Patented May 1 1, 1909.
Application filed July 16, 1907. Serial No. 384,088.
To all whom it may concern:
Be it known that I, JOHN T.. DONOVAN, Sr., a citizen of the United States, residing at Lampasas, in the county of Lampasas and State of Texas, have invented new and use ful Im rovements in Ore-Separators, of which t e following-is a specification.
This invention relates to separators or concentrators for separating or extracting gold'from pulverized quartz, sand or gold bearing dirt; and it has particular reference to an improved pneumatic separator for extracting or separating flake and flour gold.
The invention has for its object to provide a machine of the class referred to which shall possess superior advantages in point of simi sists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and par.- ticularly pointed out in the claims.
In the accompanying drawing has been illustrated a simple and preferred form of the invention; and in said drawing the single figure represents a vertical sectional view of an apparatus constructed in accordance with the invention.
The improved apparatus comprises a casing constructed with a wind trunk, which includes a vertical limb 1 adjacent to the front end of the casing, a vertical limb 2 adjacent to the rear end of the casing, and an approximately horizontal portion 3 that extends longitudinall through the casing and connects the 'lim s 1 and 2.
4 represents a suction fan; the casing of which 5is supported adjacentto the rear end of the casing; the eye 6'01 the fan casing being in communication with the lower end of the limb 2 of the wind trunk.
A trough 7 is suitably su ported adjacent to the lower end of the lim 1, which latter is provided near its lower end with an inlet aperture 8 and a shield 9 which constitutes a guide or be per over whichmaterial may be guided tot e inlet aperture 4 from a suitably supported shaking screen 10, which, in turn, receives the material from the hopper 11.
Hingedly supported within thelimb 1 of the wind trunk, near the u per rear end of the latter, is a shield or dhflector 12 the lower end of which has an adjusting rod 13 extending through the front wall of the limb and provided with an adjusting nut 14' ably supported for rotation in the hopper 15' is a cylindrical screen 17; and cleats 18 are disposed to contact with said screen, and to cooperate with the latter to obstruct the wind trunk or passage. An inclined deflector 19 extends from the top of the wind trunk downwardly and rearwardly into the hopper 16; and a horizontally disposed deflector 20 is arranged adjacent to the upper rear edge of said hopper. The hoppers 15 and 16' are provided with outlets designatedrespectively 21 and22.
The crushed or pulverized ore or sand or other material that is to be operated upon is fed over the shaking screen 10 and throu h the aperture 8 intothe lower end of t e limb 1 of the wind trunk, in which suction is set up by means of the fan 4 which is driven in any convenient manner; the shield 12 .being adjusted according to the specific gravity of material that is to be operated upon and other well known conditions. The particles of material, suspended in the a11- current, will presently im inge upon the cylindrical screen 17, whic is suitably rotated, the com arat-ive'lyfine particles passing through t e screen while the coarser particles are separated through the outlet 21 of the hopper 15. Within the hopper 16 another separation takes place,'t e relatively heav fiecte-d by the deflectors 19 and 20 and separated through the outlet 22, while the flour gold, which is in the form of an impalpable powder, will continue on through the limb 2 of the wind trunk and through the fan casing, being finally delivered into a dust collector which is suitably connected with said fan casin and a portion of which is con ventional y indicated at 24.
This improved se arator, as will be seen, is extremely sim e in construction and operation, and it as proven in practice to be thoroughly eflicient for the purposes for which it is provided. By means of this ma chine, the flake and flour gold may be exand coarse particles being de- 5 the bottom of the limb an 'flector projecting forwardly from the upper rear portion of the hopper above the chamber of the latter and parallel with the plane of the limb, a second deflector arranged in rear of the vertical center of the hopper and extending at a downward and forward angle from the top wall of the limb and cooperating with thehorizontal deflector to contract the limb above the upper rear portion of the hopper, and a rotary screen mounted to rotate partially within the hopper and partially within the limb between said deflectors, said screen being arranged to leavea passage between the same and the front wall of the hop er for the entrance of the coarser material w ich cannot pass the screen to said hopper.
2. A separator of the character described comprising a casing having a windtrunk with t e u per ends of said vertical limbs,
the latter eing provided respectively with an inlet and an outlet at their lower ends, the lower end of the front wall of said front limb terminating above the lower end of the rear wall thereof, V-shaped hoppers arranged between the vertical limbs and depending from the base of the horizontal limb, each of said hop ers being provided at its lower reduced en with an outlet eommunieating with the underlying portion of the I casing, a horizontal deflector projecting forwardly from the upper rear portion of each hopper above the rear wall of said hopper and arallelwith the horizontal limb, inclined deflectors arranged in advance of said horizontal deflectors and projecting rearwardly from the ,up er wall of the horizontal limb at a downwarc angle, a screen guarding the upwardly extending duct above the forward hopper, a conical rece )tacle arranged at the base of the vertical in ct limb, a suction device communicating with the outlet of the vertical discharge limb, ore feeding means, and an inclined chute extending from said delivery means to a point between said conical receptacle, and the lower end of the short front wall of the inlet limb and spaced from the latter to provide an intervening feed passage communicating with said limb. In testimony whereof, I affix my signature 1n presence of two witnesses.
