SPECIFICATION forming part ef Lettere Patent No. 508,088, dated November 7, 1893.

\ Application filed May 31, 1893. Serial No. 47i|015. (No model.)

To wZZ whom t may concern:

Be it known that I, ELIAS COREY, of Omaha, in the county of Douglas and State of Nebraska, have invented certain new and yuseful Improvements in Car-Couplers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.J in whieh- Figure l is a perspective View of my improved car coupling applied to the end of a car, showing the pin-operating devices, and the pin coupled. Fig. 2 is a longitudinal central vertical section through the coupler and parts shown in Fig. 1. Fig. 3 is a horizontal sectional view through the draw-bar on line 3-3 Fig. 2. Fig. 4 is a transverse vertical section on line 4-4 Fig. 2.

My improved car coupling consists essentially in novel -devices whereby the pin is upheld until the link has entered the mouthA of the draw-bar, and then released to lock the link in position;l and whereby the pin is locked in place so long as the link is pulled outward thereagainst.

It further consists in the novel devices for raising the link and upholding it in uncoupled position, and in certain other novel details of construction and combination of parts which are hereinafter described in detail and summarized in the claims.

Referring to the drawings by lettersz-A represents the draw bar which resembles an ordinary linkland-pin-couplingdrawbar, but has two directly opposed openings B, B, in its opposite sides. These openings are about as deep as the interior opening of the draw bar, and are about in line with the pin openings a, a, thereof as shown.V

C, C, are two hinged jaws which are seated in recesses b, b, in the sides of the draw bar adjoining openings B, and are pivoted to the draw bar at their rear ends in any suitable manner so that they swing vhorizontally toward and from each other. These jaws have enlarged heads c, c, on their front ends which, when the blocks are closed against the sides of the draw-bar, project through openings B, B, into the interior of the draw bar as indie cated in Fig. 1; these heads are rounded on their front edges as at c so that a link entering the draw bar will be directed between the heads c, and these heads, when 'the jaws are closed against the sides of the draw barstand so near together that the link in entering the `draw bar will force them apart as indicated projecting plates c2, which, when the. jaws areclosedalmosttouch eachother,and partly close the upper pin opening a, and the pin cannot pass therethrough when the jaws are closed. The pin P may be an ordinary straight coupling pin, or of anyshape desired, and is adapted to lock the link as usual. To insure the perfect working of the coupling it is desirable that the upper pin opening a be so deep that the pin will be kept in upright position so that Jas soon as the obstructing plates c2 are removed, the pin will drop down through upper opening ot and engage, lower opening ct also. If necessary a tube A may be cast on, or vsecured to the top of, the draw bar around the upper opening a to guide the pin. When a coupling is to be effected, the pin is set inupper opening aj'and is upheld by plates c2. Then as the link L which is fast to the draw bar of the adjoining car enters draw barA it forces jaws C apart as its end passes in rear of openings a, and thereby separates plates c2 whereupon pin P drops in place through the link and locks the latter in position, as usual. As soon as the link is drawn forward against the pin, it allows the jaws, owing to their rounded heads, to partly close, until plates o2 bite against the sides of the pin. Then it will be difficult if not impossible to remove the pin until the jaws are separated by pushing the link inward. The link can be inserted by hand when it is desired to conneet a link to the draw-bar preparatory to coupling with another car. The jaws biting the sides of the linkwhen it is inserted in the drawbar enable the link to be adjusted and held at various angles, but to insure the proper holding of the link in coupling, I make a short recess l in the rear end of the mouth IOO of draw bar near the floor thereof into which the end of link may be inserted, and it will then be held in proper position for entering another draw bar in coupling.

In order to operate the pin from the side of car, and to hold it uncoupled even when a link enters the draw bar, I have the following devices:-A lever D is pivoted at one end between brackets E on the end of car above the draw bar and its outer end is connected by a chain or in other suitable flexible way to the top of pin P. The lever has a transverse pin d in it which is adapted to engage shoulders or lugs e on the brackets and prevent the outer end of leverdropping too low. A shaft F is secured transversely across the end of car above the draw bar and below lever D being journaled in suitable brackets E and E, as shown, and having crank handlesfon its ends by which it can be rocked. Au arm G is fixed on the shaft between brackets E', E, and-below lever D, and is of such length that when the shaft is properly turned, arm G engages thc under side of lever D and raises the latter thereby lifting the pin P out of engagement with the link and above plates c2. By turning shaft F sufficiently the end of arm G will engage a notch d in the lever, and thereby lock the parts in such position, until the shaft be forcibly turned back so as to lower the arm.

The operation of the parts and the utility of my improvements will be readily comprehended from the foregoing description and drawings.

Having described my invention, what I claim as new, and desire to secure by Letters Patent thereon, is

1. The combination of the draw bar with pivoted jaws at opposite sides thereof beveled on their meeting faces, and plates attached to said` jaws adapted to uphold the pin until a link enters the draw bar and separates the jawsand to bite the pin when it falls, substantially as and for the purpose specified.

2. The combination of the draw bar having openings in its sides, with opposite springcontrolled jaws pivoted in said openings and projecting into the mouth of draw bar rounded on their front faces, but not contacting, and plates connected to said jaws projecting into the4 draw bar and adapted to uphold and bite the pin, substantially as described.

3. The combination of the draw bar having openings in its sides, the swinging jaws connected thereto projecting through said openingsand rounded on their frontinner faces but not contacting, and plates on the top side of said jaws adapted to uphold and bite the pin, substantially as and for the purpose set forth.

4. The combination of the draw bar having openings in its sides, and ailink recess at therear end of its throat, with swinging jaws in said openings, and pin supporting and biting `plates attached to said jaws, all constructed substantially as and for the purpose described.

5..The combination with the pin, the lever connected thereto at one end and hinged to the` end of the car, a shaft underlying said lever, and an arm on said shaft adapted to lift said lever when the shaft is rocked and to uphold the pin in uncoupled position, substantially as described.

6. The combination of the draw bar, the coupling pin, the lever D,brackets E, E rock shaft F, and arm G, all constructed substantially as and for the purpose set forth.

7. The combination of the draw bar A havling openings in its sides, the tube A surrouuding the upper pin opening the hinged witnesses.
