Specification of Letters Patent.

Patented Nov. *7, 1916.

Application filed February 10, 1915. Serial No. 7,327.

To all whom it may concern:

Be it known that I, LYNN W. BARBER, a citizen of the United States, residing at Hetland, in the county of Kingsbury and State of South Dakota, have invented'new and useful Improvements in Concentrators, of which the following is a specification.

My invention relates to improvements in concentrators for ore separators of the reciprocating type, and particularly to improvements in the construction of .the' separating elements proper whereby the precious metal is separated from the material by which it is carried.

The primary object of the invention is to provide a novel construction of concentrating or separating mechanism, by means of which the material is carried through a long range of travel within acomparatively small working area and subjected throughout such course to separating actions by which maXimum eiiiciency of operation is secured.

A further object of the'invention is to provide a construction of mechanical concentrator or separator which is economical in construction and operation.

The invention consists of the features of construction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawings in which Figure 1 is a side elevation of a concentrator or separator embodying my invention, showing only so much of the frame and operating mechanism as is necessary to illustrate the invention. Fig. 2 is a top plan view of the same, some of the agitator blades. being omitted. Fig.3 is a sectional plan view on the line 33 of Fig. 1. Fig. 4 is a vertical longitudinal section through the separating devices at one side of the center of theapparatus. Fig. 5 is a horizontal transverse section on line 55 of Fig. 4. Figs. 6, 7 and 8 are respectively, perspective views of the central pan of the upper separating series, one of the intermediate separator pans of the series, and the central separator pan of the bottom section or series. Fig. 9 is a detail view of one of the agitators. Fig. 10 is a detail View of the operating shaft.

In carrying my invention into practice, I provide a separating mechanism which includes a main frame 1 which may be of ordinary construotion, and superposed reciprocating tables or

separator frame sections

2 and 3, which are reciprocated simultaneously in opposite directions through the med um of suitable mechanism, such as the crank and pitman or eccentric and pitman devlces commonly employed.

. The tables or

frame sections

2 and 3 respectively carry upper and lower sets or serles of separating devices, the said sets or series of devices'each consisting of a series of separating pans, the pans of the upper ser es being adapted to receive the material, which is passed therefrom to the pans of the lower series, the tailing's being finally discharged from one of the pans of the latter.

The pans of the upper series consist of a central pan 4, which constitutes a receiving and separating pan, and a series of plain separating pans 5 on opposite sides thereof, while'the pans of the lower separating series consist of a central separating and discharge pan 6 and plain separating pans 7 oniopposite sides thereof.

The pan 4 is made of sheet metal and is of rectangular or oblong rectangular form, and is provided with an imperforate bottom, side .walls 8 and end walls 9, the said end walls 9 being of materially less height than the side walls, while each of the

pans

5 and 7 which are also made of sheet metal, and of rectangular or oblong rectangular form, is of less dimensions than the pans 4 and 6 and comprises an imperforate bottom 10, side walls 11, which are of equal height, and

end walls

12 and 13, the wall 12 being placed at the receiving end of the pan and being higher than the end wall 13, which is at the delivery end of the pan.

The pans 5 of'the upper section of the separator are arranged'in equal numbers on opposite sides of the pan 4, and the pans on each side of said pan 4 are arranged on an inclined plane, in stepped relationship, said pans 5 extending 'on opposite sides at an outward and downward angle of inclination to the pan 4. The arrangement of the pans is such that the short end wall of each pan abuts against the long end wall of the adj acent pan, thus establishing communication between said pan to provide stepped and riflied chutes on opposite sides of the central pan 4, for the downward flow of the material under treatment by gravity. The sides of the pan are fastened by rivets or bolts 14 to strips 15 which are secured to the reciprocatory frame section, and for the purpose of connecting the adjacent ends of the pans suitable connecting means may be provided. In the present instance I have shown the short wall of each pan formed with a clown-turned hooked or channeled portion 16 which engages the edge of the long wall of the next adjacent lower pan, and so on throughout the series, said parts being united by bolts or rivets 17, whereby a firm coupling connection is effected.

The central pan 1 of the upper series is disposed at the center and highest point of said series, from which the pans 5 extend downwardly'to form stepped and inclined planes, while the pan 6 of the lower series is arranged at the lowest point of said series and the pans 5 thereof extend upwardly and outwardly therefrom on stepped and inclined planes and underlie the pans of the upper series. The pan 6 is similar in construction to the pan 4 except that it is provided with outlets 18 for the discharge of the tailings, as hereinafter described.

Associated with each set or series of pans are agitators 19 which extend across the bottoms of the pans and consist of concavo convex strips of metal having right angularly bent end portions 20 secured to carrierbars 21, which carrier bars are adjustably fastened to the main frame by fastening devices 22, which permit the sets or series of agitators to be disposed at a greater or less elevation above the surfaces of the pans to regulate their action on the material. In the operation of the device the agitators, being fastened to the main frame, remain stationary, while the pans reciprocate with the reciprocating table or frame sections, and hence their relative motion between the pans and agitators is established whereby the material under treat ment is kept in constant motion, as will be readily understood.

Any suitable means may be employed for simultaneously reciprocating the sets or series of pans in opposite directions in unison. In the present instance, I have shown pitman rods A and B pivotally connected at their outer ends with the top and bottom series of pans and at their inner ends with the cranks C of a centrally disposed transverse operating shaft O suitably journaled on the main frame 1. The cranks C are arranged at an angle of 180 to each other, and therefore project beyond diametrically opposite sides of the shaft, whereby as the shaft revolves the two sets or series of pans will be simultaneously reciprocated in opposite directions in an obvious manner.

In the operation of the separator, which is more especially designed for separating gold from sand, the gold bearing material with a proper supply of water is led from a conductor into the receiving pan 4, from which divisions thereof pass to the pans 5 on opposite sides thereof and flow downwardly along and through said pans 5,

make the water and sand, as well as the particles of gold which are not collected by the upper pans 5, discharge from the terminal pans 5 of the upper series into the outer pans 7 of the lower series and thence passing over and down the same to the discharge pan 6. It will thus be evident that V in their course of travel the streams of water and the gold bearing material flow from pan to pan of the upper series in which the heavier particles of gold are deposited by their greater specific gravity, and thence flow into the lower pan 7 in which the small particles of gold are deposited and so on until all of the gold is separated from the sand and water, which discharge through the openings 18 in the pan 6 into a suitable tailings trough or receptacle. It will be observed that the pans 7 of the lower series are greater in number than the pans 5 of the upper series, so that certain of the pans 7 will always be in position to receive the material flowing from the outer pans 5, thus preventing any possibility of waste. Inasmuch as the two sets or series of pans are reciprocated in opposite directions simultaneously, whereby motion is communicated to the material, and as the material is also agitated, turned over and kept in a constant motion by the flowing water, agitators and surfaces of the pans, it will be obvious that a thorough washing of the material and freeing of the gold therefrom for deposit in the pans will be effected. The construction of the device 100 also provides a long line of travel for the material within a comparatively short area, by which the efficiency of the apparatus is materially increased.

I claim 1. A separator of the character described comprising an upper series of separating pans consisting of a central receiving pan having outlets at its opposite sides and gradient rows of pans arranged on oppo- 10 site sides thereof and extending at an outwardand downward angle in stepped relationship, a lower series of pans having a central discharge pan provided with outlets at its opposite sides and gradient rows of 11.5 pans on opposite sides thereof and extending outwardly and upwardly in stepped relation, the pans of the lower series being arranged to receive the material flowing from the terminal pans of the upper series, and 120 means for establishing relative motion between the pans of the respective series to effect movement of the material being separated.

2. A separator of the character described 125 comprising upper and lower sets of separating devices, each consisting of a'central pan and separating pans on opposite sides thereof, the separating pans of the upper series inclined outwardly and downwardly 130 from the center pan and the separating pans of the lower series inclined outwardly and upwardly from the central pan thereof, the separating pans of each set being arranged in stepped relation and the central pan of the lower series being provided with an outlet for the tailings, and means for reciprocating said pans.

3. A separator of the character described comprising upper and lower series of separating pans, each including a central pan and separating pans on opposite sides thereof, the separating pans of the upper series being inclined downwardly and outwardly from the central pan thereof, and the separating pans of the lower series being inclined outwardly and upwardly from the central pan thereof, said central pans respectively serving as an inlet and outlet, and means for imparting relative motion to the upper and lower sets or series of pans.

4. A separator of the character described including an upper series of pans, consisting of a central receiving pan and stepped sets of separating pans inclining downwardly and outwardly at opposite sides thereof, a lower series of pans including a central discharge pan and separating pans arranged in stepped order and inclining upwardly and outwardly on opposite sides thereof, the pans of the lower series being greater in number than the pans of the upper series and adapted to receive the material therefrom, and agitators within the pans, supporting means for holding said agitators stationary, and means for imparting relative motion to the sets of pans.

In testimony whereof I aflix my signature in presence of tWo witnesses.
