CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 267,621, dated November 14, 1882.

- Application filed July 31,1882. (No model.)

To all whom it may concern:

Be it known that 1, JAMES A. WALKER,a citizen of the United S tates,-residing at Gales- Y burg, in thecounty of Knox and State of Illinois, have invented certain new and useful Improvements in Car-Couplin gs; and I. do hereby 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 ap- IO pertains to make and use the same.

This invention relates to railway-oar couplings; and it consists in combinations and constructions hereinafter described, and set forth in the claims hereto annexed.

In the accompanying drawings, which illustrate my invention, Figure 1 is a top plan. Fig. 2 is also a top plan, with the parts in different relative positions from that shown in Fig. 1; Fig. 3, a plan seen from below; Fig. 4, an enlarged sectional elevation in line a: m in Fig. 1; Fig. 5, a detail-a side elevation of the draw-head alone. Fig. 6 is a perspective of the draw-head alone.

Referring to the drawings by letters, the same letter indicating the same part in the different figures, letter A represents a portion of the bottom of a car, which may be of any desired construction, with a central recess, a, and

side portions or bumpers, a, which project forward of the rear wall, a, of the recess a. The wall a should preferably be in about same vertical plane as the front end, a, of the car.

B is the draw-head, which may be attached to the car in any ordinary or desired manner, with its forward end in about the same vertical plane as the forward ends of the bumpers a. The forward end of the draw-head is enlarged laterally, and each side of the enlarged portion is formed as shown-that is, convex in 0 its longitudinal horizontal section and also convex in its transverse section-and preferably with its lower side somewhat narrower than its upper side.

i U G arejaws pivoted one to each side of the 5 draw-head B by a bolt, 1), which passes horizontally through a slot, 0, in each jaw, and

through a hole in the draw-head. The side of each jaw O O is concave where it rests against the adjacent side of the draw-head. The jaw 0 is dart-shaped at its forward end,,and the jaw C has a hook or shouldered catch, 0, on

its forward end and side, confronting the jaw C. When thejaws G G are drawn forward, as permitted by their slots moving on the bolt D, their curved sides at 0 will be forced into con- 5 tact with the rear portions respectively of the convexed sides of the draw-head by means of the outer sides of-the jaws O 0 coming in contact with the pins d in the bolt D, and the front ends of the jaws be thereby forced over and held near to each other, as shown at Fig.

1. When the jaws 0O are pushed backward,

as shown by full lines at Fig. 2, the rear ends of said jaws will be free from the draw-head,

so as to permit separating the front ends of 6 thejaws, as shown by dotted lines at Fig. 2.

In addition to the movements of thejaws O O, hereinbefore described, they may also be swung or turned upwardly on the bolt D as a' fulcrum, as shown by dotted lines at Fig. 4.. In turning thejaws downwardly from the position last described the springs e-one between the rear end of each jaw and the draw-headwill force the rear ends of thejaws outwardly and their forward ends toward each other.

F is a rod or shaft extending transversely across the bottom of the car, and is journaled in suitable bearings,f, so that it can be rocked or oscillated on its longitudinal axis by a crank, f, at either or both of its ends. An arm, 9,

extends forwardly from the shaft F over each jaw G O, and by turning the crankf forwardly these arms will force said jaws downwardly and into their horizontal positions, asshown by full lines at Fig. 4. Arms g project rearwardly from the shaft F and act upon the rear ends of thejaws G U, and thereby turn or swing the jaws O C upwardly, as shown by dotted lines at Fig. 4, when the crank f is turned in an opposite direction to that last described. The movements of the jaws O U downwardly at their forward ends are limited by their rear ends coming in contact with the shaft F, and their upward movements are limited by their forward ends coming in contact with the rear 5 wall of the recess a or the arms g, which come between the jaws and said wall. -Any suitable stop or catch may be placed on the shaft F to retain the jaws O O in their elevated positions. When the jaws U 0 are in their horizontal por00 sitions they will couple two cars when brought together, as shown at Fig. 1, and when draftpower is applied to either car it will draw the jaws outwardly lengthwise and tighten and secure the couplings, as hereinbefore described.

The shaft F may be turned to swing thejaws O O upwardly on either car, as hereinbefore described, to uncouple the cars. In coupling, the jaws will be forced rearwardly,so they may separate at their forward ends, and the springs e will hold them sufficiently to prevent uncoupling until thejaws are drawn outwardly by the movementof the cars, and the coupling thereby securely fixed, as hereinbefore described.

It will be seen that in case either car should leave'the track, should fall through a bridge, or be thrown from the track and turn over, the couplings will at once be separated. By nsingjaws G C of considerable thickness vertically they are adapted to couple cars of different heights.

The shaft F may be made to operate the jaws O O in a difi'e'rent manner from what I have shown, and may be operated from a rod extending to the top of the car.

Each draw-head is constructed with a recess in its front end, similar to the ordinary drawhead,whereby an ordinarylink and pin,h, may be used to effect a coupling, when desired, by simply turning the jaws 0 G into their vertical positions and out of the way.

In coupling, the bumpers a will come in contact and prevent injury to other parts, and these bumpers may be constructed as shown, or they may be formed of projecting springbars or spring-bumpers.

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

1. In a car-coupling, in combination with draw head or bar, jaws pivoted to said drawbar, whereby they may swing both outwardly and upwardly at their forward ends, substantially as and for the purpose specified.

2. In a car-coupling, in combination with the draw-bar, coupling-jaws adapted to couple at their front ends and to swing outwardly and upwardly, substantially as and-for the purpose specified.

3. In a car-coupling, in combination with the draw-bar, coupling-jaws adapted to couple at their front ends, substantially as described, and to swing upwardly, for the purpose specified.

4. In acar-coupling, in combination with a draw-head, the jaws O O, constructed at their forward ends as described, and slotted where they are pivoted to the draw-head, substantially as and for the purpose specified.

5. In a car-coupling, in combination with a draw-head having an enlarged front end,with sides constructed substantially as described, slotted jaws O 0, adapted to slide forward on their pivot to said draw-head for the purpose of securing themin place, and to slide rearward for releasing them, substantially as and for the purpose specified.

6. In a car-coupling,in combination with the draw-head, slotted jaws pivoted thereto, as described, springs e, arranged to operate therewith, substantially as and for the purpose specified.

7. In a car-coupling, in combination with jaws adapted to swing substantially as described, a rocking shaft adapted to swing the jaws in vertical planes, substantially as and for the purpose specified.

' 8. In a car-coupling, in combination with draw-bar B and swinging jaws O O,-a rocksh aft, F, adapted to operate said swin gin g jaws, substantially as and for the purpose specified.

In testimony whereofl affix my signature in presence of two witnesses.
