Cool Coolspring Power Museum
A museum in the rustic hills of western Pennsylvania preserves a remarkable mechanical history.
The Coolspring Power Museum educates visitors about the evolution of internal combustion engine technology that put an end to the era of steam.
The museum’s long-time director – with the help of hundreds of enthusiastic volunteers – preserve more than 250 rare engines.
“Internal combustion engines revolutionized the world around the turn of the 20th century in much the same way that steam engines did a century before,” notes Director Paul E. Harvey, who co-founded the museum in 1985 about midway between between Punxsutawney and Brookville, Pennsylvania.
“One has only to imagine a coal-fired, steam-powered, airplane to realize how important internal combustion was to the industrialized world,” adds Harvey, medical doctor who lives across from the museum.
According to Harvey, permanent exhibits at Coolspring include stationary gas “hit and miss” engines, throttle governed engines, flame ignition engines, hot tube ignition engines, and hot air engines ranging in size from a fractional horsepower up to 600 horsepower.
Many engine enthusiasts from around the country have sent significant pieces for display, he says. The grounds, as well as semi-annual shows, have expanded with visitors from Maine to California, as well as Canada and England.
Harvey explains that early internal combustion engines produced only a few horsepower and could not replace steam engines in most applications, but by 1890 they were powerful enough for most portable or remote operations as well as many small manufacturers.
By 1900 the new power technology was replacing reciprocating steam engines for electric generation, He notes. “By 1915 they were being considered for all but the largest installations where steam turbines have since dominated.”
Harvey and fellow enthusiast John Wilcox began collecting engines in the 1950s. Their collections were the basis of displays that would greatly multiply. The museum now is housed in 20 buildings that, besides its own large collection, contain many pieces placed there on loan.
Harvey says the vision of Coolspring is “to be the foremost collection of early internal combustion technology presented in an educational and visitor-oriented manner and to provide an operation that will gain support and generate substantial growth.”
The collection documents the early history of the internal combustion revolution. Almost all of the critical components of today’s engines have their origins in the period represented by the collection (as well as hundreds of innovations no longer used).
Some of the engines represent real engineering progress; others are more the product of inventive minds avoiding previous patents. All tell a story.
Although the museum’s focus is on stationary engines (with perhaps the largest collection in the world), Harvey explains that no museum of internal combustion engines would be complete without at least a few vehicles in its collection.
Among the antique heavy truicks and semis, is a rare petroleum well service rig. The Hanley & Bird Well Bailing Machine was designed to clean a well by lifting water, sand, and debris from the bottom of the well using a “bailer” attached to a cable, notes Harvey. Five were built and the museum’s example is the only one to survive.
“It was donated to the museum by EXCO Resources, the successor to H&B,”Harveys says. “It is very interesting as it uses a chain drive Mack rear end and a Ford front axle.”
Harvey recalls seeing it driving through Coolspring on the way to service local natural gas wells, adding that the museum displays it with the mast raised and ready to work. “It certainly shows the ingenuity of the local gas industry,” he concludes.
The Coolspring Power Museum collection includes many engines used to power multiple wells in America’s first oilfields. The museum is off Route 36 midway between Punxsutawney and Brookville in western Pennsylvania.
“Internal combustion engines revolutionized the world around the turn of the 20th century in much the same way that steam engines did a century before,” concludes Harvey. “You have only to imagine a coal-fired, steam-powered, airplane to realize how important internal combustion was to the industrialized world.”
The Coolspring Power Museum hosts many events in the spring and summer, including the popular “History Day and Car, Truck & Tractor Show” in June.
