Abstract
A safety overload clutch wherein the driving and driven members are retained in driving relation by a primary roller on one of the members urged radially into a groove on the other member by an elastic flexure ring loaded by one or more secondary rollers on the one member positioned substantially diametrically opposite the primary roller. When the load on the driven member exceeds a predetermined value, the primary roller rolls out of its groove causing additional deflection of the flexure ring.
