Application June 30, 1945, Serial No. 602,510

1 Claim. 1

My present invention, in its broad aspect, has to do with improvements in tools for pulling the insulators of electric Wire fences. It has been found difficult to pull the insulators of Wire fences, and my present invention both securely clamps about an insulator to be removed and functions as a pry to give the necessary leverage to detach it. My device is simple and sturdy and has no parts likely to become broken or get out of order under hard and continuous usage, and it may be manufactured and sold at relatively small cost.

Other and equally important objects and advantages of my invention will be apparent from the following description and drawings, wherein I have illustrated a preferred form of my invention, in which:

Figure 1 is a side view;

Figure 2 is a top plan view, and

Figure 3 is a section on the line 3-3 of Fig-. ure 2.

In the drawings, wherein like characters of reference are used to designate like or similar arts:

p The numerals I and 2 designate the handles of my device, which are preferably formed of suitable hard wood and have slightly tapered rounded grip parts 3, and the remaining parts of the handles 4 are substantially rectangular in cross-section, and are slightly tapered toward the ends as at 5. A strap hinge 6 connects the ends 5 of the handles and has parts i passing over the ends and parts 8 bent substantially at right-angles to the parts 1 and lying upon and attached to the tapered ends of the handles. Four bolts 9-two for each handle-connect the hinge to the handles. Back of the front end of the handles is an opening l formed by semicylindrical recesses. The wall of the opening, between its ends has a bead II. In operation, the handles are pivoted apart and the insulator l2 grasped in the opening in with the bead ll fitting in the slot. The handles are then pressed together and the tool raised, using the short end i3 as leverage, if desired, with the ends of the handles bearing against any convenient object and functioning as a fulcrum point after the manner of a pry bar.

I claim:

A tool for pulling a grooved insulator off its support comprising a pair of elongated members, each of said members having slightly tapered and rounded forward portions forming a hand-grip, said forward portions merging into slightly oppositely tapered and rectangular crosssectioned rearward portions, a strap hinge having a pair of strap-like members pivoted together with the portions of said strap-like members adjacent the pivoted parts abutting the rearmost ends of said rectangular portions of said members, end portions of said strap-like members being bent forwardly of said members and engaging the tapered sides of said rearward portions of said elongated members, means securing said end portions of said strap-like members to said elongated members to hingedly connect said elongated members together, opposed semi-cylindrical recesses in said rectangular rearward portions of said members, circular projections in said recesses intermediate the ends thereof, whereby a grooved insulator may be grasped by said members between said semicylindrical recesses at a point of inter-engagement between said circular projections and the groove of an insulator which may then be pulled from its support by utilizing the rearward portions of the elongated members as a fulcrum means.
