ANTIRATTLING THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 651,072, dated J' une 5, 1900. Application tiled J'annaryIO, 1900. Serial No. 944. (No model.)

To LLZZ whom it' may con/08772,:

Beit known that I, GEORGE H. FERNALD, of North East, in the county of Erie, in the Sta te of Pennsylvania, have invented new and usefulImprovementsinQuick-Shift Antirattling 'Phill-Couplings, of which the following,taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to quick-shift antirattling thin-couplings; and my Objectis to improve upon the construction of patent issued to me under date of Julie 13, 1899, No. 626,862, having particular reference to the various details thereof.

I have found by practice that it is difficult to construct the forward end of the strapspring and pivot it stationary at the right point, so as to universally engage all of the thill-irons. To obviate this difficulty, I have elongated the eye in which it has heretofore been pivoted into a slotway, so as to allow the forward and curved end of the spring to engage the thill-iron and adjust itself by allowing it to move longitudinally by means of the elongated eye or slotway. I have also found that instead of using the lever used in Patent No. 626,862 I can cheapen the construction materially and produce better results by providing the clip with a nut having an upturned lip or by inserting a washer having an upturned lip or hook between the nut and the cross-bar to hold the bail which engages the rear end of the spring.

To the end, therefore, of improving upon said construction myinvention consists in the several new and novel features of construction and operation, which are hereinafter described, and speeiiicallyset forth in the claims hereunto annexed. It is constructed as follows, reference being had to the accompanying drawings, in which- Figure l shows a s'ide view of the antirattier complete in operation. Fig. 2 is a vertical section showing all of the'parts, the spring being released. I1`ig.3 is a section on linear Je, Fig. l, looking to the right. Fig. et is a view showing the washer provided with an upturned lip interposed between the nut and cross-bar.

Similar letters of reference indicate corresponding parts.

a shows the ordinary thl l-clips or thill-eycs, secured in the ordinary way to the axle a and provided with eyes a", and Z1 is the thill-iron, constructed in the ordinary way, adapted to fit and rest between the clips in the ordinary way, and b is the clip-bar, secured in the ordinary way.

c is a U-shaped bolt, one end c being adapt ed to pass through the eye of the clip and thill-iron for the purpose of holding them together, and the other end c" is provided with a recess d, which rests in the elongated slotway d in the spring e, or the end c instead of having a recess in its periphery may have an enlarged end and a rib back of it sufficient to form a recess to hold the bolt in the eye. The elongated eye d' is formed by securing to the strap-spring e the hook-shaped strip e, or it may be made in any other suitable manner. The forward end of the spring` e is curved, as shown atf, and the rear end is provided with a bail e".

The clip-bar is secured by bolts in the ordinary way, except that one of them (the nut g) is provided upon one edge with an upturned lip g, so as to engage and hold the bai1e",as Shown in Fig. l, the spring producing sufficient tension to hold it in position.

In Figs. 1 and 2 I show a nut upon the rear clip having a rearward projection provided with a recess g", which is adapted to receive the bail.

In Fig. 4 I show a washer h, having an uptnrned lip interposed between the bolt and the clip, which performs the same function. It will be observed that when the curved end of the spring e is placed upon the thill-iron it will adjust itself by the elongated eye d.

Having described my invention, what I claim, and desire to secure by Letters Patent,

isv l. Aquick-shiftantirattlingthill-coupling, comprising a strap-spring curved at one end,

nut secured to the axle, und adapted to re- 1o ceive said bail in combination, substantially as described for the purposes set forth.

In witness whereof I have hereunto set my hand this 20th duy of December, 1899.

and having e U-shaped bolt; engaging wiLh an elongated eye upon the forward portion of the spring, for the purposes set forth.
