Doll with roller skates - has legs moved forward alternately by cam with eccentric moving lever connected to axle on which head oscillates

摘要

The skating doll has a motor (2) joined, by gears (3), to a cam (4) to which levers (6) joined to each leg (8) are connected. The doll's feet are joined to roller skates and the legs are moved alternately. The cam has an eccentric (11) which moves in the forked extremity (12) of a vertical lever (13). It's other extremity (15), also forked, moves on axle (16) joined to a bar (17) that is a radial extension of a horizontal sleeve (18). The head (19) oscillates laterally on an axle (20) through the sleeve and it's movement is synchronised, by the lever, with the movement of the legs.
