Description: |
| This patent is listed by some sources as being granted on 11 Jun., 1829.
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.
“A bar, or plate, of wrought iron, from four to ten inches wide, and from fourteen to sixteen inches long, is to have its ends cut off obliquely, so as to form an angle of about 46 degrees with the sides; these ends are to be steeled and sharpened. This plate is to be bent in a regular curve, lengthwise, upon a cylinder of about twenty-one inches in diameter. The plate, or share, is then to be bolted on to the helve, or chip, with one edge downwards. The specification states that among the advantages of this improved share, the following may be enumerated. Either end may be used, or the form of the ends may be varied, so as to be applicable to different purposes; it may be used either with or without a coulter, as circumstances require; it requires no mould board; is light, effective in its operation, and simple in its construction.
What I claim as new, and an improvement, in this plough, is the form of the share, which can be used at either end, and which, by its peculiar form, acts as a mould board and share, consequently, supersedes the necessity of attaching a separate mould board.
This plough is said to answer well in the district of country where the patentee resides. Where the soil is light, and the ploughing is intended to be shallow, we have no doubt of its adaptation to the purpose, and this we presume is all that is expected by the inventor.”
