CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 502,650, dated August 1p, 1893.

Application filed May l, 1893-. Serial No. 472.526. (No model.) i

Tou/ZZ whom it may concern:

Be it known that I, DAVID BELLoN, of Mc'- Kownville, in the county of Albany and State of New York, have invented new and useful Improvements in Oar-Couplers, of which the following is a specification.

This invention relates to improvements on the car-coupler for which Letters Patent of the United States, No. 390,944, were granted to me October 9, 1888; and the object of my improvement is to render my said coupler more effective in its operation. This object I attain by the means illustrated in the accompanying drawings, which are herein referred to and form part of this specification.

In said drawings, Figure 1 isa plan view of two of my couplers connected together. Fig. 2 is a side elevation of the same, showing portions of the adjacent ends of two cars connected by my improved couplers. Fig. 3 is an enlarged longitudinal section of the headV C is the draw-bar provided with a rear` wardly-extending center-bar, c,fltted to slide in said abutment-blocks. The side-bars, o',

of said draw-bar also slide in said abutment-A blocks and are arranged to keep said drawbar in a proper position; D a collar secured to the center-bar to form an abutment for springs, E, that are interposed between said collar and the two abutment-blocks B for keeping said draw-bar in its normal position.

A bumper-head, F, is pivoted to the outer end of each draw-bar C by means of sleeves, G, through whose opening a coupling-pin, I-l, can pass to engage in a corresponding opening of la coupling-link, I, when the couplers are to be connected together. The couplinglink I is arranged to enter a longitudinal mortise, J, formed'in the draw-bar C, and through the opening formed in the bumper-head F to enter said mortise. Each of the bumpering hook, L, arranged to engage with a flange 1, of'a conjoining coupler, as'set forth in my former patent above referred to. The hook L is provided with an eye, 2, to which may be attached a chainv or rope for the purpose of deflecting the bumper.- head F sidewise when it is required to disengage the coupler. Springs, 3, are arranged' to bearv against the opposite sides of the bumper-head, so as to normally maintain the latter in a central position, as shown by full lines in Fig. 1.

As far as above described, my car-coupler is substantially the same .as the one shown and described in the Letters Patent hereinbefore referred to, the essential differences between the two being that in my present device the draw-bar C is provided withalongitudinal mortise, J, formed in its outer end and iitted to receive a coupling-link, I, together with a few minor differences hereinafter described. The coupling-link I has, at

each end,an opening, 4, for receiving the corresponding coupling-pinI-I. The hook L of each coupler is provided with a rod, 14, which connects said hook with a crank, 5, of a transverse shaft, 7, journaled in bearings, 8, on the corresponding draw-bar'Og said shaft is provided with an arm, 9, which takes upon the corresponding end 4of a lever, 10, which is fulcrumed, as at 11, to the upper side of said draw-bar. The oppositeend of said lever is jointed by a pivot, l2, to the head of the coupling-pin H in such manner that an oscillation of lthe lever 10-produced by swinging the hook L laterallywill effect a lifting movement of said coupling-pin that will free it from its engagement with the couplinglink I.

The rearward extension of each draw-bar O has a chain, 13, or other suitable means, secured to it to form a connection between the two draw-bars of the same car, so that, when a train of cars is equipped with my couplers, a continuous connection between all of the cars of the train will be effected.

My invention operates in the following manner: Let it be supposed that two adjacent cars of a train are disconnected-the coupling-link I of one car projecting from the bumper-head F. Then, if one of said cars is pushed toward the other, or both of said i heads F is yprovidedwith aforwardly extend- Y IOO cars are put in motion toward each other, with sufficient force to enter the projecting coupling-link into the empty mortise of the draw-bar with whichthe connection is to be made, the coupling of said cars will be automatically effected. In accomplishing said movements the hook L-attached tothe free coupler-will take against the ange l of the coupler to which connection is to be made, and thereby deflect said hook laterally. The last named movement will raise the couplingpin II clear from the path of the incoming coupling-link I, so as to allow the latter to enter the empty mortise of the drawbar to which the connection is to be made; simultaneonsly the hooks L of the two couplers will become engaged with the flanges l of the respective bumper-heads, and the coupung-pin H-which has been automatically raised-Will be allowed to drop into the opening of the entering end of' the coupling-link I, and effect the coupling of the two cars.

That I claim as my invention, and desire to secure by Letters Patent, is-

The combination of a draw-bar provided with a longitudinal mortise in its outer end; said Inortise being arranged to receive a coupling-link, a bumper-head, jointed to said draw-bar by means of screw-threaded sleeves which are arranged toaflord the full height of said mortise between the adjacent ends of said sleeves; the latter forming an opening for receiving a coupling-pin; each of said bumper-heads being provided with a forwardly-projecting hook that is arranged to move laterally with the bumper-head to'which it belongs and is iitted to engage with the bumper head of a conjoining coupler, a rocker shaft journaled on said draw-bar and connected to the corresponding hook; said rocker-shaft having an arm arranged to automatically lift said coupling-pin when said hook is moved outwardly, and a couplinglink provided with openings iitted to receive the coupling-pins of two conjoining couplers, as and for the purpose herein specified.
