  • Patent number: 4473291
    Abstract: In a large, track mounted industrial camera or projector, a leveling arrangement for maintaining the track rails level when their support beams deflect under the influence of the weight of the camera and the rail mounted carriage which carries the camera toward a subject holder at one end of the track. Each rail is mounted on a rail base held down on the underlying support beam by a series of hold down screws. Adjustment screws are threaded through the rail bases and rest on the beams at their lower ends to control the distance of the rail bases above the beams. Each adjustment screw can be independently adjusted to compensate for beam deflection under actual loading conditions and for the variation in beam deflection along the length of the track. The overall track structure is stiffened to reduce beam deflection by an internal cable support structure secured to the rails and by a canopy secured to the beams.

  • Patent number: 4000702
    Abstract: A transportation system includes a pair of rails spaced transversely of an elongated track on which flanged support wheels of a vehicle are adapted for travel along the sides, top or bottom of the track. The support wheels are transversely spaced apart by at least one-half the width or one-half the height of the vehicle and are sloped to respectively lie in planes intersecting at the center of gravity of the vehicle. Accordingly, horizontal forces acting on the vehicle during travel around curves produce no stresses on the wheel flanges but increase direct stress on one set of wheels and decrease direct stress on the other set of wheels.In another embodiment, the wheels are designed to tip parallel to the resultant forces acting on the wheels during horizontal force changes acting on the vehicle.
