1920 International Type M 1 1/2 HP Engine

 This engine (serial #A53073) was made by International Harvester Company at its factory in Chicago, Illinois. Like the McCormick-Deering engines here in this exhibit, also made by IHC, this engine is a Type M, IHC's most widely sold engine on the market. From 1917 to 1937, IHC made 429,376 Type M engines in a variety of sizes, including 1 1/2, 3, 6, and 10 HP.

 If you look on the side of this engine, you might see that it has an IHC Type L magneto for its ignition. This magneto has a patent date of January 30, 1917, which may correspond to one or both patents for magnetos issued to Robert C. Danly on that day. The first of those patents is 1214014, which you can view as a pdf here. The second is 1214015, which you can view as a pdf here.
 The maker of this engine and its magneto, International Harvester Company, was formed when an agreement was made on August 12, 1902 between people representing five different firms that specialized in harvesting equipment. Those firms were the McCormick Harvesting Machine Company; the Deering Harvester Company; the Plano Harvester Company; the Warder, Bushnell & Glessner Company; and the Milwaukee Harvester Company. As you walk around Stuhr Museum's exhibit, you will see several items made by International Harvester, including four engines.
