  • Patent number: 5957303
    Abstract: A plurality of water cups (80) are mounted at the outer periphery of a rotating gold pan (12). In use, the gold pan (12) is supported in a rearwardly leaning position with a lower edge portion in water. During rotation of the gold pan (12), the water cups (80) collect water as they rotate into and through the water. The water cups (80) lift the collected water as they rotate up out of the water. The water cups (80) release water that they carry into the gold pan (12). The released water helps separate gold particles from other particulate material and moves substantially clean gold particles along the valleys (69) of the bottom wall (52) of the gold pan (12) to a hub cup (54).

  • Patent number: 5788293
    Abstract: A separator for separating gold particles from ore including a rotatable pan, and frame for mounting the pan through a recessed hub cup assembly at an angle from horizontal. The pan includes a frusto-conical side wall. The pan inner surface also includes a riffle spiraling inwardly from the outer end of the side wall to create loops that spiral to the hub cup. The riffle and the pan inner surface form a slide track in which the gold particles move along the riffle to reach the hub cup. One of the improvements includes a plurality of agitator knobules that are positioned between the loops of the riffle. Another feature is an easily removable insert cup inside the hub cup for easy collection of gold. In use, ore is introduced into the pan during rotation. Particles are agitated by the knobules to separate the particles from the ore and aid the particles down the slide track, moving the particles inwardly along the riffle into the insert cup.

  • Patent number: 5275294
    Abstract: A separator pan (10) is set into a rearwardly leaning position (FIG. 4 ). A lower portion of the pan sidewall (28) slopes downwardly as it extends outwardly from the pan bottom (12). A spiral rib (32), inside of the pan (10) slopes upwardly as it extends axially outwardly from the interior of the pan (10). Pan (10) is rotated in a direction causing the spiral rib (32) to coil inwardly. Large particles of gold ore, introduced into the pan (10), gravitate out from the pan, owing to the sloping nature of the lower portion of pan sidewall (28). Smaller particles, including small particles of gold, are trapped between spiral rib (32) and sidewall (28) and bottom wall (12) of pan (10). As the pan (10) rotates, these small particles are moved inwardly and into a hub cup (14).
