IMPROVEMENT IN PLOWS.

Spcciiication forming part of Letters Patcnt dated February '20, 1835.

To all whom it may concern Be it known that 1, BENJAMlN JOHNSON, of Hickory Grove, in the county of Bond and State of Illinois, have invented a new and useful Improvcment in the Carey or Bull Plow; and I do hereby declare that the following is a full and exact description thereof.

Take the common or bnll plow-irons, either cast or wrought, which shall bc so constrncted as that the lower corner of the share behind shall fall a little behind a point parallel with the center of the wing. At the top of the wing make an eye on the common plan an inch and a half deep. of a suificient strength to beara heavy dralt by riveting and weldiug. The heel of the plow is to extend upward nearly to the same height with the wing, with an eye of the samo strength and dimensions formed on the hind part of the said heel at the top. Attach to the under edge of the wing behind, either by rivetiug-screws, sockets, or eyes and wcdges, or by any other suflicient means, three ribs, more or less, these ribs to be made of wood or iron, and to extcnd behind neurlyhorizontal, and to be sol constructed and arranged as to describe the cnrve or mold-board; the first rib to project or extend nearly equal to two-thirds of the width of the share, measuring across the bottom, and to be placed on the wing nearly at a point one-third ot' the distance between the lower corner ot' the wing and the top of the wing; the top or npper rib to be placed just below the eye at the top of the wing and to extcnd nearly twice as far back from the share as the first rib; the intermediate ribs to extend so far back that their extreme points shall be, with the extreme points of the bott-om and top ribs, nearly on a right line \vith each other. These rihs are to be sufliciently strong, and from one to two or two and a half inches in width, and the spaces between them, when placed upon the wing, 'may vary in the same degrce.

The wood-work or stock-The beam is to rest upon the two eyes, before described, and, if the irons are not high enough to raise the beam to the proper h'eight, that part of the beam which rests upon the eyes can be increased in thickness or depth by an ofi'set, so as to raise all the beam forward of the eyes to a suflicient height, that part of the beam forward of the first eye to project the nsual length, and that part behind the last eye to extend from six to ten inches back of said eye, according to the size of the irons. The beam is secured to the irons by bolts passing up through the eyes and beam and fastened by screws and taps, the handles to be placed one on each side et' the beam, and secured by bolts and screws passing through them and the beam. They must spread behind, with a round bar between them in the usnal manner.

What I claim as my own nvention, and not previously known in the aboredescribed improvement, is the following:

l. The first and most important is in the use of the ribs in place of the common moldboard.

2. The heel of the plow extending up to the wood.

3. The plan of stocking the plow.

The advantages of the first are that the draft is rendered much lighter in conseqnenee of their being less frietion, the spaees between the ribs preventing that clogging and aceumulation of earth and soil common to the mold-board, and that all or any part of the ribs can be taken oti' at pleasure and a heavy plow made light, according to the work to be performed. By the second the stock is much Simplified and rotting prerented, there being no wood coming in contact with the earth. By the third the cost of the plow with this improvement will be much less than those in common use, it being so simple and ofso cheap construction. By this means, also, the piteh of the plow can be regulated in a moment by the screws and bolts passing through 'the eyes and beam. 'l'he durability of the plow, so t'ar as the stock and rihs are concerned, is greatly iucreased from the fact that all the wood is above ground, and no joints arc exposcd to receive the water, and therehy occasion rot.

For acomplete exemplitication ot' the above reference is made to the model deposited in the Patent Otiice and the drawing and \vritten references accompany ing this application.

In testimony that the above is a true specitication of my said improvement, as above dcscribed. I have hereunto set my hand this 30th day of December, A. D. 1834.

BENJAMIN JOU NSON.
