WILLIAM G. ennn, OF SYRACUSE, new YORK.

KEY-FASTENER.

SPECIFICATION forming part of Letters Patent No. 347,170, dated August 10,1886.

Application filed December 30, 1885. Serial No. 187,113. (No model.)

TO all whom it may concern:

Be it known that I, WILLIAM C. GERE, of Syracuse, in the county of Onondaga, in the {State of New York, have invented new and useful Improvements in Key-Fasteners, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The object of this invention is to prevent a key from being turned in the look from the side of thedoor opposite to that at which the key is inserted, and thereby guard against burglarious opening of the door; and the invention consists, essentially, in the combination, with a key, of one or more guard-arms connected to the shank of the key, movable laterally therefrom, and an 'escutcheon provided with seats for the reception of said arms to hold the same, and thus prevent the key from turning, as hereinafter more fully described, and set'forth in the claims.

In the annexed drawings, Figure I is a transverse section of an escutcheon, with the key locked thereon to prevent. it from turning. Fig. II is-a face viewof the same. Fig. III is a detached side viewof the key in its folded condition, and Fig. IV is an edge View of the latter. c

Similar letters of reference indicate corresponding parts.

A represents the shank of a door-key, which shank may be either round, flat, or any other ordinary form, though I prefer to make it fiat for at least part way the length thereof from the outer end back, for the purpose of folding more compactly thereon the guard-arms a a, one or more of which I pivot on the shank A, so as to swing laterally orat right angles therefrom, as represented by full lines in Figs. I and II of the drawings, or into line with the shank, either outward from the end thereof, to

serve as a handle for turning the key, as shown by dotted lines in Fig. I of the drawings, or back against the sides of the shank, as shown in Figs. III and IV of the drawings, to render the key more compact and convenient for car'- rying in the pocket. On the free ends of the armsa a, I pivot lugsb b, which can be turned back at right angles from the arms, to engage notches or depressed seats at a in the face of the escutcheon O, as represented in Fig. I of the drawings. Said escutcheon, being firmly secured to the door in any of the usual and well-known manners, serves to prevent the key from turning when the aforesaid lugs b b are in engagement with the notches a n.

I do not limit myself to the pivoting of the lugs 12 b on the arms a a, as it is obvious that said lugs may be rigidly attached to the arms and still engage with the notches n n. I merely prefer to pivot said lugs forthe purpose of allowing the key to fold more compactly. Furthermore, said lugs b b may be entirely dispensed with and the ends of the arms a a swung back far enough to engage the notches or seats of the escutcheon.

What I claim as my invention is 1. The combination, with a key having one or more guard-arms connected to the shank thereof, and movable laterally therefrom, of an escutcheon provided with seats for the reception of said arms to hold the same, and thus prevent the key from turning, substantially as set forth.

2. A key having the arms a a pivoted on the shank thereof to swing at right angles therefrom, and the lugs b b pivoted to said arms, in combination with the escutcheon 0, provided with notches a n, substantially as and for the purpose set forth.

In testimony whereof I havehereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 28th day of December, 1885,

WILLIAM G. ones. [1 s.]
