    It was an improvement on the design credited to Thomas Savery. Where the steam was condensed faster by use of cold water. The improvement was made after a mining operation complained that a steam engine was working too fast. A crack was discovered in the cylinder wall that was letting cold water into the steam chamber. James or his workman fixed it, then went home and drew up a patent on a new improved engine.

    Steam entered the cylinder raising the piston. When it got to the top of its stroke a workman turned a lever that stopped steam from entering the cylinder and then condensation of the steam brought the piston back down.

    Later on a man on night shift was caught at a pub, instead of minding the engine. It was found that he had rigged up a method to turn the valves on and off with out being there. He got fired and his idea was patented by some one else.
