CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 247,198, dated September 20, 1881.

Application filedFebruary 1,1881. (No model.) i

To all whom it may concern:

Be it known that I, IRVING W. KEITHLEY, of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Car-Couplings, of which the following is a specification.

The object I have in view is to produce a cheap, simple, and durable automatic carcoupling, which will be convenient in use, can be readily uncoupled, can be coupled with allsizes of links, and,when the automatic swinging pin is broken, can be used with an ordinary pin until again provided with an automatic pin; and my invention therein consists in the peculiar devices employed by me for this purpose, as fully hereinafter explained, and pointed out by the claims.

In the accompanying drawings, forming a part hereof, Figure 1 is a top view of the coupling; :Fig. 2, a vertical section of the same; and Fig. 3, a vertical section, showing the drawhead coupled with a short link by means of an ordinary pin.

Like letters denote corresponding parts in all three figures.

Ais the draw-head, havinga flaring mouth, a.

B is a swinging pin, which is pivoted at its upper end by means of a bolt, 11, between lugs C, rising from the draw-head at the center of its front edge. This pin is offset to the rear from its pivot, as shown by 0, and its body hangs down vertically into the draw-head, passing through a longitudinal slot, D, in the top of the draw-head, and into a slot, E, in the bot-- tom of the draw-head. The upper slot, 1), is made long enough so that the pin B can be swung entirely out of the draw-head, while the lower slot, E, need only be equal in length to the width ofthe swinging pin. This swinging pin rests against the ends at e of the slots, and the. strain upon the pin is all taken by the draw-head at the points (I 6, so that the pivotbolt 1) will be relieved from strain and will not be broken off or become bent.

The lower end, f, of the pin B is formed on acurve struck from the fulcrum b, and the inner lower corner, f of the pin rises above the upper surface of the bottom plate of the drawhead to a point just below the center of the end of a linkrestin g on the bottom of the drawhead. This peculiar construction is for the purpose of allowing the swinging pin to be raised when there is the least play between the link and the pin. The pin B is raised by suitable connection with the ring g, so that it can be operated from the top or side of the car.

The pin B can be thrown upwardly into the position shown in Fig. 3, and will be prevented from falling forward and interfering with the abutting draw-head by means ofa shoulder, h,

on the top of the pin, which rests on the drawliead. This shoulder, however, allows the pin to swing far enough forward so that it will retain itself in its reversed position. When the pin B is swung upwardly an ordinary straight round pin, F, can be droppedinto the forward ends of the slots 1) E, such slots being enlarged at those points for this purpose to form round holes G H, the other portions of the slots D E being of less width than the diameter of an ordinary round pin. The swinging pin B is likewise of less thickness than an ordinary pin. but itis of greater width, being made flat, and preferably of plate-steel.

Cars will be occasionally met with whose draw-heads have links so short that they will not couple with the swinging pin, by reason of its width. When suchis the ease the swinging pin is thrown up to the position shown in Fig. 3 and the ordinary pin is used. swinging pin is broken, an ordinary pin'can be used entirely until the draw-head is provided with a new swinging pin.

What I claim as my invention is-- 1. In a car-coupling, the combination, with 5 the draw-head A, having slots I) E, enlarged at their forward ends to form round holes G H,

and provided with lugsC forward of such slots,

of the broad flat swinging pin B, pivoted between the lugs C and offset to the rear at c, 9

and hanging vertically in the slots 1) E, such pin bearing against the forward ends, d 0, 0t said slots, and adapted to swing wholly out of the draw-head, to make room for an ordinary round pin, substantially as described and shown, for the purpose set forth;

2. In a oar-coupling, the combination, with the draw-head'A, having slots D E, enlarged at their forward ends to form round holes G H,

ofthe flat swinging pin B, pivoted to lugs C on the draw-head, and having shoulder h, substantially as and for the purpose set forth. IRVING W. KEITHLEY.
