CLEVIS.

SPECIFICATION forming part of Letters Patent No. 513,854, dated January 30, 1894.

Application filed October 7, 1 8 93 To all whom it may concern: I

Be itknown that I, AARONMATTHIASWORD, a citizen of the United States, residing at Amar1lla, in the county of Potter and State of Texas, have invented a new and useful Olevis, of which the following is a specification.

My invention relates to improvementsin clevises; and the objects in view are to prov1de a clevis of cheap and simple construction; that may be readily manufactured and applied to anyordinary draft-beam, and which 1s so shaped or formed as to adapt it to obviate the necessity of using the usual lapring for connecting the same with the singletree; and, furthermore, to adapt it for use in connection with a single-tree whose staple or eye 1s disposed in aplane with the said singletree.

Other obj ectsand advantages of the invention will appear in the following description and the novel features thereof will be particularly pointed outin the claims.

Referring to the drawings:Figure 1 is a perspective view of one end of a draft beam provided with a olevis embodying my invention. Fig. 2 is a detail in perspective of the olevis. Fig. 3is a longitudinal sectional view of Fig. 1. Fig. 4 isa front elevation of Fig. 1.

Like numerals of reference indicate like parts in all the figures of the drawings.

In practicing my invention I preferably notch the front end of the beam 1 in a vertical manner as at 2, and in rear of said notch provide the beam with the usual bolt-hole 2 passing vertically therethrough for the accommodation of the bolt 4:. The olevis is formed of a blank of rod-iron, which is bent at its ends to form upper and lower eyes 5 and 6. The blank of iron at one side of its center is curved orbent upon itself to form avertically 0 disposed loop 7, and at its opposite side is curved or bent to form the horizontally disposed loop or eye 8. By reason of the formation of these loops and the bending of the rod I produce the upper and lower terminals 9 and 10, respectively, which merge 7 into the eyes 5 and 6, and between the loops 7 and 8 I produce the lug or nose 11 at the center of the olevis. Inasmuch as one loop is disposed in a vertical plane and the other in ahorizontal 5o plane, it will be obvious that the two loops are disposed at right angles to each other.

Serial No. 487,461. (No model.)

It is customary to provide singletrees with staples or eyes that are vertically disposed, and hence as the usual olevis is likewise vertically disposed it is necessary to employ an intermediate horizontally disposed lap-ring for coupling the staple of the singletree and the vertical loop of the clevis. It is obvious, however, that if the olevis-loop were horizontally disposed the lap-ring might be omitted and would no longer be necessary, and it is for this reason that I form the horizontal loop 8, namely, so that it may be connected with the ordinary singletree loop without the interposition of the usual lap-ring. It may be, however, desired to provide the singletree with a horizontally disposed eye, in which case it would be necessary to employ the lap-ring if the same were connected to thehorizontally disposed olevis-loop. To meet this contingency, however, I provide the upper vertically disposed'loop 7, and hence it will be seen that the two may be connected without the interposition of the usual lap-ring.

The manner of connecting the singletree with the olevis is the same as usual, namely, by a removal of the olevis from the end of the draft-beam, which may be accomplished by first removing the bolt 4 and inserting one of the terminals through the eye of said singletree. Of course by inserting the upper terminal through the eye, the singletree will be connected with the upper loop 7 of the olevis, and by inserting thelower terminal 10 through the eye of the singletree, the latter will be connected to the lower loop 8 of the olevis, all as will be obvious. The rearward bend forming the nose 11 engages with the vertical groove in the end of the draft-beam, and the olevis is thereby locked against lateral swingingand maintained directly in the line of draft.

From the foregoing description in connection with the accompanying drawings it will be seen that I have provided a very simple, easily applied and cheaply constructed olevis, and that the same is designed to obviate the use of the usual lap-ring.

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

Having described my invention, what I claim is-- 1. The herein described clevis, formed of a single piece of metal, the same adapted at its ends to connect with a draft-beam and between its ends at its front bent to form the two forwardlydisposed loops or eyes, arranged one above the other and at right-angles to each other.

2. The herein described improved clevis, the same formed of a single piece of metal and comprising the opposite terminals 9 and 10 terminating in the eyes 5 and 6, andsaid terminals at their front ends being bent to form a vertical loop 7 and a horizontal loop 8, substantially as specified.

3. The combination with the plow-beam having the front vertically grooved end, and

in rear of the same provided with a hole, of the clevis comprising the upper and lower terminals 9 and 10 embracing the beam, terminating at their rear ends in eyes 5 and G, and at their front portions bent to form the vertical loop 7, the horizontal loop 8, and the intermediate inwardly disposed nose 11 engaging the groove, and the bolt 4 passed through the eyes 5 and 6 and the hole in the beam, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature 1n the presence of two witnesses.
