CAR-CCU PLING.

SPECIFICATION forming part of Letters Patent No. 504,085, dated August 29, 1893.

' Application filed May 4, 1893. Serial No. 472,930. illo model.)

To all whom it may concern.-

Be it known that I, FREDERICK JAGOB,'3. c tizen of the United States, residing in the city of Newark, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Car- Couplings, of which the following is a specification.

This invention has reference to animproved car-coupling by which the coupling of the cars is accomplished by the force of gravity, so as to dispense with the use of springs, screws and other parts that are liable to wear out by use and which is so constructed that a double interlocking of the draw-heads takes place, and that the uncoupling-of the cars can be accomplished either from the side, platform or top of the car without danger to life or limb. The draw-bars can also be used with the ordinary pin and link-coupling, so as to permit of. coupling with cars having the old style pin and link while the draw-heads adapt themselves readily to difierent angles of inclination toward the drawbars when rounding curves, so that a steady and reliable connection of the cars is obtained.

The invention consists of.a car-coupling which consists of a drawbar which is open at Y the sides and has a rounded-0d face-plate with an opening for the ordinary link, the upper part of the face-plate being made tapering at both sides, so as to support a saddle-piece which is inclined in opposite directions and connected by a swivel-pin with the yokeshaped top-piece of a detachable draw-head which rests on the saddle-piece. The drawhead is open at the center for the face-plate of the draw-bar and provided with straight face-plates at both sides of the draw-bar. A weighted push-piece is hinged to the rear-side of. the drawhead, its lower end projecting through an opening in the draw-head and having a bent-up stop-lug back of the opening,

against which lug abuts the arm of a pivoted latch which is made integral with a coupling hook at its outer end, while a weighted latchlever is fulcrumed to said latch and connected by a pivot-link with a transverse uncoupling lever fulcrumed to the top-piece of the drawhead. The coupling-hook extends around the edge of the draw-head to the front of the same, so as to couple with the draw-head of the car to be coupled, when the latch is dropped in its lowermost position. The latch is operated in connection withthe push-piece, so as to retain the coupling-hook in coupled or uncoupled position, as required.

The invention consists further of certain details of construction, which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1, represents a side-elevation of my improved car-coupling, showing the parts in uncoupled position. Fig. 2, is a plan-view of Fig. 1. Fig. 3, is a front-elevation of the draw-bar and draw-head, ready for coupling. Fig. 4, is a side-elevation of the car-coupling showing the parts in coupled position. Fig. 5, is a planview of Fig. 4. Fig. 6, is a front-view of the draw-bar and draw-head in coupled position. Figs. 7 and 8 are rear-elevations of the drawhead, showing the push-piece in vertical transverse section, and the parts respectively in uncoupled and coupled position. Figs. 9, and 10, are vertical transverse sections respectively on line 9 9, Fig. 7, and 1010, Fig. 8, and Fig. 11, is a detail horizontal section on line l111, Fig. 8.

Similar letters of reference indicate corresponding parts.

Referring to the drawings A representsa draw-bar, whichis preferably made of platesteel, open at the sides and provided with a rounded-01f face-plate at, having an opening of sufficient size to permit the introduction of a link when the draw-bar is to be used with the ordinary pin and link coupling. The draw-bar A is attached to the under side of the car-body in the usual manner and cushioned by suitable springs. The front or faceplate a of the draw-barA is extended in upward direction and inclined from the center clined top-part of the face-plate a, said sadroo dle-piece being provided with flanges b b at both sides, so as to rest steadily by gravityon the sides of the top-plate of the draw-bar. When the draw-bar A is made specially for this construction,the saddle-piece is made in one integral piece with the draw-bar. The saddle-piece Ois likewise provided with a hole for the swivel-pin B. A draw-head 'D rests on the saddle-piece C and is connected with the saddle-piece and draw-bar by the pin B, it being provided with a backwardly-extending yoke-shaped top-part d that correspondsin cross-secti on with the shape of thesaddle-piece C. Thelower part of the draw-headDis also provided with a yoke-shaped bottom-part1 d which is like the top-part d, engaged by the pin B, as shown clearly in Fig. 1. From the yokeshaped back and bottom-parts d d of each draw-head D extend horizontal side-portions or wings (1 which serve to reinforce the faceplates. The wings d at one side of the drawhead are connected at the outer edges by a vertical plate (Z which is provided with an oblongopening'dflas shown clearly in Figs. 1,. 3, 7'and8. The draw-head D is preferably made of strong plate-steel and is bent into shapeby'means of suitable diesso as to fit over the saddle-piece C of the draw-bar, it being open at its middle-portion, so as to permit the rounded-oft face-plates to project slightly through the open portion of thedraw head D: To the yoke-shaped top-part ofi the draw-head D is fulcrumed an uncouplingrlever E, which is connected by a link 8 with a level-E, that is weighted at its outer end and fulcrmned to a latch F, whichis pivoted at itsinner end to the rear-side of the draw-head- D. Theouter end of the latch F is bent in the shape of a hook F that extends over the. edge and over thefront of theidraw-head. D,

asshown clearly in Figs. 1, 3 and 6. The latch F is'provided below its pivot with a downward-extending arm f, that serves to engage an upwardly-bent lug got the weighted pushpiece G, which is pivoted at its upper end to ears at the under side of one of. the lateral wings d of the draw-head, while the lower end projects through an opening in the. faceplate of the draw-head D to the outside of the same, the lower end being provided with a suitabl'ehead or enlargement g, as shown in Figs. 1,2 and 3 and on alarger scalein Figs.

9, lO and 11. The upwardly-bent lug g serves as a stop by which thepush-piece G is prevented from being forced by its weight to too great a distance beyond the face of the drawhead, while the head g limits the inwardmotion of the push-piece G, when the draw-heads come in contact with each other. The uncoupling-lever E extends transversely across thedraw-bar and is made of sufficient length to permit the operation of the same from the sides, platform or top of the car, so that the brakeman is not required to pass in between thecars when coupling the same.

Operation of coupling: When the cars are to be coupled, the parts are placed inuncoupled position and the coupling-hook of each draw-head is placed in raised position by the uncoupling lever E and retained in this position by the inner end of the weighted latch-lever abutting against the lug g of the push-piece G, as shown in full lines in Fig. 3 and in dotted lines iniFig. 7. The head g of the push-piece G projects to its full extent beyond the face-plate of the draw-head. When, by the approach of the cars, the faceplates of the draw-bars abut against each other, the drawheads of both couplings form contact with each other, and the projecting heads of the push-pieces G are pushed inwardly, sothat the inner ends of the weighted latch-levers are released from the lugs g and dropped by their weights into the lowermost position, asshown in Figs. 6 and 8. In this position the coupling-hooks of the latches F engage the opposite sides of the draw-heads, so that they are locked together at two diagonally-opposite points, as. shown in Fig. 4. When the cars are to be uncoupled, each uncoupling lever Eis turned on. its fulcrum in such a position, that the latch-lever E is.

raised into the position shown in Fig; 3 and in dotted lines in Fig. 7.. As the face-plates of the draw-heads are still in contact with each other,.the inner end of thelatch-lever E" engages the bent-up lug g of the pushpiece G. As soon as the draw-heads are moved away from. each other, the push-pieces G are dropped by gravity until stopped by the contact of the-lugs g with the face-plates of the draw-heads D,.so that the arms fof the latches F abut against the lugs g,.as shownin Figs. 7'and 9.. As the coupling-hooks F are withdrawn from. thefttce-plates of thedrawheads, the cars are ready to be uncoupled. The lower endsor headsG of the push-pieces G are projected beyond the face-plates of the draw-heads to their full extent. When the cars are coupled. again,.the heads ofi'thepushpieces are pushed back,.tlie latches arelreleased and all the parts of the coupling, namely,.the uncoupling lever E,.the couplinghook F', the latch F' and the latch-lever E? disconnected, the parts are set againby the v uncoupling lever from the coupled or lowermost position into. the uppermost or uncoupled position, as shown in Fig. 3'-

Advantages: Myimprovedcar-couplinghas a number of advantagesas compared wiiththe car-couplings heretofore in use, to wit:

First. Tlie stead'y connection of the. couplings by the face-plates of' the draw-heads.

"Second. The yielding. of the draw-heads when the cars approach each other for coupling. on a curve, soas to facilitate the connection of the parts. heads also takes place when the cars pass This yielding of the drawaround curves, which is accomplished by-the swivel-pins of the draw-heads, on which the draw-heads swing. During the swinging motion of the draw-heads, when rounding curves, the yoke-shaped top-parts of the same ride on the saddle-pieces of the draw-bars and are returned to their original positions by the force of gravity, the yoke-shaped top-parts of the draw-heads and the saddle-pieces of the draw-bars securing always the proper alignment of the parts, as soon as the cars have passed around the curve.

Third. As each draw-head is provided with a coupling-hook, the double locking of the drawheads at diagonally-opposite points of the same is produced, so that the accidental uncoupling of the cars is prevented.

Fourth. The uncoupling can be accomplished from the side, platform or top of the car without the slightest danger to the brakeman operating the same.

Fifth. My improved coupling can be used for coupling with the ordinary link, as the link can be readilyinserted through the opening in the rounded-off face-plate of the drawbar and coupled by the swivel-pin of the draw-head, which pin is dropped through the link and draw-bar and becomes thereby the coupling-pin for the link, a reserve-link being preferably carried on each draw-bar for this purpose, as shown in Figs. land 4.
