DRAFT-EQUALIZER.

.SPECIFICATION forming part of Letters Patent No. 364,487, dated June 7, 1887.

Application filed March 4, 18877. Serial No. $229,718. (No model.)

To aZZ whom it may concern,.-

Be it known that I, JOHN DAILEY, a citizen of the United States, residing at Van Wert, in the county of Van Vert and State of Ohio,

have invented a new and useful Improvement in Olevises, of which the following is a speciiication.

My invention relates to clev-ises for attaching singletrees to doubletrees and for other purposes, and aims to provide a device whereby the draft upon the animals may be equaliZcd without employingy` any of the cumbersome forms of whiffietrees technically known as draft-equalizers. This object I attain by i5 the use ofthe device shown in the accompanying drawings; and thc novelty consists in ce1'- tain features thereof, hereinafter fully described, and particularlypointed out in the claims.

In the drawings, Figure l is a perspective -view of the end ofthe doubletreeprovided with myimproved clevis. Fig. 2 is aside elevation of the clevis, and Fig. 3 is a central longitudinal section of the same.

Referring to the drawings by letter, A designates the doubletree, and B re-enforcing metallic strips or bauds secured to the opposite sides or edges of the same. bands B are provided with aseries of corrugations, O, the purpose of which will be hereinafter fully set forth.

The clevis consists of the coupling-link D and the stirrups E and suitable connecting and fastening devices, all of which I will `now 3 5 proceed to describe. The coupling-link D encircles the end of the whi'filetree and extends a short distance forward of the same, as shown, in order to receive the ring secured to the rear side of the singletree. The front end of the 4o coupling-link D is also made semicircular in order to more easily and perfectly engage the said ring aforesaid. The rear end of the coupling-link is formed by a cross-bar, d, the rear side of which is flat and smooth, and the front side of which is provided with a longitudinal i rib, d', which engages the corrugations C of the band on the rear side of the doubletree.

F designates longitudinal slots in the sides of the coupling-link, near its forward end, and

These strips or` G is a socket formed in the rear side of the 5o cross-bar d, and which will be presently more fully referred to. l

The stirrup E is a U -shaped metallic bar so arranged that the shoulder of the U is in rear of and abuts against the cross-bar d of the 5 5 coupling-link, while the arms of the U extend forward alongside the sides of the couplinglink. The ends of the stirrup E are provided with perforations e, through which and the slots F, I pass a bolt, pin, or similar device, 6o H,which engages the corrugationsin the band on the front side of the doubletree. I is an adjusting and securin g bolt or screw which passes th rough a screw-threaded opening in the shoulder of the stirrup and engages or enters the y socket G in the cross bar d of the couplinglink. The end. of this screw or bolt I is not screw-threaded, and consequently acts or rests in the socket G, as in a journal -box, so that when it is turned, instead of `going through the 7o said cross-bar, it will push thesame forward into'engagement with the corrugations C, hereinbefore mentioned.

The rear lower corner of the shoulder of the stirrup is bent ont of the straight line of the main portion of the same to form the groove or loop J to receive and hold. the cockeye K, to which is secured one end of the chain which extends from the doubletree to the axle of the vehicle.

Having thus described the construction and arrangement of the several parts of my device, its operation is as follows: The coupling-link and stirrup are placed in proper position and K the securing-screw inserted through the ends S of the same, as described. The several parts are then placed at a point on the whiflletrec where the crossbar d and bolt H will engage the corrngations when the bolt I is operated. The said bolt I is then turned so as to cause 9o the said cross-bar and bolt to engage and bind against the corrngations, as will be understood.

It will be seen that my device can be quickly and easily applied to the doubletree, and consists of very few parts, and those few of simple f construction. By securing the device to the doubletree at a greater or less distance from the tongue of the vehicle the leverage will be increased or diminished, and in this way the draft upon the animals may be equalized ac cording to their strength.

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

1. The combination, with the doubletree, of the coupling-link encircling the same, the stirrup embracing the coupling-link, and mechanism whereby the stirrup and coupling-link are made to mutually bind against the opposite sides or edges ofthe doubletree, as set forth.

2. The combination, with a doubletree having a series of corrugations on its opposite sides, near its end, of the clevis having means for engaging the corrugations and binding Within the same, substantially as set forth.

3. `The combi11ation,with the doubletree, of the coupling -linl having one end bearing against the whifietree and having slots in its sides, near its 'opposite ends, the stirrup embracing the coupling-link and carrying a bolt, pin, or similar device which passes through the slots in the sides of the coupling-link, and a screwr or bolt passed through the shoulder ofthe stirrup and journaled in the end of the coupling-link, substantially as specified.

4. rlhe combination, with the doubletree, of the coupling-link adj ustably secured thereto, and the stirrup connected with the couplinglink and carrying the cockeye, as and for the purposes specilied.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two Witnesses.'

Jenn BAILEY.
