| A railway car door includes an operating mechanism having a pair of pipes and cranks rotatably secured to the door. By their rotation, the door is movable into and out of a door opening. The car is equipped to have internally-projecting lading restraining members removably attached to the inside car sidewall and filler members removably attached to the inside of the door. Pipe stops are provided for selectively increasing or decreasing the amount of rotation of the pipes and cranks possible so that when the filler members are attached to the door, the door can be moved laterally out of the opening a first greater distance and thereby permit the filler members to clear the sidewall or adjacent door of the car. When the filler members are removed, the door can be moved a second, lesser distance out of the opening and clear of the sidewall or adjacent door of the car. Adjustable door stops are provided for positioning a door and for protecting the door and a second car door, which may be adjacent thereto, from damage by impact with each other. The door stop is adjustable between a first position, in which the door stop member protects the doors from damage by impact with each other when an adjacent door is moved out of its opening the first greater distance, and a second position in which it is stored until next needed for protection of the doors from impact. | ||||||

| 224 | Grain door and method of installation | US477702 | 1974-06-10 | US3980124A | 1976-09-14 | William E. Bruning |
| A grain door for installation across the doorway of a boxcar wherein a generally rectangular relatively stiff panel equipped with a plurality of horizontal straps is equipped with diagonal fold lines extending from the intersection of the side flap and floor flap fold lines to permit folding the side flaps and the floor flaps ends into overlying relation with the remainder of said panel to facilitate anchoring the straps to the doorway posts. | ||||||
| 225 | End door for enclosed rail cars | US48442474 | 1974-07-01 | US3911831A | 1975-10-14 | BLUNDEN DONALD J |
| An end closure for a rail car which comprises a pair of foldable doors, each composed of a series of upright hinged panels. The first panel of each door is hinged at one side of the rail car. Each door may be secured across the end of the rail car in closed position when the panels are unfolded. The doors may be opened and secured in open position when the panels are folded and swung inward along the side of the rail car. The intermediate and upper decks of the rail car are formed with recessed or cutout portions to clear the panels when swung inward to open position. Hinged plates close or cover the cutout portions and also serve to hold the doors in open position.

| In a railroad boxcar, a reinforced door structure including a lower corner section of the sliding door engageable with another associated door or a fixed door post wherein the corner section is provided with a generally flat elongated right triangular gusset having its flat side against the flat side of the corner section, the right angle of the gusset being aligned with the right angle of the corner section, the upper angle section or apex of the gusset including a thickened integral boss inserted in the cutout portion of the front edge structure of the corner section, the boss having a hasp pin projecting outwardly for receiving the hasp on the post or associated door, the vertical edge of the gusset having an outwardly projecting offset door front edge engaging portion overlapping the inside of and being welded to the door front edge structure with the boss being spaced between the door front edge structure and the bottom door panel of the door structure, the sloping hypotenuse edge of the gusset being bevelled to deflect loading away from the door area where the gusset is located.

| There is disclosed a temporary load retaining barricade for the doorway of a freight carrier. The barricade includes a generally planar paperboard panel having corresponding fold and/or score lines which upon installation of the panel provides for an inwardly projecting floor flap as well as at least one inwardly projecting offset portion spaced above the floor flap for enveloping a reinforcing cross member of the barricade.

| 228 | Water drain structure for railway car door arrangement | US42536573 | 1973-12-17 | US3830167A | 1974-08-20 | TAMBORSKI R; PRZYBYLINSKI P |
| A railway car door of the sliding plug type is positioned within the door frame arrangement in the side of a car. The door frame arrangement comprises horizontally spaced side posts, an upper horizontally extending side plate structure and a lower side sill. The door posts which define the sides of the opening are provided with flanges which cooperate with flanges on the door to substantially close the door openings. The flanges on the door and on the side posts are also provided with a water drain structure including vertically extending lips which project outwardly with respect to the door opening and cooperate with waterguards supported on the post flanges to provide vertically extending drain troughs at the corners of the door posts.

| 229 | Sliding wall arrangement for covered railroad freight cars and containers | US35181173 | 1973-04-16 | US3828693A | 1974-08-13 | KAMPMANN G; SCHNEIDER F |
| Sliding wall sections are co-planar in the closed state and are movable out of the closing plane and into a shifting plane by operation of respective hand levers and actuating linkage connected to the hand levers. The wall sections are displaceable longitudinally, to open the sliding walls, on rolls engaging fixed wall parts and intermediate posts of a side wall frame having an upper stringer, a lower outer beam and corner posts. Sealing of the vertical edges of the sliding wall sections to each other and to the corner and intermediate posts of the side wall frame is effected by labyrinth packings. Each actuating linkage is operable to oscillate a respective upper shaft about a longitudinal axis, and each upper shaft has at least two levers extending therefrom and rotatably mounting rollers in their free ends. Brackets are supported on the floor of the container, adjacent the lower outer beam, by parallel linkages for substantially horizontal movement transversely of the container, each bracket including a vertical web plate on its outer end extending longitudinally of the container, and each web plate, in the outer position of each bracket, conformingly fitting in a cutout in a depending leg of the lower outer beam. The respective parallel linkages include levers secured to respective lower shafts oscillatable about a longitudinal axis by the associated actuating linkage. Arms on the upper portion of each wall section support runner rolls rotatable about horizontal axes, and have supporting cams cooperating with the first mentioned rolls. Lower supporting arms on each wall section rotatably support rolls for rotation about vertical axes and have channel-shaped guide clamps embracing the web plate of the associated bracket and operable to embrace the vertical leg of the lower outer beam. Each wall section, when moved into the shifting plane by oscillation of the upper and lower shafts, is displaceable longitudinally by engagement of its runner rolls with a continuous runner rail and by engagement of its lower rolls with the outer surface of the dependent leg of the outer beam. Interengageable metallic seals are provided on the ends of the wall sections, with each seal including a series of sealing sections arranged along the associated vertical end, the sealing sections having bevelled outer sealing surfaces which alternately slant in respective opposite directions. Profile strips at each corner and intermediate post are arranged to rotate about vertical axes and engage the ends of a wall section when the latter is being moved into the closing plane to guide the section obliquely toward the longitudinal center line of the container to effect tight sealing engagement of the sealing surfaces of the section with the mating sealing surfaces of an adjacent wall section already in the closing plane.
