This invention relates to plows andfmore especially relates toV a reversible or hillside plow. 'y

One important object of the invention is to provide an improved general arrangement of devices 4of this character.

A second important object of the invention is to provide improved share supporting and reversing means for such a plow.

' A third important object of the invention is to provide a novel arrangement of locking means for holding the share set in its desired position. Y f

A fourth important object of is to provide a novel share arrangementfor such a plow, the share being equipped with rotary means for assisting in turning the earth.`

A fifth important object ofthe'invention is to provide an improved share for such a plow so arranged that it has four cutting edges arranged in pairs and supported so that either of the plow. l With the above and other objects in view, the invention consists in 'general of certain novel details of construction and combina-r tions of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings, like char` parts in the acters of reference indicate like several `vlews, and

Figure 1 is a side elevation ofthel plow" with the share thrown to the right;

Figure 2 is a similar view with the share to the left; y Figure 3 is a plan view with the ranged as in Figure 1;

Figure 4 is an enlarged detail section of the lower'r-ear part of thev plow, the section being taken on the vertical median plane of the frame; and l Figure 5 is a disassembled view, partly in section, of the share and its associated parts.

In the embodiment of the invention as here l shown there is provided a 4frame consisting of a pair of'parallel members each havingan archI portion 10 which extends downwardly at the rear to provide a -standard 11 carrying the invention pair may be positioned forwardlyj of the'leg 1s tledvto the arch-.portions 10. r On .,stantially,` 135 to each other.-

device arat its bottom a forwardly extending shoe 12. Each arch portion extends forward to formy a beam' side 13.V The arches and `beam sides are spaced but the standards are brought together attheir lower ends. 'A sole 14lis sec'ured to the shoesV and `projects forwardlyY to Y form a point' 15 of substantially arrowhead shape. '.The metalof theV shoe is Aforgedto provide this pointV lin such mannerlfthata shoulder 16 is formed at the rear of the point]4 Bolts 17 secure the sole to thek shoe so that .the Vsole and or broken. l The upper face of the shoeiis inclined-.upwardly from front. to :rearD and-"extending parallel to this inclined yfaceis a pivot bolt 18 havingaiat head` 19. .Y This bolt passes through the shoulder 16 so that the head 19 4lies'in the hollow ofthe, point. The b'o'ltf18 extends .between the standards and through a plate20 formed on the bottom of a seat supportingleg 21 which'supports at its upper pQ-ntmaybe TSPlacedWhenwOrn: i. l

end a bar or beam 22 by which'the upper end Y the bar22 is mounted a seat or saddle 23'..

vThebolt118.is'provided with a lwasher 24 which'restsagainst the plate 20 .and with a lThe share consists of a substantially square metal plate 26 having all fourv edges" 27 sharpened. This plate isbent along one diagonal line ofthe square` sothat the two triangularv portions ofjthe plate on the 'op-V posite sides of the diagonal line lie at sub-A Within theag.

angle thus formed there isprovided at eachV 4end of the diagnalline Va bearing sleeve 28 through which'the bolt 18 passes. Thefproximal endsl of these sleeves are undercut t0 provide spaced bevelled faces 29. l/Vhenthe' sharey is lthus mounted on the bolt 18 either half may be arranged in vvertical position and the other half will then extend outwardly andk downwardly from the bolt at approxi-A mately 45-0 to the horizontal; Moreover agonal lines either sleeve28`may` be arranged the share being symmetrical about both di,

nextthe point 15. Thus if one pairofedges 7 becomes dull the share mayjbef taken' poif, turned end for 1 end and replaced to `bring# the remaining pairv of edges into use. In connection with the share there is provided a mold board the lower end of which seats on the share and bears against the forward bevel 29. The sides of this mold board extend backwardly from its center line and in the bendthus formed there is provided a sleeve 31 through which passes a bolt 32. A yoke or loop 33 is pivoted to the lower end of the bolt 32 and receives the bolt 18. A brace 34 has its lower end 35'provided with an opening to receive the bolt 18 and ,this

lower end is located just behind therearV sleeve 28. The other 4end 36 of this brace 34 is offset and provided with an opening to receivethe bolt 32, the offset end 35 resting on top .of the sleeve 31. A nut 37 screws onto the bolt 32 to secure these parts together. A bolt 38 extends throughthe brace 34 about centrally thereof and has a hoo-k end `39 which engages the rear bevel 29'.` A washer 40 and butterfly nut 41 are provided for this bolt. By means of the two bolts 32 and 38 andthe brace 34 the mold board is secured rigidly to the share.V Each half of the mold board is provided with a-slot 42 in its upper VVso part. Bearing means 43y are arranged at the sides of these slots and disks 44 are revolubly supported by these bearingmeans and project forwardly through the slots. Pivoted i between the forward lower ends of the arches 10 is a securing lever45 having its lower end Vslotted to en `age the forward edgeof that half of the s are which may be in vertical position. By this means the working half of the share'is held to onel side or the-other of the frame yas may be desired.

Handles A46 are fixedv to the arch.'A A coulter 47 is provided with ashank 48 which extends up between the beam sides and is held in vertically adjusted position Y.by a bolt 49 passing through the beam and selectively through one of a series of spaced holes 50 inthe shank. A wedge 51 vserves to hold the coulter against tilting.

The lorw'ard end of the .beam` extends through an .opening in a vertically adjustable frame 52 supported on ground wheels 53 and the frame 52 is provided with a forwardly extending yoke 54 having an arcuatev front end provided with spaced openings 55. A draw bar 56 is pivoted ,concentrically of the arcuate yoke end and is provided on its forward end with a clevis 57. This draw bar is held in angularly adjusted position Von the yoke by a bolt 58 which passes through the Vbar and selectively through one of the vholes .55. 'Safety chains 59 secure' the ywheeled iframe to the plow proper and pins V60 are usedto adjust ther-rame 52 vertically.

I' Y In use, as the end of each furrow is reached, the plowis turned aroundgand the I l .lever 45 swung to free the share. The shareV is then swung over-to bring the part vprefviously yin the-ground to'vertical position and the lever moved to engage the part just brought into such position. Plowing is now resumed in the opposite direction.

There has thus been provided a highly efficient device of the kind described and for the purpose specied.

It is obvious that many changes may be made in the form and construction of this invention without departing from the material Yprinciples involved. It is not thereforedeysired to confine the invention to the exact rform herein shown and described but it is 'desired to include all such forms and constructions as come within the scope claimed.
