ATTACHMENT For: CULTIVATORS.

SPECIFICATION forming part of Letters Patent No. 312,574, dated February 17, 1885.

Application filed July 1, 1864. (No model.)

To all whom it may concern.-

Be it known that I, JOHN E. MITCHELL, a citizen of the United States, and a resident of Fowler, in the county of Benton and State of Indiana, have invented certain new and useful Improvements in Attachments for Cultivators;

and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art towhich it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a top view of the attachment. Fig. 2 is a rear view of the same. Fig. 3 is a horizontal sectional view of the beam on an enlarged scale. Fig. 4 is a vertical section on line a; 00, Fig. 8. Fig. 5 is a vertical crosssection; and Fig. 6 is a perspective view of the attachment, showing it attached to a common cultivator.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to harrowing and scraping attachments for cultivators or plows;

and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the axle of a straddle-row cultivator. B B are the wheels, and the cultivator-beams O are movably connected in any suitable manner to the axle of the frame, being shown in the drawings as hinged in pairs to the axle, and formed with the standards D integral with the beams, and formed at the rear ends of the same.

The beams may, if desired, be provided with handles E, for the purpose of guiding them, or be provided with any other suitable means for guiding them, and the beam nearest to the middle of the cultivator, and consequently nearest to the row, is somewhat shorter than the beam upon the outside.

F is a beam similar to a barrow-beam, and is secured by clips G to the lower ends of the cultivator-standards, standing obliquely to the line of draft, and having its inner end pointing' forward by reason of the inner beam being shorter than the outer beam. Teeth Hare secured in the usual manner in the beam F, be-

ing common barrow-teeth, and the inner end of the said beam is provided with a vertical longitudinal slit or kerf, I, having the teeth resting with their upper portions in recesses 5 J in the inner sides of the slit, and clamped between the same by means of nutted bolts K, passing transversely through the slitted end of the beam.

Blades L, having their lower edges sharp- 6o ened and having a longitudinal and a transverse curve, are pivotally secured at their forward ends to the lower ends of brackets M by means of bolts projecting at right angles from the beam toward the rear, and the rear ends of these blades, which are so-called gopher blades, are provided with nutted bolts N, which slide adjustably in longitudinal slots 0 in the lower ends of rearwardly-projecting brackets or rods 1 secured at their forward ends to the beam. The blades increase, preferably, in length toward the outer or rear end of the beam, and it will be seen that the rear ends of the blades may be raised or lowered, as desired, by sliding the nutted bolts in the 7 slots and adj usting them in the same. Vhen the attachment is drawn forward, the blades will be rearwardly and inwardly inclined, throwing the dirt over which the attachment is drawn toward the row; and it will be seen that the teeth will stir up the soil, whereupon the blades will afterward cut all remaining grass, roots, or weeds and leave them in rows varying in height according to the elevation of the rear ends of the said blades. The teeth 8 5 at the inner forwardly-pointing end of the beam may be raised or lowered at will, being clampedibetween the sides of the slit in that end of the beam,and they are preferably raised, so as not to injure the roots of the plants be- 0 tween which the attachment is drawn, or may be entirely removed after the plants become of such a height that they cannot pass over them. In this manner the attachment. will stir the soil effectually with the teeth, out weeds 5 with the blades, and leave all weeds and large clods in rows between the rows of plants, the said weeds and clods being delivered at the rear ends of the oblique blades.

Having thus described my invention, I claim- In a cultivator attachment, the combination of the cultivator beams and standards, the beam attached to the lower ends of the standards obliquely to the line of draft, and having a series of teeth, one or more of which at the 5 inner end of said beam are vertically adjust- JOHN E. MITCHELL.

able, and a series of blades pivotally attached to brackets extending downwardly from the Witnessesz said beam, and connected adj ustably to arms FLETCHER SMITH, extending rearwardly from the beam, as and l J osEPH F. WARNER.

In testimony that I claim the foregoing as my own I'have hereunto affixed my signature in presence of two witnesses.
