PLOW.

I Application filed August 16, 1922. Serial No. 532,198.

To all whom it may concern:

Be it known that I, lViLLmnr JACKSON BURNETT, a citizen of the United States, residing at Thomasvilla in the county of illhomas and State of Georgia, have in rented a new and useful Plow, of which the following is a specification.

This invention relates to plows of that type known as middle breakers or middle bursters, one of the objects of the invention being to provide a novel assembly of a point, wing and sweep adjustably and detachably connected whereby the plow can be operated either for cleaning out a fur row or for subsoiling.

Another object is to provide simple and efiicient means for holding the parts to gether and assembled with the standard.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a front elevation of the plow, the beam being broken away.

Figure 2 is a side elevation, the beam being broken away.

Figure 3 is a perspective view of the point.

Figure 4 is a perspective view of the wing.

Figure 5 is a perspective view of the connecting stem.

Figure 6 is a front elevation of the plow, showing the parts adjusted for subsoiling.

Referring to the figures by characters of reference 1 designates a portion of a plow beam to which is connected an elongated loop 2 forming the standard of the plow. To the lower end of this standard may be connected a runner 3 having sweeps 4 se cured to the sides thereof and diverging rearwardly. The construction and mounting of the sweeps and runner does not in itself constitute any part of the present rention and, therefore, it is not deemed necessary to describe or show the same in detail.

Straddling the standard 2 is a transversely bowed stem 5 having an elongated slot 6 therein. From the lower end of this stem projects a pointed backing plate 7 having openings 8 therein.

A point, one form of which has been illustrated in Figure 3, is adapted to be placed upon the backing plate 7, this point, which has been designated by the numeral 9, being formed with a. central longitudinal ridge 10 and with rearwardly diverging extensions 11 the lower edges of which are adapted to scrape along the ground as shown at 12. Bolts 13 are extended through openings 14 in the upper portionof the point and are secured within the openings 8 in plate 7.

A wing plate 15 is adapted to be placed upon the stem 5 and is so shaped at its lower end as to fit snugly against the middle portion of the upper edge of the point 9.

This plate has upwardly diverging wings 16 and a central longitudinal slot 1?. Slot 17 receives a king bolt 18 which is extended through the slot '6 and between the sides of the standard 2 and is engaged by a nut 19 which, when tightened, serves to bind the several parts together securely.

When the wing plate 15 is set up against the point 9 and the parts securely fastened, as shown in Figures 1 and 2, the plow is ready for use to clear out furrows. When it is desired to use the plow for subsoiling the bolt 18 is loosened and the stem 5 adjusted downwardly so as to support the point 9 below and spaced from the lower end of the wing plate 15. By then tightening the bolt 18 the parts will be held against relative movement. (See Figure 6.)

It is to be understood that points of different shapes and sizes can be used and that different kinds of wing plates can also be employed.

What is claimed is In a plow the combination with an elongated loop constituting a standard, of a backing plate, a longitudinally channeled slotted stem integral with the backing plate and straddling the standard, a point detachably secured to the backing plate and having its upper edge outstanding from the ste t o s t te an abutment, a wing pl te bearing against the slotted stem and abut- In testimony that I claim the foregoing tlng the edge of the polnt, the front :taces of as my own, I have hereto aflixed my slgnathe polnt and plate belng flush at then ture 1n the presence of two wltnesses.
