Application filed February 11, 1905. Serial No. 245,250.
view through my improved coal-washing apparatus indicated by the line I I of Fig. 2. Fig. 2 is a plan view of the apparatus. Fig. 3 is a vertical cross-sectional view on the line III III of Fig. 1. Fig. A is an enlarged vertical detail view of the jig on the line IV IV of Fig. 2. Fig. 5 is a partial similar view showing the discharge-gates raised. Fig. 6 is a vertical sectional detail view of one of the valves of the jig, showing it opened.
My invention refers to improvements in coal or ore washing machinery or apparatus, and relates to a construction whereby a constant circulation and supply of water is furnished to the jig-tank and various other parts of the apparatus, to an improved arrangement of the various tanks and bins, elevators, conveyers, &c., and also to an improved construction of reciprocating jig, whereby the burden of coal is supported in such a manner as to permit a free circulation of water there through, so as to separate it by buoyancy or flotation from the slate, sulfur, and other impurities, together with other features of improvement, which shall be more fully hereinafter set forth.
Referring now to the drawings illustrating the invention, .2 represents a dry coal-bin, to which coal may be delivered by any suitable means, as an elevator 3, said bin being arranged at a sufficient elevation to deliver the coal to the jig by gravity. Adjacent to the coal-bin 2 is located the jig-tank 1, beyond which is the settling-tank 5, arranged to receive the washed coal carried over by the water through an intervening channel 6, preferably inclined downwardly toward the settlingtank 5, as shown and as commonly arranged in similar apparatus. Between the jig-tank 1 and settling-tank 5 I preferably locate an intervening overflow-tank 7, into which the water flows from the settling-tank through an intervening opening 8, while a similar opening 9 communicates from the overflow-tank to the jig-tank 4. At the inner side of this opening 9 is a flap-valve 10, arranged to open inwardly to permit an inflow of water to the jig-tank upon upward motion of the jig, but to close against said opening, preventing the return of the water upon downward travel of the jig, thereby retaining the water in the jig-tank and causing it to pass upwardly through the bottom of the jig as it descends.
11 is the jig, consisting of a rectangular framework of any suitable construction, preferably provided with a surrounding bearingplate 12 at its upper portion, arranged to make a snug practically water-tight lit within a cor-- responding surrounding bearing 13, located in the interiorof the upper portion of the jigtank, as shown in Fig. 1. Extending across the lower portion of the jig is an inclined primary floor or bottom 14, of perforated metal,woven wire,or other suitable construction having sufficient strength to sustain the body of coal contained in the jig, provided with a series of perforations or openings adapted to permit a free copious upward circulation of the water as the jig descends. Below said primary bottom 14 is a secondary bottom 15, preferably made of sheet metal and also inclined downwardly toward one side or end of the jig, as is bottom 14. The secondary bottom 15 is provided with a plurality of inwardly-opening valves 16 of any suitable construction adapted to open upon downward movement of the jig to allow an inflow of water and to become seated as the jig rises, so as to provide for an upwardly-traveling circulation of water through the body of coal and also to-create a suction through the valve-controlled opening 9 to produce an inflowing current to the jig-tank. At the lower side or end of the primary bottom 1 1 and secondary bottom 15 are located openings 17 and 18, respectively, which openings are closed by gates or valves 19 20, separately connected by suitable connecting-rods 21 with independent operating-levers 22 23, mounted at the upper edge of the jig and preferably provided with notched segments 24: and suitable locking-latches, whereby the gates 19 and 20 may be set at varying heights or positively held entirely open or closed, as desired. These gates and the facility of their manipulation are important and useful features of the jig, permitting the accumulations of the slate, sulfur, &c., to be drawn off from time to time from the primarybottom 14. and also providing for the discharge of the accumulations of sludge and fine matter settling upon the floor 15.
The jig is reciprocated by means of connecting-rods or pitmen 25, mounted upon eccentrics or cams 26 and shafts 27 geared together, as shown in Fig. 2, and actuated by ,an y suitable driving mechanism, as a powershaft 28. By this means the jig is vertically reciprocated, and as the coal isdischarged downwardly into it from the bin 2 the operation of the jig will separate the lighter coal from the heavier impurities, the coal passing over into the settling-tank by the buoyant action of the upwardly-traveling water, the heavier impurities settling to the bottom 14: of the jig and from thence downwardly through the jig-tank into its lower portion, from whence such waste matter is removed by a screw conveyer 29 into an adjacent slate-bin 30, an elevator 31 being provided to empty said slate-bin. If preferred, the lower floor of the jig-tank may be merely inclined toward the slate-bin 30, so as to deliver thereinto by gravity.
' The washed coal is removed from the settlingtank 5 by an elevator 32 to any suitable point of discharge, and as thus arranged provision is made for continuous operation, the various tanks and reciprocating jig providing a regurgitating system for the water.
The operation will be readily understood from the foregoing description, and the apparatus is well adapted to thoroughly wash the coal and separate it from its impurities, being capable of practically automatic operation with very little attention and being capable of a large output of washed coal.
Various changes and modifications may be made in the design, proportions, or various details of the construction by the skilled mechanic without departing from my invention; but all such changes are to be considered as within the scope of the following claims.
