SPECIFICATION formingpart of Letters Patent No. 657,653, dated September 1 1, 1900.

Application filed February 7, 1900. Serial No. 4,417. iNo model.)

To all whom it may concern;

Be it known that I, EDWARD FOWLER, a citizen of the United States, residing at Cedar Grove, in the county of Walker and State of Georgia, have invented certain new and useful Improvements in Plows, of which the following is a specification.

My invention relates to plows in general, but more particularly to the landside, the object being to reduce the draft of the plow to a minimum; and my invention consists of a drawing-in disk set at au angle to the landside, whereby the landside is drawn orsuoked toward the vertical side of the furrow, said disk extending to a working point beyond the vertical plane of the landside.

It further consists of a peculiarly-shaped shin-board having a rearwardly and outwardly extending upper corner; and it cousists, further, of a reversible plow-point twisted from end to end and of a compound curved shape in cross-section; and with these objects in view my invention consists of the parts and combination of parts, as will be hereinafter set out more fully.

In the drawings, Figure 1 is a perspective view of a plow embodying 'my invention. Fig. 2 is a bottom plan view of the same, portions being removed. Fig. 3 is a side elevation of the same viewed from the moldboard side of the plow, parts being broken away. Fig. 4 is a section on the line44, Fig. 3. Fig. 5 is a perspective view of the reversible point. Fig. 6 is a rear elevation of the point, and Eig. 7 is a detail sectional view of the drawing-in disk and its bearing.

In the drawings, 1 is the plow-beam of approved construction, preferably such as shown.

2 indicates the handles of the plow, attached to the beam by means of the strips or irons 3.

4 is a curved disk suitably journaled to the standard of the plow-beam, and 5 is a scraper for the same of approved construction.

6 is the runner or shoe of the plow, secured to the foot of the standard 7 of the beam 1, said shoe being of the outline shown in Figs. 2 and 3 and provided with a depression or recess 8 in the bottom face thereof, near the forward end.

9 is an arm having the offset end 10, from which projects the lug l1, said arm being secured to the standard 7 by means of a suitable bolt 12, and when secured in lthis position the shoulder 11 fits snugly against the rear edge of the standard 7, thereby locking said arm 9 against movement and making the same very rigid.

13 is an annular lug or boss extending inwardly from the other end of the arm S), in which is secured a journal-brass 14.

15 is a rearward extension or lug integral with the boss or lug 13 and provided with an opening 16, in which the bolt 17 is secured,

vsaid bolt holding the arm or bracket .18,whicl1 is bent in substantially U-shape forni and providedat its end with a scraper 1.) of approved pattern. The inner bearing-face of the boss or lug 13 is finished on an angle sloping toward the land side of the runner.

2() is a drawing-in landside-disk having a peripheral lug or rib 21 and beveled off on its periphery, as clearly shown in Fig. 7, said drawing-in disk being mounted upon the sloping face of the annular boss 13 by means of a bolt 22, which is journaled in the bearing-brass 14 of said annular boss or lug, the outer end of said bolt or journal being suitably screw-threaded, on which the nut 23 is adapted to work and secure said drawing-in disk on said journal or bolt. The arm 9 and `the angle of the face of the boss 13 are of such construction that when secured to the plow-standard 7 the periphery of the drawingin disk is beyond the vertical plane of the landside, as clearly shown in Fig 2.

24 is the landside, provided with the elongated slots 25, through which the bolts 26 pass to secure said landside to the foot of the standard 7, whereby said landside may lbe adjusted backward and forward, according to the requirements and wear of the parts.

27 is the shin-board, having a dependent lug 28, through which the bolt 29 passes to secure said shin-board to the ,ru nner of the plow. Thelandside-face 30 of the shin-board is straight, but incline/s. outward to a point beyond the vertical planeof the landside 24, and 3l is a point extending rearwardly from the shin-board in the Sallie plane with the face 30, there being a shoulder 32, to be herel'OO inafter referred to, between said poin'r and the working face of the shin-board. When the shin-board is properly adjusted, the periphery of lhe concaved disk 4 works over the point 3l and up against the shoulder 32 of the shin-board, and this shin-board being carried by the runner and landside may be adjusted backward or forward, according to' the different-sized disks employed, it being very desirable to change the sizes of disks 4 according tothe character of work and land it is desired to till. The working or top face of the shin-board is of a curvature that will give a winding and turning motion to the soil after the manner of a spiral, so as to thoroughly pulverize or break up lthe furrow as it is turned and forced along said shin-board.

33 is the point of my improved plow, of a compound curve in cross-section, said point having an elongated slot 34, through which the bolt passes to secure said point to the runner or shoe, the nut 36 of said bolt being `secured in the recess or depression 8 in the bottom of the runner, so as to not impede or increase draft. From the various views in this case it will be seen that this point 33 is given a twist, and when secured in the position shown in Fig. 3 itwill have a greater` tendency to work through the soil more thoroughly. Again,it will be seen thatthe draft,or

rather the friction of the earth, will have a tendency to sharpen the extreme point, and when worn ro any extent the point can be reversed,

and it will be found that the wearingjust referred to will effect asharpening of said point. From Fig. 2 it will be seen that the respective edges 37,accordiug to the reversal of the point, project beyond the landside-face to a point beyond the vertical plane of said landside and in the same vertical plane with the Working periphery of the disk 2O and the point 31 of the shin-board. plane of the periphery of the drawing-in disk 20, the point 3l of the shin-board, and the portion 37 of the point, as compared with the vertical plane, of thelandside, itwill be seen that the only points of contact with the land side of the furrow are 37, 31, and 20, thereby redlicing the friction of the landside and draft to2 The angle at which the disk 20 is set is such that in practice, it has beenV a minimum.

found, causes the disk to draw the plow toward the land side of the furrow and prevents it from ridingorjumpingawayfrom the same. In practice it has been found that the drawing powers of the disk 2O are very great and sufficient to overcome all tendencies of the plow to work away from the land side of the furrow, whereby a straight clean-cut furrow may be made. The disk4is secured in such manner to the plow that its periphery works over the point 31 of the shin-board and against the shoulder 32, so that the earth in passing up the shin-board is delivered on the disk 4 From Fig. 2, noting theand prevented from falling between the end of the shin-board and' the periphery of the disk by reason yof the shoulder 32 and the point 3l. If the work requires a smaller or larger disk or the disk wears to any appreciable extent, the shin-board and landside are adjusted accordingly by means of the bolts 26, working in the slots 25 in said landside, whereby the distance between the periphery of the concaved disk 4 and the shoulf der 32 may be regulated at will according to the demands of the case. The point 33, by means of the elongated slot 34, may be adjus'ted with the other parts just referred to.

What I claim, and desire to secure by Letters Patent, is-

l. In a plow,an adjustable landsde carrying ashin-board having a broad concaved working face.

2. ln a plow, an adjustable landside, ashinboard having a broad concaved working face secured to said landside, and an adjustable point in combination with the concaved disk.

y 3. In aplow, the combination with the landside of a shin-board of the character described, extending beyond the vertical plane of the landside.

4. In a plow, the combination with the landside of a rod or arm secured to the vertical standard, of the plow, a bearing on the rear end of said rod having au inclined face, a drawing-in disk journaled in said bearingand on the inclined face, the periphery of said disk extending beyond the vertical plane of the landside.

5. In a plow, lhe combination with the landside of a rod or arm secured to the vertical standard, of the plow, a bearing on the rear end of said rod having an inclined face, a drawing-in disk journaledin said bearing and on the inclined face, the periphery of said disk extending beyond the vertical plane of the landside, and a rearwardly-eXtending lug integral -with said bearing and a scraper bearing against the inner working face of the drawing-in disk.

6. In a plow, the combination with the concaved plow-disk ofa shin-board, and a rearwardly-extending vpoint integral with said board forming a shoulder at their juncture against which the periphery of the concaved disk works. 1

j 7. In aplow, the combination with the landside of a concaved. plow-disk, a shin-board projecting beyond the vertical plane of the landside and a rearwardly-extending point integral with said shin-boardforming a shoulder at its juncture, with said board, against which the said disk works.
