THILL-COUPLING.

SPECIFICATION forming' part of Letters Patent No. 632,550, dated September 5, 1899i Application filed February 27, 1899, serrano. 706,997. or@ more.)

" To @ZZ 'wiz/mn it may concern:

Be it known that I, GEORGE WILLIAM DA- VIs, of Granville, in the county of Washington and State of New York, have invented, a new and Improved Thill-Coupling, of which the following is a full, clear, and exact description. 4

The object of my invention is to so construct a thill-coupling that when the draftanimal is removed from the thills the thills will be automatically carried upward to a position of rest and held in such position.

Another object of the invention is to so construct a thill-couplin g that the thills or shafts may be quickly and conveniently disconnect-v ed from a Vehicle or applied thereto and when applied to the Vehicle will remainl in operative position under all conditions of travel and be practically noiseless while utilized for draft purposes.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fullyset forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure 1 is a vertical section through the axle of a vehicle and a side elevation of the improved thill-coupling, the thills shown in positive lines and partly in section being in the position to be entered upon the coupling, the dotted lines illustrating the position of the thill after having been entered upon the coupling. `Fig. 2 is a View similar to Fig. 1, illustrating indotted lines the position the thills will occupy after the animal has been disconnected therefrom, the position shown in positive lines being that which the thills will occupy when the Vdraft-animal is harnessed thereto. Fig. 8 is a plan View of a portion of the axle and theimproved coupling, the thills having been removed; and Fig. 4 is a detail rear elevation of the lower vend of a thill adapted for use in connection with the coupling.

A represents the front axle of a vehicle, and B the clip that is adapted to secure the improved coupling to the axle. The clip E is made to pass through a horizontal plate 10, forming a part of the body of the coupling,

which plate extends below the axle and b e-i yond the front and the rear thereof, and said plate is provided at each side of its forward end with an ear 11. I l

The movable portion of the coupling con= sists of a sleeve or barrel 12, located between the ears 11 of the body portion of the coupling and mounted to turn upon a screw or pin 13, passedthrough the barrel or sleeve 12 and through the ears 11, one end of said screw or pin being provided with a head and the other end with a nut 14 or the equivalent thereof.

projection, and from said nose 17 an arm 18` is rearwardly projected, said arm being more or less downwardly and rearwardly curved. The upper surface of the arm 1S isadapted to engage with a melnber of a bent spring 19, said spring being secured, preferably, between the axle A and body-plate 10 of the coupling, the lower end of the spring being curved in direction of one side of the running- I gear, extending transversely oven the upper surface of the arm 18, as shown in Figs. 1 and 2. Y

Each thill or shaft C is provided with a shoe D at its rear end, and an opening -20 is produced in said shoe, which opening at itslbottom 21 has a downward and rearward inclination.

When the improved couplings are employed and the thills or shafts are connected with the couplings, said thills or shafts are carried to the position shown in dotted lines in Fig. 1, the upper walls of the openings 20in the shoes of the thills or shafts entering the recesses 16 in the projection of the ,movable portions of said couplings. By pressing upward the arms 18 of the couplings, as shown in dotted lines in Fig. 1, the spring 19 is compressed, and the noses 17 of the couplings are brought in such position that the lower portion of the open- IOO ings 20 in the thills may becarried over the said noses, as shown in dotted lines in Fig. 1. The thills will thus be securelyfastened to the couplings, and when the vehicle is not in use the springs 19 by forcing downward the arms 18 will carry the thills to the position shown in dotted lines in Fig. 2 and hold the thills in such position, so that wherever the vehicle may be the thills will be held at an elevation from the ground or other support for said vehicle. 'When an animal is to be harnessed to the vehicle, the thills are drawn downward, assuming the position shown in positive lines in Fig. 2, wherein it will be observed that the thills are in firm engagement with the couplings and that the springs 19 are compressed, and it is evident also that under the improved construction of the coupling the thills when coupled thereto will not rattle or have undue wear while the vehicle is in use.

Having thus described my invention, I claimas new and desire to secure by Letters Patent* j 1. A thillcoupling, consisting of a bodysection adapted for attachment to an axle, a locking section pivotally attached to the body-section, said locking-section being provided with means for attachment to a thill and with an arm extending rearwardly beyond and beneath the body-section, and a spring attached, to a fixed support, which spring extends over the uppersurface ofthe projecting arm of the locking-section, as described. A

2. A thillcoupling, consisting of a bodysection provided with means for attachment to the running gear, and a locking-section pivotally attached to the body-section, said locking-section being provided with an upper recess, a lower nose and an arm extending rearwardly from said nose,and a spring adapted forattachment to the run ning-gear, which spring extends across the upper surface of said arm, for the purpose described.

3. In a thill-coupling, the combination with a body-section comprising a bottom orbase plate adapted for attachment to the runninggear of a Vehicle,and ears projected upwardly from the forward portion of said base-plate, of a locking section comprising a barrel 1oa pivot pin passed through the ears of they body section and through the barrel of the locking-section, the locking-section being provided with an extension at the forwardbelow the barrel, which extension has a rewardly-extending arm atits bottom portion,

and a spring adapted for attachment to theV running-gear, which spring is in engagementv with the upper surface of the arm of the lock- Y ing-section of the coupling, asdes'crib`ed. et. In a thill-couplin g, the combinatiomiivith` 'a body-section comprising abottom or base f plate adapted for attachment to the running- L gear of a vehicle, and ears projected upwardly f from the forward portion of said base-plate, Y of a locking section comprising a barrel lo-r cated between said ears of the bodysection,a v

pivot-pin passed through the ears ofthe body-r section and through the barrel of the lockingf section, the-locking-section being provided with an extension at the forward portion of the barrel, projecting downwardly below the barrel, which extension has a recess formedin Y its upper surface, a forwardly-extending nose at itslower end, and a rearwardly-extending arm at its bottom portion, a spring adapted for attachment to the runninggear, which spring is in engagement with the upper surface of the arm of the locking-'section of the coupling, and a thill provided 'with a foot having anV opening therein, the bottom Wall of the opening being inclined, the upper Wall of said opening of the thill-foot being adapted to engage with the lower wall of the recess in the locking-section of the coupling, the lower Wall of said opening in the thill-foot being adapted to engage with the nose onsaid locking-sectionof the coupling, as described.
