Abstract
Abstract An adjustable torque limiting coupling including a driving member, a driven member, an intermediate member and a housing for the driving, driven and intermediate members. The intermediate member is coupled with the driven member so as to accommodate relative axial motion and prevent relative rotation between the driven member and the intermediate member. The intermediate member includes a disc like portion having a plurality of pairs of radially disposed, diametrically opposed recesses in the face of the disc like portion for engaging in yieldable driving relationship a member projecting from the driving member. Adjustable spring means is provided for urging the recesses and projecting member into yieldable driving relationship, and means for adjusting the spring means andlocking the adjustment of the spring means is provided.
