In this part we give descriptions and illustrations of ordinary styles of legs, such as we have made here—with various modifications and improvements, as suggested by time, wear and experience—for forty-five years. Excepting the Walkeasy leg, described in Part I, there are no better nor more reliable artificial limbs made anywhere by anyone, and the prices are much below those charged by other manufacturers.
The various styles are:
Wooden foot with ball-and-socket ankle joint
and wooden socket.
Wooden foot with ball-and-socket ankle joint and leather lacing socket.
Wooden foot with hinge ankle joint (army and navy or two-ball) and wooden socket.
Wooden foot with hinge ankle joint (army and navy or two-ball) and adjustable leather lacing socket.
Foot with sponge-rubber or felt removable sole and rigid ankle and wooden socket.
Foot with rigid ankle and adjustable leather lacing socket.
The cords and springs used in the legs with
articulated ankle joints are the same as are used in
the Walkeasy leg. The springs are rubber used
by compression, imparting easy, uniform motion,
their power and action being regulated by simply
turning a nut, so that the wearer may adjust them
to suit his own peculiar gait.
In walking, when the weight of the body rests on the ball of the foot, the spring in the back part of the leg (heel spring) is firmly compressed, and when the weight of the body is thrown forward
