Transcriber’s notes:
The spelling, punctuation and hyphenation are as the original except
for apparent typographical errors, which have been corrected.
Italic text is denoted _thus_.
Bold text is denoted =thus=.
Bold, sans serif text, representing physical appearance e.g., of a
‘Tee’ shaped wrench is denoted thus ^T^.
Both ‘gauge’ and ‘gage’ appear in the text and have not been changed.
FIG. 454. is used twice in the original book, the 2nd occurrence has
been renamed FIG. 454A.
FIG. 551 was omitted from the original sequence of illustrations.
Units of pressure, e.g., ‘pounds’ and ‘lbs.’ should be ‘pounds per
square inch’ and ‘lbs. per square inch’ respectively, for completeness.
This is left as printed in the original book.
