ORE-CONCENTRATQR.
SPECIFICATION forming part of Letters Patent No. 794,555, dated July 11, 1905.
Application filed March 29, 1904. Serial No. 200,615.
To all whom/ it may concern:
Be it known that we, HANNIBAL SCovELL,
HARLIE B. SoovnLL, LESLIE E. SoovELL, and WILsIE E. SoovnLL, citizens of the United centrated; and the principal object is to simplify and cheapen the cost of construction of such devices and to render more efficient the operation of grading and concentrating the ore.
The invention consists, essentially, of the novel construction and arrangement of the several parts and will be hereinafter fully described, and briefly stated in the claims.
In the drawings, Figure 1 is a side elevation of our improved device; Fig. 2, a top plan view; Fig. 3, an end view showing the fluid-tank, partly broken away; and Figs. 4, 5, and 6, diagrammatic views showing the operative position of the cams and the relative movements of the screen.
Referring to the several views, the numeral 1 indicates a suitable tank or box for holding the water or other fluid for washing the ore. The tank is properly supported in any suitable manner, preferably by legs 2, and is provided at or near the bottom thereof with a suitable discharge-gate 3.
Journaled in suitable bearings4, secured on the upper edges of the respective sides of the tank, are two shafts 5 and 6, and movably suspended from the shafts is a screen 7.
The screen is composed of two sides 8 8, having preferably rounded or curved ends 9 and slightly upwardly inclined ends 10, and
a perforated bottom 11, preferably of woven wire of any desired mesh. The bottom is secured to the sides and firmly held in place by strips 12, which are fastened to said sides by .ment will be imparted to the screen.
between each set of hangers are two rails 16 and 17, spaced apart to receive therebetween cams 18 18, from which the screen is suspended. These cams are mounted on the shafts 5 and 6 and serve -to impart vertical reciprocatory motion to said screen. Mounted on the shaft 6 is a cam or eccentric 19, and secured to the side rails 16 of the screenframe is a cross-rod 20. The cross-rod is connected with the cam 19 by means of a pitman 21, and when power is applied to the shaft 6 a longitudinal reciprocatory move- The motion of the screen may be varied according to the character of work required by adjusting the cams 18, which are adj ustably mounted on the shaft 6 in any well-known manner.
Each shaft is provided with a sprocketwheel 22, over which runs a sprocket-chain 23, and the shaft 6 is provided with a. bandpulley 24, which may be driven from any suitable source of power to drive the shaft 6, and thereby shaft 5.
The device is provided with a suitable hopper 25, in which the ore is fed to the screen, and a wasteway-opening 26 is provided in the rear end of the tank to permit the free longitudinal reciprocation of the screen and the overflow of the waste.
The operation of the device is as follows: Power being applied to the shaft 6 and to the shaft 5 by means of the sprocket-and-chain connection, a vertical reciprocatory motion will v'be imparted to the screen by means of the cams 18 and a longitudinal reciprocatory motion thereto by means of the cam 19 and pitman 21, the combined motions causing the screen to describe in the course of each revolution the form indicated by the letter a, as shown in Fig. 4. By changing the relative position of the cams, as shown in Figs. 5 and 6, the form of motion indicated by and c, respectively, will be described. For all practical results the adjustment of the cams shown in Fig. 6 is preferred. As thus adjusted, the
longitudinal reciprocatory movement will be slight, but its downward vertical movement will be full on the rst half-revolution. The effect of this movement under proper speed will be to force the fluid up through the meshes in the screen-bottom and cause the prepared ore or other -substance to become more or less suspended, the lighter matter, which is usually the waste or refuse, responding first, leaving' the heavier or more valuable matter nearest the screen-bottom to be drawn through the meshes on the upward movement of the screen.
The. waste or refuse matter will be discharged through the overflow-opening, which is the same width as the screen and about two inches above the screen, the iiuid being maini tained ata level.
Having thus described our invention, what we claim, and desire to secure. by Letters Patent, is-
1. In a device of the character described, the combination with a fluid-holding tank, shafts mounted in suitable bearings on said tank, and a set of cams secured on each of said shafts, one cam near each end of each of said shafts, of a screen suspended in said tank, the forward end of said screen having a sharp upward curve, and the tail portionjhereof being slightly upwardly inclined to permit an easy discharge of the waste matter from said screen, a suitable hanger secured to each side of said screen and supported on the cams on the shafts, a cam secured on one of said shafts', and a pitman, one end pivoted to the hangers and the other end provided with a strap adapted to embrace said cam, whereby,when motion is imparted to the shaft, the screen will be given a compound vertical and horizontal movement.
2. In a device of the character described, the combination with a Huid-holding tank, a main shaft and an auxiliary shaft mounted in suitable bearings on said tank, a cam secured near the end of each shaft, and means foroperating said auxiliary shaft from the main shaft, of a screen suspended inv said tank, the forward end of said screen havinga sharp upward curve, and the tail portion thereof being slightly upwardly inclined to permit an easy discharge of the waste matter fromsaid screen, upright pieces secured to each sid'e of said screen and connected by horizontal parallel bars, the upper of said parallel bars being adapted to rest upon the cams near the ends of said shafts, a cam on the main shaft, and a pitman connected with said cam and the upright pieces, whereby, when motion is imparted to the main shaft, the screen will be given an elliptical movement.
3. In a device of the character described, the combination with a' fluid-holding tank, a main shaft and an auxiliary shaft mounted in suitable bearings on said tank, cams adjustably secured on said shafts, one cam being secured near each end of each shaft, and means for operating said auxiliary shaft from the main shaft, of a screen suspended in said tank, the forward end of said screen having a sharp upward curve, and the tail portio'n being slightly upwardly inclined to permit an easy discharge of the waste matter from' said screen, a suitable hanger secured to each side of ksaid screen and supported on the cams on the shafts, a cam-secured on the main shaft intermediate the end cams, and a pitman, one end connected with the hangers and the opposite end with said cam, whereby, when motion is imparted to said shaft, an elliptical movement will be imparted to the screen'.
In testimony whereof we aflx our signatures in the presence of two witnesses.
