GEORGE F. KENNEDY,
PATENT OFFICE.
OF HOUSTON, TEXAS.
PLOW.
SPECIFICATION forming part of Letters Patent No. 279,252, dated June 12, 1883.
o, Application filed September 12, 1882. (Model) To all whom it may concern.-
Be it known that I, Gnonen FINLAY KEN- NEDY, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and use-' ful Improvements in Flows; 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.
My invention relates, generally, to the class of plows and the particular points of improve ment in my said invention are, first, the mold board, which, according to my invention, is made convex along its entire length, being made quite sharply convex at its front, where it joins the share, and with itstop and bottom edges'running in a straight line from front to rear, second, in combination with the moldboard made convex along its entire length and having a straight under edge, a landside, the shoe of which has a flange only along its inner edge, and which extends below the lower edge of the mold-board its entire length.
The object of my invention is to so construct and arrange the parts that a combined turningpl ow and subsoiler is the result, the plow being adapted particularly for use in heavy black land.
Referring to the drawings, forming apart of this application, and in which similar letters of reference indicate like parts, Figure 1. will be found to represent a side elevation on the mold-board side of aplow constructed according to my invention, Fig. 2, asection at 00 :10, Fig. 1; Fig. 3, a side elevation on the land side; Fig. 4, a detached view of the-share; Fig. 5, a plan view, and Fig. 6 an inverted plan.
A represents the plow-beam; B B, the haudles; G, the colter; D, the landside; E, the sole or shoe; F, the share or point, and G the mold-board.
The beam A is of the bent form, the front end being near the ground, then curving upward and rearward a slight distance, and then gradually curving downward again to near the end, and then again upward, where the handle B is secured. At the under side of the beam is formed a recess, A, into which the body of the plow is secured, the end of the plow-body resting against a shoulder, A", formed in the v beam and by the end of handle B. The rear end of the beam terminates in an upwardlybeyond the top end of the body, and to which the handle B is bolted, as shown at a (1?, Fig. 3. The opposite handle, B, is secured, as usual, to the end of the mold-board.
The landside D is of the usual or any approved construction. The shoe E is smooth 011 the landside and without the usual holding-flange, said flange being arranged 011 the inside, as at e Figs. 1, 2, 5, and 6.
The share F, Fig. 4, is made convex 011 its top surface and concave beneath, the bottom of the ci'itting-edge of the share forming an upward-curved line from the point f to the end f. The share at the landside increases in thickness from the point upward to the point where it joins the mold-board, and decreases in thickness and curves over from the la-ndside to the cutting-edge.
The mold-board G, instead of being of the usual concave form, is made convex on its outsidethat is, the mold-board is made to curve outward from the top edge, g, toward the center, 9, andthen inward from the center to the bottom edge, which edge is just above and only a slight distance from the holding-flange e of the shoe. The front or eolter edge of the mold-board is made concave in a vertical directionthat is, from the top edge, g, to the lower part, where the share joins it, and convex in a transverse direction, or from the cutting-edge g" to the lower edge, From the point (f, at the front edge, the mold-board curves gradually and only slightly outward until the point 9", Fig. 5, is reached,when the curvature takes a more decided outward curvature to the end of the mold-board. As will be seen by reference to Fig. 5, the top edge of the mold-board curves or bulges outward at its central portion, and by reference to Fig. 6 the bottom edge extends almost parallel with the shoe.
By reason of the peculiar shape given to the mold-board herein described the entire slice or piece of land cut by the plow is not turned over, while along the bottom of the furrow adjacent to the landside is formed, by the action of the shoe projecting below the moldboard and the shape and position of the lower curved tapered end, a, which projects upward edge of said mold-board, a furrow or channel.
Thus the plow partakes of the nature and coinbines the advantages of a subsoil and turning plow, for, by reason of the shape of said plow, at the same time that channels are formed below the surface, so much of the top surface as is necessary is turned over. By reason of the transverse curvature given to the share the bottom of the furrow is ridged or higher at the middle than at each side.
Having thus fully described my invention, its nature, objects, and advantages, what I claim as new, and desire to secure by Letters Patent of the United States, is-
1. In a plow, the mold-board G, made convex along its entire length, sharply convex at its front where it joins the share, and with its top 1 and bottom edges, running in a straight line from front to rear, as shown and described.
2. In aplow, the eornbination,withthe moldboard, convex along its entire length and having a straight under edge, of the landside I), the shoe E of which has a flange, 6, only along its inner edge, and which extends below the lower edge of the mold-board its entire length, as shown anddeseribed.
In testimony whereof I hereto affix my signature in presence of two witnesses.
GEORGE FINLAY KENNEDY.
