CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 643,145, dated. February 13, 1900.

Application led April 17,1899.

To @ZZ whom, it may concern:

Be it known that I, ANTHONY S. MARTIN, a citizen of the United States, residing at Maiden, in the county of Catawba and State of North Carolina, have invented a new and useful Car-Ooupling, 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 comparatively inexpensive one capable ot' coupling automatically and adapted to be readily uncoupled from the tops and sides of ears without going between them.

The invention consists in the construction and novel combination and arrangement of parts hereinafter1 fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a car-coupling constructed in accordance with this invention and shown applied to a car. Fig. 2 is a longitudinal sectional view showing two cars coupled. Fig. 3 is a transverse sectional View. Fig. 4 is aldetail perspective view of the link. Fig. 5 is a detail perspective view of the lever for engaging the arm of the arrow-headed link.

Like numerals of reference designate corresponding parts in all the iigures of the drawings.

l designates a draw-head open at the top and composed of vertical sides and a horizontal bottom, and pivoted between the sides is a substantially horizontal arrow-headed link 2, mounted on a transverse pin 3 and having its engaging shoulders or hooks at its top and bottom and adapted to interlock with a corresponding arrow-headed link, as illustrated in Fig. 2 0f the accompanying drawings. The arrow-headed links, which present pointed or tapered outer portions, are adapted to engage each other automatically, and either link may be arranged at the top or bottom.

The arrow-headed link is supported by a coiled spring 4,arranged within the draw-head and interposed between the bottom of the same and the shank of the link and secured to both of said parts, as clearly illustrated in Fig. 3 of the accompanying drawings. The link Serial 110.713,408. (No modela.

and the draw-head are provided with studs or projections fitting within the ends of the extending upward and inward from the link` and havin gits upper or rear end located above the draw-head and adapted to be engaged by a depressible lever 6, arranged in a substantially horizontal plane and fulcrumed at its rear end on a post or support 7 of the drawhead. The lever 6, which engages the arm 5 at a point between its ends, projects outward beyond the upper end of the arm 5, and its outer end, which is curved upward slightly, is adapted to be engaged by devices for lifting the arrow-headed link out of engagement and effecting the operation of uncoupling.

The depressible lever is operated from the top of the car, as illustrated in Fig. l of the accompanying drawings, by a vertically-movable rod `8, mounted in suitable guides V9 of a car l0 and extending from the depressible lever to the top of the car. By this construction the operation of uncoupling may be performed from the tops of cars without leaving the same and by simply depressing the lever which is connected with the upper link of each pair.

The operation of uncoupling may be performed from the sides of cars by inner and outer levers ll and l2, fulcrumed between their ends and arranged as shown in Fig. l. The inner end ot' the inner lever is located above the depressible lever, and its outer end is weighted for holding its inner end normally above and out of engagement with the depressible lever. The outer lever l2 is provided at its outer end with a handle, and its inner end is located beneath the adjacent end of the inner lever, and when the handle portion of the outer lever is depressed the link will be raised. The arms of the inner lever 1l are arranged at a slight angle to each other and extend upward, and the arms of the outer lever are disposed at a slight angle and ex- IOO 'tend in the opposite direction at the pivot,

the outer arm of the outer lever being curved and having its outer portion extending up- Ward. The arrangement of levers shown in Fig. l is designed for box-cars, and when the car-coupling is employed on flat-cars a single lever may be used.

The draw-head is provided at its front end with a horizontal slot 13 and has perforated ears arranged in pairs and extending out horizontally from bothA sides of the draw-head above and below the slot. The slot and the perforated ears enable the draw-head to couple with an ordinary pin-and-link car-coupling, and in the event ofthe breakage of any of the parts of a coupling two cars may be coupled with an ordinary link.

The invention has the following advantages: The car-coupling, which is simple and comparativelyinexpensive in construction, is positive, reliable, and automatic in its operation, and it may be readily coupled and uncoupled from the tops and sides of cars without going between them. It is adapted to couple with an ordinary pin-and-link coupling, andin the event of the breakage of any of the parts an ordinary link can be used.

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

What I claim isl. In a car-coupling, the combination of a draw-head, a link pivoted within the drawhead and arranged to swing vertically, an arm extending rearward from the link beyond the pivotal point thereof and projecting above the draw-head, a post or support carried by the draw-head, a horizontal lever 6 fulcrumed at its rear end on the post or support and engaging the arm of the link and extending forward beyond the car, and operating mechanism mounted on the car and arranged to engage the lever 6, substantially as described.

2. In a car-coupling, the combination with a car, of a draw-head, a horizontal link pivotally mounted Within the draw-head and arranged to swing vertically, and provided With a rearwardly-extending arm projecting above the draw-head, a horizontal lever 6 fulcrumed at its inner end and engaging the arm of the link and extending beyond the car, a vertically-movable rod mounted in suitable guides of the car and having its lower end arranged to engage the lever 6, said rod having its upper end arranged at the top of the car in position to be depressed by the foot, and means for depressing the lever 6 from the side of the car, substantially as described.

3. In-a car-coupling, the `combination with a car, of a draw-head, a link pivotally mounted in the draw-head, arranged to swing vertically and provided with an arm extending above the draw-head, a depressible lever 6 fulcru med on the draw-head and engaging the arm of the link and projecting beyond the car, the inner lever 1l fulcrumed on the car and having one arm arranged to engage the depressible lever and having its other arm weighted, and the outer lever 12 fulcrumed between its ends and extending to the side of the car, its inner end being arranged beneath the Weighted end of the lever 1l, substantially as described.

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

ANTHONY S. MARTIN.
