摘要： A two-way drive for horizontally vibrating a feeder bed, including a reversible drive rotating one of two drive shafts rotatably connected so that the second drive shaft rotates at a speed which is a selected ratio (at least 2:1) of the speed of rotation of the first. A first eccentric weight is rotatably secured to the first drive shaft. A second eccentric weight is rotatably secured to the second drive shaft and movable between a first position on a first shaft radius when the second shaft is driven in one direction and a second position on a second shaft radius when the second shaft is driven in the reverse direction. The first and second shaft radii are spaced from each other so that the second eccentric weight in the first position is aligned with the first eccentric weight in one concurrent rotational position on one side of the drive shafts to provide a maximum force in one horizontal direction when driven in the one direction, and the second eccentric weight in the second position is aligned with the first eccentric weight in an opposite concurrent rotational position on the opposite side of the drive shafts to provide a maximum force in an opposite horizontal direction when driven in the reverse direction. In the highly preferred form, the selected ratio is 2:1 and the first and second shaft radii are spaced apart 180 degrees. Two stop members in a cylindrical cage on the second drive shaft selectively engage the second eccentric weight, one when in the first position and the other when in the second position. A longitudinally extending feeder bed is supported in a horizontal orientation by an assembly permitting horizontal movement of the feeder. The drive is connected to the feeder bed with its drive shafts generally horizontal and transverse to the longitudinal direction of the feeder. The drive-feeder connection transmits forces in a horizontal direction.
