5 Claims. (01. 29—164)
This invention relates to a method of making
railway cars, and particularly a railway car side
wall.
One of the objects of the invention is the pro
vision of a new and improved method of car con
struction having novel arrangements of parts
whereby the car has minimum weight and max
imum capacity.
A further object of the invention is the pro
vision of a new and improved method of mak
ing outside sheathing for the sides of the car,
so constructed and arranged that the edges of
certain of the plates are overlapped and en

the said side sill and side plate, and the side
posts being disposed between the upright posts

while the sheets are arranged in substantially
the same plane and the welds extending sub
