Abstract
188,643. Bosch Akt.-Ges., R. Nov. 11, 1921, [Convention date]. Magneto - electric machines; magnets. - In a bell-shaped magnet for a magneto, the connection between the magnet bars and yoke piece is made by means of projections on the yoke flanged over into recesses formed in the magnets. As shown in Fig. 1, the magnet bars a, b of curved cross-section are recessed at c, d and a soft iron yoke e is pressed into the, recess c, the magnets being also spaced at the other end by a non-magnetic yoke g which is pressed into the recess d. Peripheral movement of the bars. is prevented by a portion of the yokes being pressed into the space between the longitudinal surfaces of the bars. The yoke e may serve as a bearing for the armature shaft and the remaining parts of the machine may be attached to the soft yokes. Pole-pieces k, Fig. 3, may be attached to a non- magnetic ring i which is secured between the member g and the ends of the magnets. The Specification, as open for inspection under Sect. 91 (3) (a) describes also a connection between the yoke pieces and bars in which any suitable projecting member on the yoke engages a suitable recess in the bars. This subject-matter does not appear in the Specification as accepted.
