C. E. DATH YOKE MEANS June 24, 1930.

Filed Feb. 15, 1929 Patented .une 24, 1930 UNITED STATES PATENT OFFICE GIIARLES E. DA'TH, or CHICAGO, ILLINOIS, AssIGNoR To W. H. MINER, INC., or CHICAGO, ILLINOIS, A ooRPoRATIoN or DELAWARE YOKE MEANS Application iiled February 15, 1929. Serial No. 340,112.

This invention relates to improvements in yoke means for connecting the coupler to the shock absorbing means of a railway draft rigging.

One object of the invention is to provide a simple and effective yoke means for railway draft riggings, wherein means is provided for supporting and properly guiding the same on the usual carry iron of the underframe structure of the car, and further lli having means for supporting and guiding the shank of the usual coupler to maintain the horizontal position of the latter with respect to the shock absorbing mechanism and the coupler of the adjacent car.

A more specific object of the invention is to provide a yoke having a hood member deiined by spaced side walls and spaced top and bottom walls, adapted to accommodate the coupler shank therewithin, the coupler shank being anchored to the yoke by the usual coupler key extending through slots in the side walls of the hood, wherein the bottom wall of the hood is upwardly offset to provide a horizontal shelf or ledge of relatively large area above the main portion of the bottom wall for supporting the coupler shank outwardly of the usual carry iron of the underframe structure of the car, the offset portion of the bottom wall being provided with spaced, longitudinally eX- tending ribs, having the bottom edgeyfaces thereofaligned with the under surface ofV the bottom wall proper of the hood to cooperate with the carry iron and support and guide the yoke in a horizontal path, the main portion of the bottom wall being provided with an upstanding rib havingthe upper edge face thereof aligned with the upper surface of the offset portion or ledge ofthe bottom wall to form therewith a continuous guide means for supporting and guiding the coupler shank in a horizontal direction.

Other and further objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawing forming a part of this specification, Figure 1 is a side elevational view of a yoke embodying my improvements,

the usual coupler being shown associated with the yoke, and the shock absorbing and follower means being indicated in dotted lines Figure 2 is a top plan view of the yoke shown in Figure 1 with the coupler omitted. Figure 3 is a front end elevational view of the yoke shown in Figure 2. And Figure a is a vertical transverse sectional view, corresponding substantially to the line 4.-4 of Figure 1, with the coupler omitted.

In said drawings, the coupler, which is of standard dimensions and design, is indicated generally by the character 10; the same comprises the usual shank of substantially rectangular cross section, having the coupler head 11 at the outer end thereof, the coupler head being only partly shown in Figure 1. The coupler shank is anchored to the yoke by the usual coupler key 12 which extends transversely through the shank 10.

In carrying out my invention, I provide a yoke member having top and bottom spaced, longitudinally extending arms 13-13 connected by a vertical section 14 at one end, which is formed integral with the arms and cooperates with the inner end of a friction shell of a shock absorbing mechanism, the friction shell being shown in dotted lines in Figure 1 and designated by the character 15. At the forward end, the yoke is provided with a hood member defined by spaced, longitudinally extending vertical side walls 16--16 and spaced horizontal top and bottom walls 17 and 18.

As most clearly shown in Figures 1 and 2, the top and bottom arms 13 are in the form of fiat bar-like members and the top and bottom walls 17 and 18 of the hood form continuations of said arms. As most clearly shown in Figures 1 and 2, the top wall 17 is shorter than the side walls 1G and is inclined downwardly and forwardly of the yoke. The bottom wall 18 has the major portion thereof in substantial alignment with the bottom arm 13, the outer end portion of said wall being upwardly offset to provide a horizontally disposed supporting ledge 19 for the coupler shank. As

shown in Figures 1 and 2, the ledge 19 rojects forwardly beyond the side walls 16 of the hood and presents a relatively large` supporting surface for the coupler shank. The main portion of the bottom wall 1S is provided with an opstanding central rib or web 20 which extends rearwardly from the ledge 19 and has the upper edge face thereof in substantial alignment with the upper surface of the ledge. As shown in Figures 1 and 2, the rib 20 extends substantially to the inner end of the hood. As will be evident, the ledge and rib 2() together form a continuous supporting and guide means for the bottom side of the coupler shank for the major portion of the len h of said shank.

he side walls 16 of the hood are provided with aligned key receiving slots or openings 21-21 which accommodate the opposite ends of the coupler key 12. The slots 21are reinforced by flanges 22 at the outer sides of the side walls. The reinforcing flanges 22 are of greatest width at the front ends of the slots, thereby providing sullicient metal in the side wallsiof they hoodto withstand the strains to which the hood is subjected during outward ordi-aft movement of the coupler.

The yokeis supported between the draft sills of the under-frame structure of the car in the usual well known manner, by a saddie plate intermediate the ends of the yoke engaging the bottom arm V13 and a carry iron engaging the under side of the wall 18 to support and guide the front end" of the yoke. The ledge 19 is preferably provided with two depending, spaced, longitudinally disposed ribs or webs 23-23 which extend forwardly from the bottom wall 18 andA have their lower edge faces in ali gnment with and forming a continuation ofthe under surfaire of the main portion of the wall 18. The parts are so proportioned that the guide surface defined by the u per face of the l 19 and the upper e ge of the rib 20. an the guide surface defined by the under face of the bottom wall 18 and the lower edges of the guide ribs 23, are spaced such a distance apart vertically as to support the coupler shank of a standard sized coupler the proper distance above the carry iron to assure alignment of the couplers of adjacent cars and alignment of the couplerl shank with the shock absorbing mechanism. As most clearly shown in Figure 1, the connecting portion of the bottom wall, between the ledge 19 and the main portion of said wall, is preferably inclined and the outer edges of the ribs 23 are cut away on a. corre.` nding inclination.

he specific type of yoke yillustrated in the drawings is adapted for use in connectionwith a railway draft rigging, wherein the coupler has longer travel in buff than in draft and wherein a follower of s )ecial design is employed in connection wit the shock absorbing mechanism; the follower, which is shown in dotted lines in Figure 1 and indicated by 24, has projections at the front and rear sides thereof, which engage respectively the inner end of the coupler shank and the wedge of the friction shock absorbing mechanism, the wedge being shown in dotted lines in the drawings and indicated by 25, the wedge cooperating with the usual friction shoes of the friction means. By providing the projection at the front side of the follower, the use of a coupler having a shank of stamlard over-all len h is permitted.

hre top wall 17 of the hood has the front edge Ythereof inwardly offset with respect to the side walls so as to clear certain obstructions of the car underframe structure and permit the necessary outward movement of the yoke during a draft action. The side walls 16 of the yoke diverge outwardly at the forward ends, as indicated at E2G-26. so as topermit the necessary lateral pivotal movement of the coupler shank when cars are operated on curved track.

While I have herein shown and described what I consider the preferred manner of carrying out my invention, the same is merely illustrative and I contemplate all changes and modifications which oome within the scope of the claims appended hereto.
