JOHN YEAGLY, OF FREDERIOKSBURG, OHIO.

IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 161,850, dated April 6, 1875 application filed February 4, 1875.

To all whom it may concern:

Be it known that I, JOHN YEAGLY, of Fredericksburg, in the county of Wayne and in the State of Ohio, have invented certain new and useful Improvements in Oar-Couplings; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of a car-coupling, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, which represents a longitudinal section of my car-coupling.

A represents an ordinary bumper or drawhead for railroad-cars provided with the flaring mouth B. The top of the draw-head is slotted longitudinally, as shown, for the passage of the coupling-pin O. The upper end of this pin 0 is provided with a longitudinal slot, a, through which passes a pin, 12, to fasten the pin between two cars, 01 d, on top, at the front end of the draw-head. The pin 0 is provided with a beveled shoulder, h, near the center, about one inch from the lower end of slot to, as shown. When the pin is dropped through the ordinary coupling-link D in coupling, this beveled shoulder engages a similar shoulder, 43, on the inside of the draw-head A, thus preventing the pin from working out. The lower end of the pin bears against a lip or shoulder, f, in the bottom of the draw-head. A coupling thus constructed with a rod, cord, or chain, m, attached to the pin, and extending to the top of the car, can be uncoupled from the top without running the risk of being crushed by climbing downon freight-cars to draw the pin. It is self-coupling, and the pin, being attached in the manner described, cannot become loose.

I do not claim a coupling-pin having a large opening in its center, through which is passed a connecting-shaft to prevent its disengagement from the draw-head, and allow its movement on the arc of a circle within a slot in the draw-head, as I am aware that such is not new. With my invention the pin is narrow and slightly angular at the top part, so that a straight upward pull will not allow it to rise. The slot (1. in the pin is just wide enough to allow a free movement up and down 5 hence it is perfectly guided down into the narrow recess in the bottom of the draw-head. This recess is of a width about equal to the width of the pin, so that the link cannot get caught under the pin and accidentally throw it up.

Having thus fully described my invention,

' what I claim as new, and desire to secure by Letters Patent, is-

The combination of the draw-head A, having a large slot in the upper side, a narrow opening in the under side, and having ears dd, and beveled shoulder i, with the bent pin O, having a narrow elongated and inclined slot, 0., and shoulder h, all constructed substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 31st day of December, 1874.

J OHN YEAGLY.
