This paper describes the brief history and coupling mechanism of Wilson-type automatic coupler. In Japan, this type of coupler was adopted by some light railways and industrial railways such as in mining plants, and it is presumed that this coupler was invented by John Wilson in England, and manufactured by American company, i.e., National Malleable and Steel Castings, Co. and imported to Japan after the World War II. This coupler is very simple in its structure, only moveable part is key, but it has automatic coupling function just as common automatic coupler, and in Russian National Railway, bigger-sized coupler alike Wilson type is used universally in heavy duty.
