Abstract

19,010. Walker, M. Aug. 23. Commutators of the type described in Specification No. 5450, A.D. 1906, having flanged or grooved bearing- surfaces for the collecting -brushes, are built up of sections 1, 2, Fig. 1, placed end to end, each section comprising a number of commutator segments forming one or more flanges or grooves. Each section is held in position by rings 5, 6 which enter notches in the sides thereof and are connected together by bolts 8. Each segment of the section 1 is provided with a lug 14 having a forked extremity, into which enters the extremity of a corresponding lug 17 attached to the opposite segment of the other section of the commutator ; the two lugs may be joined by soldering. The securing-rings 5, 6 between adjacent sections may be replaced by a single ring. The lugs 14, 17 may be wedge-shaped, so that, when the sections are built up on the shaft, they engage with one another to provide a good contact. The mica or other insulating-material separating the segments of each section may be interleaved with that of adjacent sections so as to prevent the lugs of one section of the commutator from making contact with one another.
