Abstract

586,372. Motor-cycle telescopic front forks. ENFIELD CYCLE CO., Ltd., and GUISE, H. T. Nov. 7, 1944, No. 21804. [Class 136. (iii)] [Also in Group XXXII] A telescopic spring fork for motor-cycles comprises a lower tube e adapted to slide in relation to an upper tube a associated with the steering head b. a rod d, in the tube e having a tapered formation and being slidable relatively to an annulus a<4> on the tube a, a coiled compression spring c being fastened within the upper end of the tube a at one end and to the upper end of the rod d at its other end, and the annulus a<4> and rod d or part thereof being immersed in oil. Oil is introduced through a removable plug a<9> at the top of the tube a and enters the tube e via a non-return valve d' in the piston a<2>, the level being pre-determined by a vent d<1> in the rod d leading to a plug controlled vent d<3>. Air may pass into or from the tube a by means of a gauze filter a<5> within the plug a<9> and an orifice a<6> in the latter. - Phosphor bronze bushes e<4> limit friction between the tubes a, e.
