OFFICE WIRE WRENCH Edward G. Schwyn, Bryan, Ohio Application July 26, 1944, Serial No. 546,676

4 Claims.

This invention relates to a wire wrench or a wrench-like device which is adapted for twisting two wires together or the terminal end of a wire around a straight-a-Way portion thereof such as one looped around a post.

One object of the invention is to provide a wire wrench which may be made in a single piece and in the form of a simple casting or the like requiring a minimum of machining operations.

Another object is to provide a wire wrench which is inexpensive to manufacture and which may therefore be sold at a relatively small cost.

Still another object is to provide a wire wrench which may be used to twist wires together without marring the surface of the wires, and especially galvanized wires exposed to atmospheric conditions and which are marred by the serrations of a pair of pliers which is the usual tool used for twisting wires together.

A further object is to provide a wire wrench having an opening therein through which one wire may be threaded and the end of the wire bent so as to hold the wire while a cam-like slot of the wire wrench coacts with another wire whereupon the wrench may be rotated for swingin the first wire toward the second one and keep them tight, and then upon further rotation the first wire is wrapped around the second one with the wrappings spaced as desired.

With these and other objects in View, my invention consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, wherein:

Figure 1 is a face view of a wire Wrench embodying my invention.

Figure 2 is an edge view of my wire wrench.

Figure 3 is a plain view of a post with a wire therearound and my wrench in use, the first step of the wrapping operation being illustrated.

Figures 4, 5 and 6 are similar views showing further progressive steps in the wrapping operation.

Figure 7 isa sectional view on the line 'I-'l of Figure 6.

Figure 8 is a view similar to Figure 6 but with the wrench omitted and the wire wrapping shown complete, and

Figure 9 is a face view of a, modified form of my wire wrench, particularly adapted for heavier wire.

On the accompanying drawing I have used the reference character B to indicate the body memher of my wire wrench. The body B has a handle portion l0 and a pair of curved finger-like portions I2 and Id. The portions I2 and I4 form a slot I '5. The outer end of the slot I 6 terminates in a hook-like member I8 while the inner end of the slot terminates at substantially the center of the tool. Surrounding the inner terminal end of the slot I6 is a cone shaped projection 20 adjacent which is an inclined boss 22. The boss 22 has an opening 24 formed therethrough, the inclination of which is approximately the same as the inclination of the surface of the cone.

In Figure 9 I illustrate a modified form of my invention which is similar in most respects to the form shown in Figure 1 and therefore bears the same reference numerals. Slot I6 is somewhat wider, the hole 24 is somewhat larger and the finger I4 and handle II] are somewhat longer, thus adapting the wrench of Figure 9 for heavier wire.

Practical operation In the operation of my wire wrench, taking for example a straightaway or main wire 26 around a post 28 and the terminal end of the wire or wrapping wire being shown at 30, the wire 30 is threaded through the hole 24 in the direction shown in Figure 3 and bent as at 32 to retain the wire wrench on the wire. The straightaway wire 26 may be tightened with a wire stretcher, or by hand by merely moving the wire wrench in the direction of the'arrow a, and the open end of the slot I 6 and. the hook I8 engaged with the straightaway wire I6. By now lifting up on the handle III, the curvature of the slot I6 effects a camming action of the wire wrench upwardly in Figure 3 to the position of Figure 4 wherein the wrench has been tipped about 45 degrees. This causes the wire 26 to move relatively inward as indicated by the arrow 1) in Figure 1 to the position shown by dotted lines at the inner end of the slot. This will cross the wires 26 and 30 as shown in Figure 5 and further rotation will start the wire 30 wrapping around the wire 26 as shown in Figure 6.

Continued rotation of the wire wrench will wrap the wrapping wire 30 several times around the main wire 26 as shown in Figure 8 and towards the end of the wrapping operation, the portion 32 of the wire may be straightened out to finally complete the wrapping. The coils of the wrapping may b either close as shown in Figure 8 or open as desired depending upon the users wishes.

As the hole 24 is smooth and likewise the surface of the cone 20 is smooth, there will be no damaging of the surface of the Wire except possibly the terminal end 32 which is immaterial.

showing the full size for a wrench which will take wires up to about A" in diameter, and Figure 9 being on a smaller scale and adapted for wrapping wires up to in diameter or thereabouts. At the same time my wire wrench is very simple to make and requires but a minimum of machining operations after it is cast.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope without sacrificing any of the advantages thereof.

I claim as my invention:

l. A wire wrench comprising a substantially flat body having intermediate its ends a cone shaped projection from the plane of the body, a slot having its outer open end at one end of said body member and extending inwardly to said cone shaped projection and having its inner end terminating substantially at the center thereof, said slot being curved and adapted to receive a main wire in said outer open end of said slot and to guide said wire to the inner end of the slot with a, camming action, due to its curvature when the wrench is rotated around said wire, said body member having an angularly directed hole therein to receive a wrapping wire portion of said main wire after it extends around a post or the like, reception of said wrapping wire portion being adjacent said cone shaped projection and on the side thereof opposite said slot, and said angular holebeing surrounded by an inclined boss extending part way up the side of said cone shaped projection, the direction of said hole being substantially parallel to the surface of the cone.

2. A wire wrench comprising a body having a cone shaped projection from one face thereof, a slot having its outer open end at one end of said body member and extending inwardly to said cone shaped projection, said slot being adapted to receive a main wire in said outer open end of said 4 slot and having a curved side of substantial length adapted to guide said wire to the inner end of the slot with acamming action when the wrench is rotated around said main wire, and said body member having an angularly directed hole therein to receive a wrapping wire portion of said main wire after it extends around a post or the like, reception of said wrapping wire portion being adjacent said cone shaped projection and on the side thereof opposite said slot, the angularity of said hole permitting said wrapping wir portion to be bent to an acut angle after passage therethrough whereby said camming action can be had and some tightening of the wire will occur during such action.

3. In a wire wrench, a fiat body' having a slot extending inwardly from one side of said body,

said slot being adapted to receive a main wire and to guide it to the inner end of the slot with a camming action when the wrench is rotated, said slot having an elongated concave side terminating in a hook to engage said main wire for the purpose of starting said camming action, said concave side of said slot effecting completion of the camming action as the wrench is rotated, said body member having an angular directed hole therein to receive a wrapping wire portion of said main wire which can then be provided with an acute bend to retain said wrapping portion therein until such rotation is well started.

4. In a Wire wrench, a substantially fiat handle member having a camming slot from one end thereof, one side of said slot being elongated and concave, a cone shaped projection from one face of said handle member and surrounding the inner terminal end of said slot, and a hole through said handle member and opposite said slot, said hole extending at an angle inclined in the general direction of the surface of said cone shaped projection.
