While I have illustrated'and described the in
vention as applied to a railwayfcar roof, it will 45
be; understood that the same is applicable to
other structural parts of a car,*such as‘it-he wall
thereof, or to a'hoppersi'de; the invention being
primarily concerned with the novel arrangement
of securing together adjacent ‘sheets, which are
under compression ‘or tension stresses, and at
the same time providing a sti?ening means for
said sheets.
The accompanying drawings illustrate the pre
ferred form of the invention, though it is to be
understood that the invention is not limited to
the exact details of construction shown and de
scribed, as it is obvious that various modi?cations
thereof, within the scope of'the claims, will occur
to persons skilled in the art.
I claim:
