Abstract

An air vacuum extractor self contained power unit capable of extracting gold from crevices in rock by vacuum means. The vacuum extractor includes two gold pans. One pan has a power unit mounted on the bottom side thereof and is provided with intake and outlet hoses and includes a frame mounted to it. The second gold pan is fastened to it with a band to seal the air out. The bottom pan acts as a container. When the bottom pan is full it is unfastened and used as a gold separation pan.

SUMMARY OF THE INVENTION DESCRIPTION OF THE DRAWINGS FIG, I is a side view of the extractor.
FIG. 2 is an exploded view of the pan unit with the binder removed, showing the pans and seal.
FIG. 3 is a top view of the binder removed from the pan unit.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail wherein like reference characters like parts throughout the several figures the reference numeral 10 indicates generally an air vacuum extractor constructed in accordance with the invention.
In FIG. 1 the air vacuum extractor 10 includes a round base frame made of two gold pans with the two cycle 1 or 1.6 H. P. gasoline engine 30 connected to exoster 38 by belt 36 with pulleys 32 and 34, 12 pair of supports, 14 intake, 16 outlet, 18 a gold pan as a canister means or container, 22 a binder, 20 hinges, 24 filter, 26 intake hose, 28 outlet hose, safety guard and handle are not shown.
In FIG. 2 it shows 10 the canister as base, 14 intake, 40 seal, 18 gold pan, 12 pair of supports.
In FIG. 3 is 22 binder, 20 hinges, 42 lock. The main object of this apparatus is lightness and compactness.
I claim:
I. A device for collecting and separating heavy minerals comprising a housing unit formed of upper and lower gold recovery pans connected edge to edge with sea] means therebetween, leg means attached to said upper pan for supporting said device, a vacuum pump having an internal combustion drive motor mounted on said upper pan, a filter extending across said upper pan dividing said housing into upper and lower, chambers, an opening in said upper pan located in said upper chamber, a flexible hose extending between said opening and the intake of said vacuum pump, another opening in said upper pan located in said lower chamber, a flexible hose connected to said opening in said lower chamber for collecting material from crevices or the like, and said lower pan being readily detachable from said upper pan whereby said lower pan is operable by hand to separate heavy minerals from the material collected therein.
