Young Brunette Girl Loves The Winter And Snowmobiles
|
The relatively dry snow conditions of the United States Midwest suited the converted model Ts and other like vehicles but they were not suitable for operation in more humid snow areas such as Southern Quebec and New England. This led Joseph-Armand Bombardier of the small town of Valcourt in Quebec, Canada, to invent a different caterpillar track system suitable for all kinds of snow conditions. Bombardier had already made some "metal" tracked vehicles since 1928, but his new revolutionary track traction system (a toothed wheel covered in rubber, and a rubber and cotton track that wraps around the back wheels) was his first major invention. He started production of a large, enclosed, seven-passenger snowmobile in 1937, the B-7 and introduced another enclosed twelve-passenger model, the B-12 in 1942. The B-7 had a V-8 flathead engine from Ford Motor Company. The B-12 had a flathead in line six cylinder engine from Chrysler industrial, and 2,817 units were produced until 1951. It was used in many applications, such as ambulances, Canada Post vehicles, winter "school buses", forestry machines and even army vehicles in World War II. Bombardier had always dreamed of a smaller version, more like the size of a motor scooter.
• Individual snowmobiles
Numerous people had ideas for a smaller personal snowmobile. In 1914, O.M. Erickson and Art Olsen of the P.N. Bushnell company in Aberdeen, South Dakota built an open two-seater "motor-bob" out of an Indian motorcycle modified with a cowl-cover, side by side seating, and a set of sled-runners fore and aft. While it did not have the tracks of a true snowmobile, its appearance was otherwise similar to the modern version and is one of the earliest examples of a personal motorized snow-vehicle. Edgar and Allen Hetteen and David Johnson of Roseau, Minnesota were among the first to build a practical snowmobile in 1955–1956, but the early machines were heavy (1,000 lb/450 kg) and slow (20 mph/32 km/h). Their company, Hetteen Hoist & Derrick Co., became Polaris Industries, a small snowmobile manufacturer.
It was only in 1960, when engines became lighter and smaller than before, that Bombardier invented what we know as the modern snowmobile in its open-cockpit one- or two-person form, and started selling it as the "Ski-doo". Competitors sprang up and copied and improved his design. In the 1970s there were over a hundred snowmobile manufacturers. From 1970 to 1973 they sold close to two million machines, a sales summit never since equalled, with a peak of half a million in 1971. Many of the snowmobile companies were small outfits and the biggest manufacturers were often attempts by motorcycle makers and outboard motor makers to branch off in a new market.
