MAHLON IVELLS, OF IIAUGIIVILLE, INDIANA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 554,610, dated February 1 1, 1896. Application tiled July 8, 1895. Serial N- 555,1S9. (No model.)

To all whom t may concern:

Be it known that I, MAHLON VELLS, a citizen of the United States, residing at Haughville, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Car-Couplings; and I do 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 appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to a device for connectin g railroad-cars together in a train; and it consists of a new and novel coupling to be attached to an end of a car in the usual manner, and by which the car may be automatically coupled to another car having a like coupler or an ordinary link-and-pin draw-bar,

and will be more full described hereinafter.

My object is to provide a cheap and reliable automatic coupling that may be used in connection with any other form of coupling as well as with those like itself, and with this end in view I have constructed a coupling that is cheaply constructed, of few parts, economical and durable in use.

Referring to the drawings, Figure l represents a longitudinal side view; Fig. 2, an end view; Fig. 3, a longitudinal View, half-plan of top and half-sectional through center; and Fig. 4 is a longitudinal vertical sectional View through center.

The draw-head D is a casting of common iron, steel, or malleable iron, having an open mouth d for the reception of the coupling-bar C. Suitable openings are cored in the head, into which the coupling-hooks A A are secured; also holes into which the bolts e and 71, are inserted. A suitable hole is also cored into the bottom of head for the reception of the uncoupling-pin n, and a hole Z in bottom and a like hole 7o in upper lip B is provided to receive a coupling-pin when an ordinary coupling-link is used in connection with link-and-pin coupling. The upper lip or top I3 is a casting of iron or steel and is secured in its place to form the top wall of drawhead by the hinge-bolt h passing through a hole near its rear end, while its forward end rests upon shoulders in the mouth to keep it in a horizontal position, yet permitting the forward end to be raised when desired. A leaf or plate spring g is attached by a screw-bolt 0 at one of its ends to the rear top part of the draw-head D, while its other end presses upon the top of lip B, holding it normally in place, but yielding sufficiently to allow the lip to be raised.

- The coupling-hooks A A are secured in the side recesses of the head D by bolts e passing through holes near and back of the center of each hook-bar, respectively. At the rear end of the hook-bars a coiled spring f is intervposed between them, pressing the ends apart so that, the hook-bars being pivoted near theirV center, their opposite ends consequently are normally held toward each other. Shoulders j are provided at forward end of recesses, against which the end of hook-bars come in contact when under the strain of pulling, instead of straining the pivot-bolts e, thus obviating the danger of bending the bolts.

The couplingbar has at each end an arrowhead forming on the sides the lugs b b', and also a hole 'L' to receive a coupling-pin when it is used in connection with ya linkandpin draw-head. At each side of the forward end of draw-head suitable ears fr are attached by means of screw-bolts, and to these the uncoupling-levers p are attached by means of the loose pins S. The upper ends of levers p are connected by rods t, which extend to each side of a car, respectively, so that a car may be uncoupled from another from either side of the track without requiring a man to go between the cars. The uncoupling-pin n having the yoke m rests upon the lower ends of the two levers p and is in a normal position when down, as shown in Figs. 1 and 2.

In practical operation the draw-head D, having the usual shank at its rear, is secured to one end of a car in the usual manner. The coupling-bar C enters the mouth d. The point c comes in contact with the beveled points of hooks a a' and forces them apart, as shown at a', Fig. 3, and when the point b has passed the point a the hooks close together and engage the lugs Z2 b, performing the act of coupling, the end c being held in the draw-head of an adjacent car. lTo uncouple the two cars, one of the rods tis drawn IOO toward the side of car, which action forces upward the pin n against the under side of bar C, which in turn raises the upper movable lip l, permitting the lugs on side ,of bar C to rise above the hooks u cb', when the bar G may be Withdrawn by the opposing car or by hand, if desired, thus completing the act of uncoupling.

Having; described my invention, what I claim as being' new and novel, and desire to secure by Letters Patent, is-

ll. In a car-coupling the combination of the ccmplingdiooks A, A with the pivotpins e, e and coiled spring f; the movable lip or top l5 with pivot-pin h; the spring g; the lugs ff', r; the levers p, p o'i' bell-crank forni having pivotal pins S, S; the uncoupling-pin n havin g the yoke Im, and the coupling-bar C having pin-holes -i substantially as and for the purpose shown and described.

f2. The combination, in a car-coupling, of the ci'iuplng-hooks A, A, having` the shoulder at forward end bearing at j; the hooks CL a', the shoulder j in the side opening of draw-head D; the arrow-head conplingbar C having the pin-hole 1', i', the hinged top B of dranhead; the spring f; the nnconpling-pin n having the yoke m; the levers p, 19, and the ings fr fr, substantially as and for the purpose shown and described.

3. In a car-coupling,having conplin g-hooks, the combination of the shoulder j in recess or' head; the shoulder at end of hook-bar cen"- forining to shoulder-j in head; the hinged top B of draw-head; the spring; g; the uncoupling-pin n having the yoke m, and the levers p, p attached to lugs r, o', substantially as and for the purpose shown and described.

In testi lnony whereof I afix my signature in presence oi' two witnesses.
