JOHN AUSTIN, or CHICAGO, ILLINOIS.

ROTARY PLow.

SPECIFICATION forming part of Letters Patent No. 291,127, dated January 1, 1884.

- Application filed-May 16, [883. (N0 model.)

To aZZ whom it may concern Be it known that I, JOHN AUsTIN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rotary Plows, of which the following, in connection with the accompanying drawings, is a specification.

In the drawings, Figure 1 is atop or plan view of a rotary plow provided with my improvements. Fig. 2 is a side elevation of the same. Fig. 3 is a horizontal section in detail, representing the construction of the disk-hub and its relation to the disk axle or spindle. Fig. 4 is a side View of the flexible washer. Fig. 5 is a rear view of a part of the frame, showing the connection therewith of the tilting draft-wheels and the means employed for tilting them. Fig. 6 is a side view of one of the sides of the rotary disks, partly broken away to more fully show the construction of the same. Fig. 7 is a side view of one of the flanges forming a part of a rotary-disk, and Fig. 8 is a section in the plane of the line as x of Fig. 6.

Like letters of reference indicate like parts.

My invention relates to that class of plows provided with rotary disks for laying the furrows, and in which the said disksare set at an angle to the line of draft. In the example shown I have represented a sulky gang-plow -.of the class referred to.

A represents the frame of the plow.

B is the draft-tongue, which is attached to p the forward part of the frame A, and rigidly connected thereto by means of the braces a a.

O is the king-bolt. D is the drivers seat.

E is a crank-axle, arranged diagonally and turning. in suitable boxes or bearings applied to the frame A.

FF are rotary disks, one of which is ap* plied to the spindle of the axle E.

G is the hub ofthe disk F, and G is a concavo-convex flange extending laterally from the rear endof the hub G, and cast or made in one and the same piece therewith. This flange has a rim, 1), having a curvature difierent from that of the body of the flange, as is clearly indicated in Fig. 1; and c c are pocket-s so or depressions setting back from the flange G,

as is clearly indicated in Figs. 6 and 7, and also in Fig. 8.

v H is an annular blade, made in sections, and bolted or otherwise securely fastened to the rim b. Theedges of these sections meet or nearly meet in the perimeter of the disk, but diverge from each other from their outer eorners inward, as shown at (Z d, and the pockets or depressions c 0 lie directly behind the spaces or openings between the radial edges of the sections of the disk H. These sections are somewhat dishing in form, as shown. The in terior of the inner end of the hub G' fits upon a collar-band, e, on the spindle of the axle E.

I is an annular piece of rubber stretched over the collar 0, and located behind it. This annular piece I clamp to the flange G bymeans of a ring or annulus, J. I retain the disk F upon its spindle by means of a screw, K, passing freely through the outer end of the hub G and screwed into the end of the spindle, as shown in Figs. 1, 2, and 3. I construct and apply the disk F the same as the disk F, excepting that it rotates upon a fixed spindle rigidly applied to a supplemental frame hinged to the main frame, as will-hereinafter more fully appear.

L L are shears attached to arms rigidly applied to the frame, and arranged to shear against or with or nearly against the working-face of the sectional parts of the disks F and F.

M is an arm or lever rigidlyattached to and projecting forward from the axle E, and N is a lever pivoted to the frame A. The lever N has two arms or branches, f and f, and the latter is connected at its forward end to the forward end of the arm or lever M by means of a link, 9.

O is a segmental arch rigidly attached to the frame A, and having in it the holes or openings h h. I set the lever N in different positions, and lock it temporarilyby means of apinpass ing through it and into one or another of the openings h h. By this means the axle E may be adjusted rotatively, with the result hereinafter referred to.

P is a lever, pivoted at 13 to an arm or support, Q, attached to the frame A. The forward end of the lever P is connected to the rear end of the arm f of the lever X by means of a link, j.

A is a supplemental frame hinged to a rear cross-bar, B, forming a part of the frame A, and C is a spindle rigidly attached to the frame A. The disk F is mounted upon the spindle O in like manner as the disk F is mounted on the spindle G, but is located to turn a furrow adjacent to that turned by the disk F, as is clearly indicated in Fig. 1.

It is an upright rigidly attached to theframe A. The rear end of the lever P is connected to the upright 11 by means of a link, S. By this means the frame A, and hence the disk F, may be set either higher or lower by adjusting the lever end for that purpose, and both disks F and F will thus be either raised or lowered simultaneously.

T T are the draft-wheels, and D D are independent axles upon which the said wheels are mounted.

E is a segmental arch applied to or forming a part of the bar B, and k 7; are holes in the said arch.

F is a T-levcr, pivoted to the bar B at the junction of its vertical and horizontal arm.

H H are links connecting the inner ends of the axles D D to the ends of the shorter or horizontal arm of the lever F. The lever F is capable of being tilted or inclined laterally and locked temporarily by means of a yielding lever, F, pivoted thereto, and pro vided with a pin, Z, passing through it and entering one or the other of the holes k k removably. I make the bar B, by preference, of two parts or parallel pieces bolted together, but far enough apart to allow the lever F, axles D D, and links H H to play or move between them as the lever F is adjusted. I bolt or otherwise securely connect the support Q to the arch E.

In some respects the plow now described is similar in construction and operation to plows of the same class heretofore constructed. For example, the plowing-disks are dishing and set in. planes diagonal to the line of draft, and are also arranged so that one will lay a furrow in advance of the other, and are adjustable.

This invention relates, principally, to the construction of the plowing-disks and to the means employed for so inclining the draftwheels as to resist the lateral presssure of the soil upon the disks, and also for regulating the depth of the furrows. To tilt the wheels T T, I move the lever F in the direction i11- dicated by the arrow shown in Fig. 5, and lock it temporarily in the posit-ion so set, in the manner already described. It will be perceived, on reference to the said figure, that the wheels T T will be inclined or so set as to resist the pressure exerted upon the plowing-disks, and hence cause the plow to travel properlybehind a team, so as to lay the furrows in the direction desired. It will also be perceived that the whole plow-frame and plowing-disks will be lowered in proportion to the inclination of the wheels T T, thus causing the furrows to be deep or shallow, as may be desired. The deeper the furrows the greater will be the lateral pressure, under ordinary circumstances, and when the depth of the furrow is regulated by the depth of the wheels T T their inclination will correspond to that pressure; but, as will also be perceived, I have made provision, through theinstrumentality of the lever N and its connections, for adjusting the plowing-disks vertically independently of the means employed for inclining the wheelsT T. It will also be observed that while one wheel T runs in the furrow and the other upon the unplowed ground, the frame will be supported horizontally, owing to the fact that in tilting the said wheels the outer end of the hub of the furrow-wheel moves downward and the outer end of the hub of the land-wheel moves upward.

In constructing the disks F and F in the manner described, I aim to prevent them from becoming clogged, and also to shut out sand or grit from the spindles on which they turn, and in endeavoring to accomplish these results I have also aimed to employ such fea tures of construction as would render the making of the disks comparatively cheap. It will be perceived that the fine or broken soil which otherwise might remain upon the working-faces of the disks will pass through the spaces (1 (1 into the pockets 0 c, and thence fall out at the back of the disks as the latter are rotated. By making the hub G-andflange G in one and the same piece, the ends of the hubs and the screws K K covering the ends of the spindles, as shown, the grit and dirt are prevented from there passing in between the hubs and their spindles, and the flexible diaphragms or rings I I shut out the dust and grit from entering the opposite ends of the hubs.

I am aware of the construction shown and described in United States Letters Patent to A. J. Manny, K0. 50,018, wheel-cultivators, September 19, 1865; J. \V. Surta, No. 112,394, March 7, 1871, gang-plows, and J. Nicewood, No. 257,603, May 9, 1882, sulky-plow, and I do not therefore here intend to claim the same; but,

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

1. The combination, substantially as specified, with the frame of a rotary plow having a diagonally-arranged plowing-disk. of the draft-wheels T T, the vertically tilting sectional axles D D, carrying the said wheels and pivoted to the said frame, and an adj usting-lever jointed to the said axles,for the purpose of thereby admitting of the said wheels being both inclined laterally in the same direction by means of the same lever.
