SHEARS FOR DEHORNI NG ANIMALS.

SPECIFICATION forming part of Letters Patent No. 441,065, dated November 18, 1890.

Application filed July 30, 1887. Serial No. 245,724. (No model.)

To all whom it may concern.-

Be it known that 1, JAMES D. GREEN, a citizen of the United States, residing at Arcadia, in the county of Crawford and State of Kansas, have invented certain new and useful Improvements in Dehorning-Shears and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a representation of this invention, and is a perspective View, the wooden handles of the shears beingbroken oif. Fig. 2 is a bottom view, partially open, only the metal portion of the handles being shown. Fig. 3 is a top view closed. Fig. 4 is a vertical section, the handles being broken off atthe ends.

The invention is a device for dehorning young cattle or calves, the object being to amputate the horn as quickly, as readily, and with as little pain as possible; and it consists in the construction of the blades and their combination with the handles in such manner that the blades can be passed downward from above on a horn to be cut, with their cutting-edges downward, as hereinafter described, and embraced in the appended claims.

Referring to the drawings by letter, A A designate the respective blades of the dehorning device or shears, similar in shape, but the blade A slightly smaller than the blade A, so that the former may have its ends inserted between those of the latter, and be pivoted thereto at a near their corners on both sides. The said blades are formed at their central curved portions B B on semicircles, and have their edges Z) I) beveled from without inwardly, as shown in Fig. 4. The blades, between their central curved portions and their ends, extend straight and parallel on each side toward each other, as at O, the ends of the blade A overlapping those of the blade A at their pivoted points, so that when the blades are turned together the edges cut from a considerable angle on each other before they bind on the horn over which they are passed.

D D are the respective handles to the blades A and A, which handles are made of wood and in practice are about two feetlong. The handles are firmly secured by rivets,

screws, or otherwise to the projections cl d integral with and standing from the central parts of the corresponding edges of their respcctive blades. The handles are at such angles to the blades that When the cutting-edges are together throughout their entire extent the handles are quite or nearly in line with each other, and their ends in opposite directions.

The method of using the tool or shears is as follows: The blades A A are passed downward over the horn to be amputated, the cutting-edges being downward and the handles standing front and rear. The latter are then turned, the cutting-edges binding on the horn when the opening between the same has shortened,till it is about circular. Then by continuing to close the handles the blades are caused to bite into the horn, the central parts shearing through in the direction between the handles, while the side portions of the edge of the blade A shear past those of the blade A, and make a downward and inward cut, causing the end of the stump to be concave. The horn is thus cut off at the level of the ends of the hair, or near that position.

The amputation can be done very quickly and readily, avoiding all pain and danger, and is a great improvement over the use of the saw, the knife, or the heated iron.

Having described my invention, I claim- 1. An implement to dehorn cattle, consisting of two curved shearing-blades pivoted together to embrace the horn, and suitable handles whereby such blades are actuated, substantially asspecified.

2. The herein-described dehorning-shears, composed of the two blades made at their central portions on arcs of circles, and having suitable cuttingedges, one being slightly smaller than the other to permit them to be pivoted together near the corners of their straight parallel end portions, and the handles secured to the respective blades in such manner that they will be quite or nearly aligned when the edges of the blades meet throughout their entire length, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES D. GREEN.
