JASPER SNELL AND JOHN R. DEIHM, OI! POTTSVILLE, PENNSYLVANIA.
COAL-SCREEN.
Specification of Letters Patent No. 24,155, dated May 24, 1859.
To all whom it may concern:
Be it known that we, JASPER SNELL and J OHN R. DEIHM, of Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented a new and useful Screen for Separating Slate from Coal; and we do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings.
The nature of our invention consists in so constructing a coal screen of metallic plates or'blades, that the coal shall pass over and be discharged at the foot of the screen without passing through it; whileall laminate matter such as slate, shale, &c., shall pass through between the plates or blades of the screen and be deposited under it, thus being separated completely from the coal.
In the accompanying drawings Figure l is an isometrical projection, and Fig. 2, is a cross section of our improved coal screen.
The end A or receiving bed of the screen is elevated to a considerable degree above the foot as in other screens for the purpose of allowing the coal to run down over it with facility. This may be effected by making one pair of legs longer than the other and shown in Fig. l, or by adopting any other common device.
B, B, are two cross bars attached to the under side of, and supporting the frame of the screen; a bar near each end. The upper surface of each of these bars is cut into ratchet like notches, the longer sides of which slope downward, away from the center of the screen, toward its outer edges and serve to support the ends of the plates or blades C, in such a manner that their inner edges shall be higher than their outer edges, and an open space be left between the inner edge of each one and the outer edge of its neighbor for the whole distance between the bars B B. This space need only be so wide as to allow those fiat substances to pass through which it is desirable should be separated from the coal. This construction will be easily understood on referring to the drawing.
A guard ledge D extends along each side of the screen parallel with the blades 0, to prevent the coal from falling off before it reaches the foot.
The operation of this screen is as follows: viz---The coal is thrown on to the higher end A of the screen; it then slips down on to and over the blades C, and being of rough irregular shapes will not pass through the spaces between the edges of the plates C but will continue down to and be discharged at the lower end; while pieces of slate, shale or anything that is flat will be governed by the sideway inclination of the said plates andwill pass between them in the direction indicated by the arrows. The masses of coal will be guided in their descent to the foot of the screen by the upraised inner edges of the plates 0.
Having thus fully described our inven tion, what we claim therein as new and desire to secure by Letters Patent is The arrangement of the plates or blades C in parallel planes with spaces between their edges so as to slope lengthwise of the screen, and cross wise from the center of the screen,
substantially in the manner and for the purpose hereinbefore specified and set forth.
