For an improvement in the Plough; Joseph Cromwell, Cynthiana, Harrison county, Kentucky, October 9, 1834.

"The land side, share, and mould board, are each to be of wrought iron. The land side and share are to be connected at the point by welding, or otherwise, but are to be separated from the mould board. The share is to be confined to the mould board by means of a staple, or socket. The improvements claimed, consist of the means by which the share is confined to the mould board, and the hooks by which the beam and land side are confined together."
