ABSTRACT:
A sprag clutch utilizing the principles of U.S. Pat. No. 3,651,908 has an improved energizing spring arrangement in which the individual sprag energizing springs are mounted on intermediate portions of bars forming part of the sprag retainer assemblage. The retainer is made in two identical annular parts which clip together. The bars define with end rings parts of the retainer, separate compartments, one for the outer end of each sprag, end portions of the bars acting to position the sprags circumferentially, and the energizing springs extend inwardly from the bars. The arrangement facilitates the manufacture and assembling of the assemblage and allows more sprags to be accommodated in a given diameter. [and, conveniently, the retainer is made in two identical annular parts which clip together.]
