SHEEP-SHEARING MACHINE.
SPECIFICATION forming part of Letters Patent No. 415,365, dated November 19, 1889.
Application illefl March 27, 1889- Serial No. 304,946. (Model.) l
To all whom 71mg/ concern:
Be it known that l, ROBERT MONDAY, a citizen of the United States, residingat Lainpasas, in the county of Lampasas and State of Texas, have invented a new and useful Improvement in Sheep-Shearing Machines, of which the following is a specification.
My invention relates to an improvement in sheelJ-shearing machines; and it consists in 1o the peculiar' construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.
In the drawings, Figure l is a perspective view ot' a sheel'i-shearing machine embodying my improvements. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a horizontal section. Fig. t is a detail perspective view of the cutter-plates. Fig. is an enlarged front elevation showing one of the teeth of both the upper and lower plates.
The basevplate A, which is rectangular in form, is provided with a rearwardly-extending arm B of suitable length, and has its front edge serrated to form teeth C. The under sides of the teeth are curved upward, as shown, and the upper side of each tooth is hollowed to form an oblique concavity D, the same extending to the right, and cuttinggo, edges or flanges E being formed on the lefthand side of the teeth, as shown. A transverse coneavity F is 'formed in the upper side of the base-plate at a slight distance in rear of the teeth C. The upper plate G is somewhat smaller than the base-plate, is provided with a rearwardly-extending arm H, which has an open slot I at its rear end, and the front edge ot the said plate G is serrated to form cutting-teeth l. The said teeth are provided 4o with oblique concavities L ou their lower sides, which extend toward the left, and the right-hand edges of said teeth are provided with cutting-edges M, which are adapted to move laterally over the cutting-edges E of the teeth O. The plate Gis further provided with a circular opening N, in which operates an eccentric O, the latter having a trunnion I on its lower side, which is journaled in a central Opening R in the baseplate. From the upper side of the eccentric extends aver- 5o tical spindle S, which is journaled in the cover or casing T, the front and sides of which are inclined and converge upward, as shown. The sides of the said cover or casing are provided with verticaldepending flanges U, which bear on opposite sides of the baseplate and are secured thereto by means of A set-screw \V works in an opening in the top of the case or cover in rear ot the spindle 6o S, is provided with a jam-nut X, and has a concavity in its lower end. A tumbling-pin Y has one end seated in said concavity and the opposite end seated in a recess on the plate G. A pair of adjusting-screws Z work in threaded openings in the base-plate, eX- tend up into the grooved portion F thereof, and the points of said screws are adapted to bear under the plate G. A flexible driving shaft A, composed of alternate sections of 7o coiled springs B and sleeves C', has one end attached to the spindle S, and the opposite extremity attached to a suitable motor. (Not shown.) A pin D projects from the upper side of the arm B of plate A, at the rear end thereof, and enters the slot I in the arm ll of. plate G.
A cylindrical handle E receives the arms of the plates, and is secured to the arm B by a screw F.
The operation of my invention is as follows.: ll'hen the flexible shaft is rotated, the revolution cf the eccentric causes oscillating motion to be imparted to the plate G, and the teeth thereof are caused to describe acircular 8 5 movement, each of said teeth operating on a pair ot' the teeth O. By reason of the teeth C and M being concave on their opposing sides they are out of contact with each other at all points except their cutting-edges or 9o iianges, and thereby the friction is reduced to the minimum and wear is prevented to a corresponding extent. By adjusting the screw XV and the screw Z the plate G may be caused to Work in a plane nearer to or slightly farther from the face of the plate A, and compensation may be made for Wear of the cutting-teeth. The coneavities formed plate G, operating on plate A and having the Yteeth M, with the concaved lower faces and cutting-edges adapted to operate on thecutting-edges of teeth C, substantially as described.
2. In animal-shears, the plates having the teeth hollowed out on their opposed faces to formoblique concavities and provide cuttingedges at one side of the teeth, substantially as described.
3. The combination of the base-plate A, having the bearing R projecting therefrom, the cap secured to the sides of the base-plate and inclosing the operative mechanism, the plate G, the shaft S, having its lower end journaled in the bearing R and its upper end shouldered and journaled in the top ofthe cap, and the eccentric on the shaft S, resting 3o upon the bearing R and held up from the plat-e thereby, substantially as described.
In testimony that I claim the foregoing as my own I have hereto aiiXed my signature in presence of two witnesses.
ROBERT MONDAY. lVitnesses:
J. H. SIGGERS, R. JSMARSHALL.
