ANTIRATTLER AND BOLT-LOCK FOR THlLL-COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 711,636, dated October 21, 1902. Application'filed March 19, 1902. Serial No; 98,978. (No model.)

To all whom it may concern:

Be it known that I, JACOB G. LESHER, a citizen of the United States, residing at Greencastle, county of Franklin, and State of Pennsylvania, have invented certain new and use Having the foregoing object in view, the invention consists of an 'antirattler attachment and bolt-lock comprising certain improved features and novel arrangements and adaptations of parts more fully set forth hereinafter and embodied in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation, with the vehicle-axle shown in section, illustrating the adaptation of the invention to an ordinary thill-coupling; Fig. 2, a front view; Fig. 3, a detail perspective view illustrating the device detached and showing the wear-plate in dotted lines, and Fig. 4 a detail of the wear-plate.

The numeral 1 designates the axle, and 2 the stock, while 3 is the clip or shackle, having the usual ears 4 and 5 for receiving therebetween the thill-iron 6, which is pivoted on the bolt 7, while 8 is the clip plate or yoke by which it is held on the axle. The head of the bolt 7 has in one side face a groove or notch 9.

The numeral 10 designates a wear-plate which is provided with the wear face or member 11, adapted to bear against the rounded portion of the thill-iron 6, and this Wear-plate is provided with the ears 12 and 13 and the arms orextensions 14 and 15, located below the ears.

jecting out therefrom, and the extension or The extension 14. has a lug 16 prolatter by the bail 20, while this spring-wire is formed into two coils 21 and 22, which surround the arms 15 and 14, and also has a loop 23, which bears against the ears 12 and 13 and the back of the wear-face, whereby the wearface is held against the rounded portion of the thill-iron 6 at all times. It will be observed that the coil 22 is formed in an intermediate portion of the wire and is held against lateral displacement from the arm 14 by the lug 16, while that portion of the wire after passing up and behind the wear-face passes down and crosses over the coil 21, as

tact with the rounded portion of the thillironand takes up any looseness of connection between the thill-iron and the bolt, and thus prevents rattling of the parts While the'bolt is locked, and hence can not jar loose.

One of the principal advantages of my construction over others heretofore known to the art is that provision is made for both taking up all the wear of the parts and locking them,

while the peculiar construction of the wear plate or member prevents any displacement of .the spring or the spring-coils, regardless of any hard usage to which the device may be put.

It will be obvious that the invention is in the nature of an attachment which can be readily applied to an ordinary form of thillcoupling without disturbing any of the parts thereof, it being only necessary to provide a bolt with a groove in its head to accommodate the locking end of the spring.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isr 1. In a device of the class described, the combination with a wear-plate having arms, one of which is provided with an outwardlyextending lug and the other being slottedor split, forming fingers, said fingers having outwardly-turned lugs, of a piece of springy or resilient material provided with coils which surround the arms, said resilient material extending back of the wear-plate and engaged therewith and having an end portion extending across the coil on the split arm and ben back and having a portion received in said slotted or split portion of the arm, the lugs on the arms being adapted to retain the coils on said arms.

2. In a device of the class described, the

combination with an axle clip orshackle and a thill, of a bolt connecting said thill and shackle, a wear-plate adapted to bear against the pivotal portion of the thill and provided With arms, one of which has an outwardlyextending lug and the other arm being split, forming fingers, said fingers having outwardly-extending lugs, a piece of springy material having a portion anchored to the clip and formed with coils which surround the arms, the coil surrounding the split arm being provided with an extension which engages with the bolt to prevent turning thereof and the other end of the resilient piece of material extending back of the wear-plate and holding it against the thill and terminating in a portion extending across the coil on the split arm, rebent and provided with an end which is received in the slot between the fingers.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

JACOB G. LESHER. Witnesses:
