Abstract

331,396. Duncan, H. L. July 11, 1929. Commutators. - The surfaces of the segments a, Fig. 2, of a dynamo commutator or similar device are caused to stand out beyond the intervening insulating segments b by means of a film of nickel, chromium or other metal c which is deposited electrolytically without the usual step of grooving the insulating segments. In the case of a commutator separated from an armature, all the segments may be bonded together by a wire wrapping, the short-circuited commutator as a whole then being immersed in the plating- bath, but in the case of a mounted commutator, Fig. 3, the armature windings give the requisite connection between the segments which are connected to the battery cathode as shown. The normal insulation between the shaft e and the commutator and windings may prevent deposit on the submerged part of the shaft, or this part may be coated with wax or other protective material.
