KEY-FASTENER.

SPECIFICATION forming part of Letters Patent No. 366,150, dated July 5, 1887.

Application filed May 1 1, 1887. Serial No. 237,907. (No model.)

To all whom it may concern:

Be it known that I, JAMES BUSFIELD, a citizen of the UnitedStates, residing at Haw erhill, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Key-Fasteners, of which the following is a specification.

The object of my invention is to produce a key'fastener that can readily be secured to a [0 door by a single screw, and which, when applied to the key, will securely hold the same, so that it will be impossible to turn the key from theoutside, and when not in use will li flat against the door out of the way.

The invention consists of a furcated wire having its outer ends bent over and secured at its inner end to the door by a slotted plate, the wire forming a spring, so that it can be compressed to pass through the bow of the key. Referring to the accompanying drawings, Figure 1 represents a perspective view of a portion of a door stile with lock, and a keyfastener embodying my invention as applied to the key. Fig. 2 is a similar View showing I the position of the fastener when not in use.

Fig. 3 is a horizontal section taken 011 line no at of Fig. 2. I

A represents the door-stile, B the lock, 0 the knob, and D the key.

E is a metal plate provided with a slot or groove, 0, and secured to the door-stile A by a screw, F. V

G is a furcated wire secured to the door by the plate E, the wire G being free to move up 5 and down in the slot or groove 0. The furcated wire G is bent to the form shown-that is, contracted at g to form a spring and bent over at its outer ends, h h.

To apply the key-fastcner the plate E is first secured to the door-stile A in the proper position by the screw F. The two ends of the furcated wire are then taken between. the finger and thumb and compressed The wire is then pushed up so thatits outer ends, h 71', will pass through the bow D of the key D, when the key will be firmly secured, as shown in Fig. l, the bent-over ends h preventing it from slipping out of the bow D". \Vhen it is desired to release the key, the ends of the wire are again compressed and the wire pushed down,whenthe outerends, h,will pass through the bow D and the wire G will fall into the position shown in Fig. 2.

To hold the wire down against the door stile A, I form a groove, f, on each side at the lower end of the plate E, (see Fig. 3,) so that when the wire G is placed down it will snap over the edges of the plate E and be held in the grooves f, as shown in Fig. 2, so that it will not swing out when the door is opened or shut.

It will be seen that by means of the slot or groove 6 the wire G can be raised or lowered, according as it is required to attach it to or detach it from the key.

What I claim as my invention is- The plate E, provided with a slot or groove, 0, and grooves ff, in combination with the furcated spring-wire G, contracted at g, and having its outer ends, h, bent over, substantially as and for the purposes set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

' JAMES BUSFIELD.
