CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 447,718, dated March 3, 1891.

Application filed October 13, 1890- To aZZ whom it may concern.-

Be itknown that we, PEDER PEDERSEN and DEWITT C. MILLER, citizens of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented a new and useful Improvement in Oar-Couplings, of which the following is a specifica- This invention has relation to new and useful improvements in self-coupling car-couplings.

The object of this invention is to provide a simple self-acting car-coupling that may be attached to any car now in use, and be so constructed that it may be used with the ordinary link and pin; and in furtherance of this object the invention consists in the construction, combination, and arrangement of and finally pointed out in the claims.

Figure 1 in the annexed drawings shows a top View of my improved coupling. Fig. 2 shows a sectional elevation thereof. Fig. 3 illustrates a transverse sectional view thereof. Fig. at shows a sectional view of the sliding connecting-link, and- Fig. 5 shows a top View of the coupling-link.

Similar letters of reference refer to corresponding. parts.

A in the drawings shows a draw-head of the usual form of construction, which is provided with a suitable chamber. lVithin this chamber is provided with two pivoted jaws, (marked 13 B,) which are precisely alike in construction and pivoted at a suitable point within said chamber, as shown in Fig. 4. These jaws are so formed attheir gripping ends snugly hug and accommodate a duplex spearshaped link 0, as shown. These jaws are held within the draw-head by means of suitable bolts C O, which pass entirely through the draw-head, and thus pivotally hold the jaws within the head. The jaws are further provided with two shoulders surrounding the bolts, upon which said jaws ride, as shown in Fig. 2. The stem or rear part of the jaws is but half the thickness of the jaws proper, so that one stem may ride upon the other. These stems are further provided with suitable slots,

which are adapted to accommodate a pin D,

and working within suitable bearings of the bifurcated actuating-lever H, as illustrated in Figs. 1 and 2.

The actuating-lever H, which is of metal, is provided with suitable bearings adapted to contain the bolt K and upon which it has pivotal movement. The jaws B B are actuated by means of this lever, which may be worked from the deck of the car by means of a chain and brake-wheel, or below by means of a hand-lever, as shown in the figures.

\Vithin the chamber of the draw-head A and upon each side thereof are affixed the bow-springs L L, which work against the jaws B B and tend to keep them in a locked position.

The pin D, which rests within the sliding links E E, and the slotted stems of the jaws B B, is further guided and works within two longitudinal slots within the top and bottom portions of the draw-head, as will be understood by referring to Fig. 4.

The operation of our device is very simple. YVhen a coupling is to be made, the operatinglever H is forced toward the dead-wood, and being pivoted near the center the curved arms are carried forward, and they being provided with the slotted bearings containing the lug e of the slidinglinks E carry said links forward within their guideways, and these two links being connected by means of the pin D in turn carry that pin forward within its guideslot. Now, as this pin rests within the slotted stems of the jaws B B and has a fixed direction, it will be readily understood by all those conversant with the art to which this invention relates that the forward or gripping ends of the jaws B B will be carried readily outward as the pin D moves forward within ICO the stems, thus forcing them into an open position. The lever II may be locked in its extreme position and so keep the jaws open. However, when two cars are to be coupled, it is simply necessary to fiXthe coupling 0 within one of the draw-heads and then let the cars bunt, which will force the spear-head of the pin within the jaws, the springs L L of which readily give way, and thus permit the entering of the pin independent of the lever II.

By the peculiar construction of the jaws B B the cars maybe uncoupled while in motion, as the jaws are so pivoted that while operatin g they work away from the pin. At the rear the coupling is further provided with a butter-stein M, which is keyed to the drawhead in the manner shown and provided with a suitable coiled spring which works against the draw-head and stem M, and at the other end against a follower N, which works upon the reach -rods P P, as is usual in car construction of this class. The coupling-pin employed is a double-ended spear-head link, as is clearly shown in Fig. 5.

\Vhen it is desired to use the ordinary link and pin in connection with one coupler, it is simply necessary to lock the jaws in their open position, when a link and pin may be used, a hole adapted to contain the latterbeing provided for that purpose. I

The device is exceedingly simple and may be attached to any car now using the ordinary link and pin.

Having thus described our said invention,

what we claim as new, and desire to secure by United States Letters Ilfatent, is

1. In a car-coupling, the combinatiomwith a recessed draw-head, of two pivoted jaws within said recess, a pin working within the slotted stems of said jaws, sliding links connected to said pin, an operatinglever connected to said sliding" links, and a doubleheaded spear-shaped link, all arranged substantially as and for the purpose set forth.

2. In a car-coupler, the combination, with a recessed draw-head, of two pivoted springactuated locking-levers A, pin and links connecting said levers to a suitable operatinglever, a double-ended spear-ended connectingpin adapted to work between said jaws, and a buffer-stem keyed to said draw-head, pro vided with a spring, all arranged substantially as described.

3. In a car-coupler, the recessed draw-head A, the pivoted spring-actuated jaws 13 B, the pin 1), link E, lever II, and the bufferstein M, in combination with the pin C, all' arranged and adapted to operate'substantially as described.

In testimony whereof we aflix our signatures in the presence of witnesses.
