Serial No. 535,993.

fo all whom "it may concern:

Be it known that l, lllicnmrr B. MiroiruLL, a citizen of the United States, residing at Bedford, in the county of Lawrence and State of indiana, have invented a new and useful Harrow, Drag, and Pulverizer, of whichv the following is a specification.

rlhis invention has relation to a combined harrow, draO' and pulverizer and it consists in the novel construction and arrangement of parts hereinafter shown and described.

rllhc object of the invention is to provide an implement of the character stated which is of simple and durable structure and which includes a series of means secured together in close order and carrying a series of blades so mounted thatl they may be readily reversed in their positions upon said cam. The beams are provided with inclined under surfaces and it is upon these surfaces that the said blades are mounted and all of the beams except the last beam of the series are provided in their rear edges with slots or lterfs adapted to receive the forward end portions of the blades upon the next adjacent beam toward the rear of the structure. The foremost beam of the series is preferably devoid of the said blades. rlhe blades are formed from sheet metal having at their upper edges laterally disposed flanges, the flanges at the rear ends of the blades eX- tending from the blades in the opposite direction from the flanges at the forward ends thereof. The said flanges are disposed at right angles to the body portions of the blades.

ln the accompanying drawings: Figure i is a bottom plan view of the harrow, drag and pulverizer.` Fig. 2 is a side elevation of the same. Fig. 3 is a perspective view of one of the blades detached.

The implement includes a series of beams l arranged in close order and having lower inclined surfaces 2. rlhe said beams may be secured together by means of a bar or bars 3 or any other suitable means. All of the beams l except the rearmost beam of the series are provided at their rear edges with vertically disposed slots or kerfs il.

0n all of the beams l except the foremost beam of the series are mounted blades 5. rihe said blades 5 are formed from sheet metal and consist of plane body portions having at their upper edges laterally disposed flanges rEhe flanges G at the for ward ends of the blades 5 extend in the opposite direction from the flanges t5 at the rear ends of the said blades and all of vthe said flanges lie at right angles to the body portions of the blades. The flanges are provided with bolt perforations 7 which are adapted to receive bolts S whereby the said blades are secured in position against the under inclined sides or faces of the beams l. The blades 5 may be positioned upon the beams l in any desired relative relation and it will be seen that when the rear ends of the blades (5 have become worn in consequence of use the said blades may be reverse-d in their positions by removing the securing devices S and turning the blades around and replaeing the said securing devices. r.the forward ends of the blades 5 are inserted in the slots or lterfs 1l of the beams lv just ahead of 'that beam upon which the blades are mounted and that the forward portions of the blades are braced against lateral strain. 'lhe bolts S hold the blades against rearward movement or movement away from the beams l. inasmuch as the blades are relatively long and are in an inclined position as the harrow is drawn over the surface of the ground they will cleave the soil effectually and cut any material that may lie at the surface or just below the surface of the same. 'ihe blades are securely held in place by three instrumentalities namely, the two bolts, one located at each side of the blade and the kerfs or slots whichl receive the forward ends of the blades. By reason of the fact that the blades are of such configuration that they may be reversed in their positions upon the beams when the rear ends of the blades, as first positioned, have become v-Vn 'to such an extent as to be ineffective nnworn ends are disposed toward the .rear id the usefulness of the implement is prolong l.

Having thus described my invention, wh@ l claim as new and desire to secure by Let.- ters Patent is:

it harrow composed of beams having inclined under surfaces, and provided at their rear edges with yerticnlry disposed slots, blades formed from sheet netal and having laterally cisposed flanges at their upper edges, the flanges at the forward ends of the blades extending in the opposite direction from the v[langes at the rear ends of the blades, securing devices passing through said flanges and attaching the blades to the inclined surfaces of the beams, the blades upon one beam having their forward end portions lying in the slots at the rear edge of the next adjacent beam toward the front of the structure.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.

VICKLIFF B. MITCHELL.
