Abstract
555,975. Motor cycles. VINCENT, H. R. D., CO., Ltd., and VINCENT, P. C. Jan. 6, 1942, No. 217. [Classes 79 (ii), 79 (iii), 79 (iv), 79 (v) and 136 (iii)] A motor cycle has either or both wheels each supported by a single longitudinal arm 13 or 14 attached directly to the engine unit 12, the engine unit being sufficiently strong to act as the frame; spring means are provided between said arms or the wheels and the engine unit, or the arms may be formed as springs secured to the engine unit. In the construction shown in Figs. 1, 2, 5 and 8, the arms 13, 14 are pivoted at 23, 28 to the engine unit 12, the front arm 13 is controlled by a torsion spring 15, and the rear arm 14 by a spring 30 housed in a telescopic casing 31, 32. The rear end of the front arm is forked and is pivoted on a sleeve 23 secured by studs 26 to the engine casing 20. The front wheel 10 is mounted on a stub axle having a steering pivot mounted in bearings 39 on .the arm 13, and is steered by means of handlebars 51 on a steering shaft 50 connected by a link 48, bellcrank lever 44, 43 and link 42 and an arm 40 on the stub axle. The rear wheel is driven through bevel gearing from a shaft passing through the arm 14. The vehicle may be provided with one or two seats 70 on a sheetmetal casing 71 carried by a framework (not shown) secured to the engine. The casing is formed with mudguards 74, 75 and leg-shields 73, and carries a windscreen 77 and the headlamp 79. Foot-rests 80 are provided. Either or both of the arms 13, 14 may be rigidly secured to a formed integral with the power unit, spring means being provided between the wheels and the rims. In the case of the front wheel, Fig. 7, the front end of the arm 13 is forked and carries a steering pivot 83 secured by a bolt 84. The wheel spindle 89 rotates in bearings in a hub member 86 which is offset from the pivot 83 and can slide and rotate on the pivot. The vertical movement is controlled by a main spring 94 and a rebound spring 95, and the hub 86 is formed with a steering arm 40 controlled by the handlebars through a link 42 and the steering linkage. Brakes are provided on both wheels. The engine is preferably of the kind described in Specification 555,974, [Group XXVII], and is a twocylinder opposed-piston two-stroke, having transverse cylinders 8 and a pump cylinder 9. Two crankshafts are arranged one at each end of the cylinders and are gear-connected to the shaft driving the rear wheel.
