SPECIFICATION forming partof Letters Patent` No. 278,573, dated May 29, 1883.

ApplicationledJanuaryl,1883. (Nomodcl.)

To all whom it may concern:

Be it-known that I, CHARMED. MARK, of Flint, in the county ot' Genesee'and Stateof Michigan, have invented new and usefull, Improvements in Gar-Couplings; and I do hereby declare that the` following is a full, clear, and exact description thereot',.reference bein g' had to the accompanying drawings, which form a part of this specitication.

This invention relates to certain improvements in car-couplings; and the invention consists in the peculiar construction of the various parts and their combination and operation, as more fully hereinafter described.

Figure lis a bottom plan, showing my coupling as attached to a car. Fig. 2is a vertical `longitudinal central section'. Fig. 3 is a like view `with the coupling-hook in position when not coupled to an adjoining car. Fig. et is an end View. Fig. 5 is a detail.

In the accompanying drawings, which form K a part of this specification, A represents' the two end sections of a draw-bar, and B the central section, which connects the inner ends ot' these draw-bars together, one of such drawbars being provided for each car. j For the purposes of this connection the central section, B', is provided with a yoke, a., at eachend, and to the ends ot' each of these yokes `is-secured a socket, b, through which the inner ends ot' the sections A pass, and are secured from `being withdrawn by suitable keys,c,-passing through slots in the ends of such sectionsA. The free ends ofthe sectionsAterminate in the hooks U.

D represents rectangular iron boxes resting` upon the plates or stirrups E-one for each end of the car. They are pivotally secured at their rear ends, each to its own section Aby the bolt or pin d, the plate E forming the i'ul- '4o crum, upon which such box D may oscillate as a lever operates, the spring Flimiting such `movement vertically. The free ends of this rectangular box terminate in an enlarged mouth, Gr, such enlargement being downward and lateral, as shown in Figs. 2, 3, and 4, and with the upper front portion ot' said mouth closed by the overhanging part of the casting H, leaving an opening, I, below for the link to enter. The mouth I is shown distinctly in 5o Fig. 3, and leads into an elliptieally-shaped wall of such chamber, allowingthe hook() to engage with it. This hook will always. be in the positioii shown in Fig. 2, except when forcibly raised for the purpose of letting the link free, or when raised by the entering link, and, as soon as its cud" passes the hook, the latter will drop and engage with it. vThe peculiar shape ofthe hook and the peculiar shape of the chamber J are. such that the link, when in place, will always project horizontally, and be held in that position except when the outer end omi' the link may be deliected to enter the coupling of a'n adjoining car which may `be upon a lower or higher plane. The sections A of the draw-bar are inclosed within the rectangular boxes D, and springs K are sleeved upon the inner ends of the sections A to perform the functions of springs of the usual character on draw-bars of' the ordinary construction, except that when `the draft is applied at oneend of the car it first exerts its force upon the coupling at the oppositeend ot' the car, and then upon the spring upon the section ofthe drawbar to which the drat't is applied, thc followers L beingso arranged with reference tothe springs, the sections A, and the points of resistanceM as to allow of this action. The timbers Linder the floor and sills of the car should of course be arranged with special reference to securing these couplings in place 5. but such arrangement is but an ordinary exercise of mechanical skill, requiring no inventive power to do this. `A pin `or link, N, passing through a suit-able slot or hole in -the top ot the box D, issecnred to each of the sections A, near their outer ends, and links or chains O are arranged with suitable levers, l?, so that the hooks may be elevated at will for the purposes of uncoupling from the top ot' the cnr or from the sides thereof', thereby' preventing the `necessity of entering between the cars for this purpose. I do not desire to contine myself to this precise method ofuncoupling, as any ot' the known methods may be adopted for this purpose. The rectangular boxes D, which inclose the draw-bar, perform the usual functions of buf- 'ers by their indirect connection with the springs K, being formed at the pivotal point d, where such boxes are connected to the drawbars, and should, from any accident, the hooks C be` broken, an ordinary coupling-pin may be inserted through` the hole in the top through x y 2. In a carco'upling device, and in combinawhich the pin N passes, and thereby form a coupling with the link, in which case these rectangular buffer-boxeswould become portions or sections of the draw-bar; but under no other circumstances will they `perform any of the functions of the draw-bar as usually constructed, except the functions of buing. They simply forxn. guides for the link and draw-bar.

What I claim as my invention is- 1. In combination with the buffer-box D and fulcrum-plate E, the hooked draw-bar A, having the said box D, pivoted at its rear end thereto, and provided with pin N and lifting devices, substantially as described, whereby when the draw-bar is elevated the front end of the buer-box is depressed and the coupling released', as set forth.

e Y y amava CHARLIE E. MARK.
