of the drawbar or strap coupling. The Z formed as well as the upper and lower flanges of the 55 end construction and bumper cap, are provided with aligned openings through which coupling pin or bolt 58 may extend, with its center substantially in alignment with the center line of the drawbar straps and directly outward of the ller casting apex. 'Ihe bumper cap is formed with an upwardly extending, rounded projection which is located to one side or the other of the center line of the drawbar and is so positioned that its axis will be at angle to this center line and preferably intersects the center line at the center of the coupling pin or bolt as is clearly shown in Fig. 4. This projection may be either pressed in the bumper top ila-nge 52 or formed by welding a short piece of round stock to the bumper top flange.

With the previously described construction it is obvious that when the car is b'eing'pull'd thel draw link 62 will be in the position as shown by full lines in Figs. 1 and 2 and by line and dash in'Figs". Llatini 5. In this position the link is raised vertically and spaced from the bumper flanges with one side lof the link resting upon the top of the projection 6U. When the draft is lre"- leased and vthe cars start toward eavzhv other on a buffing action the link will, of course, Ybe thrown t-o one side by theprojection and will assume the position` shown in full lines on Figs. 4 and 5. With the link thrown to one side and the cars continuing their buff action, the link will be moved backward until the rearp'ortion contacts one of thev diverging walls ofthe filler casting which will further throw the link to one side and intothe position shown by line and dash in Fi-g. 1. In cases where the buff actionwmight take placeras the car was roundingl a curve and the coupling link resting substantially at right angles to the axis of the projection, the projection would, of course, have no effect in throwing the link to one side, but with the link in this vangular position as it moves backward it would again be deiiected by one of thediverging of the filler block and would assume the position shown by line and Vdouble dash of Fig. 1. n It is thus seen that regardless of the position of the coupling link upon the commencement of the buffing.v action the link will be thrown to one side or the other, thus preventing its being crushed and that the bumper projection and improved filler casting cooperate to accomplish this result.
