Abstract
Abstract A compactor base is provided and includes a pair of horizontal eccentric shafts journaled therefrom with the shafts paralleling each other and spaced horizontally apart longitudinally of the base. The shafts are provided with matching meshed gear wheels and the gear wheels are keyed to the shafts by means of oppositely convoluted grooves formed in the shafts and key elements carried by the gear wheels slidable in the grooves. The gear wheels are embraced by thrust bearing equipped yoke structure and the yoke structure is supported from the base for shifting axially of the shafts, the latter being provided with eccentrically disposed weights. By this construction the angular displacement of the eccentric weights relative to the axes of rotation of the corresponding shafts may be inversely varied in response to shifting of the yoke structure longitudinally of the shafts and the compactor base will move forward, rearward or merely vibrate in a vertical plane at the discretion of the operator in accordance with the positioning of the yoke axially along the eccentric shafts.
