ABSTRACT:
Scrap metal pieces are conveyed from a mechanical press by a shaker conveyor having horizontal and parallel spaced elongated trays supported for reciprocating linear movement above a compact drive unit attached to and supported by the press. The drive unit includes an electric motor having a shaft connected to rotate an elliptical input gear on an eccentric axis and in continuous mesh with an elliptical output gear eccentrically connected to an output shaft. A rocker arm and link assembly is eccentrically connected to the output shaft and oscillates in response to rotation of the output shaft. The assembly is pivotally connected to a support carriage for the trays for reciprocating the trays with rapid acceleration and rapid deceleration at one end of the linear stroke of the carriage and trays. The elliptical input and output gears are identical in size and have the same odd number of teeth.
