IMPROVEMENT, -|N CULTIVATORS.

Specification forming part of Letters Patent No. 184,042, dated November 7, 1876; application filed I v March 8, 1876. V

To all whom it may concern:

Be it known that I, ALMON HUNT, of Macomb, county of McDonoughjand State of Illinois', havejinvented certain Improvements in Cultivators; and I hereby declare thefollow' ing to be a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawing, making part of this specification, and in which- Figure 1 is a perspective view of a cultivator embodying my invention. Fig. 2 is a rear elevation of the axle, and sectional view through the axle-section-conneoting sleeve, and through the sleeves to-which the plowbeams are coupled. Fig. 3 isa side elevationnear wheel removed.

This invention relates to improvements in that class .of cultivators known as tongueless cultivators and the invention consists, first, in mounting upon the axle a plate, to which a forwardly-projecting supportingpole for the axle may be attached, for sustaining the axle in an elevated position when the plows are hooked up thereon for transportation upon their own wheels; second, in con structing said plate with stops, and in so attaching the supporting-pole thereto as to limit the inclination of the axle from a vertical position, when the rear ends of the plowbeams are elevated thereon; third, in constrnctingaforesaid plate in theform of a sleeve, with its ends so constructed that they will act as stops to limit the oscillations of the axlesectious in relation to each other, and the consequent relative advanced and receded positions of the plows, each to the other.

Referring to the parts by letters, A represents the axle, made in two sections, A A, each section crank-shaped, and formed of an upper part or journal, a, an elevating or side part, a, and a horizontal part, a. The supporting-wheels B are journaled on the outer ends of the parts a, and sleeves O are also journaled on the parts a, between the wheels B and the angle from which springs the side a. The sleeves C have series of projecting lugs c, to which the-ordinary cultivator-plows D are attached by their beam-plates d, as plainly shown in the drawings. E E are the draft-bars, each having its forward end formed I into a hook, -e, for the attachment of the single-tree, an d the connection thereto of the draft animal, and'itsrear end bifurcated and journaled, an arm at each end of a sleeve,0,and on the part a of the axle. F is a link, its lower end'pivoted to the draft-bar E, and its upper end slotted, as shown in the drawings. f 'is a'guide-bolt projecting from-the part a of the axle, through the-slotted links E, and provided with a head on its outer end. G is a tubular sleeve, receiving the ends a of the axle, and provided at each end with downwardly enlarged and projecting plates 9 in close proximity to the parts a of the axle on their inner sides. to each plate g by means of studs h, of such length as to bring the plates 9 H snug to the sides of the arm a, but still to allow it to slide between them, and of such distance apart as to act as stops to limit the inclination of the axle when the plows are suspended thereon, and to properly limit the advance of each plow relatively to its fellow. I is a supporting-pole, and has two braces, t, pivoted at one of their ends to near its rear end, and their other ends formed into hooks t". J is a loop or eye attached to one side of the sleeve-coupling G, and perforated to receive an eyebolt, j.

The pole I may be readily put in place by inserting its rear end in the eye J and inserting the eyeboltj, and engaging the hooks t" in holes 9 in the plates g, and may be as readily and easily removed.

K K are studs projecting from the plates G, and over which the hooks L, attached to the plow-beams, may be hooked to suspend the plows.

In operation in the field the pole I is removed, and the draft-animals attached to the draft-bars E. As either animal advances ahead of its fellow the wheels B are retained in the line of progression by means of the sections A of the axle oscillating in the sleevecoupling G and changing positions, as shown at Fig. 3, where the near section A is shown with its attached plow advanced, and the other section receded, and the extent of movement of this kind is also. shown, the stops h striking the arms a, and thereby limiting the His a plate, connected one same. The slotted-arms or braces F, it will be seenfrom Fig; 3, allow the draft-plates E to retain their position wliile'the vertical angle of the sides a of the axle are changing, and while the positions of the arms a are fixed they allow the forward ends of the draft-plates E to be raised or lowered in the obvious manner, and the rear ends of the slots striking the bolts f will retain the bars E from dropping much below a horizontal position.

The lateral and vertical --movements of the rear ends of the plow-beams, independently of each other, are obtained in a usual manner by movement-on the lugs 0, and movement of the, sleeves O on the axle a, respectively.

For the purpose of transporting the machine on its own wheels B, the supporting-pole l is put in place, and by means of an ordinary neck-yoke connected to the necks of the draftanimals. The rear ends of the plows being then elevated, the hooks L may be hooked over the studs K, and both sections A A of the axle will assume the position shown by the near section at Fig. 3, at whichposition,

the stops h engage the arms a of the axle, and limit further movement without raising the forward end of the pole I. When the set forth.

2. The sleeve G, having plate 9 H on its ends, and stops it operating, in combination with the detachable pole I, axleA, and plows D, having hooks L for engaging studs K, substantially as and for the purpose specified.

3. The sleeve G, having plates g H, and

stops h between the plates, operating incombination with thesectionsA A of a divided axle to hold them in place and limit theirmotion, substantially as and for thepurpose specified.

ALMON- HUNT.
