TOOL FOR TWISTING WIRE-JOINTS.

To (LZZ whom it may concern:

Be it known that I, CLARENCE E. Cook, a citizen of the United States of America, re siding at Chicago, in the county of Cook and State of Illinois, have invented a new and useful T 001 for Twisting Wire-Joints, of which the following is a specification, reference being had to the accompanying drawings, illustrating same.

My invention relates to a device for making wire joints, either between a air of bare wires or between a wire-joint s eeve and a pair of wires inserted therein.

The principal objects of my invention are E to provide a tool for twisting wire joints which will firmly hold the wires, or the wires and the sleeve, to be connected, and not spring apart during the operation of twisting the joint; to rovide such a device which may be read' y and easily 7 applied to the wires or the sleeve to be twisted; to provide such a device which may be used for twisting several sizes of wires or sleeves and in which the leverage on the clamping jaws is practi- J. cally the same for all of the different sizes; to

provide such a device which does not injure the galvanizing on the wire that is being twisted, or the tinning on iron wire-joint sleeves; and to provide simplicity of construction, lightness, and cheapness of manufacture in such a device.

Other objects will be apparent from the following specification.

In the drawings, Figure 1 is a side eleva- 11 tion of the preferred form of the device of the ii is pivoted a clamping member 4, at 5, having a handle portion 6 thereon adapted to be gripped in the hand with the handle portion 2 to force the clamping jaw 4 against its mate, as will be hereinafter described. Be-

\1 tween the side portions 3 3 is also pivoted a wheel 7, at 8, having a number of fiat faces 11 11 on the exterior portion thereof, each adapted to coperate with the clamping jaw 4 when the wheel 7 is turned to the proper position. Each of the fiat faces 11 11 on the Specification of Letters Patent.

wheel 7' is provided with a double groove 9 therein shaped to receive and fit a pair of wires or a wire-joint sleeve, the grooves 9 9 in the various faces being of different sizes, preferably as shown, to accommodate various sizes of wires and wire-joint sleeves.

On the clamping jaw 4 is provided a pro j ecting portion 10 extending across the jaw 4 and adapted to fit in between the wires to be twisted, or to press against the wire-joint sleeve between the wires therein, to properly hold the wires or the sleeve and thus firmly clamp the same in place while beingtwisted.

On at least one of the side portions 3 3 is provided a tongue 12 formed out of the material of the portion 3 and projecting inwardly so as to fit in any one of the depressions 13 13 provided in the wheel 7 to hold the latter in the proper position relatively to the jaw 4 when the wheel 7. is turned so that the proper sized double groove 9 registers with the clamping jaw 4. Thus it will be seen that the wheel 7 can be readily set so as to permit the use of any of the various double grooves 9 9 thereof, and locked in this position as long as it is desired to use one size of double groove 9. By the arrangement 12 13, the wheel 7 in being set relatively to the jaw 4 must be turned in the direction of arrow 14, because tongue portion 12 prevents wheel 7 from turning in the opposite direc tion. The tongue portion 12 is formed in this manner so that when the jaws 4 and 11 are opened and the tool is placed over the wires or sleeve, the wheel 7 will not turn out of position due to pushing on the handle portions 2 and 6 before the jaw 4 is closed down on the jaw 11.

With the tool of this present invention the wires to be twisted enter between the clamping jaws from the end of the tool opposite the handle portions.

When it is desired to twist a wire joint a pair of the tools shown in the drawings of this invention are used, one at each end of the joint to be twisted, each having its handle portions 2 and 6 spread apart until the wires or the end of the wire-joint sleeve can be inserted into the double groove 9 between the jaws 4 and 11. When the wires or the sleeve are thus inserted into the double groove 9 the handle portions 2 and 6 are squeezed together, which tightly clamps the wires or the sleeve in the double groove 9, the handle portion 6 being then looked relatively to the handle portion 2 by a link 15 which is carried hjv the handle portion 2 and slipped over the end of the handle portion 6 into a small groove across the outer surface of the end of the handle portion 6, preferahlv as shovrn. then both of the tools are thus secured to the wires or to the sleeve to he twisted, they are then twisted in opposite directions until the joint is twisted suflicientlv, generally turns ra'here v-Jire-joint sleeves are used. In twisting the joint any force from the latter tending to spread. the jams l and 11 apart has very little effect in separating these because t re joint is very close to the pivots 5 and 8 and not very iuch out of a plane including the longitudil Wires or sleeves uhich can he waisted. hv the tool.

On the portion t is provided a head 16 shaped and adapted to he used a hammer. The end of the handle portion 6 is formed as at 17 to he used as a SCl'6'.-.' driver. This screw driver portion 17 projects out beyond the end of the handle 2 and can therefore he used as a sore driver either 1-. hen the handle portions 2 and are locked together or are separated. The hammer and the scre=.-. drlver 17 are found to he very useful, espe cially in the absence of various other tools.

The douhle moves 9 9 and. the clamping surface of the 4': are preferably made smooth so as not to injure the galvanizing or j the tlnning on the surface of the ires or sleeve being twisted.

the javv 4, may he rounded otl' if desired so the corner portions of the clamping ja I wish it to he understood that the wheel 7 may have any nrnnher of faces 1]. 11 desired, such 6, S, or any other nuinher.

I do not v-xish to limit this invention to the exact details of construction herein sho 1, as various modifications in such adevice may he nrade without departing from the scope of the appended claims.
