IMPROVEMENT IN SHEEP-SHEARS.

Specification forming part of Letters Patent No. 187,266, dated February 13, 1877; application tiled August 3, 1876.

To all lwhom Iit may concern:

Be it known that I, WILLIAM GEORGE, of Modesto, Stanislaus county, State of California, have invented an Improved Sheep-Shears, of which the following is a specification:

My invention relates to an improvement in sheep-shears; and consists in the peculiar construction of the blades,ha\'ing formed between them a tongue-andgroove chamber or recess and, further, in the novel arrangement and combination therewith or' a spring fo'r actuating the shears, all as more fully hereinafter described and detinitely claimed.

Figure l of the accompanying drawings is a vlew of my improved shears, showing` their form and the shape and arrangement of the spring. Fig.2is a view ofthe two parts separated from each other. Fig. 3 is a longitudinal section ot' the same, with the blades closed.

A is the spring, with two arms and a central hole, a, that lits upon a pivot in the blade B. The ends ot' this spring, when the two halves B B are brought together, come in contact with and press against the pins b b, one on theinner face oi'.the blade B and the other on that of the blade B'. The shank ofthe blade B' at the part c is beveied or finished with an inclined curved surface, that lits into and within the curved groove d, formed in the shank of the blade B, so that when the twoparts are placed together vand the rivetm inserted 1n position the blades are held by these parts c d in close and proper cutting relation with each other, and all tendency to separate or spread is thus prevented, the edge c turning and working within the recess d.

As thus constructed and arranged, the blades of my improved shears are thrown apart when the handles C C are released, as the spring A between the shanks B B presses the one arm against the pin b of the blade B and the other against the pin b of the blade B. The rivet x holds the parts together, and the edgesc dof the shanks prevent the blades from spreading. The ends of the handles are relieved from the concussion ofthe two parts striking against each other by the rubber bucer or spring c.

Having thus fully described my invention, what l claim as new, and desire to secure by Letters Patent, is-

1. In a pair of sheep-shears, the combination, with the curved bevel edge c on the shank ot' one of the blades, of the curved slot or recess d on the shank of the other blade, operating substantially in the manner set forth.

2. In a pair ot' sheep-shears, the combination, with the blades- B B', having the curved slot or recess d and the curved bevel edge c, ofthe chambered spring a, working on pins b b', all constructed, arranged, and operating substantially as described and shown, for the purpose specitied.

In testimony that I claim the foregoing I* have hereunto set my hand and seal this 15th day ot' May, 187 6.
