ORE-DISCHARGE FOR JIG-TANKS.
Application filed August 6, 1908.
To all whom it may concern:
Be it known that we, CHARLES W. WHIT- 11AM and THOMAS S. BALD\VIN, citizens of the United States, residing at Elk Grove and Benton township, in the county of Lafayette and State of \Visconsin, have invented certain new and useful Improvements in Ore- Discharges for Jig-Tanks, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to improvements in ore discharges for jigs.
The object of the invention is to provide a simple and practical discharge which will draw the ore from the center of the ore cell in a much more effective manner than the ordinary side discharges.
WVith the above and other objects in view,
the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of an ore concentrating jig equipped with the improved center discharges for the ore cells or compartments; Fig. 2 is an enlarged vertical transverse section taken on the plane indicated by the line 2-2 in Fig. 1; Fig. 3 is an enlarged detail sectional view through the discharge; Fig. 1 is a cross section taken on the plane indicated by the line 4 1 in Fig. 3; and Fig. 5 is a perspective View showing the several parts of the discharge separated from each other.
In the drawings 1 denotes the body of the fig tank which is provided with a downwardly and forwardly inclined false bottom 2 and which has a central longitudinal partition 3 in each of the several similar sections of the tank to separate each of said sections into a plunger compartment 4 and an ore compartment or cell 5, said compartments 4, 5 being in communication beneath the partition 3, as clearly shown in Fig.
6 denotes a plunger which reciprocates in the compartment 4 and is connected by a rod 7 to a cam or eccentric 8 upon a longitudinal counter-shaft 9.
10 denotes an ore pan which receives the ore from suitable taps or outlets 11 provided in the lower portion of the front wall of the tank for the purpose of drawing off the fine ore which settles upon the bottom 2.
12 denotes the concentrating screen or Specification of Letters Patent.

Serial No. 447,262.
sieve arranged horizontally in the upper portion of the ore cell or compartment 5 and supported upon an open frame 13. While said screen may be of any suitable form and construction it is usually made of perforated sheet metal.
The above described parts are old and well known and form no part of the invention.
14 denotes the improved center discharge for the coarse ore which settles upon the top of the screen 12. Said discharge is preferably constructed of two pipe sections 15, 16 united by an elbow 17, which latter is arranged below the screen 12. The pipe 14 extends downwardly and forwardly and through the front wall of the jig tank, its projecting outer end being provided with a suitably controlling valve 18 arranged immediately above the ore pan 10. The pipe is disposed vertically and projects through the center of the screen 12, its upper end being open and disposed slightly above the upper surface of said screen serves as an outlet for the ore. In order to provide a proper jigging action of the water at said outlet and to maintain the same motion and level of the water at this point as that over other portions of the screen, an annular series of openings 19 is formed in the pipe 15 just below the screen 12. The inlet of water through said openings 19 is adapted to be controlled by means of an adjusting sleeve 20 which is arranged upon the screw threaded exterior 21 of the pipe 15 and is formed with an annular series of openings 22 which are similar to the openings 19 and which are adapted to be moved into and out of register with the latter in order to control the passage of water through the same. The provision of the adjusting sleeve 20 permits said inlet openings 19 to be varied in size according to the size of the perforations in the screen 12 so that the level and motion of the water over the discharge will be the same as at other points 011 the screen. WVhile the discharge may be secured to the screen in any suitable manner it is preferably retained in position by means of a nut 23 which is screwed upon the projecting upper extremity of the pipe 15 and is adapted to clamp the screen 12 between it and the sleeve 20. In the lower pipe 16 are formed openings 24 to permit of the inlet of water into said pipe for the purpose of preventing the latter from clogging.
In operation, when the plunger 6 is reciprocated water in the ore cell 5 is forced up through the screen 12 so that the ore upon said screen is agitated and Washed. The fine ore will pass through the screen and settle upon the front of the inclined bottom 2 and the coarse ore which cannot pass through the screen will find its way into the center discharge 14 through the openings 19 on the upper portion of pipe 15 of said discharge. By providing the adjusting sleeve 20 so that the size of the openings 19 may be made to correspond with the size of the perforations in the screen 12, the Water at said discharge will have the same motion and level as that over the other portions of the screen. It has been found in practice that this improved center discharge is much more effective and will draw off more ore than the usual side discharges.
Having thus described the invention what is claimed is:
1, In a jig, the combination with a screen, of an ore discharge pipe having an open upper end projecting vertically through the center of the screen, said pipe having a screw threaded portion and being formed with inlet openings, located beneath the screen, and
an adjusting sleeve arranged upon the screw threaded portion of said pipe and formed with openings adapted to be moved into and :1
out of register with the openings in the pipe when the sleeve is adjusted thereon.
2. In a jig, the combination with a screen, of an ore discharge pipe having an open upper end projecting vertically through the center of the screen, said pipe being formed with inlet openings located beneath the screen, and means for varying the size of said inlet openings forthe purpose set forth.
3. In a jig, the combination with a screen, of an ore discharge pipe having an open up per end projecting vertically through the cen ter of the screen, said pipe being formed with inlet openings located beneath the screen, for the purpose specified.
In testimony whereof we hereunto aflix our signatures in the presence of two witnesses.
