IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 60,025, dated February 23, 1875; application filed August 25, 1874.

To all whom it may concern:

Be it known that I, HORACE MERIAM, of Berlin, in the county of Green Lake and State of Wisconsin, have invented certain Improvements in Oar-Couplings, of which the following is a specification:

The nature of my invention relates to a coupling which is designed for railroad-cars; and the object is to couple cars when they come together, connecting them securely, and

' allowing sufficient play for them to run when so coupled; also, to disconnect or uncouple them, when desired, without the necessity of the operator going between the cars for that purpose.

my invention consists in a peculiarly-00m structed oscillatingelbow, which automatically uncouples the cars, being operated by a lever, which will be hereinafter set forth. It further consists in an oscillating lever adapted to al low the cars to couple automatically and lock them in that position; also, to uncouple without getting between the cars.

In the accompanying drawings, which form a part of this specification, Figure 1 is a vertical sectional view of my improved coupler. Fig. 2 is the same as Fig. 1, showing my invention uncoupled. Fig. 3 is a horizontal sectional view of the same.

Referring to the drawings, A is the body or frame which holds the operating parts, to be described hereafter 5 and B, the same on the other to be coupled. Situated vithin this frame A is an inclined plane,D,against which the connecting-link strikes in the act of coupling. The back surface of this piece D is vertical, and the whole is adapted so as to allow the link to pass over it on every side. 0 is an armed lever, pivoted in the frame at c, the arm 0 thereof being provided with a means for raising the same from the platform of the car at the will of the operator. It may also be provided with a slide or spring catch to prevent the same from being raised by the jar of the car. The vertical arm 0 extends (l0W11- ward and reaches down below the vertical back surface of the piece I). F is an elbow having two arms arranged at nearly right angles with each other, and it is pivoted at f to the frame. The arm G of the elbow F is bifurcated, and the bifurcated extremities pass one on each side of the piece D. H is the coupling-link.

The operation is as follows: The link H, when the cars come together. strikes the inclined plane of the piece D and passes along the same until it strikes the arm 0 of the oscillatng lever O. This action raises the arm 0 until the link, by gravity, drops around the piece D, and the lever O, by gravity, resumes its original position. The lower surface of the arm 0 passes over the link, thus locking the ears together.

In uncoupling the cars it is only necessary to raise the arm 0 of the lever C. The arm presses against the elbow F, which, turning backward on its pivot f, raises the arm Gr, bearing up the link H over the piece D, and the cars are disconnected.

I claim 1. The elbow F, with bifurcated arm G, in combination with lever O and link H, as shown and specified.

2. The combination of the lever G, elbow F, having bifurcated arm Gr, link H, and piece D, as shown and specified.

I hereby affix my signature in the presence of two witnesses.

HORACE MERIAIVI.
