CARB-COUPLlNG.

SPECIFICATION forming part of Letters Patent No. 271,655, dated February 6, 1.853.

Application filed November 3, 1882. (No model.)

l'o all whom t may concern Be it known that I, JOHN J. PURSLEY, of Wetmore, in the county ot'Nemaha and State of Kansas, have invented certain new and uset'ul Improvements in Automatic CarsCoupling Devices; andIdo hereby declarethatthefollowing is a full, clear, and exact description ot' the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters ot reference marked thereon, which 't'orin part of this specitication.

This application is for an improvement upon that class ot' inventions known as car-couplings,7 and has for its object ease ot' manipulation, and to obviate and lessen the danger ot' accident, so ot'ten resulting t'roin their management, siniplicityot' construction ot' the several parts, die.

ln the drawings, Figure 1 is a top view, and Fig. 2 and end view, thereof. Fig. 3 is a longitudinal section ot` Fig. l. Figs. 4; and 5 are plan views, Fig. 6 is a trout view, and Fig. i a longitudinal section, ot a modification ot my invention; Fig. a top view.

The same letters of reference denote corresponding parts in all the tigures throughout the entire speciticatiou.

A is the draw-head, provided on its top with an opening, a, within which is pivoted, hingelike, a couplingplate, B. This plate is formed with a projection at its lowerend, somewhat resembling a hook, as shown at b, so as to catch thelink C automatically, when it is forced into the draw-head, and hold it. Said plate works in the opening u, and to the top of the drawhead, on a line with the opening, is provided a spring, c, which extends over the couplingplate, so that when the plate is forced up by the link C the spring forces it down again and secures said link. The spring also acts by its downward pressure upon the plate to keep it from dying up troni the jolting ot' the cars, a nd thus prevents them iro-in coming uncoupled. The mouth ot' the draw-head A converges inwardly, and in the bottom thereof is arranged a guide-tongue, D, the'shape'ot' which ofcourse corresponds to the side on which it lies. This tongue does not project outside of the end of the drawhead, and it is secured upon a bar, d,

which extends through the two sides l and 2 of the draw-head. At the inner converged portion thereot'thisbar niav have a handle, or may be bent to t'orm a crank, and can be made to extend as far out as the side ot' the car, so that when two cars are about to be coupled this handle can be grasped and turned so as to bring the guide-tongue D, with one end of the link C resting upon it, on a line withwhere the hooked end ot' the plate falls, and thus obviate the necessity ot' going in between the cars to couple them. The coupling-plate B bears on the surrounding metal which forms the draw-head, both above and below the link, as shown at 3 and 3', Fig. 3, thus relieving the strain upon it to a very great extent. This is animportantteatureot'theinvention. Instead ot' the-guide-tongue D being ot' a solid piece of metal, as intended with reference to Fig. 2, a

' bar, c, bent to the proper shape, can be used,

as shown in Fig. t5, and operated in the saine Besides the above-described coupling device, can be used the modification, as shown in Figs. 4, 5, G, and 7, which I will Vnow describe.

The top ot' the draw-head has cast iu it the recess a', ot` shape to permit the metal plate u2, havinglateral wings, to work back and forth. This is done by a sort of small lever extending down through a dome, G, pivoted therein, and is capable ot' being moved back and forth by the shape ot` the slot within which it works, the slots widening at the bottom, as shown at 4. This lever is long enough to extend down into a groove or channehf, made in the recess, and runniuga little back ot'it. The drawl1ead is provided with a hole for thecouping-pin, both at the top and bottom parts thereof. The guide-tongue D in this case also has a hole therein on a straight line with thosejust nien- Ationed,'and the metal plate a2 has in it a sort ot' oblong slot.

Having described the several parts, I will now describe their operation. The link C being i'orced into the draw-head (guided by the tongue D, operated by the handle d) by the two cars approaching one another, the couplingis made automatically by one end of the linkC striking the rounded side ofthe hook portion ot' the coupling-plate, which raises it, and it is `forced back by the pressure of the spring IOO 'and the link caught.

fhen the dome, 85e., are used the opera' tion will be obvious. The lever, extending down through slot 4 into the channel j' under the metal plate a2, is pulled backward, and op- 'erating against the plate pushes it out, the

coupling-pin F having been raised as high as permitted by the chain which connects the lever and pin, and is of length just sufficient to permit heilig raised high enough tor the metal plate a2 to slide under it, which holds it in readiness for coupling. Then, when the cars bump together, the plate is pushed in and the pin falls through, the guide-tongue in this case having a hole init also on a straightline with those in the top and bottom of the draw-head.

Having thus described my invention, what I claim ,is-

The draw-head, in combination with guidetongue operated by a handle, the spring, and couplingplate, said plate having the lug and hook-like projections, and bearing or resting against seats formed in the draw-head, whereby the strain upon the pivot ot' the plate is relieved, substantially as described.

In testimony that I claim the foregoing as my own I atlix my signature in presence ot'two witnesses.

JOHN J. PURSLEY.
