Abstract
495,813. Magnetos. BOHLI, J. May 27, 1937, No. 14703. Convention date, May 27, 1936. [Class 351 The field magnet of a magneto consists of several bipolar tubular permanent magnets arranged parallel to each other and to the machine axis, the magnets which have the poles on their cylindrical surfaces being pressed into contact with soft - iron pole - pieces. As shown applied to a rotor, Fig. 1, the magnets 10 are arranged with like poles facing each other, and between them are disposed laminated or solid pole-pieces 9. Non-magnetic discs 15 carried on a shaft bushing 15<1> and perforated to receive the magnets are spaced throughout the length of the core and to them are riveted the pole-pieces. In a modification, Fig. 3, the magnets 10 are disposed between a grooved soft-iron tube 12 and the pole-pieces 11, and are supported by non-magnetic discs 13 having a central hole large enough to admit the tube 12. If discs similar to the discs 15 are employed, the tube 12 must be subdivided axially and screwed or riveted to the discs. Stops are provided to prevent rotation of the magnets. The Specification as open to inspection under Sect. 91 comprises also the following : A single six-pole tubular magnet 3, Fig. 1 (Cancelled), carried by a non-magnetic cylinder on the shaft has shrunk on it a frame comprising laminated pole-pieces 5 joined together by non-magnetic rings 4. The pole-pieces may be dispensed with. In the case of a stator, a similar magnet is shrunk on to a pole-piece assembly. The magnets may be solid cylinders or may be of other forms. This subject-matter does not appear in the Specification as accepted.
