CAR-WALL CONSTRUCTION.

I Application-filed September 13, .1926. Serial No. 135,218.

The invention relatesto metallic wall constructions for railway cars being more particularly designed for use in the constructionof carends.

It is the object of the invention to obtain Figure 3 is a vertical cross section on line 3-3 of Figure l.

Figure 4 is a horizontalsection on line 4-4 of Figure 1.x

Figure 5 isanenlarged cross section of oneof the rolled paneled plates of wall is constructed. i

In the present state of the'art, car ends and other ear walls of various constructions have. beenformed from metallic plates pressed to produce corrugations, panels, ribs and other reinforcements. Such reinforced plates are formed from flat metal plates or sheets which originally are of uniform gauge but as an incidentto the pressing the metal is drawn in certain portions thereof with the result that the gauge is varying. Furthermore this drawing of the metal often has the effect of weakening the plate at the very point where the greatest strength is required so that the total strength of the pressed plate is less than might .be Obtained with a more advantageous distribution of the metal. structions as heretofore manufactured is that the panels or other portions of the metal which are in spaced planes are connected to each other by obliquely extending intermediate portions instead of being connected by webs perpendicular to the planes of the panels. The reason for this is that it is practically impossible to press such plates so that these intermediate portions are always more or less inclined.

To overcome the conditions as above stated I have devised a construction of car wall which is formed of rolled plates, said plates being provided with panel portions in which the of acar end em-' Another objection to such con spaced planes connected by intermediate PQrtions substantially perpendicular thereto and the construction is also one in which the gauge of the metal in the panel portions and intermediate portions is uniform, while the cross section at the corners is increased and extends to the plane of the outer face of each panel. Sucha rolled plate will have a very considerable degree of additional strength Over, any pressedwplate which can be produced fromthe same weight of metal.

A further feature of my improvement is I the carrying. of this spaced paneled construction to the cornerof the car and providingat such corner a post so fashioned thatit will cap the, ends of the panels and form a weather-proof joint therewith.

In detail A is a rolled metal plate having the parallel spaced panel portions B, B connected to each other by an intermediate web portion C which is substantially perpendicular tothe planes of said panels. The

corners D and D are of increased cross sec-' tion each of the oppositefaces .of the web C extending in thesame plane to the plane of the outer face of the panel. This distribution ofmet'alwhich may be readily made in rolling -but.which would be impossible in pressing, greatly increases the strength of the truss as does also the arrangement of the web C in a plane perpendicular to the planes of the panels.

As shown in Figure 5 the plate A is rolled with one full panel B in one plane and two half panels B in the spaced planes. These half panels are extended as indicated at B sufiiciently to form an overlap so that the adjacent plates may be secured to each other by riveting. With such a rolled plate construction a car end may be formed from the series of plates A, A A A riveted to each other along the lines E and covering the intermediate area of the car end.

F are posts arranged at the corners of the car and so fashioned on one side as to conform to the paneled plates and to cap the ends thereof. Thus, as shown, the posts F have portions F for fitting against the inner panels of the plates, portions F for fitting against the outer panels of the plates and intermediate portions F for fitting around the web portions C of the plates. In addition the posts are provided with a flat angle flange F for hearing against the side wall of the car body. Such posts are preferably steel castings which may thus be readily fashioned to conform to the plates.

The car end constructed as above described may be provided with a wooden lining Gr. This may be secured to wooden inserts H which are placed in the channels formed by the outer panels and may be secured therein by suitable means such as the bolts J. The lining Gr may also be formed of relatively thin stock inasmuch as it is bearing against the metal panels and wooden inserts throughout its entire length and is thus strongly reinforced.

While it have specifically described a car end it is obvious that the same construction might be used in other portions of a car wall. It is also obvious that the panel plate may be arranged as shown in Figure 3 or may be in reverse position or, in other words, either series of panels may be arranged on the outside of the car.

hat I claim as my invention is:

1. A car wall comprising a rolled metal plate having spaced parallel panel portions and intermediate portions substantially perpendicular thereto.

A car wall comprising a rolled metal plate having spaced parallel panel portions, intermediate web portions substantially perpendicular to said panels and corners at the intersection of said panels and web which are of increased cross section.

A car wall comprising it rolled metal plate having panel portions in spaced parallel planes, intermediate web portions substantially perpendicular to said panel portions and corners which extend substantially to the line of intersection of the outer faces of said panels and webs.

i. A car wall comprising a metallic plate having alternate, transversely extending panels in spaced parallel planes with inter mediate webs substantially perpendicular to said panels, the cross section of said. plate being uniform to its end and a corner post at the end of said plate fashioned to conform to said panels and web and to form a weathering cap therefor.

5. A car wall comprising a rolled metal plate having t'ansversely extending panels alternately in spaced parallel planes with intermediate web portions substantially perpendicular to said panels and a corner post ol an angle cross section having one of the flanges thereof fashioned to fit about said panels and webs and to form a weathering cap therefor.

l"). A car wall comprising a series of rolled paneled plates each plate having a full panel in one plane and a pair of panels of less width in a spaced plane with substantially perpendicular web portions connecting the said panels, the adjacent plates of the series being connected to each other by overlapping and connecting narrow panels to form panels equal in width to said full panels.

7. A car wall comprising a rolled metal plate having alternate transversely extending panels in spaced parallel planes with intermediate webs substantially perpendicular to said panels a cross section of said plate being uniform to its ends, and means at the end of said plate for weather capping the same.

In testimony whereof I aflix my signature.
