Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A man engine is a mechanism of reciprocating ladders and stationary platforms installed in mines to assist the miners’ journeys to and from the working levels. It was invented in Germany in the 19th century and was a prominent feature of tin and copper mines in Cornwall until the beginning of the twentieth. In the Cornish examples the motive power was provided by waterwheels, or one of the mine's beam engines. Originally operating without a flywheel, this offered a reciprocating motion of, typically, twelve to fifteen feet (three to five metres). The engine would be linked to a series of beams – known as "rods" – fastened together and reaching to the bottom of the mineshaft. Small platforms would be attached to the rods at the same distance apart as the engine stroke.
