Bend-pipe
A common name for all classes of curved pipes that are not distinctively elbows. The moulding of such pipes demands the attention of moulder and pattern-maker more than any other, simply because the constantly varying curves required make it impossible to keep a stock of patterns on hand for the purpose. Hence, all manner of devices for moulding are resorted to, to save pattern-making, and, at the same time, obtain a good casting. See JOBBING-MOULDER; LOAM-PATTERN; TOUCH.
