ABSTRACT:
This invention relates to friction drive transmissions of the variable or infinite ratio type, having two oppositely tapered shafts, bearing mounted and housed in the same plane and equally spaced apart along their length. A vertical and horizontally mobile rack is mounted between the shafts in a plane parallel but perpendicular to theirs. On the said rack are journaled two intermediary wheels so mounted as to synchronously rotate, slide and cant while one or the other of the intermediary wheels is in contact with the said shafts. Two more intermediary wheels are so mounted as to provide reverse rotation of the output shaft.
