Abstract

A plough having a share with an accompanying tip that is removably secured on the bottom front portion of the share. The tip is so constructed and arranged that it is adjustable on the plough share so that the extent of life of use of the tip can be significantly increased. Thus, the maximum use of a plough share tip may be effectuated.

Claims

1. A plough having a share with an adjustable and removable plough tip for attachment to the bottom front portion of said share, comprising at least three fixed points on both said share and said plough tip, at least two points on said share being arranged to align with two points on said plough tip, means co-acting with said points for removably locking said plough tip to said share in a predetermined position, said points being apertures in said share and said plough tip respectively, said apertures in the share and plough tip, when aligned, having said means to lock said share to said plough tip in a selected position, said apertures in said plough tip being in alignment and located equidistant from adjacent apertures, said points on the plough tip having the capability of permitting the peripheral edges of said plough tip to assume a multiplicity of positions on said share, said apertures in said share being arranged whereby the first aperture is located in the outer lower front part of said share, a second aperture being located upwardly and rearwardly from said first aperture and at an angle of approximately 45°

to the horizontal plane, and a third aperture being located obliquely below said second aperture, and the distance between said first and second apertures being equal to the distance between the first and third apertures, whereby the entire periphery of said plough tip can be used as a cutting edge.

2. The combination as claimed in claim 1 wherein said share is further provided with a fourth aperture, said fourth aperture being aligned with said first and second apertures at a distance from the second aperture which equals the distance between said first and second apertures.

3. The combination as claimed in claim 1 wherein the width of said share increases in the direction toward said front edge.

4. The combination as claimed in claim 1 wherein said plough tip is prismatic having two uniform sides, each of said sides having a flat surface and four contiguous surfaces inclined thereto, and the ends of said contiguous surfaces which are remote from said flat surface merging into cutting edges, and said flat surfaces of said plough tip having said apertures therein.

5. The combination as claimed in claim 4 wherein there are four separate cutting edges on said plough tip.
