CAR-COUPLING.

SPECIFICATION Aforming part of Letters Patent No.'517,059, dated March 27, 1894.'

Appnppnon ned september 19.1893. senti 110.485.862. (No modem To a/ZZ whom t may concern:

Beit known that l, CHARLES W. PATTON, a citizen of the United States, residing at Ohio Falls, in the county of Olark and State of Indiana, have invented a new and useful Oar- Coupling, of which the following is a specilication.

The invention relates to improvements in car couplings. The object of the present invention is to 1m prove the construction of car couplings,and to provide a simple and inexpensive device capable of holding a coupling pin elevated preparatory to coupling, and of maintaining a link in a horizontal position to enable the same to readily enter the mouth of the drawhead.

A further object of the invention is to enable a coupling pin to be readily lifted for setting preparatory to coupling from the top and sides of-a car, and to prevent any liability of the coupling pin being lifted too high and leaving the draw-head.

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

In the drawings-Figure lis a perspective View of a car coupling constructed in accordance with this invention and shown applied to a car. Fig. 2 is a central longitudinal sectional view showing the coupling pin supported preparatory to coupling. Fig. 3 is a similar view showing the link heldV in horizontal position preparatory to coupling. Fig. 4 is a detail perspective view of the combined link holder and pin support.

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

1 l designates a draw-head having a coupling pin perforation 2 to receive a coupling pin 3, and having mounted in its link cavity a combined pin support and link holder 4. The combined pin support and link holder consists of a plate, which is hinged by a pintle rod 5 at the top of the draw-head within the link opening or cavity thereof, and which inclines downward from front to rear and is depressed and held against upward swinging by a spiral spring 6 disposed on a pintle rod between eyes 7 of the plate and engaging the rearface of the latter. Atits center the combined pin support and link holder is provided with an opening 8 to permit the passage of the coupling pin to enablev the same to engage a link 9, as illustrated in Fig. 3 of the accompanying drawings, in which position the combined pin support and link holder engages the upper face of the link to hold the latter in a horizontal position to direct the same into the mouth of a draw-head. At the bottom of the opening is arranged an upward extending projection or lug 10, which is slightly transversely curved, and which is adapted toA be engaged by the, lower end of the coupling pin to hold the latter in an elevated position preparatory to coupling, as illustrated in Fig. 2 of the accompanying drawings; and when cars come together for coupling the link 9 will strike the combined pin support and link holder and withdraw the lug 10 from under the coupling pin to cause the latterto fall into engagement with it. The lower edge or portion adjacent to the edge of the combined pin support and link holder is bent slightly horizontally to enable it to engage the upper face of the link positively.

The coupling pin, which is provided at its upper end with an eye, is connected by a chain 1l with the upper end of a grooved segment 13, which is mounted upon a shaft l2, journaled transversely of a car 14:, and adapted to be turned from either side thereof for raising the couping pin for setting. The segment gives a direct upward pull to the coupling pin; it receives the links of a chain 11 in its grooves; and its ends are adapted to abut against the car to limit its swing. The upper end of the segment is adapted to strike the top of the car to limit its upward swing to prevent the coupling pin from being entirely withdrawn from the draw-head; and its lower end is adapted to rest against the car when it is swung down.

The rock-shaft l2 is provided at its ends y with handles 15, and one of its bearings 16 is provided with a notch 17 adapted to be engaged by the adjacent handle when the latter is in a horizontal position, whereby the coupling pin will be held elevated against coupling. The rock-shaft is capable of alim- IOO ited horizontal movement to enable its handie to engage lthe bearing 16. When the coupling pin is prevented from descending and coupling by reason of the handle of the rockshaft engaging the notch of the bearing, and 1t 1s desired to release the coupling pin from the top of the car, a chain 18 extends laterally and upwardly from the segment, and is adapted to be pulled to move the rock-shaft longitudinally sufficiently to disengage its handle from the bearing 16. The lower end of the chain 1S is secured to an eye 19, which 1s arranged on the segment intermediate of the ends thereof, in order that the chain 18, which extends to the top of the car, may be employed for lifting the coupling pin for setting, besides for disengaging the handle 15 from the bearing 16.

It will be seen that simple, inexpensive means are provided for supporting the coupling pin preparatory for coupling and for holding the link in a horizontal position, and that the coupling pin may be readily operated from the top and sides of a car.

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 construction.

1. In a car coupling, the combination of a draw-head having a coupling pin perforation, and a combined pin support and link holder arranged within the draw-head and hinged to the top thereof and inclining downward from front to rear and provided with an opening to receive a coupling pin and having adjacent to the opening a projecting support adapted to receive the lower end of a coupling pin, substantially as described.

2. In a car coupling, the combination of a draw-head provided with a coupling pin perforation, and a combined pin support and link holder arranged within the draw-head and inclining downward from front to rear and hinged to the top of the draw-head and provided with an opening to permit the passage of a coupling pin and having at the bottom of the opening an upward extending projection, which is transversely curved and which is adapted to receive the lower end of a coupling pin for supporting the same, substantially as described.

3. In a car coupling, the combination of a car, a draw-head having a coupling pin perforation, a coupling pin, a shaft journaled on the car and arranged horizontally and provided at its ends with handles and capable of alimited longitudinal movement, a bearing 16 receiving the rock-shaft and having a notch or shoulder to be engaged by one of the handles thereof, a segment mounted on the rock-shaft and connected with the coupling pin, and a chain extending upward and laterally from the segment to the top of the car to enable the segment to be swung upward and the shaft to be moved longitudinally, substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I have hereto axed my signature in the presence of two witnesses.

CHARLES W. PATTUN.
