from New Jersey, was granted a patent on 1 April 1807 for an iron plow. Charles Newbold, a previous plow inventor, sued for patent infringement winning $1500 in damages. Even so, Peacock's plow was an improvement, for the moldboard, share and point were cast in three separate pieces. These parts were joined, with the point of the colter entering a notch in the breast of the share. Thus if the point broke by striking a rock or root, the point alone could be replaced on Peacock's plow. If the point broke on a Newbold plow, the entire cast unit had to be discarded.
