Description

Jan. 7, 1941. H. PETERSON SUBSOILING PLOW POINT Filed May 16, I959 (In uentor Hary .Pefervrb Attorneys Patented Jan. 7, 1941 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to a plow point for subsoiling, the general object of the invention being to provide means whereby the points can be attached to the shank of a plow beam or to a lister beam and also to provide a detachable terminal point so that this terminal point can be removed and a new one substituted for it when worn.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.
In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-
Figure l is a view showing the improved point attached to a plow beam.
Figure 2 is a top plan view of the improved point.
Figure 3 is a section on the line 3-3 of Figure 2.
Figure 4 is a side view of the improved point with the terminal point removed.
Figure 5 is a view of the terminal point.
Figure 6 is a view looking toward the rear end of the terminal point.
In these views the numeral I indicates the improved point which is of angle shape in cross section to provide the flange 2 and the rearwardly extending flange 3, this flange 3 being of considerable width and having a front row of holes 4 therein for receiving bolts 5 for attaching the point to a plow beam B and it is also provided with the holes 6 which together with the upper hole 4 can be used for receiving bolts for fastening the device to the beam of a lister.
The front flange 2 slopes downwardly and forwardly and terminates in a thick part I which extends downwardly and slightly rearwardly and has a slightly tapering recess 8 in its front face.
The terminal point is shown at 9 and has a slightly conical projection ID on its rear end for fitting in the recess 8 and the rear end of the terminal point 9 is formed with a slot H which passes partly into the projection l0 and has its front end enlarged as is shown at l2 so that the slot is of T-shape in side view as shown in Figure 3. A bolt I3 is adapted to be passed into the slot with its head in the enlarged part l2 with the end of the bolt passing through the projection It! and this bolt is adapted to be passed 5 through a hole in the part I and to receive a nut l4 which engages the rear face of the part I to detachably hold the terminal point 9 to the front end of the point I.
Thus as soon as the point 9 becomes worn it 10 can be removed by loosening the nut l4 and withdrawing the old point and substituting a new point for the point 9. Also if the bolt should break a new one can be substituted to hold the terminal point to the point I. 15
In actual use, this subsoiling point has proven to be of immense benefit in preventing erosion of farm ground from wind or water. Its action of breaking loose the plow pan, permits heavy rainfall to be absorbed without excessive runoff, thereby aiding in saving valuable top soil and as it leaves the surface in a cloddy condition any soil drifting by wind is eliminated thereby making it an ideal method of summer fallowing or r for working ground in the fall for spring seed- IB ing.
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be I805 made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claim.
Having described the invention, what is T85 claimed as new is:--
A subsoiling plow point for use with a downwardly and forwardly sloping beam comprising a body of angle shape in cross section to provide a front flange and a side flange, said side flange 0 having a plurality of holes therein for receiving bolts which fasten the point to the beam, the front flange sloping downwardly and forwardly at a steep angle, a front end wall forming part at the ends of the two flanges having its front 5 face sloping downwardly and rearwardly and a. downwardly and forwardly sloping point connected with said face.
