Fig. 62. HINea POINT OF ARM Diagram of Sprafrue-GeneralElectric Interlock 155 60 ELECTRIC RAILWAYS there is a switch opened by a spring, the contacts being located in ablow-out field. The switch is held closed by a trigger which is trippedby a solenoid carrying all or part of the line current. The circuitbreaker may be closed by hand. In the car circuit breaker showndiagrammatically in Fig. 58, the setting of the switch is done bymeans of a solenoid, represented vertically. The breaker may betripped either by the heavy-wire horizontal coil in the main circuit, orby the fine-wire horizontal coil in the control circuit. The left-handheavy-wire horizontal coil furnishes the magnetic blow-out field.Reverser. The place of the reversing cylinder of the manualcontroller is taken by a device known as the reverser, Fig. 63, which

Fig. 63. Front and Back View of Spragiie-General Electric Reverser operates on exactly the same principle. The difference is that,whereas the cylinder-is rotated by hand, this one is rocked by twosolenoids, one acting in each direction. Master Controller. The current for operating the contactorscomes from the trolley ware and is distributed to the several solenoidsat the proper instants through a master controller similar fo thatillustrated in Fig. 64. This contains a drum similar in constructionto the main drum of a cylinder controller, but much smaller in diameteras the currents to be carried are small. The segments and contactfingers are of the standard form. This master controller operatesthe contactors and the reversers. Train Line. The control current is carried in a bundle of wiresor cables known as the train line because it passes from one motor 156 ELECTRIC RAILWAYS Gl car to another, connecting all of the switch groups or sets of contactorsin the train. The train line termin
