APPARATUS FOR EXERCISING THE MUSCLES.

The apparatus herewith illustrated consists of a wooden base, which

may be bolted to the floor, and which supports two wooden uprights, to

which is affixed the apparatus designed to exercise the legs. The

apparatus for exercising the arms is mounted upon a second frame that

slides up and down the wooden supports. It is fixed in position at any

height by means of two screws.

[Illustration: APPARATUS FOR EXERCISING THE MUSCLES.]

The apparatus for exercising the legs, as well as the one for the

arms, consists essentially of a fly wheel mounted upon an axle

extending to the second upright and bent into the form of a crank in

the center. The fly wheel is provided with a winch whose arm is

capable of elongation in order to accommodate it to the reach of the

sound limb.

The apparatus for the legs is arranged in a contrary direction, that

is to say, the wheel is on the opposite side of the frame, and upon

the fixed uprights. It is really a velocipede, one of the pedals of

which is movable upon the winch, and is capable of running from the

axle to the extremity, as in the upper apparatus. This pedal has the

form of a shoe, and is provided with two straps to keep the foot in

place and cause it to follow the pedal in its rotary motion. A movable

seat, capable of rising and descending and moving backward and

forward, according to the leg that needs treatment, is fixed back of

the apparatus.

The operation is as follows: Suppose that the atrophied arm is the

left one. The invalid, facing the apparatus, grasps the movable handle

on the crank with his left hand, and revolves the winch with his

right. The left hand being thus carried along, the arm is submitted to

a motion that obliges it to elongate and contract alternately, and the

result is an extension of the muscles which strengthens them.

The apparatus, which is as simple as it is ingenious, can, it is true,

be applied only when one of the two limbs, arm or leg, is diseased,

the other being always necessary to set the apparatus in motion; but,

even reduced to such conditions, it is destined to render numerous

services in cases of paralysis, atrophy, contusions, etc.--_Moniteur
