Abstract
Abstract A mechanical doll is disclosed, whose arms and legs simulate the crawl stroke and flutter kick used by a person swimming in the water. Each arm of the doll has relatively articulated upper and lower portions, and while the legs kick in opposite phase to the arms on alternate sides of the doll, reciprocable operating means not only rotate the arms in opposite alternate directions in relation to the trunk of the doll, after intervening periods of lost motion with respect thereto; but also, during such periods, rotate the lower arm portions in opposite alternate directions in relation to the upper arm portions. In addition, means interconnect the upper and lower arm portions of each arm for conjoint rotation when the arm undergoes rotation in relation to the trunk of the doll.
