Abstract

199,424. Hollister, F. L., and Vandervell & Co., Ltd., C. A. Feb. 20, 1922. Magneto-electric machines.-A magneto is provided with an armature having coplanar poles and a field magnet rotating within the armature comprising a pair of bar magnets or a magnet of U- shaped form of steel of high coercive force so arranged that the flux through the armature is quickly reversed. Fig. 1 shows bar magnets a<1>, a<2> and a stationary armature c having poles d, f. In the modification shown in Fig. 2, laminated polar extensions g<1>, g<2> are provided on the bar magnets and the armature pole f is sub-divided into three smaller surfaces f<1> - - f<3>. The pole d carrying the ignition coil e may be provided with a pole-shoe extending over an angle of less than 90‹. The armature in a modification has two small poles each carrying ignition windings and arranged in V-form.
