RAILWAY-CAR-WALL CONSTRUCTION.
Specification of Letters Patent.
Patented May 24, 1921.
Application led March 25, 1920. Serial No. 868,516.
To aZZ'who'm. it may concern:
Be it known that I, CHARLns D. BoNsALL, a citizen of the United States, residing at Parnassus, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Railway-Car-Wall Constructions, of which the following is a specification.
This invention relates to railway cars and particularly to the wall constructionof freight cars and has for its primary oblect to provide a sheet metal car wall having strengthening ribs formed therein, so constructed and arranged that the plates forming the car wall may if desired be pressed cold.
A further object is to provide an improved wall construction of great strength and rigidity and in which the strength thereof may be ro ortioned in accordance with the probable istribution of the load thereon without unnecessary waste of metal.
The invention consists in the novel constructions, combinations and arrangements for carrying out the above stated objects and such other objects as may appear from the following description of certain preferred embodments of the invention illustrated in the accompan ing drawings.
In the rawings Figure 1 is an elevation of a car end constructed in accordance with the principles of my invention.
Fi 2 iS a horizontal section taken along the line 2-2 of Fig. 1.
Fig. 3 is an enlarged fragmentary perspective of one of the box ribs in the car wall. l
Fig. 4 is a fragmentary vertical section taken on the line 4-4 of Fig. 1.
Fig. 5 is a fragmentary vertical section taken on the line 5-5 of Fig. 1.
Fig. 6 is a fragmentary central vertical section taken on the line 6 6 of Fig. 1.
Fig. 7 is a fragmentary elevation of half the Width of an end wall showing a detail view of a modified form of construction.
Figs. 8, 9, and 1() are vertical sections taken on the lines 8-8, 9-9, 10--10, respectively of Fig. 7.
Like characters of reference indicate like parts in the several figures of the drawings.
I have illustrated the principles of my invention as applied to an end wall of an ordinary form of box car although it will be understood that my invention is applicable to car walls generally. The end wall 10 1s shown applied to a car having corner posts 11, side walls 12 and roof structure 13 and end'sill 14. The end wall 10 comprises a plurality of relatively narrow metal plates or panels 15, 16, 17, etc., which are preferably flanged at the vertical edges 18 for attachment to the corner posts ll. The number of plates comprising the wall may be varied to suit the requirements of the particular construction. The adjacent metal plates overlap for a considerable portion of their width and the overlapping margins are formed with relatively shallow channels 19 and 20 which increase in depth toward the center and gradually merge into the plane of the plate at the` sides thereof. The channels 19 and 20 in the overlapping margins of adjacent plates are pressed iii opposite direction so as to form in effect a strengthening rib 21 of box like form. The channels also preferably uniformly decrease in width toward the center of the plate so that the combined width of the siii'- faceg forming the sides and bottom of each channel is substantially uniform throughout the length thereof. With channels so proportioned, the draw of the, metal during the pressing operation is more nearly uniform across the plate and there is less tendency for the plate to warp or the metal to tear. The plates are riveted together along the lines 22 and 23 on both sides of the ribs 21. The depth of the channels is so proportioned that the strength of the hoi; rib formed by combining the two adjacent channels 19 and 20 is sufficient to meet the stresses likely to be imposed thereon. B v riveting the channels into a box rib.r the rih so formed is stronger than double the strength of the individual channels not riveted together. Accordingly the depth of the channels may be much shallower than that of separate channels or corrugations in the ordinary wall panel. By proportioning the channels as described above it is possible to press the same into the metal plates cold. With the channels so formed in the margins onl of the plate the draw in the metal is uni orm and small compared to the draw in metal plates in which the corrugations are relatively deep and pressed also in the central region of the plate. Corrugations so arranged and designed must be pressed hot. When the plates are pressed cold, the sides 24 of the channels are preferably formed with a relatively gradual slope so as to facilitate the drawing of the metal.
Preferably the thickness of the panels or plates is varied so as to avoid unnecessary waste of metal by the use of thicker plates than is necessary in a region where the stress on the wall is relatively low. The plates are relatively narrow in wi-dth and accordingly the strength of any region of the wall may be proportioned to the probable stress likely to be imposed on that particular region by using a plate of the correct thickness.
In Figs. 7, 8, 9 and 10 I have shown a modified form of box rib, in which the rib 25 formed by the channels 26 and 27 does not vary in width. The channels 26 and 27 vary in depth as shown in Figs. 8, 9 and 10 and are riveted together on both sides of the rib 25. With the exception of the uniform width of the rib, this construction is in other respects like that described in the construction shown in Figs. l to 6.
I claim:
