,UNITED STATES PATENT -OEEICE GEORGE H. PEAOOOK, OF WEBSTER, ASSIGNOR TO GEORGE PLUME AND SUSAN A. NEWMAN, OF FAIRPORT, NEW YORK.

IMPROVEMENT IN COMBINATION TILL-LOCKS.

Specication forming part of Letters Patent No. 170,108, dated November 16, 1875; application. filed May 24, 1875.

To all whom it may concern Be it known that I, GEORGE H. PEAcocK, of Webster, in the county of Monroe and State of New York, have invented certain Improvements in Combination-Locks, of which the following is a specification:

My invention relates to the construction of a lock or guard, more especially for tills or money-drawers, so Vdevised as to be readily opened by the proper manipulation of the iinger-bars or tumblers, thus obviating the necessity of using a key.

Figure l is a front view of a portion of the Working parts, having the outer bank of En ger-bars, cross plate, and thumb piece removed.' Fig. 2 is a front view of Working parts. Fig. 3 isa sectional side view of working parts. Eig. 4is a back view of the lock; Fig. 5 is an edge view of one of the fingerbars. f

A is the back-plate. C is the bolt-carrier, which slides on the back-plate, guided by the studs F and R. Qfis the thumb-plate, having a projecting arm, S,', Fig. 3, entering an opening in the bolt-carrier B, B, B, B, and B, Fig` l, are linger-bars, one or more of which may be raised in opening thelock. S, Fig. 27 the cross-plate in front of 'the fingerbars B,"B, "B, B, and B. B', B', B', B', and B', Fig. 2, arealso finger-bars. In the upper side of the erossplate S, Fig. 2, is a diagonal slot, T, in which the end of the pin G of the bolt-carrier O may be moved. pressure is applied against the outer part of the thumb-plate Q, the projecting end of the arm S' forces downthe bolt-carrier C, while the pin G, moving in the diagonal slot T, moves the cross-plate S to the right. N is a spring, which moves the bolt-carrier upward, and, consequently, moves the cross-plate S to the left. A is a T-shaped guard, projecting Thus,` when.

from both sides of each finger-bar. The hory' the shoulder z may pass by the T`shaped I guard, thus permitting the cross-plate S to move to the right, and hence allowing the v bolt-carrier to be moved` back. Similar sh'oulders z are provided on the inside ot' the'faceplate to act in like manner on the T-shaped guards of the linger-bars B', B', B', B', and B'. X, Fig. 49 is fthe guard-plate, the supporting ends of which enter the bearings P P, Fig. 2, of the back-plate, thus allowing the guard-plate tobe either suspended by its own gravity, or turned up s0 as to inclose the iinge ars. I is a guard, located between the supporting ends, and projecting at right angle to the plane ot' the guard-plate. Thus the bolt-carrier C can be forced down only when the guard-plate is turned up, so as to allow the heel of thebolt-carrier to pass in front of the guard I, Fig. 1, ot' the guard-plate w.

I claim- 1..The combination of the bolt-carrier O, thumb-plate Q, cross-plate S, and nger-bars B B B B B and B' B' B' B' B', as herein described.

2.- The guard-plate X, in combination with the bolt-carrier D, as herein described..
