THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 628,852, dated July 1 1, 1899. Application filed. May 1, 1899. Serial No. 715,162. KNO model.)

To all whom it may concern:

Be it known that I, FREDERICK Runen, a citizen of the United States, residing at Eutaw, in the county of Greene and State of Alabama, have invented a new and useful 'lhill- Coupling, of which the following isa specification.

This invention relates to thill-couplings, and has for its object to provide simple and improved means for preventing longitudinal displacement of the thill-bolt and rattling thereof.

To this end the present invention consists in the construction and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of the improved thill-coupling. Fig. 2 is a transverse sectional view taken through the thill-bolt. Fig. 3 is a longitudinal sectional view on the line c x, Fig. 2. Fig. e is a detail perspective view of the antirattlerspring and bolt-lock.

Corresponding parts are designated by like reference characters in all the figures of the drawings. f

Referring to the accompanying drawings, l designates an ordinary axle-clip having the usual spaced bearing-ears 2 and the tie-bar 3, whereby the clip may be fastened upon an axle et. The thill-iron 5 is provided with an eye 6, which is adapted to be located between the ears 2 and connected thereto by means of a smooth bolt 7, passing loosely through the eye and the opposite bearing-ears. One end of the bolt is provided with ahead S, adapted side ll of the spring is provided with suitable bolt-openings 12, adapted to receive the opposite ends of the axle-clip, whereby'the said side 11 may be clamped against the under side of the axle by means ofthe tie-bar 3. The .upper free end of the side 1l is extended longitudinallyoutward beneath and beyond the `bearing-ears'2 and then bent back upon itself, forming the antirattler-spring tongue 13, having its free extremity flared slightly upward, located between the bearing-ears and adapted to bear upwardly against the thill-eye t3. The lower side of the U-shaped spring is also extended forward beyond the bearing-ears and bent backward upon itself, as at 14, and the free extremity of the bend is provided with an offset upstanding arm 15, adapted to engage the outer face of one of the bearing-ears 2. This arm is provided at its Lipper end with a longitudinal slot 16, opening outward through the upper end of the arm and inclined upwardly and rearwardly toward the axle. As indicated in Figs. 1 and 3, the arm l5 is adapted to receive the grooved or reduced portion 9 of the thill-bolt within the slot 16,

so that the outer shoulder 17 of the bolt may engage the opposite sides of the slot. and thereby prevent the bolt from being displaced longitudinally from the thill-eye and the bearing-ears 2. It will be understood that the arm 15 is effectually held in engagement with the reduced portion of the thill-bolt by means of the lower side or member of the U -shaped spring 10, and the slot is inclined rearwardly for the purpose of facilitating the engagement of the slotted arm with the thill-bolt.

It will be noted that the construction, as hereinbefore described, provides an antirattler-spring and a locking-arm for the thillbolt, all formed from a single piece of metal, which is positively connected to the axle-clip, so as to prevent possible loss of either of the parts.

The present invention may be readily applied to any of the common forms of thillcouplings without altering any part thereof,

and by the employment of the device the thill-bolt is etectually locked against accidental displacement and rattling of the thill arm or bolt within the bearing-ears is effectually prevented. Also,the antirattler-spring tongue 13 and the upstandin'g arm 15 aregentirely independent of each other, being carried by the lindividual ends of the U-shaped IOO spring 10, so that the arm lo may be disengaged from the bolt 7 without moving or otherwise interfering with the antirajttlerspring.

Changes in the form, proportion, size, and the minor details of construction Within the scope of the appended claims may be resorted to Withoutdeparting from the spirit or sacriiicingany of the advantages of this invention.

WVhat I claim is- A l. In athill-conpling, the combination with an axle-clip having opposite l'iearing-ears, a thill-iron, and a thill-bolt, of a substantially U-shaped springlhaving its upper side connected to the ends ot' the clip7 the forward free end of said Side being rebent across its upper face and forming an antirattle'r-spring tongue engaging the thill-iron, and the lower side of the U-shaped spring having its forward free end rebent into a spring-tongue, the latter having a laterally-offset'upstanding arm engaging the thill-bolt, substantially as and for the purpose set forth.

2. In a thill-eonpling7 the combination of an axle-clip having opposite bearing-ears, av thill-iron, a thill-bolt having a head at one end and a reduced portion provided near the opposite end of the bolt, and a substantially U-shaped spring formed from a at strap of metal bent intermediate its ends, one of the sides of the spring being provided with boltopenings, whereby the spring may be secured to the ends of the clip and the free end of said FREDERICK REEsE.
