IMPROVEMENT IN ANIMAL-SHEARS.

Specification forming part of Letters Patent No. 155,295, dated September 22, 1874; application tiled July 6, 1874.

To all whom it may concern:

Be it known that I, CHARLES COURTOIS, Jr., of Paris, in the Republic of France, have invented an Improved Instrument for Shearing and Clipping Animals, of which the following is a specification:

My invention consists in a shearing and clipping instrument, composed of several blades, which are so constructed and pivoted together that they may be spread open for sharpening, or taken apart for grinding like the blades of ordinary scissors, as hereinafter particularly described.

In the acccompanying drawing, Figure 1 is a side view of one form of my invention, with the blades in position for use. Fig. 2 is an edge view of the same, partly in section. Fig. 3 is a side view, representing the blades spread open for sharpening.

The blades are all connected to a common pivot at their lower ends. The pivot P has attached to it, near one end, a circular plate, H, outside of which is an angular head, to which is fitted a coiled spring, J, the free end of which bears against a stud, j, on one of the outer blades D, the other outer blade D having an angular hole fitting the angular end of the pivot. The central blade B and intermediate blades C C are arranged onA the cylindrical portion of the pivot between the outer blades. On the inner side of one of the outer blades D is a stud, i", which engages with a slot, l", in the adjoining intermediate blade C. On the blade C is a stud, t2, which enga-ges with a slot, l2, in the central blade B. On the blade B is a stud, i3, which engages with a slot, Z3, in the other intermediate blade C 3 and on the blade C is a stud, t4, which engages with a slot, Z4, in the other outer blade D. By means of these studs and slots the blades are connected with each other, and their motion is limited. The outer blades D D have rounded handles 7c attached to their outer edges to facilitate the handling of the instrument.

When pressure is applied to the handles the blades are closed, and when the handles are released the spring J forces the blades apart to the position shown in Fig. l, in which position the instrument is ready for use.

When it is desired to separate the blades, for the purpose of sharpening them, they are sprung outward, so as to disengage the studs from the slots, when the blades may be readily spread, as shown in Fig. 3.

The spring for operating the blades need not necessarily be a coiled spring, as it Will be readily seen that a bow-spring will accomplish the same purpose.

I elaiin- The shearing` and clipping instrument, composed ofthe three or more blades B C D, connected by a pivot, P, and pins X i2 3, and slots ZX l2 Z3, and a spring, J, substantially as herein specified.

CH. COURTOIS, Jr.
