UNITED STATES PATENT ()FFTQ.
NELSON MOWERY, OF WILKES-BARBIE, PENNSYLVANIA.
COAL-SEPABATOR.
To all whom it may concern:
Be it known that I, NELSON MownnY, a citizen of the United States, residing in WVilkes-Barre, Pennsylvania, have invented certain Improvements in Goal-Separators, of which the following is a specification.
My invention relates to that class of coal separators either stationary or vibratory, in which the coal, mixed with slate, is permitted to slide down an inclined trough or chute having therein longitudinal slots presenting lateral openings of such size that they will permit of the lateral escape of the relatively fiat pieces of slate while preventing such escape of the pieces of coal.
The object of my invention has been to simplify the construction of such separators and render them more efiicient in operation than previous separators of this type. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawing, in which Figure 1 is a top or plan view of a coal separator or separator section constructed in accordance with my invention; Fig. 2 is a longitudinal section of the same on the line aa, Fig. 1; Fig. 3 is a transverse section on the line b?), Fig. l, and Fig. 4: is a transverse section on the line 0-c, Fig. 1. Figs. 2, 3 and t are on a larger scale than Fig. 1.
The separator consists of a plate 1 of steel or other sheet metal having at each side an upturned flange 2 which may be secured to the fixed framework of the separator, or, where the separator is composed of a number of adjoining sections, may be secured to the corresponding flange of an adjoining section, in order to rigidly secure the said sections one to another. This plate is slitted so as to form a number of parallel fingers or blades 3, the slits extending from the lower edge of the plate to within any desired distance from the upper edge of the same, and the upper or root portion of each blade being then bent downwardly from its center line in one direction and upwardly from said center line in the opposite direction, as shown in Fig. 3, so as to provide, between the adjoining blades of the plate, lateral passages 4, preferably of the same width from the bent portion of the blade to the lower end of the same, as shown in Fig. 2. The blade thus prepared is mounted either upon a transverse beam at the head of the Specification of Letters Patent.

Serial No. 493,835.
plate, as shown by dotted lines in Fig. 2, or upon longitudinal bars of a supporting frame, as shown by dotted lines in Fig. 3, so as to occupy any desired angle of inclination, and the coal, mixed with the slate, is permitted to slide down the surface of the plate, the openings at being of such size as to permit of the lateral escape of the relatively flat pieces of slate while preventing such escape of the pieces of coal, which are of a larger size than the fiat-wise dimensions of the pieces of slate, the lateral inclination of each of the blades 3 serving to direct the pieces of slate toward the openings at the lower sides of said blades.
The lower ends of the blades 3 are free from any rigid support consequently said blades retain their normal resiliency and are free to yield at their lower ends.
It will be evident that a separator in accordance with my invention can be constructed at a minimum of expense, and owing to the resiliency of the blades 3 such separator is more efficient in operation than one having blades rigidly supported at both ends, since the yielding of the blades 3 at and near their delivery ends will prevent clogging of the openings 4: with wedgeshaped pieces of slate and will permit of the escape of pieces of slate which are too large to pass through an opening whose width is rigidly maintained from end to end.
I claim 1. A coal separator consisting of a plate of-sheet metal slitted to form adjoining resilient blades free from connection with one another at their delivery ends, and bent at their root ends so as to provide lateral openings between them.
2. A coal separator consisting of a plate of sheet metal slitted to form adjoining resilient blades free from connection with one another at their delivery ends, and bent at their root ends so as to provide lateral openings between them, and means for mounting said plate with the delivery ends of the blades unsupported and free to yield.
3. A coal separator consisting of a plate of sheet metal slitted to form adjoining resilient blades free from connection with one another at their delivery ends, and bent at their root ends so as to form between adj oining blades lateral openings of substantially uniform width from the bent portions of the blades to the delivery ends of the same.
4:. A coal separator consisting of a plate livery ends of the blades unsupported and 1C of sheet metal slitted to form adjoining re free to yield. silient blades free from connection with one In testimony whereof, have signed my another at their delivery ends, and bent at name to this specification, 1n the presence of their root ends so as to form between adj ointWo subscribing Witnesses.
