Frederick Graff’s drawing of the 1815 steam engine, adapted from a design by Englishmen Matthew Boulton and James Watt, shows the engine from the north, with Faire Mount and the reservoirs to the left of the drawing and the river to the right. The 1815 engine sat on the south side of the Engine House and was thus called the South Engine. As Graff indicated in his drawing, the Engine House was essentially open from river level to the roof in order to accommodate the massive beam and fly wheel of the two engines. While Graff showed the crank attached to the axle of the fly wheel, he left the crank shaft and the pump out of the drawing. The North Engine, designed and built in 1816 by Philadelphian Oliver Evans, advanced steam engines’ operating pressures from 2 pounds per square inch (psi) to 200 psi, a significant technological achievement.

The 1815 Engine House (shown here in an 1819 print) housed two steam-powered pumps that drew water from the Schuylkill River and pumped it into the reservoirs above the building, on top of Faire Mount. The artist showed smoke pouring from the south chimney, indicating that the South Engine was operating. The bridge just downstream was the covered Upper Ferry Bridge, an incredible 340 feet long, also completed in 1815. Designed and constructed by Lewis Wernwag, a native of Germany who had studied engineering there, the bridge opened in 1813. Formally called the Upper Ferry Bridge, it was also known as the “Colossus of Philadelphia” because — like the mythical Colossus of Rhodes — the bridge was held up only by piers at its two ends, with no intermediate supports. Made entirely of wood, the bridge was destroyed by fire in 1838.
