GOLD-WASHER.

SPEGIFICATION forming part of Letters Patent No. 612,034, dated October 1 1, 1898.

Application filed August 23, 1897. Serial No. 649,121. (No model.) I

the invention, such as. will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in gold-washers or ore-separators.

The primary object of the invention is to provide a device of this character with which the auriferous sand and dirt containing free gold can be effectually worked to obtain therefrom the maximum amount of gold.

The invention further contemplates the provision of a gold-washer that will be especially simple in construction, durable, economical, and one with which the sand or dirt containing the gold can be conveniently handled throughout the entire process of separating said gold from the sand or dirt.

lVith these and other objects in view, which will become apparent in the course of the following description, the invention consists in the novel combination and arrangement of simple parts which will be hereinafter fully described, and the points of novelty will be particularly set forth in the claims.

I am enabled to accomplish the objects of my invention by the simple means illustrated in the accompanying drawings, in which- Figure 1 represents a top plan view of my improved gold-washer. Fig. 2 is a side elevation thereof, the tank or tub being partly broken away. Fig. 3 is a central sectional view of the gold-pan. Fig. 4. is a bottom plan of false bottom. Fig. 5 is a longitudinal sectional view of the rough-washing box, tailings-box, settling tank, and dirt-box, showing their relative positions.

Referring to the drawings, the numeral 1 indicates the tank or support, consisting of a platform 2, having hinged legs 3 and 4 secured to the under side thereof and held in unfolded position by hooks 5 and 6, the hook 5 being secured to the leg 3 and adapted to enter an eye on the under side of the platform.

The hook G is secured to the leg tand is adapted to enter an eye 6 on the rear side of a crane-post 7, hinged to the platform by means of a hinge 8. On the inner face of said cranepost I provide two eyes 9 for the passage of the vertical arms of a crane 10, whose lower end is adapted to rest upon a support 11,

formed, preferably, of a single piece of metal extended downwardly and bent to form a short vertical arm 12, adapted to engage the edge of a tank or tub 13 to hold the same in position upon the platform. The crane is provided at one end with a hook 14, adapted to enter one or the other of links 15, secured to a handle-bar 16, which in turn is secured to a bracket 17, carrying a hoop 18 at its lower end, upon which is adapted to rest the annular flange of the gold-pan 19.

The numeral 21 indicates a perforated false bottom adapted to rest upon the bottom of the gold-pan, and said false bottom is provided upon its under side with flanges 22, which serve as agitators to loosen the sand or dirt and free the same from the gold. The false bottom 21 is provided with two inclined arms terminating in short Vertical arms 22, adapted to be embraced by loops or rings 22", carried upon the lower ends of the bracket 17 and it will be apparent that said links are adapted to slide upon said brackets, thus per mitting the perforated false bottom to be removed. It will further be noted that the gold-pan is also removable.

Secured to the upper edge of the tub or tank 1 3 is a pan-rest 23, formed, preferably, of a single piece of metal bent into loop or U shape with the ends of its arms to form two Vertical arms 24, recurved upon themselves to embrace the upper edge of the tub, in which tub is a tailings-pan 24.

The numeral 25 indicates a coarse washer having its forward end raised and supported by a hinged support or leg 26, and its rear end is adapted to rest upon a block or support 27, and said washer is provided with books adapted to engage eyes 28, carried by the main support. In practice I arrange under the raised end of said Washer a settlingtank 28, having resting upon its rear portion immediately below the raised end of the washer a tailings-box 29.

The numeral 30 indicates a box or trough having its forward end resting upon the rear edge of the coarse washer 25 and having its other end supported by a hinged support 31, and said trough is adapted to receive the earth or sand containing the free gold, and during the preliminary steps of the process of separating the gold the earth or ore containing the same is manually fed from the box or trough 30 into the coarse washer 25, from whence the concentrates are raked into the tailings-pan, when the water will pass through the perforations in the tailings-box and drop into the settling-tank.

In operation the substance containing the gold is first washed, and the concentrates are then placed in the gold-pan and water introduced therein, and when the pan is worked the water forces the undesirable material through the perforations of the false bottom and allows it to pass from the pan, while the heavier materials remain. The tailin gs after leaving the gold-pan fall into a failings-pan which I provide, preferably, in the bottom of the tub or tank, while the water drops into the said pan and tub.

From the foregoing description it will be obvious that the device described is especially simple in construction and that by reason of providing a horizontal swinging crane a great quantity of material containing the gold can be conveniently handled.

It is obvious that the invention is susceptible to many minor changes and modifications involving mechanical skill which may be made within the scope of the invention without departing from the spirit thereof.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A gold-washer involving the combination of a suitable support, a crane-post connected with said support, a horizontal swinging crane sustained by said post, a gold-pan suspended from the crane, said pan being provided with a perforated removable false bottom having vertical arms and rings or loops for detachably securing said false bottom to the gold-pan, substantially as and for the purposes set forth.

2. In a device of the character described, comprising a suitable platform, a crane-post hinged upon said platfo1'm,a horizontal swinging crane upon said crane-post, a hoop suspended from said crane, a gold-pan provided with an annular flange 'on the upper edge thereof adapted to rest upon said hoop and perforated false bottom adapted to rest in the gold-pan, said false bottom being provided with flanges or agitators on its under side for the purpose set forth, means for securing said false bottom to the gold-pan, and a tub or tank upon the support beneath the goldpan containing a tailings-pan, substantially as described. 7

3. In a device of the character described, the combination with a platform having supporting-legs hinged thereto, a crane-post hinged to said platform, a horizontal swinging crane carried by said post, a handle-bar connected to said crane by links, members secured to said handle-bars and provided at their lower ends with a hoop, a gold-pan formed with a flange on the upper edge thereof adapted to rest upon said hoop, a perforated false bottom in said pan having arms adapted to be secured to the lower portions of said member or members by sliding links, said false bottom being provided on its under side CHARLES GRIMEU.
