"Tl-ilLL-COUPUNG.

' SPECIFICATION forming part of Letters Patent No. 509,017, dated November 21,1893. 7

Application filed July 22, 1893. Serial No. 481,202. (No model.)

To a whom it mag/concern: J Be it known that I, FRANK J. BUFF, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Thin-Couplings, of which the following is a description, reference beinghad to the accompanying drawings, which are a partof this specification.

My invention has relation to improvements in thill-couplings, more especially of a form known as anti-ratt1ers.

In the class of thill couplings in which forward-extending arms are provided having inward-extending lugs at their front ends to receive the eye of the thill, it is important that oneof said forward-extending arms should be made laterally adj ustable,'so as to provide for the ready insertion of the thill eye, and the accurate and even reception therein of the lugs. It is, therefore, the object of my invention to embody this feature in a simple and improved structure; and with this end in viewthe invention consists of the devices and parts as hereinafter described and claimed, or their equivalents.

In the drawings, Figure 1, is a vertical sectional view on the line 1-1 of Fig. 2. Fig. 2, is a horizontal section on the line 2-2 of Fig. 1. Fig. 3, is a vertical section on the line 33 of Fig. 1. Fig. 4, is a'perspective View of the adjustable arm, and Fig. 5, isa detail perspective view of one of the bushings inserted between the end of the thilleye and the arm. Like numeralsof reference denote like parts throughout the several views.

- Referring to the drawings, the numeral 1 indicates a clip adapted to be secured to the fore-axle of the vehicle. The forward leg of this clip is provided with a lateral extension 2, from which, in turn, extends forward an integral arm .3, provided at its forward end.

with an inward-extending conical or tapering bearing lu'g 4. A bolt-hole 5 passes through this arm and through the lug. The rear side of the forward leg of the clip is provided with a recess 6, having an inward tapering bottom, and inward tapering sides, as clearly shown in Figs. 2 and 3. V

The numeral 7 indicates a removable and adjustable arm, said arm having at its rear end an inward-extending integral lug 8, adapted to be fitted into the recess 6, and having its inner side face, and its edges, tapering or beveled to correspond to the tapersor bevels of the. bottom and bordering edges of the recess. The inward-extending lug is somewhat less in width than the arm of which it forms a part, whereby two shoulders 9, 9 are formed,

adapted, when the log is in place, to bear 'permit of the ready insertion and removal of the lug, inasmuch as when being inserted or removed the narrowest portion of the lug, both horizontally and vertically, is registering withthe widest portion of the recess. The forward end of arm 7 is provided with an inward-extending conical or tapering bearing lug 10, similar in all respects to the lug 4, said lug 10, and the arm 7 at this point being provided with a bolt-hole 11.

The numeral 12 indicates a thill, the thilleye 13 of which is in the form of a double tapering socket, that is, the tapers being from opposite sides inward to a medial or central point. These inward tapering portions of the thill-eye are lined with bushings 14, 14, of any suitable material, such as leather, rubber, or anti-friction metal.

In properly adjusting the device, one side of the thill-eye is passed over the tapering lug 4, and the rear inward-extending lug 8 of arm 7 inserted in its recess 6, the conical or tapering lug 10 ofv saidarm being passed into the opposite side of the thill-eye. After this a bolt 15 is passed through the registering apertures of the arm, and held in place securely by means of the end nuts 16, 16. The relative position of the parts as just described is shown clearly in Fig. 2.

In the form of construction herein shown and described, it will be seen that all strain directly on the connecting bolt is provided against, as the draft or pull of the thill is exerted against the conical lugs whereby wear on the bolt, and consequent rattlingof the parts, is prevented. Z a The bushings 14, 14 inserted in the thilleye, of course lessen friction between said thill-eye and the conical lugs, and to a great extent prevent wear between these parts. Any slight wear that may occur, however, oan be greatest strain is liable to occur, however, is

between the inner sides of the arms 3 and 7 and the ends of the=thil-l=-eye .11; order to take up this wear, allthat is necessary is simply to insert washers 17 between the parts referred to, as shown clearly in Fig!- 2"; one of" said washers being shown in the detail View Fig. 5. These Washers can be readily placed in position by-reason of" the'provisien-of the removable arm 7. pd J I It will be seen that I provide a thill cou-pling in which not only simplicity cheapness and general efficiency enter'asimportantfactors, but furthermore a construction Where. in the liability of rattling is reduced, to the, min mum.

Having thusdescribed my invention, What, I claim,and desire to secure by Letters Patent of theUnitedStates, is-

1. In a'thill coupling, the combination, of an axle clip having therea'jr side of its fore leg adjacent to the axle provided with a re; cess, and having anint'egral' arm] projecting forward from the frontface of the fore leg, said arnrhavinggan inward-projectingconical lug, an armprovided at its rear endj with a lug adapted to fit in the recess of the foreleg, j of the clip, and to abutagainst the axleg.andf z:

provided at its forward end with an, inwardextendizfigg'coiri'eal, lug; -a th illglg this eye thereof beingof doubleconical form' to receive the lugs, and a bolt passing through the arms andthrough said lugs, substantially as set forth.

2C In :a thi l l' coupling; the combination, of an axle'clip having the rear side of its fore leg adjacent to the axle provided with a recess,'said-' recess provided with an inward-tapering bottom and inward-tapering sides, the clipalsohaving an integral arm projecting 'for'ward from'the front face of its fore leg, asaid armhaving an inward-projecting lug, an arm provided at its rear with an inward- 3 extending lug, fitting the, recess of; the; fore leg of theclip. and; abutting against theraxle, ithe edgesand inner-face, of said lug, tapered f or beveled. toiregister with the corresponding bevels of thtelltecesszand. saidarm. also pr-oivided atits forward end with an inward-exv-- tending lug,a,th ill,, the eye thereof adapted to receive the inward-extending lugs at the forward ends of the arms, anda bolt passing through thearmsandforward lugs thereof,

substantially as set forth. I In testimony whereof I affix-my signature in presencelof two witnesses. v I
