Abstract
A covered railway hopper car includes a plurality of vertical partition sheets connected to the side walls of the car to form a plurality of hoppers. The connection of the vertical edges of the partition sheets to the inner surfaces of the side walls includes vertical posts of a cross-sectional configuration reducing stress concentration of the partition to prevent fracture.
Claims14
A railway hopper car including a car body having transversely spaced vertical side sheets,
- a plurality of diagonally extending slope sheets connected to said side sheets and forming a plurality of hoppers having lower discharge openings, and a plurality of partition sheets having laterally spaced vertical side portions for compartmentalizing said hoppers, the improvement comprising;
- means for connecting each side portion of each partition sheet to said side sheets within said car,
- said vertical side portions spaced from said side sheet,
- said means including a post connected to a side sheet and extending vertically therewith,
- said post having an outwardly extending leg,
- said vertical side portions being rigidly connected with said legs, and
- said means for connecting enhancing side sheet rotation upon loading of said partition sheet thereby reducing fatigue fractures in said side sheet to partition sheet connection.

A railway hopper car including a car body having transversely spaced vertical side sheets,
- a plurality of diagonally extending slope sheets connected to said side sheets and forming a plurality of hoppers having lower discharge openings, and a plurality of partition sheets having laterally spaced vertical side portions for compartmentalizing said hoppers, the improvement comprising;
- means for connecting each side portion of each partition sheet to said side sheets of said car,
- torsionally resistant hat shaped vertical side posts rigidly connected to said side sheets and extending vertically therewithin externally of said car,
- said hat shaped side posts being situated fore and aft of said means for connecting longitudinally of said car and
- said means including a metal plate member substantially vertically coextensive with said side sheet and connected adjacent to said side portion of said partition sheet whereby rotation of said side sheet is facilitated thereby reducing stress concentrations in said partition sheet to side sheet connections.
