Abstract
7806. Soc. Mimard Blachon et Cie. Aug. 24, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Driving-mechanism, change-speed, for bicycles &c. A chain-wheel A is mounted on the crank axle, and two sprocket-wheels B, D of different sizes are mounted on the wheel axle so as to drive in a forward direction only. An endless chain E passes around the wheels A, B, D, as shown, and also around a wheel C, adjustably-mounted so as to regulate the tension of the chain. Upon pedalling in the forward direction, the wheel B drives the road wheel, and, upon pedalling in a reverse direction, the wheel D drives the road wheel. In the arrangement shown in Fig. 3, a wheel F is carried by the wheel axle, and twu wheels G, H are mounted on the crank axle to clutch the same when pedalling in the forward and reverse directions respectively. The chain E passes around the wheels F, G, H and around a tension pulley C. According to the direction of pedalling, one of the wheels G, H acts as the driver, and serves to rotate the wheel F in a forward direction. Th position of the wheel C can be altered.
