CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 661,002, dated October 30, 1900. Application filed July 27, 1900. Serial No. 25,040. (No model.)

To a, whom it may concern:

Be it known that I, CHARLES SOHLARED, a citizen of the United States,residingat Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful improvements in Car- Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates more particularly to the type of coupling known as the Janney.

The object of the invention is to provide an improved locking and setting device of simple and economical construction for the movable part or knuckle of such a coupling, whereby the cars can be an tomatically coupled and locked when coupled and unlocked and simultaneously reset for coupling.

The invention consists, primarily, in a locking-pin having attached thereto a pivoted lever with a cam e ge adapted to act on a tongue of the knuckle to throw the knuckle or movable jaw to open or uncoupled position when the said locking-pin is lifted, said pivoted lever being actuated by the contact of its inner edge with a surface in the cavity of the coupling-head or draw-bar. The knuckle-operating lever is also made with a tooth adapted to engage a seat or notch in the draw-bar to support the locking-pin in its elevated position.

In the accompanying drawings, showing an embodiment of my invention, Figure 1 is a vertical sectional view taken on the line a: 00 of Fig. 2. Fig. 2 is a horizontal sectional view taken on the line y y, Fig. 1. Fig. 3 is a top or edge view of the removed knuckle on a smaller scale. Fig. 4 is a View looking to the right of Fig. 3. Fig. 5 is a vertical sectional View of the knuckle setting and locking pin. Fig. 6 is a view of such device looking to the right, Fig. 5.

In the several views, 1 designates the stationary part of the draw-head, which is recessed horizontally, as indicated at 1*. This stationary part is also made with a vertical opening for the reception of the locking-pin. In the horizontal recess is hinged at 3 the knuckle or movable part of the coupling-head 2, havingatongue 2 formed asapart thereof.

The locking-pin comprises a frame 4, having a downwardly-extending leg 4 at its innerside and a shorter downwardly-extending flange or projection 4", that has its inner side inclined, as shown. Pivoted in the rear side of the locking-pin is a lever 5, having at its forward side a cam edge 5, adapted when the pin is lifted to act'on the tongue 2*, and at its rear side a cam edge 5*, adapted by contact with a surface or wall 1 in the drawhead to force the said lever outward, and therefore the tongue 2 of the knuckle in the same direction. The lever 5 is made with a tooth or point 5 at its lower extremity to engage a seat or notch 1 in the stationary .portion of the draw-head when the lockingpin has been lifted to the uncoupling position. This engagement of the lever with the notch 1 sets the pin in the uncoupled position and holds or supports it there until acted on by an approaching coupler.

The frame of the locking-pin is furnished at its upper end with slotted walls 4,and sup ported hingedly in a link 6, passed through the slots of these walls, is a curved pin 7, the lower end of which works through an opening 4 in the frame 4. When the couplingpin is down, the end of this curved pin 7 protrudes by gravity through the opening 4 and under the upper wall of the horizontal cavity of the draw-head, and thus serves as a latch to prevent the locking-pin from jolting out of its place. The link 6 can beconnected to one end of aleverextending to the side of the car, so as to be within reach of the trainmen without the necessity of going be tween the cars; but I do not show this lever in my drawings, nor do I make any claim of novelty to such lever, because it is well understood and is common to many forms of coupling.

The upper end of the knuckle-operating lever 5 is formed with a handle 5, that can be employed to lift the locking-pin if the link 6 should be damaged so as not to afford suitable place whereby it may be grasped. Ordinarily the locking-pin is lifted by means of the link 6, and the first lifting movement withdraws the latching-pin 7 ,so that the coupling-pin can be further raised to cause the le ver 5 to act on the tongue 4. When the coupling-pin has been lifted to its full extent that is, the extent permitted by a cross-pin 4 in the leg 4-the tongue 2 is pushed outward until the lower edge of the lockingflange 4t rests on the upperside of said tongue. In this position the cars can be separated, and the parts are set in position for recoupling. The coming together of two couplings the shop for repairs.

What I claim, and desire to secure by Letters Patent, is

1. In a car-coupling, a knuckle having a tongue thereon, a pin having a tongue-locking flange or projection on one side and a ton rue-operating, lever on the opposite side, combined with a latch attached to the pinlifting device for automatically latching the aforesaid pin in its tongue-locking position, substantially as described.

2. In a car-coupling, the combination of a knuckle havinga tongue, a movable lockingpin therefor, and a lever pivoted to the locking-pin having a cam edge to operate the tongue, and a cam edge to contact with the draw-head when lifted to move said lever against the tongue,substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES SGHLARED.
