KEY-FAS TEN ER.
SPECIFICATION forming part of Letters Patent No. 567,344, dated September 8, 1896.
' Application filed March 26, 1896. Serial No. 584,949. (No model.)
To all whom, it may concern.-
Be it known that we,FRED HOLLINGSWORTH and FRANK M. MCNEELY, citizens of the United States, residing at Norfolk, in the county of Madison and State of Nebraska, have invented a new and useful Burglar- Proof Key-Fastener, of which the following is a specification.
This invention relates to improvements in key-fasteners, and it has for its object to provide a device of this character whereby unauthorized persons shall be prevented operating a lock, thus rendering the latter burglarproof, and also to provide a fastener which may be readily attached to any key.
To these ends the invention consists, substantially, in the construction, combination, and arrangement of parts, as will be hereinafter fully illustrated,described, and claimed.
In the accompanying drawings, Figure 1 is a perspective view of a key disposed in a lock and having the herein-described fastener applied thereto. Fig. 2is a side elevation of the fastener removed.
Similar numerals of reference indicate corresponding parts throughout both the figures.
Referring to the drawings, 1 designates a clamping-ring formed of any suitable mate' rial and of substantially a C shape. This ring is provided at one side with an entranceopening 2, through which the shank of a key may be passed in order to apply the fastener to the same. The ring 1 at one of its sides is also provided with a threaded opening through which passes a set-screw 3. Opposite to the set-screw 3, and formed on the inner side of the ring 1, is a series of serrations 4, which, together with the set-screw 3, readily hold the shank of the key within the ring 1. The latter, also opposite to the set-screw 3, is provided at its outside with spaced parallel lugs 5, between which is pivoted a securing-blade 6, adapted to enter the keyopening in a lock and prevent the fastener turning. By pivoting the securing-blade 6 between the lugs 5 said blade is capable of being swung at various angles to the clamping-ring 1, thereby enabling the fastener to be conveniently and easily carried within a pocket, and also permitting the blade 6 to readily enter and'be adjusted to the keyopening of any lock, whether such opening be large or small, an advantage which would not be derived were the securing-blade formed stationary with the clamping-ring.
From the foregoing the operation and ad vantages of the fastener will be readily understood by those skilled in the art. When it is desired to secure a key within a look against removal by unauthorized persons, such key is turned in order to place the lockoperating portion of the same out of alinement with the key-opening. The fastener is then applied to the shank of the key, the latter resting upon the serrations 4 and being pressed against the same by means of the setscrew 3. the key-opening and the set-screw tightened, which retains the fastener rigidly upon the shank of the key, and the blade is thereby held within the keyopening of the lock. Thus it will be seen that any attempt from the outside of the door to remove the key from the lock is effectually overcome; and it is also apparent that by reason of the blade 6 the key is prevented being turned or pushed from the lock.
Having thus described our invention, What we claim as new is'- y 1. A key-fastener comprising a clampingring, a set-screw passing through the clamping-ring and adapted to retain the shank of a key therein, and a securing-blade pivoted to said clampin g-rin g and adapted to be swung at various angles thereto so as to readily enter and be adjusted to the key-opening of a lock, substantially as set forth.
2. A key-fastener, comprising a clampingring of substantially a C shape and provided at one of its sides with an entrance-opening, a set-screw passing through said ring and adapted to retain the shank of a key therein, and a securing-blade pivoted to said clamping-rin g and adapted to be swung atvarious angles thereto so as to readily enter and be adjusted to the key-opening of a lock, sub-- stantially as set forth.
3. A key-fastener, comprising a C-shaped clamping-ring provided with an entrance-- opening and having a series of serrations on The blade 6 is then inserted within ing-ring so as to readily enter and be adjusted to the key-opening of a 100k, substantially as set forth.
In testimony that We claim the foregoing as 10 our own We have hereto affixed our signatures in the presence of two Witnesses.
