THOMAS J. EDDLEMAN, OF FORT VORTH, TEXAS, SSIGNOR OF ONE-HALF TO JASPER XV. BURKART, OF SAME PLACE.

CAR-COUPLiNG.

SPECIFICATION forming part of Letters Patent No. 391,952, dated @Stoller 30, 1888.

Application tiled `May 1-1, IESS. Serial No. 273,818. (No model.)

To @ZZ whom. it may concern.:

Be it known that l, Encinas J. EDDLEMAN, of Fort Vorth, in the county of Tarrant and State of Texas, have invented a new and Improved Gar-Coupling, ot' which the following is a full, clear, and exact description.

The object ofthe invention is to provide an automatic ear-coupling which may be uncoupled from the sides of the ears, and which io will allow of a ear on which it is provided being coupled to a car provided with the ordinary link-and-pin coupling.

To these ends m'y invention consists in the construction and combination of parts, subij stantially as hereinafter claimed.

Reference is to be had-to the accompanying drawings, forming apart of this speciiication, in which similar letters of reference indicate corresponding parts in all the figures.

zo Figure l is a perspective view of aear-coupling constructed iu accordance with my invenliou. Fig. 2 is au inverted plan view thereof. Fig. 3 is a horizontal section, and Fig. 4 is a side view, of my improved coupling-pin.

In coustrnetinga car-coupling in accordance with my invention I form the draw-head A with an outwardly-flaring square mouth, a, leading to the interior of the said head for the eiiective guidance of the coupling-pin herein- 5o after described, and with an internal shoulder,

a', around the mouth.

The shoulder a of the draw-head formsastop for a spring-acted couplinggate, B, located within the draw-head, and which in the normal position effects a partial closure of the mouth a ofthe draw-head. The hinge-rod B ot' the locking-gate B extends upward through the drawhead and is provided on its outwardlyextendingendwithanelbow-lever,G,tothearms 4o 0f which lever are attached operating chains or cords D, which extend-outward to opposite sides oi the car, passing through guide-eyes E, secured to the front of the car adjacent to the side thereof. A ring or equivalent handle for the end of each operating-chain D serves as a convenient means for operating the said chains and also prevents them from drawing through the guide-eyes E. The guide-eyes and handle are, however, of small moment as 'against the lower bevel of the fiaring mouth having a bearing on the essential features of 5o the invention.

The form of spring employed in connection with the coupling-gate l and its connection to the gate may he varied in practice; but the preferred form consists of a spring-band, G, located on the underside ofthe draw-head, one y end being secured to the draw-head by forming the end of the spring with a loop or eye, g, which embraces a stud-pin, g', on said drawhead, a Cotter-pin, g2, serving to retain the spring in place, and the opposite end of the spring is suitably secured to the downwardlyprojecting end of thehinge-rod B', the arrangement being such that as thehinge-rod B is turned in response to the action of chains D on elbow-lever C, the spring G will be wound on thehinge-rod. Vith this arrangementitfollows that the spring G will normally act to force the coupling-gate B against the internal shoulder,

a, of the draw head, partially closing the en- 7c trance to the latter, as shown in l'ull lines in Figs. 1 and 3.

The coupling-bar H is provided with a lateral shoulder or hook, h, and at the extreme end the said pin is formed with four opposite bevels, t, terminating in a point. The top and bottom beveis are of unequal length, thelower one being of the greater length, the probabilities being in practice that the pin will strike 8o of the draw-head.

The opposite end of the coupling-pin is formed with a through vertical aperture or passage, ht', for receiving the coupling-pin of an ordinary coupling.

On the upper outer end ofthe hinge-rod B, below the elbow-lever C, are provided lugs or pins i), to which is hinged a gravity-catch, b', which as the said hinge-rod is turned suffieiently will be engaged by an inclined catchbloek, b2, secured to or formed upon the drawY head and the return movement ofthe hinge-rod be'prevented, the arrangement being such that when the hingerod B is turned sufficiently to cause the catch b to be engaged by the catch- 95 block ZXl the coupling gate B will have been swung entirely away from the mouth of the t draw-head into a recess, ai, formed in the inerior of draw-head, at one side, behind the hinge-rod B. With the coupling-gate in this latter position (which is indicated in dotted lines in Fig. 3) a clear passage is afforded for the entrance of an ordinary couplinglink, the draw-head loeinga formed with a vertical crcular passage, H', through top and bottoni for the coupling-pin for such ordinary link. It will therefore be seen that the coupler is adapted to be employed as an automatic coupler in connection with coupling-pin shown, and also adapted to couple with cars having ordinary link and pin.

Having thus described luy-invention, what I claim as new, and desire to secure by Letters Patent, is

As, an improvement in car-couplings hereinloefore described, the combination, with the draw-head A, and the link having a lateral hook h, and vertical perforation, of the later- 2c ally-swinging gate extending but part way across the mouth of the drawhead, the gate hinge-rod B, arranged vertically near one of the front corners of the draw-head and projecting at top and bottom thereof, and tvhelever z5 and coiled spring` applied to upper and lower ends, respectively, all as shown and described.

T. J. EDDLEMAN.
