This invention has for its object the provision of a strong and durabl'e'breal'nng plow in which the point and share Wlll be cti'ectully reenfor-ced and the depth to which the point may enter the ground may be easily regulated;

The invention also has'for its object the provision of means whereby the beam will be connected with the mold board so as to brace the same and the handles will be mountedin' such a manner thatthe beam may be readily adjusted to regulate the depthof the cut.

The invention isillustrated in the accomhpanying drawings and will be hereinafter fully set forth.

In the drawings: Figure 1 is av side elevation of viewed from the mold board side.

Figure 2 is'an enlarged rear elevation, the

a plow beam. and handles being broken away.

Figure 3 is an elevation viewing the land--' side side of the plow.

Figure 4 is a. horizontal section on the line of Figure 3.

vertically through the slot in thefront'end of the foot and the adjacent parts about on the line 55 of Figure 4.

Figure 6 is an enlarged detail view of the lower end of the standard with the foot,

showing the moldboard side of the same.

Figure 7 is a perspective View of the from In carrying out the vided a beam 1 of approved form provided 5 at its front end with a clevis or other draft device 2 and having its rear end curved clownwardly to form a standard 3. The lower end of the standard is formed integral with a 7 foot 4 having an openlng 5 through its rear 49 end whereby it may be pivotally attached to the landsid'e and having a slot 6 formed through its front end on an arc concentric with said opening 5. a A lateral projection 7 is formed on the foot 4L at the sidesof the" slot 6 and the innerrface of this projection is formed with horizontally extending corrugations or teeth as shown at 8, the purpose of which will presently'appear. The landside 9 is a straight rectangular bar of theusual form disposed in the horizontal plane of the Figure 5 is anenlarged detail section taken invention there is pro-' foot 4 of the standard at the outer side there of and connected therewith by transverse bolts, as will be understood. Between the foot l and the landside is interposed a frog 10 which has a longitudinal portion'substantial- 1y of the same form and dimensions as the lane-side andsecured to the landside and the standard by the same bolts which connect the landside to the foot l of thestandard. At its front end the frog is formed with a lateral wing: 11 which is-shaped to conform to the rear of the mold board 12 and the share 13 and bridges the joint between the share and the mold board, as shownclearly in Figure 2. The share 13 1s iorined integral wlth "thefpoint 14 and the point is formed with an abrupt rear end abutting'the front end of the landsidc, as shown at 15, the

line of merger between the share and the point being curved, as shown at 16, and the frog having a similar curve uniting the wing 11 to the main bar of the frog so'that the parts will be very efliciently recniorced, as willbc understood upon reference to Figure 4. To further reenforce and brace the mold board and the share an arcuate strap brace 1'? is provided, the forward end of this brace being secured to the mold board and the share adjacent the edge of the wing 11 and the rear end of the brace being secured by the bolt passing throughthe landside, the frog and the opening 5 in the foot l, as will be understood'upon reference to-Figure 4. The mold board is further braced by an angle strap bracket 18 which has one arm secured'to the rearside of the mold board and its other arm extendedrearwardly'adjacent the standard 3 and longitudinally slotted, as indi'cated at 19 in Figure 3. The inner side of the rearwardlyeXtending arm is further providedwith notches indicated at 20 in Figure 2, and a washer 21 having mating notches is placed "againstthe same whercby when the securon the bolt and turned home against the washer.

To the rear side of the mold board, approximately at the center of the same, is secured a strap which has its upper portion twisted somewhat so that one handle 26 may Cir be secured thereto. The other handle 27 is secured to a strap 28 which has its lower end secured to the side of the standard 3 and projects somewhat therefrom at its upper end. This manner of mounting the handles will permit them to be easily removed when necessary without dismantling theworking parts of the plow, and the handles are reenforced and prevented from dropping by bracing links 29 which are secured at their front ends to the standard at the point where it merges into the beam and have their rear ends adjustably secured to the respective handles.

. It will be readily seen from the foregoing description, taken in connection with the accompanying drawings, a very strong and durable plow which is not unduly complicated in its construction. By loosening the nut 23 and the nut on the bolt through the hole 5 in the rear end of the foot, apivotal movement may be imparted to the foot t about said bolt so that the front end of the beam 1 may be adjusted vertically relative to the plow point 14; and, of course, after the beam has been set at the desired angle,

the nuts are again turned home. The corrugated construction of the opposed faces of the projection 7 and the washer 22 will relieve the strain on the threads of the bolt 24: and maintain the beam in'the position in which it has been set and thedepth of penetration by the point let may be thus easily regulated without requiring the driver to exert undue pressure upon the handles. The bracket 18 is obviously readily adjustable to accommodate the varying angular relation between the standard 3 and the mold board as the standard is adjusted in the just described manner, and this bracket is located nearer the landside edge of the mold board so that it will aid in resisting the thrust upon the plow. The arcuate brace 17 and the frog 10 very effectually reenforce the point and the share and consequently prolong the life of the plow. The described adjustment permits the user of the plow to set the point 14 to make the proper out under any circumstances and thereby avoid excessive wear upon that I have provided the point and the share so that the necessity for frequently re-sharpening the point and the share will be avoided.

Having thus described the invention, what is claimed is:

1. In a plow, the combination of a mold board, astandard at the rear of the mold board, a bracket secured to the rear side of the mold board and having a slotted member disposed against the inner side of the standard, said slotted member having a corrugated inner face, a washer fitted against said corrugated and slotted member and mating therewith, and a securing bolt inserted through the standard, washer and said slotted member to adjustably secure the parts together.

2. In a plow the combination of a plow body comprising a mold board, a share and a landside, of a standard provided at its lower end with a foot disposed at the inner side of the landside and extending rearwardly longitudinally thereof, means for pivotally connecting the rear end of the foot with the landside, and means at the front end of the foot for locking the foot in its position of angular adjustment. Y

3. In a plow comprising a mold board, a share and a landside, a standard provided at its lower end with a foot disposed at the inner side of the landside and extending longitudinally of the same, a lateral projection on the inner side of said foot at the front end thereof, said projection having horizontal corrugations on its inner face and'there being an arcuate slot formed through the projection and the front end of the foot, means for pivotally securing the rear end of the foot to the landside, securing means inserted through the landside and through the arcuate slot in the foot and said projection, and handles connected to the standard.

In testimony whereof I affix my signature.
