o f'Qleveland, Cu'yahoga county,'Ohio, have invented a: new and useful Uncoupling Mechanism for Car-Couplers, of. which the "following is a full; clearyand exact description reference beinghad to the accompan in'g drawings, forming "part of, this speci cation, in which- Figure I is a sectional side view showing my! invention ap'plie dyto a car coupling; Fig. a; cross-section showing the uncoupling mechanism; Fig. 3 is a plan view of a portion of the mechanism;-and Fig. 4

is a detail view-pf the coupler lock-lifting device. 4

- "My invent on has relation to an. uncoupling device for usel with bottom-operating car'co'uplers'; and is designed to providea simple and -eifeotive device of this charactei'. v "3 Thenature of my inventionwill be best understoodb'y referencetof'the drawings, in

of COHSiIllCtlOIl and arrangement,.- of the partsby those skilled in the art w-ithout departing from the spirit and scope of my inventionas defined in the appended claiins.

The rod 14 depends s'ubsta-n'tiall'y vertically from the freet'endsof the - levers 15 and 15, so that when the coupler moves back under 'f'a compressive strain,h the rod 14 will de scribe an arc about t nections between said r'odand levers; This e centers of the conmovement' does not disturbthe normal position of 'any of the parts oflth'e operating 7: mechanism, because the slight: upward movement of therod 14, due to its rotation, i'scompe'nsated for by the looseness of the engagement of its horizontal portion with the eyell' of the lever 11., When the coupler headisdrawn outwardly-by apulling force, the same conditions hold true,

' and the parts remain undisturbed. Y

It'will be obvious that my invention may beused with other forms of'coupler heads;

' that the draft gear'and-riggling may be of other specific forms fromizt at shown'and described; that the lifting devices may be changed asmay be necessary to suit the articular form of the-locking member to actuated; and that various other chan es may be made in the details of construction an arrangement of the several parts without departing from my 1 nvention.
