AUGUSTUS J. STANLEY, OF COLORADO SPRINGS, COLORADO.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 509,457, dated November 28, 1893.

Application tiled August 30, 1893- Serial No, 484,388. (No model..l

To all whom t may concern:

Ble. it known that I, AUGUSTUS J. STANLEY, a citizen of the United States, residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented certain new and useful Improvements in (Jar-Couplings; and I do hereby declare that the following is a t'ull, clear, and exact description of the same, reference being had to the annexed drawings, making apart ot' this specification, and to the letters of reference marked thereon.

The present invention has for its object to provlde an automatically operating coupling for cars in which the action of the parts when the cars come together will be more effective and certain and the operation of coupling rendered less diiicult, and the invention consists in a coupling constructed substantially as shown in the drawings and hereinafter de scribed and claimed.

Figure l of the drawings representalongitudinal vertical section of a draw-head with my improved coupling, the coupling-pin and its connections also the end of the car or cartruck being shown in elevation. Fig. 2 is a transverse section taken on line x of Fig. l; Fig. 3 a detail View in perspective of the two jaws which are connected together and located within the draw-head; Fig. 4 a detail view in perspective of the connection between the lever and coupling-pin by which the latter is elevated to uncouple the cars.

In the accompanying drawings A represents the end of a caror car truck to which the drawhead B is suitably connected in any well known and desirable manner. The draw-head has an inclined base a and at its front a shoulder b and to the rear thereof is a semi-circular seat c which together form a support and guide for a jaw C which is suitably pivoted within the draw-head. The jaw C has a suitable opening d for the passage of a coupling pin D when said jaw is brought to a horizontal position or parallel with the upper side of the draw-head as shown in dotted lines of Fig. 1. Connecting with the jaw C through the medium of aknuckle-joint c, is alever-jaw E which also has an opening f to receive the end of the coupling-pin and also a mortise g to receive a suitable key F. The key F is considered of material importance in holding the jaws C E together by locking the latter inentioned jaw in position after the draw-heads have been coupled, thus preventing any binding of the lever-jaw against the coupling-pin by saidjaw moving forward and therebykeeping the pin sulhciently loose so that it may be removed at any time without difficulty.

The coupling-pin D has connected to it a link h and to this link is attached one end of a fulcrurn-bar G which bar is bent at an 0btuse angle and has at its inner end a suitable guide i' to receive a lever-rod H. This leverrod at its outward extremityhasa similar guide 7c for the fulcrum-bar and at its inner end connects with a crank-handle I for operating it. This connection between the coupling-pin and crank-handle forms a very perfect and easily operating means for elevating the coupling pin and allowing it to automatically descend without obstruction when the j aws are brought into position to have the holes therein registerwith each other and with the coupling-pin. The connection between the fulcrum-bar G and the lever-rod allows the bar to slide upon the rod sufficiently to prevent binding of the parts or lateral strain upon the coupling-pin or the link connected thereto. The fulcrum-bar havingits extensions at an angle as shown enables the coupling-pin to be more easily raised and descending by gravity more readily.

The lever-jaw E in the rear of its connection with the jaw C, is provided with a tongue K which bears against the under side of the drawhead and holds the lever-jaw in a horizontal "position at all times by preventing it from dropping down at an angle, the jaw E being supported by the lower jaw C. vThe sliding lever-jaw E has a forward bearing extension Z which projects beyond the front end of the draw-head when the cars are uncoupled.

In the act of coupling, the bearing extension Z receives the impact resulting from the cars coming together and the lever-jaw E forced farther into the draw-head as indicated by dotted lines in Fig. 1. This movement of the jaw is communicated to the lower jaw C throughthe medium of the knuckle-joint e by which the jaws are connected with each other, and the lower jaw as the result of said action IOO moves up to a horizontal position as indicated i will now drop down through the holes in the jaws and through the coupling-link of the adjacent car and thus couple the cars together.

Previous to the Operation above set forth, the coupling-pin is supported above the interior of the draw-head by the lever-jaw upon which it rests.

Many changes Or modifications in the several details of construction may be made with- -out departing from the principle of my invention so long as they come within ordinary mechanical skill.

I claiml. In a car-coupling, the combination with the draw-head of a sliding lever-jaw and a pivoted swing-jaw having openings for the reception of the coupling-pin and connected together by a knuckle joint, substantially as and for the purpose set forth.

2. In a car-coupling, the combination with the draw-head. thereof of two jaws, the lower One being pivoted to the draw-head and the upper one having a sliding motion and at its respective ends having extension to form a bearing at the front end of the draw-head and a supporting-tongue at the rear thereof, substantially as and for the purpose described.

3. In a car-coupling, the combination with a sliding jaw and a pivoted jaw, of a locking device for the upper one of said jaws, substantially as and for the purpose specified.

4. In a car-coupling, a draw-head having its lower side inclined downwardly and formed with a bearing-shoulder and semicircular seat, a pivoted jaw and a sliding lever-jaw connected together by a knuckle-joint, substantially as and for the purpose described.

5. A car-coupling, consisting of a drawhead, a pivoted jaw and a sliding lever-jaw located therein and connected together by a knuckle-joinh'and a locking device for the lever-jaw, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

AUGUSTUS J. STANLEY.
