Abstract
Abstract A cage for a roller clutch is formed from a flat stamping having an annular portion with the tab-like projections extending generally radially from the inner and outer edges of the annular portion, the tab-like projections being arranged to permit the stamping of small diameter cages and, when folded, to provide retaining means for the rollers and energizing springs.

Claim 4
Dependent Claim
45 words
A cage for an overrunning roller clutch according to claim 1, characterized in that the energizing springs (3) have tongues (14) on their outer legs (23) of U-shaped ends (13) alligned with inner tabs (8) which lockingly mesh into openings (15) in the lugs (12).
Claim 5
Dependent Claim
28 words
