CULTIVATOR.

i n SPECIFICATION forming part of Letters Patent N of 763,288, dated June 21, 1904.

Application led October 19, 1903. Serial No. 177,614. (No model.)

T CZZZ whom, it muy concern,.-

" Be it known that we, MILES JnNNINGs and JOHN H. J ENNINGs, citizens of the United States, and residents of Elizabeth City, in the county of Pasquotanl and State of North Carolina, have made certain new and useful Improvements in Cultivators, of which the following is a speciiication.

This invention is an improvement in cultivators, and especially in straddle-row cultivators, and has for an object, among others, to provide a novel construction of beam and of devices for supporting the same so the different sections of the beams can be readily adjusted in order to set the plows in any desired relation; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure l is a perspective view of a cultivator embodyingl our invention. Fig. 2 is a detail perspective view of a portion of the handle-frame. Fig. 3 is a top plan View of the cultivator. Fig. 4 is a detail perspective view of the clamping devices for the plows and for the wheel-standards. Eig. 5 is a detail perspective view illustrating the devices i'or securing' the lateral arms of the arches in connect-ion with the beams, and Fig. G is a detail section on about line 6 6 of Fig. l.

The cultivator,as shown, comprises the front arch A, the rear arch B, andthe beams C at the opposite sides ot' the implement. The arches A and B are formed, respectively, with the top bars A B', the side arms A2 B2, and the lateral arms A:i B3, said lateral arms being connected with the beams by the devices presently described. The handle is formed with the bars C vand the handle-frame D, having the side bars D secured to the handles C' and the cross bar D2 slotted longitudinally at vits middle at (Z to receive the bolt E, which'passes through the top bar B of the arch B, thence through the slot (Z, and then through an openingin the clasp E and receives the nut (Z. The clasp F over-lies the handle-frame and is provided at its ends with depending lugs f, which extend down alongside the handle-frame and the top bar B oi' the arch and braces the handle-frame in connection with the arch and at the same time permits the adjustment of the handle-frame laterally to any desired eX- tent.

The draft connection, which may be a pole G, as shown, has the arms H, which spread apart at their rear ends and are connected with the lower ends of the sides A2 of the arch A. This connection is preferably effected by means of the brackets I, provided at their upper ends with lugs I', fitting on opposite sides of the uprights A2, bolted near said ends at J to the said uprights A2 and having the arms H bolted to the said members at J near their lower ends'. This forms a convenient connection for the draft devices and permits the latter to be arranged below the lateral arms A3 of the front arch, as will be understood from Fig. l of the drawings. The beams C are secured to the lateral arms of the front and rear arches and are alike except that they are rights and lefts, as will be understood from Figs. l and 3 of the drawings, so that the description of one of the beams and the parts connected therewith will answer for both.

VThe beam C comprises the front section C, the rear section C2, the connecting-bar C3, and the segment C4, by which to secure the front and rear sections C and C2 in any desired adjustment. The front and rear sections are composed of bars of metal bent upon themselves at their middles at one end and lapping at their inner or adjacent ends at 2 upon the bar C3, to which they are secured by the bolts 3 and 4, so the said sections Cl and C2 may be swung to any desired adjustment relatively to each other so that they may be brought into alinement with each other or at any suitable angle within the range of the adjust? ment. By this means the front and rear sections can be adjusted inwardly or outwardly, or one inwardly and the other outwardly, to any desired extent in order to secure the arrangement of the plows presently described to run in any lines desired. This is specially important in cultivatingdiferent crops where they may be planted in rows spaced different distances or where it may be desired to run the plows nearer or farther from the growing plants for any desired purpose. In order to secure the sections C and (J2 in any desired adjustment, we provide the segment C1, which may be secured pivotally at one end by the bolt 4 to the inner end of one of the beamsections and swing at its free end along the other beam-section and be secured to the latter when the parts are set to any desired position by means ot' the bolt as will be understood from Fig. 1 of the drawings. It may be preferred in some instances to tooth or roughen the segment at 6 on opposite sides ot' its bolt-slot 7 in order to give a better hold in clamping the segment in the desired position. By the described construction by the use of an ordinary wrench the nuts may be readily loosened .and the beam-sections set to any desired position and firmly secured in such position.

The front arch has its lateral arms secured to the front beam-sections, and the lateral arms of the rear arch are secured to the rear sections ot' the opposite beams, and the connection is effected by means which permit of the adjustment oi' the beam-sections along' the said arms in securing the diierent adjustments of the beams. As shown, the arch-arms are secured to the beam-sections by the bolts K, having eyes K', receiving the arms A3 and fitting in recessed. blocks L, resting upon the top ot' the bca1n-section,a nut K2 turning on the bolt between the upper and lower bars of the beam, as will be understood f rom Fig. 6 of the drawings. The recessed block L has the recesses L in its upper face to receive the eye K and is notched at L2 in the opposite walls ot' said recesses to receive the arms of the arch, as shown in Fig. 5.

Each of the beam-sections carries astandard M of a shovel M, which may be of any suitable i'orm, and the front ends of the beams are supported by the wheels N, having' standards N connected with the beams, and the said standards M and N are connected with the beams by similar devices, which are shown in detail in Fig. et of the drawings and applied for use in Figs. 1 and 3 and consist of a block O, an eyebolt P, a bearing-plate Q, and a nut R. The block O is grooved vertically in one face at O for the standard and has in said face a recess O2 for the eye P of the bolt P, which latter embraces the standard and draws the same iirmly into the groove O of the block O when secured, as shown in Figs. 1 and 3. rlhe face of the block O opposite the groove O is recessed at O3 to lit the beam, and the bolt P extends through the block O, thence between the upper and lower bars ot' the beam, (see Fig'. 1,) thence through the bearing-plate Q, on the opposite side of the beam from the block O, and receives the nut R, which turns up against the bearing-plate Q, as will be understood from Figs. 1 and 3 of the drawings. By this means the standards may be secured in any desired vertical zuljustment, and the securing devices may be adjusted along the beam in order to set the standards at any desired point along the said beams as may be desired in the use or' the implement.

From the foregoing description it will be understood that we provide an implement in which the beams are composed of sections which may be adjusted relatively to each other and also adjustable along the arms ot' the front and rear arches so the shovels can be set to any desired position and those on the same side of the implement be caused to run directly in line with each other, or the front and rear shovels may be set to any desired relative position in order to secure the movement of the shovels in the desired lines. The shovels c'an also be adjusted vertically independently of the front supporting-wheels and the latter may also be adjusted, thus enabling us to secure the running of the shovels at any desired depth. The construction is also simple and can be easily adjusted, as

described, by the operator in a Jfew moments,

not requiring the services of a skilled mechanic.

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