CAR-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 501,688, dated July 18, 1893. Application filed February 4, 1893. Serial No. 460.949. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE A. NOROROSS, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful Oar- Coupling, of which the following is a specification.

The invention relates to improvements in car couplings.

The object of the present invention is to improve the construction of car couplings, to enable cars to be readily coupled and uncoupled without going between them, and to facilitate the coupling of cars having drawheads at the same and different heights by readily guiding the link of one-of them into the other. i

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure 1 is a perspective View of a car coupling constructed in accordance with this invention, the link guider being in operative position. Fig. 2 is a longitudinal sectional view of the same, the linkguider being returned beneath the draw-head, and illustrating in dotted lines the link-guider extended and guiding a link. Fig. 3 is a transverse sectional view of the same. Fig. 4 is a detail View of a portion of one of the sides of the link-guider.

Like numerals of reference indicate corresponding parts in all the figures of the drawlngs. v

1 designates a link guider which is hingedly connected with a car 2 and adapted to be swung outward in advance of the draw-head 3 to form an outward and downward inclined chute to receive the link of an approaching car to guide the same into the draw-head 3, thereby enabling the cars having draw-heads at the same and different elevation to be readily coupled without necessitating going between cars and guiding the link by hand. The link guider, which may be connected in any manner with the car, is preferably suspended from the car by forwardly extending arms 4. and links 5; thc'arms are sigmoidally curved and extend below the draw-head 5 and the links are hingedly connected to the arms 4. and the link guider 1 by rods 7 and 8, which are transversely disposed. The rod 8 is arranged in a bore of the link guider. The outward and return swing of the link guider is effected by a rock-shaft 10 journaled transversely of the car and arranged above the draw-head and provided with a central depending crank bend 11,- which forms an arm and extends downward at each side of the draw-head and is connected hingedly to an eye 12 located on the inner face of and near the center of the body of the'link guider.

When the rook-shaft 10 is turned the link guider is moved outward with a curved move ment and is advanced to an inclined position in front of the draw-head as illustrated in Fig. 1 of the accompanying drawings; and when the rock-shaftis partially rotated in the opposite direction the link guider is returned to a position beneath the draw-head as illustrated in Fig. 2 of the accompanying drawings. When in an inclined position the link guider is adapted to receive a link at an elevation below or at either side of the draw-head 3 and guide the link upward and direct the same into the draw-head 3.

r The link guider consists of a body having a smooth outer face and provided on its inner face with transversely disposed tubular portions 13, preferably formed integral with the body and having slotted lateral extensions 14., on which are mounted yielding sides 15. The yielding sides 15 of the link guider have outwardly bent lower ends and are provided with opposite semi-circular openings 16 to receive the slotted lateral extensions of the tubular portion, and forming an integral fastening cross-piece 17 arranged in the slots 18 of the lateral extensions 14, and having attached to them the ends of spiral springs 19 housed in the tubular portions. The cross-pieces 17 are retained in the slots 19 by caps 20 screwing on the ends of the lateral extensions. The

spiral springs afford a yielding or elastic conneotion between thesides'15 of the link guider in order, when cars come together for coupling, to permit the draw-head of one car to approach and come in contact with the drawhead of the other car without damaging or in anywise injuring the link guider. A drawthe yielding sides, butthe sides 15,- which,

converge toward the upper end of the linkguider would not yield to a link, and the latter would beguided upward to the draw-head. The body of thelink-guider tapers toward the upper end in width and also tapers in thickness at its upper end to make it wedge-shaped; and the lower and wider end is beveled to avoid a shoulder. It will be noticed that the links 5 cause the link-guider to move in a curved path and any pressure on the front of the link-guider, when the latter is in operative position, would tend to first cause the link-guider to assume a vertical position with the upper end thereof supporting the link, and then increased pressure caused by further approach of draw-heads will return the same and force the link-guider downward instead of crushing it between the two draw-heads. This operation is assisted by the wedgeshaped upper end 21 of the body, which on being clamped would force itself downward.

The coupling pin is simultaneously raised with the outward movement or swinging of the link-guider by a-rock-shaft 22 journaled transversely of the car and provided with a central arm 23 connected with the'coupling pin 26. The ends of the rock-shaft 22 terminate in handles 24 which cross and are arranged above handles 25 of the rock-shaft 10. The handles 24 of the rock-shaft 22 being arranged above those of the rock-shaft 10 may be moved independently of the handles 25 to lift the link for uncoupling without operating the link-guider; but, by raising the handle 25 the handle 24 is also carried upward, thereby simultaneously raising the coupling pin and swinging the link guider outward.

The'upper end of the coupling pin 26 is arranged with a casing 2'7, consisting of a bot-- tom and upwardly converging sides and connected at the top by a link 28 with the outer end of the arm 23 of the rock-shaft 22. The casing has suspended within it an inverted cup 29, which when the coupling pin is lowered bears down upon the upper end of the same and enables the coupling pin to be shaken by the rock-shaft 22, in the same manner in which a coupling pin is shaken by hand in coupling to direct it into the coupling pin perforation at the bottom of the draw-head. By this construction the same control of the coupling pin is obtained at the side of a car as is had in coupling by hand between cars.

The inverted cup is provided at'its top withan eye 30 and issuspended in the casing by means of a horizontal pin or bolt 31.

The coupling pin may be held uncoupled for various purposes by a chain 32 arranged at each side of the car and having one end secured thereto and its other end provided with a hook and adapted to be passed around the handle 24 to hold the same elevated.

The link-guider may be retained securely beneath the draw-head, as illustrated in Fig. 2 of the accompanying drawings, and the coupling pin may be held in positive engagement with the link, without liability of being accident-ally thrown out of such engagement, bya latch 33, arranged at each side of the car and pivoted at one end and provided at the other end with a notch,adapted to engage a headed projection 34 of the car.

It will be apparent that the means for guiding a link into a draw-head and for raising and lowering a coupling pin are simple, inexpensive and effective, and that they do not necessitate going between cars in the coupling and uncoupling.

Any suitable means may be provided to enable the mechanism to be operated from the top of a car.

Changes in the form, proportion'and the minor details of construction may be resorted to without departing fromthe principle,'or sacrificing any of the advantages of this invention.
