Abstract

860,802. Commutators for dynamo-electric machines. BOSCH G.m.b.H., R. Oct. 20, 1959 [Nov. 6, 1958], No. 35428/59. Class 35. In a commutator in which the V-rings 12, 13 are secured by flanging the ends of the hub 14, the hub tube is provided with shallow peripheral grooves 20, 21 to facilitate the flanging process.
