A continuously variable power transmission including a driving pulley and a driven pulley that each include a fixed face and a movable face, the movable face being movable in a direction toward and away from the fixed face to vary the effective driving radius of the respective pulleys and thereby vary the drive ratio. The movable face of the driving pulley is actuated by a centrifugal weight assembly including a primary weight and a secondary weight each mounted on a common pivot axis. The primary and secondary weights are adapted to rotate together duri...


A drive pulley for a belt-type, variable speed power transmission, said drive pulley comprising: a. a drive shaft adapted for connection with a source of rotational power; b. a first pulley wall coaxial with and drivingly connected with the drive shaft to rotate therewith, the first pulley wall including a first pulley surface inclined to the drive shaft axis for drivingly engaging a first side of a drive belt; c. A second pulley wall adjacent to and coaxial with the first pulley wall and movable axially along the drive shaft axis toward and away from th...
