WVILLIAM W. HUNTLEY, OF SILVER CREEK, NEW YORK, ASSIGNOR, BY MESNE ASSIGNMENTS, TO HUNTLEY, CRANSON & HAMMOND, OESAME PLACE.

DEVICE FOR OPERATING THE SHAKING-SHOES OF GRAlN-SCOURERS, 8L0.

SPECIFIOATION forming part of Letters Patent No. 436,581, dated September 16,1890.

Application filed June 4:, 1888- Serial No. 275,935- (No model.) I

- To all whom it may concern.-

from the main driving-shaft.

The object of my invention is to provide a simple connection whereby the shaking-shoe is operated directly from the main shaft.

The invention consists of the improvements which will be hereinafter fully set forth, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation of a grain-scourer provided with my improved shoe-actuating device.

Fig. 2 is a vertical longitudinal section of a portion of the vibrating shoe, showing the plate to which the end of the connecting-strap is secured. Fig. 3 is a top plan view of said plate. Fig. 4 is an enlarged side elevation of the actuating device. Fig. 5 is a cross-section of the oscillating quadrant and its supporting-bracket. Fig. 6 is a cross-section of the eccentric and a portion of the connecting-strap.

Like letters of reference refer to like parts in the several figures.

A represents the stationary frameof a grainscourer.

B is the casing inclosing the revolving scouring drum or cylinder, and G is the windtrunk.

cl is the horizontal driving-shaft arranged lengthwise of the machine and upon which the scouring drum is mounted. The driving shaft cl is journaled in bearings arranged in the end frames ofthe machine.

E represents the shaking shoe arranged above the casing B and supported upon flexible arms or bars a, secured with their lower ends to the frame A. The shaking-shoe E contains the sieves 0r screens and vibrates in a plane parallel with the driving-shaft d, or in the longitudinal direction thereof.

F represents an eccentric mounted on the driving-shaft (Z, and F is the eccentric strap or yoke provided on its upper side with a lug or car f.

G represents an oscillating quadrant pivoted to a bifurcated bracket g, secured to the upper rear cross-piece of the frame A above the shaft 01 and swinging in the same plane as the shaking-shoe.

H is a metallic connecting-strap secured at its lower end to the lug f of the eccentricyoke F and at its upper end to a metallic plate I, secured to the bottom of the shakingshoe by screws 1'. The plate I is provided on its inner side with a projecting rim or lug t", which fits in a circular recess formed in the bottom of the shaking-shoe and assists in rigidly securing the plate to the shoe. The connecting-strap H passes over the curved face of the quadrant G and is secured thereto by rivets or otherwise, so as to move therewith. The eccentric F imparts a reciprocating motion to the connecting-strap H, and the latter in turn transmits a similar movement to the shaking'screen in the longitudinal direction of the driving-shaft (l. The lower portion of the connecting-strap H adjacent to the lug f is preferably bent or twisted in line with said lug, as shown, so that the strap may yield laterally and follow the movements of the eccentricF without straining or bending the strap.

The connecting-strap consists of a single strip of metal having sufficient flexibility to permit its being bent around the quadrant H, and is free from any joint, which are liable to become worn.

This construction forms a simple and cheap connecting device for transmitting motion to the shaking-screen directly from the drivingshaft. It does away with the usual countershaft, pulleys, and belt, and reciprocates the shoe with a less violent motion than the cocentric andj connecting rod heretofore employed.

My improved device is shown as applied to the shaking-shoe of a grain-scourer; but it is obvious that it may be used in other similar machines in which the shaking-shoe is arranged above the driving-shaft.

I claim as my invention- The combination, with the stationary supporting-frame and the horizontal drivingshaft jonrnaled therein, of a shaking-shoe supported upon the main frame above the 5 driving-shaft, an eccentric F, mounted on the driving-shaft and having a yoke provided With a lug f, an oscillating quadrant G, pivoted to the main frame above the drivingshaft, and a metallic connecting-strap H, run- IO ning over said quadrant and secured with its upper end to the shaking-shoe and having its lower end twisted in line with the lug f of the eccentric and secured to the same, substan: tially as set forth.

WVitness my hand this 29th day of May, 1888. I5
