A one-page dictionary entry on ironing and pressing machines, taken from Knight's New Mechanical Dictionary. It describes several 19th-century patented devices for tailors, laundries and hat makers, including those of Sanson, Thurston, Walker, Storrs, Leopold and Tyler. It also covers hat-ironing and block-ironing machines. Mechanisms, pressure systems (treadle, spring, lever) and heating methods (gas, steam, inserted heaters) are explained, with three illustrations.
