AGENT United States Patent U.S. Cl. 52-208 Claims ABSTRACT OF THE DISCLOSURE A doorway construction for a railway car in which a rectangular channel member is incorporated in the side frame unit of the car prior to the assembly of the unit to the floor underframing, and the subsequent assembly of the roof to the side frame unit. The side frame and floor underframe include side sill members which combine to form a box section below the floor level for great torsional strength, and combine with the door channel member to form a double box section at the door opening. The roof structure includes a sleeper member which likewise combines with the upper portion of the door channel member to produce a box section above the doorway opening.

Heretofore in the construction of railway passenger cars the door framing in the side walls has been incomplete at the time of final assembly of the side walls to the adjacent underframe flooring below and the roof above. Thus upon completion of the assembly of the side walls to the floor and roof, additional parts are fitted around the door opening to finish the structural makeup of the door framing. This has been found to be disadvantageous in that such installation is done outside the controlled environment of the side frame subassembly area. In addition, a further disadvantage has been that upon assembly of the major components, often times the structure defining margins of the doorways are severely stressed resulting in deformation or unevenness of the openings. This has often interfered with the installation of the additional parts required to complete the doorway framework. Other disadvantages have been that the workmen performing such tasks often labor under diificult conditions such as in partially lighted areas, and are required to handle the materials and tools in awkward positions. Accordingly, it is the principal object of this invention therefore to provide an improved doorway construction for a railway car which avoids one or more of the disadvantages of the prior art arrangements and which lends itself to a simplified assembly.

It is another object of this invention to provide an improved doorway construction in the side wall of a railway car which is complete upon assembly of the side wall to its adjoining underframe structure below and the roof above.

It is still another object of this invention to provide a novel doorway framing construction in the side wall of a railway car in the form of box-like sections in cross section and having great resistance to torsion and shear at the opening of the doorway.

For a better understanding of the present invention, together with other and further objects thereof, reference is had to the following description taken in connection with the accompanying drawings and its scope will be pointed out in the appended claims.

In the drawings, FIG. 1 is a diagrammatic perspective inside view of and including a cross section through one side of a railway car, showing a door opening in one of the side wall units and adjoining portions of the roof and underframe units;

FIG. 2 is a view of a portion of FIG. I greatly enlarged and partially in section contained within the elongated rectangular enclosure of dotted lines indicated by the numeral 2;

FIG. 3 is vertical sectional view taken along the lines 3-3 of FIG. 1 through the doorway of the side wall unit of the vehicle;

FIG. 4 is a vertical sectional elevational view taken along the line 44, greatly enlarged, and illustrating the construction of the top portion of the doorway and the adjoining roof portion of the car;

FIG. 5 is a vertical sectional view taken along the line 5-5 of FIG. 1 but showing in addition the ends of the floor structural members;

FIG. 6 is a greatly enlarged view of a portion of FIG. 3 encircled by the dotted line indicated at 6 illustrating the threshold portion of the doorway;

FIG. 7 is a view greatly enlarged of a portion of FIG. 1 contained within the dotted line circle indicated by the numeral 7;

FIG. 8 is a diagrammatic perspective view of a side panel sub-assembly having a doorway opening therein and viewed from the inside of the railway car;

FIG. 9 is a perspective view illustrating a frame of generally rectangular configuration which encircles the margins of the doorway opening;

FIG. 10 is a diagrammatic sectional view illustrating the manner of assembly of the lower portion of the side wall of the car to one side portion of the floor underframing.

With reference now to the drawings, there is illustrated a part of a railway car body fabricated of sheet metal such as stainless or low alloy steel parts. The body 10 of the car includes a side wall unit S with a door opening D, a transversely arched roof R and an underframe or floor unit U. There is a side wall unit S on each side of the car. All units extend over at least a major part of the length of the body, and the floor and the roof units extend from one side wall to the other. In assembly the side wall units are moved laterally inwardly for connection with the floor underframing, and thereafter the roof unit is lowered onto and connected to the top portions of the side wall units. The fragmentary illustrated parts are sufiicient however, for a complete disclosure of the invention.

Referring now to FIGS. 1 and 8, the side wall unit S includes outside sheathing members 11, 13 extending longitudinally on each side of the doorway opening D and short interconnecting sheets 14, 15 disposed above and below the opening. A rectangular frame 17 of channel cross-section is suitably joined to the sheathing about the margins of the opening. Pairs of Z-section posts 19 are disposed in spaced relationship on opposite side of the door opening and are interconnected as by arc welding to vertically spaced angle stiifeners 21. A side sill channel member 23 extending continuous for the full length of the car is secured as by arc welding on its upper flange portion to the lower ends of said posts 19. The continuous side sill channel is notched as at 25 to accommodate the lower portion 26 of rectangular frame 17. Upper plate means 27 constituting a roof are member is suitably secured as by Welding to the top portion 29 of door frame member 27 and to top flange surface of the posts 19. The member in addition includes downwardly depending tongue portions 30 which together with the outside sheathing 11 form a box section in cross section with the side vertical portions 31 of frame 17. The plate is secured as by arc welding on its upper flange portion to the lower ends of said posts 19. The continuous side sill channel is notched as at 25 to accommodate the lower portion 26 of rectangular frame .17. Upper plate means 27, constituting a roof arch member, is suitably secured as by welding to the top portion 29 of door frame member 27 and to top flange surfaces of the posts 19. The member in addition includes downwardly depending tongue portions 30 which, together with the outside sheathing 11, form a box-section in cross-section with the side vertical portions 31 of frame 17. The plate is provided with a line of apertures 33 above the top of the frame. The upper plate means in addition includes an inwardly curved or arched portion as at 35, which terminates in a horizontally flanged portion as at 35.

As seen in FIGS. 1 and 4, the roof unit R has longitudinally spaced Z-section carlins 37, a longitudinal double angle section sleeper 38, a longitudinal roof sheathing or skin 39. The carlins 37 have longitudinally extending inner and outer flanges 41, 42 secured to the inside of the upper vertical flange 43 of sleeper 38 and the inside surface of sheathing 39. The lower outside vertical flange 45 of the sleeper 38 includes an upwardly turned lip portion 46 which constitutes a rain gutter for the roof. Opposite and above the doorway a plurality of horizontally disposed channel beams 47 are connected as by welding at their opposite ends to lower portions of the carlin 37 by means of gusset plates 49. The aforementioned horizontally flanged portion 36 of the arched plate member is secured to the lowermost surfaces of beams 47.

Prior to assembly the roof unit R is placed above the side unit S, and held in the desired position thereabove, such as by more or less conventional assembly jigs. In this position, the outer sleeper flange overlaps the upper marginal edge of the outer skin sheathing 14. In addition, the inside flange 43 of the sleeper is aligned with the arched portion 35 of plate 27, so that as the roof is lowered in place the flange 43 rests on arch 35, as shown in FIG. 4. The two units R and S are thereafter permanently secured to each other as by suitably spot welding indicated as at 51 and 53 respectively. It should be especially noted, the aforementioned holes 33 in the arch member 27 permits internal access to accomplish spot welding between the downwardly depending flange 45 and the outer skin sheathing 14 along the axis indicated as at YY. Still referring to FIG. 4, it is noted than hanger bracket means 55 are aflixed in depending manner from the cross beams 47. The bracket means include a U-shaped track portion 53, for carrying a door mechanism 57, spaced outwardly therefrom.

Referring to FIGS. 1 and 10, the underframe floor unit U has a floor panel 60, reinforced by transverse members 61, and a side sill Z member 62. In the same manner that the side sill channel member 23 is notched as at 25 to accommodate the door frame portion 26, FIG. 8, above side sill Z member 62, as best seen in FIG. 2, is likewise notched as at 63, to accommodate the door frame. See also FIG. 6. In order to compensate for the loss in crosssectional area of material removed by said notched portions 25 and 63, a reinforcing channel 65 and a plate 66, FIG. 6, are suitably welded to the inside face of the vertical flange 67 of Z-member 62.

Referring now to FIG. 10, which shows portions of the side wall and floor beyond the notched door area of the side sill members 23, 62, it will be recalled as previously stated, that side wall S containing side sill channel 23, is moved laterally to embrace the side sill Z in the direction of the arrows as shown. In the assembled condition, the side sill channel 23, and side sill Z-member are joined as indicated in FIG. 7, and are thereafter secured in place by welds 68, 69. In the door area, FIG. 6, the abovereferred to door reinforcing channel 65, is shown in facing contact with the inside face portion of door frame 26, and is welded thereto as at 71. Access holes 73 in the web of reinforcing channel member 65, enable welding of the channel and Z-sills, as at 75. With the reinforcing channel 65 so secured, a gusset plate 79 is thereafter aflixed to the base portion 26 of doorframe 17, and the vertical sides 31 thereof, to the adjoining upright post 19, FIG. 2. It is noted that the gussets 79 form a box section with the frame and posts to provide a high shear and torsion resistant structure.

With the primary structure so completed as above described, a floor consisting of plyboard 81, placed over beams 61, and a cast threshold plate 83, extending through the doorway, is provided to finish the door construction as indicated in FIG. 6.
