ABSTRACT:
A sanding plate is mounted in a housing with freedom of gyratory motion, and a rotatable eccentric shaft is journalled in the housing and connected with the plate for imparting the motion to the latter. A pneumatically powered rotary piston engine is mounted in the housing and connected with the shaft for rotating the same. The rotary piston of this engine has an imbalance which compensates for the imbalance resulting from the motion of the plate.
