Abstract
A counterweight is freely pivoted on a rotatably driven unbalanced eccentric weight member such that at start up the counterweight does not add materially to the unbalance created by the eccentric weight member and such that as the motor attains operating speed the freely pivoted counterweight is slung outward relative to the eccentric weight member thus adding unbalance to the eccentric weight member and increasing the vibratory forces generated by the apparatus.
