Description

UNITED sTATEs PATENT oEEroE.
ROBERT WILSON, OF BURDETT, NEW YORK.
' LOCK FOR DOORS, CHESTS, &c.
Specification of Letters Patent No. 734, dated May 10, 1838.
To all whom it may concern 4 Be it known that I, ROBERT WILSON, of Burdett, in the county of rlompkins and State of New York, have invented a new and useful Improvement in the Construction of Locks for Doors, Chests, and other Articles, which is described as follows, reference being had to the annexed drawings of the same, making part of this specification.
The lock-plate A, Figure l, guards B, B, bolt C, staple D, and key pin E, are made similar to others in use.
The main spring F, is attached to the end of Athe bolt by a link and is then coiled at its other end around a stud inserted into the lock-plate in the manner of a main spring of a watch.
The improvement consists in placing a safety spring G behind the projection or shoulder H of the bolt when it is looked, which holds it in a locked position until said spring is pushed by the key below the shoulder H. This spring is riveted to the lock-plate at the other end of it. It has a lip L projecting toward the key pin upon which the key acts. small stud S inserted into the lock-plate to prevent its being pushed too far in.
Fig. 2 represents the safety spring G inverted. Over the lip of the safety spring I arrange a light guard spring I fastened at one end by rivets to the lock plate and having a pin J projecting from its under side toward the lock plate and against which it bears when the spring is at rest.
Fig. 3 represents the guard spring I inverted. In order to lock the bolt the key Under this spring is a the guard spring as far as the lip L of the safety spring. gently toward the person using it, which raises the guard spring. It is then turned till it passes between it and the lip of the safety spring. The key is then pushed in again, which depresses the safety spring and disengages it from the bolt. The main spring instantly throws the bolt back again in extending itself and thus the lock is opened.
The safety and guard springs may be arranged on either side of the bolt-the principle will be the same-or the spring point or lip may be placed on any line along the bolt, being protected by a guard spring either straight or circular, acting in either case on the same principle. y Y
Fig. 4 represents the key.
The invention claimed and desired to be secured by Letters Patent consists in The key is then drawn The combination and arrangement of the safety spring, spring-guard, and studs o1. points in the manner before described.
