Designed especailly for hoists, pumps, and other applications, the Automatic engine of 1912 was a takeoff from marine design. Many builders specilaized in marine and launch engines, but also adapted some styles to stationary uses. The two-cycle design gave inherent simplicity, plus the advantage of an excellent ratio of weight to horsepower.
Automatic Machine Company manufactured gas engines in 1912 and then metalworking machinery from 1921-1941. During this time they manufactured the Coulter shaping planer. In 1941, the company was called Automatic Machinery Manufacturing Co and in 1942, it became the James Coulter Machine Co.
