.To all whom t may concern.'

Be it known that I, GEORGE J ONNATHAN FORREY, a citizen of the United States, resid-` ing at Carlisle, in the county of Cumberland and State of Pennsylvania, have invented a new and useful Car-Coupling, of which the following is a specification.

The invention relates to improvements in car couplings.

The object of the present invention is to improve the construction of car couplings, and to provide a simple and efficient one, capable of coupling automatically and of ready uncoupling without necessitating going between cars.

A further object of the invention is to enable the link to be readily raised and lowered for guiding it into the mouth of the draw-head,I

without going between the cars and performing such guiding by hand.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective View of a car-coupling constructed in accordance with this invention and shown applied to a car. Fig. 2 is a reverse plan view. Fig. 3 is a longitudinal sectional view. Fig. 4 isa side elevation. Fig. 5 is a detail perspective View of the pinsupport. Fig. 6 is a similar view of the link-guider.

Like numerals of reference indicate corresponding parts in all the figures of the drawings.

1 designates a draw-head, having its drawbar 2 slidingly mounted between draft timbers 3, and connected'with a longitudinal rodV 4, which is slidingly mounted in a rectangular bearing box 5. The bearing box 5 is secured between the parallel draw timbers. It is provided at its ends with openings receiving the rod 4; and

spiral springs

6 and 7 are disposed on the rod and located respectively in ad- Vance and in rear of the bearing box or frame 5, whereby the draw-head is cushioned. The rear or inner end of the draft rod 4 is threaded to receive a nut 8, which secures a sleeve 9 on 5o the rear end of the draft rod 5 and disposed on the sleeve 9 is the spiral spring 7, which bears against the inner or rearend of the bearing box or frame and an annular flange of the sleeve 9. The longitudinal movement of the draw rod 4is limited bya sleeve 11, se- 55 cured to the rod 4 by a transverse fastening device 12, and arrranged within the rectangular bearing box or frame, and adapted to engage either end thereof.

The draw-head is provided with the usual 6o link opening, and has at its top a slot 13, communicating with the' same and receiving a swinging pin support 14, pivotally mounted in the draw-head by means of a transverse pin 15, and consisting of an L-shaped upper portion having an approximately horizontal arm, located above the draw-head, and operating as a weight to lhold a forwardly projecting supporting arm 15a in an approximately horizontal position for holding a coupling pin 7o 16 elevated preparatory to coupling. The coupling pin 16 is arranged in acoupling pin perforation; and thelink support is located in rear of the coupling pin, the transverse pivot pin being located adjacent to the angle of the L-shaped portion of the pin support. The lower portion of the pin support has hinged to it by a knuckle joint 17 a swinging bar 18, shoulders being formed at the back of the knuckle joint to prevent the bar 18 swinging 8o inward beyond an alignment with the lower portion of the pin support. The bar 18 is adapted to be engaged by a link 20, when the latter enters the draw-head for coupling, and

to be forced rearward by the link to carry the supporting arm 15 from beneath the coupling pin to cause the latter to fall and engage the link to effect the operation of coupling; but, when the coupling pin is raised to release ther link, the arm 18 is adapted to swing forward 9o to permit the link to be withdrawn from the draw-head. The weighted upper portion 2l of the pin support islocated adjacent tothe front of the car, and when 'the draw-head is moved inward in the operation of coupling incident to the cars contacting witheach other, the weighted arm 21 of the pin support comes in contact with the car whereby it is thrown forward to withdraw the supporting arm 15 j from beneath the coupling pin, to cause the roo same to fall and engage the link. By this construction the operation of coupling is rendered absolutely positive.

The link 2O is adapted to be raised and lowered to guide it into the mouth of a drawhead; and for this purpose a link guider is journaled in the draw-head at the bottom thereof. The link guider 22 is provided at opposite sides with laterally disposed journals, which are arranged in suitable bearing perforations of the sides of the draw-head. Its bottom 23 is curved; and the drawhead is provided in its bottom with a recess conforming to the conguration of the curved bottom of the link guider, in order to permit the latter to turn readily to raise and lower the outer end of the link. The link guider is provided with a longitudinal opening 24 to receive the coupling piu, and by means of which opening, the link guider may be readily manipulated and operated to raise and lower the link as desired, without the coupling pin interfering.

One of the journals of the link guider is extended through the draw-head, and has secured to it an arm 25, extending rearward from the journal and provided with an approXimately vertically disposed curved slot 26, receiving a stop pin or projection 27 to limit the swinging movement of the link guider. The slotted arm 25 is connected by a rod 2Sa with a forwardly or outwardly extending laterally oset arm 28 of a rock-shaft 30, which is journaled in a bearing plate 29 depending from the drawbar. The transverse rock-shaft extends through longitudinal slots 32 of depending plates or hangers 33, and are provided with weighted handles 34 adjustably secured to the ends of the shaft, and adapted to enable the link to be guided from either side of the car without going between the same. The depending plates or hangers 33 are bolted to the outer faces of the draw timbers, and the rectangular bearing frame 5 is rigidly secured between the said timbers by horizontal bolts.

It will be apparent that the car coupling is positive and reliable in operation, that it is capable of automatic coupling, and that the link may be guided at either side of the car without going between cars.

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
