Figs. 67 and 68, taken together, should give a clearidea of the operation of the valve. An enlarged view of the cylinderand magnet valve in Fig. 68 is given in Fig. 69. Details of the blow-out coil are shown in Fig. 70. The appearance of the switch groupis given in Fig. 7L Control and Motor Circuits. The control and motor circuitsare shown in simplified form in Fig. 72. The main circuits are inthe upper left-hand corner and the control circuits are in the lowerright-hand corner. In the lower left-hand corner is a table showingthe sequence of switches corresponding to the several series andparallel positions.

They may readily be identified by the designatingletters and figures. As the details are the same as in the Sprague-General Electric system, the student will be able to trace out thecircuits without further assistance, referring to the previous explana-tions if necessary. Air Supply. As all cars large enough to warrant tne use of themultiple-unit system are also provided with air brakes, there isample air supply for the control system. This air is drawn from thebrake reservoirs shown dotted in Fig. 73 and flows
