CONVERTIBLE PLOW.

BPECIFICATION forming part: of Letters Patent 310310333,

Application iiled August '27, i884,

Beit known that I, HENRY D. TnRanLL, of Govington, in the county of Newton and State of Georgia, haveinventedanew and Improved Convertible Flow, of which the following is a full, clear, and exact description.

The object of my invention is to lessen the outlay required for agricultural implements, and iorkeepingthem in working order,thcreby promoting the more economical cultivation of the soil for a variety of crops.

The invention consists in a convertible plow made with a foot plate or piece having edge flanges, and an oiiset shouldered end allowing the attachment thereto of interchangeable side plates or wings and plow-points of various kinds, so as to form, as required for use, a scooter or bull-nose plow, a turningploma shovel-plow, and a scraper-plow; and also permitting small or short plow-points to be used, and to be renewed when worn.

The invention consists, also, in particular constructions of the plow foot -plate and of the several interchangeable mold-boards and wings for connecting them by bolts. so as to be securely held and readily removed; and also in particular combinations of the interchangeable mold-boards and wings and plow-points, all as hereinafter fully described and claimed.

Reference is to be had to the accon'ipanying drawings, forming part of this specification, in which similar letters ofreference indicate corresponding parts in all the figures.

Figure 1 is a perspective View of the lower end of a plow stock with my improvements attached as a turning-plow. Fig. 2 is a perspective View showing the arrangement of the parts as a shovel plow. Fig. 3 shows the parts arranged for a scraper-plow. Fig. 4 is an enlarged longitudinal sectional elevation on the liner m, Fig. 3. Fig. 5 is a perspective View of the turn-plow 1nold-board, and Fig. 6 is a perspective view of one of the wings or side plates of the shovelplow.

The letter A indicates the foot-plate or scooter-body, which is to be held to any suitable plow stock or standard B-partly shown in Fig. 1-by a strong bolt, 0, passed through the stock and receiving a nut at the back of the stock, and the tapered head of the bolt. enters a correspondingly-shaped recess, 0, in

the foot'plate A, so as to draw the plate firmly to the stock and be flush with the face of the plate, to avoid catching the earth which may rise to it when the plow is at work, and the top of the foot-plate comes against the usual shoulder, (1, ofthe stock to steady the plate, so that one bolt. C, will hold it firmly without lateral play. At each edge the foot -plate A has a backwardlyextending fiange, D, which has lugs (Z, provided with suitable holes, (2, for the passage of bolts by which to secure to one or both edges of the foot-plate the interchangeable wings or mold-boards, as hereinafter more fully explained. I make a backward offset in the face of the foot-plate, near the bottom, for about the thickness of the interchangeable plow-poi nts, as at E, and I undercut the shoulder of said offset or recess, as at a, so that the correspondingly inclined or beveled top edges of the plow-points will look into and under the shoulder, for allowing the points to be held firmly to the foot-piece by a single bolt, F, the head of which is countersunk into the plowpoints, as shown in Fig. at, to allow the earth i'ree passage over the face of the plow and prevent wearing away of the head of the bolt. The pointless foot-plate A is bolted to the stock 13, so as to have the same set as the ordinary scooter'plow plate, and so as to receive any desired shape of plow-point-such as a scooter-point made in the shape of the lower ends of the ordinary scooter plow shares, such as may be represented by so much of the plow-point in Fig. 1 as corresponds to the width of the f0ot-piece Aor an ordinary double-curved bull-nose plow-point, such as is represented in Fig. 3, may be connected to the foot-plate by the bolt F.

The letter G- indicates a mold-board which has a flange, 9, provided with holes 9 for the passage of bolts through them, and the upper and lower holes (1 at one side flange of the foot-plate A; and G is a broad plow -point, fitted to the offset E- and shoulder c, and held by a bolt, F, below the plate and the mold board, so that the parts A G G constitute together an eiiicient turning-plow, as in Fig. 1.

The letters H H indicate side plates, which have flanges h with bolt-holes h, as shown in Fig. 6, said plates being made in pairs, so as to be bolted to the flanges D of the foot-plate A at each side of it; and II is a broad shovelpoint, fitted to the offset and shoulder E 0, fastened by a bolt, F, and abutting the lower ends of the side plates, H H, as in Fig. 2, for converting the plow into'a shovel-plow.

The letters I I indicate scraper wings or blades, which have upwardly or outwardly turned flanges z i, ranging obliquely at the bendto the front cutting-edges, j, of the scraper, so that said edges incline backward suitably for working easily through the soil; and the flanges i 7; will be bent upward or outward from the faces of the scrapenblades at varying angles with their faces, to incline the pposite scrapers more or less to the face of the foot-plate A, as the nature of the soil shall require. In stiff land the angle of inclina tion will not be so great, or will be more obtuse, so that the soil can pass off easily, while for use in gray or sandy soil the angle of inclination will be more acute, or nearer a right angle.

By providing the flanges D D of the footplate A with three bolt-holes, d, as shown, I am enabled to fasten the opposite scraper blades, I Lby the nutted bolts 7c,passed through the bolt-holes of flanges 2' either into the two upper holes, cl, of said flanges D, for holding the bladesI I at the top of the foot-piece A at each side, as in full lines in Fig. 8, for deep plowing, or the fastening -bolts may pass through the flanges into the two lower holes, (1, of the flanges D,to hold the scraper-blades in the positions shown in dotted lines in Fig. 3, or nearer the plow-point, for shallow plowing, as will readily be understood.

I show in Fig.3 the bullnose plow-point I, fastened by the bolt F in the offset E and against the shoulder 6; but the wider shovelplow point II shown in Fig. 2 may be used with the scraper I I, if desired. \Vhenthe plow-points are madeintegral or in one piece with the main body of the scooter'plow plate in the common way, the entire plate becomes useless for plowing purposes when but onethird of its length is worn away at the lower end; hence, by providing the foot piece or plate A and attaching separate plow-points thereto,when the point is almost wholly worn. away it may be removed easily by taking out the bolt F, and a new point quickly be substituted, and one of the foot-plates Awill outlast many of the points, which may be interchanged one for the other as the work shall require,and, as the points made as I propose will cost very muchless than an entire plow-plate, a considerable saving in the cost of the plowplates is secured; and by my method of fastening the removable points with an undercut or looking shoulder in connection with the fastening-bolt quite as strong an implement is provided as one made in a single piece; and by providing the foot-bolt A with the apertured flanges D D, permitting a variety of mold-boards and plow-plates to be attached to it, fewer agricultural implements as a whole will be required; hence the soil may thoroughly be cultivated for a variety of crops at less expense.

I prefer to make the foot-plate A and the interchangeable points and side plates or wings in malleable-iron castings,but they may be made of other cast or wrought metal,as desired.

Having thus described myinvention, whatI claim as new, and desire to secure by Letters Patent, is-

1. As an improved article of manufacture, the foot-plate A, formed with the apertured offset E, having undercut shoulder e, and with the backwardlyextending edge-flanges D, hav ing apertures d, as set forth.

The combination, with the foot-plate A, formed with the apertured offset E and the apertured edge-flanges D, of an interchangeable point and flanged wing, whereby various forms of points and wings are adapted to be secured to the offset and flanges of the foot plate, substantially as herein shown and de scribed.

3. The combination, with the fo.ot-plate A, formed with the apertured offset E and the apertured edge-flanges D, of the'mold-board G, provided with the apertured flange g g, and the point G, secured in the said offset, substantially as herein shown and described.
