\VILLIAM IV. ROSENSTEEL, OF PITTSBURG, PENNSYLVANIA.

ORE-WASH ER.

SPECIFICATION forming part of Letters Patent No. 403,488, dated May 14, 1889.

Application filed May 9, 1888. Serial No. 273,347. (No model.)

To all whom it may concern:

Be it known that I, \VILLIAM \V. ROSEN- STEEL, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Coal-fashers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in coal-washers; and it consists of the peculiar construction and arrangement of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of my Fig. 2 is an end elevation of the same, partly in section. Fig. 3 is a perspective view of the chute or trough used for conveying the product of the washer to either of the bins.

Heretofore a common practice in coal-washing has been to place the washer at some distance from and on a level with the bottom of the drying-bins, and by a suitable apparatus, designed for that purpose, convey the product first drained through perforated buckets upward and discharge the same into the open top of the drying-bins,where it remains until it dries. It will be seen that by this method a large percentage of the fine slack or pulverized coal passes through the buckets and is carried away and lost by the water used in washing.

In order to construct a coal-washing apparatus in accordance with my invention, I construct a double bin, consisting of two separate drying-bins, a h, each having a perforated inclined floor, c, sloping toward each other and provided at their lowest sides with openings (1, through which the dried coal may pass into a trough, e, arranged below the inclined floors c, and from there, by means of a conveyer, g, to the desired place.

Centrally located above these two bins to b is a coal-washer, c', of any well-known or desired construction, provided with a pivoted chute or trough, Z, arranged below the discharge-openin gs o of the washert' and adapted to receive the entire product of the same and convey the small coal, dust, and water into one of the drying-bins a, where the same is allowed to remain until the water has escaped through the floor 0. At one end of the bins to b is arranged a means for elevating the coal from the crusher to a chute, p, leading to the washer i. p

In operation the coal is crushed, conveyed upward, and discharged into the washer 'L through the chute p. \Vhen the same is properly washed and the slate, sulphur, &c., separated, the coal is discharged from the openings 0 into the inclined trough Z, which conveys it into one of the bins a, the water and coal-dust being also discharged into the same bin. \Vhen this bin at is filled, the trough Z is revolved about its pivot m and made to discharge the product of the washer into the opposite bin, 1). When one of the bins a is filled with coal, coal-dust, and water, the same -is allowed to stand until the water has filtered through the coal and floor c of the bin 0,, thereby leaving in the same all the dust or pulverized coal.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

In a coal-washer, the combination, with a bin divided longitudinally into compartments, of a horizontal washer, 2, located immediately above said bin, transversely across the same, and having a series of overflow-openings, o, and a horizontally-inclined trough pivoted centrally to the side wall of the Washer at a point immediately below the series of overflow-openin gs 0, said trough being of a length less than the width of the bin, and arranged to receive the entire contents of the washer that escape through the openings 0 thereof, and adapted to direct the same into either compartment of the bin, substantially as and for the purpose described.

In testimony that I claim the foregoing I hereunto affix my signature this 17th day of March, A. D. 1888.

WILLIAM W. ROSENS'IEEL. [L 8.]

In presence of- O. 0. LEE, M. E. HARRISON.
