The accompanying cuts show approxi-mately the construction of the chamber, which is partly novel, atleast as far as the use of the cylinder with Archimedean screw isconcerned. In the sketch the letters represent: F, shaft-furnace; A, flue from furnace to chamber; B, smaller 310 PROGRESS OF THE compartment of chamber; C, larger compartment of chamber; D,chimney; E, Archimedean screw in sheet-iron cylinder, covered withtar; h, axis of cylinder, revolved by pulley, p, on the outside of Fig. chamber and gearing inside; H, discharge-valve in bottom of cham-ber ; d, slide-valve in partition wall between the two compartments,opened when the chamber and cylinder are cleaned; a a, revolving SILVER-LEAD METALLURGY OF THE WEST. 311 water-jets, to keep the sides of the chamber wet; c, level of waterin bottom of chamber and cylinder. In starting the furnace, F, the chamber is cold, and there is aninsufficient draft through the chimney, I), as well as danger of ex-plosions from the flaming furnace. Therefore, the top of the furnaceis at first kept partly open. In from eight to twelve hours thechamber is sufficiently warmed, and the flaming of the furnace has Fig. 26.
