Ancient Web: Coolspring documented a 25-ton Otto engine one

The museum’s illustrated feature connects a 175-horsepower gas engine to the 20-ton Deane pump it once drove at Brookville’s water works. Bore, stroke, RPM, and water output turn a giant machine into a researchable object. The model number is only the start; the site preserves what the engine actually did.
