ORE-CONCENTRATOR. 7
ized quartz and the like, may be fed continuously into the machine, the tailings being carried therefrom in a continuous current while a continuous outflow of values occurs at an outlet provided therefor.
Another object is to provide a separator or concentrator of this type which is-simple in construction, can be operated at slight cost, and which operates to separate gold,
platinum and other precious metals in an inexpensive manner and under condit ons where separation is practically impossible at the present time.
A further object is to provide a machine which, by reason of its light and compact construction can be operated readily by hand, thus rendering it especially adapted for use by prospectors.
With the foregoing and other objects 1n view which will appear as the descriptlon proceeds, the invention resides in the combination and arrangement of parts and 1n the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.
In the accompanying drawings the preferred form of the invention has been shown.v
In said drawings: Figure 1 is a side elevation of the machine, a part being shown in section. Fig. 2 is a front elevation, a portion of the spray pipe being shown in section.
Referring to the figures by characters of reference 1 designates a conical body arranged with an outlet at its apex, there being a pipe 3 or the like extending from this outlet so that values discharged through the outlet may be conducted to any point desired. The body is arranged so that its lowermost portion is inclined downwardly to aslight extent from the apex, as shown in Fig. 1, and rims 4 and 5 are located at the apex and about the open face of the body Specification of Letters Patent.

for' engagement with supporting rollers 6 suitably mounted under the body. The body 1 can be rotated in any manner desired, as
by means of a hand operated or a power driven shaft, neither of which have been 7 shown.
A feed pipe 7 extends over one side' portion of the body and is adapted to direct sand, gravel, quartz or the like into the body. A spray pipe 8 is fitted within the upper portion ofand extends close to the body and is in communication with a water supply, not shown. This pipe 8 is adapted to spray water downwardly upon the upstanding por tion of the interior of the body as will be apparent by referring to Fig. 2.
The body 1 is provided with a suitable linlng, indicated generally at 9. This lining can be of canvas, iron, copper or any other suitable material, according to the values to be concentrated. Where sand and quartz is fed to the machine, canvas is prefthrough the pipe 7 and into the left hand portion of the body 1, the same gravitating onto the body at the left of the center thereof. As the lowermost portion of the body is inclined downwardly away from the outlet 2, the lighter particles constituting the tailings will be washed from the body substantially along the lines indicated by the arrow't while the heavier particles or values will remain in engagement with the inner surface of the body and will travel upwardly with said body as indicated by the arrows 9' until they are brought to position under the spraying pipe 8, whereupon they will be washed downwardly and flow wardly, so as to flow continuously through 110 the outlet 2.
Importance is attached to the fact that the inner surface of the body 1 is smooth and is not provided with riffles and the like as such riflies would tend to hold black sand (iron) indefinitely for the reason that it cannot be washed over riflies. Importance is also attached to the fact that the present devices effects the separation very rapidly for the reason that each particle of value, after a one half revolution of the device, reaches a position perpendicularly above the discharge opening 2 and is washed down and through the same by the Water.
What is claimed is An ore concentrator including a conical body mounted for rotation and having a substantially perpendicular portion leading downwardly to the apex of the body and a \slightly inclined portion leading upwardly to the apex of the body, there being an outlet at said apex, means for rotating the 20 body in one direction about an axis extending along said slightly inclined bottom portion, means for directing values onto the bottom portion of the table between the outlet and the front of the table, and means extending along the periphery of the table at the uppermost portion thereof, for directing water downwardly toward the outlet to direct into the outlet values adhering to the table. i
In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
