Abstract
. 615,670. One-way clutches. GEAR GRINDING MACHINE CO. April 29, 1946, No. 12916. Convention date, July 2, 1945. [Class 80 (ii)] [Also in Group V] In a one-way clutch having coaxial concentric driving and driven members, a series of spaced sprags is secured to rubber-like resilient means to form an annulus insertable between the spaced concentric surfaces. The sprags A which have arcuate end surfaces A<1>, A2 concentric with spaced centres A3, A<4> are held in radially aligned notches F<1>, GI in a mould F, G which is filled with the green material for neoprene and is then cured in a hydraulic press. The resultant annular unit is then inserted between the spaced concentric members C, D to form the clutch, the length of the sprags A being slightly longer than the width between the members such that the initial inclination of 9 degrees of the sprags is reduced to 4 degrees to bias the sprags to provide initial friction to assist braking in one direction. In modifications, the rubber-like material may be of completely annular form and vulcanized in channels formed in the ends of the sprags, or the sprags may be vulcanized into a straight rubber-like strip which is bent into an annulus on assembly of the clutch.
