Abstract
The mechanism, designed especially for use in an earth compacting drum, comprises a pair of concentrically-arranged, eccentrically-weighted elements, which are rotated in unison by means of a hydraulic motor. The mechanism is housed within an earth compacting drum, and the one eccentrically-weighted element is translatable, axially, and disengageable from a splined coupling, in order that it may be indexed to different rotary positions relative to the other eccentrically-weighted element. In this manner, vibratory amplitudes may be increased or decreased.
