Abstract: A two-way vibratory conveyor includes at least one trough mounted on a base and a drive which reciprocally moves the trough(s). The conveyor, which in one embodiment has two interconnected troughs and in another embodiment has a single trough, includes a drive which uses a single motor. In the two-trough conveyor, the two troughs are driven in opposite directions. In the single-trough conveyor, the single motor is used to selectively drive the trough in one of two opposite directions. The troughs are mounted to a base using springs and stabilizer arms. The stabilizer arms, which are made of ductile iron, have been found to be withstand larger loads and have a longer useful life than currently available stabilizer arms.
