respective pairs beyond its opposite ends, or beyond the platforms forming such ends, whereby when a train of cars is equipped with my improvement the recess in the head of each beam 5 on one car will register with a wedge, 12 on a head on an opposing car; and the extent of projection of the heads is such as to cause the opposing recesses and Wedges to lap one another to a considerable distance in the normal extent of separation of the opposing car platforms. The space between the surfaces of the recesses and wedges is ample to avoid any obstruction to the normal vertical oscillations of the platforms in the running of the train; and the recesses being open-sided they permit free transverse movement of the wedges through the recesses under the lateral swaying of the cars, in running and rounding curves, while the opposing wedges and recesses always re main in their mutuallydapping relation under normal conditions, ready to subserve their cooperating purpose when the cars are forced one against the other, as in a collision. hen a collision occurs, the opposing heads, at the ends of adjacent cars, are forced together, causing the wedges, by their wedging engagement with the recesses, to securely hold the platforms in alinement and prevent the climbing of one car by another and resultant telescoping of one by the other. The force of the collision enters the wedges fully into the recesses, when the shoulders 12 abut against the outer ends of the recessed heads and further increase the strength of their interlocking engagement.

The particular shape shown and described of the recess and wedge of the opposing heads best serves the purposes of my improvement, though it is not intended to limit my invention thereto, except in such of the appended claims as specify that shape.

To all whom it may concern.-

Be it known that I, JAMES S. THOMPSON, a citizen of the United States, residing at Chicago in the county of Cook and State of Illinois, have invented a new and useful Im provement in Antitelescoping Devices for Railway-Cars, of which the following is a specification.

My invention relates to an improvement in the class of devices used as extensions at the ends or platforms of railway-cars to prevent them from telescoping in the event of collision.

The object of my improvement is to provide a construction of the means employed for the aforesaid purpose whereby their effectiveness shall be materially increased and whereby they shall afford full freedom of play to lateral swaying of the cars in motion and in rounding curves without impairing their operation.

In the accompanying drawings, Figure l is a broken plan View of the under-framing of the bodies of two coupled railway-cars provided with my improvement; Fig. 2 is a section on line 2, Fig. 1, and Fig. 3 is an end view of the under-framing of one of the cars of Fig. 1.

At each side of the longitudinal center of the under-framing 4 of a railway-car extend two substantial beams 5 and 6, of rectangular cross-section, which occupy the positions of and may supplant the sills which usually support the platform-work 7 at the uppermost of the series of steps. At their rear ends the two beams may be socketed into the body-bolster 8, and they are securely fastened between their ends to the framing, as shown. The forward ends of the beams project beyond the platform in the plane of the draw-bar, the yoke-support for which is represented at 9, Fig. 3. The projecting end or head of the beam 5 contains a V-shaped What I claim as new and desire to secure recess 11 essentially extending from side to by Letters Patent is: side through the head to render the recess 1. In combination with a railway-car, anopen-sided. The corresponding end or head titelescoping means comprising heads proof the beam 6 terminates in a wedge 12 of jecting beyond the end of a car at opposite V-shape extending preferably from between sides of the longitudinal center of its base, shoulders 12 on the end of the beam to one of said heads containing an open-sided register with the shoulders of the recess in recess and the other head having a wedge the head of the opposing beam, this wedge extending from it, for the purpose set forth. being of dimensions corresponding with 2.

heads projecting one of said heads containing a V-shaped open-sided recess and the other head having a V-shaped Wedge extending from it, for the purpose set forth.

In combination with a railway-car, antitelescoping means comprising shouldered beyond the end of the car at opposite sides of the longitudinal center of-its base, one of said heads containing a V-shaped open-sided recess and the other head having a V-shaped Wedge extending from it, for the purpose set forth.
