From the collection of automobile parts and servicing equipment acquired by Mr. T.H. Oliver, father of donor, during his career in automotive serving. He worked at Willys-Olivand, Fairbanks-Morse in Toronto and an auto garage in Aurora. In 1931, he began his own business, one part of which involved automotive electrical servicing.

Fonction

Part of an ignition system of internal combustion engine. It uses a magnetic field to produce an electric spark, which explodes gasoline vapour in a cylinder of engine, enabling it to function.

Technique

One example of a magneto produced by a small number of relatively short lived manufacturers in the early electric auto ignition field. It exhibits relatively crude construction characteristics of new manufacturers, lacking research and development experience but the zinc alloy body is still in good condition (REF. 1). The magneto ignition system was a technological innovation first developed in 1878 by Nikolaus August Otto, which was based on the principle of Siemens' double-T armature (Diesel, Goldbeck, and Schildberger: 64). The development of electromagnetism in the 19th century greatly influenced the advancement of magnetos by various inventors around the world. As the automotive industry grew, the magneto ignition system became the standard automotive ignition system, resulting in the wide spread use of magnetos on early engines (Bosch. "Bosch Product History"). Today, automobiles rely on battery power; however, magnetos are commonly used to power small machines, including lawn mowers or snow blowers, and may be found in small gasoline engines such as motorcycles, tractors, marine, and aircraft engines because they do not need a battery ("Magneto").
