The Superior Piersen: Gas Engines and Telegraph Equipment

The Piersen Manufacturing Company of Topeka, Kan., never quite succeeded, although they produced exceptional gas engines and telegraph equipment.

Piersen's Flywheel
Closeup of the Piersen's flywheel/radiator. The flywheel spins with the crankshaft, centrifigul force pushing cooling water through the radiator tubes. The upper hose feeds hot cooling water to the flywheel/radiator, which is then returned via the lower hose to the bottom of the reservoir just visible in the upper right of the picture.
