Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
"That others may discover where the merit of the invention lies, we give the whole specification, as it is short. All the peculiarity that we perceive in it, is, that the mould board is made partly of iron, and partly of wood; it being widened out at top, by means of the latter material.
John Rhodes' newly invented plough, differs from other ploughs now in use, as follows: The land-side and share are of wrought iron, and laid with steel; the wing welded to the bar in front, and raised so as to form the principal part of the mould, extending back to the right handle, and fastened to said handle with a bolt and screw; also a piece of wood extending from the sheath to the handle, and fastened either with a screw or rivet, and placed on the top so as to form the balance of the mould; also a bolt with a screw passing through the mould and sheath, connecting them together; the bolt connecting the beam and share together locking in the socket; the coulter being locked on the point of the share, and fastened to the beam on the land-side with a clamp and two screws.
This plough may be used with or without a coulter."
