CHARLES HENRY RUDDELL, OF TERRELL, TEXAS.

CU LTIVATOR.

SPECIFICATION forming part of Letters Patent No. 404,437, dated .T une 4, 1889.

Application filed November 27, 1888. Serial No. 292,031. (No model.)

To all whom t 71mg concern:

Be it known that I, CHARLES HENRY RUD- DELL,-a citizen of the United States, residing at Terrell, in the county of Kaufman and State of Texas, have invented new and useful Improvements in Cultivators, of which the following is a specification.

My invention relates to improvements in cultivators; and it consists in certain novel features hereinafter described and claimed.

In the accompanying drawings, Figure l is a perspective view of my improved cultivator. Fig. 2 is a side view of the same, showing the scraper attached to the rear side of the crossbar. Fig. 3 is a detail view of the standard adapted to support a shovel-plow.

Referring to the drawings by letter, A designates the main beam, provided with a clevis at its front end of the usual or any preferred construction, and having the standards B B secured to its rear end on its opposite sides, as shown.` The handles C C are detachably secured at their front ends to the opposite sides of the main beam and extend upward and rearward therefrom, and are suitably braced by the rung D, which is mounted in the upper ends of the standards B B.

E E designate two obliquelyarranged clamping-bars, which are secured to the under side of the beam, near the rear end of the same, and are provided with the notches F in their inner meeting faces, which are engaged ,by the angular Shanks G of the cultivatorteeth H, as clearly shown. These clampingbars are secured together by the transverse bolts I, as shown. To the rear side of the rear clamping-bar and at the ends of the same I secure the blocks J J, for a purpose presently specified.

K designates a scraper, consisting of a continuous metallic plate concave on its front face and provided near its upper edge and at its ends with a series of openings L, and also provided at one end with -the upwardly, proj ccting lip M.

N N designate hangers, which have their upper ends provided with a series of openings O, through one of which securing-bolts P are passed into the front clamping-bar E. The lower ends of these hangers are secured to the scraper by means of bolts passed through the` proper opening L and the lower end of the hanger, as clearly shown. The scraper is strengthened by means of the bracerods Q Q, which have their rear ends secured to the lower ends of the hangers by the same bolts which secure the hangers to the scraper and their front ends bolted to the main beam A, as clearly shown.

In Fig. 3 I have shown a standard adapted to carry a shovel-plow. The said standard is angular in cross-section and its lower portion is flattened and provided with a transverse shoulder R, against which the upper edge of the shovel abuis, and a longitudinal slot S, through which the securing-bolt is passed to adjustably secure the shovel to the standard.

In practice the cultivator is drawn over the iield at the side of the row of plants with the scraper in advance of the teeth, as shown in Fig. l, so that as the device is drawn along the scraper will level the ground and will cut off the weeds and direct them to the side of the row. The lip at the inner forward end of the scraper will take into the ground, and thereby aid in guiding the machine. By reason of the openings in the scraper the same can be adjusted so as to run closer to or farther from the plants, as may be desired, and by means of the openings in the hangers the scraper can be adjusted so as to run to a greater or less depth, as will be readily understood.

If so desired, the hangers can be removed from the front clamping-bar and secured to the blocks J on the rear side of the rear clamping-bar, so as to run in rear of the cultivatingteeth, thereby throwing the loose soil cut up by the cultivator-teeth toward the row of plants, so that the same will be piled up around the roots.

By having the cultivator-teeth run deeper in the ground than the scraper the device is prevented from twisting to one side as it is drawn over the field, thus overcoming a serious objection to the Scrapers heretofore employed.

The cultivator-teeth can be readily adj usted to cut to any desired depth,.or they may be raised entirely, so that the device can be used as a scraper alone, or the scraper may be detached, so that it may be used merely as a cultivator.

The front ends of the handles are secured IOO to the beam by a single bolt, and the lower ends of the standards B B are also secured to the beam by a single bolt. ly removing the bolt which secures the handle they can be moved forward or rearward, so that their rear ends will be :raised or lowered; as may be desired.

The cultivator-teeth may be provided with square or angular points, as may be desired, and one or more shovel-plows may be used with the cultivatoisteeth.

From the foregoing description, taken in connection with the accom panying drawings, it is thought t-he manner of using my device and the advantages of the same will be readily understood without further detailed reference thereto.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination of the main beam, the clamping-bars secured to the under side of the beam and arranged at an angle thereto, the teeth clamped by and between said bars, the

hangers having their upper ends adj nstably secured to the ends of the clamping-bars, and the scraper secured to the lower ends of the hangers, as set forth.

2. The combination of the beam, the clamping-bars secured to the under side of the beam and arranged at an angle thereto, the teeth clamped by and between said bars, the hangers having their upper ends provided with a vertical series of openings, the securing-bolts passed through said openings into the ends of the clamping-bars, and the scraper having a horizontal series of openings in each end, and the securing-bolts passed through said openings into the lower ends of the hangers, as set forth.

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

CHARLES HENRY RUDDELL.
