ROBERT F. GIBSON, OF CLEVELAND, OHIO, ASSIGNOR OF ONE-HALF HIS RIGHT TO FRANKLIN N. CLARK, OF SAME PLACE.
IMPROVEMENT IN KEV-FASTENERS.
Specification forming part of Letters Patent No.
162,22, dated April 20, 1875; application filed April 2, 1875.
To all whom it may concern:
Be it known that I, ROBERT F. GIBSON, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new Key Tag and Fastener, of which the following is a specification:
This invention relates to a key-tag which serves both as a tag, and also as a key-fastener when the key is in the lock, to prevent the key from being turned from the outsideor opposite side of the door. It consists of a metal tag attached to the ring of the key, and having a hole in the lower end, by which it may be secured to a spring-catch attached to the door beneath the escutcheon or key-hole. \Vhen the tag is thus fastened it effectually prevents the key from being turned from the opposite side of the door with nippers or otherw1se.
To enable others to fully understand my invention, I will proceed to describe the same in detail, with the aid of the accompanying drawings, in which Figure 1 represents the edge of a door with a lock and key having my improvement attached. Fig. 2 is a side View of the same,
both figures showing the key fastened.
A represents a door, B, the lock, and G the key in the lock. D is the before-mentioned tag, and E is the spring-catch for securing the lower end of the tag. The spring-catch consists of a base-plate, e, and a spring plate, f, secured to the door below the key-hole by a screw at the lower end. The spring-platef has a pin, g, on its inside face at the upper end, which reaches into a hole made in the base-plate a for that purpose, there being a corresponding hole in the lower end of the tag D.
The operation of this is as follows: The door having been locked, the key is turned around again as far as it will turn, and the lower end of the tag is secured in the springcatch, as seen in the drawings. The key is now fastened, and cannot be turned either way by nippers or other means from the opposite side.
Having described my invention, I clain1 The tagD and the spring-catch E, in combination with the key 0, for fastening the key in the lock, substantially in the manner and for the purpose set forth.
