Specification of Letters Patent.

Patented Sept. 29, 1914.

Application fled November 28, 1910. serial R0. 594,441.

To all whom it may concern:-

Be it known that I, ELnEirr H. CARROLL, a citizen of the United States, residing at lvorcesteigin the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Wire-Gripping Mechanism, of which the following isa specification, accompanied by drawings forming a part of the same.

The objects of my invention are to provide a wire gripping mechanism designed to be used in connection with a rotating wire drawing block for holding the end of the wire at the beginning of the drawing operation, having means by which the aws of the gripping mechanism may he opened by the attendants, and being capable ofautomaticall seizing and holding the wire. These 0 jects, among others, I accomplish by means of the construction and arrangement of parts as hereinafter described and pointed out in the annexed claims.

in the accompanying drawings, Figure 1 represents a sideelevation of a wire drawing block provided with agripping mechanism embodying my invention. Fig. 2 is a detached perspective view of the gripping mechanism with the jaws in a closed position. Fig. 3 is a detached perspective view with the jaws o ened, and Fig. tis a sectional View on t e plane of the broken line M, Fig. 3.

Similar reference characters refer to similar parts in the different figures.

Referring to the accompanying drawings, 1 denotes a rotatable wire drawing block to which is connected by a chain 2 a wire gripping mechanism 3 embodying my present improvement. The gripping mechanism 3 comprises a pair of opposing jaws 4 and 5' pivotallyconnected on opposite sides by links 6, 7, and 8, 9. Extending upwardly from the jaw 4 is an arm 10 and extending upwardly from the jaw 5 is an arm 11, said arms being preferably curved in order that the arm 10 may fit the palm of the hand and the arm 11 be conveniently grasped by the fingers, as shown in Fig. 3, for the purpose of bringing the arms together and rocking the jaw 5 on its pivotal connection with the jaw 4 to separate the jaws for the inscrtion of the end of the wire between them.

Between the: arms 10 and 11 I interposea spring 12 having its ends bearing against tension applied to hold the arms normally separated with the jaws 4 and 5 in a closed posit on,- as shown in Fig. The face 13 of the aw 4 1s preferably smooth, while the face 14 of the jaw 5 is preferably toothed or serrated. The toothed face 14 is preferably formed on. a detachable bar 15, having apro ection 16 interlocking the jaw 5 to pre-.

vent the longitudinal movement of the'detachable bar 15. The bar 15 is held in place by means of a screw 17. In order to insert the. end of the wire between the jaws 4 and 5 the arms 10 and 11 are compressed by. hand, causing the jaw 5 to be rocked on the links 6, 7 and 8, 9 the ends of which links are pivotally connected to said jaws and separated fromthe jaw 4, as shown in Fig. 3, sufficiently to allow the nsertion of the end of the wire 18, Fig. 1. When the arms" 10 and 11 are released, the spring will reverse the motion of the jaw 5 and bring the 0 posing faces of the jaws firmly against t e end of'- the wire. The distance between the pivotal centers of the links 7 and 9 is slightly less than the distance between the pivotal centers of the links 6 and 8, so that when the opposing faces of the jaws are in their closed position, ,as shown in Fig. 2, the opposingfaces will be slightly divergent, or separated at their outer ends w ile in contact at their inner ends, so that pressure is first applied to the end of the wire 18.," When the wire drawing block 1 is started and a strain .exerted upon the wire 18, the teeth carried b the jaw 5 will be drawn into the body of t e wire atgradually decreasing de ths from the inner toward the outer ends 0 the V to receive a hook or link ofthe chain 2.

I claim,

1. Awire gripping mechanism, comprising a air of opposing gripping jaws, links pivota ly connected to said jaws, and upwardly extending arms on each of said jaws adapted to be compressed by hand for opening the jaws. a

2. In a wire gripping mechanism, the combination of a pair of opposing gripping jaws,'links.pivota 1y connected to Said jaws, upturned arms pro ecting from each of said jaws, and a spring interposed between said of wire gripping jaws, links pivotally conarms to separate them and hold the jaws in nected to each of said jaws, and means a normally closed position. adapted to be operated to open said jaws,

3. In a wire gripping mechanism, a pair comprising an arm extending from each of 15 5 of wire gripping jaws, a pair of links each I said jaws.

pivotally connected to said jaws, and means Dated this 23rd day of November 1910. extending from each one of said jaws in cooperating relation to the means extending ELBERT CARROLL from the other of said jaws to provide for Witnesses: 10 the opening of said jaws. WILLARD A, WINN,

4. In a wire gripping mechanism, a pair F RANK M. LORD.
