SUBSOIL PLOW.

AQUINTON JROME HOKE, THOMAS VESTER CAMPBELL, AND WILLIAM M. BIGGER, OF NEWPORT, SOUTH CAROLINA.
SUBSOlL-PLOW.
SPECIFICATION forming part of Letters Patent No. 612,901, dated October 25, 1898.
Application tiled March 3 1 l 8 9 8.
To all whom it may cow/cern:
Be it known that we,QUINroN JEOME HOKE, THoMAs WEBSTER CAMPBELL, and WILLIAM M. BIGGER, citizens of the United States, residing at Newport, in the county of York and State of South Carolina, have invented a new and useful Subsoil-Plow, of which the following is a specification.
This invention relates to subsoil-plows, and has for its object to reduce the friction to the smallest amount possible, so as to lighten the draft and facilitate the penetration of the subsoiler when advancing to its work.
For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.
The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure l is a perspective view of a subsoilplow, showing the application of the invention. Fig. 2 is a side elevation of the stand ard and subsoiler. Fig. 3 is a plan section on the line X X of Fig. 2. Fig. 4 is a plan View of a different form of point.
Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by the same reference characters.
The standard l is secured at its upper end to a plow-beam 2 of ordinary construction, said standard being thin and wide and arranged with its width parallel with the line of motion of the plow, so as to offer the least resistance to the passage of the standard through the soil when the plow is drawn forward. The front edge of the standard is sharpened to a knife-edge, so as to cut roots, sod, and like obstructing matter, thereby facilitating the advancement of the plow.
The subsoiler consists of a plate having its lower edge portion bent laterally, forming a runner or furrow-bar 3, the vertical portion of the plate being approximately of triangun lar form and having its front edge sharpened and sloping rearwardly and upwardly, form- Serial No. 675,990. (No model.)
ing a colter 4. This subsoiler is rigidly attached to a side of the standard lin any convenient and substantial manner. The front portion of the runner or furrow-bar dips or curves downward slightly and is adapted to have a point 5 secured thereto, said point comprising rearwardly-divergent members G and 7, between which is received the front end of the part 8. The point is formed of a strip of steel of suitable width and thickness doubled upon itself and having the folded end welded and sharpened, so as to readily` penetrate the soil. The rear portion of the point at the side opposite the colter is cut away, as shown at 8, for the reception of the colter, thereby permitting the front edge portion of the point projecting slightly beyond the side of the colter or coming about ush therewith. The shoulder 9, formed by cutting away the part 8, is adapted to abut against the lower front end of the colter, thereby forming a stop which relieves the fastening between the point and part 3 of the major portion of the strain coming upon the point.
As clearly indicated, the lower member '7 of the point- 5 terminates a distance below the plane ofthe runner or furrow-bar 3. Hence the plow when in operation produces a trench or furrow for the desired purpose. In some instances it is desirable to have the point provided with a wing 10, as shown in Fig. 4, said wing extending outwardly and rearwardly andbeing particularly adapted for cutting under and lifting cotton-stalks.
Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-
l. In a subsoil-plow, a subsoiler formed of a plate having its lower edge portion bent laterally, providing a runner or furrow-bar and having its vertical portion of approximately triangular form, the front edge of the vertical portion of the plate sloping upwardly and rearwardly and being sharpened to a knifeedge, substantially as set forth.
2. In a subsoil-plow, the combination with a colter having a laterally-extending runner orfurrow-bar, of a point secured to the front end of the said runner and comprising upper and lower rearwardly-divergent members bea point secured to the front end of the runner and having the rear edge portion adjacent to the oolter out away, substantially as and for the purpose set forth.
In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
