IMPROVEMENT IN KEY-FASTENERS.

Specification forming part of Letters Patent No. 213,590, dated March 25, 1879 application filed January 29, 1879.

To all whom it may concern:

Be it known that I, ALBERT E. PEoK, of the city of Providence and State of Rhode Island, have invented a new and useful Improvement in Key-Fasteners; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

Figure 1 is a perspective view, showing the application of my improved key-fasteners to an ordinary door-lock. Fig. 2 is a sectional view of my improved key-fastener, showing the construction of its parts.

The object of this invention is to so construct a key-fastener that a key of any size may be firmly held and prevented from turningin the look by any unlawful means; and also so that the key-lock will automatically secure itself to the key, so that it cannot be pushed off by any tool or wire so as to release the key.

The invention consists in the peculiar arrangement of the parts, as will be more fully set forth hereinafter, and pointed out in the claims.

In the drawings, A represents a door, and B G is the key-hole, and D the key. 6 is a cap or case, of such shape and dimensions that it will readily pass over the loop of the key, and prevent it from being turned around. The cap 0 is secured to or forms part of the hinged arm f, which is at its lower end secured to the door by the hinge-plate 9, either by a screw cast on the plate g, or by two screws extending through said plate. To securely and automatically fasten the cap 6 to the key,

' the hinged latch, held by a spring, is secured to the cap 6, and when the same is pushed over the loop of the key the cap 6 will be firmly held to the same by the latch, and cannot be pushed oft by extending an instrument through the key-hole.

With a key-fastener it is important that the key can be secured or released in the dark on the inside of the door, and that it be so easily operated that any one can secure the key or release the same at the inner side of a door, but also so that no kind of instrument can release the key-fastener or turn the key.

To facilitate the fastening of the key the lower end of the arm f is provided with a camflc, resting on the spring '5. The cap 6, being made to cover the whole of the loop and being of smooth rounded outline, is not liable to catch in clothing, and be thus injured. The whole is neatin appearance, simple, and strong in its construction,readily secured to anydoor, and the key can be securely fastened by simply raising the hinged arm 3, and it will be antomatically held and firmly secured by the spring-pressed latch h. It can be as readily released and operated in a dark room, while the key cannot be tampered with from without.

Having thus described my invention, Iclailn as new and desire to secure by Letters Pat- Gilt- 1. The combination, with the hinge-plate 1, spring i, and cam k, of the arm f, provided with the cap 6, arranged to hold a key from being turned, substantially as and for the purpose set forth.

2. The combination, with the hinged arln f and cap 6, of the spring-pressed latch h, arranged to secure the cap 0 automatically to the key, as and for the purpose set forth.

ALBERT E. PEOK.
