Abstract:
A vibrating mechanism comprising:(a) a housing having a lower end and having an interior space, the housing comprising an oblongated downwardly opening cap having a lower lip and an oblongated upwardly opening bowl having an upper lip; the lower lip of the oblongated downwardly opening cap being fitted so that it may be placed in contact with and fixedly attached to the upper lip of the oblongated upwardly opening bowl;(b) a wheel having a plane of rotation extending therethrough; the wheel having an axis of rotation extending axially therethrough, the axis of rotation perpendicularly intersecting the plane of rotation; the wheel having a center of gravity, the center of gravity of the wheel being radially removed from the axis of rotation; the wheel having an outer radial surface; and the wheel having a multiplicity of teeth extending radially outward from its outer radial surface;(c) rotatable mounting and positioning means mounting and positioning the wheel within the interior space of the housing so that the plane of rotation intersects the lower end of the housing; the rotatable mounting and and positioning means comprising a drive axle receiving channel extending axially through the wheel, and a drive axle extending through the drive axle receiving channel, the upper and lower lips of the cap and bowl being fitted for rotatably receiving and retaining the drive axle;(d) means for alternately fixedly attaching the housing to and removing the housing from an earth compacting machine, said means being fixedly attached to the housing; and,(e) a gear, the gear having an axis of rotation and a center of gravity, the center of gravity of the gear being radially removed from the axis of rotation of the gear; the gear being rotatably mounted and positioned within the interior space of the housing so that upon rotation of the wheel, its teeth engage and counter-rotate the gear.
