UNITED STATES PATENT OEEToE.
EDWARD W. WESTON, OF PROVIDENCE, PENNSYLVANIA.
CORRUGATED IRON REVOLVI'NG COAL-SCREEN.
Specification forming part of Letters Patent No. 71,099, dated November 19, 1867.
To all whom it may concern:
Be it known that I, EDWARD W. WESTON,
of Providence, in the county of Luzerne and State of Pennsylvania, have invented a new and Improved Corrugated Iron Revolving Coal-Screen 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings. t'ormin g part of this specification, in which- Figure 1. represents a side view of my improved revolving corrugated iron coal-screen. Fig. 2 is a crosslsection taken in the line a; x, Fig. 1.
Similar letters of reference indicate corresponding parts.
This invention relates to an improvement in the construction of screens for separating broken anthracite coa-l and assorting it in dit' ferent sizes, and other similar purposes; and consists in making a long cylindrical iron screen with its sides corrugated longitudinally, instead of having a plain surface, as in the ordinary mode of construction.
A represents a long cylindrical screen, made of sheet or cast iron plates, and divided into sections perforated with holes or openings of diiierent sizes, in the usual way, for separating and assorting the broken coals in difterent sizes, to be deposited in bins or apartment-s 1 2 3 as the coal falls from the screen.
The sides ofthe screen have lcorrugations 1 2 3 4, Ste., made in them lengthwise, as shown in the drawings, and the superior advantage v of this mode of construction consists in the constant agitation and shifting produced among the coals when the screen rotates, by which the separation and assortment of the dit't'erent sizes are rendered more rapid and effectual.
With the ordinary plain or smooth sided cylinder, the coals lie inert and slide in a mass upon the bottom of the screen when it rotates without that active movement and quick interchange ot' their relative positions which is necessary to present the pieces of all sizes rapidly and successively to the openings for their passage through the screen. But with my improved corrugated screen the body of coals is constantly lifted from the bottom and carried up the sides of the screen by their resting in the depressions of the corrugations until they reach apoint where they tumble over, and thus produce an active shifting of the coals in their relative positions, byxwhich means they are brought rapidly opposite the openings and screened effectively.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is f l Constructing a revolving iron coalscree11 with corrugated sides, substantially in the manner and for the purpose herein described.A
The above specification ot my invention signed by me this 28th day of June, 1867.
E. W. WESTON.
