Patented Aug. 28, 1906.

Original application filed June 26,1903, Serial No. 153,265. Divided and this application led April 26, 1905. Serial No. 257.497.

To all whom t may concern.'

Be it known that I, SAMUEL V. WEEKS, a citizen of the United States, residing at Hi hland Park, in the county of Hamilton an State of Tennessee, have invented a new and useful Convertible Plow, of which the following is a specification.

This invention relates to a convertible plow of that general type disclosed in my copending application, Serial No. 163,265, filed une 26, 1903, of which the present application is a division.

The primary object is to provide in a plow of this character a frame comprising separate interchangeable furrow opener supporting beams detachably secured together and equipped with supporting-wheels adapted to sup ort one of t e beams or the frame inclu ing a lurality of such beams in order that the p ow may be readily converted for use as a smgle plow or as a gang-plow includmg two or more units.

A further object is to dispense with the spacing-blocks, devices, and brackets usually employed by providing the interchangealilc furrow-opener-supportmg elements or beams with overla ping portions detachably secured direct y together, so as to permit the conversion of a gang-plow into a single plow by detaching the superfluous beam or beams.

A further obj eet of the invention is to facilitate the turnin of sharp or` square corners by automatical y effecting the proper relative adjustment of the several supportingwheels when the line of draft is changed, this end being attained in the present construction by establishin an operative connection between the shiftab e wheel-supports and the draft appliance.

One embodiment of the invention by means of which the several objects are attained is illustrated in the accompanyin drawing and will be hereinafter descr1be and claimed.

In the drawing is disclosed a plan view of a plow constructed in accord ance with my invention.

What may bc termed a "front wheelframc o', having attached thereto a tongue and sup orted by a front furrow-wheel c, is

his post is received within a cylindrical socket e, formed at the front end of a furrow- Opener-supporting beam f of angular form.

character of )low element or furrow-openery may be substitutedlfor the disk and supported in any desired manner from the rear end of the beam. At the angle of the beam f is located a vertical post i, similar to the Yost d ofthe front wheel-frame a. This post is received within a cylindrical socket e of a second furrow-opener-sup orting beam or diskcarrying element f, wliich is a duplicate of and interchangeable with the beam At its rear end the bcamf carries a furrow-opener g, and at its angle rises a post h', identical in mmstruction and location with thc post h of the beam f. The two beams and disks connected as specified constitute a gang; but it will of course be understood that this series of beams and furrow-openers may be extended indefinitely, it being merely necessary to provide any additional number of units constructed recisely like those described and connectetlhn a similar manner. To thc last beam of the series or gang, in the present instance the beam j" is applied the rear wheelfranie i, sup orted at its front and rear ends by the lan -wheel k and the rear furrowwheel j. At the front end of the rear wheelframe i is formed a socket m, which receives the post h of the beamf. The several )osts d, h, and h are each cut away at one si e, as indicated at to accommodate a lug y, projecting inwardly from the socket within which the post is received. By reason of this arrangement the front wheel-frame is ermitted to have limited pivotal movement independently of the beam f with the post d as an axis, each beam similarly having slight relative movement independently of the beam in rear thereof and the rearmost beam being similarly movable with reference to the rear wheel-frame i.

The crank-axle n of the land-wheel is swiveled in the rear wheel-frame i, as shown, and is connected, as by a chain 0, to the adjacent end of the front wheel-frame ai. The rear wheel-frame is connected at the inner side of its axis to the front wheel-frame by a chain which may be given direction by a suitabiiz guide p', adapted to be detacha 1y connected to any one of the several beams, but shown connected to the beam f. It will IOO be noted that in making a turn to the left the front wheel-frame will turn slightly before being arrested by the engagement of the stop i with the rear shoulder on the post d. The fiont wheel-frame and the beam f will then swing in unison with the post t as an axis, the beam j" being then similarly swung relative to the rear wheel-frame, and all of these elements of the plow-frame assuming their normal relation, as shown in the drawing, as soon as the turn is completed. In making a turn to the right, however, there is no relative movement of the elements of the plow-frame, since the lugs y are normally in engagement with the front walls of the cutaway portions :1; of the several posts. The vertical adjustment of the frame comprising the beam elements relative to the front and rear wheel-frames is effected by means of levers r and s. The lever r is fulcrumed on a toothed segment r', adapted to be bolted, clamped, or otherwise secured to whichever of the beams occupies the most advanced position. In the present instance this segment is shown attached to the beamf.

At its front end the lever r has loose pivotal connection with a bracket r2, secured to the post d. Obviously by swinging the lever r the beam f may be raised or lowered relative to the front wheel-frame, the lever being secured in its adjusted position by means of a latch r3, carried by the lever and engaging the segment. The lever s is fulcrumed upon a toothed segment s', secured to the rear wheel-frame adJacent to its front end, the front extremity of the lever having loose pivotal connection with whichever beam occupies the rearmost position#for instance, the beam The lever s is equipped with a latch s2, w ich en a es the segment s. By the manipulation o tiis lever the rear end of the beam may be raised and lowered relative to the rear wheel-frame. The spring g' of the drivers seat q is bolted or otherwise secured to the rear end of the rearmost beam, as shown in the drawing, when the plow is organized as a gang, and is similarly at- .tached to the single furrow-opener-supporting beam when the device is converted into sin le plow. V

t will be observed from the foregoin f that I have produced a plow including a rame comprising separate interchangeable overlap in furrow-o ener-supporting beams detac ab y secure directly to ether and carried by supporting-wheels, al of which are capable of attachment to one of such beams alone or to the frame including a plurality of such beams to permit conversion from a vang to a single plow or vice versa. It is to be understood, however, that while the present embodiment of the invention is thought at this time to be preferable I reserve the right to effect such changes, modifications, and variations of the illustrated structure as may come fairly within the scope of the protection prayed.

What I claim isl. In a convertible plow, separate interchangeable furrow-opener-supporting beams having overlapping portions flexibly and detachably connected to permit conversion from a single plow into a gang-plow and vice versa and to enable the beams to move laterally relative to each other when the device is organized as a gang-plow, and means for limiting such relative movement of the beams.

2. In a convertible plow, a frame comprising separate interchangeable furrow-openersupporting beams detachably and flexibly connected, stops for limiting relative lateral movement of the beams, and supportingwheels, all of which are capable of attachment both to one of the beams alone or to a frame including a plurality of such beams.

3. In a convertible plow, front and rear wheel-frames, a front furrow-wheel supporting the front wheel-frame and a rear furrowwheel and a land-wheel supporting the opposite ends of the rear wheel-frame, and separate interchangeable furrow-opencr-supporting beams connecting the wheel-frames and also directly connected to each other.

4. In a convertible plow, a front wheelframe disposed directly across the line of draft, a rear wheel-frame disposed obliquely across the line of draft, a su porting-wheel for the front wheel-frame, a p urality of supporting-wheels for the rear wheel-frame, and a plurality of separate interchangeable furrow-opener-supporting beams detachably secured together and connecting the front and rear wheel-frames, each of said beams being adapted for attachment to a plurality of similar beams or to either the front or rear wheel-frame or both, whereby the low may be converted from a gang to a sing e plow or vice versa.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

SAMUEL V. WEEKS.
