OF ALTON, ILLINOIS.

PLOW.

SPECIFICATION forming part of Letters Patent No. 250,151, dated November 29, 1881.

Application filed July 12, 1881. (No model.)

To all whom it may concern Be it known that I, JOHN LANE, of Hyde Park, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Plows, which improvement is fully set forth in the following specification and accompanying drawings.

Myinvention relates toimprovementsin plowbeams for use in plows throwing a furrow-slice both ways, called listing plows, and with which planting attachments and subsoil-plows may be combined; and the objects of my improvements are, first, to provide an extension or toe welded to the forward edge of the thinned and widened perpendicular foot of the beam, so constructed as to extend forward from the foot of the beam and form a seat at the forward end of the toe on which the listing-plow share is supported and bolted; and, second, to construct a heel part so as to provide a seat, to which a drill-tooth or subsoil-blade may be attached direct to the beam. I attain these objects by constructing the thinned and widened perpendicular foot end of the beam with a toe or bracket extending forward under the share, and with a heel or rear part of the foot of even thickness with straight sides and nearly perpendicular rear edge, as hereinafter set forth.

Figure 1 is a view, in perspective, of my improved plow-beam with a listing-plow share and a drill-tooth connected thereto. Fig. 2 is a view of the toe to as prepared for welding to the foot of the beam at the line m as, Fig. 1. Fig. 3 is a sectional view of the foot B with toe a, and also showing how the heel b is constructed.

Similarletters refer to similar parts throughout the several views.

The beam A is made of iron or steel and bent in the usual way. On the rear or bottom end of the beam I construct a foot, B, with a toe, a, extending forward, and with a rear part or heel, b, as shown in the drawings. In forming the foot 13, I widen the foot end of the beam by thinning it down with hammers to a thickness of about one-third of its original thickness, and the rear edge for about five inches high I make of an even thickness of about onehalf inch, with straight sides and nearly perpendicular edge, forming the heel b, as shown in the drawings in Fig. 3. I first prepare the toe a and the footB separately, and afterward I weld the toe a to the forward edge of the thinned and widened perpendicular foot B, as shown in the drawings in Fig. 3. The forward end of the toe is bent down, widened, and perforated to fit the underside of a listing-plow share, as shown in the drawings, Fig. 2, after which the toe a and foot B are heated to a welding-heat and the two united together at about the line as w.

F is a listing-plow share, attached to the too a with a bolt, g, as shown in Fig. 1.

O is a drill-tooth shank, having a groove, '5, embracing the sides of the heel b, and held in a set position by the eyebolts 70, having screwnuts on their rear ends bearing against bar 6. The eyebolts It have a bolt through their eyes and the beam at n.

The foot B is made wide and thin perpendicularly, and connects the toe a and heel bin one solid piece, by which there is no place for trash to gather between the share F and tooth G. I prefer to set the bottom of the foot B about two and a half inches above the bottom of the furrow, that the drill-tooth may have room to lift its furrow without hinderance of the foot.

It is common to construct plow-beams with a wide foot, to which parts landside bar and braces are bolted, and such I do not claim; and I do not claim, broadly, a bent beam having its bottom end bent so as to extend under the share.

In operation, the toe a, widened and perforated, provides for a rigid foundation-support to the share, and the heel 1) provides for attachment of drill-teeth or subsoil-blades direct to the beam in a simple, easy, and substantial manner, and the drill-tooth may be readily adjusted up or down by a movement of the groove i on the heel b by'looseuing the screw-nuts on the rear end of the eyebolts 70.

Instead of drill-teeth, a subsoil attachment may be attached as the drill-tooth and adjusted to any desired depth below the share F.

Having thus described and set forth my invention, what I claim, and desire to secure by Letters Patent, is-- 1. The combination, with a bent plow-beam, A, having a thinned and widened perpendicular foot, B, of the extension or toe a, constructed to extend forward from the foot of the beam ened foot B, and having the heel 12 formed on 10 and provide a seaton which the share is supthe rear edge of the foot B, as shown, in comported, substantially as and for the purpose bination with the tooth O, the eyebolts 70 k, and.

set forth. the bar 0, substantially as and for the purpose 5 2. The combination, with a bent plow-beam set forth.
