UNITED STATES PATENT OFFICE.' I
A. WVASHBURN, OF MEDINA, AND T. BRINTNALL, OF YORK, OHIO.
IMPROVEMENT IN MACHINES FOR SHEARING SHEEP.
Specification forming part of Letters Patent No. 59,103, dated October 23, 1866.
To all whom, it may concern:
Be it known that we, ALvAH WASHBURN, of Medina, and THOMAS BRINTNALL, of York, in the county of Medina and State of Ohio, have invented a new and useful Improvement in Sheep-Shears; and we do herebyr declare the following to be a full, clear,and eXact description of the same, sufficient to enable one slilled in the art to which the invention appertains to make' use of it, reference being had to theA accompanying drawings, which forni a part of this specification, and in which- Figure 1 is a perspective view. Fig. 2 isa detached view ot' the shears and flexible attachment thereof to the tumbling-shaft.
The shears are provided with a shield over the cutters, to prevent the wool being cut more than once, and are attached by means of flexible connections and tumbling-rods to a counterbalance-arm, which is pivoted upon-a standard, on which is placed the drivin g-wheel which gives the vibrating motion to the knife.
In the drawings, A is a base, which may be a removable board, a bench, or table, as may be convenient. From it rises a standard, B, which ai'ords support for the axis C, which is common to the drivin gwhee1 D and the counterbalance-arm E.
To the driving-wheel axis is attached the crank-handle F, and the motion of the driving-wheelis communicated to the smaller wheel G on the upper end of the arm E by means of a band or cord, H, which runs in grooves in the peripheries of the respective wheels.
The arm E is capable of motion in a vertical plane at the option of the shearer. The wheel being continuously turned by an assistant, the shearer draws down -the end of the arm, so as to bringthe shears to the convenient position for application on the animal.
. To the axis of the Wheel G is attached a exible coupling, I, which, by means of the tumbling-rod J and flexible coupling K,is connected to the axis L of the crank M, by which the cutter-bar N is vibrated.
The cutter-bar N is pivoted in the case O, and vibrates between the guards P and shield R, Fig. 2.
The shears, as has been said, have a guardplate, P, whose rear extension forms a bearing for the crank M, which operates the cut- The forward end of the cutter-bar has teeth n, whose vibration forward and backward over the edges of the guards severs the wo'ol which comes between them.
The wool when cut lies upon the shield, and is restrained from falling again into the jaws and being again cut and shortening the staple.
. The weight ot' the shears is counterbalanced by the weight S, which is adjustable at the portion cot'the arm E, bein g setat therequired position by the set-screw e.
The shield R is adjustable toward and from the points ot' the guards, and is attached by screws m to the guard-plate P, clips partially inclesing the boss on tbe rear of the guardplate, and also its straight portion, as seen ii Fig. 2.
To facilitate the withdrawal of the crank M-'its lower bearing is placed in a plate, 19, which is unfastened by removing the screws Having described our invention, what we claim as new, and desire to secure by Letters Patent, is
l. The swinging arin E, with a counterbal ance-weight, substantially as described.
2. The shaft or tumbling-rod J with liexible connections I K, operating substantiall y as described.
3. The adjustable shield R, covering the scribed.
