3,298,257 WIRE CLAMPING HAND GRIP James W. Goss, 410 South St. W., Warren, Ohio 44483 Filed Aug. 27, 1965, Ser. No. 483,279 6 Claims. (Cl. 81-3) The invention relates to a line puller and more particularly to a wire clamping hand grip for clamping and pulling wire and the like.

In the January 1965 edition of Auto and Flat Glass Journal, there was an article describing a method of removing Windshields from automobiles with the use of two vise grip pliers and a section of piano wire.

The Wire clamping hand grip comprising the subject matter of the present application was produced especially for the purpose of providing an inexpensive and eflicient substitute for the vise grip pliers in practicing said method of removing Windshields. However, it should be understood that the present invention is also equally well adapted for use in any place where a wire clamp or puller is required.

The primary object of the invention is to provide a simple, efficient and easily operated device in the form of a hand grip or handle having means therein for clamping the end portion of a wire or the like.

Another object of the invention is to provide a wire clamping hand grip in the form of tube of metal or the like through which the end portion of a wire may be inserted perpendicularly, with means within the tube for clamping the wire, whereby the tube may be used as a hand grip or handle for pulling upon the wire.

A further object of the invention is to provide a wire clamping hand grip of the character referred to in which a pair of rollers is located longitudinally within the tubular housing and means is provided therein for causing the rollers to clamp upon a wire located perpendicularly through the housing.

A still further object of the invention is the provision of such a wire clamping hand grip in which the tubular housing is of trapezoid cross-sectional shape with two oppositewalls thereof converging toward a third wall, and means for urging the rollers into engagement with said converging walls for clamping a wire therebetween.

It is also an object of the invention to provide a wire clamping hand grip of this type in which the rollers are loosely mounted upon a spaced pair of rods pivotally mounted within one end portion of the tubular housing with spring means for urging the other ends of the rods toward said third wall of the tubular housing to clamp a wire between the rollers.

It is another object of the invention to provide a wire clamping hand grip of the character referred to in which one end portion of one wall of the tubular housing is bent, at substantially 90, into the housing and provided with a spaced pair of openings within which the adjacent end portions of the rods are pivotally mounted, the other ends of the rods being connected together by a block having an aperture therethrough slidably received upon a pin in that end of the tubular housing, a spring being interposed between said block and the fourth wall of the housing for urging the rods toward the third wall thereof.

Finally, it is an object of the present invention to provide such a wire clamping hand grip in which the two spaced rods are in the form of a U-rod, the closed end of which extends out of the end of the tubular housing opposite to that in which the pivot is located.

The above objects together with others which will be apparent from the drawing and following description, or which may be late-r referred to, may be attained by constructing the improved wire clamping hand grip in the manner hereinafter described in detail and illustrated in the accompanying drawing, in which;

FIG. 1 is a perspective view of a wire clamping hand grip embodying the invention;

FIG. 2 is a vertical, longitudinal sectional view taken as on the line 2-2, FIG. 3;

FIG. 3 is a horizontal sectional view taken as on the line 33, FIG. 2; and

FIG. 4 is a transverse sectional view taken on the line 4-4, FIGS. 2 and 3.

Referring now more particularly to the embodiment of the invention illustrated in the drawing, in which similar numerals refer to similar parts throughout, the improved wire clamping hand grip includes a tubular housing indicated generally at 1. This housing may be formed of metal and may be in the form of aluminum extrusion.

The housing 1 may be in the form of trapezoid of keystone shape having the two opposite side walls 2 converging toward and joined at one of their edges to a third wall 3, a fourth wall 4 of greater width than the wall 3 being joined to the opposite edges: of the converging side walls 2.

One end portion of one wall (preferably the wall 3 as shown) is separated from the two adjacent walls and bent inward into the tube at about forming the bearing flange 5. A spaced pair of apertures 6 are formed in the flange 5, providing means for pivoting the ends of a pair of parallel rods 7 which may be the two legs of a U-rod indicated generally at 8, the closed end 9 of which protrudes from the opposite end of the housing 1.

The apertures 6 are of larger diameter than the rods or legs 7 of the U-rod so that the same may pivot freely therein. A block ltl is welded or otherwise connected to the rods or legs 7 near the protruding closed end 9.

The block 10 has an aperture 11 therein so that the same may be slidably received upon the pin 12 connected at opposite ends to the walls 3 and 4 of the tubular housing 1, as indicated at 13. This pin 12 is preferably slightly curved, forming an are drawn from the pivotal center of the rods or legs 7.

A spring 14 is interposed between the block 10 and the wall 4 of the tubular housing to urge the free ends of the rods or legs 7 toward the wall 3 of the tubular housing. A roller 15 is mounted upon each rod or leg 7. As shown in the drawing, the inside diameters of these rollers are larger than the diameters of the rods or legs 7.

An aperture 16 is centrally located in the wall 3 of the housing 1, and a similar aperture 17 is centrally located in the wall 4 thereof, so that one end portion of a wire 18, or the like, may be located perpendicularly through the tubular hand grip 1, between the rollers 15 therein.

The spring 14, urging the free ends of the legs or rods 7 toward the wall 3, will urge the rollers 15 downward between the converging side walls 2, as best shown in FIG. 4, clamping the wire 1% between the rollers 15. It will be seen that any pull upon the tubular hand grip 1, in the direction of the arrow shown in FIG. 4, will tend to more tightly clamp the wire 18 between the rollers 15.

In order to release the end of the wire from the clamp, it is only necessary to pull the closed end 9 of the U-rod 8 toward the wall 4 of the tubular hand grip 1, compressing the spring 14 and moving the rollers 15 upward, as viewed in FIG. 4, so that they may ride upon the upwardly diverging side walls 2 and away from the wire 18, permitting the end of the wire to be easily withdrawn.

From the above it will be evident that a simple, eificient and easily operated device is provided in the form of a hand grip or handle for clamping the end portion of a wire or the like. It will also be: seen that as the pull upon the wire is increased the wire will be more tightly clamped.

In the foregoing description certain terms have been used for brevity, clearness and understanding, but no unnecessary limitations are to be implied therefrom beyond the requirements of the prior art, because such words are used for descriptive purposes herein and are intended to be broadly construed.

Moreover, the embodiments of the improved construction illustrated and described herein are by way of example, and the scope of the present invention is not limited to the exact details of construction.

Having now described the invention or discovery, the construction, the operation, and use of preferred embodimerits thereof, and the advantageous new and useful results obtained thereby; the new and useful construction, and reasonable mechanical equivalents thereof obvious to those skilled in the art, are set forth in the appended claims.
