Need to cut a path through the snow? Maybe you should get an auto sleigh. Even in the early years of automobiles, people were converting their cars into self-powered sleighs. One common arrangement was to place the car on skids and tie the engine drive into one or two helical screws. Pictured above is a converted Hupmobile Model 20 Torpedo Roaster. Below is a patent drawing for a similar car design filed by Charles E.S. Burch of Seattle in 1907. You can read more about these cars at The Old Motor.
