, UNITED STATES PATENT OEEIoE.
AMOS S. B L AKE, 0F WATERBURY, CONNECTICUT.
lMPROVEM ENTlN LOCKS FOR PlANOS,&c.
Specification forming'part of Letters Patent No. 186,450, dated January 23, 1877; application filed i September 28, 1876.
' To all whom it may concern:
Be it known that I, AMOS S. BLAKE, of Waterbury, in the county of New Haven and State 0t Connecticut, have invented a new and useful Improvement in Locks, which improvement is fully set forth in the following specification and accompanying drawing, in
which- Figure l is a side viewof the lock complete. Fig. 2 is an interior view of the look, the springcover-plate being removed. Fig.6 is a sectional view on the line 00 m, Fig. 1. Fig. 4.- is a sectional view on the line y 3 Fig. 1.
The object of my invention is to furnish a, lock-case, the cap or cover-plate of which acts shown in Figs. 1 and 3.
The outer end of the bolt is hook-shaped,
for engaging with the catch-plate E, as shown in dotted lines, Fig. 2. The face-plate C is rigidly secured to the main plate A, and has a mortise through which the bolt D passes. The elastic or spring cover-plate B is turned up on one side, and its ends turned up and in, so as to hook or lap over the main plate A, as
The center of the spring cover-plate rests or rather presses upon the bolt, and holds the latter in the locked or unlocked position by friction.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
The combination, with the main plate of the lock-case and the bolt, of the spring coverplate B, provided with hooked ends and bearing upon the bolt to hold it in position, substantially as shown and described.
AMOS S. BLAKE.

EDWARD F. COLE, CHAS. W. GILLETTE.
