. Be it known-thatwe, Sabineke H.. REED" and GEORGE A. REED, of FrederielrlcwnX in the county of Knox and State of Ohio, Vhave ivented u. new

and improved Automatic Gar-@ouplingg and we do. v hereby declare that the followipgs a full, clear, and

Drawing.

Figure l isa longitudinal centxjalscqtion of our carcoupling.-

Figure 2 -isa transverse section taken on line :t z of iig. 1.

Like letters ,of rete-rence' are used in the Vdesignation of identical partsjin both of the figures.

This invention relates to c. rfconpling; and

It consists in' inclosing within a draw-head or bumper a-double fastening for the link, so4 constructd that when the link is introduced into the draw-head-it will raise the rst fastening or pin,4 which in tn rn will raisethe seomidtastening, and in suchamanner-thatwhen the lfakrhas become fully or suciently introduced into thedraw-head the two fastenings will fall simultaneously into slots or-apertures in the link, the constructiozatf which link `forms a portion of our invention, and ednsistsin construct- .inw the same withtwo openir-.'s-or slots at each end a :as l t with the link enlarged at apoint between them, all of which willv be more fully described and explained in that-part of this'specilication which 'olows.

' To enable those skilled inl-thc drt to which'onr in' vention relates to make and apply the same, we will proceed to describe its constrncton'and operation. l 1n the annexed drawing ,forming a part of' this speciand also the arm which extends inward, and which is lsecured vto a .=pin, O. '.lhe length-of Vthe arm upon i part B is such asto throw 'the pin O into the position shown by dotted lines in lg.)` when the jaw B is raised. f*

' b is a rod attached 1.o the rear end of the armof '.jaw B, andrnay beof such length` as to reach thetop of the car when-desired, and which, when lifted, puts the parts B and C into the position shown by dotted lines in lig. "1',so that 'the link can be withdrawn.

D is-a link, having twoslots or apertures, (l d1, at each end, the outer ones' d* being narrower than the inner ones' Land having a wedge-shaped,enlargement, d2, between them. p l v 1 The operation may be stated as follows: The link' D the hand or by th'e action of the carscoming. together,

it striks theeccentric 'bar or jaw B, which risesasfit turns upon its pivotal point, which movement causes its inwardly-exteudedarm to raise the 4pin O partially above the link; the jaw, then passes over the opening#4 l all, its relative width being greater', when ils-encounters the wedge-shaped enlargement d, which raises the jaw still .higher and completes the raising of the pin G, when the pin C falls in the aperture all and the jaw B in theap'erture d.

Having thus'described our invention,

Whatwe claim, and desire to secure by LettersPatl The combination of the jaw Band pin C with the link D d d1 d2, whereby said jaw and pin will be. madev to register with the openingsd dl, respectively, thus forming-a doublesafetylock, substantiallyras shown 'and' described, and for. the purpose speciiied.

In testimony whereof we have signed our names-to this specification this 6th day ot August, A. D. 1870.
