AMALGAMATO R.

SPECIFICATION forming part of Letters Patent No. 240,548, dated April 26, 1881. Application filed December 1, 1880. (No model.)

To all whom it may concern:

Be it known that I, DANIEL EUGENE Rose, of Brooklyn, in the county of Kings and State of New York, have invented a new and Im proved Amalgamator, of which the following is a specification.

Figure 1 is a sectional side elevation of my improved amalgamator. Fig. 2 is a horizontal section of a modification thereof. Fig. 3 is a vertical cross-section of said modification. Figs. 4 and 5 are vertical sections of other modifications, and Fig. 6 is a side view of the C enters the kettle, the proper plan is to compact it or pack it tightly, so as to preventair from entering the lower end of the kettle, and prevent the lead from finding its way out of the kettle into the ore-supply channel.

My present invention embraces the following principal feature, in that it consists in so constructing the apparatus that the ore will be packed into a compact mass, so to say, on

its entrance tgthe kettle of lead, and as this;

compacted mass-ispushed fbnward by the mechanism which I shall describe, part of it will reach the molten lead in the kettle, and will at once expose its auriferousand argentiferous constituentsto the-iamalgamating action of the lead, whereas the other particles of the ore will float on top of the lead, whence they can be removed by suitable appliances.

In the accompanying drawings, the letter A represents a suitable kettle for containing molten lead. This kettle is placed into' a suitable furnace, B, in which furnace a fire is started for keeping the lead in the kettle in molten condition. The lower part of the kettle A has a 'supply=opening, a, which is of slightly-tapering form, as shown in Fig. 1, being larger at its cuter than at its inner end. To this funnel end of the mouth a is clamped, by means of a suitable ring, 0, the ore-supply tube D, that extends from the ore-hopper E.

Within the tubeD is a screw, F, for gradually forcing the ore containing the gold or silver into the kettle, and as the screw is revolved by suitable mechanism the ore will become compacted into the narrowing mouth a of the kettle, and will there pack and form a cushion to prevent air from reaching the lead through the. hopper E, pipe D, and mouth a. The continued rotation of the screw F forces the packed ore gradually into the kettle, and causes it to be exposed to the amalgamating and carrying effects of the molten lead, so that the silver or gold actually contained in the orc will be retained by the lead, whereas the impurities will float on top ofit.

For some kinds of ore the screw F would not be a desirable means of feeding the same forward, and in such cases I substitute for the screw either reciprocating pusher-rods G, such as are shown in Figs-2 and 3, or a rotating bladed disk, H, such as is shown in Fig. 4, or an oscillating cam, I, such as is shown in Fig. 5. In fact, any mechanism for pushing the quartz or ore that enters the tube D from the hopper E forward toward the contracting mouth of the kettle is by me regarded as the equivalent of the screw F.

I claim 1. In an amalgamator, the combination of the kettle A, having the flaring mouth. a, which is larger at its outer than its inner end, with the ore-supply pipe D, and with mechanism for pushing the ore into the mouth a, and compacting it therein, substantially as specified.

2. The combination of the kettle A and furnace B, said kettle having the flaring mouth a, which is smallest near said kettle, with the ore-supply pipe D, screw F, and clamping device O, all arranged for compacting the ore in the mouth a, substantially as specified.

DANIEL EUGENE ROSE.
