Abstract
Abstract The rocker of the present invention includes rocker bars which are operatively connected to a base to permit controlled rocking movement of the rocker on the base, and automatic rocking means operatively associated with at least one of the rocker bars for rocking the same. The automatic rocking means comprises an electric motor and a crank rotatably driven by the motor, such crank being engageable with the adjacently disposed rocker bar for lifting the same for a relatively limited period in the rotational cycle of the crank, and the rocker bar being free to rock by itself when out of contact with the crank.
