CAR-COUPLING.

' To all whom it may concern:

tion showing the connection between the coupler head and the\shank-.

'My invention relates to automatic couplers of the Master Car Builders type, and is designed to provide means for angling the coupler-head relatively to its shank in a vertical direction, so that when coupled with a -.co-acting coupler there is provided a Verti '20 flexibility of the two couplers, which permits the coupler-heads to adjust themselves to the irregularities in and changes in grade of the tIaCk .WlthO11i3 injury.

Referring to the drawings, the numeral 2 designates the coupler-head having a rearextension 3 are two outside projections 4 and 5, and a central projection 6, all of which projections have registering apertures for the insertion of a hbrizontally disposed pivot pin 7. At the forward end of the hollow coupler shank 8 are lugs 9 and 10, which en: ter between the projections 4 and 5 of the coupler-head 2 and take about the central projection 6.0f the coupler-head 2. These lugs 9 and 10 also have registering apertures for the reception of the pivot pin. The central projection 6 projects 'rearwardly of the bear; against the inside surface 15 pivot pin and has made integral therewith the

spring seats

11 and 12 upon which the

springs

13 and 14 are positloned, and which of the coupler shank. These springs are of sufficient strength, by reason oftheir bearing on the extension 6, to hold the coupler-head normally in horizontal central alinement with the coupler shank 8, the lower spring 14 Specification of Letters latent.

yieldingly resisting the downward move ment of the coupler-head. The .alinement of the co-acting couplerheads is preserved by reason of the vertical flat outer face 16 of the knuckle which engages the corresponding face of the opposing coupler when coupled therewith and under buffing stress. t

The location of the horizontal pivot pin 7 is as close to the coupler-head as is practi- Leable, and as it lies substantially at the uncture between the head and the shank of an ordinary coupler, it permits the greatest possible amount of angling resultant upon any given amount of movement of the coupler head.

The present day construction of cars and the position of the coupler thereon, as well as the small clearance provided in the contour line of the coupler, makes it impossible to allow for other than a very small change of angle in a vertical direction between the cars without damaging the coupler. Hence, the value of my device is obvious, since from the advanced position of the horizontal pivot, which I have described, a slight movement of the parts will admit of a relatively great change of vertical angle between the shanks of co-acting couplers.

What I claim is:

1. In a car coupling'mechanism of the Master Car Builders type, a coupler-head having vertically disposed projections extending rearwardly therefrom, a hollow coupler shank having vertically disposed forwardly extending lugs, a horizontal pivot pin, said lugs and projections having registering apertures for the admission of the pin, one of said projections having at its rear end spring sea-ts, springs mounted on said seats and bearing against the interior of the coupler shank, and being adapted to hold the coupler head normally in horizontal alinement with the coupler shank,

2. In a-car coupling mechanism of the cally extending lugs, said projections and lugs having registering apertures for the admission of a pivot pin, a central extension projecting rearwardly from the coupler shank to the rear of the pivot pin and being adapted to be positioned in the shank of the coupler, and to co-aot Withmeans for nor- J I I maliy maintaining the coupler head in horizontal ahnement with the coupler shank.
