James Pickard

James Pickard

James Pickard was an English inventor. He modified the Newcomen engine in a manner that it could deliver a rotary motion. His solution, which he patented in 1780, involved the combined use of a crank and a flywheel.

James Watt, who was a contemporary of James Pickard, circumvented the latter's patent by inventing an alternative mechanical device, the so called sun and planet gear.
