PLOW.

Specification a Letters Patent.

Patented Aug. 25, 1914.

Application filed. April 30, 1913. Serial No. 764,722.

To all whom it may concern:

Be it known that I, ELI W. HOLLINGS: women, a, citizen of the United States, residing at Zirconia, in the county of Henderson and State of North Carolina, have in, vented certain new and useful Improve: ments in Flows, of which the following is a specification.

My invention relates to plows, and more particularly to reversible plows.

One of the objects of the invention is to provide a device of the character described comprising pivoted standards, each of which is equi ped with the component parts of a plow, whereby either standard is adapted to be swung into position to throw the dirt to the right or the left, as desired.

Another object of my invention is to provide a plow in which the standards are adapted to be folded, thereby insuring the maximum compactness in storing and transportation, and permitting of the inactive plow to be adjusted so as not to interfere with the vision of the attendant.

A further object of the invention is to provide means for maintaining the plow standards against lateral displacement when inactive.

' A still further object of the invention is to provide common means for simultaneously adjusting the landside and moldboard of the low.

P To the accomplishment of the recited objects and others coordinate therewith, the preferred embodiment of my invention resides in that construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and embraced within the scope of the appended claims.

In said drawings :F igure 1 is a side elevation of the plow embodying my invention, and Fig. 2 is a top plan view thereof; Fig. 3 is a transverse sectional view taken upon lines 33 of Fig. 1, and Fig. 4 is a similar view taken along lines ll of Fig. 1

Generally speaking, my invention comprises a beam suitably connected at its rear end to the conventional type of handle, the said beam being adapted to receive at a point adjacent its rear extremity a sleeve provided with oppositely arranged stocks, Each stock has pivoted thereto a standard, which in turn carries the plow parts, the said standards having springs which are designed for engagement with appropriate recesses in the stocks to permit of sustaining the standards in a substantially vertical position when in use. Furthermore, the butt of the stock is provided with a notched flange designed to be engaged by a suitable latch for locking the stock and its adjuncts in the desired position. I have also included a novel form of plow, in which the landside and moldboard may be simultaneously ad usted by the proper manipulation of a single heel-bolt.

In said drawing, 1 designates the beam having an elongated head portion 2 to which the lower extremity of the handle 3 is connected. The beam is preferably cylindrical and has a sleeve 4 mounted thereupon for rotatable movement, the said sleeve being provided at its rear end with oppositely disposed stoclrs or projections 5, which are partially hollow in order to permit of pivoting the inner terminals of the standards 6, as at 7. The rear wall of each stock, at a point adjacent its outer extremity is provided with a recess 8, and this recess is intended to be engaged by the angular end 9 of the leaf spring 10 secured to the medial portion of each standard. Furthermore, an annular flange as 11, is constructed as an integral part of the sleeve 4, and at diametrically opposite points of this flange there is arranged a notch 12, which cooperates with the spring latch 13 mounted upon the upper face of the enlarged head 2 of the beam.

In order to counteract any tendency of the standards becoming laterally displaced when they are folded inwardly toward the beam 1 I employ a collar 14. which is mounted against the outer end of the sleeve 4, and carries an upwardly projecting bifurcation or yoke 15. The lower extremity of each standard has an elongated slot 16 while the landside 17 is provided with an angular extension 18 so that the landside and moldboard may be held firmly against the outer face of the standard by means of a single heel-bolt 19. This arrangement permits of relative adjustment of the landside and moldboard, as will be presently set forth. It will also be noted that one standard carries a right hand plow and the other standard aleft hand plow, this obviously being for the purpose of accomplishing hill-side plowing without subsoiling.

In practical operation, the plow is adjusted as clearly shown in Fig. 1 of the drawings, that is to say, the left hand plow and its standard are swung outwardly to cause the angular extremity 9 of the spring to engage the complemental recess 8 of its adjacent stock, while the opposite standard and plow are constrained downwardly toward the beam 1, the central portion of the standard occupying a position between the bifurcation l5. Vl ith the parts in positions just explained the attendant may operate the implement until such a time as he desires to utilize the left hand plow, when it is simply necessary to grasp the upper standard 6 and pull it toward the handle 3 until the spring 10 falls in the notch 8 of the stock. Then by releasing the spring latch trom engagement with the notch 12 in the annular flange 11, the stock and sta dard, as an entirety, may be rotated until the opposite notch is in line with said latch, whereupon the parts are again locked. Subsequently, the angular extremity 9 of the spring 10 of the upper standard is disengaged from the notch S and the said standard forced between the bifurcation 15.

lvianifestly, it will be understood that any desired adjustments of the land side and moldboard can be made with facility by loosening toe heel-bolt 19 and moving these parts either longitudinally of the standard or at right angles thereto, and then tightening the bolt.

With the inactive standard and plow lying in close proximity to the beam 1, and in substantially the same plane, it will be seen that the vision of the attendant is in no way obscured. I consider this an extremely important advantage over similar plows wherein the uprights are rigidly connected to a central sleeve and occupy a minimum space and thus greatly facilitate and transportation.

ther inherent advantages secured by the use of my plow are that a land can be plowed smooth to one side without leaving a trench in the soil; that when listing the soil the middle can be thrown at one furrow to each row without the use of a middle-burster; and that when plowing hill or sloping land, the land can be plowed up hill or the levee thrown on the hill-side to prevent washing of the soil. To accomplish all of these results it is merely necessary to rotate the sleeve 4 upon the beam 1 to bring the desired plow into operation.

It should be understood that in its broader aspect the invention comprehends the employment not only of the various means described, but of equivalent means for performing the recited functions.

While the arrangement shown is thought at the present time to be perferable, it is desired to reserve the right to efiect such modifications and variations thereof as may come fairly within the scope of the appended claims.

What is claimed, is

1. In a reversible plow, a beam, a sleeve rotatable thereon, standards foldably mounted upon said sleeve, means for holding said sleeve with one of said standards in operative position, and means holding such standard against movement upon its pivot when in such operative position.

2. In a reversible plow, a beam, a sleeve rotatable thereon, standards foldably mounted upon said sleeve, means for holding said sleeve with one of said standards in operative position, means holding such standard against movement upon its pivot when in such operative position and means on said sleeve for detachably receiving the other standard when in its foloed inoperative position above the beam and out of the line of vision of the operator.

3. In a reversible plow, a beam, a sleeve rotatably mounted thereon and provided at its rear end with oppositely disposed pro-v jections each having a recess, oppositely disposed standards independently pivoted on said projections and each carrying a plow, means for holding said sleeve against rot: tion with either of said standards ex ended downwardly, a spring mounted on each standard and having an angular portion to engage its corresponding recess and means on the sleeve to receive the uppermost standarc when folded and hold it out of the line of vision of the operator.

l. in a reversible plow, a beam, a sleeve freely rotatable thereon, means for automatically locking said sleeve in adjusted position, standards pivotally mounted at diametrically opposite points on said sleeve, means for automatically locking each standard to the sleeve in its depending operative position, and means on the beam independent of said sleeve and bearing againstthe end thereof to receive the inoperative standard folded substantially parallel with the beam.

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