UNITED STATES PATENT i OFFICE.
JOHN H. PARMELEE, OF BRIDGEPORT, OONNEUTIOUT.
IMPROVEMENT IN CAR-COUPLINGS.
Specification fcrming part of Letters Patent No. 182,382, dated September 19, 1876 application filed March 20, 1876. a
To all whom it may concern .i
Be it known that I, JOHN H. PARMELEE,
of Bridgeport, in the county of Fairfield, and
in the State of Connecticut, have invented certain new and useful Improvements in Car- Gouplings; 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 which is provided 'With a spring for the purpose of making it more difficult to break the chain, thus preventing the loss of the coupling, which is the principal object of my Whole invention.
Figure l is a side view of the coupling when in use, and performing the office of a pin on one side and, link on the other, also the notch for supporting the pin; Fig. 2, a section on line 00 a: of Fig. 1; Fig. 3, a coupling with a round head; and Fig. 4 a coupling with a flatand cone-shaped head, which, when the coupling is in. use, is in a vertical position.
A is the pin end .of the coupling, and B the link end of the coupling;O, the concave interior shoulders of the draw-head; D, the notch in the rear part of the opening, between the draw-bars, to hold the pin in a horizontal position; and E the chain, provided witha spring at F.
The object of making a link and pin in com-' bination is to prevent the loss of the links,
and the object of providing the chain by which the coupling is fastened with aspring is to make it more difficult to break the chain, and
thus cause the loss of the pin.
The inside of the head of the pin isconvex,
and the inside of the draw-head correspondingly concave, for the purpose of accommodating the various relative positions of the,
cars, and the shoulder on the under side'ot the draw-head and notch are for the purpose of holding the coupling in a horizontal position to prevent bending the same when the cars come together.
The aperture in the pin, which performs the office ofa link, should be below the draw-bar when it is used as a pin, and the opening between the draW-bars longer than the link end projects in front of the bufier, or the posterior wall of the opening, between the draw "bars, may have a vertical ridge in the center,
with receding sides, so that if the head of the pin is forced back against it, it'will slide to' one side Without bending.
This coupling may be used with nearly if not all or the'others in use. I
Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is
l. The coupling herein described, having the head A and link portion B, substantially as and for the purposes herein set forth.
2. The combination of the coupling, having head A and link B, with the drawhead provided with-the concave interior bearings G,
g for the purposes herein set forth.
3. The combination of the coupling above described with the spring F in the fastening chain E, substantially as and for the purposes hereinyset forth.
In testimony that I claim the foregoing I have hereunto set my hand this 15th day of March, 1876.
JOHN H. PARMELEE.-
