COMBINATION PLOW-BLADE.

Specification of Letters Patent.

Patented Feb. 26, 1907'.

Application filed August 13, 1906. Serial No. 330,398.

To CL whom it may concern.-

Be it known that I, Lnwis J onNsoN, a citi zen of the United States, residing at Ituston, in the parish of Lincoln and State of Louisiana, have invented a new and useful Combination Plow-Blade, of which the following is a specification.

This invention relates to a blade for a plow intended more particularly for the cultivation of cotton; and it has for its principal object to provide a single blade so designed as to take the place of the different plows ordinarily employed in the cultivation of cotton such as the scooter, cultivator, shovel, and heelsweepso that the cotton can be cultivated by a single plow, different-sized blades being employed, of course, at various stages in the growth of the cotton.

A further object of the invention is the provision of a blade of this character which is of simple, inexpensive, and substantial construction, and comprises a unitary structure, the parts of which are integrally connected.

With these objects in view and others, as will appear as the nature of the invention is better understood, the invention comprises the various novel features of construction and arrangement of parts, which will be more fully described hereinafter, and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one of the embodiments of the invention, Figure 1 is a perspective View of the combination-blade. Fig. 2 is a plan View thereof. Fig. 3 is a front view. Fig. 4 is a front view of the blade mounted on its standard, the blade being drawn on a reduced scale.

Corresponding parts in the several figures are indcated throughout by similar characters of reference.

Referring to the drawings, 1 designates the body of the blade, having a depending portion 2 intermediate its ends, that forms a shovel. On the right hand of the blade viewed from behind is a wing 3, forming the scrape, and the opposite end or wing 4 at the left-hand forms the sweep. The blade is made of metal of suitable thickness and is wrought or otherwise formed into the desired shape. The body 1- is provided with square openings 5, whereby the blade can be supported on a suitable sheth or standard 3, as shown in Fig. 4. As viewed from the front the top edge of the blade extending from the extremity of one wing to the other is horizontal, and the ends of the wings taper down wardly, as at 6, toward the point of the shovel. The lower edges 7 of the wings are approximately parallel with the top edge of the blade. The latter inclines downwardly and forwardly in a slight curve, so that the front sfde of the blade is concave. The scrape 3 curves forwardly in the form of a scoop, while the sweep curves gradually to the rear. The upper edge of the blade there fore forms a compound curve, as shown in Fig. 2. The sweep and scrape are also concave, the sweep having approx'mately the same concavity as the body 1 and the scrape a slightly-deeper concavity. The upper edge of the scrape curves over toward the front, so as to overhang the lower portion, and thereby prevents the soil from riding directly over the sweep.

With a plow-blade of the construction shown it will be readily understood that a variety of operations can be performed, so that a single plow can be used without requiring different blades, as heretofore. In the cultivation of a crop, however, blades of different sizes will be used from time to time, depending upon the stage of growth of the plants.

In the cultivation of cotton the first work is usually done with a side harrow or cultivator. In substituting the present blade for this work the plow is run down along a row with a short portion 3 of the blade next to the plants, so as to throw the dirt therefrom, while at the same time Working the ground between the rows with the middle portion of the blade. Then by traveling with the plow on the same side of the row in the opposite direction the portion 4 will be next the plants, so that the dirt can be thrown from the middle back upon the latter. After the cotton has advanced in growth various oper ations usually done with other cultivating devices may be done with the present blade, as will be readily understood by those skilled in the art.

I have described the principle of operation of the invention, together with the apparatus which I now consider to be the best embodiment thereof; but I desire to have it understood that the apparatus shown is merely illustrative and that various changes may be made when desired as are within the scope of the invention.

What is claimed is- 1. A blade for a plow comprising a body, a scrape and sweep extending from opposite edges of the body, and a shovel between them and extending downwardly from the body.

2. A blade for a plow comprising a body, a depending portion forming a shovel, and oppositely-extending wings forming a sweep at one edge of the body and a scrape at the opposite edge.

3. A single-piece blade for a plow comprising a body, a depending shovel, a wing curved forwardly from one edge of the body to form a scrape, and a wing curved rearwardly from the opposite edge of the body to form a sweep.

4. A single-piece blade for a plow comprising a body having a central portion form ing a shovel, a forwardly-curved wing at one edge of the body having its upper edge overhanging the remainder of the wing, and a wing on the opposite edge of the body which curves rearwardly.

5. A single-piece blade for a plow comprising a body concaved on its front side, a central tongue forming a shovel, a concaved wing bending slightly in a forward direction from one edge of the body to form a scrape, and a wing bending slightly rearwardly from the opposite edge of the body to form a sweep.

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

LEWIS JOHNSON.
