THILL-COUPLING.

SPECIFICATION forming part of Letters Patent N0. 624,602, dated May 9, 1899.

Application iiled .Tuly 29, 1898.

To ajZZ whom tmc/y concern.-

Be it known that I, CHARLES WV. YOUNGS, a citizen of the United States, residing' at Willis, in the county of VVashtenaw and State of Michigan, have invented a new and useful Thill-Ooupling, of which the following is a' specification.

The invention relates to improvements in thill-couplings.

The object of the present invention is to improve the construction of thill-couplings and to provide a simple, inexpensive, and efficient device adapted to be readily applied to an ordinary thill-coupling and thill-iron without necessitating any alteration in the construction thereof and capable of dispensing with a nut or similar fastening device.

A further object of the invention is to provide a thill-coupling which will enable a pair of thills or a pole to be readily attached to and removed from a vehicle and which will form an effective antirattler.

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

In the drawings, Figure l is a perspective view of a thill-coupling constructed in accordance with this invention. Fig. 2 is a transverse sectional view. Fig. 3 is a detail perspective View of the pivot and the lockingspring.

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

1 designates an axle-clip provided with forwardly-projecting ears 2, having perforations adapted to register with an eye 3 of the thilliron 1i and receiving a transverse pivot 5, which passes through the eye of the thill-iron and couples the same to the aXle-clip. One end of the clip is provided with a vertical arm 6, located at one side of .the thill-coupling at the outer face of theadjacent ear and extending above and below the same. The upper end of the arm 6A is bifurcated and receives an eye 7 of an L-shaped spring S. .The eye is hinged in the bifurcation by a suitable pintle 9, and the L-shaped spring extends' across the top of the coupling and down the Serial No. 687,226. (No model.)

opposite side thereof and engages the adja cent end of the pivot to -lock the latter in p0 sition. The pivot projects beyond the axleclip, and the depending or vertical iside or arm of the L-shaped locking-spring is' provided with an opening to receive the projecting end of the pivot. The arm, which is provided with the opening, is adapted to be readily disengaged from and engaged with the 6o pivot without the use of a wrench or analogous tool, and by this construction a pair of thills or'a pole may be readily coupled to and uncoupled from a wagon, cutter, or analogous vehicle.

Within the locking-spring is arranged a Vtransverse cushion l1, consisting of an oblong block or strip of rubber secured to the inner face of the top arm of the locking-spring and bearing against the top of the eye of the thill- 7o iron. This cushion effectually prevents the thill-iron from rattling, and the lower end of the ar1n-6 is provided with an inwardly-ex-V tending lip 12, arranged beneath the lower edge of the adjacent ear of the axle-clip and bearing against the same,whereby the pivot is' prevented from turning in the eye of the thill-iron and the perforations of the ears. The lip l2 effectually prevents the device which connects the parts from rattling.

The invention has the following advantages: The thill-coupling, whichissimplc and comparatively inexpensive in construction, dispenses with a nut, and it may be readily operated without the use of a wrench lor similar tool, and it will enable a pair of thills or poles to be readily changed from one vehicle to another. The inwardly-extending lip of the arm of the transverse pivot enga-ges one of the perforated ears and prevents the coup- 9oV ling from rattling.

What is claimed isy In a device of the class described, the combination with an axle-clip having perforated ears, and an iron having an eye arranged between the ears, of a pivot passing through the eye and the perforations ofthe ears and having one end extended beyond one of the'latter, the arm rigid with the other endl of the pivot and extending above and below the ico same and provided at its lower end with an inwardly-extending lip engaging the lower edge of the adjacent ear to look the pivot my own I have hereto affixed my signature in against rotation and to prevent the parts from the presence of tWo Witnesses. rattling, and a looking-spring hinged to the upper end of the arm and engaging the ex- 5 tended end of the pivot and provided with a Witnesses:

cushion, substantially as described. LEE N. BROWN,

In testimony that I claim the foregoing as AVERY VVHITAKER.
