ORVILLE EWING, OF DECATUR, ILLINOIS.-
TENDQN-CUTTING IMPLEMENT.
SPECIFICATION forming part of Letters Patent No. 252,306, dated January 17, 1882.
Application filed October 21, 1881.
To all whom it may concern:
Be it known that I, ORVILLE EWING, a resident of Decatur, in the county of Macon and State of Illinois,have invented a new and useful Instrument for Cutting Tendons in Hogs and otherAnimals, of which the following is a specification, having refezeuce to the accompanying drawings.
My invention relates to an instrument principally designed for cutting the tendons of the adductor muscles of the snout in hogs to pre vent rooting, the object being to make an incision exposing the tendon,topick the tendon up, and to cut a piece out of it at one operation and with one tool.
My invention consists in the combinationand adaptation of the various parts to each other, as hereinafter described, and set forth in the claim. i v
The accompanying drawings illustrate my invention.
Figure 1 is a side elevation. Fig. 2 is a front end view.
A pair of pivoted jaws terminating in handies held apart by a spring. 8, forms the foundation of my implement. ()ne of thesejaws, a, is longer than the other, and is tapered to a smooth rounding point, and is curved upward and forward. The straight portionof the jaw a is lined with soft metal, to serve as a cuttingbloek for the knives hereinafter described. Secured to the opposite jaw, 12, is a pair of knives, c c, placed lengthwise ,of thejaw, and secured one to each side of the jaw, leaving a space between them. A third knife, 6, is placed in a slot extending centrallyalong the back or outside of the jaw a.' Said knife 0 is pivoted in the jaw at i, and has its cutting-edge turned out ward and conforming in shape to the outline (No model.)
of the jaw, but is so placed that when in its 40 normal position the edge of the knife is a little below the surface. A stud, n, is secured to the rear end of the knife 0, and a spiral spring, 0, is' coiled about said stud, abutting against the button on the stud and against the jaw,.and
thus serves to keep the cuttin g-edge of the knife withdrawnbelow the outside of the jaw.
The operation of my device is as follows:
The implement is held in the right hand and the stud n is depressed by the thumb or fore- 5o finger thus exposing the knife 6 and bringing it into the position shown in dotted lines, Fig. 1. With the knife ean incision is now made longitudinally along the snout on each side of tor muscles, which elevate the tip of the-snout. On releasing the studn the knife e is sheathed in thejaw a ,'and the point of thejaw a is now inserted under the tendon, and a turn of the the center, exposing the tendons of the adduc- 5 5 hand picks up the tendon and brings it under the knives c c. A griping pressure on the handles brings the jaws a and b together and cuts out a short piece of the tendon, leaving the ends so far apart that they will never reunite.
The animal, having lost control of the tip of
