Description
` I INTTED STATES PATENT OFFICE.
GEORGE E. MCVEY, OF SPRATTS, VIRGINIA, ASSIGNOR TO JOHN A. GROSE- CLOSE AND EDWARD P. SCOTT, OF MARION, VIRGINIA.
WH EAT-S EPARATO R.
SPECIFICATION forming part of Letters Patent No. 671,223, dated April 2, 1 901.
Application filed July 16l 1900. Serial No. 23,751. (No model.)
To al?, 'whom t mfc/y concern:
eitknown that I,GEORGE E.MCVEY,a citizen of the United States, residing at Spratts, in the county of Smyth and State of Virginia, have invented certain new and useful Im provements in Wheat-Separatore; and I do hereby7 declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to ro which it appertains to make and use the same. The subject of this invention is a device for separating grain and other materials; and
it consists in a novel mechanism for governing the inclination ofthe separating-sieve and for supporting and vibrating the same.
In the accompanying drawings, forming a part of this specification, Figure 1 is a perspective view of the device. Fig. 2 is a central vertical longitudinal section thereof. Fig. 3 is a vertical transverse section. Fig. 4 is a top or plan view.
Referring to the drawings, 1 1 indicate base pieces or feet which respectively carry end uprights 2 and 3, which serve to support the vibratory separating-screen and the devices for vibrating the same. The said uprights are braced at one side by a longitudinal bar 4, preferably arranged horizontally and near the bottom, and at the other side by a similar longitudinal bar 5, which is preferably inclined upwardly (for purposes of better bracing) from near the bottom of the upright-3 to a point somewhat above the lower portion of the upright 2, as shown. Between the bars 4 and 5 is secured a standard or body-piece 6, which projects under the screen at a point about its middle portion and is preferably inclined upwardly and toward the upright 3 and with relation to the angle of inclination of the screen.
The screen or sieve 7 is in the main of any suitable or adapted construction and is supported in inclined position at its rear or lower end by a rod 8, pivotally connected to the screen at a central point with relation to the width thereof, as at 9, and having at its top end an eye 10, by means of which it is hung from any one of the plurality of pins 11 upon the inner face of the upright 3 and may be adjusted thereon. The rear end ofthe screen is also notched `or recessed, as shown at 12, to form side projections 13 13, and said notched end straddles the upright 3, as shown, so that lateral displacement of the screen is prevented. Thefrontorupper end of thescreen is supported at opposite sides of the upright 3 by rods 14 14, pivotally connected at their lower ends, as at 15, to the end of the screen and pivotally connected at their upper ends,
as at 16, to a transverse top bar 17 upon the 6o front upright 2. The front or upper end of the screen is also notched or recessed, as at 1S, to form side projections 19 19, and said notched end straddles the upright 2 to control the lateral play of the screen. The supporting-rods 14 14 may be connected at their lower pivots 15 to the projections 19 19, as Shown.
The upright 2 and middle standard 6 carry in suitable bearings 2O 21 a rotary shaft 22, 7o having an operating handle or crank 23 at its outer end, while on the inner end thereof, at a point in rear of the standard 6 and under the middle portion of the screen, .is a crank end 24, connected bya pitman 25 withan arm 75 or bail depending from the under side of the screen, by means of which mechanism the screen is vibrated from side to side. The pitman 25 is preferably double for purposes of greater strength and better bracing, as shown, 8o and the arrangement provides for the strong and positive actuation of the screen at its middle portion intermediately between its ends. The hopper 26 is secured to the upper end of the upright 2 and delivers to the up- 85 per end of theV screenin an obvious manner.
In operation it will be understood that by turning the shaft 22 the pitmen 25 cause the screen to swing from side to side, and the inclination of the screen can be readily ad- 9o `justed, as before described, to secure the most IOO 2. In asepaxa'or, a. frame havinguprights, In testimony whereof I aHX my signature a screen swingingly supported at both ends in presence of two witnesses. from said nprghts and having its ends straddling the same, and a rotatable shaft mount- GEO' E MCVEY" 5 ed upon the upright and having a crank and Witnesses:
ptman connection with the screen at a pointl T. V. MCVEY,
intermediately of its ends. M. A. MCVEY.
