CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N0.343,486, dated June 8, 1886.

Application filed March 9, 1886.

To aZZ whom it may concern:

Be it known that I, Fnnnnsco ST. 0. NoRRIs,

a citizen of the United States, residing at Shreveport, in the parish of Oaddo, State of Louisiana, have invented certain new and useful Improvements in Oar-Couplers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has for its objects to produce a car-coupler which will act automatically to couple two cars when coming together without necessitating the entrance of an attendant between the cars, and which may be operated I 5 by such attendant to uncouple the cars Without danger to life or limb, as more fully hereinafter specified. These objects I attain by the means illustrated in the accompanying drawings, in which Figure 1 represents a longitudinal vertical sectional view of one of the coupling-heads forming part of my improved coupler, showing the jaw dropped in dotted lines; Fig. 2, a perspective View of the pivoted or hinged 2 5 jaw forming part of the coupling-head; Fig.

3, a front elevation of the coupling-head;

Fig. 4, a longitudinal vertical sectional view of my improved coupler attached to the ends of two cars. In this View the parts are ar- 0 ranged to automatically couple when brought together; and Fig. 5, a longitudinal vertical sectional view of the same parts, showing the same coupled.

The letter A indicates the draw-bar of the car, which carries at its outer end the coupling-head B. The said draw-bar is formed with side extensions, 0, and a forward extension, D. Between the side extensions is hinged upon a pivot-pin, K, the shank E of a swinging jaw, F, which sets and works under the forward extension, D, as indicated in the drawings. The said jaw has a cavity, G,

at its forward end, which is provided with a flanged or flaring opening or mouth, H, for the reception of the coupling-link I. The

upper part of the jaw is cut away, as indicated by the letter L, Fig. 2, of the drawings, so as to permit the coupling-pin to drop through the link when the same is projected Serial No. 194,528. (No model.)

into the cavity below. Just behind the cutaway portion, above the cavity, is an abutment, M, upon which the coupling-pin rests when the jaw-is down and the coupler open for the reception of the link. The shank of the jaw is recessed on its under side, near the rear, and this recess oversets the pin N, which passes transversely across the space between the side extensions of the coupling-head,hav ing its bearings therein and above said shank, and extending from the lower face of the up per portion of the draw-bar is a lug, P, by which the swing of the jaw is limited. The lug P limits the downward movement or drop of the jaw. Through the lower part of the jaw, and in such position as to be in a direct vertical line with the opening in the forward extension, through which the coupling-pin passes when the jaw is up, is a similar opening, B, through which the lower end of said pin passes, and in which it is held to secure the link. When the jaws are in position to automatically couple, as shown in at of the drawings, the lower end of the coupling-pin rests upon the abutment before mentioned, holding it in position to be dropped through the link automatically when the cars come together. The linkupon entering the jaw throws it up, allowing the abutment to pass behind the pin,which, being thus freed, drops automatically into place, connecting the cars and locking the parts of the coupler, as shown in Fig. 5 of the, drawings.

To nncouple the cars,the attendant has only to withdraw the coupling-pin from the platform above; or chains or levers operated from the sides or top of the cars may be arranged for this purpose, so that it will be unnecessary for the attendant to enter between the cars, and thus all danger will be obviated.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. The combination, with the coupler-head having side and forward extensions, of the swinging jaw pivoted between said side extensions, and having a cavity and flaring mouth, and a cut-away portion and abutment, the abutment serving to hold the pin up until the link enters the jaw,and then automatically I In testimony whereof I afiix my signature in IO drop it through the link, substantially as 1 presence of two witnesses.
