PLOW.

SPECIFICATION forming part of Letters Patent No. 335,348, dated February 2, 1886.

Application filed Septemherflfi, 1885. Serial No.178,250. (No model.)

To all whom it may concern:

Be it known that I, LEwIs Grass, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have i11- vented a new and useful Improvement in Flows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to improvements in plows; and it consists in providing an improved standard; also relates to and consists in providing improved methods of attaching a mold-board and landside to a main standard.

M y invention also relates to and consists in certain improvements in a metal plow-beam and the manner of adapting the beam and the standard to each other.

My invention further relates to and consists in means provided for the adjustment and support of a jointer-beam; also for adjustment and support to a shank for revolving cutter; also relates to and consists in certain improvements in plow-clevis and certain other improvements of construction and combination of parts, as hereinafter specified, and set forth in the claims.

Figure 1 is a side elevation of my improved plow, showing the manner of connecting the beam to the standard; also the means empioyed and the manner of supporting the j ointer-beam. Fig. 2 is a perspective of my improved standard and a section of the plowbeam. Fig. 3 is a view of the front end of plow-beam with revolving cutter attached. Fig. 4 is a sectional view of the clevis. Figs. 5 and 6 are views in detail of the j ointer and cutter support. Fig. 7 is a view of section of mold-board.

A is the plow-beam; B, the standard; 0, the mold-board; D, the landside; E, the share; F, the jointer; G, the jointer-beam; H, the revolving cutter; J, the clevis.

K is an adjustable support for the jointerbeam and revolving cutter.

The beam A has semicircular longitudinal concaves t on each side, forming a beam composed of an upper and a lower flange, a,united by the web a. The front end is drawn down and adapted for attachment with a clevis. The rear end is drawn down, as shown in Fig. 2, and a foot-piece, R, formed thereon, and adapted for bolting to the wing M of the standard B, which is provided with perforations c and c, that coincide with perforations e and e in the foot R of the beam. Through these perforations bolts may pass to secure the beam to the standard.

The standard B is provided with a wing, L, which projects outward and backward as a support for the mold-board, also the wing L, which projects downward, outward, and forward as a support for the shear. The wing L is provided with the perforated bosses b b, which are adapted tothe countersinks b I). The standard is also provided with a wing, M, projecting rearward for the support of the landside, and the foot R of the beam, as heretofore stated, and is provided with perforations 0 and 0, also f and f.

At the upper end of the standard B there is provided a head-flange,T, set over to the moldboard side the thickness of the beam from a perpendicular line, T, of the standard. The head T projects to the rear of the standard, and is provided with lugs 57 g and a perforation, I, for a bolt, by which the beam is bolted to the standard; or the lugs may be formed into a rib extending from the lower to the upper side of the head. In either case the lugs or rib should be adapted to the shape of the beam. I prefer the lugs, for the reason that there is a less amount of metal required, and the standard is more easily molded. \Vith the head so located, when the beam is passed down between the landside M and the head T, the foot R bolted to the landside on the moldboard side, the head T to the beam on the mold-board side, the beam will be in the rear of the standard, leaving the land side of the standard free of projecting obstructions. The head T is connected to the wing L by a flange projecting outward and forward, forming a junction with the top of the wing L.

The wing L is provided with perforations it, through which bolts may pass to secure the share to the standard.

In the manufacture and use of plows, it is desirable to have a supporting-standard that is adapted to the use of a chilled cast-iron moldboard, as well as a hardened-steel 1nold board, and that they may be interchangeable, so as to adapt the plow to the peculiarities of soil in different localities; and to secure this ,pose of adjusting the parts mentioned.

object the standard should be so provided and adapted as to meet the requirementsof a thick cast-iron mo1d-board,as the cast mold-board, to have the requisite strength and temper, should be at least one-half thicker than a steel mold-board. To accomplish this desirable result, there is an offset, 0, formed at the juncture of the wings L and L, forming a depression, 0, in the face of the wing L. This depression Ois provided to form alocking-shoulder and to adapt the standard for the use of a thick cast mold-board, and the perforated bosses b I) are provided as a support for and on which the steel mold-board may rest and be secured by bolts passed through it and the wing L of standard B. proper adjustment of the mold-board and the share, as shown at k, Fig. 1, and when desirable to use a mold-board of cast metal it should be provided with the countersinks b b, which are adapted to the height of the bosses b b, and

when placed on the standard,the bosses passed into the countersinks, the top surface of the cast mold-board will be brought to the same line of adjustment with the share as that established by and for the use of the steel moldboard, and the same bolts secure the mold boards to the wing of the standard. The landside is bolted to the standard by bolts passed through perforations f and f and 0. Under the shoulder at this projection extends to the top of the standard, the front edge, (1, supporting the moldboard, the follow-board resting under the shoulder (Z, and forming with it a continuous support for the edge of the mold board,which forms with the share a continuous cutting-edge from the point of the share to the top of the mold-board. The beam may be bent, as shown in Fig. 1, giving it the proper height over the front of the plow, and dropping the front end down to a desired line of draft. The handle N is bolted to the landside, as shown, and supported by the brace Q, connected to the beam.

The adjustable support K (see Fig. 5) for the jointer-beam G is secured to the beam A by means of the clip m and the bolts n by passing the bolts it through the ears pp on the piece K and the clip m on the opposite side of the beam. A bolt, j, projecting through the center perforation of the disk, passes through the disk K and the jointer-beam. The outer edges of the disks are serrated and adapted to each other as a means of adjustment. The disk K may be vibrated about the center bolt, j, and fixed at any desired point by drawing the serrated edges together, thus adjusting the beam G and j ointer F to a greater or less depth; or the jointcr may be thrown up above the surface of the ground when desired. The disk K is provided with the ribs 1' 1', as a support to the beam G.

I wish to call especial attention to the adjustment of the disk K on the beam, and the diskK rotating about ya bolt or pin central thereto and engaging therewith, for the pur- (See This would secure a Fig. 6.) The disk Kis also provided with an annular socket, S, as a support for the shank 't. (See Fig. 3.) This shank is formed in three sectionsthe main section, it, and a parallel section, a, united by. a right-angle section, 2), in the form of a crank. The yoke '10 has a pivotal connection about section a of the shank, and by rotating the shank t in the sockets the desired lead maybe given to the revolving cutter, and the shank then securely held in position by the use of the set-screw or the shank may be raised and lowered by moving the shank t up or down, thus setting the cutter H in the desired relation with the plow share or point. This clamping device is brought intofurther use, as indicated by the dotted lines, (see Fig. 1,) as a support for an adjustable removable colter, L By moving the clamp on the beam and adjusting the disks, as shown in Figs. 1 and 3, a great variety of changes and uses may be made of these means.

The guidewheel WV (see Fig. 8) is supported by the shank 10 at the lower end of which there is a spindle, w. The'shank is held to the beam by the clamping-plate WV, (see Fig.

9,) which embraces the beam A, and is provided with the jaws 10 20 w, and 10 These jaws embrace the wheel supporting shank 10 and is operated in the following manner: Place the clampingplate W on the beam and pass the shank w up between the beam and the jaws, and when adjusted fix the parts in position by turning in the set-screw w. This adjusting mechanism is simple and easily adjusted, and will hold the parts securely in the desired adjustment to secure the required strength in shank w and the clamping-plate W. I prefer to make them of malleable iron.

The clevis is composed of the plates J,which are placed one on each side of the beam, and secured by through-bolts, the draft-bar 1, and link z. The plates J are provided on their front edges with the notches q. The draft-bar y is provided with a rib or ledge, y, adapted to rest in any one of the notches, and the rear end thereof is secured in position by a boltor lugs, 00, which latter pass through a perforation, q, corresponding to the notch q,occupied by the rib y. The link 2 is secured to the draft-bar g by a bolt or pin, 3
