ED\VARD FOWLER, OF CEDAR GROVE, GEORGIA, ASSIGNOR OE ONE-HALF TO THOMAS B. SIMMONS AND JESSE L. SIMMONS, OF SAME PLACE.

PLOW.

SPECIFICATION formingpart of Letters Patent No. 657,654, dated September 11, 1900.

Application filed February '7, 1900. Serial No. 4,418. (No model.)

To n/ZZ whom t may concern,.-

Be it known that I, EDWARD FOWLER, a citizen ot' 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.

This invention relates more particularly to disk plows; and it consists of certain improve to ments, which will hereinafter be more fully set out.

In the drawings, Figure 1 is a perspective view looking toward the front of the lower portion of a plow embodying my invention.

I5 Fig. 2 is a diagram illust-rating the angular set ot' the disk. Fig. 3 is a perspective view of the journal-bearing and carrying-bar of the disk, and Fig. at is a cross-sectional View' of the saine.

2o The plow-beam has a downwardlyv and forwardly extending' standard 2, said beam and standard being substantially I -shaped in cross-section. The standard is provided with a series of bolt openings or holes 32 The runner or landside is secured to the foot of the standard adjustably, as shown and described in my application above referred to, while the shin-board 4 is of a construction shown and described in an application iiled 3o by me of even date herewith, said board being provided with a shoulder 5, to be hereinafter referred to.

6 is a plate provided with an elongated lug or projection 7 on its rear face at each end,

between which is formed a waved portion S, said plate being provided at each end with bolt-openings 9.

10 is a journal secured to the plate 6 in any suitable manner, said bearing being ta- 4o pered from end to end.

l1 is a V-shaped groove or notch cut in the wall of the bearing 10, which is a continuation of the groove 12, formed in the plate 6. 13 is a groove formed in the plate 6 around the larger end of the journal-bearing, said groove increasing in depth from end to end.

14 is a journal secured in the journal-bearing 10 by means of the nut 15, and 16 is a disk concaved and secured to the journal 14,

5o the periphery of the disk working against the shoulder 5 of the shin-board, as more fully described in my application tiled of even date herewith.

The plate 6 is secured to the standard 2by means of the bolts 17, passing through the boltopenings 9 at cach end of said plate, the elongated lugs or projections 7 and thegrooves 12 of the plate 6, and the V-shaped groove 1l of the journal-bearing conforming to the outline of the standard 2. The respective grooves 6o in the plate 6 and journal-bearing 10 are out in said members on an angle and at a point that when said plate is secured to the standard as described will set the disk 16 in such position that it (the disk) flares outward from the line of draft to the rear at an angle of forty degrees, while the top of the disk will be at an angle of about twenty degrees to the vertical, and this angle will be retained throughout the vertical adjustment of the 7o disk and plate 6 on the standard 2 by means of the grooves 12 and 11, respectively. The plate 6 being set in a position out of the vertical would have a tendency to twist the journal and the disk in their predetermined positions, and to overcome this tendency Iprovide said plate with the groove 13, increasing in depth from the bottom toward the top, following the angle of the set of said disk and its journal-bearing. 8o

As hereinbefore stated, the disk 16 is set at an angle of about forty degrees to the line of draft, whereby the furrow is more thoroughly broken up and turned. It has been found in actual practice that a disk set at the angle stated gives the earth a boiling action, thus rendering this plow especially effective in turf-land. The disk leans backward at an angle of about twenty degrees to a vertical plane, thereby causing the disk to suck or 9o draw under the ground when in operation. This drawing or sucking action is especially desirable in hard or turf land, inasmuch as it holds the plow down on the bottom of the furrow without extra labor on the part of the operator, thereby dispensing with the eXtra weight-that is now utilized in disk plows Yfor holding-down purposes.

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

1. In a plow of the character described, the combination with the standard of a plate having grooves extending lengthwise, a journalbearing securedy to said plate, and a Vshaped groove formed' in the outside of said bearing as a continuation `of one of the grooves on said plate.

2. In a plow of the character described, the combination with the standard of aplate adj ustablysecured on thesame, a journal-bearing secured on said plate tapering from end to end, a groove increasing in depth from end to end formed around the larger end of said bearing and a journal carrying a disk.

3. In a plow of the character described, the

Combination with the standard of a plate adjustable on said' standard, grooves extending lengthwise of said plate, a journal-bearing secured to said plate, a V-shaped groove formed in the outside of said bearing as a continuation of one of the grooves on said plate and a groove increasing in depth from end to end formed around one end of the journal-bearing, and a journal carrying a disk.
