IMPROVEMENT IN TELL-ALARMS.

Specific-ation formirg part of Leiters Patent No. l15,777, dated D. emit-163, 1873; application filed November 1, 1873.

To all whom it may concern:

Be it known that I, J onN F. BALDwiN, of Nashua, in the county of Hillsborough and State of New Hampshire, have invented a new and useful Improvement in Alarm -Tills, of which the following is a specification:

Figure l-is a longitudinal section of a till to which my improved device has been applied, taken through the line x a, Fig'. 2. Fig. 2 is a top view of the inner part of the same withdrawn. Fig. 3 is an under-side view of a part of the cover of the same. Fig. 4 is acrosssection of the same, taken through the line y y, Fig. 2. Fig. 5 is a detail view of the ratchet.

Similar letters of reference indicate corresponding parts.

The invention will first be fully described, and then pointed out in the claim.

A represents the till or drawer7 which moves out and in upon cleats attached to the cover B, which may be a counter, table, desk, or other stationary board. The receptacle in which the bolts and levers are placed and work consists of the box C, the front and sides of which are cast in one piece, and the rear side of which is closed by the guide-plate D. The plate D and front side of the box C are made with shoulders or offsets in their middle parts, to form in the upper part a narrow space to receive the bolts, and in the lower part a wider space to receive the levers, which levers and bolts are kept in place laterally by points east upon the inner sides of said plates. The guideplate D has cross-flan ges formed across its rear side to rest against the end of the till or drawer, and hold the said guide-plateD erect while it is held in place by th'e box O. The box C is secured .in place by screws passing 4 through lugs cast upon the lower edge of its front and the top of its sides, as shown in Figs.

2 and Ll. E are the bolts, the bodies of which fit into the upper chamber of the box C D, and the top of which projects in front and rear t0 rest upon the upper edges of the box C and guide-plate D. The lower ends of the bolts E are inclined, as shown in Fig. l, and rest upon the upper ends of the one-armed levers F. The levers F 4are made in the shape shown in Fig. l. In the rear edge of the levers F is formed a notch to receive the edge of the cross-iian ge G, formed upon the guidefplate D, to support the said levers and serve as their fulerum. Upon the lower part of the single-'armed levers F is cast a point to receive one end of a coiled spring, H, the other end of which is received upon a point forlned upon the inner surface of the front of the box C. By this construction, when the lower parts of the oncarmed levers F are held back by the springs H, their upper ends are inclined to correspond with the inclined lower ends of the bolts E. Vhen the bolts E are so arranged that the inclination of their lower ends may correspond with the inclination of the tops of the levers F, the forward movement of the lower ends of said levers F will raise the said bolts 5 but when the bolts E are reversed, as shown in dotted lines in Fig. 1, the forward movement of the lower ends of the said levers F will lower the bolts E. I is a plate, which is secured to the cover B in such a position as to be directly over the parts of the alarm attached to the till or drawer A when said drawer or till is closed. To the forward part of the plate I is pivoted the forward edge of the plate J, the rear or free part of which is held down by a spring, K, placed between it and the cover B. rllhe rear edge of the plate I, when the drawer is closed, rests upon the tops of the bolts E and against the lugs or inclines L, cast upon the upwardly-projecting sides ofthe box A. Upon the side edges ofthe rear part of the plate J are formed lugs M, of a length equal to the length of the inclined lugs L. By

this construction, when all the bolts E are down, the lugs M, when the drawer or till is drawn outward, will pass out beneath the lugs L; but should the till or drawer be drawn upon without all the bolts being down, the lugs M will strike against and cannot pass the lugs L. "When t-he drawer is pushed shut, the lugs M -slide up the inclined sides of the lugs L, and

drop down in front of them. Nis abent ratchet or lever-catch, which is pivoted at its angle to the upper part of the side of the boX A, in such a position that the lug n', formed upon the upper end of said ratchet, may project along the forward side of one of the lugs L. rEhe lug n of the ratchet N is held out from the lug L, and the other or engaging end of said ratchet is held raised, so that its hook or catch end may catch upon the lever O, to the end of which is attached the bell-hammer P for striking` the gong Q. The other end of the lever O is pivoted by bein g; notched and inserted in a vhole in the other side of the box A. The lever O is thrown back to sound the alarm, when re! leased from the ratchet N, by one or more springs, R, interposed between it and the plate D. Upon the rear or inner end of the plate I is cast a ange, S, upon the forward side of which is formed a projection, T. By this construction, when the drawer or till is drawn upon without all the bolts E being down, the lng M strikes the lug n of the ratchet N, and, releasing the lever from said ratchet, sounds the alarm. The levers F are operated by rods U, working` in guides V, attached to the bottom of the till or drawer A, and having` fingerpieces XV formed upon or attached to their forward ends.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combina-tion, in a tillalarni clock, of the straight bolt E, extended bar, trip J 011 top of drawer, and one-ar1ned lever F, substantially as and for the purpose described.
