Abstract
An overrunning roller clutch with a double row of rollers has an increased load bearing capacity, substantially equivalent to that of a clutch having a single row of rollers of double the length, but without the end loading problems that could occur from single, longer rollers. The clutch uses specially designed unitary energizing springs with resilient elements located by a base of the spring, in cooperation with the cage, so as to act independently on each roller of each pair.
