IMPROVEMENT IN CAR-COUPLINGS.
Specification forming part of Letters Patent No. 127,790, dated June 11, 1872.
Specification describing a new and useful Improvement in Oar-Coupling, invented by SAMUEL G. NORTHROP, of Wilmington, in the county of New Hanover and State of North Carolina. a
Figure 1 is a detail longitudinal section of my improved car-coupling, coupled. Fig. 2 is a front view of one part of the same.

My invention has for its object to furnish an improved car-coupling simple in construction and effective in operation, and which may be readily adjusted to couple itself when the cars are run together; and it consists in the construction and combination of various parts of the coupling, as hereinafter more fully described.' v v A and B represent the bumper-heads of two adjacent cars, which are connected with the the bumper-heads are made large, and are divided into two compartments by horizontal partitions a N. G are the coupling-pins, which pass down through the bumper-heads A B, and through the coupling-link or bar D, which enters the lower compartments of the bumperheads A B. One end of the link or bar D is made thick, so as to hold the link in a horizontal position to enter the bumper-head of the adjacent car when the cars are run to-' gether. The thinner end of the link D has a slot formed through it to receive the couplingpin to give the necessary play to the coupling. In each partition a N, at the rear side of the hole through which the coupling-pin passes, is formed a recess, a 11 to receive the lower end The cavities of v of the coupling-pin'C to hold it suspended while the cars are being run together. The recesses a? b not only support the pins, but
support them with their lower ends below the upper surface of the partitions a D so that the said coupling-pin may be sure to drop into its hole when pushed out of its recess, in the manner hereinafter described. E are the levers, which are pivoted to the sides of the bumper-heads A B at the rear edge of the horizontal partitions a N. The upper ends of the levers E are bent forward, so as to touch or nearly touch the coupling-pins 0 when in position to couple the cars. When the lower end of the coupling-pin O is placed in the recess a or b, it pushes the upper end of the lever E back, which swings the lower end of said lever forward. As the cars are run together the forward end of the coupling-link D strikes the forwardly-projecting lower end of the lever E and pushes it back. This swings the upper end of said lever E forward, and
pushes the coupling-pin C out of the recess a SAMUEL GROVES NORTHROP. Witnesses:
