two dAnges along their middle line leaving them
TO project equally on each side, and must be with
out bends or cOrTugatiOns
DIMENSIONS OF BEAMS.
Length oil fAil.......,. -......., II inches.
Depth between outer surfaces of
hanges ..,.......... ....... IS
Thickness OF fsnge at outer edge 80, 10 inch.
Thickness OF web ............... .62j
These beams will be inspected after the following
rules:
They arc TO be made Of good, tough, wel-worked
clear iron; the absence Of which qualities gener-
