Abstract: A railway truck comprising two-wheel and axle sets held in spaced relationship by a pair of side frames, a static bolster spanning, and holding in square relationship, the side frames, an active bolster overlaying the static bolster and supported thereon for limited vertical and lateral movement by springs the number, capacity and size of which can be varied depending upon the physical characteristics of the vehicle body supported on the center bearing of the active bolster.

Abstract: An improvement in an automatic coupling system for a railway car which is equipped with a mechanical coupler, a main air line adapted to be connected to a corresponding air line of another railway car, a main valve interposed in the main air line, and means for actuating the main valve responsive to intentional coupling of the railway car. The improvement, in its preferred form, takes the form of a pair of pilot-operated check valves connected in parallel to the air conduit supplying the actuating means to prevent flow of air therethrough when the main air line is charged but uncoupled at one end, and to maintain the flow therethrough when coupled to another car but with either car having a faulty interface valve actuation which would normally allow the main valve to close.

Abstract: An improvement in an automatic coupling system for a railway car which is equipped with a mechanical knuckle-type coupler, a main air line adapted to be connected to a corresponding air line of another railway car, a main valve interposed in the main air line, and means for actuating the main valve responsive to intentional uncoupling of the railway car. The improvement, in its preferred form, takes the form of an extensible pneumatic piston and cylinder assembly, one part of which is attached to the main body of mechanical coupler and the other part of which is operably connected to the operating mechanism of the coupler for opening of the knuckle of the coupler. The piston and cylinder assembly is operatively associated with the means for actuating the main valve so that upon actuation of the main valve during intentional uncoupling of the railway car, air will be admitted to the piston and cylinder assembly. Upon separation of the railway cars, air is bled from the system allowing piston and cylinder assembly to retract leaving the coupler open and ready for coupling. The bleeding of the cylinder and piston assembly is preferably effected through a pneumatic time delay circuit to assure that the assembly has been fully extended upon uncoupling of the railway car before operating pressure is lost in the cylinder and ram assembly.
