FRED D. FENN, OF BOISE, IDAHO.
AMALGAMATING APPARATUS.
To all whom it may concern:
Be it known that I, FRED D. FENN, a citizen of the United States, residing at Boise, in the county of Ada and State of Idaho, have invented a new and useful Amalgamating Apparatus, of which the following is a specification.
This invention relates to a novel amalgamating a paratus, designed more particularly for the separation of placer values from sand or other gangue.
The object of the invention is to produce a simple and efficient apparatus for conveying gold laden sand or pay dirt to the amalarnating tank and for removing the gangue from said tank.
T0 the accomplishment of the objects stated, the preferred embodiment of the invention resides in that construction and arran 'ement of parts to be hereinafter described, illustrated in the accompanying drawings, and succinctly defined in the appended claims.
In the accompanying drawingsFigure 1 is a general view of the complete apparatus. Fig. 2 is a detail perspective view of the amal gamating tank and interior parts. Fig. 3 is a plan view of the same subject-matter. Fig. 4 is a detail perspective view of the sand chute. Fig. 5 is a detail view of the upper end of feed spout or pipe. Fig. 6 is an elevation of the gangue conveyer or draper belt. Fig. 7 is a top plan view of the same. Fig. 8 is a detail perspective view of one of the buckets or scoops of the draper.
Each part is indicated by the same reference character throughout the views.
The primary element of the apparatus is a mercury tank 1 disposed at an inclination and having a deep lower end 1 and a shallow u per end 1 which extends a consider able istance above the level of the mercury a with which the lower end of the tank is filled. Disposed adjacent to the inclined bottom 1 of the tank 1 is an endless conveyer 2 in the form of a chain provided at intervals with carriers 3 and passed around peripherally grooved pulleys 4 and 5 located at opposite ends of the tank. These pulleys are mounted on shafts 6 and 7 retained in parallel relation by a bar 8. The shaft 6 is extended somewhat above the tank and is driven from a driving shaft 9 through the medium of beveled gears 10 and 11. The shaft 9 is equipped with a belt pulley 12 to Specification of Letters Patent.

Serial No. 312,644.
facilitate the belting thereof to a suitable source of power and is designed to drive the feed conveyer 2, as well as other conveyer-s to be described.
The downwardly moving side or run of the feed conveyer 2 is inclosed for the major portion of its length by a tubular feed spout or pipe 13, the lower end of which is curved concentric with the ulley 5 and extends within the peripheri l groove thereof, as shown in Fig. 3. The lower extremity 14 of the spout being located at the bottom of the tank and adjacent to the front wall thereof for the purpose of discharging the pay dirt or gold bearing sand at the bottom of that portion of the tank where the greatest depth of mercury occurs. The gold bearing sand is delivered to the feed spout 13 from a sand chute 15 inclined in the opposite direction from the tank and having its lower end arranged within the same and comprising a hood 16 and a hopper 17, the front and back walls of the latter being provided with apertures 18 through which the upper end of the feed spout 13 is extended, see Figs. 1 and 2.
The upper side of that portion of the feed spout 13 which is located within the hopper 17 is cut away to form an enlarged opening 19 through which the sand descends from the hopper 17 to the interior of the spout,-
through which it is conveyed to the Inercury bath by the .,conveyer 2.
The sand may be delivered to the sand chute in any suitable manner, but I prefer to employ an endless sand conveyor 20 extended upwardly from a suitable source of supply and passed around a pulley 21 mounted, within a hood 16, on a shaft 22. The shaft 22 is extended beyond one side of the hood and is geared as by a belt 28 to a countershaft 24 driven from the shaft 9 through the medium of beveled gears 25 and 26, Fig. 1. As the gold bearing sand is delivered continuously to the tank 1, the ascending run of the feed conveyor 2 serves constantly to agitate the mercury. The gold will amalgamate with the mercury in a manner well understood in the art, and the sand being lighter than the mercury, will rise to the surface of the latter.
As the sand or other gangue accumulates at the surface of the mercury a, it is removed by an endless conveyer or draper 27 mounted in what may be termed a draper frame 28 the side bars 28 of which are connected by shafts 29, 30, 31 and 32. The draper 27 includes two endless cables 27 a and 27 carrying and connected by buckets or scoops 33 provided at their opposite ends with eyelets 34 through which the cables are passed, see Figs. 6, '7 and 8. The buckets or scoops, which skim the gangue in a horizontal position, are shallow, flat and oblong and are open only at the front. Then the buckets or scoops are in a horizontal posi tion for skimming the gangue from the surface of the mercury, the bottom Wall is extended in advance of the top wall to provide a projecting lip, which facilitates the skimming operation. Each of the cables 27 and 27 is led over a set of pulleys 29 30 31 and 32 mounted respectively on the shafts 29, 30, 31 and 32. The pulleys 32 are comparatively large, while the remaining pulleys are quite small, the pulleys 29 and 30 being located in the same horizontal plane, but the pulleys 31 being slightly elevated relative to the adjacent pulleys 30 The dra er 27 is led from the upper side of the pul leys 32 over and around the pulleys 29 thence to the under side of the pulleys 30 and thence over the pulleys 31 to the under side of the pulleys 32 By this arrangement that portion or run of the draper extending between the pulleys 29 and 30 is disposed at the surface of the mercury, and the scoops are therefore enabled to remove the sand as they travel rearwardly. As the filled scoops pass from the pulleys 30 to the pulleys 31 they are turned to an upright position, but are inverted as they pass down from the pulleys 31 to the under side of the pulleys 32*. Therefore, it will be noted that as the scoops pass over the mercury tank, they gather up the sand accumulated upon the surface of the mercury, and having moved back beyond the tank, they are inverted to dump the material so gathered. The draper 27 may be operated in any suitable manner, but is preferably driven from the shaft 9 for which purpose the countershaft 24, geared as stated, to the driving shaft, is belted to the shaft 32 through the medium of a belt 35 and suitable pulleys.
To recapitulate briefly, the gold laden sand or pay dirt is carried from a suitable source of supply by the endless conveyer 20 and is dum ed into the sand chute 15, from whence it lows into the feed s out or pipe 13 and is conveyed thence by t 1e feed conveyer 2 to the bottom of the mercury tank 1. The feed conveyer 2 serves the double function of conveying the sand to the tank and of agitating the mercury. The gold amalgamates with the mercury in the tank a, and the sand, rising to the surface of the mercury, is carried ofi by the draper 27 and dumpe I That I claim is 1.
