SPECIFICATION forming part of Letters Patent No. 733,761, dated July 14, 1903.

Application filed December 27, 1902. Serial No. 136,795. (No model.)

To all whom it may concern:

Be it known that I, ALVA G. STEELE, a citizen of the United States, residing at Pidcock, in the county of Brooks and State of Georgia, have invented certain new and useful Improvements in Plows, of which the following is a specification.

In the type of plow in which the share is secured to the bifurcated standard I have combined a surface-soil-turning wing of peculiar set-back shouldered construction located and fastened at theleft edge of the share between it and the standard and secured by the nutted bolt, by which the share is fastened to the standard, and thereby adapt the plow to do the work hitherto done by two separate innto the right the siding-wing will give a sur face turn of the soil at the left, the two kinds of work will thereby be done at the same run.

The accompanying drawings show in Figure 1 a shovel-plow with a surface-turning wing shouldered to form a bearing on the front and on the side of the. standard. Fig. 2 is a like view, the share being removed to show the position of the surface-soil-turning wing as it is bound by its twist-formed shoulder or setback upon the bifurcated bars of the standard. Fig. 3 shows the wing and its twisted or set-back shoulder-forming end. 1

The standard is bifurcated and its bars 1 l are secured to the beam, while the share 2 is fastened by the bolt 3 passing between the standard-bars and nutted on the rear side of the latter in the usual way. The share is of the form which when fastened in place projects to the right, so that its left edge is along the standard and its fastening-bolt is near its upper edge, and at this point the sidingwing t is attached and braced. The wingis a plate about ten inches long and three inches wide and has its angle end twisted slightly backward at 9 from its cutting edge and given an oblique-anglebend at such twist, adapting it thereby to be seated upon and across the front and against the side of the standard, so that its blade will extend to the left thereof and obliquely backward, bringing its upper edge about on a level with the upper edge of the share, but standing backslightly by reason of its twist or set back from the edge of share, so that the lower cutting edge of the wing will give a scraping siding action over the surface. The Wing thus placed upon .the standard, the share is placed upon the bent end of the wing,'and both the share and the wing are secured by the nutted bolt, binding both parts firmly upon the standard. The twisting of the end of the wing gives it a shoulder formation 5 atits upper thick edge, Fig. 3, so that in seating the wing this shoulder will abut against the side of the standard, and thereby support the wing against the standa rd, the bolt serving to bind the share and the wing upon the standard. By this construction both the share and the standard cooperate to give a firm seating and support to the wing, the shoulder 5 of which is made by bending and twisting the end ofthe wing in two directions, one fiatwise less than a right angle to give the seating of the wing upon and across the front side of the standard, and the other edgewise to give the shoulder 5 to support the wing against the side of the standard.

From its cutting edge to its point the wing decreases in width, giving thereby an oblique cutting edge, while at its upper edge the point 6 is made concave on its upper surface to give a better turning of the soil.

While I prefer to use my improvement with the bifurcated standard, obviously other forms of standards may be used. I

For certain conditions of soil and of the cropas, for instance, a young crop and smooth soil-the wing should be run shallow; but with rough soil and older crop the wing should be run deeper. To suit these conditions, the wing is provided with a slot 7, through which the bolt 3 passes, so that the wing can be set up or down in relation to the top of the shovel, and this is rendered convenient by loosening the nutted bolt which secures the shovel.

The wing stands obliquely to the path of the plow, so as to turn and push the soil toward the row of plants, and as this action puts on the Wing, a heavy lateral pressure it is the function of the twisted shoulder or setback supported against the side of the standard to resist this lateral pressure.

I claim- 1. In a plow the standard, the shovel, the surface-soil-turning Wing having an angle end and a setback at its upper edge forming a shoulder joining the angle end whereby the latter is supported across the front and against the side of the standard, and the nutted fastening-bolt.

2. In a plow and in combination with the standard and the shovel, a surface-soiLturning wing having its end bent at an angle, its upper edge twisted or set back flatwiseforming a shoulder joining the angle and standing back from the angle end whereby the wing is supported on'the front and against the side of the standard, and a securing-bolt common to the shovel and to the Wing.

In testimony whereof I affix my signature in presence of two witnesses.

ALVA G. STEELE.
