Abstract
Abstract A baby crib or cradle adapted to be rocked automatically by an oxcillatory, action motor having the same effect as would be achieved by a mother rocking a crib containing an infant, the crib being pivotally supported at each end thereof to a support rack and stand. The lower portion or bottom of the crib is adapted to be operably connected to the motor. The motor also includes a regulating, reciprocating means for imparting the actuating movement of the crib in a smooth-rocking motion.
