Abstract

596,307. Change-speed gear. GRYLLS, S.H. Jan. 11, 1945, No. 944. [Class 80(ii)] A two-speed gear comprises a friction or positive clutch 3, providing a directdrive between aligned input and output shafts 1, 6; a one-way clutch 10 in one of two countershaft pinions 8, 11 of a reducing-train 7, 8, 11, 12; a second friction or positive clutch 15 for bridging the one-way clutch 10 to transmit engine braketorque in the reduced ratio when required; and a second one-way clutch 16, arranged reversely between the output and input shafts 6, 1 to transmit engine braketorque in the high-ratio when neither clutch 3, 15 is engaged. The clutches 3, 15 may be of the cone, multi- or singleplate, band, or positive-dog type operated mechanically, hydraulically, by pneumatic pressure or suction, or electrically. The gear, two or more of which may be arranged in series on a motor-vehicle, is driven through a centrifugal, or hydraulic clutch or torque-converter 2, which may have an emergency friction or jaw clutch to enable a drive to be transmitted to the engine at speeds below the disengaging speed of the centrifugal or fluid clutch.
