The inboard type of motor is intended for use where the flywheel is exposed while the outboard form has been designed for attachment to the flywheel case of a power plant having an enclosed flywheel. The two switches are also shown in this illustra Fig. 248.-Two Types of Westinghouse Starting Motors and Operating Switches. tion. The magnetic switch is a simple form operated by a push button. The plunger switch follows the conventional design for devices of this character. The wiring diagram when the plunger switch is used is very simple as outlined at A, Fig. 249. The other circuit at B shows the method of connecting the electro-magnetic starting switch. The application of a Westinghouse generator of the simple form to a 1916 National Twin Six engine is shown at the top of Fig. 250. The method of mounting the starting motor is clearly shown in the top view of the motor at the bottom of the illustration. The Fig. 249.—Wiring Diagram Showing the Use of the Westinghouse Starting Motor with Mechanical Switch at A and with Magnetic Switch and Generator at B. wiring of the Westinghouse lighting circuit is shown at Fig. 251. This does not differ greatly from other one wire systems having a separately mounted current regulator. The complete wiring diagram presented at Fig. 252 is that used on the Pierce-Arrow closed cars and shows all necessary connections as well as the various circuits for a comprehensive starting and lighting system. The various accessory devices comprising the Westinghouse system are built on approved electrical principles. Some of these are shown at Fig. 253. To prevent injury to the battery and lights through short circuits due to accidents or carelessness, fuses should be used in all lighting circuits. The Westinghouse fuse boxes are not only thoroughly enclosed but they are arranged to use enclosed Fig. 250-Views Showing the Practical Application of the Westinghouse Generator and Starting Motor to National Twin Six Engine. fuses which do not produce a spark when they blow. A four-circuit fuse box, as illustrated, is necessary if a dome light or buzzer is used, though a three-circuit fuse box will be adequate in the ordinary open car lighting system. A circuit is usually provided for the head lights, one for the side lights, and an extra circuit for |
