Letters Patent No. 96,813, dated November 16, 1869.

, IMPROVED RAILWAY-CAR COUPLING.

The Schedule refen'ed to in these Letters Patent and naaking part of the same.

To all whom it may concern Be it known that I, JoHN D. Knnnrson, of New York, iuthe county of New York, and State of New York, have invented a new and useful Improvement in Oar-Coupling; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates (on new and useful improvement in couplings for railroad-cars, whereby many of the objections to ordinary car-couplings are obviated; and

The invention consists in the employment of a weighted lever, either double or single, and a sliding block, in combination with the draw-head, arranged and operating, as will be hereinafter more fully described.

In the accompanying drawings- Figure 1 represents a longitudinal side view of the coupling, as when the respective cars to which they are attached are coming together for coupling.

Figure 2 is a horizontal section through the line xx of fig. 1.

Similar letters of reference indicate corresponding parts.-

A A- are the draw-heads, which may be made in any suitable form, to admit of my arrangement for coupling the cars.

B represents a recess, back of the mouth C, which recess admits a sliding block, D.

This block is given a motion back and forth in its recess.

Its back motion is produced by the end of the link of the opposite car as the cars come together, while its forward motion is produced by means of the weighted lever E.

This lever has its fulcrum on the under side of the draw-head, as seen at 1*, and acts upon the block by means of the pins or lugs g in the block.

H is the coupling-link, and I represents the coupling-pin.

As seen in the drawing, the end of the pin in the draw-head A, rests upon the block D, but when the end of the link strikes that block, the block will be forced back, and the pin will drop, by its own gravity,

through the link, as seen in A, thus making the coupling of the car automatic and perfect whenever they come together.

The lever E may be double and act upon both sides of the block I), as seen in fig. 2, or single and act upon only one side.

In this example of my invention, I have adopted the double lever, and consider it preferable to the other form.

Theblock I) may be so recessed out that it will sustain the link in a. horizontal position where the cars are of uniform height.

\Vhen they vary in height, the months of the drawhcads may be made dishing, so that the link will be properly guided to the block, or the link may be raised and supported by a small rod from the side of the track, or from the car-platform.

The frontend of the block D is circled out, as indicated by dotted line in fig. 2, so that when the link comes in contact with it, the link will be so guided that the pin'will readily drop through:

The length of the chain J attached to the couplingpin, isdesigned to be such that the pin cannot be wholly withdrawn from its hole inthe drmv-head, as seen in the drawings.

It will be observed that no springs are employed in the arrangement, and none are required to render the operation of the coupling complete and perfect.

Having thus described my invention,

What I claim as new, and desire to secure by Lettors Patent, is-- The combination, with a draw-head and weighted lever, E, of the horizontal slide I), having the pins 9 51 upon its side face, as shown and'described.
