Covering Sheet With Overhanging Continuing Edge Section Patents (Class 52/56)
  • Patent number: 7789023
    Abstract: An auto rack rail road car has a main deck and upper deck. It is provided with a door for controlling access thereto. The door is a radial arm door, and has a ladder mounted thereon by which personnel can ascend the second deck when the door is open. A second ladder is mounted to the first deck so that when the door is open the second ladder is positioned to co-operate with the first ladder. The arcuate path of the door is free from overhanging obstructions. The door also has internal and external weld-free stiffeners member for enhancing the rigidity thereof. A roller mounted to the door permits the door to be moved between open and closed positions. The door may further include a lock. A guide member protruding from the door co-operates with a groove in the main deck which slidingly guides the door as it moves between open and closed positions to control access to the car.

  • Patent number: 6412251
    Abstract: A panel system includes a first skin, a second skin, a web core constructed from sheet material for securing the skins together in a spaced, sandwich relationship, and a connecting means for affixing the web core within the skins. The web core includes a plurality of spaced apart longitudinal members having longitudinally spaced projections extending therefrom and further having transversely aligned, longitudinally spaced slots therein. The web core further includes a plurality of spaced-apart, transverse cross members each having spaced slots therein receiving the longitudinal members at corresponding transversely aligned slots thereof to provide an interlocked grid between the first and second skins. The grid is connected to the skins utilizing the projections, which extend through slits in the skins to facilitate welding or otherwise bonding the components.

  • Patent number: 6224125
    Abstract: A top rail assembly (20) utilizes a support brace (22) and an awning mount groove (26) recessed in a rail body (24) to provide a strong top rail assembly (20) without using undue space or degrading aesthetics. The brace (22) extends between a side wall brace tab (72) and a roof brace tab (64) to reinforce the top rail body (24) and define a wire chase opening (76) between the brace (22) and a transition section (74) of the body (24). The groove (26) is recessed into the rail body (24) and is defined by two opposed legs (80, 82) and a bottom segment (84) which are integral to the rail body (24).

  • Patent number: 5231815
    Abstract: The present invention describes a unique wall construction and spacer for use by unskilled labor in such construction. The wall comprises a plurality of blocks arranged in layers one above the other, each of the blocks having first and second sides, an exterior face, an interior face, a top and a bottom, and at least one cutout extending through the block between the top and bottom. The tops of adjacent blocks in each layer are adapted to be located in a common plane and each block is adapted to be separated from an adjacent block in the layer by a predetermined distance.

  • Patent number: 4455947
    Abstract: A railway hopper car includes an angular roof having a roof sheet provided with lateral edges each connected to the top of the car side sheet by an elongated top chord. Each top chord includes a substantially rectangularly-sectioned tube member affixed to the exterior of the top portion of the side sheet and includes a top wall inclined inwardly and upwardly and projecting interiorly of the car beyond the top edge of the side sheet. The undersurface of the lateral portion of the roof sheet overlies and is attached to a substantial portion of the upper surface of the top chord top wall. An inside wall on each top chord comprises a vertical member terminating in a top edge abutting the inclined top wall to provide a smooth vertical plane readily admitting installation of the side sheets and subsequent car interior lining.

  • Patent number: 4444123
    Abstract: A railway hopper car includes a curved roof having a roof sheet provided with lateral edges each joined to the top of a car side sheet by a top chord assembly. Each top chord assembly includes a top chord fully disposed within the car interior and having a vertical leg joined to the interior surface of a side sheet while an opposite inclined or angular leg is joined to the interior surface of the roof sheet. A curved cover overlies both top chord legs and forms, with the roof sheet and side sheet, a smooth continuously descending profile from the top centerline of the car roof to each of the car sides.

  • Patent number: 4275662
    Abstract: A roof structure for covered hopper cars has roof sheets with curved sections disposed on each side of a continuous trough hatch opening. A hollow, beam-type side plate connects the outer margins of the roof sheets to the side wall unit and includes an outer transition member with a curved section forming part of the side plate and also having a lip extending inwardly of the vehicle to form a continuation of the curved roof sheet. A connection piece underlies transversely extending edges of the roof sheets to join the sheets. Intermediate bulkheads or partition sheets have a rounded top to fit snugly for attachment to the curved roof sheets and are rigidified by stiffeners which extend horizontally and transversely of the vehicle from side plate to side plate and are connected thereto to join with the roof sheets and intermediate bulkheads to form a rigid roof beam which resists twisting and deflecting during transit.

  • Patent number: 4227354
    Abstract: A connection for joining the edges of a roof sheet to the wall of a railway car without the use of fasteners such as rivets or welds. The connection is weather-tight and includes an interlock feature which effectively carries the loading encountered during operation of the vehicle. A modified version of the interlock forms a trough for channeling water towards the ends of the railway car.
