IMPROVEMENT IN RAILROAD-CAR. COUPLINGS.

Specification forming part of Letters Patent No. l13.375, dated June 2S, 1864.

To @ZZ whom, it may concern:

Be it known that I, RICHARD DOVER CHAT- TER'roN, formerly of the city of Bath, in that part of the United Kingdom of Great Britain and Ireland called England, but now residing in the town of Cobourg, in the county of Northumberland, one of the united counties of Northumberland and Durham, in the Provinee of Canada, have invented a new and Improved Coupling for Railroad0ars, the iuvention being also applicable to the attaching of draft poles and thrills to ordinary carriages; and I do he; eby declare that the following is a ful', clear, and exact description thereof, which will enable any person skilled in the art to make and use the same, reference being had to the accompanying drawings, making a part of this specication, in which- Figure l is a side sectional view of my invention, shown as a earcoupling, x Fig. 2 indicating` the line of section Fig. 2, a plan or top view of the same; Figs. 3 and 4, detached views of one form of shackle for the same; Fig. 5, a plan or top View of a modiiication of my invention, shown applied as a draft-pole coupling; Fig. 6, a section of Fig. 5, taken in the line y y.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in the employment or use of a shackle in connection with a pawl or catch placed in the draw-head, and all arranged as hereinafter fully set forth, whereby a self-connecting cai-coupling is obtained, and a coupling which will be applicable to the securing of draft-poles and thrills to ordinary horse-carriages.

A, Figs. 1 and 2, represents the draw-head of a car-coupling, which may be attached to the car in the usual or in any proper way. The draw-head is provided with the ordinary iiaring mouth or front, and in the upper part of the draw-head, just behind the flaring mouth, there is titted a pawl or catch, B, which may be of semi cylindrical form, and tted near its upper end on a shaft, c, the ends of which are allowed to turn freely in the draw-head. The dat or plane surface of this pawl or catch B faces outward and bears against the inner edges of the sides b, of the Daring mouth of the draw-head, the gravity of the pawl or catch having a tendency to keep it in that position, as will be understood by referring tc Fig. l.

C represents a shackle, which may be conl structed of a single bar, c, provided at each end with a head or knob, d, of cylindrical 'or other proper form, as shown in Figs. 1 and 2, or it may be constructed in the form of a link with a head or knob, d, at one end only, as shown in Figs. 3 and 4. The heads or knobs d should be of such a thickness vertically as to exceed the height of the space between the lower end of the pawl or catch B andthe back edge of the bottom c of the mouth of the draw head.

From the above description it will be seen that when one end of the shackle G is thrust into the draw-head t-he head or knob d will shove back the pawl or catch, and when the head or knob has passed the pawl or catch the latter will drop and the former Will be caught and retained between the lower end of the pawl or catch and the back edge of the bottom e ofthe flaring mouth-piece,as shown clearly in Fig. l.

In order to release the shackle C, the pawl cord, f.

The link-shackle shown in Figs. 3 and 4, is used in 'case one car of the two to be coupled is provided with the ordinary pincoupling. y

In order to apply this invention to the connecting of draft poles and thrills to horse-carriages, a head or knob, d', is formed on or secured to the inner end of the draftlpole A', (see Fig. 5,) and the pawl or catch B is tted between vertical plates g g, firmly secured on the front axle, D, or a bar at the front part of the vehicle, the head or knob d being caught between the lower end of the `pawl or catch B' and the axle D.
