SPECIFICATION formingpart of Letters Patent No. 746,730,dated December' 15, 1903. Application nea my 2a,19os.1 sean No. 167.293. mo man;

To LZ whom il? may concern,.-

Be it known that I, SAMUEL MORRIS, a citizen of the United States, residing at Newark, in the county of Licking and State of Ohio,

`5 have invented certain ne'wvand useful Improvementsin Car-Couplings; and I do hercby 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 io appertains to make and use the same.

The object of this invention is to provide a carwcoupling of simple and improved construction in which the coupling may be automatic, and which may be quickly and easily manipulated to prepare for uncoupling.

zo a horizontal sectional view of the draw bar and head, showing the knuckle and knucklelocking parts in plan and in locked position.

Fig. 2 shows the same sort of vieW,'eXcept that the knuckle and knuckle-locking parts are in uncoupled position. .Fig.'3 is a vertical sectional-view taken on the plane a; as,`

Fig'. l, looking in the direction indicated by the arrow, the knuckle-lock being in lockedv Fig. 4 is a similar view to that ofV position.

that the lock is shown to be raised. Fig. 5 is a perspective view of the knuckle.

Like characters of reference rin the several views designate corresponding parts.

l designates the draw-bar, and 2 the knuckle. The knuckleis pivoted on` a pin 2f in the draw-head, as usual. The knuckle has the usual outer coupling portion or jaw and an inner arm 2ad with a beveled upper side 2b,

4o adapted to pass under the knuckle-lock, as

hereinafter described, a dat-ended lock-en-`l gaging toe 2, andahook-shaped heel 2d. The draw-head has an appropriate cavity to contain the knuckle-lock and knuckle-lock-oper- The cavity also has an inward projection liL back of the pivot 2f to be engaged by the heel 2d on the knuckle-arm 2a when the cars are coupled.

3 designates the dog or lock for locking the This is pivoted at 3a in the rear of the cavity of the draw-head, so as to beV capable of oscillating in a vertical plane or at right angles to and intersecting the plane in which the arm 2a of the knuckle oscillates. The rear portion of the knuckle-lock is formed into an angularly-projecting toe 3, having its upper edge beveled toward the lever fl, as indicated at 3C. l

4 designates the lock operating device. This consists of a small horizontally-swinging lever having for its fulcrurn a vertically-l standing cran k-shaft ai, the upper or cranked end of which is above the top of the drawhead. The shaft 4a can be rocked by means of a rod (not shown) extending to the side of the carer by any other appropriate device accessible to the trainman.

When the cars are coupled, the parts stand approximately as seen in Fig. l. When it is desired that the cars be uncoupled, the lever 4 is turned so that the inner arm thereof strikes the toe 3b and lifts the dog, as seen in Fig. 4, after which the arm 2a is free to move outward. When the a`rm 2ab is turned out by the action of the outer end of the lever 4 on the leg 2a, thel dog is supported on the inclined surface 2b, and because this inclined surface 2b tends upwardV the dog is lifted and the angularlyprojecting toe 3* depressed, thus permitting the inner arm of the lever to be turned outward to lie Within the angular space between the dog 3 and toe 3b, as seen in Fig. 3, and therefore in position to lift the dog when it is again desired to uncouple coupled cars,

f When the coupling is to be set to open position preparatory to coupling, as seen in Fig. 2, the Vouter arm of the lever l can be turned tobearnpon or .strike the inner side of the arm 2=ito move said arm as far outward as the circumstances may require.

` The .inclined or beveled portion 3c of the toe 3b permits the leverlt to ride over the toe into the angular space between the toe and the dog should it happen that the dog is left low down on the incline 2b.

The invention'is susceptible of' modifica tion. For example, instead of resting on the inclined portion 2b in the opening position4 of the coupling the dog 3 can be held up by the lever 4.

- If the pin 2f should be lost or cut off by an ICO extraordinary load, the cars will still remain coupled because of the engagement of the heel 2d with the projection la.

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

l. In a car-coupling, the combination of the knuckle having a horizontally-swinging arm with a lockinglend thereon, a verticallyrocking lever or dog adapted to engage the locking end of the knuckle-arm and having an angularly-projecting toe 3b, a horizontal rocking lever unattached to said dog, adapted to act on said toe to operate it and pass over the same 1 2. In a car-coupling, the combination of the knuckle having a horizontally-swinging SAMUEL MORRIS.
