856,061. Winding coils for dynamo-electric machines. GENERAL ELECTRIC CO. Ltd., DAVIS, L. A., and TOMPSETT, L. C. Dec. 22, 1958 [Dec. 20, 1957], No. 39764/57. Class 35. Stator or rotor slot windings are first wound on to a mandrel comprising four pins 8 and then forced off these into the slots. In one form, Fig. 1, wire 13 is fed in a single or double layer on to the pins by means of a cranked tube 10 carried on a pair of cranks 15, and then, with the pins placed in a position over the slots, an ejector plate 17 descends and forces the wire into the slots. In a modification, Fig. 4, in which the slots to be wound are external, both the core 1 and winding mandrel 7 rotate together about axis 19 in the position shown to wind wire on to pins 8. This wire is then forced off the pins by ejector 17 as before. The slots may be skewed, and the necessary motions of the various parts may be produced manually or automatically.
