REVERSIBLE, HILLSIDE TURNING rrow.

To It? what/L it mayco'hccrn:

Be it known that' l, Sriirson Learns, a citizen of theUnited States, and a vresident of Primrose,'in the county ofLee and State of Kentucky, have invented certain new and useful Improvements in Reversible Hillside Turning flows, of which the following is a specification. A

This invention relates to plows and more particularly to a hillside turning plow, and the primary object of the inventionis comprehended in the provision ot'a plow of the class described, by which adjustment may be secured for the point, andbetween the point and the 'moldboard, in order that the point may be adjusted to wear, being thereby adapted to beheld in different positions so that only the extreme forward portionof the point will engage the "ground and {be subject to wear, "and may be maintained inline with i the land bar or runner at all times, thereby producing an eifective hillside turning plow,- as well as insuring proper engagement with and turning of'lthe earth, in addition to pro longing the'life of'the point. Y

A further object of the invention is to obviate the objections existent in the old types of -plows in which'the plow point at theportionthereof-from the end of the frog to the'end 'of'the point is arranged to contact with theground and is therefore subject to wear, with t'he resultthat the bottom of the point wears all along,"between the frog and theextreme end of the point, thus necessitating constant renewals of the points at considerable-expense, and subjecting the otherparts to unnecessary wear, as well as interfering with the plowing action, the present inventionproviding novel means forv adj 'ustments of the point angularly up and down, so'that the heel may be maintained out of contact with respect to the ground and lowered as the point wears, so that the point will less abrupt bend from the frog than plows inwhich :the points are not adjustable, so-

as to shed the soilbetter andnot to take too much land in use, thepoint remaining sharpenedas well as the shears orside edges of thQPOiIl-t- I I last for'a somewhat in-c i SpecificationcfLetters Patent. v Patenfed Feb 14, 1922 Application filed J'u1y 22,'1920. "serial No. 398,671. d

Other and further objects of my invention will become readily apparent to persons skilled in the art, from a consideration of the following description when taken in conjunction with the accompanying drawings, wherein: H

vFigure 1 is a side elevation of a hillside turning plow constructed in accordance with the invention, w

Figure 2 is an opposite side elevation thereof, 5

Figure 3 is an enlarged central longitudi nal'sectional view. through the plow point and moldboard, the handles, beam or stock and standard being omitted, i j Figure .1- is a rear elevation of the device as shown in Figure 3, for operating at either 'Figureo is a sectional view taken on the linej5'5 of Figure 3, i 7' i Figure 6 isan enlarged detail perspective view of the frog shield,

' Figure 71-is a perspective view of one of plate connecting with or forming a part of the landbar or runner 15 pivoted for turning movement as indicated at 16, in the lower end and forward face of the standard 17, which extends upwardly and forwardly and is secured as indicated at 18, to the moldboard' 19 intermediately of the sides and near the rear end of the latter. The securing means may be in the form of a screw, bolt or otherwise as is common in this art,-

and it is also to be understood that the beam,

handles, braces and stock, aswell as the standards, may be of any ordinary or well known construction inlieu of that above described and shown in thedrawings.

The moldboard 19 is preferably tapered slightly toward its rear end and rounded, while the forward end thereof extending from the parallel sides is offset downwardly as indicated at 20 and formed with a tapered forwardfend .21 extending to a point equiing beveled side edges as shown. The forward end of the land bar or runner'15ispivotally engaged. as indicated at 22in the depending triangular extension 23'form1ng the base frog which projects at either side of the strip 2% "forming apart thereof and near the forward end ofwhicli it is disposed. The frog extends in alinemen't with the land bar 15 and an inclined position above the same, ,the rear end of the strip 2i being bent upwardly when applied and connected to the moldboard 19 through the medium of a connecting, bolt or the like 25 which also serves for the connection of the apertured forward end of a brace 26 with the stock or shank 1-7, the latter being apertured horizontally for this purpose, preferably at right angles tothe length thereof, in order to brace the frog and inoldboard in position, as well as hes anda oi the moldboard. is the plow share or point 27, the same being of slightly concaved or angular cross section, particularlyat the apex or point thereof, said plow share or point proper being preferably of triangular tormation, The sides adjacent to the point are also sharpened in ordertoprovide shearing edges, as indicated at 28, to facilitate cutting and plowing in sprout-y ground, or inv stubbles. A plurality, preferably a pair,

. oil wedges, wedge plates or the like 29, and

30 ,of I substantially triangular outline with beveled edges and tapering in thickness towardtheir rear edges are disposedbetween the substantially fiat intermediate portion of the point and the offset portion 21 ,so as to extend to the heel of the point at ,the shoulder providedat-said ofi'set portion 20, and, are detachably but firmly secured through the forward portion oi the frog as through the medium of a bolt 31, the head thereof being embedded; in the point and the securing nut and washer-being exposed at the bottom where it is readily accessible for renewal, adjustment or repair.

However, in order to protect the bolt and frog, a frog shield 32 is provided, the same being preferably cast, while the base frog is preferably of'malleable iron. The shield is tapered to a point, being substantially triangular and hollowed out at the top, the sides being beveled to conform to the edges of, the wedges, frog and cut sides of the plow shareorpoint and; having rearward exten sions or furcations 32' extendedrearwardly and made relatively thin, so as to engage between the wedge plates or tapered forward end 21 ,of the moldboard andthle projecting sides ,ogtthe base frog in contact with the bottom face of said moldboard extension so as to straddle thefrog Qtat' either side, thus locking the partsiin position firmly, in con-,

Arranged above the offset end portion 21 of securing bolts 33 also extendin through I the intermediate portion of the p ow share or point-near the 'heel thereof, through the wedge plates, moldboard extension immediately'forwar'dly of the offset portion or shoulder 20 and a brace or strip 34, which straddles the rearwardly extending portion of the base frog, By this means, the parts are securely held together, and the plow share orpoint, together with the moldboard,

may swing at eitherside of the stock. as-

bar or runner. In thisway,,the pointtwill" be prevented firom wearing 'from'one end of the frog toone endof the point by reasonof the tact that the rear portion orhee l o fthe point will beinaintained out oficonbe very small, instead of the heel Of he: plow being abruptlybent with respect to, the forward portion thereofso that proper engagement with the ground surface may result. Thus, the renewal'of the -,inside:point is obriatedland the an 1e of'the disposition of the; point may be the thicknesses of the Wedgesywhich latter maybe added or removed so as. to keep the end of theipointjn line withthela nd bar as the point wears, sothat a straight line C011,

The forward bolt may then be loosened, and by removingthe point and corresponding wedge plates, angu lar adjustment of the point may be secured. When a new point is inserted after the first one is worn out, the wedge plates are re placed as previously.

Having thus described my invention, what I claim is l. A hillside turning plow comprising the combination with the beam, handles braced thereto, a stock, a land bar at the lower end of the stock and standard in which the rear end of the land bar is pivoted; of a moldboard attached to the upper end of the standard and having a tapered offset) forward end, a, frog secured to the moldboard and having a projection in which the forward end of the land bar is pivoted, a point of relatively angular cross section having its forward portion substantially in alinement with the intermediate and rear portion dis.- posed against the moldboard, displaceable rearwardly tapering wedges between the moldboard and point, a frog shield over the forward portion of the frog, securing means between the frog and point, and means connecting the guard with the point through the moldboard and wedge plates at the heel of the point.
