ORE-SEPARATOR.'

SPECIFICATION forming part of Letters Patent No. 752,027, dated February 16, 1904.

' Application filed January 28, 1903. Serial No. 140,861. (No model.) I

.To a/ZZ {Uh/0m it may concern:

Be it known that I, HENRY JUDsoN BUE- Rouens, a citizen of the United States, and a resident of Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Ore-Sepvara-tors, of which the following is a full, clear,

vide mechanisms or devices for adjusting ori raising and lowering the cylindrical watertank of the separator relative to the mercury or quicksilver tank, the adjusting means being such that they will occupy but little space, will not be easily injured, and are very positive and satisfactory in operation.

With these and other objects of a similar nature in view my invention consists in the peculiar construction.' combination, and arrangement of parts, as will be hereinafter described in this specification, delineated in the accompanying drawings, and set forth in the appended claims.

Although I have hereinafter shown and described one specific embodiment of my invention, I do not wish to be considered -as limiting 1 myself to the precise details thereof, as there may be modifications and variations in some.

respects without departing from the spirit of the invention or sacriiicing any of the advantages thereof. l

Y Reference is to be hadto the accompanying drawings, forming a part of this specification, in which similar characters of reference indidate corresponding parts in all the figures.

Figure l is a top plan view of an ore-separator embodying my invention. Fig. 2 is a side elevation of the same, and Fig. 3 is a central vertical sectional view of the feed-pipe and funnel therefor.

In the accompanying drawings, wherein lan embodiment of my invention is illustrated, the

letter A designates the frame of the separator, which is constructed of any suitable material, such as wood or metal, and, as shown, in the present instance it is formed of top and bottom frames 1 and 2, respectively, substantially quadrantal in shape, such frames being spaced apart and connected by vertical standards 3. A beam or brace of similar material, as at 4, connects the vertical standards centrally thereof, and a similar beam, as at 5, eX- tends transversely of the top frame l. Resting on the bottom portion ofthe aforesaid main frame, as shown at 6, is a relatively shallow pan approximately circular in contour,v

adapted when the separator is to be used to contain mercury or quicksilver, and for the sake of convenience I shall hereinafterdesignate this receptacle the mercury-pan. Suspended above the mercury-pan is a cylindrical casing 7, open at both ends, the said casing or cylinder being of substantially the same dimensions transversely as the aforesaid mercury-pan, the lower edge-of said cylinder 7 being 'adaptedto be'brought into contact with the upper edge of the mercury-pan 6 and held,

in such abutting position, so as to form a tight joint therewith, the mercury-pan and the cyl-- inder in s'uch -instance being to all intentsand purposes one vessel. supported intheframevvork in such manner that it may, be adjusted vertically relative to the aforesaid mercury-pan, and means employed for accomplishing such an adjustment are clearly shown in Figs. l and 2. Secured to each corner of the top portion of the aforesaid main frame are plates, as shown at 8, eX- tending inwardly ,and carrying at their ends collars or sleeves, as at 9, which collars or sleeves are preferably interiorly screw-threaded and form bearings for the screw-rods 10. Such screw-rods are in turn at their lower ends connected with the aforesaid cylinder 7 by means of the brackets 11, which are provided at their outer ends with sleeves or collars 12. As will be observed by reference to This open cylinder is Figs. 1 and 2, there are four of these screwrods and four corresponding brackets,- the said brackets extending radially from .the cylinder. Mounted approximately near the top of each of the aforesaid screw-rods is-a-.horizontally-disposed sprocket-wheel 13, the teeth of which are adapted to engage the` endless chain 14, which extends around the aforesaid sprocket-wheels. It Will further be seen that one of the aforesaid screw-rods 10 is provided with a hand turning-wheel 15, by means of.A

which the aforesaid screw-rod carrying said wheel 1s turned or revolved 1n its bearing.

. By turning the wheel the chain is caused to shaft 25 and supported horizontally on the topy travel around said sprocket-wheel and in doing so will cause the revolutionY of each. of the aforesaid screw-rods 10 in the collars or brackets of the cylinder, which will consequently cause the aforesaid cylinder to be raised or lowered vertically relative to the mercurypan.

Extending upwardly from..the` transverse standards or beams of the top frame 1, approximately centrally thereof, are the brace-rods 16, which support at their upper terminals a collar, as at 17. This collar 17 in turn-forms a 'bearing for the funnel portion 18 of the feedafter described, and to cause a revolutionof the fan or blades I have secured. rigidlyto the` upper end of the aforesaid tubular shaft 19 a horizontally-disposed bevel-gear 23, which is adapted to be driven by a similar verticallydisposed bevelgear 24-` meshing therewith. It will be seen by reference to Fig. 2 that the gear 24 is revolved through the medium of a of theframe 1 in bearings or clamps 26, such shaft being turned or driven from a belt-pulley 27 by power obtained from. any suitable source.

From the above description of the construction of the machine and the arrangement. of the parts the operation may -be readily .understood. The. precious-metal-bearing material. is fed into the machine through the funnel-18 and drops down through the tubular shaft 19. The cylindrical shell or casing 7 having inthe meantime been screwed or adjusted sothat it abuts or. contacts with thel mercury-pan, as above described, and the pan 6 having therein mercury or4 Quicksilver, `Wateris pouredin orv supplied tothe cylinder-7 Whenthe metal-r;

bearing material has been emptied into the 'cylinder `through the funnel 1S-and the shaft vor-foreign matter which has been separated from the gold will rest upon the mercury in the pan. When it is desired to remove such foreign matter from the pan, it is only necessary to elevate the cylindeiI through the medium of the mechanism before described, and the water will immediately rushout through the opening or spacethus formed between the mercury-pan and the cylinder and carry with it such foreign matter.l The mercury-pan may then be removed and the gold collected in the usual manner. v

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A separator comprising a main frame, a two-part separating-tank therefor, means for adjusting one yportion of said separating-tank vertically relative to the other, a feeder for said tank, `and means for revolving the feeder, substantially` as set forth.

2. A separator comprising a main frame, a tank formed of two portions, an upper open portion and a lower pan-like portion, means for adjusting the upper portion vertically relative to the. other pan portion, such means comprising bearing-brackets secured to said upper portion,-.bearings mounted on the main frame, screw-rods extending through the said bearings on the. main. frame and engaging with thebrackets on the upper portion of the tank, sprocket-gears carried by said screwrods, and an-endless chain extendingaround said gears, the construction being such that when the chain is in motion, the gears and the screw-rods will be revolved and the upper portion of the tank adjusted vertically, substantially as set forth.-

3. A sectional separator comprising a main frame, a separating-tank, means for moving one .section of the .tank relative to another, and. means for feeding and distributing precious-metal-bearing material in said tank, such means comprising braces o n themain frame,
