KEY- FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 426,016, dated April 22, 1890. Application filed July 10, 1889. Serial No. 317,056. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM W. I-Irronooon, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Key -Fasteners, of which the following is a specification.

The object of my invention is to provide a compact, light, cheap, easily-constructed, and effective device to prevent keys in locked doors from being turned from the outside of the door.

My invention consists of the combination of a reciprocating tapering bolt widening from its free end and adapted to lit the ring of a key, a loop for suspending such bolt from the arbor of a door-knob, and springs arranged to force the bolt toward such loop.

The accompanying drawings illustrate my invention.

Figure 1 represents my key-holder in position securing a key in a lock. Fig. 2 represents my key-holder extended ready to be ap plied to the key.

A is the spring-actuated bolt adapted to fit the interior of the ring of the key. It is preferably formed with divergent sides a a, so that the bolt will fit rings of different sizes. I prefer to form this bolt of a single wire bent to form the bolt-loop A and the attachment and guide arms l3 l3.

C is a loop of wire, adapted to behung upon the arbor G of the door-knob K and provided with the two guide-arms D D.

The guide-arms B B are provided at their ends with the small loops 1) b, forming eyes, through which the arms D D of the suspend ing-loop 0 play, and the arms D D are provided at their ends with like eyes (Z (Z, through which the arms B B play.

Two wire U-springs E E, having their ends provided with hooks e e e e, are attached, respectively, to the eyes I) and d between such eyes, so that the springs E engage with the eyes I) and (Z to press them apart, thereby forcing the bolt A and suspending-loop (l toward each other.

lVhen the bolt A is formed of wire, as shown, a sheet-metal brace H, with thumbpiece I, is preferably provided to clasp the wires at the base of the bolt. The thumbpiece I forms a convenient handle to take hold of to operate the bolt.

To adjust my improved key-holder when the door is locked, the parts are extended, as shown in Fig. 2, and the knob is passed through the suspending-loop. The end of the bolt A is then guided into the ring of the key and the bolt is released. The springs E force the bolt up into the ring until the divergent sides aa come into contact with the sides of the ring. The tension of the springs holds the key firmly against the top of the key-hole. Any attempt to turn the key will be resisted by the bolt.

By constructing the several parts of wire as shown I secure lightness and compactness, so that my invention can be carried with but little inconvenience.

Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A key-holder comprising the combination of a reciprocating tapering bolt widening from its free end and adapted to fit the ring of akey, a loop for suspending such bolt from the arbor of a door-knob, and a spring arranged to force the bolt toward such suspending-loop.

2. A key-ho1der comprising the combination set forth of the bolt A, provided with attachment-arms B B and eyes I) b, the suspending-loop-C, provided with the guide-arms D D and eyes (Z d, and the springs E E, engaging with the eyes Z) and (Z to press them apart, thereby forcing the bolt A and loop 0 toward each other.

WILLIAM W. HITOHCOOK.
