Danglish Apparatus

“The Danglish apparatus consists of the following parts: 1st, a generator A, in which carbonic acid is evolved from chalk by sulphuric or hydrochloric acid; 2nd, a gas-holder, in which the carbonic acid is stored for use after being purified in passing through water; 3rd, an air pump, for pumping carbonic acid from the gas-holder, and forcing it into the water vessel and mixer; 4th, another air-pump, for withdrawing atmospheric air from the mixer before the aerated water is admitted; 5th, a water vessel B, a strong cylinder of copper capable of withstanding a pressure of 100 lbs on the square inch, and of sufficient size to contain water for a full charge of the mixer; attached to this water vessel there are a gauge-glass C, and a pressure gauge D, for indicating the pressure of gas as it is pumped in; 6th, the mixer E, a globular vessel of cast-iron, capable of bearing high pressure, through the center of which an axle runs, fitted with iron kneating arms extending to the circumference of the vessel.” — Encyclopedia Britanica, 1893
