Abstract

832,154. Commutators for dynamo-electric machines. BOSCH G.m.b.H., R. Aug. 8, 1958 [Aug. 9, 1957], No. 25474/58. Class 35. The segments 11 of a long moulded commutator are secured by pairs of claws 14, 15; 16, 17; and 18, 19 gouged in succession out of steps 23, 24, 25 on the inner face of the segments. Saw-cuts 35, 36, 37 piercing bridges 22 between the segments allow escape of air during moulding, these bridges being turned off after moulding in the usual way.
