THILDCOUPLING.

SPECIFICATION forming part of Reissned Letters Patent No. 11,260, dated August 1 6, 1892; original lurkfiml'h'l, dated-July 14,-189L Application for reissue filed September 2. 1891- Serial No. 404,565

ToalL whom it may concern.-

.Be it known that I, WILLIAM HENRY HAN;

- NAN, of Syracuse, in the county of Onondaga,

in the Stateof New York, have invented new and useful Improvements in 'lhill-Couplings,

. United. States Letters- Patent No. 341,235,

- operation and capable of compensating for dated May 4; 1886.

The object of my present-invention is to provide the thill-couplingwith a locking device which shall be more secure and. reliable in its the weal-and abrasion of the coupling pin and draftey'e; and to that end the invention consists in the improved construction and combination of parts, as, hereinafter more fully described, an d set forth in the claims.

In the annexed drawings, Figure l is a side view of a thill-couplingembodying my improvements. Fig. 2 is atop plan'view of the same.

. of the draft-eye in its open position, and Fig. 5 is an inverted plan'view ofthe clip-tie.

, Similar letters of reference indicate correspending parts.

A represents the-front axle of a vehicle. To the under side of said axle, near eachjend thereof,is applied a clip-tie C, which is elongated in the direction lengthwise of the axle 1 known nianner. g

center of its length with the forwardlywx- -lip L.

and is doubly secured thereto by two clips'C- C, embracing the axle and fastened to the two ends of the clip-tie in the usual and well- This clip-tie is formed at the .t represents the thill-iron, which has either rigidly attached to or formed integral with it the coupling-pin projecting laterally from the i thill-iron, as indicated by dotted lines in Fig. 2 or the drawings, and terminated with a head t. Between the central portion-of the cliptle O and under side of the axle A is clamped Fig. 3 is a vertical longitudinal sec'' tion on line a: m, Fig. 2. Fig. 4 is a side view one end of aspring-arm 0, and preferably secured in .position by a spur s on top of the .clip-tie entering a recess iin'the'uuder side of the spring-arms, as shown in Fig. 3 of the drawings, said spring-arm extending from the rear of the clip=tie and thence forward underneath the same and has hinged to its free end a cam-lever d, which inoves ina vertical plane.

'To this cam-leveigat a point eccentric to the hinge thereof, is connected 2:. suitable tie, pref- 'erably of the form of a bail e, which embraces the rear portionsv of the draft-eye sections 1) b and is adapted to lie with its top cross-bar on the lip Z of the hinged eye-section b, as,

illustrated in Figs. 1 and 2 of the drawings.

When the thill is detached from'the vehi-' cle, the cam-lever d is swung forward and the hinged eye-section b, which is thus released from the tie or ball e,is swung forward, as represented in Fig. st of the drawings. To couple the thill to the vehicle, the couplingpin of the thill-iron is laid in the fixed drafteye section b. Then the hinged eye-section is swung back upon the coupling-pin,-the bail e placed upon the lip l, and then by drawing or pushing the free end of the cam-leverrearward it is caused to draw down the bail e,

which by its bearing upon the lip l presses the hinged eye-section b tightlyupon the coupling-pin with theforce exerted 'by the spring-arm a. After the cam-lever is carried past the center ofits movement it automatically springs rearward by the force of the spring-arm, and thus becomes sufficiently lockedto prevent its accidental displacement.

The constant pressure of the spring-arm effectually prevents the rattling of the thillcoupling and automatically compensates for draft-eye.

--Ha.-ving described my invention, what I .claiiu as new, and desi e to secure-by Letters Patent, is-' -1. .'lhe.- e;ombination, with the draft-eye comfree at the other, a cam-lever pivoted to the free endof said spring-arm, and? tie attached to the cam le'ver outside of its fulcrum and. connecting the cam-lever with the movable section of the draft-eye, whereby the springthe wear and abrasion of the coupling-pin and -9 posed of fixed section and a movable section, of a spring-arm securedat one end and the cam-lever d, hinged to the free end of said- 7 arm exerts a constant pressure upon the movable section and'alsoholds, the earn-lever yieldingly in a lockedposition, substantially as set forth. i

2. The combinationnrith the axle,ofadrafteye composed of a forwardly-projecting fixed section and a movable section hinged to the front end of the fixed section, a spring arm secured to the axle and projecting forwardly therefrom, a cam-lever hinged to the free ,frontend of the spring-arm, and a tie attached to the cam-lever outsideof its fulcrum and connecting the cam-lever with the hinged section. 0* the draft-eye, substantially as set forth. r i

In combination with the axle-clip, coupling-pin, fixed lower draft-eye section b, and the upper eye-section b, hinged tothe front of the fixed sectiomthe spring-arm c, secured at one end to the clip-tie and extending from the rear thereof forward underneath the same,

spring-arm, and the bail 6, connected to the cam-lever and adapted to'en gage. the rear end of the hinged eye-section, substantially as set 25 forth.

4. The combination, with the front axle and thill-iron, of the clip-tie G, elongated in the direction lengthwise of the axle and formed at the center of its length with the draft-eye section b, axle-clips C O, secured to the two end of said spring-arm, and thebail e, oonnected to said cam lever and adapted to bear on top of the rear end of the hinged draft-eye section, substantially as described and shown.

In testimony whereof I have hereunto signed my name this 26th day of August, 1891.

THEO. LIOPP, J ENNIE CLOUGH.
