Abstract

533,328. Slotting commutators. GLOBE, R. C. Oct. 28, 1939, No. 28892. [Class 145 (i)] A machine for undercutting the mica insulation between the segments of a commutator consists of a bed having supporting bearings B, B<SP>1</SP> for carrying the armature with its commutator U, and a milling cutter P driven through a belt by an electric motor Q and mounted on a vertically-adjustable slide K itself mounted, for traversing the commutator, on a horizontally adjustable slide G. The motor may be mounted on the slide K and carry the cutter directly on its shaft.
