<p>A battery-operated electric motor for moving the legs (7) of a walking doll is controlled by a switch (not shown) mounted in the head (9) of the doll and operable to close the motor circuit when the arm (8) of the doll is raised and is operable by a gravity responsive counterweight to open the circuit when the doll falls or takes up a supine position. The motor drive is through reduction gears to two offset eccentrics, which act through links to pivot the legs about a horizontal transverse axis, Figures 1 and 2 (not shown). <IMAGE></p> |
