Abstract

453,616. Magnets. WATSON, L. T., Ashton, Elmdon Road, Marston Green, Warwickshire. May 10, 1935, No. 13762. [Class 35] Mounting dynamos ; driving-arrangements.- In a cycle-lighting dynamo of the frictionally driven-type in which the rotor consists of a permanent magnet rotating between stationary generating coils, the generating coils are connected separately or in groups so that an independent circuit is obtained for each lamp. The rotor consists of a cylindrical magnet A axially divided in halves separated from each other by non-magnetic material. The two parts are enclosed in an aluminium or other sleeve e and are separated from the spindle by a brass or other bush g. The ends of the rotor, are in magnetic contact with cast iron or steel plates f carrying polepieces f which overhang the sleeve and may occupy recesses therein. The rotor axis may be eccentric to the axis of the stator casing B. As shown, there are four generating coils, and three are connected in series to supply the head lamp and the fourth supplies the tail lamp. The dynamo is mounted above the wheel as shown in Fig. 1 and is pivoted on a spindle p tangential to the casing in such a manner that its weight, assisted by a spring wound on a sleeve surrounding the spindle p maintains the friction roller l in contact with the tyre. A finger operated pawl n is provided to hold the machine in an inoperative position. The friction roller has a milled periphery and is preferably tapered as shown in Fig. 3. A cover n may be provided partially to enclose the roller.
