Abstract

198,725. Hollister, F. L., and Vandervell & Co., Ltd., C. A. Feb. 2, 1922. Magneto-electric machines.-In a magneto having either a bar magnet revolving within a stationary armature or stationary magnet within a revolving armature, the length of the flux path between the poles of the magnet is not greater than the inner diameter of the armature. Figs 1, 2 show a laminated armature a carrying ignition windings d and a revolving bar magnet e flattened in the axial direction of the magneto. The spindle j carries a plate l having flanges p engaging the pole surfaces of the magnet e which is secured to the plate by the stirrup n to which is attached a member q carrying the contact-breaker cam r. The armature and contact-breaker are secured to an end plate f which is rotatably adjustable for timing. In a modification, an adjustable sleeve may be provided between the armature and magnet to adjust the timing. Fig. 6 shows a modification in which two curved magnets e interconnected by laminated pole-pieces e<1> are used.
