CAR-COUPLING.

SPECIFICATION forming part of Letters Application filed June 8, 1886.

To all whom it may concern.-

Be it known that I, WILLIAM A. MITCHELL, a citizen of the United States of America, residing at Lawrence, in the county of Kaufman and State of Texas, have invented certain new and useful Improvements in Oar-Couplings, of

which the followingisaspecification, reference being had therein to the accompanying drawings.

Tnis invention pertains to improvements in car-couplings, having for its object convenience in effecting the adjustment of the link with relation to the height of the draw-head of the approaching car and facility in coupling and uncoupling the cars; and to these ends the invention consists of the combina tion of parts, including their construction, substantiall y as hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a side view ofa draw-head and aportion of a house-car with my improved car-coupling applied thereto. Fig. 2 is a vertical longitudinal section taken th Fig. 1. Fig. 3 is a front view of Fig. 1,- and Fig. 4 is a plan view of the draw-head, showing in particular the lifting or elevating coupling-pin yoke.

In the embodiment of my invention Ichamber, as at a, the drawhead A, which is of ordinary construction, said chamber a opening from the upper side of the draw-head, and dis pose in the said chamber a the link-adjuster B, which is pivoted or hinged at its rear end to the drawhead and provided at its forward end with a pendent approximately-beak-like portion, 7), entering the coupling-link chamber at of the draw-head A, and adapted to act upon the inner end of the link, as presently explained. The forward end of the link-adj uster B is beveled or tapered upward, giving it a downward and inward inclination, to readily direct and guide the link to the bottom of its chamber as the link enters the latter. In the same (forward) end of the link-adjuster B is a central vertical groove or recess, 1/, for the re ception ofthe couplingpin D, passed, as usual, vertically through the draw-head. In-the bottom of the link-chamber d, at its rear end, is a rough the draw-head of into which the inner end of the coup- O is forced or depressed by the linkadjuster B, also as will more fully appear hereinafter. To the link-adjuster B is connected the one end of a bar or link, f, the latterpassing through an aperture or slot, f, extending from the bottom of the draw-head and up into the same to the chamber a. The lower or outer end of said link or bar f is pivoted or connected to a bar, E, the inner or rear end of which latter is bolted to the under side of the drawhead A, the bolt of which is also passed through the link-adjuster B, which latter, by means of the said bar E, is held in a depressed positionthat is, with its beak or pendant projecting into the link-chamber cl. It will thus be seen that if the link be thrust into the linkchamber of the draw-head it will strike against the forward beveled end of the beak of the link-adjuster B and be directed and guided by said bevel or inclination of the beak of the link-adjuster to the bottom ofsaid link-chamber and under the said beak of the link-adjuster into the cavity.

F is a rod for elevating or lowering the linkadjuster B, thereby raising or lowering the outer end of the link and adjusting its position so that it may readily enter the link-chain ber of the opposite draw-head, according as the height of the draw-head of the approaching car may demand. This link-adjuster-opcrating rod F is provided with a cam, bail, or crank, f having a stirrup or 1oop,f, through which the bar E is passed, and, as the one or the other of the handles 9 g of the rod F (one at each end thereof and at the sides of the car) is turned to the right or left by an attendant or train-man, it will act upon the bar E and force it downward or upward with the link or barf, which will lower or elevate the link-adjuster B, for the purpose aforesaid.

G is a yoke fitted upon a draw-head, A, and having a central aperture in its upper horizontal cross piece or plate in alignment with the coupling-pin passage of the drawhead, which aperture receives the couplingpin, the head of the latter holding it in posi tion in the yoke. To the lower ends of the side arms of the yoke G are connected the forcavity, e, ling-link ward ends of longitudinal narrow plates or bars G, which latter extend some distance rearward alongside of the containing-case of the draw-head, and are connected at their rear ends to a cross-bar, h, passed through and relatively fixed to the draw-head, and through slots 2' in the containing-case of the draw-head, whereby the draw-head may have a limited movement with the said yoke-connected bars or plates G within said case, as is usual in cars, whichforrn no part of my invention, and therefore no further reference thereto is required herein. In the event of the employment of my invention in connection with a draw-bar having a cross-bar at or near the rear end thereof, the longitudinal plates or bars G are attached thereto.

The yoke G has a pivotal or hinged connection with two links, j j, in turn articulated or pivoted to the free ends of two arms, 7a 7a, fixed to a rod or lever, I-I, journaled or pivoted to turn in strap-eyes is, fastened to the car-body. This rod or lever H is provided with a stop or projection, which, when the yoke G has been operated so as to actuate the coupling-pin and elevating-yoke, will press against the spring plate or holder m, fastened to they end of the car, the said stop being turned with the said rod from below to the front and upward against and pressing outward upon said spring plate or holder. The latter, with said stop, thus serves as a catch or retaining device for the rod or lever as against the turning of the rod when the hand isremoved from whichever of its two handles it n that may have been grasped for its operation, and as the coupling-pin is held in an elevated position, thereby effecting the automatic holding of the coupling-pin in its elevated position previous to the coupling of the cars.

For operating the coupling-pin-elevating yoke G from the top of the house-car, a rod, I, is connected to one of the fixed arms 70 of the rod or lever H, and extends a short distance above the top or roof of the car, the'samehaving been passed through guides and retainingeyes or keepers o, fastened to the end of the car.

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

1. In a car-coupling, the combination, with the draw-head, of the link-adjuster having a pendent beak and the link-chamber having a cavity immediately below said beak, substantially as and for the purpose stated.

ssoese 'vided with a groove or recess,

Y 2. The combination, with the drawhead, of

the link-adj uster having a pendent beak prothe link or bar secured in said recess or groove, and the bar connected to the draw-head and to said link or bar, substantially as shown and described. 3. In a car-coupling, the combination, with the draw-head, of the link-adjuster, with its pendent beak portion projecting into the linkchamber, head, acting downwardly and connected by a link or bar to said link-adjuster, substantially as shown and described.-

t. In a car-coupling, the combination, with the draw'head, of the link-adjuster having its beak projecting into the'link-chamber, the bar and the bar connected to the draw;

connected to the draw-head and'acting downwardly upon and connected by a link or bar to the said link-adjuster, and the rod having a cam, bail, or crank adapted to act upon said bar, substantially as shown and described.

5. The combination,with the draw-head, of the coupling-elevating yoke having side arms, the longitudinal plates or bars, the cross-bar passed through said draw-head, and to which said plates or bars are connected, and the rod or lever connected to links of said yoke, substantially as shown and described.

6. In a carcoupling, the combination, with the draw-head, of the coupling-pin-elevating yoke having a centrally-apertured upper crossbar, and its side arms connected to longitudinal bars connected to a cross-bar at the rear end of the draw-head,t-he links pivoted to said longitudinal bars, and the rod or lever having fixed arms pivoted at their outerends to the upper ends of said links, which rod or lever is provided with a stop bearing upon a spring fastened to the end of the car, substantially as shown and described.

7. The combination,with the draw-head and the pin-elevating yoke having links connected to the longitudinal bars thereof, of the rod or lever having a stop or projection, the spring plate or holder, and the fixed arms connected to said lever and links, substantially as shown and described.

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

J. A. SIMPSON, O. A. GOODWIN.
