ABSTRACT:
A volumetric feeder having a reversible motor, in which the feed screw is driven at a first speed when the motor rotates clockwise, and is driven at a second speed when the motor rotates counterclockwise. The feeder includes a first one-way clutch, having a driven inner race and an outer race which rotates freely counterclockwise relative to the inner race when the inner race is driven clockwise. The outer race of the first one-way clutch rotates with the inner race when the inner race is driven counterclockwise. A second one-way clutch has a driven outer race and an inner race which rotates freely clockwise relative to the outer race of the second one-way clutch when the outer race of the second one-way clutch is driven counterclockwise. The inner race of the second one-way clutch rotates with the outer race of the second one-way clutch when the outer race of the second one-way clutch is driven clockwise. The motor shaft is attached to the inner race of the first one-way clutch. A driven shaft is attached to the inner race of the second one-way clutch and is coupled to the feed screw. The outer race of the first clutch is coupled to the driven shaft to rotate the driven shaft at a first speed. The motor shaft is coupled to the outer race of the second clutch to rotate the second clutch and the driven shaft at a second speed which differs from the first speed.
