CULTlVATOR-COUPLING.

SPECIFICATION forming part of Letters Patent N0. 752,594, dated February 16, 1904.

Application filed September 3, 1903. Serial No. 171,748. (No model.)

To all whom it may concern.-

Be it known that LANDREW V. RYDER,a citizen of the United States, residing at Bellevue, in the county of Huron and State of Ohio, have invented certain new and useful Improvements in Cultivator-Couplings; and I do 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.

My invention is an improved coupling for coupling the draw-bar of a cultivator-beam to the transverse supporting-barof the cultivator-frame and to admit of the cultivator-beam being adjusted both laterally and vertically; and my invention consists'in the construction, arrangement, and combination of devices hereinafter described and claimed. 7

In the accompanying drawings, Figure 1 is a perspective view of a portion of a sulkycultivator provided with my improved coupling. Fig. 2 is a detailperspective view of my improved cultivator-coupling. Fig. 3 is a horizontal sectional view of the same, taken on the plane indicated by the line a a of Fig. 2. Fig. i is a vertical sectional view of the same, iaken on the plane indicated by the line b b of In Fig. 1 of the drawings, which illustrates a portion of a sulky-cultivator of ordinary construction, the transversely-disposed supporting-bar, to which the draft-rods of the cultivator-beams are connected, is indicated at 1, the cultivator-beams areindicated at 2, and their respective draw-bars are indicated at 3 and have their front portions upturned vertically, as at 4.

My improved couplings are adapted for connecting the said upturned front ends of the draw-bars to the supporting-bar, so that the cultivator-beams are adaptedto be laterally adjusted on the supporting-bar to widen or narrow the space between the cultivator-beams,

according to the width of the spaces between the rows of corn, and the said couplings are also adapted to permit of the vertical adjustment of the draft-bars and cultivator-beams to regulate the depth to which the cultivator shovels or points penetrate the earth when in operation. I I will now describe one of my said improved cultivator-couplings, which is shown in detail in Figs. 2, 3, and 1 of the drawings.

The body 5 of the coupling, which in practice is preferably a malleable casting, is provided on one side with a pair of cylindrical sleeves 6, whichare horizontally disposed in line with each other and the inner ends of which are suitably spaced apart, as at 7. These sleeves are split on their rear sides from end to end, as at 8, and are provided at their inner ends with rearwardly-extending lugs 9. A pair of lugs is thus provided for each of the said cylindrical split sleeves, and the said pairs of lugs are connected together by clamping-bolts 10. The cross-bar or supportingbar of the cultivator passes through the said sleeve 6 and the coupling is adjustable longitudinally on the said cross or supporting bar and is hence adjustable laterally with respect to the cultivator-frame and to the next adja- ]cent coupling on the said supporting or cross To secure the coupling at any desired adjustment on the cross-bar, I provide a split collar 11, which is also disposed on the crossbar and in the space 7 between the inner ends of the said sleeves and is provided at its projecting ends with a clamping-bolt by means of which it may be securelyclamped. It will be understood that the bolts 10, with which the sleeves 6 are provided, enable thesaid sleeves to be contracted readily from time to time, as may be required, to take up the wear on the cross-bar. It will also be understood that the said sleeves effect apivotal connection between the coupling and the cultivator cross-bar, so that the coupling is movable angularly in a vertical plane thereon.

On the front side and at the center of the body 5 of my improved coupling are formed a pair of vertically-disposed cylindrical split sleeves 13, which are perpendicular to the sleeves 6 and are similar in construction there to. The lugs 14 of the sleeves 13 are connected together in pairs by clamping-bolts 15, and the inner ends of the said sleeves are appropriately spaced apart, as at 16. The vertical portion of the cultivator-beam'draw-bar extends through the vertically-disposed split sleeves 13 and is vertically adjustable therein. The bolts 15, in connection with the peculiar construction of the split sleeves 13, enable the latter to be compressed readily, as may be required, to take up the wear of the said drawbar, and the latter is maintained at any required vertical adjustment in the'coupling by means of a split collar 17, which is similar in construction to the collar 11, hereinbefore de scribed, is clamped on the vertical portion of the draw-bar by the bolt 18, and is disposed in the space 16 between the inner ends of said split sleeves 13.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

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

1. A cultivator-coupling of the class described, having a pair of horizontally-disposed clamping-sleeves to engage the cross-bar of a cultivator and having a pair of perpendicularly-disposed clamping-sleeves to engage the vertical portion of a cultivator-beam draw-bar.

2. A cultivator-coupling of the class described, havinga pair of horizontally-disposed split clamping sleeves to engage the cross-bar of a cultivator, a pair of perpendicularly-disposed split clamping-sleeves to engage the perpendicular portion of the cultivator beam draw-bar, and means to contract said clamping-sleeves on said cross-bar and cultivatorbeam draw-bar.

3. A coupling of the class described, having a pair of sleeves spaced apart and adapted to engage and slide upon an element of a cultivator, and a clamping-collar on said element of the cultivator and disposed in the space between said sleeves to secure the coupling when adjusted on said cultivator element.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
