ABSTRACT:
The present invention provides an infinitely variable rotary drive transmission having an input member and an output member rotatably mounted to a housing. A slide is linearly reciprocally mounted to the housing in a direction substantially radial with respect to the axis of the input member. The input member rotatably drives an articulated shaft which is connected to the slide by rods so that the input member reciprocally linearly drives the slide. The slide in turn is connected to and rotatably drives the output member through a pair of cooperating clutch assemblies. A bottle screw varies the degree of articulation of the articulated shaft which, in turn, varies the stroke of the slide per revolution of the input shaft to thereby vary the rotational speed of the output member. A shift assembly is operable to reverse the direction of rotation of the output member as desired.
