SPECIFICATION forming part of Letters Patent No. 715,178, dated December 2, 1902.

Application filed December 5, 1901. SerialNo. 84,791. (No model.)

To CLZZ/ whom it may concern:

Be it known that I, GEORGE WASHINGTON TOLER, a citizen of the United States, residing at Greenville, in the county of Yell and State of Arkansas, have invented a new and useful Cultivator, of which the following is a specification.

This invention relates to cultivators.

The object is to present a cultivator for use in cultivating corn, cotton, or the like in which provision shall be made to cause effective removal of weeds, grass, duc., and for supplying clean earth tothe furrow, at the same time breaking up or dividing the earth, thereby to prevent baking, to provide suitable means by which the disks or cutters'and also a roller used in connection with the device may be held at the predetermined or desired adjustment, to provide means by `which the scraper may be adjusted with relation to the disks or to the roller independently of either, and generally to provide a simple, thoroughly effective, and durable form of cultivator.

The invention consists in the novel construction and combination of parts of a cultivator, which will be hereinafter fully described and claimed.

Generally stated, the cultivator characterized by my invention comprises, in connection with a wheel-supporting frame, two sets@ of disks oppositely convexed with relation to each other, the disks being adjustable about a verticalaxis atright angles to their supports, a scraper arranged in front of each set of disks and adjustable with relation thereto, thereby to cause the scraper to be rendered coperative with the disks irrespective of the character of furrow cut, and a roller arranged at the rear of the disks andA adjustable independently of the disks and the Scrapers, the object of the roller being to overcome side draft and to press down the loose earth, thereby to retain moisture.

In the general construction of the cultivator the supporting-frame and adj uncts usually appertaining thereto may be of any preferred construction and therefore need no specic description.

The invention resides in the coperative relation effected between the Scrapers, the

disks, and the rollers and the means by` which either or all of these may be adjusted independently' to render the device thoroughly operative under all circumstances.

In the accompanying drawings, forming a part of this specification, in which like numerals of reference indicate corresponding parts, I illustrate a form of embodiment of the invention, it being understood that some of the ideas may be carried into effect in other ways without departing from the spirit of the invention.

In the drawings, Figure I is a View in perspective, taken from the rear of the machine. Fig. 2 is a view in side elevation. Fig. 3 is a view in plan. Fig. 4 is a detail view of one of the Scrapers. Fig. 5 is a detail perspective view of the disk-carrying yoke and the roller-carryin g yoke,showing the clutch mechanism for holding the two yokes in adjusted position with relation to the supportingframe. Fig. 6 is a longitudinal sectional detail view of the disk-carrying yoke.

Referring to the drawings, l designates an arch, and 2 an axle, the latter carrying supporting-wheels 3, as usual. The axle may support the tongue, seat, and other parts common to the frame of an ordinary cultivator, and as these form no part of the present invention description is deemed unnecessary.

The supporting-frame of the cultivator mechanism comprises two beams or bars 4, suitably secured' to the arch l, and as the mechanism carried by each bar is the same a description of one will serve for both.

Working in a suitable guide 5 on the beam 4 is a standard 6, carrying a scraper 7, the

scraper being, in effect, an ordinary moldboard without a landside. n In other words, in operation it performs the function of a scraper pure' and simple and not that of a plowshare. The scraper is secured to the standard at an angle to the bar, as usual, and is mountedfor adjustment in the arc of a circle-that is to say, is capable of a vertical 'lting adjustment 'transversely ofthe device-thus to cause the cutting edge 'of the scraper either tolie parallel to the ground or at an angle thereto. To effect this, the scraper is provided with a series of openings 8, arranged in the arc of a circle, a bolt 9, passing through one of the openings, serving to hold the scraper in the desired adjustment. Normally the inner edge of the scraper is at an IOO ` scraper.

angle to the faces of the disks, so that the grass, weeds, or the like detached by the scraper will be thrown to one side. lt will be observed that in addition to the series of openings 8 there are two other openings 10, one of which is permanently engaged by a bolt 1l when the scraper is adjusted for ordinary use; but should it be' desired to bring the inner edge of the scraper parallel with the standard the bolt 11 will be removed from the opening shown and the scraper moved to one side to bring the other opening opposite that in the standard, and the bolt 11 may again be inserted, and the scraper thus held in its adjusted position. The standard is provided with a plurality of openings 12 to be engaged by a bolt 13, passing through the guide on the side of the standard, this ar- -rangement being provided for effecting vertical adjustment of the scraper. On the opposite side of the beam to that occupied by the standard 6 is another guide 14, engaged by a standard 15, the lower portion of which is bent approximately at right angles to its length and supports the disk-carrying yoke 16. The standard 15 is provided with a plurality of openings 17 to be engaged by a bolt 1S, carried by the guide 14, this arrangement being employed to eifect the vertical adjustment of the disks irrespective of the The manner of connection between the yoke 16 and the standard 15 is to be such that when the yoke is adjusted to cause the disks to occupy the desired angle with relation to the furrows the yoke will be held in this position. Several forms of device may be employed for this purpose, and that shown herein is illustrative of one arrangement that will be effective in operation and readily applied for use. It consists in providing the bottom of the standard with a serrated face 19 to engage with a similar face 2O on the upper surface of the yoke, a bolt 21 passing through the lower portion of the standard 15 and the yoke to clamp these two serrated surfaces together. It will be observed by reference to Fig. 8 that the yoke 16 is provided with a plurality of openings 22, each opening being surrounded by one of the serrated faces 20, above referred to.. By this arrangement when the yoke is moved to the desired angle it will be firmly held in position against shifting. On the inner side of the bar is secured a fender 23, the function of which is to prevent the disks in operation from covering up the small corn or cotton.

Carried by the yoke 16 is an arm 24:,which may be slightly resilient, this arm to be fixed to the yoke 16 in such manner as to move therewith. The arm 24 carries a yoke 25, provided with a plurality of openings 26 to be engaged by a bolt 27, the manner of holding the yoke 25 in rigid connection with the arm 24c being preferably similar to that described in connection with the holding of the yoke 16 rigid with the standard 15. The yoke 25 carries a roller 28, the function of which is to press down the loose dirt that has been cut up by thedisk, thereby to prevent escape of' moisture.

In the operation of the device the scraperblade scrapes and loosens the surface of the soil and at the same time cuts and sheds the vegetation toward the outer side of the device, so as not to choke the barrow-disks which are tracked in rear of the scraper and act to cut or chop the loosened soil, and iinally the roller 28 passes over the finely-pulverized soil, so as to pack or press the same and thereby prevent the escape of moisture.

It will now be understood that the present device is intended to break up and pulverize a comparatively thin surface layer. of the soil, and for this reason employs a gang or plurality of comparatively small disks which travel in the track of the scraper and act upon the soil which has been loosened by the scraper, wherefore it will be understood that the device is not intended for and is also incapable of turning a furrow, but is arranged to break up or pulverize a thin surface layer of soil.

In some sections of the country where there is what is known as black-wax landthat is to say, a soil that is heavy and sticky-the scraper may be removed and a second series of disks, carried by a suitable standard, be placed in front of the usual disks and held in place by the guide occupied normally by the scraper. It will be understood that the disks will be oppositely conveXed, so that IOOr one set of disks will throw the earth from the cotton or the like and the other to the cotton or the like, the fender in the manner described preventing any covering up of the cotton or corn.

It will be observed by the manner in which the differents parts are assembled with relation to the supporting-frame that each part is adjustable independently of the other, and by this manner of arrangement all conditions arising in the use of such a cultivator will be provided for. Although not shownin the drawings, l contemplate providing scrapers to remove accumulations of soil from the disks and the covering-rollers when the cultivator is being used upon heavy and sticky soil, said Scrapers to be of any well-known or preferred form.`
