1. A braking mechanism for a railway car having a truck including side frames, pairs of wheels, a truck bolster resting on bolster springs contained in each truck side frame and a car body carried by said truck bolster, said mechanism comprising a brake pipe, and an air brake control valve connected to said brake pipe, an auxiliary reservoir connected to said control valve and an emergency reservoir connected to said control valve, a brake cylinder, a brake cylinder pipe connecting said air brake control valve to said brake cylinder, feeler means mounted in a feeler box on each side of the car body adjacent said truck for indicating vertical travel of the bolster with respect to said truck side frames, a load compensating cylinder assembly connected to said brake cylinder pipe, said assembly comprising a cylinder, a piston mounted in said cylinder, a T-bar having one end mounted on said piston, pawl and rack means operatively connected to said T-bar, equalizer means mounted in one of said feeler boxes for receiving vertical movement indications from each of said feeler means and sending a corresponding indication to said pawl means.
2. A braking mechanism according to claim 1 wherein each of said feeler means comprises a feeler tube containing a stiff spring, said tube having an end member extending outwardly, said end member being mounted adjacent the truck side frame for movement proportional to the weight of said railway car.
3. A braking mechanism according to claim 2 wherein said equalizer means comprises an equalizer bar mounted in one of said feeler boxes, linkage means connected to the outer ends of said equalizer bar to said feeler tubes, means connecting the mid-portion of said equalizer bar to the pawl in the load compensating cylinder assembly.
4. A braking mechanism according to claim 1 wherein said feeler means and said equalizer means comprise an equaLizer bar mounted in said one of the feeler boxes, means operatively connecting said equalizer bar to said pawl and rack means, a first feeler lever connected to said equalizer bar, a member extending outwardly of said feeler box adjacent one of the truck side frames for movement proportional to the weight of said railway car, means connecting said member to said first feeler lever, a second feeler lever mounted in the other of said feeler boxes, a rod connecting said second feeler lever to said equalizer bar, a second member extending outwardly of said other feeler box adjacent the other of the truck side frames for movement proportional to the weight of said railway car, and means connecting said second member to said second feeler lever.
5. A braking mechanism according to claim 1 wherein said load compensating cylinder assembly comprises a pawl pivotally mounted on said T-bar, said cylinder having an end wall, a return spring interposed between said end wall and said piston, a housing carried by said end wall, said housing having a rack mounted thereon for receiving said pawl, a ratio lever, a pawl bar connecting said pawl to said ratio lever, a sheathed cable having one end attached to said ratio lever for urging said pawl into engagement with said rack, the other end of said cable being attached to said equalizer means, a pawl spring connected to said ratio lever for urging said pawl out of engagement with said rack.
6. A braking mechanism according to claim 5 wherein said compensating cylinder assembly further comprises an opening in the end adjacent said piston for the passage of said T-bar, and lower guide means in said housing for guiding the movement of said T-bar.
7. A braking mechanism according to claim 1 wherein said equalizer means comprises an equalizer bar, and said load compensating cylinder assembly comprises ratio lever means connected to said pawl and rack means, cable means connecting said equalizer bar with said ratio lever means, and said feeler means being connected to said equalizer bar.
8. A braking mechanism for a railway car having a truck including side frames, pairs of wheels, a truck bolster resting on bolster springs contained in each truck side frame and a car body carried by said truck bolster, said mechanism comprising a brake pipe, an air brake control valve connected to said brake pipe, an auxiliary reservoir connected to said control valve, an emergency reservoir connected to said control valve, a brake cylinder, a brake cylinder pipe connecting said air brake control valve to said brake cylinder, feeler means mounted in a feeler box on each side of the car body adjacent said truck for indicating vertical travel of the bolster with respect to said truck side frames, each of said feeler means comprising a feeler tube containing a stiff spring, said tube having an end member extending outwardly, said end member being mounted adjacent the truck side frame for movement proportional to the weight of said railway car, a load compensating cylinder assembly connected to said brake cylinder pipe, said load compensating cylinder assembly comprising a cylinder, a piston mounted in said cylinder, a T-bar having one end mounted on said piston and a pawl pivotally mounted on the other end thereof, said cylinder having an end wall, a return spring interposed between said end wall and said piston, a pawl housing carried by said end wall, said housing having an opening in the end adjacent said piston for the passage of said T-bar, said housing having lower guide means for guiding the movement of said T-bar, a rack mounted on said housing for receiving said pawl, a ratio lever, a pawl bar connecting said pawl to said ratio lever, a pawl spring connected to said ratio lever for urging said pawl out of engagement with said rack, a sheathed cable having one end attached to said ratio lever for urging said pawl into engagement with the rack, an equalizer bar mounted in one of said feeler boxes, the other end of said sheathed cAble being attached to said equalizer bar, a first feeler lever connected to said equalizer bar in said one feeler box, one of said feeler tubes being connected to said first feeler lever, a second feeler lever mounted in the other of said feeler boxes, the other of said feeler tubes being connected to said second feeler lever, and a rod connecting said second feeler lever to said equalizer bar.
