Open Top Hopper Railcar with Lading Shedding Top Chord and Corner Cap and Door Operating Controls with Manual Overide

Abstract

A open top railcar comprises a pair of spaced trucks, a railcar body supported on the trucks, the body comprising a pair of side structures on opposed sides of the railcar and a pair of end structures on opposed ends of the railcar, and a top chord extending the length of the side structures and the width of the end structures, wherein the top chord includes an inwardly sloped top surface configured to discharge lading toward the interior of the railcar through gravity. The railcar may further include corner cap, or end cap members, with each corner cap, or end cap including inwardly sloped top surface configured to discharge lading toward the interior of the railcar through gravity. The railcar may be a hopper railcar having a plurality of discharge chutes forming pockets for the body which open to the interior with a plurality of door operated through a pneumatic door operating system and further including a manual door operating override for each door. The railcar may include a nonmetallic touch pad housing secured to the side structures and including a plurality of touch plates mounted in the housing configured for operating selective doors.

         2 . The railcar of  claim 1  further including a top chord extending the length of the side structures and the width of the end structures, wherein the top chord includes an inwardly sloped top surface configured to discharge lading toward the interior of the railcar through gravity. 
     
     
         3 . The railcar of  claim 2  further including corner cap, or end cap members, with each corner cap, or end cap including inwardly sloped top surface configured to discharge lading toward the interior of the railcar through gravity. 
     
     
         4 . The railcar of  claim 2  wherein the top chord is a closed extruded section. 
     
     
         5 . The railcar of  claim 4  wherein the top chord includes an inside stake attaching web, a lower surface having a width equal to at least a width of the side structure, a vertical outer surface extending from the lower surface to the top surface, and an inner surface extending from the top surface to the inside stake attaching web. 
     
     
         6 . The railcar of  claim 5  wherein the inner surface of the top chord includes an offset whereby the top surface has a greater horizontal width than the horizontal width of the lower surface. 
     
     
         7 . The railcar of  claim 4  further including corner cap, or end cap members, with each corner cap, or end cap including inwardly sloped top surface configured to discharge lading toward the interior of the railcar through gravity. 
     
     
         8 . The railcar of  claim 7  wherein each end cap includes a vertical extending lip at a distal end of the top surface of the end cap. 
     
     
         9 . The railcar of  claim 4  further including a manual door operating override for each door. 
     
     
         10 . The railcar of  claim 9  further including rotary shafts extending to each side walls with each rotary shaft including a mechanical coupling at a distal end thereof configured to receive a manual rotation member therein. 
     
     
         11 . The railcar of  claim 1  wherein the air cylinders are connected to a main operating lever configured to transmit force to a main operating beam assembly and link fulcrums associated with each door that can be engaged or disengaged via a mechanical latching system to open and close the associated hopper door. 
     
     
         12 . The railcar of  claim 11  wherein the two piece link fulcrums for each door are engaged and disengaged by a mechanical latching system. 
     
     
         13 . The railcar of  claim 12  wherein the mechanical latching system is operated by an independent air cylinder controlled by selective touch plates. 
     
     
         14 . The railcar of  claim 13  further including a manual door operating override for each door. 
     
     
         15 . The hopper railcar of  claim 14  wherein the manual door operating override further includes rotary shafts extending to each side walls with each rotary shaft including a mechanical coupling at a distal end thereof configured to receive a manual rotation member therein. 
     
     
         16 . The hopper railcar of  claim 15  further including a top chord extending the length of the side structures and the width of the end structures, wherein the top chord includes an inwardly sloped top surface configured to discharge lading toward the interior of the railcar through gravity. 
     
     
         17 . A open top hopper railcar comprising:
 A pair of spaced trucks;   A railcar body supported on the trucks, the body comprising a pair of side structures on opposed sides of the hopper railcar and a pair of end structures on opposed ends of the hopper railcar, and three discharge chutes forming pockets for the body which open to the interior with a plurality of transverse doors operated through a pneumatic door operating system, and further including a manual door operating override for each transverse door.   
     
     
         18 . The hopper railcar of  claim 17  further including rotary shafts extending to each side walls with each rotary shaft including a mechanical coupling at a distal end thereof configured to receive a manual rotation member therein.
