  • Patent number: 5161522
    Abstract: A swing which allows neuromuscular handicapped persons to assume a normal sitting position and to receive good vestibular therapy. The swing has a chair formed by a rigid shell equipped with cushions. The chair is suspended on four ropes which attach to the top edge of the chair back and to the front edges of its sides. The ropes attach at their top ends to a swivel hook mounted on the ceiling or another overhead support. Adjustable head support pads on the back of the chair keep the neck of the occupant from bending unduly and hold the head in place. An adjustable leg support pad on the seat is straddled by the legs of the occupant.

  • Patent number: 4831752
    Abstract: A mounting arrangement for the control switches that control the height and angle of a vehicle mounted snowplow blade. A bracket on which the switches are mounted is attached to the gearshift lever of the vehicle so that the switches are conveniently accessible to the driver of the vehicle. The bracket has a main plate on which the switches are mounted and a flange which is connected to the shift lever by an angle member on the flange and an opposing U-bolt. By tightening nuts on the U-bolt legs, the bracket is rigidly clamped on the shift lever. The angle member resists twisting of the bracket.
