BEET-PLQW.

SPECIFICATION forming part of Letters Patent N0. 767,919, dated. August 16, 1904. Application filed May 21,1900. Serial No. 17,480. (No model.)

T all whom, it may concern,.-

Beit known that I, HIRAM FRANCIS THOMP- at Springville, in the county of Ventura and State of California, have invented a new and useful Beet-Plow, of which the following is al specification.

This invention relates to a plow for loosening the ground around deep-growing roots,

such as beets in rows.

The object of my invention is to .provide a beet-plow of superior construction, of'rnaximum strength with minimum weight and cost,

and all the wearing parts of which may be readily replaced.

A further object of my invention is to provide a superior arrangement for a reversible chisel.

Another object is to provide a beet-plow having a standard free from soil-moving attachments except at the extreme lower end thereof.

It is also an object of my invention to so construct the plow as to avoid friction as much as possible.

Another object is to so construct and arrange the chisel or cutter as to protect the bolts and connections which are underneath in such direction as to cause the plow to run evenly In carrying out this invention a broad andl thin standard of considerable length is employed, and in practice the cutter runs at considerable depth below the surface, and

consequently it becomes necessary to provide against any swerving or turning of the standard or cutter from the desired line of draft. rIhis is accomplished by combining with the standard a plow-beam and draft-bar pivote'd to the standard below the beam at the front edgel of the standard and means for adjusting the front end of the draft-bar vertically and laterally independently.

rIhe accompanying drawings illustrate my' invention.

' tially the same width as the Iiange.

Figure I is a view of the invention from the side which will be toward the beets in the process of loosening' the soil for harvesting beets. Fig. II is an elevation -of the other side of the plow. Fig. III is a plan section on line III III, Figs. I and II. Fig. IV is a section' on line IV V, Figs. I and II, with the chisel in place. Fig. V is a sectional plan on said line with the chisel detached. Fig. VI is a side elevation, on a larger scale, of the point c and the chisel which is bolted thereon. Fig. VII is a front elevation of the front end of theplow-beam and the stirrup which adjustably holds the i ront end of the draft-rod.

A indicates a thin straight vertical-edged standard having at its lower end a lateral approximately horizontal blade or shear B and aforwardly-extendingchisel-supportingpoint c. The point c is a forward extension of the landside C. The lateral blade B is bolted to the lower end of the standard A, and the landside C is also bolted to the standard A, and its front edge extends approximately at a right angle from the side of the standard and from the line of draft, said edge being slightly rearwardly inclined, as shown in Figs. IV and V, so as to cut the earth and roots with a slight drawing movement or rake. The point c of the landside C is provided with an upwardly and rearwardly sloping shield to shield the joint'between the standard and the lateral blade.- A.The shield is preferably composed of a detachable and reversible chisel-bladel D, which is bolted by bolts 1 2 to a laterally-deflected upper edge forming a flange 3, which projects to the right from the landside in front of the standard A and extends suficiently far beyond said standard to forma protection for the joints and bolts which are below the ground when the machine is in operation. The fiange 3 adds strength to the forward end of the landside by forming an angle therewith,

and being of but little greater width throughout its length than the thickness of the standard it affords a suflcient seat for the long narrow parallel-sided blade D, which is substanrIhe object of constructing the flange and the blade in this manner is to cause the least possible amount of earth to be displaced as the plow IOO moves forward, and this amount is located upon both sides of the standard, owing to the fact that the standard is located substantially on a line with the longitudinal center of the blade. As the blade is flat and extends horizontally laterally from the side of the standard with its point of attachment in a line with and to the rear of the blade D, the plow can be moved through the ground with but little friction and at such a distance from the beets as to cut off' their roots without coming in contact with their top portions.

E indicates a detachable edge piece or knife for the straight-edged standard A. The front edge of the standard A is preferably in a plane at right angles to the side of the standard,v

and the rear edge of the cutting edge piece or knife E is in a like plane to fit against the front edge of the standard. The front edge e of the edge piece E is sharpened so as to cut through the earth with the greatest facility. Said edge piece is bolted to the plow-beam F by a bolt 4: and to the landside C by a bolt 5, which also passes through an upturned flange of the lateral blade or shear B, the nut of the bolt being on the shear side under the protection afforded by the chisel D and the chiselholding flange 3. 6 indicates a corresponding bolt through the front portion of the standard A and through the landside, thus holding the landside, standard, and shear firmly together. 7 indicates an additional bolt through the landside and rear portion of the standard to hold the standard and landside firmly together. The heads of the bolts 5 6 7 are countersunk in the landside and are flush with the landside in the ordinary manner of countersunk bolts in the landsides of plows.

rlhe standard A is thin and flat and in ordinary practice the dimensions of the same made of steel will be about six inches wide by onehalf inch thick for a length of twenty-six inches from top of beam to bottom of landside. The knife or detachable edge Eis about two inches broad, and its rear edge is of substantially the same thickness as the front edge of the standard.

8 and 9 indicate bolts passing through the beam F and standard A to firmly bolt the beam and standard together. The thin standard A is applied to one side of the beam and an angle-plate Gr is applied to the under side of the beam and one flange thereof extends along the beam and is bolted thereto and the other flange extends across the face of the standard and is fitted against the side of the standard A and its edge piece or knife E.

H indicates a clevis, which embraces the standard, edge piece, and the lower wing or flange g of the angle-iron G.

i 10 indicates a bolt through the clevis, standard, and lower flange g of the angle-iron brace Gr.

11 indicates a bolt through the clevis, lower or vertical flange g of the angle-iron, and the cutting edge or knife E. 12 indicates an additional bolt through the angle-iron flange and the rear edge of the standard.

13 and 14 indicate two vertical bolts through the plow-beam and top flange g of the angleiron Gr.

A draft connection I is pivotally connected with the standard by means of the clevis H .and extends forward underneath the plowbeam F to the front end of the beam and is rigidly connected with the front end of the beam. The connection between the front end of thel draft connection I and the front end of the beam F is preferably adjustable vertically, so that the point atwhich the power is applied to draw the plow forward can be adjusted vertically. For this purpose a stirrup J ,provided with slots 7' in its side arms or limbs y", is clamped to the front end of the plow-beam by a bolt K, passing through the slots and fastened to the beam. By loosening the bolt and adjusting the clevis vertically the front end of the .draft connection 1 will be raised or lowered, as may be desired.

Means L for adjustably fastening the front end of the draft connection I to the bar j" of the stirrup are provided to allow the front end of the draft connection to be moved laterally, so as to shift laterally of the front end of the plow-beam the point at which the power is applied to draw the plow forward.

By means of the vertically-adjustable stirrup a very great length of vertical adjustment of the front end of the draft connection is provided for without any heavy, complicated, or expensive means. When it is desired to cause the point c to run deep into the earth, the stirrup will be drawn up to bring the front end of the draft connection I close to the under side of the plow-beam. When the conditions .of the soil are such that the plow is liable to run too deep, the stirrup is adjusted downward to bring the front end of the draft connection lower, thus giving the point a tendency to run to a less depth in the soil. The stirrup with slotted limbs j affords a very great length of vertical adjustment for increasing or diminishing' the depth to which the plow will be inserted into the ground.

M indicates a standard which may be used for a colter (not shown) or for a supportingwheel N, which supports the front end of the plow-beam.

The draft connection I may be of any suitable form; but I prefer to make it of a rod linked at its rear end by an eye/ to the clevis H.

The means for adjustably connecting the front end of the draft-rod with the cross-bar j" of the stirrup ispreferably an eyebolt L, thi ough the eye of which the rod I passes. The cross-bar j" is provided with a number of bolt-holes 15, so that the eyebolt L may be placed at any point desired. The rod l is supplied at its front end with a link O, to which IOO IIO

IIS

the power may be connected for drawing the plow forward.

The chisel-supj'iorting flange 3 is provided with a row of bolt-holes 16, and the chisel is provided with two sets (Z d of countersunk boltholes staggered with relation to each other-that is to say, the chisel D is provided along one side of the chisel and at one side of the mid-length thereof with two bolt-holes Z and is provided along the other side of the chisel and at the other side of the mid-length with two other bolt-holes df, all of said boltholes being' countersunk upon that face of the chisel which is beveled at the ends. By' this arrangement the chisel can be shifted up and down the face of the flange 3 and can be fastened at any desired point by means of the bolts l 2, the heads of which fit the countersinks in the top face of the chisel D. rIhe sets of bolt-holes are located close to the middle of the chisel, so that considerable wearing material at the ends of the chisel is provided. Vhen the front end of the chisel becomes worn so as not to be eective, the bolts l 2 will be removed by the workman and the chisel reversed end for end, leaving the beveled face uppermost, and the chisel will be again fastened by the nuts screwed home to hold the chisel. When' both ends have been worn,

they may again be sharpened, and this may be continued until the chisel is so short that its further use is undesirable.

In practical operation in the process of digging beets the plow-will be inserted into the ground in the usual way and will be driven along so that the standard will run very close to the left side of the row of beets, so that the shear or bladeB will pass along underneath the beets, thus to thoroughly loosen the ground at one side and underneath the beets, thus allowing the beets to be readily removed from the earth. The draft-bar I transmits the draft directly to the broad standard at the front edge thereof, thus guiding it and the cutter as desired and without destructive strain on the connection between the standard and the beam. As the plow moves forward the earth is broken up and lifted by the chisel D above the level of the bolts 5 6 and the joint between the standard and the blade, and thereby shields the same from any contact with the unbroken soil and from much wear to which said bolts and joint would otherwise be subject.

By arranging the blade B in an approximately horizontal plane, with the front edge thereof at a right angle to the side of the standard, said blade is adapted to cut through the soil with the least resistance and requires no brace outside its own body.

What I claim, and desire to secure by Letters Patent of the United States, is-

l. In a plow, in combination, a standard, a landside formed of a bar fastened to the standard and extending forward thereof and provided in front of the standard with a laterallydeflected upper edge forming a flange having' a forwardly and downwardly slanting face, a chisel-blade fitted upon the slanting face, and bolts through said blade and flange to hold the blade on said slanting face.

V2. In a plow, in combination, a standard, a landside formed of a bar fastened to the standard and extending forward thereof and provided with a laterally-deflected upper edge forming a flange in front of the standard, said flange being provided with bolt-holes, a chisel-blade fitted upon the upper face of the flange and provided vwith bolt-holes and bolts inserted through the blade and the flange and fastened by nuts on the -under side of the flange.

3. A beet-plow provided with a straight vertical-edge standard, a lateral blade fastened to the lower end of the standard, a landside on the lower portion of said standard, the forward portion of said landside being aslant, and a blade lying on the upper forward edge of said landside and extending over the same and in front of the joint between the standard and landside, the rear edge of said blade extending above and forwardly of the joint between the standard and the lateral blade.

4. In a plow, two vertical flat members, one in front of the other and each having its ends perforated and one of them having its front edge sharpened, a perforated beam secured flatwise to the sides of the upper ends of said members, a perforated flat landside secured to the sides of the lower ends, the forward end of which is provided with a flange, a flat blade upon said flange, and a laterally-extending blade secured at a point to the rear of said flange.

5. In a plow, a beam, two flat members secured vertically to one side thereof, one in front of the other, an angle-iron secured to the under side of the beam and to the side of said members, a clevis secured to the members and to the angle-iron with its ends overlapping the joint between the members, and a draft-rod secured at its rear end to the clevis.

6. In a plow, a beam, a thin flat standard secured thereto, a thin flat landside secured to the lower end of the standard, the forward end of which is provided with a long, narrow, inclined flange, a long, narrow blade secured to the flange with its longitudinal center substantially in line with the standard, and a laterally, horizontally-extending flat blade secured at a point in line with and to the rear of said flange.
