PLOW.

SPECIFICATION forming part of Letters Patent No. 437,217, dated September 30, 1890.

Application filed May 17, 1890. Serial No. 352,253. (No model.) I

To all whom it may concern.-

Be it known that I, J AMEsARoHERMARTm, a citizen of the United States, residing at UniontoWn, in the county of Perry and State of Ala- 5 bama, have invented certain new and useful Improvements in Flows; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making apart of this specification, and to the letters of reference marked thereon.

This invention relates to certain new and useful improvements in plows; and it has for its objects among others to provide an improved plow, to make the draft lighter, to prevent obstructions underneath the plow, and to otherwise improve upon the prior forms of this class of devices.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure lis a side elevation of my improved plow with parts broken away. Fig. 2 is a rear end view of the same with the handles broken ofi. Fig. 3 is a bottom plan of the integral point and landside detached. Fig. 4; is avertical cross-section through the mold-board.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the plow-point, which is formed integral with the bar A and with a loop 00 upon the inner face of said bar, also with a lug b, to which the lower end of the left-hand handle B is secured by a suitable bolt c, as shown in Figs. 1 and 2. To the inner face of this handle is secured the beam 0, which is also secured to the standard D, the lower end of which is fitted in the loop a of the bar, as shown best in Fig. 1. This brings the beam in the same vertical plane as or in line with the bar.

E is a vertical rod hooked at its lower end and engaging the loop'a of the bar, as shown in Fig. 1, and passed through the mold-board and through the beam, and upon its upper end receives a nut d, as shown, thus serving tachably secured thereto the upper portion of v the mold-board or colter G, which is formed upon the compound curve. (Shown best in Fig. 4.)

The right-hand handleH is lined upon both sides near-its lower end by steel bars f, the right-hand-side one of which extends along under and follows the contour of the said upper portion of the mold-board or the colter, and is secured thereto upon its under face, as shown best in Fig. 2. The left-hand one of these bars or braces is extended diagonally across to the other handle in a sort of Z shape, and has its end secured to the lefthand handle by the same bolt that secures the said handle to the bar A, as seen in Fig. 2. This leaves no obstruction underneath the plow. This colter may be readily applied or detached when desired by loosening the nuts on the bolts which secure it to its supports.

I is a weed-cutter, preferably of steel, secured upon the landside of the plow to the beam and bar A and extending upward upon a curve with its forward edge sharpened'and above the point of the plow, as seen best in Fig. 1.

In operation, as the plow enters the ground, instead of tearing and breaking the sod and roots, the cutter will cutthem with much less power and render the plow easier to operate. This cutter, extending as it does above the plow-point, serves to prevent the throwing of the dirt or sod to the left of the plow, and the sod is cut, not broken.

The form of the upper part of the moldboard is important. By it the sod passes up the inclined plane and strikes the right-angle bulge leading from the lower corner of the hoe to the right-angle curve of the mold-board, and as it reaches this point the lower corner of the board being concave lightens the draft and breaks the sod, and the rise and twist of the board puts it on the bed in a pulverized condition.

The several features above outlined combined unite to make a plow that from practical tests has proved a most efticient agricultural implement and one that will run with less power than those of other constructions. What I claim as new is 1. In a plow, the combination, with th plow-point, the standard D, and the moldboard, of the beam, the handles, the steel bars f, secured to the lower end of one of the handles, and one of said bars secured to the inner face of the mold-board and the other to the other handle, and the brace F, arranged angularly and connecting the mold-board and standard, substantially as specified.

2. In a plow, the combination, with the
