8 Claims. 1

The invention relates to a connection between the lateral margins of a roof and the upper margins of the side walls of railway cars and similar vehicle bodies. More specifically, the invention relates to a reinforcement of side wall and roof in the regions where the two meet.

The outstanding objects of the invention are a side wall and roof construction for railway cars and similar vehicles which is light in weight and simpler in construction than corresponding previous designs while giving ample strength to the trusswork represented by the vehicle body in its entirety.

With the above objects in view, the invention provides a shear panel in the region where roof and side walls meet, which shear panel reinforces the margins of the roof sheathing, constitutes part of the connecting means between roof and side wall, interconnects the upper ends ment illustrated in the attached drawing and de;

scribed hereinafter.

In the drawing:

Figure 1 is a small-scale side elevation of a railway car;

Figure 2 is a fragmentary side elevation of the roof in the region of one of the side door openings;

Figure 3 is a fragmentary sectional inside perspective of the connecting zone'between roof and one side wall, the section being taken along line 33 of Figure 1; and

Figure 4 is a fragmentary section along line 4-4 of Figure 2 on the scale of Figure 3.

The illustrated body has side walls S and a roof R. Windows W and doors D are provided in the body sides. While the drawing shows and the following description refers mostly to the construction on one side ofv the body, there are, of course, two side walls and longitudinal roof margins which may have substantially the same construction. a

The illustrated side wall structure comprises longitudinally spaced vertical posts Ill in the form of U- or Z-sections. One of suchposts is arranged along each vertical margin of the door and window openings. Adjoining posts are con' nected between successive door and window openings by shear panels II and they are interconnected between the door openings by profiles |2 extending from post to post and secured with them. Along the upper margins of the window openings, between such window openings and between the window openings and the door openings, the posts are, furthermore, interconnected on their insides by a chord member in the form of a sheet metal profile l3.

If the side wall is pre-assembled as a sub-unit before its connection to the roof, the upper ends I4 of the posts project freely above the upper margins of the panels profiles l2 and chord member l3. A gusset plate l5 at the inside. of the upper end of each or most of the posts may conistitute part of the side wall sub-assembly uni The roof R comprises longitudinally spaced and transversely arched carlines 6, the ends of which fit telescopingly and are secured in a U-section marginal chord member H, which member preferably extends over the entire length of the car and is arranged at the height of the top margins of the door openings. The carlines have longitudinally extending inner and outer flanges l8 and I9 which serve for the aforesaid securement to the walls of the channel section H. The outer arm I8 of each carline I6 is attached to the inside of longitudinally corrugated roof sheathing 20 extending over the entire length of the car forming with the other roof elements a deep transversely arched truss. The roof sheathing 20 is also secured to the outside wall of the chord member l1. 1

An extension 2| of the roof sheathing projects downwardly beyond the member H. The lower marginal portion of the extension 2| i reinforced and stiffened by a fiat web 22 in the form of a narrow elongated strip extending uninterruptedly in longitudinal direction between consecutive door openings or between a door opening and the end of the car. This strip 22 projects downwardly beyond the lower margin of the roof sheathing extension 2| and is formed at its lower margin into an upwardly facing channel 23. The channel portions 23 not ending at an end wall are provided with drain holes 23, between window openings or at other unobjectionable places. The web is secured to the bottoms of the corrugations of the roof extension 2| preferably by electric spot welding.

At the location of each or most of the carlines a gusset :plate 24 is interposed between and secured to the outer arms l8, carlines I6, and the 3 roof sheathing 20. Gusset 24 extends, furthermore, between the chord member I1 and the roof sheathing and overlaps part of the inside surface of the web 22 to which it is likewise secured, preferably by electric spot welding.

Above the door openings the extension 2! of the roof sheathing and the reinforcing web 22 with its channel 23- are cut out. In these regions the roof sheathing above the chord member H is reinforced by a web or panel 25 overlapping with its projecting marginal H portion the outside wall of the chord memberlland' having an outwardly directed flange 26 secured-to an angle member 21 which, togetherrwiththe flange and the margin of the panel-5, forms anaminterrupted continuation of the channel 23. In addition, the structure around the,upper pontion of the door opening is reinforced by membersZt.

If the roof is pre-assembled as a subeunit 'be fore its connection to; the side walls, then such {sun-unit :zcomprises the .@described -l carlines i 8, :nhord-r members l l, roof sheathing gil wither:- iten'sions zipvwebsgfifl with channels; gnwebs ifi .iwithanchannels,26,22, gussets 24,1 and reinforcesamentsdB.
