PLOW.

Specification of Letters Patent.

Patented Mai. 31, 1914.

Application filed June 25, 1913. Serial No. 775,750.

To all whom it may concern Be it known that we, Rrmonrn J. ALTGELT and CHARLES F. CAnLsoN, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Flows; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

This invention relates to plows and more particularly to the share and its relation to the other parts of the soil-engaging member or plow bottom,one object of the invention being to so construct a share having no lateral flange or gunnel, that it shall be re inforced or strengthened where the greatest strain occurs, and so that the scouring surface of the share shall be sufliciently raised above the standard to present a scouring surface which will be less concave than is accomplished with a share as heretofore con structed with a lateral flange or gunnel at its rear end.

A further object is to so construct the share and connect it in its proper relation with respect to the mold board, that the latter will be prevented from springing upwardly past the adjacent edge of the share.

With these and other objects in view the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan View of a plow embodying our improvements; Fig. 2 is a side elevation; Fig. 3 is a sectional view, and Fig. 4 is a separate view of the share,

1 represents a standard or frog which may be conveniently made approximately V-shaped in cross section so as to form two wings or members 2, 3 to which the soil engaging members, constituting the plow bottom, are secured, said plow bottom comprising a mold board 4, a share 5 and a landside 6.

The mold board at is secured to the wing 2 of the standard or frog 1, and its forward edge is beveled, as shown at 7. The share 5 is also secured to the wing 2 of the standard and its upper or rear edge is beveled, as at 8, to overlie the beveled forward edge 7 of the mold board and thus prevent the latter from springing upwardly.

The share 5 is constructed without a laterally and rearwardly projecting flange 0r gunnel such as heretofore commonly employed, and it may therefore be termed a gunnelless share. Instead of employing a flange or gunnel, we thicken the forward part of the share, such thickened portion overlying the lower end of the standard and extending approximatelyto the point of the share and has a shape substantially as indicated in the drawing.

The thickened portion of the share may have a shape as indicated at 9 in the drawing, and it may be provided with a shoulder 10. This thickened portion 9 constitutes a patch which may be formed by upsetting, rolling or by welding. The thickened portion or patch 9 serves to reinforce or strengthen the share where the greatest strain and wear are brought to bear, and it also serves to effect a raising of the scouring surface of the share above the standard so as to present a straighter or less concave scouring surface than is accomplished with a share having a flange or gunnel.

A bolt 11 is passed through the reinforced or thickened portion of the share and through the wing 2 of the standard. This bolt serves the same purpose as the gunnel bolt of a gunnel share, but the nut on this bolt is more readily accessible than is the nut on a gunnel bolt, because with a gunnel share, especially on engine and heavy wheeled plows, it is difficult to raise the plow high enough off the ground to get under the same with a wrench.

The land-side 6 is secured to the wing 3 of the standard and projects forwardly under the share so as to assist in supporting the latter, the forward end of said land-side projecting partially across the patch 9 and terminating at the shoulder 10 on the latter.

The share is somewhat thicker than is the mold board, at the abutting edges of these parts, and in order that those portions of the under surfaces of the mold-board and land-side with which the edge of the landside engages shall be continuous (avoiding the presence of an offset) and thus afford a flush surface for the edge of the land-side, the share is depressed or ground off at its upper corner, thus forming in the under face of the share a recess or depression as the landside.

Having fully described our invention what we claim as new and desire to secure by Letters-Patent, is

1. The combination with a plow standard and a mold board secured thereto, of a share provided with a patch at its forward portion and overlying the standard, a bolt passing through the share, patch and standard, and a landside having a tapering forward end underlyingthe major portion of the if patch and terminating near the point of the share.

2. The combination witha plow standard and a mold board secured thereto, of a share provided with a patch at its forward portion and overlying the standard, a bolt pass ing through the share, patch and standard, a separate landside secured to the standard and having its forward portion underlying the portion of the share having the patch, and an abutment near the forward portion of said patch for the forward end of the landside.'

3, In a plow, the combination with a standard, a mold board secured thereto, a share secured to the standard and abutting against the forward edge of the mold-board,

a land-side secured to the standard and en-: gaging the under faces of the mold-board specification in the presence of two'subscribing witnesses.
