SEEGSCFIGATION forming part of Letters Patent No. 678,583, dated July 1-6, 1931. Application filed January 29,1900. Serial No. 3,118. (No model.)

To ctZZ whom it may concern.-

Be it known that I, WILLARD A. OSLEY, a citizen of the United States, and a resident of Vethersfield, in the county of Hartford and State of Connecticut, have invented a certain new and useful Improvement in Pliers, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

My invention relates to the class of devices commonly known as pliers, and more particularly to the specific class of pliers adapted to be used in bending, cutting, and working wire.

The object of my invention is to produce a tool of this class which while it has all the advantages of those of the prior art and is provided with gripping-jaws and cutters is also provided with a means for forming a union or connection between two wires by winding tliem about each other.

To this end my'invention consists in the device as a whole, in the combination of the parts, and in the details of such parts and their combination, as hereinafter described, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side view of a pair of pliers embodying my improvement. Fig. 2 is a top or plan view of part of the jaws and appurtenant parts. Fig. 3 is a plan view of the lower jaw, the handle being broken away. Fig. 4 is a view in side elevation of a modified form of my invention. Fig. 5 is a top or plan view of the device shown in Fig. 4.

In the accompanying drawings the letter a denotes a pair of pincers or pliers embodying myinvention and consisting of jaws Z1 Z2, pivoted, as at c, and provided with handles d d and cutters e 6. These parts may be of any suitable and well-known construction and form no part of my present invention except as they are combined with it. In practice a device of this sort, while it is applicable to many kinds of work, is especially useful in bending, cutting, and working wire.

It is often necessary, as in working on wire as it it is commonly used in electrical work, to splice two pieces of the wire together, and in such cases it is very desirable to make a firm tight joint, insuring a perfect electrical contact, at the same time having a joint of such mechanical construction as will stand the strains. The most common method of connecting wires where no separate piece, as a sleeve or union, is used is that known to those familiar with the art as the VVestern- Union connection. This connection is made by first bringing the two wires into parallel relation with each other, then holding them together at a point intermediate of the overlapping ends one of the end portions is turned back at right angles to the line of the two wires, and then wound or wrapped about the other wire. The end of this other wire is then treated in a similar manner, and as a final finish the whole joint is poured with solder until an absolutely tight joint is made. These joints have usually been made by gripping the outturned end of one of the wires with the gripping-jaws of the pliers, and by then resting the side of the pliers against the wires and turning them about the wires while the end of the wire between the jaws is firmly held this wire is partially wrapped about the main wire. This gripping and twisting operation must of course be repeated until both ends are completely wound down about the opposite wire. In my improved device I have provided means whereby. each of the end portions may be wrapped about the opposite wire by simply revolving the pliers about the wire without necessitating their removal until the end has been completely wound down into place. To accomplish this result, Iprovide a transverse openingf between the jaws h b, and in operative relation to this opening is located a twisting-block There are preferably two of these blocks g, one being located on each of the jaws b b, so that the device will operate equally well whether turned to the right or to the left with reference to the transverse opening f. As shown in Figs. 1, 2, and 3, these twisting-blocks are located at the sides of their respective jaws and are provided with angular extensions g fitting suitablyformed mortises locatedin the jaws b b. The mortises and corresponding extensions are tapered slightly from the inner to the outer side of the jaw, as clearly shown by comparison of Figs. 2 and 3. By this construction the blocks may be inserted in the mortises ICO when the jaws of the pliers are in their full open position, and the greater the force. applied to the lower side of the blocks, as at y the tighter the blocks will be held in their mortises. These blocks are preferably formed long enough to allow the end g to come into contact with the inner surface of the opposite jaw, thus providing a convenient form-of stop for preventing so close a contact of the cutters e e as to soar or breakthem. At the side of the blocks g adjacent to the transverse opening is formed a guide grove g, which serves to guide the wire and hold it in proper position dnrin g the winding operation. The side of the block, as well as the groove formed in it, is arranged at an angle across the axis of the transverse opening f and is of such a length as to reach entirely across the opening from side to side. It will be readily seen that with this construction wires of different diameters may be wound equally well.

While the twisting-blocks shown in Figs. 1, 2, and 3 are removable and project from the side of the gripping-jaws, the invention is not limited to this precise construction and contemplates the use ofa block with its working face grooved and arranged at an angle across the transverse opening in the pivoted members, whether the blocks be separable pieces or formed integral with the pivoted members. Itis of course immaterial also just where the twisting-block is located so long as its working face lies adjacent to the opening between the pivoted members.

In Figs. 4 and 5 is shown a modification of the device thus far described. In this form of the device the jaws 1 2, pivoted at 3, having ing cutters 6 7 and provided with handles 4 5, are arranged as described above. A transverse opening is also provided between the jaws, as at 8. The twisting-blocks in this form instead of being formed by pieces set in or formed integral with the jaws consists of a recess 9, formed in the jaw and having its working face arranged at an angle across the opening 8. In this form of the device a movable pin 10 is arranged to be projected across themouth of the opening 11, thus confining the movement of the wire or like part which is being operated upon by the inclined surface 12. This pin 10 is so arranged that one end of it comes in contact with a shoulder 13 when the pliers are being closed, thus forcing it forward, where it will remain locked iintilthe jaws are again opened a suficient distance to permit it to drop back into the recess 14, formed in the jaw 1. If desired, a spring may be used to positively withdraw the pin, as suf ficiently shown in dotted outline in Fig. 5.

The operation of the device is as follows: The pliers are placed with the transverse opening encircling the wires to be wound. The end of one of the wires is then bent at right angles to the axis of the transverse opening and placed in engagement with the groove in the side of the twisting-block. revolving the handles about the wires it is obvious that the wire which is in contact with the surface of the block will be wound in a close spiral about the other wire.

Having described my invention, my claim is 1. In combination, in a wire-working tool, comprising a pair of pivoted members including cutting-jaws and handles, a transverse opening located between the pivoted members, and twisting-blocks removably secured to the pivoted members and provided with a grooved working face adapted to cooperate with the transverse opening, said grooved working face being angularly disposed to and extending across the axis of the transverse opening.

2. In combination, in a wire-working tool, including pivoted gripping-jaws and cutters, a transverse opening located between and formed in the jaws, twisting-blocks removably attached to the gripping-jaws and provided with a grooved working fade adapted to cooperate with the transverse opening in the jaws, said grooved working face being arranged at an angle across the axis of the transverse opening, and handles for operating the several parts.

3. In combination, in a device of the class specified, a pairof pivoted jaws provided with handles, a transverse openinglocated between and formed in the jaws, a recess formed in operative relation to the transverse opening and adapted to serve as a guide for the stock operated upon, and means for positively confining the work within the recess.
