Abstract

584,867. Making commutators. HOOVER, Ltd., and DIMMOCK, W. J. T. Sept. 15, 1944, No. 17673. [Class 83 (i)] [Also in Group XXXV] In commutators formed from a strip bent into a ring and slotted to provide a series of tongues which are embedded in a mass of moulded insulating material prior to the ring being cut into separate segments, the tongues have slots for the entry of moulding material to assist in fixing the segments. In the form shown a strip A is first slotted at A', and the slot openings partially or completely closed as by punching at A<2>, Fig. 2, and then slots are cut leaving the tongues A‹, Fig. 3. The strip is then bent into a ring, and the tongues are embedded in the moulded insulation. Figs. 5 to 8 (not shown) illustrate a process in which tongues are formed within a tube as by broaching and transverse slots are cut and partly or completely closed as before.
