Dynamo-electric cycle axle

Claim 1

A dynamo-electric cycle axle for positioning within the hub of a wheel, comprising in combination: (a) an elongated axle cylinder together with a multiplicity of curved permanent magnets longitudinally centered along the inner periphery of said axle cylinder thereby forming a generator rotor; (b) a stator coaxially positioned within said axle cylinder, containing an induction coil set and two threaded axles on either side, wherein said rotor rotates relative to said stator thereby forming a voltage generator; (c) means for conducting electrical energy from said induction coil set to a fixed contact and conductor; (d) two ball bearing assemblies each constructed of a cylindrical inner cup, a multiplicity of ball bearings and a ball retainer, wherein one ball bearing assembly is coaxially placed on each of said axles; (e) two circular rings selectively insertable into each end of said central cylinder at a desired depth to respectively limit the inward ingress of said ball bearing assemblies to a desired depth; (f) lid nuts with inner threads which thread onto mating threads on said axles, wherein said lid nuts secure said ball bearing assemblies in place and wherein said lid nuts are stationary with respect to said axles and movable with respect to said ball bearing assemblies; (g) adjustment nuts integral to said lid nuts and located axially on the outside surface of said lid nuts; (h) two end cylinders placed laterally on either side of said induction set, and a washer disposed between each end cylinder and the adjustment lid nut, the outer diameters of said end cylinders and said washers being less than the inner diameter of said circular rings, whereby adjusting each of said adjustments nuts can axially shift said stator to center said induction coil set with respect to said magnets and also distribute biasing stresses upon said ball bearing assemblies.
