Abstract

15,686. Churchward, A. Aug. 2. Brushes and b ru s h - holders.- The brush a, preferably of carbon, is mounted in a holder b so as to be capable of longitudinal movement therein, and is pressed against the commutator by a spring n surrounding its stem and capable of being adjusted by a yoke m having a tubular enlargement p, movable longitudinally upon a screwed rod q by means of a nut v. Rotation of the sleeve p is prevented by a key engaging a keyway in the screw q, and the adjustment is maintained by causing the said key to enter a recess formed in the nut v. The screw q has an unthreaded extension, which is secured by a screw n in a socket t formed on the brush-holder. By these means the brush can be readily removed from its holder without disturbing the adjustment of the spring. The main terminal wire is secured to the holder at i. To afford good connection between the terminal and the brush, an auxiliary conductor w is connected on the one hand with the brush stem and on the other with the screw q.
