This is a five-cylinder, two-cycle oil engine built by Kahlenberg of Two Rivers, Wisc.  Being built about 1920, it was used to power a tug boat that plied the Great Lakes.  It is 150 hp and donated to the museum when the boat was repowered by a modern diesel.  It has self contained water pump, air compressor and reversing gear.  Kahlenberg still makes marine air horns. 



This very early Evans is so different from all the others.  It is shown in the Continental Supply catalog of 1903 along with twins up to 90 hp.  History reveals that it was used in the Enfield Armory of Pittsburgh and one of the few items saved from the fire which destroyed the armory.   It definitely has similarities to the common Evans but perhaps this one was built in Chicora before Evans moved to Butler. 



This very large 40 hp engine, with 12 x 24 bore and stroke, was built by National Transit of Oil City, PA. It is 1902 and the last model designed by John Klein.  It weighs about 10 tons!  It pumped crude oil in Buckeye Pipline’s Braden Station in southern Ohio.  It features the Klein pneumatic governor.

Hornsby Akroyd


This 35 hp engine was actually the Model HA built by DeLaVergne of New York City.  It was a licensee of the English Horsby-Akroyd.  Built about 1902, it was a low pressure oil engine capable of burning the crude that it pumped.  It was used in York Station, a Buckeye Pipeline installation near Zanesville, Ohio.  It came to Coolspring in 1969 on the old Reo truck.
