3 Claims.

The present invention relates to new and useful improvements in tools for removing insulators from electric fences and from other places to which the insulator may be attached, the primary object of the present invention being to provide a tool of this character adapted for engaging and removing the nail employed for holding the insulator in position without danger of breaking the insulator.

A further object of the invention is to provide a tool of this character of simple and practical construction, which is strong and durable, efficient and reliable in performance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended. 7

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout and in which:

Figure 1 is a side elevational view,

Figure 2 is a top plan view.

Figure 3 is a front elevational view.

Figure 4 is a Vertical sectional view taken substantially on a line 4-4 of Figure 2.

Figure 5 is a perspective view of the wire jaw employed for engaging one side of the nail, and

Figures 6 and 7 are top plan view of modified forms of base members adapted for engaging insulators of various shapes.

Referring now to the drawings in detail andv with particular reference to Figures 1 to 5, inclusive, the numeral 5 designates a base mem her having an opening 6 therein adapted for receiving the insulator l of conventional construction, which is usually secured to a supporting structure by a nail 8 under the head 9 of which a washer i ispositioned.

A post ll rises from the base adjacent its rear end, the underside of the base immediately beneath the post having a spur l2 formed thereon adapted to bite into the work to prevent slipping of the base during operation. Projecting from the rear of the base beyond the post I! is a heel portion [3. i

The upper end of the post H terminates in spaced upstanding ears I4 having a pin extending therebetween and freely positioned in an edge [9 adapted for engagement under the head 9 of the nail.

A second handle member 20 has its front end bifurcated as shown at 2! for receiving the lower edge of the handle member Fl for pivotally mounting the same thereon by means of a trans verse pin 22. The front end of the handle 20 extends angularly as shown at 23 forwardly of the pivot 22' and the furcations thereof are formed with openings 24 adapted to receive the inturned ends 25 of a U-shaped wire member 26, the bite portion of the'wire member having a jaw v21 mounted thereon formed with a knife edge 28 of arcuate shape and adapted to engage the nail under the head thereof at a side opposite from the jaw l8. The edge of the jaw opposite from the blade 28 may be formed with a flat fingergrip extension 29 to guide the jaw into its-position for engaging under the head 9 of the nail.

' In Figures 6 and '7 of the drawings, I have illustrated modified forms of base members, Figure 6 representing a base 361 having a curved yoke 3| for engaging the insulator while the base 32,. shown in Figure 7 of the drawings, is provided with a U-shaped yoke 33 having its sides disposed in parallelism and adapted for engaging an insulator of complementary shape.

In the operation of the device the jaws l8 and 21 are adapted to engage under the head of the nail and upon an upward movement of the handle 20 relative to the handle I7, the jaw 21 will be pulled rearwardly to ride under the head 9 therebyloosening the nail, and upon exerting a downward pressure on the handle I! the nail will be raised upwardly and removed from the insulator. During the downward movement of the handle I! the same is also urged forwardly so that the pin [5 will travel along the slot I6 and thuskeep the jaw l8 in the plane of the axis of the nail to prevent bending of the nail and eliminate danger of cracking or breaking the insulator.

It is believed the details of construction and manner of use of the device will be readily understood from the foregoing without further detailed explanation. 1

Having thus described the invention what I claim is:

1. A nail puller comprising a base, a handle pivoted on the base, and having a jaw adapted to engage under the head of the nail at one side thereof, a handle pivoted to the first-named handle, and a jaw pivotally attached to the second-named handle and adapted for movement under the head of the nail at a side thereof opposite from the first-named jaw upon a predetermined movement of the second named handle.

2. A nail puller comprising a base, a handle pivoted on the base, and having a jaw adapted to engage under the head of the nail at one side thereof, a handle pivoted to the first-named handle, a U-shaped wire member having its ends attached to the .second-namedhanfle. and a second Jaw carried at the bight portion of the member and adapted for engaging under the head of the nail at a side thereof opposite from the first jaw.

3. A nail puller comprising a base, a pair of handles, a pin and slot pivotal connection between one handle and the base providing a backand-forth movement for the handle, the other handle being pivoted to the first-named handle. and jaws carried by said handles and adapted to engage under the head of the nail at opposite 10 sides thereof.
