HARROW.

SPECIFICATION forming part of Letters Patent No. 291,414, dated January 1, 1884.

Application filed March 15, 1883. (No model.)

To aZZ whom it may concern Be it known that I, SAMUEL SHOEMAKER, a citizen of the United States of America, residing at Nokomis, in the county of Montgomery and State of Illinois, have invented certain new and useful Improvements in Harrows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of this specification.

This invention has relation to a combined harrow and corn-marker; and it consists in the construction and novel arrangement of parts, as will be hereinafter described, and particularly pointed out in the appended claim.

In the accompanying drawings, Figure l is a rear perspective View of my improved combined harirow and corn-marker, and Fig. 2 is a sectional view.

The letter A designates my improved harrow, which is composed of the drag-bars or beams B, secured together transversely at suitable distances apart by means of the crossbars 0. These drag-bars or beams are made in the form of a triangle, or approximately so, 7

their lower edges forming sharp surfaces, to break up the olods of earth. These beams are also provided with inclined openings, to receive the teeth 0, which are driven, or otherwise secured', therein. The middle beam of the harrow has its openings inclined in the opposite direction to that of the two outer beams,

' and owing to this position of the teeth. in connection with the sharp edges of the beams, the implement gives the clods of earth athorough breaking up, to put the ground in proper order for planting.

Secured to the top of the middle beam, and arranged at equal distances apart, are the uprights or bearings b b b, the purposes of which will be hereinafter explained.

The letters D D D represent corn-markers composed of the long arms ff f,having shovelplows attached to their outer ends, and each of their inner ends are provided with bearings or hinges d d d, which may be made of leather or other suitable flexible material, which are secured to the uprights or bearings of the said middle drag-bar (5r beam, so that the plows are permitted to vibrate vertically. These markers serve to lay off the ground after the harrow has passed over the same and reduced the ground to a proper condition for marking or laying off. These-markers can be easily removed and replaced when required.

Having now fully described my invention, what I claim is- The combination,in a harrow, of the triangular bars B B B, provided with a smooth front portion, and on their rear portions with teeth inclined rearwardly at the same angle, and laterally at different angles, the bars B B B being rigidly connected to each other by crossbars 0 C, so as to provide a rigid frame, and

markers D,hinged to the central portion of the barrow-frame, the parts being constructed and organized substantially as shown, and for the purpose set forth.

In testimony whereof I affix my signature in 1 presence of two witnesses.
