CAR-COUPLING.

Specification of Letters Patent.

Patented Sept. 15, 1914.

Application filed February 24, 1914. Serial No. 820,397.

To all whom it may concern:

Be it known that I OHARLns SoHLAnnD, a citizen of the United States, residing at C0- lumbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Car-Couplings, of which the following is a specification.

The object of this invention is to provide an improved form of automatic car coupling of the J anney type in which the parts are few and of simple construction and efi'ective in operation.

The invention is embodied in the example herein shown and described and then pointed out in the claims.

In the accompanying drawingFigure 1 is a plan view looking at the upper side of the structure. Fig. 2 is a vertical section on the line w-x Fig. 1. Fig. 3 is a similar section on the line yg Fig. 1. Fig. 4 is a top plan view of the knuckle. Fig. 5 is an elevation of the left hand side of Fig. 4. Fig. 6 is a perspective view of the pin.

In the views 10 designates the draw head which has a draw bar 11 as usual. The draw head is provided with a knuckle 12 se cured in place by and pivoted on a pin 13. The knuckle has a heel or tail piece having an angularly extending hook-like portion that is flat on its upper side at 14 and curvedly beveled as at 14". The pin comprises a main bar or body portion 15 which is generally square in cross section but has one corner cut away as at 16, forming a shoulder 16* and a laterally extending foot portion 17 provided with an upwardly extending toe 18 having a shoulder or hook 19. The body of the pin works in a cavity in the drawhead, the latter being provided with a hole 20 permitting the extension of the upper end of the body of the pin above the draw head. The drawhead is also provided with an upwardly extending socket 21 into which the toe 18 extends when the pin is raised for setting it. The hole 20 is made of such capacity that the pin is capable of slight axial oscillation and the rear wall of the socket 21 is so positioned that the toe 18 when raised is thrown forward into position to permit the shoulder or hook 19 to drop upon and engage the upper rear edge or corner of the hook-like inner portion of the tail piece of the knuckle as depicted in Fig. 3.

The forward side of the foot portion 17 is beveled as seen at 17 and if the knuckle be in closed position the pressure of said beveled portion l? when the pin is raised beyond the pin setting position bears upon the terminal corner 14 of the bevel 14 of the knuckle and tends to throw the knuckle to open position.

In practice the pin is set when the knuckle is closed-as when cars bearing the couplings are coupledby raising the pin until the hook 19 is above the end of the angular tail portion and then releasing the pin which falls by gravity until the hook 19 is caught upon said angular tail portion. In this position the knuckle can be turned to open position'as when the cars are separated. If an uncoupled coupling has its knuckle in closed position it may be thrown into open or coupling posit-ion by drawing the pin sufiiciently upward to cause the beveled portion 17 a to act on the corner 14 and the beveled portion of the angular extension of the tail piece. IVhen the knuckle is closed the pin drops into position to lock it from opening, the wall 14 abutting against the pin to effect this result.

The pin can be operated by a chain attached to the eye 22 or by means of a lever 23 pivoted on a pin 24 in the lower end of the cavity of the draw-head. A lever, chain or other suitable device (not shown but well understood) can be attached to said lever 23 in the eye 25 on the free end of the lever.

The shoulder 19 of the pin is in a plane somewhat below that of the shoulder 16 on the body of the pin, and when the knuckle is opened and the hook-like extension of the tail piece passes from under the shoulder 19 and the pin drops a little but is still supported in elevated position by the engagement of the shoulder 16 with said hook-like extension. From this position the knuckle can be closed or turned inward and because the shoulder 19 is below the corner of the hook-like extension the pin drops into looking position when the hook-like extension is turned from under the shoulder 16.

The hinge pin 24 is made with a large head 24 projecting sufliciently to catch a broken or detached companion knuckle and prevent it from falling upon the track where it might derail cars or otherwise cause injury.

l/Vhat I claim is:

1. In a car coupling, the combination with a drawhead and a horizontally swinging knuckle having a heel, a locking pin having a body portion and an extension and means in the drawhead for compelling a rectilinear vertical movement of said locking pin, said means also permitting an axial oscillating movement of the body portion of said look: ing pin, said body portion having a shoulder to rest on the heel of the knuckle and said extension also having a shoulder to rest on the heel of the knuckle to support the same "in position to permit opening of the knuckle the resting point of the shoulder of the extension being below the horizontal plane of the resting point of the first mentioned. shoulder, and means in the drawhead to automatically cause said locking pin to horizontally oscillate on the axis of the body portion of the locking pin into setting position when the pin is raised.

2. In a car coupling, the combination with a drawhead and a horizontally swinging knuckle having a heel, a locking pin having a body portion and an extension and means in the drl whead for compelling a rectilinear vertical movement of said locking pin, said Copies of this patent may be obtained for the resting point means also permitting an axial oscillating movement of the body portion of said lock- 7 ing pin, saidbody portion having asho'ulder to rest "on theheel of the. knuckle and said extension also having a shoulder to rest on the heel of the knuckle to support the same.

in position to permit opening of the knuckle, the resting point of tension being below the horizontal plane of of the first mentioned shoulder, means in the drawhead to automatically. cause said locking pin to horizontally oscillate on the axis'of the body portion of the locking pin into setting position when the pin is raised, and said coupling pin also provided with a cam surface between the body portion of the pin and said extension to actuate the knuckle to throw the same to open position when the pin is raised beyond the setting position.
