TO ALL WHOM IT MAY CONCERN:

Bc itk=no`wntl1atL DAVID 'HARGEIL of Des Moines, in the county of Polk, and in the State of Iowa, have invented certain new and useful Improvements in Car-Couplings; and do hereby declare that the following is a full", clear, and eXact description thereof, reference boinfa`- had to the accompanying drawings, and to the letters of reference marked thereon. y

In the annexed drawings, making part of this specification, A A represent two jaws, which are pivoted .to n bar, C, as seen at :c a', near their rear ends. These jaws are pressed together by means of the rubber springs B B, which are held in place above and beneath the jaws by means of the bolt a, which passes through the jaws, and also through the centres of said springs. The month formed at the forward ends of these jaws is flaring, as soon, and within this month is a recess shaped like au arrow-head. D represents thedraw-bar, which has a hole in its forward end, and inserted in this holo is a coupling-bar, G. The rear end of this coupling-har is held in any suitable manner in the opening of the draw-bar, but so that it can revolve or turn in the line of its length when required. An arrow-head is the form oi' the forward end of the coupling-bar, undsaid head is made so that it will tit loosely within the recess of similar shape in the jaws A A. II represents a lover-handle, which is secured at one end tothe coupling-bar G. The outer end of this lever plays in ametallic or other keeper, I, so that it is allowed to move only such a distance. The jaws being attached to one car, and the draw-bar D to another, when the two approach each other the arrow-head of ba-r Gr forces open the jaws A until it enters its recess. The jaws then close upon it and-retain it.

To uncouple the cars the bar G is partially revolved until the plane sides of the head are presented between the jaws, then the bnr G withdraws very easily by moving back the ear. Cars will uneouple very readily with this arrangement in euse of accident, such as running oil` the track and upsetting, Ste.

What I claim, isv The revolving coupling-bar G, when constructed and arranged as herein specified, in combination with the lever II, koepel' I, and spring-jaws A A, as and for the purposes herein described.

In testimony that I claim the foregoing, I have hereunto set my hand, this 16th day of November, 1867.

DAVID HARGER.
