This fire engine is a simple pump, which was typically mounted on a wagon to make it easily moveable to the location of the fire. The same wagon might also carry a supply of water, or it could be drawn from a different wagon, a pond, or reservoir if one were near enough to the fire. Once the engine was on location, hoses could be attached to the two holes under the engine, one to draw in the water and one to discharge it onto the fire. This engine required fewer workers and was capable of delivering water more effectively than a bucket brigade, but it was still dependent on the availability of water near the fire.
