Abstract: A high ratio drive wherein a housing supports a first fixed annular toothed raceway and rotatably supports a second axially aligned toothed raceway. A coupled pair of axially aligned toothed wheels are disposed within and having rolling contact and tooth interengagement with the toothed raceways, respectively. The housing supports a rotatable output shaft that is secured concentrically to the second toothed wheel. A rotatable drive shaft having drive spokes secured thereto is supported by the housing in axial alignment with the output shaft. The drive spokes contact the bores of roller bearings that are mounted in each toothed wheel. Rotation of the drive shaft will cause the drive spokes to impart a radial drive force to the toothed wheels thereby forcing them to roll on their respective toothed raceways. This transmits differential rotation to the second toothed raceway and output shaft at a high ratio.A modified form of the drive has a toothed wheel eccentrically disposed in a fixed toothed raceway.

Abstract: An infinitely variable speed automatic transmission employs a housing that fixedly supports an annular toothed raceway. A toothed wheel having an inner raceway is disposed within the toothed raceway and has rolling contact and tooth interengagement therewith. The housing supports a rotatable drive shaft that is concentric with the toothed raceway and supports a radially moveable roller bearing. A drive roller engages the roller bearing and the wheel's inner raceway. A stabilizing roller contacts the wheel's inner raceway and is supported by an arm that is secured to an output shaft. The output and input shafts are axially aligned. Rotation of the drive shaft will cause the roller bearing to impart radial driving impulses to the wheel through the drive roller. In turn the wheel transmits planetary rotation to the stabilizing roller, which rotates the output shaft through the connecting arm.The wheel acts as a circular lever with the fulcrum being on the wheel's contact point with the toothed raceway.

Abstract: A flexible coupling having a rotatable drive and driven member. Each member has a pair of diametrically opposed lugs secured thereto. A floating member having four equally spaced peripheral grooves is disposed between the drive and driven member. Tilting elements contact each lug of the drive and driven members with two sides of each respective groove of the floating member.
