Serial No. 487,539.
To all whom it may concern:
Be it known that I, WILLIAM A. Srnrnnns, a citizen of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented new and useful Improvements in Subsoiler Attachments for Plows, of which the following is a specification.
This invention relates to improvements in plows, particularly with reference to a subsoiler attachment to be used in connection with an ordinary turning plow for the purpose of sub-soiling in the bottom of the furrows, and the said invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.
In the accompanying drawing: Figure 1 is a perspective of a plow provided with an improved sub-soiler attachment constructed in accordance with my invention. Fig. 2 is a detail elevation.
The plow indicated at 1 is here shown as an ordinary turning plow and may be of any suitable construction. In accordance with my invention, I provide plates 2, 3, which are secured respectively on the upper and lower side of the plow beam 4 at a suitable point. The said plates are here shown as bolted in place and provided with bends 5 which form notches 6 between the said bends. To the rear end of the plow beam is pivoted to tension the spring and to adjust the subsoiling standard.
It will be apparent from the foregoing description and reference to the drawing that the sub-soiler attachment which is disosed in rear of the plow share 17 operates in the bottom of the furrow directly behind the share so that it serves to thoroughly stir and loosen the sub-soil and without bringing it out to the surface and exposing it to the elements, since the sub-soil thus stirred by the sub-soiler is covered by the mold overturned in the making of the next adjacent furrow.
In Fig. 2 of the drawings, I show a supplemental beam 28 which is employed in connection with the ordinary plow beam when the latter does not extend rearwardly of the standard a suflicient distance to enable my improved sub-soiling attachment to be fixed to the beam. The said supplemental beam serves to carry the sub-soiling attachment, the latter being pivoted thereto and said supplemental beam is secured in place on the beam of the plow by means of stirrups 18 which are engaged with appropriate notches of the upper and lower plates 2, 3, and extend around the beam and the supplemental beam. hen the sub-soiler is in use with a plow the spring 15, which is of considerable strength, under normal condi tions holds the sub-soiler to its work, but should the sub-soiler encounter an unyielding obstruction, such as a stone or root, the spring enables the sub-soiler to yield and hence prevents it from being broken.
hat is claimed is:
1. A turning plow having a beam and a turning share and also having a sub-soiler comprising a standard pivotally connected to the rear end of the beam and disposed in rear of and extending below the turning share, a brace rod connected to the subsoiler standard for movement of the latter on said brace rod, means connecting the front end of the brace rod to the beam for adjustment longitudinally of the latter, and a spring on the brace rod in rear of the subsoiler standard and bearing against the latter.
2. A plow having a beam and a turning share, adjusting plates on the upper and lower sides of the beam slightly in advance of the standard of the turning share, said adjusting plates having notches, and a sub- 8, said sub-soiling standard having near its upper end a series of adjusting openings 9 with any one of which the said pivotal bolt may be engaged. A sub-soiling point, plate or tongue 10 is secured to the lower end of the sub-soiling standard and the latter is provided at a suitable distance from its lower end with an opening 11 through which extends a brace rod 12, the said sub-soiling standard being movable on said brace rod. The latter has a hook 13 at its forward end engaged with a link or stirrup 14 which link or stirrup passes over the plow beam transversely and has its upper end engaged with one of the notches in the upper plate 2 at an appropriate point according to the angle at which it is desired to operate the sub-soiler. On the rear end portion of the brace rod 12 is a coil extensile spring 15 which bears between the rear side of the sub-soiling standard and a nut 16 which is secured on the rear end of said brace rod and which serves soiler attachment comprising a standard pivotally connected to the rear end of the beam in rear of the turning share and extending below the turning share, a subsoiling point at the lower end of the said sub-soiler standard, a link connected to and adjustable on the said plates, a brace rod connected to the said link and also connected to the sub-soiler standard for movement of the latter on said brace rod and angularly with respect to the beam, and a spring between the said sub-soiler standard and the brace rod and yield when the same encounters an obstruction. 15 In testimony whereof I aflix my signature in presence of two witnesses.
allowing said sub-soiler to WILLIAM A. STEPHENS.
