This movement 35 The draw-head A is provided in its front of the extension D and the link 0 causes the with the usual opening, B, in the middle of pin I to drop downward through the inner which is held to swing horizontally the link end of the link 0, whereby the link is held O, formed with an extension, D, pivoted at E in a locked position in line with the longitudiin the back of the draw-headA. The extreme nal axis of the draw-head. Now when the 4o inner end of the extension D is connected two draw-heads come together the locked link with the free end of a spring, F, fastened in O strikes against the curved plate G, either the draw-head A and serving to hold the link below, on, or above its link 0, so that the link 0 in an inclined position in relation to the of the second draw-head is swung outward longitudinal axisof the draw-head. Instead into its recess J in the projection K, and the 5 5 of the spring F a weight maybe employed to flange H is swung from under the lower end accomplish the same purpose. of the said pin I, so that the latter drops down- 011 one side of the link 0 and extending to ward into the front end of the coupling-link the extension 1) is formed a curved plate, G, O of the first draw-head. The cars are thus extending vertically throughout the length of coupled. 50 the opening B in the draw-head A. The It is understood that when the two drawcurved plate G is in front of the pivot E of heads are in a coupled position the link 0 in one draw-head extends in line with the horizontal axis of the draw head, while the link of the other draw-head is moved in its outermost position in the recess .l.

\Vhen the operator desires to uncouple the cars, he withdraws thc coupling-pin I of the second draw-head from the coupling-link C, so that the cars can be pulled apart. As soon as the operator moves this coupling-pin I into the position shown in Fig. 3 the link 0 of this draw-head is swung to its normal position by the action of the spring F, whereby the flange ll again passes under the lower end of the coupling-pin I and supports the same, as above (lCSCl'llJOtl.

of the d aw-head opening, a flange formed on the upper end of the said curved plate, a pin held to slide in the draw-head and adapted to be supported on the said flange, and a spring or weight for holdi ng the coupli ng-link in a normal position, substantially as shown and described.

4. In a car-coupling, the link pivoted in the draw-head and provided on one side with a curved plate extending vertically essentially the height of the draw-head opening, substantially as shown and described.

5. In a car-coupling, the combination, with a draw-head,of a link pivoted horizol'itally in 5 the said draw-head, a curved plate secured.

The operator can always see from the outside'which pin is to be withdrawn, as the in- 1 opening, and a spring for holding the said active coupling-link indicates the respective draw-head.

It will be seen that the coupling is adapted for draw-heads of various heights, as the entering link can engage the curved plate G of the opposing draw-head anywhere in the height of the draw-head openin It will further be seen that the coupling is automatic in every respect, and is very simple and durable in. construction. Instead of using one single spring 1 as illustrated in Fig. 1, I

inay employ two springs pressing against the opposite sides of the extension D.

The pin I is preferably raised by a suitable mechanism connected with the sides of the car, so that the operator can raise the pin in position without stepping between two cars.

llavin thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A ear-coupling ctnnprising a draw-head, a link pivoted in the said draw-head in the middle of the draw-lnead opcnin g, and a curved plate secured vertically on one side of the said link and extending essentially the height of the draw-hcad open i ng, substan t ially as shown and described.

2. A car-coupling comprising a draw-head, a link pivoted in the said draw-head in the middle 01' the draw-head opening, a curved plate secured vertically on one side of the said link and extendi ng throughout the height of the draw-head opening, a tlange formed on the upper end of the said curved plate, and a pin held to slide in the draw-head and aiflapted to be sup rjn'ted on the said flange, subs!antiall as shown and described.

A ear-coupling comprising a draw-head, a link pivoted in the said draw-head in the middle of the draw-head opening, a curved plate secured vertically on one side of the said link and extending throughout the height vertically on one side of the link and extending throughout the height of the draw-head link in a normal position out of line with the 1 axis of the draw-head, substantially as shown 5 and described.

6. In a car-coupling, the combination, with a draw-head provided on one side with an ottset having an interior recess, of a link pivoted in the said draw-head and mounted to swing horizontally, a curved plate secured vertically on one side of the said link and extending throughout the height of the draw-head opening, a flange formed on the upper end of the said curved plate to support the coupling-pin, and a spring for holding the said link in a normal position, substantially as shown and described.

7. In a cal-coupling, the combination, with a draw-head provided on onesidc with an oil?- set having an interior recess, of a link pivoted in the said draw-head and mounted to swing horizontall y, a curved plate secured vertically on one side of the said link and extending throughout theheight of the draw-head opcning, a flange formed on the upper end of the said curved plate to support the coupling-pin, and a rod connected with the inner end of the said link to swing the same horizontally, said rod extending through the said draw-head to the sides of the car, sul'istantially as shown and described.
