Application filed February 1, 1906. Serial No. 299,014.

To all whom, it may concern:

Be it known that I, THOMAS H. SPARKS, a citizen of the United States, residing at l/Vichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Listed-Corn Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which forma part of this specification.

This invention relates to new and useful improvements in listed-corn cultivators and the object of the invention is to produce a device of this character comprising a sled so arranged that the dirt may be thrown into the furrow before the sled has passed by, while the back end of the runners are so constructed as to cut into the side of the ridge and cause the dirt to be pushed toward the corn. By this construction the dirt is brought in from the bottom of the ridge, and as it comes up beneath the leaves of the corn it has a tendency to straighten the stalk instead of mashing it down, as is the case when dirt is thrown from the top of the ridge, and when a sufficient quantity of dirt is thrown to cover the corn it is left in an upright position and will soon reappear above the surface.

The invention consists, further, in a device of the character described in which adjustable shields are provided to regulate the amount of dirt thrown, thus making the de vice positive in action and regulating the desired amount of dirt to be thrown to the corn.

The invention consists, further, in various other details of construction and combinations and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a top plan view. Fig. 2 is a side elevation. Fig. 3 is a bottom plan view. Fig. 4 is a central longitudinal section showing parts in elevation. Fig. 5 is a rear end view, and Fig. 6 is a cross-sectional view.

Reference now being had to the details of the drawings by letter, A A designate the two runners, whichare similar in construction and have their forward ends beveled and inclined. Each of said runners is set at an angle to the other, inclining together at their lower edges, as will be observed, with'a slight space, preferably about seven inches, intervening between the portions of the runners in advance of the cut-away or widened portions. Yokes B connect the two runners, and yokes C are also fastened to the yokes B, and their outer ends project beyond the sides of the runners and are provided with clodcrushers D. Braces E are fastened to said yokes carrying the clodcrushers and are also secured to the latter, while bracc rods E con nect the clod-crushers forwardmost of the yokes C with clod-crushers C similar to the clod-crushers D, before described, although the blades thereof are tilted at a different an gle and which clod-crushers C are mounted upon the rearmost yoke 0. Suitable clamps 0 hold the two yokes B and C securely together and allow the latter to be raised or lowered to adjust to deep or shallow listing.

F F designate brace-rods which are fas tened at their forward ends to the upper edges of the runners and'their rear ends to the rear yokes B and C, connecting the rear portions of the sled, and upon said rods a seat G is mounted, being adapted'to be held at different locations thereon, as may be desired. To the forward portions of the runners may be connected a tongue or other means whereby a team or horsemay be connected thereto. Each of said runners, at a location substantially at the longitudinal center thereof, is cut away, as'at H, allowing a considerable space to intervene between the rear portions of the runners and the portion of each runner intermediate the cut-away portion, and its rear end is widened and has a turning edge I, and adjustably mounted upon the outer face of each runner is a shield J, one end J of which is outwardly turned and set at an inclination, and the forward portion of each shield has transverse slots K,

through which the adjusting-screws K pass,

thereby affording means whereby the shields may be raised or lowered for the purpose of regulating the amount of dirt to be thrown,

thus making it positive in action and throw the desired amount of dirt at all times. By the inclined and outwardly-turned portion of the shield a cutting edge is afforded, whereby weeds may be out on the surface of the ridge between the furrows.

Fastened to the inner face of the widened portion of each runner is a steel plate N, the rear end of each being angled and provided with slots N, and N deslgnate screws fastened to the rear ends of the runners and passing through said slots, thereby affording means whereby said plates may be adjusted.

From the foregoing it will be observed that by the provision of the opening in the runners at the center thereof as the apparatus is drawn over a field dirt is allowed to come into the furrow before the sled has passed and by the peculiar-construction of the rear ends of the runners the latter will cut into the side of the ridge and push the dirt toward the corn and leave the wall of the furrow intact to guide the sled in next cultivation. By this detail dirt is brought in from the bottom of the ridge, and as it comes up beneath will have a tendency to straighten up the corn instead of crushing it down, as is the case when dirt is thrown from the top of the ridge, and when enough dirt is thrown to cover the corn the latter is left in upright position andwill soon appear again as the corn grows. By having the bevel cut on front end of runner clods are worked to side of furrow and crushed between sled and wall of furrow and not pushed in on the corn. By having the rear portions of the runners wider apart from the cut-away portions than at the front part of the sled any obstruction coming between the runners will ass out and will not be dragged along an crush down the corn, and

by the provision of the runners held at angles to each other the apparatus will hold to the furrow better than would be the case if the runners were perpendicular, and as the apparatus is dragged along the furrow with the inclined sides of the runners against the sides of the furrow the clod-crushers will level down the surface of the ridge, and the inclined portions of the clod-crushers will serve as weed-cutters to cut weeds along the surface of the ridge.

It will further be noted that by the construction of an appartaus embodying the features enumerated an apparatus is afiorded which will throw the dirt to the corn and leave a clean furrow, thus allowing cultivation to begin at any time and continue as often as desired until the corn is too high to be worked.

An apparatus for cultivating listed corn comprising runners which are set at angles to each other, yokes connecting said runners, clod-crushers secured to the projecting ends of said yokes, the rear portions of the runners being cut away, allowing a wider space between the runners at their rear ends than at their forward, and inclined cutting edges formed by the walls of said widened portion, as set forth.
