THILL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 727,604, dated May 12, 1903.

Application fded October 17. 1902. Serial No. 1277.732. (No model.)

To rtZ whom t muy concern:

Be it known that I, GEORGE SAvLoR ENG- LER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented aV new and useful Pole and Thill Coupling, of which the following is a specification.

The invention relates to couplings for poles and thills.

The object of the present invention is to improve the construction of couplings for poles and thills and to provide a simple, inexpensive, and efficient one of great strength and durability, adapted to be readily applied to a vehicle and capable of enabling the wear of the parts to be readily taken up to prevent rattling without bending, straining, or otherwise injuring the parts of the coupling.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective View of a coupling constructed in accordance with this invention. Fig. 2 is a plan view, partly in section. Fig. 3 is a detail perspective View of the adjustable rod or pivot.

Like numerals of reference designate corresponding parts in all the iigures of the drawings.

1 designates a clip-plate designed to be secured to an axle by an ordinary axle-clip and provided with a frame having forwardly-extending sides or ears 2and3 and a connecting transversely-disposed rear portion 4, which is formed integral with the clip-plate; but the forwardly-extending sides or ears may be connected with an axle in any other desired manner. The sides or ears 2 and 3 are provided with openings 4 and 5 for the reception of a rod or pivot, which is adjustable transversely of the coupling, as hereinafter explained, and which is provided with means for rmly engaging the sides or ears in any of its adjustments. The ends 6 and 7 of the rod or pivot are threaded :for the reception of nuts 8 and i) for engaging the outer faces of the sides or ears, and the said rod or pivot is provided adjacent to the threaded end 7 with polygonal portions 10 and ll, preferably squared, as shown; but they may be of any other desired configuration. The opening 4. of the side 2 is round to receive the round portion of the rod or pivot, and the other side 3 is provided with a polygonal opening to conform to the conguration of the outer polygonal portion 11, which is larger than the inner polygonal port-ion 10. The round intermediate portion of the pivot or rod receives an eye l2 of a thill or coupling-iron 13, which is designed to be connected with a thill ora pole in the ordinary manner, and the inner end of the eye is engaged by a detachable collar or head 14., which is arranged on the inner polygonal portion l0. The detachable collar or head 14 is also engaged by the inner end 0f the outer polygonal portion, which forms ashoulder for this purpose. The inner side of the collar or head, which is fixed to the rod or pivot, bears against the inner end of the eye 12, and when the parts become worn through use the nut 9 is loosened and the other nut is rotated to draw the detachable collar or head 14. tightly against the eye, which is firmly held between the same and the side 2 by the frame. The outer polygonal portion prevents the pivot or rod from rotating, so that there is no liability of the nuts accidentally nnscrewing, and the said outer polygonal portion is adapted to slide in the opening of the side 3 to permit this adjustment, which is effected without drawing the sides 2 and 3 together and without bending, weakening, or otherwise injuring the same. After the parts have been adjusted in this manner the nut 9 is again screwed tightly against the side 3.

It will be seen that the device is exceedingly simple and inexpensive in construction, that it possesses great strength and durability, and that it is capable of ready adjustment to take up the wear and to prevent noise andrattling. It will also be apparent that the adjustment of the pivot-bolt does not bend or otherwise injure the sides or ears and that the nuts iirlnly engage the sides of the frame after the adjustment has been effected.

What is claimed isl. In a device of the class described the combination with forwardly-extending perforated ears, one of the ears being provided with a polygonal opening, a pivot or rod arranged in the openings of the ears `and provided with threaded ends and having inner and outer po- Ico lygonalportions adjacent to one end,the outer polygonal portion being of greater diameter than the inner one and fitting the polygonal opening of the adjacent ear, a detachable collar or head arranged on the inner polygonal portion and arranged to engage the eye of a couplingiron, and nuts arranged on the threaded ends of the pivot or rod and engaging the outer faces of the ears, substantially as described.

2. In a device of the class described the combination of a clip-plate having a frame provided With forwardly-extending sides o1' ears having openings, one of the openings being polygonal, a pivot or rod passing through the openings and having threaded ends and provided adjacent to one end With inner and outer threaded ends of the rod or pivot and engagy ing the sides of the frame, substantially as described.

In testimony that I claim the foregoing as my oWn I have hereto afxed my signature in the presence ot' two Witnesses.
