SPECIFICATION forming part ef Lettereyratent No. 53o,879, dated Deeember 11", 1 894-.

Appleman ined April 1s, 1894.. seria No. 507,422. (No medew To all whom it may concern:

Be it known that I, JAMES V. BRADY, a citizen of the United States, residing at Sonora, in the county of Hancock and State of Illinois, have invented certain new and useful Improvements in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.Vv

This invention relates to cultivators.

The object is to produce a cultivator, in which the teeth or shovels may be adjusted independently of the drag-bars, in groups or pairs, to regulate the depth to which the teeth enter the ground; andl further, in which each tooth may be separately adjusted to adapt the cultivator to the width of therows of the crop. Y

With this and other objects in View, theinvention consists in the combination of parts hereinafter described and claimed.

The invention is illustrated in the aecomclamps, and the toothed Shanks separately and adjustably held by the clamps. Fig. 2-

is a view in side elevation, showing a crossbeam adjustably held on the drag-bar and the toothed shanks clamped to the beam, also, the relative lengths and arrangementof the Shanks. Fig. 3- is a view in front elevation of one of the slotted cross-beams, showing the stirrup-clamps adj ustablyseated in the slots, and a set-screw or bolt passing through an enlargement of the beam to a vertical, central opening and binding against the drag-bar therein. same, showing the slots in the beams and the threaded extremities of the U-shaped clamps projecting through the slots and provided with lock-n uts. Fig. 5 is a fragmentary view showing a modied form, in which the central enlargement of the beam is chambered to receive the curved end of the drag-bar which is slotted laterally and held by binding screws or bolts passing laterally through the enlargement and the slots, above and below l the other partv of the beam, the construction Fig. 4- is a top plan view of thevand arrangement permitting Aslight play of the beam. v y v In the drawings, A, represents the dragbars of a cultivator, the rear ends, a, a, of which are flattened and curved downward.

B, represents slotted cross-beams which are respectively provided about midway of their length with an enlargement, b, projecting vertically from opposite sides of the beam, at a right angle thereto. This enlargement is vertically and centrally bored at b2, to receive the curved extremity of the drag-bar to which the beam is adjustably connected by a binding screw, bolt, or other device, h3.

C represents stirrups, yokes, or U-shaped clamps, which are adj ustably seated in perforations or the slots, b4, toward the outer ends 'of the beams, with their curved portion projecting through the slots and below the lower face of the beams, and their extremities threaded to receive lock-nuts, c, c.

D, represents curved toothed Shanks, here shown arranged in pairsor twooneach beam. These shanks areisepa'rately securedfto the under side of the beam, bybeing passed.

through the depending stirrups, andare adjustablyl heldl by the lock-nuts, c, c, either rigidly or yieldingly, as desired. One shank of a pair is given'an increased length by which the shanks may be relatively adj usted to work in a follow-up series, as shown in Fig. l of the drawings, or parallel, in pairs, or fours, ac-

cording to the number employed.

Where the soil is hard or stony, it may be found necessary to give the cross-beams slight play, and avoid shocks or strains on the teeth. To effect this, the construction illustrated in Fig. 5 is employed, and consists in chambering the central enlargement of lthe beams or makingr it U-shaped, to receive the flattened extremities of the drag-bars, which are of a width sufficient readily to admit of slots being formeditherein, without materially weakening them, and through these slots, screws, bolts, or pins from the enlargement are passed and work loosely therein.

Among the numerous and important ad vantages of this invention may bementioned, the ease and convenience with which an entire rearrangement of the teeth, shovels, or points, may be effected, to adapt the cultivator IOO to perform work of various kinds efficiently; also the connection between the cross-beams and the Shanks, by Which the latter may be Separately and accurately adj usted and rigidly or yieldingly secured.

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

l. The eolnbin ation with a drag-bar, having its rear end curved downward, of across-beam provided about midway of its length with an enlargement having a central vertical perforation or chamber and binding screws or bolts to retain the drag-bar in desired position, and provided, further, with slots toward its ends, and of stirrups or yokes set in the slots with their curved portion downward and having their extremities threaded and provided with nuts, all substantially as and for the purpose described.

2. The combination with drag-bars, having all substantially as and for the purpose set t forth.

In testimony whereof I aftix my signature in presence of two witnesses.

JAMES V. BRADY.
