Mill Factory Rope Drive
On real mill engines the power was transferred from the on steam engine to each floor of the factory by ropes running from the flywheel machined with as many as 40 rope grooves to pulleys for each floor, power was then transferred to overhead shaft drives and pulleys to each machine. Ropes were used as they were much more effective than belts. Belts slip more than ropes which run in V grooves. Multiple ropes were used to connect each pulley to the main flywheel so that if one broke work could continue uninterrupted until the next scheduled maintainance period.
