TO ALL WHOM IT vMAY CONCERN:

Be :'t known that we, GEORGE HARSIN and C. 'LS-ANDERS, of Kirkville, in the county of Wapello, and State of Iowa, have invented a. new and useful Improvement in Machines for Shearing Sl1eep;'and 'we do hereby declare that tbc following is a full, clear, and exact description of the same, reference being had t the annexed drawings, makingvpart of this specification, in which Figure 1 is a side elevation.

Figurc 2.is an elevation of the shears. v

Figure 3 a longitudinal section of' thcvpoint of thestock and shears; and.'

Figure '4 asimilar section ofthe butt of thc stock.

The same letters in all the figures are used to indicate identical parts.

In the annexed drawings, A, A1, and A? are the posts, to which the shearing-mechanism is attached by cords B and B.

C is the cutter, and D a table, upon which the sheep to besheared is placed, the sheep being rested against l the knee of the operator, whose foot should be placed on the table, whilewith his right hand he directs the cutter, ivith the left rolling backthe eece.

The. cutter is constructed as follows:

C1 is achambered wooden or metallic stock, constructed to receive the shearing-mechanism, which is driven by the band B, which enters the stockl through a glass thimble placed in the end'tliereof to prevent friction. This band passes arounda pulley, G, pivoted to the stock, and having an eccentric wrist-pin, G', which is received in a. slot in the end of the arm H, attached to an oscillating cutter, I, constructed, as represented, vi'ith knives shaped as shown, and sharpened upon the edges. This oscillating cutter is pivoteclto the stationary cutter K, constructed with the same-kind of projections and cutting-edges, the two sets of cutters acting upon the same principle as the knives of n. harvester, forming, with the oscillation of the blade I, shears to cut the fleece as the point is carried along thebody of the sheep.

The set-screw I" is intended to keep the blades in clos-e contact.

'Ihe cutter is attached to the cord B,fastened to the eye-holt C3. .'The oscillating knife is driven by the band or cord B, which .passes over the driving-pulley L, which is turned by hand or other power. This band is carried over the pulley M, and thenl through the thmble C2, and around the pulley Ggwithin the stock, and then back through the thimble and over thc pulley N to the driving-wheel. The cord B attached te the stock is carried under the pulley O, thence up over the pulley P, and has a. weight, E, attached to the loose end thereof.V As the cutter is moved, this cord maintains the tension of the belt, on which is placed a. tensiontveight, F, fastened to a running sheave,vu'hich, when the belt is slacked, maintains it tantly on the pulleys,

.so that the cutter may be moved as fur as may be necessary withfiut affecting the movement of the knife I.

What we claim as .our invention, and desire to secure by Letters Patent, is v l'. In combination with thercutt'er C, the belt B and cord B', running over pulleys, and' kept taut by weights, arranged to operate substantially as and for the purpose set forth.

2. The combination, in a sheep-shearing machine, of a stationary-blade, K, und oscillating blade I, constructed and arranged, in relation to one another, substantially as set' forth.

3. The arrangement of the pulley G, havinga wrist-pin, G, slotted arm H, oscillating cutter I, and stay' tionary knife K, within the hollor case Gf, substantiallyv as and for the purpose set forth.

In testimony whereof, we have signed our names toz'tzhis specification in the presence of two subscribing witnesses.

l GEORGE I'IARSIN,

y C. T. SANDERS.
