Abstract
517,576. Commutators for dynamo electric machines ; moulding commutators. HOOVER, Ltd. July 29, 1938, No. 22682. Convention date, Aug. 21, 1937. [Class 35] [Also in Group V] A commutator is constructed by supporting a number of segments 13 in a mould so that their brush-engaging surfaces rest in slots formed in the circumferential wall of the mould and projections 15' on the inner ends of the segment engage recesses in the base 23 of the mould, and injecting a thermo-plastic or thermo-setting compound to form the hub 10 and to embed the segments therein. The apparatus consists of a support 18 having a central cylindrical cavity to receive the mould 22 and base 23, the base carrying a central pin 26 slotted to form. a key on the hub. Above the mould is a stock member 33 with a chamber 39 to receive the moulding material which material is forced through a port 40 into the mould by a plunger 42. Guide pins 20, 43 to maintain the parts in alignment and ejector pins 19, 29 are provided. In the completed commutator, the segments project beyond the insulation and the end of the hub is bevelled. The ends of the projections 15 on' the segments serve for connection to the armature winding; but they may be removed, in which case the leads from the winding are secured in slots cut in the segments.
