  • Patent number: 4721100
    Abstract: A massaging machine comprises a roller brush having a plurality of radially extending flexible fingers thereon, the brush rotating about a horizontal axis so that the fingers massage a person lying below the brush. The brush is slidable horizontally on a cantilevered frame which is swingable about a horizontal axis and is counterweighted, the position of the counterweight being adjustable so as to adjust the pressure with which the fingers of the roller brush contact the user. The brush is bodily slidable along the horizontal frame, and a counterweight is automatically slidable in the opposite direction as the brush, to maintain constant the pressure of the brush on the user. The fingers of the brush are releasably retained by a horizontal member, immediately before they contact the user, so that the fingers are bent back and then snap against the user.

  • Patent number: 4711229
    Abstract: A massaging machine promotes circulation in the lower extremities of the body of a user. It comprises massaging components formed as a pair of hollow semi-cylindrical concave dishes, which are driven by an electric motor in pivotal and oscillatory motion relative to a fixed base frame. A mounting plate is displaceable relative to the base frame and can be set in horizontal oscillations by way of a motor-driven single cam and return spring component moving along the longitudinal axis of the massaging components. An arcuate array of cylindrical bearings support each massage component, which in turn is rigidly attached to a lever arm protruding downwards. The lever arms are set in motion to carry out oscillations by way of a motor-driven double cam via rods and return springs. By way of this mechanical arrangement the massaging operation in two directions at once is achieved as in the case of manual massage.
