Abstract

936,954. Friction brakes. FROMSPRAG CO. Jan. 22, 1960 [Feb. 27, 1959], No. 2429/60. Class 103 (1). A bi-directional torque transmission device with means preventing reaction in either direction of a driven member, such as a shaft 65, on a drilling member, such as a gear 70 journalled thereon, for the controls of aircraft or missile rudders &c., bulldozer or grader scraper blades, automotive steering, or hoists, comprises oppositely directed sets of sprags 82 which are pivotally socketed in an inner member 75 keyed on the shaft 65 and are urged by a garter spring 93 to wedgingly engage a fixed outer race 80 for said prevention of driven member reaction, and on rotation in either direction of the driving member axially extending fingers 85 thereon first take up slight lost motion to release the wedging set of sprags by engaging the outer sprag portions 94 and then take up the remaining lost-motion to drive the inner and driven members through the socketed portions 91 of the released sprags. The sockets in the inner member are suitably shaped to prevent the sprags from leaving their sockets under driving or centrifugal force.
