JESSE A. PANKEY, 0F MINJJEN, MISSISSIPPI.
To all whom it may concern:
Be it known that I, JEssE A. PANKEY, citizen of the United States, residing at Minden, in the county of Kemper and State of Mississippi, have invented certain new and useful Improvements in Plows, of which the following is a specification.
This invention relates generally to implements for tilling the soil, and refers particularly to a novel construction of plow.
The invention has for an object the provision of a plow which is formed of a few number of parts which are arranged substantially and constructed so as to produce a strong and durable device of this nature which is more applicable to practical use than devices of this nature heretofore manufactured.
The invention has for another object the provision of means in a plow construction for adjusting the pitch of the plow foot or standard in order to dispose the plow car ried thereby at the proper angle incident to the work which is to be performed.
The invention further contemplates the provision of a plow foot which admits of the quick detachment of points and the like thereto and whichwill rigidly secure the same in position when such are employed.
For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which Figure 1 is a'perspective view of a double moldboard plow constructed according to this invention, and Fig. 2 is a side elevation of the lower end of the foot thereof. Fig. 3 is a side elevation of the foot of the frame having a turn plow applied thereto, and Fig. 4 is a bottom plan view of the same.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.
Referring to the drawing in which is disclosed an embodiment of the invention the numeral 10 designates a plow beam which is preferably formed of steel and which is The plow beam 10 is reduced at its rear lower extremity to engage between the companion bars 12 which are disposed in parallel and in spaced relation to form the standard of the plow, the beam 10 being retained between the companion bars 12 by the positioning of a bolt 13 transversely through the Specification of Letters Patent.

standard 12 and the beam 10. This positioning of the bolt 13 admits of the pivotal movement of the beam 10 which is regulated and retained in adjusted position by the employment of a pair of adjusting bars 14 which are connected to the highest point of the arch 11 of the beam 10 and extended b-ackwardly therefrom. The adjusting bars 14 are secured at their rear extremities to the handles 15 of the plow which extend downwardly and are pivotally 1 engaged upon the bolt 13 outwardly of the companion bars 12.
The standard is provided at its upper extremity, the companion bars which form the same being converged, with an elongated slot 16 through which a clamping bolt 17 is engaged which is adjustably positioned through longitudinal slots 18 formed in the adjusting bars 14 in parallel relation. The lower extremity of the standard 12 is extended forwardly in the usual manner to form a foot 19 which carries a frog 20 which is integrally formed therewith, the same being extended outwardly from the forward edges of the companion bars which form the standard 12. The frog 20 is provided with a share 21 having diverged ears 22 which engage with the frog 20 to support the share 21 thereon by suitable bolts or the like, the frog 20 also serving as a support for a double mold-board 23 which flares upwardly and outwardly from the sides of the standard 12. The double moldboard 23 is provided cen-. t-rally with an aperture which registers with the openings between spaced companion bars 12 for the reception of a clamping bolt 24: which is extended rearwardly through the double moldboard 23 and standard 12 and clamped in position by means of a suitable nut 25.
In connection with the device a depth runner is employed which comprises an elongated frame 26 which is longitudinally slotted and through which is vertically disposed a plate 27 having vertically disposed slots formed adjacent the opposite ends thereof and in parallel relation through which are engaged clamping bolts'28 for securing the plate 27 in adjusted position. The forward end of the frame 26 is curved upwardly at an abrupt angle and abutted against the rear edges of the companion bars 12 where it is provided with adepending web 29 which is apertured therethrough in order to secure the frame 26 to the standard 12. In conjunction with this form of plow frame a turn plow is provided and a modified form of the plow support especially adapted to this construction. A standard which comprises spaced companion bars is transversely apertured for the reception of a bolt 31 which engages through a lug 32 stamped and turned inwardly from the share 33 which is disposed at a rearward angle to the standard 30. The share 33 is provided with a landside 34 which extends rearwardly from the forward edge thereof directly against the inner side of the standard 30 and is engaged thereagainstby the end of the bolt 31 which passes through the lug 32. The landside 34 extends upwardly against the standard 30 and is further secured in position by the provision of a second bolt 35 which is engaged through the landside 3 1 and through the companion bars which form the standard 30. A turnshovel 36 is mounted upon the lower portion of the share 33 and is suitably secured thereon by bolts or the like, while a moldboard of common formation is engaged upon the upper end of the share 33 and curved upwardly and outwardly therefrom. The landside 34: is suitably apertured for the reception of bolts or the like to support a bar 38 disposed between the share 33 and the landside 34. In this construction it is readily observed that the standard 12 may be adjusted to various angles by loosening the clamping bolt and swinging the standard into the desired angle, the clamping bolt 17 being carried longitudinally within the slots 18 formed in the adjusting bars 14 and the longitudinal slot 16 formed in the upper extremities of the companion bars which form the standard 12. The depth runner may also be adjusted by manipulating the clamping bolts 28 to permit of the vertical adjustment of the plate 27 in accordance with the desired depth to which the plate 27 is adapted to be engaged.
Having thus described the invention what is claimed as new is 1. A device as specified comprising an arched beam, a standard pivotally engaged with said beam, said standard having an elongated slot in the upper end of the same, handles rearwardly dlverged from said standard at the point of engagement of said beam, a pair of adjusting bars horizontally disposed between said beam and said handles, said bars having longitudinal slots formed in the same, a clamping bolt engaged through said clamping bars and through the elongated slot formed in the upper end of said standard, a frog positioned upon the lower end of said standard, a share carried by said frog and a double moldboard carried by said frog and said standard.
2. A plow including a beam having its rear end curved downwardly, a forked standard secured to said beam, the arms of said standard being engaged against the sides of said beam, a pivot pin secured through said standard and said beam, a pair of handles engaged against said standard and secured to said pin, a pair of companion bars disposed between said beam and said handles, said standard being extended between said bars, and a clamping bolt adjustably secured through said bars and said standard.
In testimony whereof I afiix my signature in presence of two witnesses.
