Description
The Barker’s Mill is a simple hydraulic machine named for Robert Barker (d. 1745), a British physician and Fellow of the Royal Society. Much of what we know about it’s history comes from John Theophilus Desaguliers who, in the second volume of his Course of Experimental Philosophy (London, 1744), mentioned a “new invented Mill” introduced by Dr. Barker, adding that “I took the Doctor’s Hint, and made the following working Model of it, which I shew’d the Royal Society the Experiment of, at their last Meeting this Summer.” Desaguliers also discussed an improvement to the breast mill contrived by “the learned an ingenious Dr. [Robert] Barker, whose skill in Mechanicks as well as all Parts of Mathematicks and [Natural] Philosophy is well known.”
