WIRE-BINDING PLIERS.

Application filed January 25, 19a'7. Serial n easse.

bending pliers,

present invention pertains to wire and contemplates the prov1- sion of pliers which while simpleand lIlBX- pensive in construction and susceptible of ready operation are possessed of the practical advantages hereinafter ascribed to the same.

The lnvention consists of the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification:

Figure 1 is a side elevation illustrating a pair of pliers constituting the preferred embodiment of my invention.

Figure 2 is an inverted plan view of the male member of the pliers.

Figure 3 is a top plan View of the female member of the pliers.

Figure at is a transverse section taken through the jaw of the plane indicated by the Figure 5 is through the jaw female member in the line 47- 1 of Figure 3. a transverse section taken of the male member in the the line 5-5 of Figure 2.

Similar numerals of reference designates corresponding parts in drawings. pliers are preferably all the views of the The several parts of my novel formed of steel, and

the plier members having portions 1 and 2 arranged side by side, ed together by a pintle handles 4 and 5, respectively,

and pivotally connect- 3 and merged into the said handles being preferably shaped as best shown in Figure 1. The portion 1 is comprised in what I designate the male. member of the pliers, and it will be understood by the comparison of Figuresl and 2 that the said portion 1 is provided adjacent to its forward end with a lateral mandrel 6, and carries at its forward end a jaw 7. shaped as illustrated in Figures 1,

The said jaw 7 is 2, and

5i. e., is generally increased in depth from its forward end to its heel end 8, is provided on its under side'with the longitudinally inclined face 9 tapered in width from the forward end of the jaw to end of the jaw,

a point 10 at the heel and is also provided with inclined sides 11 which are increased in height as they recede from the forward end of the jaw and approach the The portion heel end thereof. i 2 of the female member of the pliers is merged at its forward end into a laterally disposed channel portion 12, and the said channel portion 12 is provided at its forward side-with the female jaw 13,

In h

upper side of the said jaw 13'is provided a depression 14 which is increased in depth from theforward end of the jaw 13 to the forward side of the lateral projection 12, and is of angular form in cross section as indicated by 15 in Figure 4.

It will be appreciated from the foregoing that the angularity of the depression 14 in cross-section is increased as the said depression recedes from the forward end of the jaw 13, and that the upper jaw 7 is shaped to fit the depression in the lower jaw, and consequently when a straight wire is laid between the jaws and the handles 4 and 5 are moved toward each other, the wire will be bent to an angle determined by the distance the wire is located from the forward end of the jaw.

It will also be appreciated from the foregoing that by the cooperation of the mandrel 6 wvith the channeled projection 12, small wire loops may be expeditiously and easily formed, the mandrel 6 being arranged to enter the channel or depression in the projection 12 when the jaws are brought together, and in this connection it Will be understood that the depression Or channel in the projection 12 is of semi-circular form in cross section, and that the first manipulation of the jaws will bring about the bending of the wire into a half loop, and

of the loop.

Manifestly in the manner described, a loop for a binding post may be expeditiously and easily formed.

The construction herein described in detail constitutes the preferred embodiment of my invention. I do not desire, however, to be understood as limiting myself to the specific construction and relative arrangement of the parts as disclosed, my invention being defined by my appended claim within the scope of which modifications may be made without departure from my invention.

Having thus described the invention, what I claim is A pair of wire bending pliers comprising side by side portions pivotally connected to.-

5 jaws having a longitudinal depression in creased in depth from the forward end. of the jaw to the heel end of the jflW,3Ild the other jaw having a longitudinal projection adapted to enter said depression, end one of the side by side portions being also pro- 1 vided with a lateral projection of channel cross section, and the other side-by-side portion equipped with a lateral mandrel 211-' ranged to eooperate with the said channeled projection.

In testimony whereof I aflix my signature.

ERNEST BERTON VARNEY.
