Abstract

12,774. McLean, M. A. May 29. Brush-holders.-A brush 4 sliding in a holder 1, 3 is pressed against the commutator by a spring 5 through a plunger 9 and a spring plate 12, the spring 5 being contained in a tube 7 inserted in a slot 8 in the holder behind the brush, and provided with a number of notches 13 adapted to engage with a spring catch 14, the tension of the spring 5 being adjustable by means of a nut 15 and a screw 17. A nut or washer 20 is firmly attached to the upper end of the rod 17 under the cap 19 and is provided on its upper surface with a projection 21 adapted to engage with one or other of several grooves or notches in the cap 19.
