Abstract
145,909. Chitty, H. April 22, 1919. Commutators of the radial type are composed of radial segments a, each of which has, a foot of dovetail form whereby it is secured between clamps c, d, the face a<2> of the commutator being the brush-contact surface, and the surface a<3> being provided with projections for connexion to the armature conductors b. and spaces are left between the segments, as described in Specification 121,320, for the passage of cooling-air.
