A short dictionary entry from Knight's American Mechanical Dictionary defining gassing in cotton manufacture, the process of burning loose fibers and fluff off yarn by passing it quickly through a gas flame. It describes the gassing frame, with its row of jets and hoods, the bobbin-to-bobbin yarn path, and the brass notch that detects knots and turns the burner aside. An engraving (Fig. 2194) illustrates the machine.
