The clutch includes a first sheave secured to a driven shaft, a second sheave on the shaft adjacent the first sheave but rotatable and axially movable relative to the first sheave and to the shaft. The two sheaves form an annular outer space for receiving a driving belt, and an annular inner enclosed , space which receives a cam mechanism and a spring. The cam , mechanism and the spring are connected to the two sheaves and I adjust the width of the annular outer space in response to I various drive conditions.</p> |
