CHARLEY MERRITT MOFATRIDGE, OF MORAVIA, IOWA.

WIRE-'BENDER.

SPECIFICATION forming part of Letters Patent No. 734 350, dated July 21 1903.

Application filed November 4, 1902 Serial No. 130,034. (No model.)

ence marked thereon, which form a part of this specification.

This invention relates particularly to a device for bending wires to a suitable shape to form ties to attach electric conducting-wires to insulators, the wires so formed being what are known as tie-wires.

It has been found that tie-wires of considerable size are not easily bent by hand or pincers and when so bent are apt to be uneven and fit the insulator poorly. The object of my invention is to form a simple device which will remedy these defects and bend tie-wires to a desired exact form quicklyand easily.

The device comprises a former secured to a base-board and a pair of levers which will bend the wire around the former, and is illustrated in the accompanying drawings, in which-- Figure 1 is a plan view before the wire is bent. Fig. 2 is a similar view after the wire is bent. Fig. 3 is a side elevation.

Referring specifically t0 the drawings, the base-board is indicated at 6. The formerblock 7 is secured to this board, and the block has preferably a groove 7 to. hold the wire.

8 indicates a pair oflevers, 'whicharepivoted to the top of the block conveniently by the bolt 7", by which the block is secured to the base-board. The levers have studs 8 depending therefrom, and the studs are preferably headed, as at 8", to prevent the wire slipping. They are adjustable on the levers to vary the distance from the pivot by means of slots 8, the ends of the studs being screwthreaded and provided with binding-nuts 8 above and below the lovers, whereby the studs may be adjusted in the slots to the desired position.

To give. the free ends of the' tie a desirable outward flare, a block 9 is employed. This is secured to the base-board andis provided with grooves 9 to receive and shape the wire.

In operation a piece of wire the desired length is placed between the back of the former-block and the studs, as shown in Fig.

1. The levers are then brought around oppositely, bending the wire around the former, which, it may be understod, is the same size as the insulators on which the ties are to be the block 9 they are caused to flare to the desired extent by the pressure of the levers at the neck of the loop. The ties maythus be formed rapidly and true to the exact shape required to fit the insulators and avoiding the laborious and unsatisfactory bending by hand or pincers.

What I claim is Awire-bender comprising a former-block, and a reverse-bending block' spaced from the former, and a pair of oppositely-working 1evers fulcrumed 0n the former-block and having depending studs bending the wire around the former and between the blocks, substantially as described.

In testimony whereof I 'affi'x'my signature in presence of two Witnesses.
