CLEVIS.

Application filed January 17, 1916.

To all whom it may concern:

Be it known that I, GEORGE H. METGALF, a citizen of the United States, residing at lVilkinson, in the county of Wilkinson and State of Mississippi, have invented new and useful Improvements in Clevises, of which the following is a specification.

The present invention relates to clevises for plows and similar farming implements.

An object of the invention is to provide a clevis of simple and improved construction which will permit of a vertical adjustment of the draft without removing any of the parts constituting the clevis when the same is applied to the plow beam.

A further object of the invention is to produce a clevis of the character described which will permit of not only a vertical adjustment of the draft, but further retain the draft in its respective adjusted positions.

With the above and other objects in view, the invention consists of the novel features, details of construction, and combination of parts which hereinafter will be more fully illustrated in the accompanying drawing and pointed out in the appended claims.-

In the accompanying drawing :Figure l is a side elevation partly in section showing the front end of a plow beam equipped with my improved clevis; and Fig. 2 is a perspective view showing the position occupied by the parts when the draft link is to be ad justed.

Referring more specifically to the drawing wherein like reference characters refer to corresponding parts in the several views the improved clevis includes in its construction a bracket 5 of U-shaped configuration embodying an upper limb 6 and a lower limb 7, the limbs being connected with one another through the medium of a connecting portion 8. The top and bottom limbs may be described as consisting of bars fitted upon the respective upper and lower faces of the plow beam B and stationarily mounted on the forward end thereof through the medium of pins or bolts 9. The connecting portion 8 being also in the nature of a bar is disposed forwardly of and vertically of the extreme forward end of the plow beam B when the clevis is in applied position as shown. This connecting portion gradually increases in transverse width from the upper limb 6 toward the lower limb 7, by dis- Specification of Letters Patent.

posing the outer vertical edge 10 thereof in a downward and forward inclined direction, the purpose of which is to enable the insertion of the draft link 11 within the U-shaped recess 12. The U-shaped recess 12 is constructed by disposing in vertical opposed relation with the connecting portion 8 and forwardly thereof an L-shaped draft stand ard 13, said standard being integrally connected with the bracket 5 by means of the horizontal portion of the draft standard 14. This draft standard 13 has formed on its innermost surface a series of notches 15 which are arranged in vertical superposed relation one to the other and continued around on the side faces 16 of the standard, as indicated by the character 17, whereby the draft link will be permanently held against any slight vertical movement when the same is connected with the clevis.

The entrance to the U-shaped recess 12 is obstructed by a plate 18 and is permanently connected in obstructing relation with respect to the recess 12 through the medium of a pair of screws 19 and 19, the screw 19 engaging the upper end of the connecting portion 8 while the screw 19 being screwed into the upper free end of the draft standard 13. This plate has formed on the under surface thereof at a point substantially medially of its length a keeper 20 in the nature of a stout flat flexible spring bowed in a direction toward the notches 15 of the draft standard 13 and the office of which is to retain the draft link in its proper vertical adjusted position and prevent any accidental displacement of the draft link from the draft standard 13. A further object of the keeper 20 more especially owing to its resilient nature, is to permit of the removal of the draftlink 11 from one of the notches of the draft standard and the insertion in a further notch thereof without the necessity of removing the plate 18.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of construction and of the method of operation will be readily apparent to those skilled in the art to which the invention relates, and while I have described the principles of operation of the device together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such advantages may be made when desired as are within the scope of the appended claims.

I claim:

1. A device of the class described embodying a U-shaped bracket comprising a vertically disposed connecting portion, an L-shaped draft standard formed contiguous with and disposed forwardly of the connecting portion of the bracket and defining a substantially U-shaped recess, a draft link mounted in said recess, a plate closing said recess and a keeper formed integral with the plate and preventing the displacement of the link from said standard.

2. A device of the class described embodying a U-shaped bracket consisting of a vertically disposed connecting portion, an

L-shaped draft standard formed contiguous v with and disposed forwardly of the connecting portion of said bracket and having a series of vertically alined notches, the positioning of the draft standard with respect to the bracket defining a U-shaped recess, a draft link positioned in said U-shaped recess, a plate closin r ent bowed keeper formed integral with the plate and depending withinthe recess for holding the draft link in the notches of the standard and permitting of a vertical adjustment of the link with respect to said standard.

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