AMALGAMATOR AND CONCENTRATOR.

SPECIFICATION forming part of Letters Patent No. '7 55,230, dated March 22, 1904:.

. Application filed gJ'uly '1, 1902. Serial No. 114,652. (No model.)

To all whom, it may concern:

Be it known that I, KINSEY LANIUs, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of U010- rado, have invented certain new and useful Improvements in Amalgamators and Concentrators, of which the following is a specification.

This invention relates to amalgamators and concentrators for extracting gold and silver from ores.

The object of this invention is to provide an amalgamator and concentrator which will include an amalgamatingtrough provided with removable guards adapted to be locked therein and screen-sections which will dis charge fine particles of gold into lower amal- I gamating, reciprocating, concentrating and arrastra troughs, the upper and lower troughs having their outlets at opposite ends and inof fingers extending down in the amalgamating-pans, adapted to keep themercury-baths v therein in a state of agitation.

A further purpose of the invention is to construct a machine of the character described in a simple, light, and durable manner, and to provide mechanism for imparting end movement to the troughs simultaneously with a jerking or jarring motion.

In brief, my invention consists in' certain novel features, the particular construction of the various parts, and in the arrangement andcombination of said parts, all of which will be hereinafter fully described, and specifically pointed out in the appended claims, which are intended to accord in their terms, spirit, and meaning with the prior state of the art and the existing laws.

In the drawings forming a part of this specification, Figure 1 is a View in side elevation.

Fig. 2 is a top plan view, parts being broken.

away. Fig. 3 is a vertical longitudinal sectional view. Fig. 4 is a horizontal sectional view. Fig. 5 is a vertical transverse sectional view looking in one direction. Fig. 6 is a vertical transverse sectional view looking in the other direction. Fig. 7 is a detail view of the screen, illustrating the manner in which it is looked upon the frame. Fig. 8 is an enlarged detail-view of the ball-bearing sleeve.

The main frame A of the machine is preferably made of tubular material in the interest of lightness and is ordinarily rectangular in its general contour, comprising parallel upper side sections 1, lower side sections 2, vertical corner-sections 3, connecting the upper and the lower sections, upper end sections 4, and lower end sections 5, connecting the upper, lower, and corner sections, as shown in Fig. 1. Between the lower side sections are pivoted two shafts 6, carrying angular levers 7, having mounted upon one end of: each a wheel 8, the other ends being connected by parallel rods 9. One of these levers is connected by a rod 10- to a lever 11, mounted upon one of the corner-sections and provided with a suitable device for locking it in a depressed position, thus providing means "whereby "the frame may be easily raised upon the Wheels and readily conveyed from place toplace.

Within the main frame an auxiliary frame B is mounted to swing upon rods'12. The auxiliary frame Bis similar in construction to the mainframe, being usually rectangular and of less dimensions than the dimensions of the compartment of the mainframe in which it is placed, as shown in the several figures. This auxiliary frame B'consists of upper and lower end sections 13, upper and lower side sections 14:, and upright end sections 15, together with oppositely-disposed angular sections consisting of an upper and lower rods 16'and 16', held or braced together at their free end by a plate 18, the rods 16 and 16' having mounted there upon sliding tops 19 and 19, the purpose of which will be hereinafter described.

The auxiliary frame B carries an amalgamating-trough C at its upper portion, mounted upon the adjustable brackets 20, adapted to slide up or down on the upright end sections 15. This amalgamating-trough consists of a frame having upper and lower side sections 21, upright sections 22, connecting the upper and lower sections, end sections 23, connecting the side sections, and transverse sections 24, connecting the lower side sections. This frame is adapted to receive and support the trough proper, which is provided approximately near its open end with a strip 25 and perforated above the strip, as shown at 26, so as to form a screen. It is also provided with a screen 27, which is supported over the screen 26 by the strip 25. These screens extend from side to side of the trough and permit the fine particles of gold and fine ore which sifts through the openings in the guard E, to be hereinafter described, to pass down and out from the amalgamating-trough into a lower trough D, also to be hereinafter described, the coarse material in the amalgamating-trough C finding an exit at the lower or open end of said trough. This trough is further provided with a guard E, consisting of a series of steel strips 28, so shaped as to form inverted troughs, which are connected by transverse strips 29, bent so as to lock the parts together. This guard is formed in two parts adapted to rest in the bottom of the trough and to be locked therein by the rod 30, which extends across the trough and is adapted to be held in place by a lock 31. This guard has two functions,

one of which is to receive and carry off the coarse material and the other is to prevent the amalgam from being stolen from the trough.

It will be observed that by adjusting the supports or brackets 20, which may be fixed in position by suitable set-screws, the inclination of the amalgamating-trough may be increased or decreased, as occasion may demand. The inner surface of the amalgamating-trough Uis coated with mercury or otherwise treated for the purpose of causing the gold 'to adhere thereto and separate itself from the dross or crushed ore.

Below the amalgamating-trough C is a concentrating-trough D, which trough is inclined in an opposite direction from the upper or amalgamating trough, and the outlet of the concentrating-trough is at that end which is beneath the inlet portion of the amalgamating trough. The concentrating trough is likewise supported by adjustable brackets 32, adapted to increase or decrease the inclination, as occasion may demand, this trough consisting of a frame having upper and lower side sections 33, connected by upright sec: tions 34, upper and lower end sections 35, connecting the upper and lower side sections, and transverse sections 36, connecting the lower side sections. This frame supports the trough proper, which is provided with three amalgamating pans or reservoirs 37, 38, and 39, which are formed therein by suitable partitions, each pan being provided with a drainplug for the purpose of drawing off the mercury.

The reservoirs or pans 37, 38, and 39 are adapted to receive a mercury-bath and are likewise adapted to receive suitably-applied electric currents, as plainly shown in Fig. 3, wherein (0 indicates the negative wire, and 7) the positive wire. At thereceiving end of the concentrating-trough is a pivoted gate 41, which may be. opened or closed, as occasion may demand, so as to pass out the concentrates or force them to go through the amalgamating reservoirs or pans; also, an inclined directing-.plate42, adapted to receive the material which passes through the screens in the amalgamating-trough C and direct it to the center amalgamating-pan 38. Between the amalgamating-pans 37 and 38 is located an arrastra F, consisting of two blocks of stone, glass, or the'like, (designated, respectively, as 43 and 44. The lower block 43 is secured to the bottom of the trough D, while the upper block 44 is secured by means of adjustable rods 45 and 46 to a shaft 47, which is mounted between oppositely-disposed angular levers 48, pivoted upon the sides of a frame G, hereinafter fullydescribed, the free ends ofthe levers engaging the lugs 49 upon the frame of the concentrating-trough D for the purpose of giving a vertical motion to one end of the upper block when the auxiliary frame carrying said trough is swung back and forth.

As the concentrating-trough moves with the suspended or auxiliary frame B, the lower block 43 of the arrastra will be laterally reciprocated beneath theupper block 44. These blocks are one of the main features of my invention, as the gold which cannot be readily separated by the amalgamating trough and reservoirs or pans and by the action of suitably-applied electric currents will float up between the stones or blocks and will there be ground and separated from the dross and so polished or brightened that it will adhere to the mercury.

The frame G, consisting of side sections 50, connected by end sections 51, is mounted upon adjustable brackets 52 upon the stationary frame A. This frame is provided with transverse sections 53, connecting the side sections 50 and adapted to support corresponding plates 54, provided with a series of aluminium fingers 55, the lower ends of which are bent, so as to form paddles, which paddles extend down into the amalgamating reservoirs or pans 37 and 38 and serve to keep the mercurybaths in said pans in a state of agitation while the machine is being operated.

Over the frame G is located a screen H, which is supported upon the brackets 52 and locked upon the frame by a rod 56, which extends beneath said frame and is provided with a lock 57. This screen covers the entire frame and projects over the ends and sides of the concentrating-trough, thus rendering it impossible to steal the amalgam and quicksilver therefrom. i i

The auxiliary or suspended frameB is given end motion through the medium of cams 58, which are mounted on a transverse shaft 59, journaled upon theend uprights of the stationary frame A, said shaft being driven by a pulley 60. These cams consist of disks having corresponding ball-bearing sleeves 61, adapted to engage the adjustable stops 19 or 19 alternately. The object in having these stops, adjustable is to provide means for reversing the motion of the machine, which may be accomplished by adjusting one set of the stops so that they will be brought in contact with the revolving sleeves and the others out of the line of contact, and vice versa, the bottom portion of the auxiliary frame being connected by a tension device with the bottom portion of the main frame A, and these tension devices are so placed that when the auxiliary frame is forced to move in one direction by the cams and is released by said cams the tension devices serve to return the auxiliary frame to its normal position. sion devices, as shown, consist of cylinders 62, adapted for attachment to either end of the main frame at opposite sides, and a spring-- controlled plunger 63, having movement in said cylinder, the outer end of the plunger being connected by a rod 64 to an angular lever 65, pivoted upon the bottom side section of the auxiliary frame and adapted to be held in a depressed position by the lugs 66 or 67 as occasion may demand, these tension de-' vices being adjustable, so as to give the desired strength to the jerking or jarring motion and to register the number of pounds required to the jerk or jar to work the ore.
