1b @ZZ whom it may concern: n l

Be it known that I, WILLIAM F. SCHUBERT, a citizen of the United States, and a resident of Oneida, in thecounty of Madison, in the State of New York, have invented new and.,

nsefullmprovernents in'flhill-Couplings, of which the following, taken in connection with the accompanying-drawings, is a full, clear, and exact description. 7

This invention relatesto the-class of thill- Thevv object of my'present invention is to securely fasten the actuatingfspring of the coupling to theantirattler-j aw by simple and convenient means and at the vsame time reinforce said'spring andv protect itvf rom wear and abrasion at its'fulcrum and to that end the invention consists, essentially, in the combination, with the. shackle-ears of the axle, shackle-eye of the thill-iron, the coupling-pin formed with'a downward extension, vand the antirattler-jaw pivoted to said extension, Of a shoe formed on the back of said jaw in position to contact with the fulcrum of the jaw and the actuating-spring passingthrough said shoe and fastenedthereby to the jaw; and the invention consists also in novel features of the detail construct-ion of parts of the thill-coupling, as hereinafter described.

In the' accompanying drawings, Figure l is av vertical longitudinal section of a thill-conpling embodying my improvements. Fig. 2 is a transverse section on line X X in Fig. l. Fig. 3 is a detached perspective View of the antirattler-jaw and wear-plate, and Fig. 4 is a transverse section on line Y Y.

Similar letters of reference indicate corresponding parts.

a represents one of the pair of shackle-ears which project from the usual clip C, which embraces the axle A and bed-piece A and is fastened thereto by the clip-tie C and nuts n n on the ends of the clip in the usual and well-known manner.

eye c, so as tomaintain the same in constant v contact with the coupling-pin d.'

h represents the actuating-spring by meansof which the antirattler-jaw g receives the aforesaid pressure. Said spring extends rearward u nder the axle and has connectedto its rear end a lever c', which [is fulcrurned on a link Z, suspended from a suitable support on the clip-bar C', vpreferably from the rear of said clip-bar, which is provided with a sho,ul=

vder t back of the link to prevent the latter from accidentally slipping O from the clip= v bar.

*The antirattler-.jaw g is formed with a sleeve g', which extends across the jaw and embraces the parallel bar f and is thus pivoted -directly to said bar.

The spring h is fastened to the jaw g by means of a shoe s, formed on said jaw and receiving the spring through it and securely gripping the spring by compression of the shoe, thus fastening the spring to the jaw without the use'of rivets, which in perforating the spring tend to weaken the same.

The shoe s is formed on the back of the antirattler-jaw g by a plate u, extending across the spring and formed integral with the said jaw at one side thereof, the remaining portion of said plate being free to allow it to be compressed toward the jaw, so as to firmly grip the spring in the shoe, as aforesaid.

The plate u, while stiffening the portion of the spring bearing on the jaw g, at the same time serves as a wear-plate which is disposed to contact with the clip-bar C', on which the jaw g is fulcrumed. The interposition of the said wear-plate between the spring and aforesaid fulcrum protects the spring from wear and abrasion, which the spring would be sub- IOO j eoted to if allowed to Contact with the clip tie or fulorum.

What I claim as my invention isl. In combination with the shackle-ears of the axle, .shackle-eye of the thill-iron, the coupling-pin formed with a downward extension, and the antirattler-jaw pivoted to said extension, a shoe formed on said jaw, and the actuating-spring passing through said shoe and fastened thereby to the jaw as set forth.

2. In combination with the shackle-ears of the axle, shackle-eye of the thill-iron, the coupling-pin formed with a downward extension, and the antirattler-jaw pivoted to said extension, a shoe formed on the back of said jaw in position to Contact with the fulcrum of the jaw, and the actuating-spring passing
