Improved Greene Engine: Before Restoration

Greene crosshead

The images below show the engine in the Rhode Island Cardboard Company building.

The engine was remarkably intact, but more than a little rusty from sitting in a leaky building for more than 70 years.

A view from the crankshaft end.You can see the multitude of oilers on the eccentrics.You can see how rusty the strongback was. It collected a puddle of water every time it rained, for 70 years.You can see the engine maintenance tools in a rusty pile on the floor.The dark objects in the background are part of the alarm and emergency shutoff for the engine.The dashpots that close the steam valves.Another view of the rusty strongback and eccentrics.The two rods in the foreground operate the steam and exhaust valves.The back of the eccentrics.
