Cobb invents a walking structure that simulates the action of natural walking using mechanical means, typically for a person who has lost the use of their legs. Motive power is supplied by the operators arms driving a crank-wheel which in turn drives the legs in an oscillatory motion. The same principles as applied to a doll are also described, but is powered by a clockwork motor.
