IMPROVEMENT IN SHOVEL-PLOWS.

Specification forming part of Letters Patent No. 5,130, dated May 29, 1847.

1'0 all whom it may concern Be it known that 1, RICHARD J; GATLING of the town of Murfreesborough, in the county of Hartford and State of North Carolina, haveinvented a new and useful Improvement in the Cultivator for Cultivating Cotton and other Plants called Gatlings Improved Shovel- Plow, which is described as follows, reference being bad to the annexed drawings of the same, making part of this specification.

Figure 1 is a perspective view of the cultivator. Fig. 2 is a plan of the double share. Fig. 3 is a plan of the reversible orchangeable point. Fig. 4 is a side view of the same. Fig. 5 is a plan of one of the wings.

From considerable experience as a cottonplanter and much observation in regard to the nature of the cotton-plant and of the difierent soils and climates in which it is cultivated in the Southern States, I long since came to the conclusion that the common shovel-plows and cultivators in general use among our planters were not adapted to produce the results desired. I therefore turned my attention to the improvement of this important implement of agriculture, and the result is the production of the article represented in the annexeddrawings and described in the following specification. As the young cotton-plants increase in strength the soil is required to be stirred and brought up around them at the various periods of growth, according to the strength of the plant and the nature of the soil, which is.

easily determined by the planter, and which he accomplishes with ease by the use of the common hoe; but when he makes use of the common cultivator drawn by a horse he cannot regulate the degree of pulverization of the earth and the quantity to be brought around the roots of plants so exactly as with the hoe.

In order to approximate to the required results I form the cultivator in the manner represented at A A, Figs. 1 and 2, the double share or cultivator being made of good castiron, convex on top and concave underneath,

- which fit into corresponding depressions cast in the body of the plow, to hold it firmly in its proper position during the operation of opening a furrow. 1

B is an aperture in the center of the cutter,

to admit a screw, B,.Fig.1, thatholdsitfirmly in its seat on the body of the plow. This point or cutter thus made and arranged admits of four changes of position. The point can have more than one hole through it, if desired, as 1 earth after being cut and stirred up by the point B and double share A, the rest of the loosened soil being directed against the cottonplants by two oblique wings or adjustable mold-boards, E, attached to the hindermost ends of the double share, as shown at E, Fig. 1, or not attached to thedouble share, as shown at e in Fig. 2. These wings are made adjustable, so that they can be extended orv contracted in width at pleasure, according to the quantity of earth to be thrown around the plants by means of a row of holes in each of them, which admit of a bolt or pin, G, fastened in an oblique brace, F, extending from the central bar, D, to the rear end of the share A. There is one of said braces on each side of the center of the plow. In Fig. 2 the braces f are represented as braced to the beam by other tion of this reversible mold-board can be reversed at pleasure, so as to bring the lower edge uppermost. v I

The cutter H, Fig. 1, can be cast solid with the body of the plow, or it may be made in a separate piece of wrought-iron, if desired.

The beam I, handle J, and sheth K may be made and arranged in the usual manner.

What I claim as myinvention, and desire to secure by Letters Patent, is-

1. Making the cultivator with adjustable sliding wings E, of a rhomboidal form in their cross sections, arranged and operating in the I 3. Making the point in the form of adouble manner and for the purpose described. wedge, with wings or shoulders B to fit into 2.

tached, and upon which the adjustable wings Witnesses:

or mold-hoards E are placed, in the manner WM. P. ELLIOT,

and for the purpose set forth. 7 A. E. H. JOHNSON.
