ABSTRACT:
The disclosed friction disc transmission includes a conventional drive disc rotatable about a vertical axis and a vertical friction disc engaging the top horizontal face of the drive disc to be driven about a horizontal axis. The friction disc is rotatably supported on a pivot frame having a sprocket drive connected to a sprocket on the wheel axle. The wheel axle sprocket in the self-energizing transmission is located vertically below the drive sprocket and the drive sprocket is located between the frame pivot axis and the friction disc. The tension in the drive chain thereby compresses the friction disc into engagement with the drive disc in proportion to the torsion in the wheel axle and eliminates the requirement of a spring. Other improvements include the novel chain drive including a driven sprocket on the pivot frame.
