PORTER O. HAYES, OF BURGHILL, OHIO, ASSIGNOR OF ONE-HALF TO CLINTON H. DRURY AND GLENN O. BUSHNELL, OF HARTFORD, OHIO.

ANTIRATTLER FOR THILL-COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 663,884, dated December 4, 1900.

Application filed February 15, 1900. Serial No. 5,341. (No model.)

T all) whom, t 71u01/ concern;

Be it known that I, PORTER O. HAYES, a citizen of the United States, and a resident of Burghill, in the county of Trumbulland State of Ohio, have invented certain new and useful Improvements in Antirattlers for Thill- Couplings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art te which it appertains to make and use the same, reference being had to-the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a side elevation of the invention as applied. Fig. 2 is a central longitudinal section of the same. Fig. 3 is a detail view of the pivot-bolt D. Fig. 4 is a detail view of the wedge-form antirattler S. Fig. 5 is a detail view of the spring K. Fig. 6 is a side elevation of my invention as applied with a modified form of spring. Fig. 7 is a detail view of the modified spring.

The invention has relation to devices for preventing thill-cou plin gs from rattling; and it consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, the letter A designates the shackle to which the thilliron B, having the socket C, is connected by means of a pivot-bolt D, passing through the socket and bearings in the arms E of the shackle, which project forward from the back wall or bearing F of the same.

The bolt D is usually7 made with tapering ends G and perforations H, through which the ends of the vertical arms I of the spring K pass, serving to secure the bolt in place.

The perforations H may be made in the form of slots to allow for variations in the size lof the shackle,

L represents the clamp-plate of the shackle.

S indicates the curved tapering or wedgeform antirattler, the concave face m of which is recessed to seat the soft-rubber or leather cushion n, which is designed to engage the back of the socket or journal portion of the thill-iron O when the wedge is forced upward and forward. The back of the wedge F of the shackle.

ing is made in the double form of a convex flange p on each side of the part S, these lateral flanges being parallel and of equal inclined curvature. Forming a part of the antirattler is the transverse bar T, which is connected to the wedge portion by an extension or neck and extends laterally, forming arms V V, parallel to the ends G Gof the bolt and below the same.

The spring K is usually made in one piece, consisting of a rear loop portion Z, having a downward bend at ct, and coils b of the looparms around the arms V V of the wedge-bar T, said coils terminating on the vertical arms I, which pass through the perforations of the shackle-bolt, as already stated.

A bent-wire bracket w or other fastening device is provided to hold the loop end of the spring in fixed relation to the rear of the shackle, this latch device giving tension to the spring and at the same time being easily unfastened when it is desired to take out the shackle-bolt or antirattler for repair or other purposes. For this purpose the wire bracket or latch is usually made with a rearward bent loop portion to engage the rear end of the clamp-plate. When the wire latch is unfastened, the antirattler and spring can be removed in connection with each other, leav- -ing the coupling free.

When the rear loop of the spring is forced upward to secure tension and is latched in position, the spring acts to force the wedge from the antirattler upward, while its bearing against the wall ofthe shackle forces it forward, so that it is kept in iirm and continuous engagement with the back of the socket, holding the latter against the bolt, which is itself held 'from turning or otherwise moving by its engagement with the vertical arms of the spring.

It will be` noted that the convex flanges p at the rear of the wedge decrease the friction between the wedge and shackle and lessen the work required of the tension-spring to force the wedge upwardly.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s

l. An antirattler for thill-couplings,having a wedge-form upper portion provided with rear lateral convex flanges having a bearing IOO thill-iron, and having a lower portion pro- `vided with lateral extensions, and a wire spring coiled around said extensions, extended rearwardly and latohed to .the shackle and extended upwardly through slots or perforations of the coupling-pin, substantially as specified.

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

PORTER C. HAYES.

It is hereby certified that the residence of the assignee in Letters Patent No. 668,384,

for an improvement in Antirattlers for 'Phill-Couplings, Was erroneously Written in the grant Hartford, Connecticut,77 Whereas said residence should have been Written lllctrtford, Ohio; and that the said Letters Patent should be read With this correction raient No. 663,384.

` granted December 4, 1900, upon the application of Porter C. Hayes, of Burghill, Ohio,

` therein that the same may conform to the record of the case in the Patent Oee.
