INSTRUMENT FOR CASTRATING, DOCKING, AND EARMARKING SHEEP, CATTLE, OR HORSES.

SPECIFICATION forming part of Letters Patent No. 795,205, dated July 18, 1905.

Application filed December 29, 1904. Serial No. 238,800.

To It lull/07w it may concern:

Be it known that 1, JAMES DIGNAN, a subject of His Majesty the King of the United Kingdom of Great Britain and Ireland, and a resident of Hobson street, in the city of Auckland, in the Provincial District of Auckland and Colony of New Zealand, have invented a new and useful Instrument for Cast-rating, Docking, and Earmarking Sheep, Cattle, or Horses, of which the following is a specification.

This instrument is intended for use by farmers, run-holders, stock-holders, and others in all the operations of castration, docking, and earmarking. It is a combination-tool of snips with springs fixed, within the handle ends, having the snips inwardly sharpened and curved, with the outer edge of one of the snips sharpened to form a knife-edge and having the ends of the snips projected at right angles, the inner sides of the projections being suitably corrugated, and with a punch fitted inwardly to one of the handles.

Four figures are shown on the accompanying drawings, of which- Figure 1 is a front view of the instrument opened out, showing the different parts. Fig. 9. is a front view of the instrument closed. Fig. 3 is a side view of the instrument closed, showing the projecting clamps on end of snips at right angles; and Fig. A is a broken perspective view of the ends of the snips and projecting clamps therefrom at right angles, showing the corrugations in one of the clamps.

The snips A and B are upper projections of the handles C and D, and they are inwardly sharpened at A and B to form cutting-blades. The snip or blade A has an inwardly-flat surface and is broader than the inwardly-flat surface of the snip or blade B. It is also difierently shaped and projects beyond the blade B when closed, as is shown in Fig. 2. The inner edges of both blades are curved from about the center of the instrument where pivoted to their inner points, as shown in Fig. 1. The outer edgeE of snip or blade A is sharpened to a knife-edge. The outer points F and G of the snips A and B are turned and projected at right angles thereto for a length of about two inches to form clamps, and the ends M are turned'in to engage one another when closed. The inner sides of the clamps F and G are corrugated so that the corrugations of the one will fit into the grooves between the corrugations of the other when closed. The point H of the snip A is turned outward slightly to facilitate the closing of the one blade onto the other.

The spring J is provided within the handles C and D, which are inwardly arched to suit the formation of the spring shown. The handles C and D are hinged together in scissors form either by rivet or screw. At the end of either of the handles C and D a punch K is inwardly fixed, shaped as shown in Figs. 1 and 2, though this particular form need not be adhered to, as any suitable shape can be adopted. I

In use the outer knife-blade is used to cut the purse or any other substance. It may be more convenient to use it for and with young animals. It may be used in place of the two inwardly-sharpened blades A and B. In operating the clamps F and G are used instead of the teeth of the operator, and the ends M are turned inward to engage one another, so as to prevent the substances between the clamps slipping out from between them. The inner blades A and B on being closed together by the compression of the handles C and D cut the substances placed between them, and so complete the operation for which the instrument is designed and made. The punch K can be used for earmarking purposes by also compressing the handles, when a piece will be snipped out of the ear placed between the punch and the inner side of the opposite handle, which is suitably shaped for the purpose, as shown in Figs. 1 and 2. The curving of the inner blades A and B makes the cutting efiect more perfect and effective. A good etfect may be obtained by giving these inner blades asaw formation, somewhat the same as is done with some bread-knives now in use.

Having fully described my invention, what I desire to claim and secure by Letters Patent is A device of the character described, comprising a pair of handles pivotally connected intermediate their ends and having integrallypro ecting blades said blades having inner their outer ends With inwardly-extending IO i projections, said projections cooperating in use to retain material between the clamp 1 members.

JAMES DIGNAN.
