PLOW.

SPEQIFICAI'ION forming part of Letters Patent No. 336,734, dated February 23, 1886'.

Application filed December 19, 1885. Serial No. 186,909. (No model.)

To aZZ whom it may concern.-

Be it known that we, GEORGE M. NEEDLEs and ERNEST G. FISHER, citizens of the United States, residing, respectively, at Stuart, in the county of Holt and State of Nebraska, and Atlantic, in the county of Cass and State of Iowa, have invented certain new and useful Improvements in Flows; and we do declare the following to be a full, clear, and exact de- IO scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,

which form a part of this specification.

Our invention relates to plows; and it consists in novelfeatures whereby the draft is lightened and a furrow cut which will be wider than a given width of plow.

To these ends and to such others as my invention relates, it consists in the details ot'construction shown and hereinafter more particularly set forth and claimed.

In the drawings, Figure l is a perspective view of a plow constructed according to my invention. Fig. 2 is a view in elevation as seen from the land side,'parts being broken away. Fig. 3 is a view in elevation looking toward the mold-board, partly in section and 0 portions being removed and broken away. Fig. 4 is an enlarged sectional detail throughthe axis of one of the mold-board rollers. Fig. 5 is an enlarged detail sectional view in line 00 00, Fig. 3, of the rotary land-side cutter 5 and its bearing, showing the removable side.

The beam A, which is preferably made of metal, is flattened at its forward end and perforated to form a clevis, a. Its rear portion is bent downward, forming a standard, B, which 0 terminates in a crosspiece or landside, b, and share-bar b, to which the share 0 is secured. A colter, D, is secured to the landside, preferably by asingle bolt or rivet, 0, its rear upper corner being bent into a notch or recess,e,

in the landside to prevent its turning on the bolt. This colter has a downwardly-projecting point, (I, which extends beyond the base of the landside, for a purpose presently described. The base or bottom side of the landside is recessed to the rear of the point d for a suitable distance,for the reception of an under cutter or rotary cutting-disl ,E, which is j ournaled vertically to the landside. By reason of the recess in the bottom of the landside, the face of this cutter comes flush with its bottom side. The shaft or j onrnal of the cutter may pass directly through the landside and be held in place by a set-screw, F, as shown in Fig. 1,

or it may be journaled in a bearing, G, which is attached by bolts to the inner side of the landside. This hearing has side wings to permit the passage of bolts through openings formed therein. and an enlarged chambered head, 9, for the reception of a suitable lubricant or cotton or similar absorbent substance satu rated with oil,by which the journal H of the cutter may be kept lubricated. The journal has an enlarged portion or head, h. to guard against its dropping from the bearing.

A strengthening-disk, f,is interposed between the cutter and the end of the journal. The under cutter or rotary disk E is journaled just I in the rear of the point (I of the colter, and

projects laterally from the landside, and diminishes from the friction thereon, besides 7 5 cutting the roots which ordinarily cling to the sod or earth, and is the cause of the unsteady and jerking motions often experienced when plowing. By having the colter project be yond the cutter E, as at d, the roots are not only cut laterally but vertically, thus making a clean cut in both directions.

The mold-board is composed of side bars,I, between which are journaled rollers J. The bars I are attached to the share-bar, and eX- tend rearwardly in an upward and outward direction, following the contour of an ordinary mold-board. Adjustable brace-bars i regulate the sweep of the mold-board and fix its position. The rollers J have a sleeve or bushing, 0

j, interposed between it and its journal K, to

reduce the frictiomand their ends are reduced to cntera recess in the supporting-bars,which prevents the ingress of the earth between the wearing parts of the rollers and their journals. 9 5

Suitable handles, L, are attached to a projection by a bolt, Z, and are braced by rods M.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination of a landside, an under cutter projected laterally therefrom, and a oolter attached to the landside, and having a cutting point projected beyond the plane of 5 the under cutter, as and for the purpose specified.

The conibination,in a plow,of a landside recessed on its bottom side, a rotary cutter journaled vertically to the landside and 10- IO cated within said recess, and a colter attached to the landside and having a cutting-point projected below the plane of the rotary cutter just in advance thereof, substantially as described, and for the purpose specified.

15 3. The combination of the landside, a bear- GEORGE M. NEEDLES. ERNEST G. FISHER.
