SUBSOIL-PLOW.

Specification of Letters Patent.

Patented Sept. 26, 1911.

Application filed. January 20, 1911. Serial No. 603,723.

To all whom it may concern:

Be it known that I, JAMES M. Bnoons, a citizen of the United States of America, and a resident of Molena, county of Pike, State of Georgia, have invented certain new and useful Improvements in subsoil-Flows, of which the following is a full and clear spccification, reference being had to the accompanying drawings, in which-- Figure 1 is a side elevation of a plow embodying my improvements; Fig. 2 is a horizontal section on the line 22 of Fig. 1; Fig. 3 a detail perspective view of the plow shank or standard, the plow share and landside bar being removed; Fig. l a perspective view showing a modification; Fig. 5 a perspective view showing a detail of the afore- Fig. 6 is a vertical sec tional view of the modification shown in Fig. 4.

The object of the present invention is to provide a subsoil plow which shall be simple and inexpensive in construction as well as durable and eflicient in operation; and this invention consists of certain novel features of construction hereinafter described and claimed.

The plow shank or standard a consists of a wide flat. plate of sheet metal having its front edge somewhat sharpened and having its upper end suitably attached rigidly to the plow beam. The lower end of this plate a is slitted vertically near its rear edge and also near its forward edge and the portion of the metal between these slits is bent to one side to form a seat I) for the plow shovel or scooter. The end portions depend below the seat Z) to form lugs or ears 0 to which are bolted, on the landside, a landside bar (Z which inclines slightly upwardly and backwardly and is beveled off downwardly at its front end to form an entering point c, this entering point being wider than the main or rear part of the bar and being shouldered at f to abut against the forward edge of the plow shank a.

The seat I) inclines upwardly and rearwardly to give the proper inclination to the scooter or shovel g which is clamped down on its upper face by a bolt It, the scooter or shovel being provided with a longitudinal slot 2' to provide for adjustment of the scooter or shovel to enable the same to be located properly with respect to the entering point of the landside and to compensate for wear of the shovel or scooter. The seat 6 is slightly curved longitudinally so that when the scooter is clamped thereto there will be a slight resilient action, this being advantageous in that it will render unlikely the stripping of the threads of the bolt by excessive clamping action.

In the construction shown in Figs. 4: and 5, I provide for a double plow, that is, a plow in which a scooter or shovel may be supported at each side of the plow shank. This is accomplished by riveting to the plow shank an additional plate 7' of sheet metal and providing the same with a supplemental plow seat 70, similar in shape and arranged directly opposite to the main seat 6. Depending ears Z on this plate j correspond with the depending ears 0 on the main shank. This plate j has its depending edge bent outwardly, and the lower portion of the main part of the shank is similarly bent outwardly, thus forming a channel for the reception of the landside bar cl, this bar being fastened between the plates by suitable horizontal bolts 01. and the head of this bar being shouldered upon opposite sides to abut against the forward edges of the front ears 0 and Z.

It will be observed that my construction enables the plow to be constructed of a very few parts which may be readily assembled and which will be strong and durable.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A sub-soil plow, consisting of a beam,

a depending flat sheet metal shank or standard slitted vertically at its lower end at points at a distance from its forward and its rear edge, the portion of the shank between the slits being bent laterally and inclined upwardly and rearwardly, thus forming a plow seat I; and two depending ears 0 integral with the shank, a plow blade fastencd to 'said plate I) and abutting against the adjacent side of the shank, and a landside bar fastened to the depending ears 0 at the side of the shank opposite the plow and having its lower edge below the plate I) and co-incident with the lower ends of the ears 0, this land-side having its forward end pointed and enlarged laterally, this enlargement forming a vertical shoulder which abuts against the front edge of the front ear.

2. A sub-soil plow, consisting of a beam, a depending flat sheet metal shank or standard slitted vertically at its lower end at points at a distance from its forward and its rear edge, the portion of the shank between the slits being bent laterally and inclined upwardly and rearwardly, thus forming a plow seat I) and two depending ears 0 integral with the shank, a plow blade fastened to said plate 6 and abutting against the adjacent side of the shank, the shank being bent laterally at a point above the slits to off-set the plow supporting plate 6, a supplemental plate fastened to the shank at a point above the land-side bar and provided with depending ears Z and an integral plow supporting plate is similar to the aforesaid plate 7), and a land side bar clamped rigidly between the ears of the shank and the ears of the supplemental plate and having their lateral shoulders at its entering point which I abut against the front ones of said ears.

In testimony whereof I hereunto afliX my signature in the presence of two witnesses this 17 day of Jan. 1911.

JAMES M. BROOKS.
