the top of ladle. This cylinder should have a 2" hole at one end
for tuyere pipe, and should be daubed up same as a ladle, and dried

melted full of good hot iron in a short time. MAKING A CURVED PIPE

to make a curve of about thirty degrees in a pipe about three feet

in a creditable manner by the means shown in the accompanying
sketch. First I got a pattern for a draw-pulley rim, which was

of which is shown at e. In the under side of these cores was a
recess, to form the bottom flanges of the pipe. I also had a piece
of a circular flange pattern fitted to the outside of the rim
pattern, which piece of flange pattern was about one-sixth of...
