CAR-COUPLING.

SPECIFICATION forming part of Letterslatent No. 273,438, dated March 6, 1883.

Application filed November 1882.

To all whom it may concern:

' coupling, the coupling being shown in broken and sectional side elevation. Fig. 2 is an inverted sectional plan view of the coupling and timbers for holding the same removed from the cars and Fig. 3 is an end elevationof a car provided with one of my couplers, showing the device for uncoupling.

The invention will first be described in connection with the drawings, and then pointed out in the claims.

To the under side of the cars A A are, secured the diverging timbers B B, between which are held the hollow tapering bellmouthed castings O G, which latter constitute the draw-heads ot' the cars. These draw-heads are adapted to have vertical movement at their outer ends between the timbers B B, so that the hooked connecting-bars D D will enter the draw-heads when the cars are brought together for coupling, whether the cars are of the same height or not, and for this purpose I cast the draw-heads with the trunuion's a a, and form the timbers B B, with the recesses b b, which receive the trunnions, as shown in Figs. 1 and 2, and place under the draw-heads (between them and the supporting-plates E) the springs f, which normally hold the outer ends of the draw-heads elevated against the bottom edge of the cars, as illustrated in Fig. 3, but permit the draw-heads to be moved downward against the tension ot'the springs. ccare buffer-springs placed in the recesses b 12, against which the trunnions a a come when the cars are in motion, and these springs and the draw-heads are held in place in the recesses and between the timbers B B by the cleats d d and the abovementioned supporting-plates E, as will be understood from the drawings. The connecting- (No model.) I

11183.08 of the lips'i 71, formed respectively-on theconnecting-bars and the draw-heads, as

shown clearly in Fig. 1.

'F F are flat springs, secured in the throats of the draw-heads, as shown in Figs. 2 and 3, for causing the connecting-bars of the opposing cars, as the cars are backed together for coupling, to-be forced toward each other on entering the opposingdraw-heads to insure the engagement of the hooks of the connectingbars, and to keep the hooks engagedwith each other until the bars are forced apart for uncoupling. The means for forcing the connecting-bars D D apart for uncoupling is shown clearly in Fig. 3, consisting of the verticallymovable bar Gr, formed with the cam h, and opening or slotj, through which the connecting-bar of the car passes to hold it in place. The cam It comes between the connecting-bars D D when the cars are coupled, as shown in Fig. 2, and the bar Gr extends nearly to the top of the car, where it is attached to the lever H, by which it may be raised, causing the cam h to spread the connecting-bars, thus disengaging their books, and thus uncoupling the cars.

. The bar Gr may be raised for uncoupling from either side of the cars by means of the levers J J, that are attached to the ears and to the bar G, as clearly shown in Fig. 3. Thus constructed it will be seen that the couplers are entirely automatic and certain in coupling; that the coupling-bars will enter the draw: heads and couple whether the cars are on the same level or not; that the coupling is cheap and perfectly practical, and that the cars may be uncoupled from the top or sides, thus entirely obviating the necessity and danger of going between the cars.

I am aware that it is not new to make a slotted draw-head slide horizontally and turn vertically on a bolt, or to hold it forward bye spiral spring; but

WhatI do claim as new and of my invention is- 1. A draw-head having the trunnions a a near its rear end, in combination with the timbers B B, attached to the body of cars, and provided with slots or trunnion-bearings b b, and the springs c 0, arranged in the recesses or bearings b, as and for the purpose specified.

The timbers B B, secured to the bottom of the car and formed with the recesses b b, in combination with the draw-heads 0, formed with the trunnions a a, as set forth.

3. A car-coupling connecting-bar formed with two hooks on the same side, one at the outer end and the other at some distance to the rear thereof, whereby it may couple, as described. v i

4. The combination, with the hooked draw- 20 bars D D, of the vertically-movable bar G, formed with the earn it, for uncoupling, substantially as described.

5. The bar G, formed with the slot or passage j for the connecting-bar, and with the cam h, as and for the purposes set forth.

6. The bar G,forn1ed with the passage j and cam h, in combination with the levers H and J, for raising the bar for uncoupling, as set forth.
