IMPROVEMENT iN PLOWS.

Specification forming part of Letters Patent No. 8,794, dated March 9, 1852.

To all 'whom it may concern:

Beit known that I, JosHUA 'WOODWARTL of Haverhill, in the county of Grafton and State of New Hampshire, have invented certain new and useful Improvements in VVeeding Plows or Apparatus; and I do hereby declare that the f'ollowing is a f'ull, clear,and exact description of the principle or character which distinguishes it from all other things before known, and of' the usualmanner ot' malring, modifying, and using the same, reference being had the accompanying drawing, making apart thereof.

The purpose of' my invention is to furnish a weerler or plow that shall et'fectn-ally eradicate the weeds from land with the least power in the steadiest and surest manner.

The construction is as follows:

The beam a, handles b, and mold board share c are similar to many plows now in common use. Above the ordinary share I place a piece that insures the turning of the weeds under by curving over, as is sometimes effected more or less perfectly in ordinary plows. The sole ot' the plow el is fiat and solid, and upon it is secured an angle-plate, e, by proper bolts, so as to be shifted to or from the landside, and to the angle required Vfor the Work to be done, the angle being determined according to the direction to be given to the mold-board. The

part perpendicular to the sole ot the plow is thin, so as readily to cut its way into the ground whent has secure hold. By this means the ground is etfectually cleared of weeds in the following way. The plate e being set it is malle to enter the ground, while the edge of the share just skims below the surface, eradiating the weeds nearly up to the corn as is desirable, while it does not disturb the roots of' the corn. The guide e causes the plow to run steady throughout its whole course, which is absolutely necessary, especially where the ground is apt to clog, as any devia-tion under those circumstances at once prevents the moldboard from scouring. Y

It will be perceived that I make the upper part of the moldeboard movable, and project its rear end out beyond the cutter, which is essential to eftectually cover the weeds.

Having thus fully described my weeding plow, what I claim therein as new, and for which l desire to secure Letters Patent, is-

The plate e, constructed, arranged, and combined with the plow, substantallyin the man` ner and f'or the purpose set forth.

JOSHUA WOODWARD.
