CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 459,177, dated September 8, 1891.

Application filed March 23, 1891- Serial No. 386,0094 (No model.)

enable others skilled in the art to which it ap I pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention is a car-coupling; and my said invention consists in certain details of construction of the parts composing the same whereby a simple, practical, and durable carcoupling is produced that is easy of operation and automatic in action, and in carrying out my invention I proceed as follows, reference being had to the accompanying drawings, forming a part thereof, wherein- Figure l. is a view in perspective of a carcoupling constructed according to my invention, the movable jaw that effects the coupling being shown as in its elevated position. Fig. 2 is a detailed view in perspective of the stationary member of the coupling in illustration of the construction of the same and Fig. 3 is a similar view of the movable member.

This coupling is designed as an improvement upon the car-coupling for which Letters Patent of the'llnited States were granted to me on October 14, 1890, No. 438,372, and it is composed of a stationary member A, secured to the bed-frame of the carin the usual or any desired manner, having a iaring mouth A,whose outer edge is made curved to allow for play between the draw-heads of opposing cars in going around curves and the rear of which mouth terminates in a recess a, having an overhanging front edge a', for the purpose as will presently appear, and through the bot tom of which mouth is a slot a2 to receive the tooth of the movable jaw. .lust behind the draw-head and upon opposite sides thereof is formed a recess or socket a3, having a curved front edge, as at a4, and transversely through the draw-head centrally of these sockets is a hole a5. Such constitute the stationary mema ber of the coupling, united to which is the movable or hinged jaw B, which said jaw has at its front central portion a tooth b, whose front edge tapers toward the lower end and is received into the opening a2 when effecting a coupling, and upon each side of the rear extremity of which movable jaw is formed integral therewith lugs or ears d d, which fit the recess or sockets a3 upon each side of the part A of the draw-head, and are secured in position by a pin C, that passes through the said ears b b and the hole a5 of the part A. As will be noted, the ears b b of the hinged jaw B straddle the member A and are rounded, the curved front edge of which, when the jaw B is down and the car coupled, comes flush against the correspondiugly-curved shoulders a4 of the sockets a3, while the pivot-hole c through said ears D for the pivot-pin O is near the lower edge and near the rear edge of said ears, so that the line of draft through the draw-head is below the center line thereof, and because of said pivot being at the rear edge of the jaw the entire gravity of the jaw when raised to its full extent is forward of the pivot-pin.

To prevent the too far vertical movement of the jaw B, a shoulder D is provided, against which the rear end of said jaw B will impinge when elevated, and such stop D is so arranged that the jaw B cannot be raised to a position at right vangles to the part A.

To provide for the lifting of the jaw B from either the top or sides of the car through suitable connection, an eye d is provided. l

When desired to effect a coupling, the link E, which is of the usual construction,is placed in the mouth of the draw-head and rests beA neath the overhanging front edge a of the recess a, and is so held in a proper horizontal position to enter the mouth of the approaching draw-head. The link, coming against the beveled front edge of the tooth l), lifts the jaw B, and passing behind the said tooth the jaw B drops of its own gravity and automatically effects the coupling of the cars together. No going between the cars to direct the link is therefore necessary in this case, and to uncouple the cars the jaw B is simply lifted by any proper means.

Owing to the front edge of the ears b b of TOO the jaw B, as before stated, impinging against shoulders on the draw-head, all strain is removed from the pivot-pin, and as thefrout edge of the tooth Z) also impinges against the front edge of the socket a2 when said jaw is in its closed position a point of bearing for the strain ofwdraft is also located at this point, so that the draft of the link will be exerted upon the tooth of the movable jaw and said tooth against the front edge ot' its socket upon the pivot-pin and the curved shoulders of the draw-head and ears, making four separate points of bearing, so that the pivot may be made light, and danger of breakage is not likely to occur, and durability is insured.

Aside from the cap but three pieces'constitute the coupling the stationary jaw, theV movable jaw, (each of which may be cast and requires little itting,)and the pivot-pin-so that a cheap and strong coupling is produced. As the hinged jaw straddles the stationary jaw, should the pivot-pin break the parts will not become detached.

To prevent the entrance of snow or ice or the lodgnient ot' dirt between the jaws of the coupling, a cap or shield, as at S, is provided,

that is attached tothe rear top edge of the jaw A and covers the hinge-opening between the members of the draw-head. This shield maybe of sheet metahlcather, rubber, or any other suitable material and attached to either jaw.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent of the United States- In a car-coupling, in combination, the stationary member A, having curved -laring mouth with recess a, having overhanging edge a', slotaz, sockets a3 d3 at each side,with curved shoulders a4, hole a5, and shoulder D,forrning a single casting, and movable jaw B, forming the upper half of the draw-h ead', with tapered tooth b and curved ears b b at each side of its rear end, forming a single casting, and pin C for uniting the two members together, as described and shown, for the purposes specified.
