BRUSH FOR BRAN-DUSTERS, BOLTERS, SCALPERS, GRAlN-SCOURERS, AND SEPARATO R S.
SPECIFICATION forming part of Letters Patent No. 738,166, dated September 8, 1903.
Application filed February 24, 1902. Serial No. 95,421. (No model.)
ll) (6 whmn it may concern:
Be it known that I, GEORGE R. DAVIDSON, a citizen of the United States, residing at Lenox, in the county of Macomb and State of Michigan, have invented a new and useful Brush for Bran-Dusters, Bolters, Scalpers, Grain-Scourers, and Separators, of which the following is a specification.
My invention relates to improvements in bran-dusters, bolters, scalpers, grain-scourers, and separators; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.
In the accompanying drawings, Figure 1 is a diagrammatic sectional view of a branduster and grain-scourer patented by me in the United States March 26, 1901, No. 670,851, provided with my improved brush. Fig. 2 is a similar View showing my improved revoluble traveling brush applied to the grainscourer, separator, scalper, and bolter described and claimed in Letters Patent of the United States No. 664,836, which were granted to me January 1, 1901. Fig. 3 is a similar view showing my improved traveling brush disposed for operation in a grain-scourer and bran-duster described in my pending appli cation for Letters Patent of the United States filed March 19, 1901, Serial No. 51,928. Fig. 4 is a similar view showing my brush bearing against the under side of a reciprocating screen to keep the meshes of the latter clear and to impart vibratory motion to the screen.
In Fig. 1 of the drawings is shown a screen a, which is stationary and is of cylindrical form, and a brush 1, which is carried by and has its bearings in an arm 2, which arm is pivoted, as at 3, to one of the radial arms I) of a spider c, which rotates in the cylindrical screen and is provided with brushes'd, which rub frictionally against the inner side of the screen. proved brush 1, being carried by the revoluble element 0, travels on the inner-side of the screen a and rotates in contact therewith, and the peripheral portion of the said brush, which is here shown as being made of bristles, but which in practice may be made of felt, plush, rubber, or other suitable material, penetrates the meshes of the screen and keeps the latter clear. It will be further understood that owing to the pivotal connection It will he understood that my imbetween the brush-carrying arm 2 and the arm of the spider or revoluble element the said traveling brush is by centrifugal action maintained in contact with the inner side of the screen and bears against the same with a degree of pressure which depends upon the speed of the revoluble element 0, as will be understood.
In Figs. 2 and 3 of the drawings the traveling brush 1 has its carrying-arm 2 pivotally connected to an endless traveling belt or apron e, and the brush is caused by its own gravity to engage the inner side of and travel on the screen a. A spring may within the scope of myrinvention be employed to keep the traveling brush in engagement with the screen, and I do not limit myself in this particular; As here shown, the traveling brush is of poly onal form and the sides thereof as they contact with the screen shake or vibrate the latter, and hence assist in dislodging particles therefrom, thus adding to the efficiency of the brush in keeping the screen clear.
In the modification shown in Fig. 4: the screen a is a flat reciprocating screen, a pitman being indicated ate to impart motion to the screen. The brush 1 is mounted in fixed bearings, bears against the under side of the screen, penetrates and keeps clear the meshes thereof, and the rotation of the brush occasioned by its contact with the moving screen and the polygonal form of the brush imparts vibratory motion to the screen, hence materially increasing the efficiency of the brush.
Having thus described my invention, I claim- 1. In combination with a screen, of a revoluble polygonal brush mounted for orbital movement and means whereby said brush is held in operative engagement with said screen and rotated by contact therewith.
2. The combination of an inclosing screen, a polygonal brush mounted revolubly in contact with said screen, yieldable supporting means for said brush, and means for propelling said brush over the said screen to be rotated solely by contact therewith. r p
3. The combination with a screen ofa brush, polygonal in the sense of having a plurality of fiat surfaces, said brush being mounted for orbital movement within said screen and 10 revoluble brush having its bearings in said arm and adapted to be maintained centrifu gally in engagement with said screen.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
GEORGE E. DAVIDSON.

ARTHUR H. HUNVICK, WM. R. DAVIDSON.
