1 Claim.
the bolt shown in elevation. Figure 2 is a bottom view of nut and the clip that locks the nut, the bolt being shown in section. Figure 3 is a top view of a modified form of lock with the nut in section. Figure 4 is a longitudinal central section through Figure 3.
In the drawing I show a blade Ill and a blade ll pivotally held together by a bolt I2, the bolt having a fiat side I3 and the hole in one blade, such as the blade I0, having a flat side M to cause the blade and bolt to swing together.
The nut I5 is screwed on to the threaded end of the bolt and has a circular part 16. The nut shown has a head I! extending beyond the circular part and having an angular edge for receiving a wrench although this head canbe dispensed with. The blade I is provided with a recess or hole l8.
A wire clip is used for locking the nut in adjusted position. The clip consists of a single piece of wire l9 formed at one end into a loop 2|) and at the other end into a stud 2|. The stud 2| fits into the recess l8 and the loop 20 encircles the circular part of the nut to hold it in adjusted positions. The circular part l6 may be provided with a rough exterior face or made irregular in other ways although a circular portion is preferred because of easy manufacture.
When the device is to be used the bolt and blades are assembled. The clip is then placed with the stud 2| in the recess l8 and the loop 20 around the bolt. The nut is then placed on the bolt and screwed down. The circular part l6, which is slightly larger in diameter than the diameter of the inside of the loop 20 engages and spreads the loop. This is easily done in the case of round wire as the first contact of the part IS with the wire loop is on the rounded part of the wire and acts as a cam in spreading the loop. As the nut is screwed down the tension by the loop increases and the function acts to hold the nut against rotatable movement relative to the bolt and relative to the blade Ill.
tension established on By this device the a pair of shears is easily regulated and such regulation is maintained.
In Figures 3 and 4 I the same as in Figures show a modified form of nut lock. In these views the bolt and nut are 1 and 2 but I provide a clip with a loop 22 which encircles the nut I and has two projecting bent to form a stud 24.
I claim:
clip having a loop on one end, said loop having a normal inside diameter slightly less than the diameter of the circular part of the nut, the blade having a recess in it, the wire having its other end formed into a stud toenter the recess and act to hold the clip against turning when the nut is screwed on the bolt and the circular part of the nut spreads the loop into gripping relation with the nut, said clip being of round wire so that the rounded part of the wire will act as a cam when engaged by the circular part to spread the loop and said loop being only a single turn and the nut having a head extending beyond said circular part in confining relation over said single turn of round wire and whereby free continuous adjustment of the nut in both directions and locking in all such positions of adjustment is provided.
CHARLES J. DALLEY.
