KEY FOR LOOKING BOLTS, 80c.

SPECIFICATION forming part of Letters Patent No. 248,067, dated October 11, 1881. Application filed June 23 1881. (Model.)

To all whom it may concern Be it known that I, GEORGE B. TAYLOR, of New Brunswick, New Jersey, have invented an Improvement in Keys or Gibs for Locking Bolts into Position, of which the following is a specification. I

My invention consists in so constructing a key or gib, usually used for looking or holding a bolt into position, that no jar or shake causes to the same to fall out; and it consists of the peculiar construction ot'the gib, as shown, in combination with a spring.

It will be seen by reference to the drawings that the purpose of the bolt and gib illustrated therein is to pivotally connect the forked standard and the lever. The bolt, key, and spring, however, may be used for various purposes.

In the drawingsY Figure 1 represents a side view of a; ratchet or lever containing my inven- 2o lion; Fig. 2, sectional view on line as .r, Fig. 1; and Fig. 3 is aside view of my gib or key.

In the drawings, A is a bolt, having head a, and inits other end a key-hole, b. B is a spring. I show this as a spiral spring in the drawings.

' Any equivalent will serve the purpose.

D is my gib or key. This key is so constructed that it has the recess d and projection a.

It is now evident that if the spring placed on the upper part of the bolt, the pressure 0t which serves to drive the bolt out, be pressed in the bolt will pass far enough through the hole to allow the keyhole d to appear. The key-hole is larger than the key D, which is slipped into the key-hole till the nib or projection 6 has passed the side of the bolt, and the 5 pressure being removed the spring presses against the head of the bolt and pushes the bolt tight against the key. As the bolt now rests in the recess d the projections h h'hold the said key from slipping. At the same time 40 the projection 6 has been forced into the hole of the sleeve of metal or other body through which the bolt A passes, as shown in Fig. 2 at g, and thus the key is held, both in front and back, from slipping out.

The key may he made of any metal suitable for the purpose.

What I claim, and desire to secure byLetters Patent, is-

1. A bolt-key having a recess, (1, in combination with a slotted bolt, and a spring, as and for the purposes specified.

2. A bolt-key having a recess, 0?, and projection 0 opposite thereto, in combination with a slotted bolt, and aspring, as and forthe purpose specified.
