Patrick J. Shouvlin learned his trade working as an apprentice in a railroad maintenance shop in his hometown of Springfield, Ohio. After completing his apprenticeship he worked as a master mechanic for the Chicago, Burlington and Quincy Railroad and eventually wound up on the west coast. When he learned of the oil boom that was underway, he decided to return to Ohio and go into business for himself.
Engines used for pumping in the oil fields were subjected to unusually harsh operating conditions. Many of the brands competing for a share of this market just weren’t up to the challenge. PJ set out to build engines specifically for the oil fields, His engines would be simpler, sturdier and designed for long hours of continuous operation with little maintenance. They would be Superior engines.
In the early years the Superior Gas Engine Co. depended on nearby oil field operators for most of its revenue but in 1894 Shouvlin collaborated with several other firms to form the National Supply Co. that would be headquartered in Pittsburgh, Pa. National Supply would be the distributor for the member companies. As the market expanded Superior’s product line grew to meet new demands. By 1914 they offered horsepower options from 20 to 100 and hopper and tank cooled engines with 2 ½ to 15 hp. ratings as both stationary and portable models.
