ALBERT SENEFF, OF LA RAMIE CITY, "WYOMING TERRITORY, ASSIGNOR TO HIMSELF AND FRANCIS MULHER-N, OF SAME PLACE.

ORE DRIER AND $EPARATOR.

SPECIFICATION forming part of Letters Patent No. 294,157, dated- February 26, 1884.

Application filed June 30, 1883. (No model.) a

1"; all whom it may concern.-

Be it known that I, ALBERT SENEFF, of Laramie City, in the county of Albany and Territory of \Vyoming, have invented a new and Improved Ore Drier and Separator, of which the following is a full, clear, and exact description.

My invention consists of improved apparatus for slowly passing the ore down a heated shaft or flue'of a furnace by devious courses on pans or disks that have a slight shaking motion for distributing, agitating, and urging the ore forward, from which the ore is discharged upon along sloping and graduated screen, to be graded and discharged into different hoppers, from which each grade is passed separately through a conductor and falls past or through ablast of air from a blow-pipe supplied by a bellows, by which the earth and other matters are blown away, while the ore falls into receptacles provided for the different grades, all as hereinafter fully described, and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improved drier and separator. Fig. 2 is a longitudinal sectional elevation. Fig. 3 is a sectional plan view of thedrier on line 00 00, Fig. 2. Fig. 4 is an end elevation, and Fig. 5 is a transverse sectional elevation online 3 y of Fig. l.

A represents a furnace of cylindrical form, on the top of which is a cylindrical case or tube, B, resting on a ring, F, and forming a heat-flue, through which the products of combustion escape upward from the furnace. \Vithin this case B, I have arranged a series of sheet-iron hoppers, a, with intermediate conical disks, H, on a vertical shaft, G, the hoppers discharging at the center onto the disks, and the disks discharging from their outer edges into the hoppers, for causing the. ores to traverse to and from the center and circumference of the heat-fines, for producing the best effects of the heat within the smallest space for drying purposes. The disks are attached to the shaft, and the hoppers are connected to the disks for support by the rods or The shaft Ghas a step in a cross-bar,

bars L.

b, at the top of the furnace, and it passes through a cross-bar, c, of a ring, K, at the top of case B, for its upper support. Ahopper, I, with a sloping screen, d, for a bottom, is located on the top of shaft G by a metal socket having a set-screw, J to secure the hopper in any desired radial direction. Below the lowest hopper a the shaft G passes through a spout, E, into which said hopper discharges the ore to be conducted from the drier into the separator, said spout being inclosed in ajacket, c, which isemployed to lessen the loss of heat through the spout E, and-particularly to inclose a space wider than said spout E, in which the spout vibrates to impart a slight forward and backward motion to the hoppers and disks of the drier, to prevent the ores from lodging on them and to cause them to feed properly. The shaft has a collar, f, in spout E, that is connected to the bottom plate of said spout E by the plate 9 and lugs or bars 71, projecting from said collar and attached to said plate 9, the spout E extending out of the drier and intothe separator, and through a notch in the upper edge of a sliding bar, 0, suitably arranged in cleats attached to the end of separator-frame G, for being shifted forward and backward by connecting-rod N and the cranked disk M to vibrate said spout, and thus cause it to shake the hopper and disks. The screen din hopper I is to separate any coarse matters too large to pass through the drier and separator and discharge them onto the ground. In practice it will be detachably connected to hopper I, in order that interchangeable screens of different mesh may be applied as may be required. The spout E discharges onto the long sloping grading-screen Q, of five different sections and discharging into five different hoppers, \V. This screen is arranged over a series of knifeedged scrapers, V, arranged lengthwise of it, and placed about as far apart as the screen shifts in shaking, and with their upper edges touching the screen, to force up any lumps or other matters lodging inthe screen, to prevent it from being choked and clogged. This screen rests on the friction-rollers z, fitted on studpivots attached to the frame, and is connected to the vibrating lever B by the rod j to be operated, said lever B being worked by the studpin in the side of cone-pulley S, acting on the shoulders Z of the yoke m of said lever, embracing the main driving-shaftn of the machine. The lever B is pivoted on the countershaft 1) for its fulcrum. From the series of hoppers V the different grades of ore fall into a corresponding series of shaking-spouts, X, to be discharged at the ends of said shakers, so as to fall into the receptacles D, the falling streams passing a series of blowrpipes, 0 from which they are treated to airblasts Which strike them directly under the bottoms of the shakers and free them of all light dirt and other matters of less specific gravity than the ores by the same being carried beyond the re ceptacles D, While the ores fall into them. The air for this purpose is supplied to the trunk by a pair of bellows, Y, located above the screen Q, and operated by the sliding bars a, rock-lever A, pitman, cranked disk (1, belt 15, and the pulley u on the drivingshaft it. These bellows discharge the air into a pressure-reg ulai'or, Y, for steadying the blast, from which the air passes by the conductors B to the trunk 10. From the trunk 20 the air passes intoa chamber, b, for each blast-tube through an orifice, a, regulated by a valve, E, and a thumb-screw, d, to vary the force of the blast, the thumb-screws extending out through the case of the trunk 10, Where they can be manipulated by the attendant at will. The shakers are attached to a bar, 0, arranged for Jul sliding in a way, T, and having a lever, F", connected to it, said lever being pivoted at h fora fulcrum, and being worked by the grooved cam G and a stud-pin of said lever extending into the groove of said cam.

This cam is fitted loosely on the main shaft 72, and is driven by counter-shaft p, cone-pulleys t" and j, and belt k, the cone-pulleys being employed to vary the speed of the shakers as may be required. The cone-pulleys S, by which the screen Q is operated, are also driven by shaft 1), belt Z, and cone-pulley m, to vary its speed also. This counter-shaft p is driven from the main shaft n by a belt, a, and pulleys, for the purpose of driving the shakers and screen as above.

The drier is designed to stand at one end of the separator, and is connected to it by hooks D, for steadying one by the other.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the hopper I, screen (1, hoppers a, conical disks I-I, shaft G, heatilue B, and vibrating spout E, as and for the purpose described.

2. The combination of the spout E, jacket 0, sliding bar 0, shaft G, the hopper, and the disks, as and for the purpose set forth.

3. The combination, in an ore-separator, of the sloping graded and shaking screen Q, series of hoppers XV, shakers X, blow-pipes c, and receptacles D substantially as described.

4. The bellows Y, regulator Y, conductors B and the air-trunk w, in combination with the blow-pipes c, shaking-spouts X, and the receptacles D", substantially as described.

ALBERT SENEFF.
