UNTTEQE STATES GEORGE H. WILSON, OF COLEMAN, ALBERTA, CANADA.

HOG FINGERS.

Application filed March 11, 1921. Serial No. 451,615.

T 0 all whom it may concern.

Be it known that I, Gnonen H. VVILSON, a citizen of the Dominion of Canada. residing at Coleman, in the county of Macleod and Province of Alberta, Canada, have invented certain new and useful Improvements in Hog Pincers, of which the following is a specification.

The present invention relates to pincers, adapted for the attachment of rings to the snouts of swine as a preventive means against rooting.

The principal object of the invention is to provide an instrument of the character described, which will simultaneously insert a plurality of rings within the snout of the swine.

A further object is to provide a device which is of simple construction and economical to manufacture.

-With these and other objects in view. the invention consists in, the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.

Fig. 1 is an enlarged perspective view of the device.

Fig. 2 is a longitudinal section of the same, and

Fig. 3 is-a fragment'al perspective view, illustrating the application of the rings to the pincers.

Referring to the drawings, like nl'nncrals designate like parts in the various drawings.

The numeral 5 designates the pincers com prising two lever handles 6 and 7 having integral jaws 8 and 9, which are connected by a pivot pin 10. The lever handles 6 and 7 are outwardly bowed at 11 and 12 and have their ends inwardly directed as at 13 and 14:. The aws 8 and 9 are in the form of arcuate-shaped claws the inner surfaces of,

which are formed with semi-arcuate grooves 15 and 16. The wire members 17 have their ends spaced apart and are adapted for location within the registering grooves 15 and 16 of the jaws 8 and 9, when the latter are opened widely, as illustrated in Fig; 4.

The jaws 8 and 9 of the pincers are normally held in open position by means of the blade springs 18 and 19, which latter are secured together at their inner ends by a.

are grasped by the handof the operator Y and resultantly the jaws 8 and 9 are opened wide. The wire members 17 are placed within the grooves 15 and16 of the jaws, with their ends spaced apart and the tool is moved, so as to locate the snout between the spaced ends of the wire members 17. Pressure is then exerted upon the handlesfi and 7 and the ends of the wire members 17 will be forced together and will penetrate the snout in the form of rings, as clearly illustrated in Fig. 1.

It is of course obvious that the wire inemf bers may be attached singly, or in units of two or three, and as I find that an active hog wears out a ring in a relatively short time, I have provided a tool for simultaneously attaching several wire members to the sngit. i

From the foregoing, it is thought that the construction of my invention will beclearly understood, and therefore, a more extended explanation has been omitted.

Having thus described the invention, what I claim as new, is:

Hog pincers comprising lever handles pivotally united and having jaws, said handles adjacent their pivot being provided with grooves, springs secured to said handles, a pin connecting said springs near their inner ends, and studs carried by said pin and seated in said grooves.

In. testimony whereof I atfix my signature in the )resence of two witnesses.

GEORGE HERBERT WILSON.

ALBERT HENRY JOHNSTON, ALFRED HAROLD JOHNSTON.
