From Wikipedia, the free encyclopedia

The Hierapolis sawmill was a Roman water-powered stone sawmill at Hierapolis, Asia Minor (modern-day Turkey). Relationship to the second half of the third century AD,[2] the sawmill is taken into account the earliest identified machine to mix a crank with a connecting rod to kind a crank slider mechanism.[1]

The watermill is evidenced by a raised relief on the sarcophagus of a sure Marcus Aurelius Ammianos, a neighborhood miller. On the pediment a waterwheel fed by a mill race is proven powering through a gear train two frame saws slicing rectangular blocks by the best way of connecting rods and, by mechanical necessity, cranks (see diagram). The accompanying inscription is in Greek and attributes the mechanism to Ammianos’ “expertise with wheels”.[3]

Different sawmills[edit]

Additional Roman crank and connecting rod mechanisms, with out gear practice, are archaeologically attested for the sixth century AD water-powered stone sawmills at Gerasa, Jordan,[4] and Ephesus, Turkey.[5] A fourth sawmill presumably existed at Augusta Raurica, Switzerland, the place a steel crankshaft from the 2nd century AD has been excavated.[6]

Literary references to water-powered marble saws in Trier, Germany, may be present in Ausonius‘ late 4th century AD poem Mosella. About the identical time, additionally they appear to be indicated by the Christian saint Gregory of Nyssa from Anatolia, demonstrating a diversified use of water-power in lots of components of the Roman Empire.[7]

The three finds push again the date of the invention of the crank and connecting rod mechanism by a full millennium;[8] for the primary time, all important parts of the a lot later steam engine had been assembled by one technological tradition:

With the crank and connecting rod system, all components for developing a steam engine (invented in 1712) — Hero‘s aeolipile (producing steam energy), the cylinder and piston (in steel power pumps), non-return valves (in water pumps), gearing (in water mills and clocks) — had been identified in Roman occasions.[9]
