  • This arrangement does not allow opening of the entire end wall, but nevertheless considerably facilitates the loading of long objects, such as for instance pipes or the like, over the end wall, since the load need not be raised over the entire end wall but only over its stationary part. In this way there is obtained the same advantage as in the embodiment shown in FIG. 2O namely, that when the sliding roof is open and the flat 107 swung down, there is no longer any transverse upper beam in ythe way.

  • the stops 81 of the hand lever 76 finally come against the stops 82 of the supporting lever 79 (as shown in FIG. 16)
  • the supporting lever will be carried along upon the further swinging of the hand lever 76 and will raise the roof part 52 through the holder 77 (FIG. 17).
  • the front supporting rollers 55 travelY onto the vertical guides 86 on the crossbeam 8. These vertical guides 86 are only so long that after the raising process has -been completed, they again release the rollers 55.
  • one of the rollers 55 namely roller 55a is developed as a grooved roller.
  • the other roller 55 is smooth so that slight changes in the span resulting for instance from sudden loads on the relatively light roof do not lead to jamming or to the rails going olf their tracks.
  • the same arrangement is utilized in the case of the rear rollers 54 in connection with which, for the same reasons, the roller 54 is smooth while the roller 54a is grooved.
  • the opening process is now terminated until the rear roof edge 67 assumes a position at which it is protected by the deflector 65 against damage from hoist cables, hooks or the like.
  • the operator will stand on the platform 71.
  • a railroad freight car having a supporting framework defining a cargo containing space including a corner support post and at least one intermediate support post on at least one longitudinal side of said car, an opening being dened between said posts in said side, at least two sliding wall panels closing the opening in said side, said panels extending in a common plane with said corner and intermediate posts, overhead support rails for said panels positioned along said side for sliding each of said sliding wall panels out of said common plane and past said intermediate post and the other sliding wall panel, rollers connected to the upper portion of said sliding wall panels which engage said overhead support rails for supporting said panels and for rolling said panels therealong, and separate lever means pivotally positioned on support means on said car adjacent to said intermediate post out of the rolling path of said panels for engaging and swinging the end portions of said sliding Wall panels adjacent to said intermediate post in their closed position between a first position in said common plane and a second position out of said common plane with said rollers in rolling engagement with said overhead support rails.
  • said frame work includes two corner support posts on said side, an upper beam connecting the upper ends of said support posts, said overhead support rails including a first overhead support rail positioned along the upper outer portion of said sliding wall panels, and a second overhead support rail positioned along said upper beam out of said common plane and bending inward to said common plane at the ends adjacent to said corner support posts, said rollers including a iirst roller connected to each panel at the end portion thereof adjacent said intermediate support post with the panel closed, said iirst roller being positioned for engaging said first mentioned overhead support rail, and a second roller at the opposite end portion of each of said panels in rolling engagement with said second overhead support rail.
  • said lever means include a lever arm for each panel pivotably mounted on a supporting shaft attached to said car out of the rolling path of said panels adjacent to said intermediate support post for pivoting about a vertical axis of pivot, a claw connected to said supporting shaft for pivoting with said lever arm and a pin connected to each said panel positioned for engagement with the corresponding claw and for swinging said end portion of the corresponding panel between said first and second positions upon pivoting of said lever arm.
  • corner support posts each define a vertically extended recess to receive said panels in said closed position and form a labyrinth seal therewith.
