is made in the shape shown in Fig. 6, and is pivoted to the plate (l in such a position that its lug r may project along the forward side of the lug H, so as to be struck by lug k of the lock-plate K. The ratchet R is held in position for its hook end to catch upon the lever N by acoiled spring, S, interposed between the lug r of said ratchet and the inclined lug H, as shown in Fig. 3. The tumbler J is made with a short arm upon the rear part, and a longer arniupon the forward angles with its plane, may project over thetop edge of the rear bar of the frame of the bed F, between the partitions or ribs of said bed, and thus serve as catches to receive the ends of the short arms of the tumblers J, and prevent them from being turned over accidentally by the .friction of the plate K in opening1 the drawer. The teeth of the comb T are held forward in position to receive the short arms of the tumblers J, and said plate is made to yield, to allow said short arms to pass in and out, by a coiled spring, U; interposed between its lower part and the rear side of the bed F, as shown in Fig. 3. The keys I are operated by rods V, attached to their lower ends, and which pass through guides W, attached to the bottom of the till or drawer A, and have iin ger-pieces X attached to their forward ends.

With this coi'istruction, when the tumblers are allv turned forward, so that their short arms project upward, the drawer may be moved out and in freely. Should one or more of t-he tumblers J be turned back, so that their long arms project upward, the drawer cannot be drawn out without iirst forcing the said long arm of the tumbler or tumblers downward by operating the keys of the tumbler or tumblers that were turned back. When the key of a tumbler that has been turned forward is operated, the short arm 0f said tumbler is raised so as to prevent the plate K from dropping down and passing out beneath the lug H. Y/Vhen an attempt is made to open 'the drawer with one or more of the tuinblers raised, the lug 7a of the plate K will strike against the lug r' of the ratchet R, and, releasing the lever N, will sound the alarm. As the till or drawer is closed, the lugs k of the plate K slide up the inclined rear sides of the lugs H, and drop down in front of said lugs H, the rear part of the said plate K resting upon the upwardly-proj ectin g arms of the tumblers J.

The alarm is set by turning` one or more of the tumblers J to the rearward, and the combination is changed by turning one or more of the tumblers forward or back, as may bc desired.

Having thus described my invention, what I claim isl.. The tumblers J and keys I, constructed substantially as herein shown and described, in combination with the bed F, bolt Gr, and. lock-plate K, as and for the purposes set forth.

2. The inclined lugs H, formed on the side plates C, in combination with a hinged lockplate, K, provided with lugs K', to operate substantially as and for the purpose specified.
