CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 500,624, dated July 4, 1893.

Application filed March '7, 1893. Serial No. 464,957. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH L. SoWELL, a citizen of the United States, residing at- Althouse, in the county of Josephine and State of Oregon,have invented a new and useful Oar-Coupling, of which the following is a specification.

The invention relates to improvements in car couplings.

The object of the present invention is to simplify and improve the construction of car couplings, and to provide one which will couple automatically, and which may be readily uncoupled without going between cars.

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 isa perspective view of a car coupling constructed'in accordance with this invention. Fig. 2 is a central vertical sectional view. Fig. 3 is atransverse sectional view. I

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

1 designatesa draw-head provided in the bottom of its link cavity or opening with a longitudinal recess 2, and a vertical coupling pin perforation 3 at the rear terminus of the recess; a coupling pin lremains permanently in the perforation 3; and it has its upper end reduced and pivoted in a bifurcation 5 at the rear end of a link guiding plate 6, whereby the latter is hinged to the upper end of the coupling pin. The coupling pin has its lower end secured to the center of a transverse bar 7, which is arranged beneath the draw-head, audit is normally held elevatedin operative position by a weighted lever 8,fulcrumed on top of a car 9 and connected with the ends of the transverse bar 7 bya forked rod 10. The front end of the plate 6 is beveled and arranged at the front end of the recess 2; and when the pin is in its normal position the rear end of the plate 6 is raised to form an incline to enable a link, when cars come together for coupling, to slide readily up the plate and drop back of the coupling pin to couple the cars. By raising the inner end of the lever the coupling pin is lowered causing the plate 6 to be drawn into the recessand to have its upper face flush with the bottom of the opening or link cavity of the draw-head to release the link 11.

The inner end of the lever 8 is provided with a weight 12 which is sufficiently heavy to counterbalance the parts and to hold the coupling pin normally in an elevated position; and the weight slightly overbalances the coupling pin and its connection with the front end of the lever in order to require but little force to lift the rear end of the lever for uncoupling. The rod 10 is provided at its lower end with a fork having parallel sides 13, which are arranged in vertical grooves 14 in the sides of the draw-head for guiding the rod in its movement.

It will be seen that the car coupling is simple and inexpensive in construction, that it is efiective in operation and that it does not require a brakeman to go between cars either in coupling or uncoupling.

Any suitable provision may be made for uncoupling at the sides of a car; and I do sire it to be understood that 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.

What I claim is 1. In a car coupling, the combination of a draw-head provided in the bottom of its longitudinal opening with a coupling pin perforation, a coupling pin arranged in the perforation and extending above the bottom of the longitudinal opening of the draw-head, a weighted lever connected with the coupling pin and holding the latter normally elevated, and a link guiding plate arranged in the drawhead and having its rear end connected to the upper end of the coupling pin and its lower end arranged on the bottom of the longitudinal opening of the draw-head, substantially as and for the purpose described.

2. In a car coupling, the combination of a draw-head provided in the bottom of its longitudinal opening with a longitudinal recess and having a coupling pin perforation at the rear terminus of the recess, a coupling pin arranged in the perforation and projecting above the bottom of the opening of the drawhead, a link guiding plate having its front end arranged in said recess and its rear end hinged to the upper end of the coupling pin, a transverse bar connected to the lower end of the coupling pin and arranged beneath the draw-head, and a weighted lever connected with the transverse bar, substantially as described.

3. In a car coupling, the combination of a draw-head provided in its sides with vertical grooves and having a coupling pin perform tion, a coupling pin arranged in the perforation and extending above the bottom of the longitudinal opening of the draw-head, a link guiding plate having its rear end connected to the upper end of the coupling pin, atransverse bar connected to the lower end of the
