BULL-HOLDING INSTRUMENT.

Specification of Letters Patent.

Patented Nov. 8, 1921.

Application filed December 14, 1920. Serial No. 430,636.

T 0 all whom it may concern:

Be it known that I, ORIN E. HATCH, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented a new and Improved Bull-Holding Instrument, of which the following is a full, clear, and exact description.

This invention relates to improvements in bull holding instruments, an object of the invention being to provide an instrument which is adapted to be positioned in the nostrils of the bull, grip the cartilage between the nostrils and hold the bull during the puncturing of the cartilage for the reception of a ring.

A further objectis to provide an instrument of the character stated which is so shaped and constructed as to form a guide for the passage of a trocar or other sharp instrument to puncture th cartilage.

With these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in'the claims.

In the accompanying drawings- Figure l is a view in elevation showing in full lines the normal closed position of the instrument and in dotted lines the open position of the same.

F 2 is a view in side elevation of Fig. 1.

1, 1. represent the handles of my improved instrument and 2, 2, the jaws which are made integral with the handles and are pivotally connected by means of a rivet 3. The jaws 2, 2, curve outwardly in opposite directions and are spaced apart as shown clearly in Fig. 1, when the instrument is in closed position, suitable shoulders or enlargements 4 being provided on the handles to limit their closing movement so that the free ends of the jaws are properly spaced when the instrument is closed.

It is to be understood, of course, that the free ends of the jaws are suificiently close together when the instrument is closed to form an effectual grip upon the cartilage between the nostrils of the bull, but prevent puncturing or injuring the cartilage.

It will also be noted particularly by reference to Fig. 2 that the 2, 2, not only curve in opposite directions away from each other, but also have a transverse curvature in the same direction, thus permitting the instrument to be located at a proper angle so as to provide clearance and not interfere with the using of a trocar or other sharp instrument to puncture the cartilage.

Furthermore, it will be noted that the free ends of the jaws 2, 2, are provided with recesses 5, 5, said recesses being in alinement when the jaws are in closed position to provide a space and also operate as a guide for the operation of a trocar or other sharp instrument to puncture the cartilage of the animal.

I also preferably provide in one or more of the handles 1 an opening 6 to receive a rope to assist in holding the animal.

In order to provide a full gripping surface and a full guiding surface for a trocar or a sharp instrument, the extreme ends of the jaws 2, 2, are preferably enlarged transversely as indicated in Fig. 2, and by reason of the shape of the jaws and their dispositioI. relative to the handles, the instrument can be conveniently employed to securely hold the head of a bull and operate as a guide for the punching operation.

Various slight changes might be made in the general form and arrangement of the parts described without departing from the invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit ant scope of the appended claims.

I claim:

1. An instrument of the character stated, comprising pivoted jaws, handles opera tively connected to the jaws, means limiting the pivotal movement of the handles wheresaid jaws are spaced apart when in closed position, and said jaws having registering trocar guiding recesses at their free ends in their outer faces, said jaws curved in opposite directions and curved transversely in the same direction.

2. An instrument of the character described, comprising a pair of pivoted jaws, handles fixed to the jaws, said jaws curved in opposite directions and having their free ends spaced apart when the instrument is closed, and said jaws at their ends enlarged transversely and having trocar guiding recesses in alinement in their outer faces.

ORIN E. HATCH.
