Abstract
A covered hopper car having curved side wall units joined to a curved roof structure with a hollow beam side plate and having a reinforcing cap member on the roof sheets with a top portion spaced above the curved roof sheets and maintained in the spaced position by hatch coaming to reinforce the hatch openings. The car also includes a longitudinally extending hollow side sill with bolster posts located at each end and interconnecting the side sill with the side plate in such a fashion as to provide a reinforcing frame encircling the curved side wall sheets and curved roof sheets to hold the curved sheets in position during car movement.

A railway hopper car adapted to carry lading which is loaded through hatch openings at the top of the car and discharged at the bottom of the car through discharge openings, the improvement comprising:
- spaced side wall units extending the length of the hopper car and including a side sill connected to bolsters at each end thereof and a side plate;
- said side wall units comprising side sheets having an arcuate shape;
- bolster posts extending upwardly from the bolster connection with the side sill having means connected to the side sill and side plate to form structural reinforcing rectangles surrounding the sides and top of the hopper car;
- a roof unit having roof sheets extending across the top of the car and including curved portions sloping from the hatch openings, outwardly and downwardly to side margins adjacent the side wall units;
- said side plate located at the juncture of the roof sheets and side wall unit and including means connecting the curved portions with the side sheets;
- said side plate comprising a longitudinally extending beam member with a first portion abutting and attached to the top margin of the side sheets and a side extending outwardly from the roof sheets;
- said side plate also including a second portion having means connected to the side sheets and with said first portion forming a hollow beam on the outside of the hopper car and extending to reinforce the upper portion of the side wall units.
A railway hopper car adapted to carry lading which is loaded through hatch openings at the top of the car and discharged at the bottom of the car through discharge openings, the improvement comprising the combination of:
- a through center sill extending the length of the car;
- spaced side wall units extending the length of the hopper car and including a side sill connected to bolsters at each end thereof and a side plate;
- said side wall units comprising side sheets having a curved shape between the side sill and side plate;
- bolster posts extending upwardly from the bolster connection with the side sill having means connected to the side sill and side plate to form structural reinforcing rectangles surrounding the side wall units and top of the hopper car and combining with the center sill to form the car reinforcing structure;
- a roof unit having roof sheets extending across the top of the car and including curved portions sloping from the hatch openings, outwardly and downwardly to side margins adjacent the side wall units;
- said side plate located at the juncture of the roof sheets and side wall unit and including means connecting the roof sheets with the side sheets;
- said side plate comprising a longitudinally extending beam member with a first portion abutting and attached to the top margin of the side sheets and a side extending outwardly from the roof sheets;
- said side plate also including a second portion having means connected to the side sheets and with said first portion forming a hollow beam on the outside of the hopper car and extending to reinforce the upper portion of the side wall units.
