  • Patent number: 4697663
    Abstract: A vehicle with three wheels includes a single rear driven wheel and two front steerable wheels. The front wheels are supported by cross members in a parallelogram mechanism carried by the frame of the vehicle. A platform is connected to the frame and extends rearwardly of the cross members on both sides of the lower cross member. A U-shaped center stand is pivotally connected to the platform an axis extending perpendicularly to the longitudinal axis of the vehicle. The center stand in its deployed supporting position also engages the vehicle frame for keeping the vehicle upright.

  • Patent number: 4378133
    Abstract: This invention involves a filament wound composite core which is combined with one or more additional cores to produce a loop track characterized by transverse curvature and stud bands extending between the sandwiched or laminated cores and which extend to provide sprocket engagement for transferring motive power to the loop track, and a system for mounting the novel loop track on a vehicle.

  • Patent number: 4270811
    Abstract: A vehicle supporting endless traction band including an endless resilient band of concavo-convex transverse shape and a pair of assemblies for supporting and protecting opposite sides of the band. The assemblies are similar to conventional roller chains except that the inner support links (those adjacent the sides of the band) are configured to pivot on the chain studs and to define slots into which the side margins of the band are received. A plurality of tension resistant members obliquely span the space between the roller chain assemblies on the concave side of the band to prevent the band from buckling when subjected to concentrated loads.

  • Patent number: 4088199
    Abstract: A three-wheeled motorcycle in which two front wheels are interconnected with a conventional motorcycle frame by a parallelogram configured coupling assembly utilizing a pair of cross members pivotally connecting hubs of the front wheels and pivotally connected to the frame. Foot resting platforms are positioned on either side of the motorcycle, being fixedly connected to one of the cross members in the front which is pivotally connected to the motorcycle frame.
