This brake is operated by simply reversing thecontroller handle beyond the zero companys controllers are supplied with solenoid spark blowouts. Arcing in the controller is in this way positively pre-vented, the sparks being blown out radially from the controllerspindle. The Walker controller has seven positions for directoperation, and about four for braking. In positions 1 to 3 themotors are in series with a rheostat in the circuit; in 4, the motorsrun in series without the resistance; in 5 and 6, the motors are inparallel with each other, and in series with the rheostat; in 7, theyare parallel with the resistance cut out. The rheostats are madeup of iron strips wound spirally on a cast frame, the windingsbeing insulated from each other by asbestos.
