PLATE AND SOCKET FOR TRUNK-LOCKS.

$PECIPICATION forming part of Letters Patent No. 331,426, dated December 1, 1885. Application filedMarch 12, 1885. Serial No. 158,612. (No model.)

.To aZZ whom it may concern.-

Be it known that I, FRANK W. MIX, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Plates and Sockets for Trunk-Locks, of which the following is a specification.

My invention relates to that class of trunklocks in which the lock proper is inclosed within a circular case upon the back of the hasp, which case engages with a round socket on the keeper-plate.

The object of my invention is to produce a lock-plate and socket that can be made with less labor and expense than the lock-plates and sockets heretofore in use with this class of looks. I accomplish this object by the simple construction shown in the accompanying drawings, in which Figure 1 is a rear elevation of my improved keeper-plate and socket. Fig. 2 is a front elevation thereof, and Fig. 3 is a horizontal section of the same on line 00 x of Fig. 1.

A designates the keeper-plate, and B represents the socket with its two lugs a a. The keeper-plate A differs from the keeperplates heretofore used in this class of locks, in having two oblong holes for engaging with the lugs a c of the socket. WVith this single exception, the keeper-plate is the same as those ordinarily used. The socket B is struck up from sheet metal or cast, and is mainly circular in form. The socket is swelled out at two places on its side wall, as at c a, and on the edge of these swelled-out portions are two projecting lugs, a a, which engage with the oblong holes in the keeper-plate. The object of the swells on the side of the socket is to bring the lugs a a far enough from the edge of the usual socket-opening, O, in the keeperplate to leave metal enough between the lugs and said opening to properly hold the lugs in place. At the same time said swells do not interfere with the proper fitting of the circular lock-case in the socket, as the form of said socket as thus struck up is circular for the main portion of its side wall, so that the socket properly holds the case. The inner wall of the socket, at its circular portion, is flush with the edge of the usual socket-orifice, C. The lugs a a are not only formed on the edge of the side walls of the swells e 0, but they are in the same plane as said walls.

I claim as my invention- In a trunk-lock of the class hereinbefore specified, the herein-described keeper-plate and socket, consisting of a socket having the swelled-out portions 0 c with the lugs a a on their edge, and the plate A having the lugreceiving recesses by the side of the usual socketorifice, all secured together, substantially as described, and for the purpose specified.
