THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 337,761, dated March 9, 1886.

Serial No. 176,877. (No n1o11- 1.)

To all whom it may concern:

Beit known that I, ALBERT FRENCH, acitizen of the United States, residing at East Rockport, in the county of Ouyahoga and State of 5 Ohio, have invented certain new and useful Improvements in Thill-Gouplings; and I do hereby declare that the following is a full,

' clear, and exact description of the invention,

which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to thill-couplings, the object being to provide a device of this character whereby all lateral movement of the thill-iron in the draw-iron and the consequent rattling are prevented.

A further object of the invention is to provide a thill-coupling possessing the abovementioned advantage which may be manu- 2 factored at a comparatively slight cost, one that will be strong and durable and not likely to get out of order.

My invention consists in the details of construction and combinations of parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a perspective View of a thill-coupling embodying my invention. Fig. 2 is alongitudinal vertical section of the same. Fig. 3 is a transverse verti- 0 cal section, and Fig. 4 is a detail view of the bushing removed.

Corresponding parts in the several figures are denoted by the same letters of reference.

Referring to the drawings, A represents a portion of the axle, secured to which is a clip, B, said clip having threaded ends. Fitting upon and connecting the ends of the clip is a bar or plate, O,and holding said plate in place are nuts a, which engage the threaded ends of the clip.

D represents the draw-iron, which projects outwardly from the clip, and is preferably formed integral therewith. This draw-iron consists of two outwardly-extending ears,

each of which is provided with an opening, I).

E represents the thill-iron,which is adapted to be bolted or otherwise firmly secured to the thill. This thi1liron E is formed with a head, (2, which has a transverse opening or passage.

\Vithin the opening or passage of the head d is formed a shoulder, j, which is preferably circumferential, and is located midway the ends of the head. This shoulder f may be formed by reaming out the head from opposite sides.

G represents a sectional bushing. which is preferably of elastic material, such as rubber or leather. The two parts or sections of the bushing G are passed through the openings in the ears of the draw-iron, and bear with their inner ends against the shoulderf, their outer ends resting in the openings of the ears of the draw-iron.

H represents aheaded bolt, which passes through the bushing or packing, and which is held in place to secure the parts together by a nut, g. The outer ends of the sections of the elastic bushing bear against the head of the bolt and the nut, and they serve as cushions for the same to prevent their wear and rattling. It will be observed that as the ends of the sectional bushing bear against the sides of the shoulder the lateral movement of the thill-iron is prevented, and as the bushing fits tightly in the openings forward and backward movement of the thill-iron is also prevented.

I am aware that it is not broadly new to provide the opening ofathill with asectional 8o bushing having its outer ends located in the opening of the draw-iron and forming a bearing for the pivotal bolt its entire length; but in constructions of this class, so far as I am acquainted, conical openings have been pro- 3 vided in the draw and thill irons, and a conical sectional bushing employed in combination with a bolt made conical for half its length. This construction of coupling has never been brought into general use,owing to its expensive construction, a special form of bolt being necessary,which,if lost,could only be replaced by the manufacturer. The bushings are not alike, one of them having a smooth interior bore, and the other a conical bore to fit the 5 conical portion of the bolt.

My construction differs from the construe tion before mentioned in that I make the openings of both the thill and draw irons plain,and provide a plain tubular bushing to fit in the thill-iron and have its ends'rest in the open- 'ings of the draw-iron and in combination with of said bushing bearing against opposite'sides of the shoulder f, and their outer ends bearing in the openings of the draw-iron, and the bolt A, corresponding to and passing through the opening in the bushing and a nut, sub stantially as set forth.

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