506,298. Motor wheels. FICHTEL & SACHS AKT.-GES. Feb. 17, 1938, Nos. 4991 and 4992. Convention dates, Feb. 17, 1937 and Feb. 19, 1937. [Class 79 (iii)] A motor wheel comprises a cup-shaped casing 3 secured to the wheel hub and forming the centre of the wheel, such casing accommodating the change-speed gear and clutch, the engine cylinder 8 and crank case being partially accommodated in the lower portion of the casing with the greater portion of the cylinder projecting laterally outside, the carburetter in the upper portion of the casing, whilst the exhaust pipe 9 and the flywheel 7 with the generator lie outside the casing. The projecting portion of the cylinder has cooling ribs parallel to the direction of travel, and inclined downwardly to avoid accumulation of dirt. The upper portion of the casing is closed by a stationary cover 4 having an aperture 6 through which an auxiliary fuel-injection pump on the carburetter is accessible. The engine cylinder 8 and crank case are integral with an inner casing enclosing the change-speed gear and clutch. This casing is freely mounted on the hub but is resiliently restrained against rotation.
