AUTOMATIC GOLD-COLLECTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 568,657, dated September 29, 1896.

Application filed November 11, 1895. Serial No. 568,624. (No model.)

Qo alt whom it may concern;

Be it known that I, JOHN REITTER BROWN, mine-operator, of Harrison Hot Springs, in the Province of British Columbia, Canada, have invented a certain new and Improved Automatic Gold Collecting Apparatus, of which the following is a specification.

The object of my invention is to devise an automatic apparatus for collecting gold from tail, substantially as hereinafter more particularly described and then definitely claimed.

Figure 1 is a cross-section of the apparatus. Fig. 2 is a perspective view of the same with parts broken away. Fig. 3 is a detail of the gates of the f unnel-cylinder. Fig. 4 is a plan view of the top of the convex bottom of the apparatus. Figs. 5 and 6 are plan views of the amalgamated plates. Figs. 7 and 8 are details of the mercury-pockets.

In the drawings like letters of reference indicate corresponding parts in the diiferent figures.

In Figs. 1 and 2, A is a cylindrical cage built up of fiat iron bars 13, set in rings C, located either, as shown in the drawings, at the bottom of the cylinder and on a level with the upper and lower ends D and E of the funnel-cylinder F or at any other suitable point. The rings 0 rest, as shown, on the ring P and the ends of the funnel-cylinder, respec tively, though any other detachable form of construction would suit the purposes of my invention. At the circumference of the funnel-cylinder these bars B are set to direct the water entering the cylinder toward the center; but in the lower part of the cage they are twisted, so as to direct the current obliquely inward, while guarding against the entry of coarse gravel into the interior of the cage.

G is the convex bottom of the cage, resting on the ring P and provided with mercurypockets H, as hereinafter described.

I is a vertical tube, having a nut J screwed on its lower end, on which the convex bottom G rests. This tube extends up to the lower 'end E of the funnel-cylinder, where it is connected with a skeleton tube K by means of a threaded sleeve L. M is an extension connected to the upper end of the skeleton tube K. On the upper end of this extension is fitted a spider N, the arms of which extend to the outer circumference of the cylindrical cage. On the ends of these arms are pivoted the wings 0. These wings comprise the sheetmetal portion P, connected to the bar Q, having pointed ends R to engage with the soil at the bottom of the stream. On the back of each bar Q, close to the pivot, is a lug S, adapted, when the wings are in the position shown in Fig. 2, to rest on a ring T. To this ring T are connected suitably-supported vertical rods U, which extend below the bottom of the cylindrical cage A. lVhen the cage is lowered in position in the stream, these rods are'pressed upward, thus raising the ring and throwing downward the wings 0, so that their points enter the bed of the stream and steady the cage. These wings serve also to direct the flow of the stream through. the cylindrical cage.

The funnel-cylinder F is divided by radial partitions V, so that water entering the cylinder is directed to the center and its flow concentrated and intensified. At the center of the funnel-cylinder are located the gates W',-hinged at a and opening inward. Their outward motion is limited by the stops Z), against which they are held by means of light springs c on the hinges.

From this construction it follows that the Water entering the funnel-cylinder at one side is directed to the center, opens the gates on that side, and passes down the skeleton tube K and vertical tube I, the gates opposite the points of entrance being held closed by the internal pressure of the water. There is in consequence a strong current directed down the tube I, which passes out through the openings X at the lower end thereof. This current, flowing over the bottom G, keeps it clear of all accumulations of sand and gravel.

' plate D is slightly convex and has its outer tipped.

edge resting on top of the rings A. The other plates are all slightly concave. Each plate is provided with a series of mercury-pockets ll, hereinafter described. These plates may be corrugated in different ways, but in Figs. 5 and (5 I show preferable arrangements, Fig. 5 being the lowest plate,and Fig. 6 one of the upper plates.

E are a series of rings resting on shoulders on the collars B. From these rings ribbons F extend, having loops G formed on their outer ends.

Surrounding the upper part of the tube I is a sleeve ll, having flanges around its circumference, to which are attached a series of concave steel wings II. The outer edge of each wing extends to the inside of the cylindrical cage, while the inner edge is shaped to fit the outer edge of the cone formed by the plates D. It will be seen that these wings are not setin a plane radiating from the center of the cylinder, but that the lower edge of each is set forward to give the wings a slanting position. I are a series of perforations formed in these wings, through which are passed the loops G on the ribbons F, where theyare secured by suitable pins. From this construction it follows that the waterenterin g the cage will rotate the wings, thus sweeping the ribbons F over the surfaces of the plates D and working any sand or light gravel which may be resting upon them gradually toward the center,from which it drops through between the arms 0' to the bottom of the cylinder and is thence swept outward by the central current from the tube I; lhe shape and position of the wings II also serve to create an eddy in the water and distribute it between the various plates.

The mercury-poekets,hereinbefore referred to, are constructed substantially as shown in Figs. 7 and S.

J are flanges formed around the edges of the pockets which engage with clips K, riveted or otherwise connected to the lower sides of the various plates. The pockets are preferably provided with partitions L to prevent spilling of the mercury when the apparatus is To further provide against this contingency, each pocket II is provided with overflow-pockets M, communicating by openings N with the main pocket. These openings are preferably protected by shields O to prevent foreign matter entering the overflowpockets.

' their connections removed.

It should be mentioned that the convex bottom G, the rings A, and the plates D are made of copper, while the rest of the apparatus is preferably constructed of iron or steel.

\Vhen the machine is lowered in position in the stream, the wings O, as already described, act as braces to support the cage, through which the water, sand, and lighter gravel pass, as already described, the latter emerging from the machine completely deprived of the gold. A buoy will of course be attached to the apparatus to indicate its position in the river.

lVhen it is considered necessary to remove the amalgamated gold from the machine, it is raised from its position and the wings O and The cage is lifted from its position and the rest of the machine may then be readily taken apart and the plates scraped and reamalgamatcd. The machine may then be put together and again lowered in position in the river.

Instead of corrugated amalgamated plates, blankets or other woolly surfaces might be substituted.

Man y other changes in the construction might also be made without departing from the spirit of my invention.
