Application filed 31115 23, 1914. Serial No. 852,532.

To all 157i omit mayconcern Be it known that I, SHERMAN Jones, a citizen of the United States, and resident of Newark, in the county of Essex and State of New Jersey, 'haveinvented certain new and useful Improvements in Linemens.

Tools, of which the following is a fication.

My 1nvent1on relates to new and useful speciimprovements in linemens tools, and has for its objecta device for bending wire cable around insulators, thimbles, anchors and the like prior to applying clamps for permanently fastening said insulators, &c., in position.

In the accompanying drawings, Figure 1 shows plan view of my improved tool, holding an insulator, wire cable and clamp. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a plan view of the tool in an open position with the cable threaded through the insulator and fastened ready for bending. Fi l is a perspective view enlarged of the holder for porcelain or vitreous insulators. Fig. 5 is a sectional enlarged view of jaws on dash and dot line XX of Fig. 3. Fig. 6 is a plan view of the head of the tool fitted for a thimble attached to a strain insulator, and Fig. 7 is an enlar 'ed perspective view of a holder suited for thimbles, &c., as shown in Fig. 6.

Similar reference characters denote like parts in the several views.

Heretofore it has been customary for linemen, when applying insulators, to bend the cable by hand and hold it firmly during the clamping operation. It requires two men to handle the ends, is hard upon the hands and somewhat dangerous. To overcome this condition, T provide the folding tool shown; it consists of two handles, 1, 2, duplicates of each other (except that they are right and loft.) and are flattened as at 4 near the jointed end, the handles being offset at 4: as shown. The ends are pierced with a hole. 5, for. the passage of a screw stud, 6, which forms a hinge; and this stud extends downward from the holder, 7, which holds the insulator, 8. A wing nut, 9. fastens the stud, 6, and holder in place. Near the flattened part of each handle a groove. 10, is provided for the cable, 11. The jaw, 12 is a plate with an extension, 12; at right angles, which extension enters the groove as shown in Fig. 5, and presses down on the cable when the ban dle screw, 16, isa'dvanced, this handle being threaded into the handle, 1, 2, of the tool as shown. i

For holding a vitreous insulator, I prefer to use a holder, shown in detail in Fig. 4 the ends, 7, 7", being bent upwardly and curved to suit. For strain insulators, 17, which are usually of a compressed insulating material with metal eyes extending therefrom, I prefer to use a block, 18, shown in Fig. 7, which is recessed at 18, for holding the eye, 17, and a thimble, 19; and a turnbutton, 20, holds the thimble in place during the operation of threading and bending the cable. The blocks shown in removable from the arms, so that either can be used as may be required. A handle clamp, 21, holds the handles together during the operation of attaching and securing the clamp, 22, on the cable for permanent fastening.

The operation is as follows: When an insulator has been placed in the holder, the handles are opened as shown in Fig. 3 and the end of the cable is threaded or passed through the insulator and fastened by means of the jaws on both of the handles, the pressure however being such that when the handles are advanced toward each other, or closed, the cable will be permitted to slide and make up for any extra length due to the size of insulator and curves. hen the handles are tightly closed a clamp, 21. can be slipped over the ends. The cable will be properly bent and separated just enough to permit the usual wire clamp, 22, to be fastoned. The handle screws, 16, are then loos sued, the clamp, 21. is slipped ofi and the tool removed from the cable.

For forming a loop around a th mble, the operation is substantially as described it being understood that the proper holder has been positioned for holding the said thimble in place, as shown in Fig. 6.

What I claim is:

1. A tool comprising a pair of pivotalh connected handles. adjustable cable gripping jaws long tud nally arranged upon each of the said handles and positioned in ax al alinement with each other when the handles are open and in parallelism when the device is in its closed position.

2. A tool comprising a pair of pivoted handles having flattened and offset end portions and provided with longitud nal grooves positioned in axial alinement with each other when the handles are open and in parallel- Figs. at and 7 are ism when the device is in its closed position, and adjustable cable-engaging clamping jaws fitted into the said grooves.

3. In a linemans tool as described, a pair of handles adapted for pivotal connection,

each handle being flattened and offset near the pivoted end and provided with a groove, and a jaw fitted in said groove, means for adjusting said jaw, in combination with a holder provided with means for pivotally connecting said pair of handles together.

4. A tool comprising a pair of pivotally connected handles, adjustable cable gripping jaws longitudinally arranged upon each of SHERMAN JONES.
