JACOB D. ZEISLOFT, OF FOSTER, PENNSYLVANIA.

COAL-JIG.

SPECIFICATION forming part of Letters Patent No. 437,743, dated October 7, 1890.

Application filed January '7, 1889. Seal No. 295,701. (No model.)

To all whom t may concern:

Be it known that I, JACOB D. ZEISLOFT, of Foster township, county of Luzerne, in the State of Pennsylvania, a citizen of the United States, have invented certain new and useful Improvements in Coal-Jigs, of which the following is a specification.

My invention relates to coal jigs or washers employed for separating slate from coal at the mines by washing with a strong upward' and intermittent current of water, the water being actuated by a movable plunger which forces the water up through the coal and slate and separates them, holding the coal in suspension, while the -slate and other extraneous matters fall down through the perforations or openings in the bottom.

The objects of my invention are to prevent the great waste of water and eect a better separation by improving the construction of the apparatus; and to these ends I close the end of the tank, formerly left open, to prevent the free running out of the water with the coal and retain a large portion of it in the tank to be used again. I slope the bottom of the washing-chamber from the center downward to the sides, so as to throw the greatest quantity of the coal and slate adjacent to the sides in order that the coal may be readily thrown over into the elevation boxes, andI provide the washing-chamberwith an additional floor depressed below the main licor to catch the heavy lumps held back by the fenders.

My invention consists in the several novel features of construction and operation hereinafter more fully described, and set forth in the claims annexed.

The invention is constructed as follows, reference being had to the accompanying drawings, in which- Figure 1 is a plan view. Fig. 2 is a vertical longitudinal section. Fig. 3 is a vertical section on the line 3 3, Figs. 1 and 2. Fig. 4 is a section on the line 4 4, Figs. 1 and 2. Fig. 5 is a transverse vertical section through the chamber 11. Fig. 6 is a like view through chamber 13.

A is the tank, provided with a vertical transverse wall 1, ext-ending nearly to the bottom and forming one side of the pistonchamber, and being parallel to the ends 2 and at right angles to the sides 3 and 4.

5 is a frame-work supported at one end upon the wall 1, and at the other upon the partition 6. The frame-work carries the bottom 7, inclined each way from the center downward to the sides and provided with insterstices or large perforations S, and 9 is a secondary double-inclined bottom at the end of the bottom 7, lying in planes below those of the sections of the main bottom.

B is a plunger-piston operated vertically and forcing water from the chamber 10 through under the wall 1 and upward through the bottom 7.

A partition 6 rises vertically from the bottom 9, or it may rise from the bottom of the tank, and is provided with a fender 11, proj ectin g inwardly, substantially as shown, and creating a chamber 13 between this partition and the front 12 of the tank, and this chamber is also provided with a doubly-inclined and perforated bottom 7 n, having perforations 8. Gates 14 are mounted on each side at the lower ends of the bottom 9, through which the slate therein is discharged. The chamber 13 is also provided with gates 15, controlling openings at the bottom and on each side through which the coal mixed with a small quantity of slate is discharged with accompanying water into the elevator box or leg 1G, from which it is lifted by the buckets a of the rotating elevator O, and from the fact that the buckets are placed diagonally to the periphery of the elevator and consist merely of fiat pieces, secured at one edge, as soon as a bucket rises above the top of the side of the elevatorbox the coal and slate are discharged into the inclined chutes 17, whence it is discharged through the wicket-gates 1S, which are opened and closed by the handle, as shown in Fig. 2.

It will be observed that by the use of the partition 6, which operates as a dam, less water is permitted to enter the chamber 13 than if no such partition were there, and that the fender operates to retard the flow of water and to catch and hold back many pieces of heavy slate which would otherwise be carried over into the chamber 13. It will also be observed that by the use of the iiat diagonal buckets I am only compelled to raise the coal IOO and slate to just above the edges of the tank, thereby saving a great amount of power as compared with the cup-buckets. It will also be seen that Jthe doubly-inclined bottoms in the main receptacle and of the slate-recep- 'tacle'and of the coal-receptacle throw or cause the coal or slate to slide downto the sides ,and to the gates in they coal and slate chamers.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the Washing-chamber having the perforated bottom, the means for forcing Water up through said bottom, the settling-chamber having the double-inclined perforated bottom located at a lower plane than the bottom of the Washing-chamber,

lgates opening from the lowest portion of the settling-chamber, the rearvvardlyextending
