Cutler and silversmith.
1833 Patented a method of stamping out spoons, ladles, forks, etc., in a single blow, needing only trimming of the flash and polishing to finish the article. The upper die was attached to a heavy hammer, guided by a frame, and raised by a rope worked by a capstan. It was essential that after releasing the trigger, the workpiece only received a single blow, and was not spoiled by a succession of blows which would have resulted due to rebounding. After rebounding, the ascending hammer was caught by pawls catching in ratchet teeth on both sides of the guide frame. Described and illustrated by Andrew Ure in 'A Dictionary of Arts, Manufactures, and Mines' in 1839.
