ABSTRACT:
A mechanical vibrator assembly adapted to be attached to a device to be vibrated and wherein a shaft has a first weight system eccentrically fixed to the shaft, and a second axially displaced balancing weight system rotatable on the shaft. Stop surfaces limit rotation of the second weight system to approximately 180.degree., from a counterbalancing position substantially 180.degree. removed from the first weight system to a shaft vibrating position just short of circumferential alignment with the first weight system. A motor drives the shaft in a direction of rotation such that a slackening of speed removes the second weight system to the 180.degree. removed balanced position.
