Abstract
A clutch for engaging a driving member with a driven member automatically upon application of torque to rotate the driving member in either direction, for maintaining engagement in either the drive or coast mode of operation and during the transition between drive and coast, for maintaining engagement in either forward or reverse operation and during the transition between forward and reverse, and for disengaging automatically upon interruption of the torque and slight relative rotation of the members. The clutch includes a mechanism for developing high frictional drag upon initial rotation of the driving member to effect engagement, and low frictional drag thereafter to conserve power. The clutch also includes a preloading mechanism so that if engagement should be blocked, it will be completed automatically when the blockage is relieved. The clutch further includes a mechanism tending to resist initial rotation of the driving member so that a false torque signal does not cause engagement.
