Not illustrated. 1913 edition. Excerpt: ...running it drives the generator in the usual manner and the motor and gear reduction are at rest, there being no contact or friction in the clutch when the electric motor is standing still. On the other hand, when the gasoline engine is at rest and the electric motor is started, the clutch immediately engages and the electric.motor starts the engine through the medium of the drive which ordinarily, runs the generator. Both the motor and the generator have the highest possible efficiency. The generator is designed to deliver a charging current at low speed and the motor to have a very high initial and running torque. The gear reduction is claimed to be the most efficient type possible. In starting it is not necessary to engage any gears or do anything other than turn the current into the starting motor. When the engine is running and driving the car, the motor and all gears are at rest, so that less power is required to drive the unit than in the case of dynamotors, where the entire starting unit with both sets of brushes and the large armature must be driven continuously. None of the numerous rods or levers used with separate units are necessary. The entire system operates at six volts. The shafts of both machines, of high carbon steel, are particularly heavy and strong. Large annular bearings are used throughout. The machines are rectangular in shape, very narrow in width, 4%"; height, 7%." The control of the output of the generator is inherent in the auxiliary apparatus, being used to control the charging current. The machines are arranged so that brushes can be mounted on either side, making them always accessible to the operator. The wiring scheme is extremely simple, using the grounded return. Effect of back-fire, none. Normal...show more
