SPECIFICATION forming part of Letters Patent No. 358,150,V dated February 22, 1887.

Application filed June 16, 1856.

T all whom iz; may concern.-

Be it known that we, J AMES L. DowNrNe and SAMUEL R. WARD, citizens of the United States of America, residing at Richmond, in the county of McHenry and State of Illinois, haveinvented certain new and useful Improvements in Anti-Rattlers and rPhill-Couplings, of which the following is a specification, reference being had therein to the accompanying drawings.

rllhis invention pertains to improvements in that class of devices which we term anti-rattlers77 for carriages andthil1-couplings, having for their joint object to provide the ready adjustment or holding of the thills while coupling the same to the axle, aswell as to prevent the rattling of the same, and to permitY the ready attachment and detachment or coupling and uncoupling of the thills, and the invention consists of the combination of parts, includingtheir construction, substantially as hereinafter` set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a plan View of my improved combined antirattler and thill-coupling. Fig. 2 is a side view thereof. Fig. 3 is avertical section taken through the coupling contrivances, including the bolt.

' the same, and Figs. 5 and 6 are detail views one end with a vertical ear-like apertured plate,

A', which stands `just outside of the one end of the thill-coupling bolt. To the opposite end of the bar a s applied a second vertical earlike plate, A2, said end of transverse bar a having a rearward extension or arm, a', projecting slightly upward, while the said ear-like plate A2 is of a width or slightly rearward extended to permit it to fit against said extension a' of the bara and to receive and allow of the pas- Fig. 4 is a longitudinal section of Serial No. 205.325. (Nn model.)

sage therethrough of a pintle or pivot, a2, riveted to the extension a', and upon which is pivoted or hinged the plate or ear A2. The plate A2 has its upper rear corner slightly flared outward from its outside, -forming a dange, a3,

thereof also has the effect to broaden the back edge at said corner of the plate, whereby the latter is adapted to permit of the convenient application of pressure thereto by the finger in forcing or moving it out of alignment with the head of the coupling-bolt, to allow of the withdrawal of the latter, and of a like application of pressure thereto by the thumb in forcing or returning it to its former or normal position. The plate A2 is provided with two stops, at a5, one projecting from the upper rear edge of its slightly rearwardlyextended or wider surface, which, as the plate is turned or forced forward, enters a notch or recess, b, in the top forward edge ofthe extension a ofthe bar a, arresting further movement in that dithev plate A2 projects from the bottom inner edge, near the middle of the said plate, and as the latter, after having been moved forward, is moved rearward or returned to its former position enters a notch or recess, b', in the lower forward edge of the extension a of the bar a, thus limiting further movement in that direction of the plate A2.

In the transverse bar a, about at the center, is a socket, d, opening at the end thereof next to the plate A2 and adapted to receive a spring (helical, preferably) and a ball or spherical catch, o?, seated or cushioned upon said spring and projecting a short distance from or beyond said end of the bar a, to permit of contact with the plate A2, and by its spring-,pressure caused to press upon the latter'.

rIhe plate A2 is provided with a vconcavity or a proximate hemispherical socket, e, coincident with the spherical or ball catch d', and into which springs or snaps the normally-projecting portion of the spherical or ball catch as the plate A2 is moved to its normal position, to effectively secure or fasten the said plate in its said normal or holding position. The primary object or joint use of the ears or plates A A2 is to prevent the accidental displacement of and liability of losing the thillthereat, which outward daring or iianging coupling pin, while at'the same time avoiding rection of the plate A2. The other stop, ai", of

vthe screw-threading of the pin, and conseand having its inner end pointed or taperingand entering a socket in the usual anti-rattling elastic cushion, C, interposed between the eye and inner end ofthe thill, being conformed to the intervening space between said parts, as shown.

D is a metallic plate arranged to rest or bear against the under side of the cushion O, the same having a central opening, e, through whleh the point or tapered end ofthe thumbscrew B passes, while at the base or inuerend of the taper of the point of thescrew is a shoulder, which rests or bears' against the plate D, thus applying and distributing the pressure of the screw upon the said cushion in order to fully utilize the cushion in preventing the rattling of the thill. The tapered point of the said screw may be triangular in crosssection, as may be also the socket of the cushion C. rlhe plate D is provided with teats or pointed projections g g. to secure or connect it to the cushion, said teats or points being formed, it may be, by punching the same out of the plate itself, as shown, or theyT may be otherwise )roduced, a second plate, D', similarly provi ed with teats or points g' g, entering and securing the said plate to the upper side of the cushion or rubber C,`whieh plate is designed to take up wear that would otherwise be experienced by the rubber, and prevents the adherence or sticking of the rubber to the thill-eye, which would result if they were permitted to he in direct contact with each other.

It will be understood that we do not restrict ourselves to the details of construction of the other parts as herein shown and described, as it is obvious that the same may be varied or changed without departing from the spirit of our invention.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is-

l. The combination of thc yoke-plate having a cross or transverse bar provided at one end with a iixed ear-like vertical plate and at its opposite end with a pivoted ear-like plate and the spring-actuated spherical or ball catch, substantially as shown and described.

2. The yoke-plate having at its forward edge or end a transverse socketed bar containing a spring and a spherical or ball catch, which bar also has at its one end an ear-like plate, in combination with the additional ear-like plate pivoted to an extension of said bar and provided with a eoncavity, substantially as shown and described.

3. The eombination,with the yoke-plate having a transverse socketed bar, the spring, and the spherical orball catch, ofthe ear-likeplate pivoted to said bar, substantially as shown and described.

4. The combination, with the spherical or ball catch contained in a transverse soeketed bar of the yoke-plate, of the ear-like plate pivoted to an extension of said yoke-plate and having a concavity and provided with stops entering notches or recesses of said extension, sulstantially as shown and described.

In testimony whereof we affix our signatures in presence oftwo witnesses.
