Period

c. 1910

Canada

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.

Function

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.

Technical

This magneto represents early U.S. development with a robust heavy cast brass design. Similar in concept to a type L International Harvester magneto (970548-970549). Accurate Engineering was a small U.S. manufacturer, which still used heavy and costly brass construction at a time when non-ferrous alloys were being introduced by competitors (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").
