Abstract
A traditional gold pan 10 with a flat center base 11 with a spiral sidewall guide 20 from a vertical pan rim 13 to the pan base 11 incorporates a plurality of obtuse flukes 30 on the spiral extending into the spiral path to disrupt smooth flow of water and mineral matter. A spiralling guide is also provided on the base 11 leading to a cup 60 at the pan center. On the spiralling base guide 40 is a plurality of stratifiers extending from the guide base 40 into an outer spiral path. The pan is continuously rotated by an electric motor linked to the back of the by a belt and pulley.
Claims19
A traditional frustum gold pan closed with a flat base at its smaller end and a sidewall inclined from the pan base to a pan rim defining a concave pan front and a pan back, the improvement comprising
- a sidewall guide on the pan front with an inner side and an outer side in a spiral progression around the sidewall from the rim to the base,
- a plurality of flukes on the sidewall extending from the sidewall guide inner side stopping short of a next inward sidewall guide in its spiral progression to the base.
A traditional frustum gold pan closed with a flat base at its smaller end and a sidewall inclined from the pan base to a pan rim defining a concave pan front and a pan back, the improvement comprising
- a cup in the pan base center extending out of the pan back,
- a spiraling base guide on the pan base, with an inner side and an outer side, ending at the cup in the pan base center, and at least four stratifiers located within two full revolutions of the ending of the spiraling base guide.
A traditional frustum gold pan closed with a flat base at its smaller end and a sidewall inclined from the pan base to a pan rim defining a concave pan front and a pan back, the improvement comprising
- a pan rim extending upward from the pan sidewall near and approximately normal to the plane of the pan circumference, with the spiral guide meeting and obliquely merging into the pan rim,
- a plurality of flukes on the rim extending from the rim inner side.
