Not illustrated. 1906 edition. Excerpt: ...spring at the moment when the spark is required, and, the spring being fixed at the other end, the break. is very rapid. The whole igniter can be removed from the cylinder for the purpose of inspection by releasing a bayonet joint. For the purpose of obviating any possibility of backfiring when the engine is being started, the armature is automatically adjusted to retard the ignition when the starting handle is introduced. By having the magnets arranged in the fiywheel of the engine, no timing gear is necessary, as the speed of the engine automatically controls the ignition. At low speeds the magnets do not energise the armature so early in the piston stroke, and similarly at high speeds the armature is energised sooner and the spark occurs at an earlier moment. Hion TENSION MAGNETOS.--The systems just described were the only forms of mechanically produced ignition in use until the introduction of the Eisemann high tension system, whose advantages were so great that it leapt into popularity with surprising rapidity. The combination of a self-contained generator used in conjunction with ordinary sparking plugs, thus doing away with the mechanical igniters, was certainly a great advancement, and many designers at once turned their attention to the new ignition, resulting in the appearance of many different forms, each claiming peculiar advantages. High tension magneto systems are divided into two classes. In the one case a low tension generator, having a high tension distributor as an integral part OI it, is employed, and a separate induction coil is made use of for transforming the current, and in the other case the whole system is contained in the one machine, wires being led straight from it to the plugs on theiengine. This system was...
