    Specification. Davies Improvements in the Method of Purifying Smoke. The method of purification consists in subjecting the smoke in its passage from the fire to the atmosphere to a distributed shower of water or other suitable liquid, which is caused to pass through the smoke in the same direc¬ tion as the smoke, but at an increased speed. The apparatus consists of a chamber or shaft, which is in communication with the flue from the fire, and 5 up which shaft the smoke rises ; it passes thence down another shaft connected therewith* and as it descends the shower is caused to rain rapidly through it, and the liquid becomes charged with sooty and soluble vapours, which are separated from the smoke and carried down and precipitated in a tank below, and the smoke thus purified passes onwards to the chimney. In chLmnies 10 having only a low temperature the cooling of the smoke would interfere with it rising up the chimney, therefore the chimney must be separately warmed by the application of waste heat from the fire.
