ABSTRACT:
A drive mechanism for a body utilizing a motor which rotates a shaft. An eccentric weight is mounted on the shaft for movement with the same. The eccentric weight is linked to a base weight and transmits an oscillational motion along a dimension of the base weight. A torsion spring fixed to the counter weight extends away from the base weight and connects to the body to impart an oscillational torsional motion thereto.
