Abstract

793,814. Making commutators. LUCAS (INDUSTRIES), Ltd., J. Aug. 16, 1956 [Aug. 24, 1955], No. 24323/55. Class 83 (2). [Also in Group XXXV] A moulded commutator made by bending a grooved copper strip and subsequently turning off the bridges c between the segments b, is provided with lateral projections e pressed from the side of each segment and serving to key with the moulded insulation. In addition, fangs d at either end are notched at g and bent inwardly to provide additional keying.
