Kimman Compressed-Air Engine

This small, 3-cylinder, radial, air engine was designed and made by Henry James Kimman (1862-1921), a pioneer inventor of small portable piton air drills. It is believed that the engine was built for a steering engine on a steam roller. The experience gained in the construction of the engine directed his interest to the design of air drills, in which field he made valuable contributions.
