Fig. 1 represents a machine, called the Manipulator, which transmits motion through suitable attachments, which are adjustable by means of the ratchet G, so as to reach all parts of the body. It is equally available for applying motion to the head, feet, or any intermediate part of the body.
B, B are rubbing attachments, with two opposing elastic, adherent surfaces, between which an arm or a leg may be included. These have alternate reciprocating action from the rock-shaft H, and are made to approach each other, and press the included part at the will of the patient. This is sometimes called the double-rubber, and is made detachable if desired.
A is the lever, by which the two parts of the double-rubber are made to compress the arm or leg.
D is a single attachment for rubbing. It may be connected at either side of the machine, so as to present the rubbing surface in four different directions, as may be most convenient. It will act perpendicularly, horizontally, or diagonally, and from below or from above the part receiving the action, according to requirements. The shank of the rubber may have any special form to suit special cases.
C is the foot holder. It communicates to the leg the semi-rotary or oscillating motion of the rock-shaft. It may be attached to either end of the rock-shaft.
E is the hand holder, which, grasped by the hand, communicates motion to the arm, shoulder, and chest; or the hand may be inserted passively, when the effect of motion is more confined to the hand and fore-arm.
In the position shown in Fig. 2, by means of the single rubber attachment, the manipulator acts upon the upper portion of the trunk, neck, head, and arms; by means of the hand-holder, upon the arms; by means of the double-rubber, upon the arms, shoulders, and scalp.
