The purifiers arefor dry lime, with four tiers ofsieves, each carried on angle-iron, as shown in Figs. 3125 and3129. The sieves are made ofwood in square frames, as shownon the plan. Each purifier issupported on brick piers, whichare represented in Figs. 3125to 3127. The gas is made toenter the purifiers, and after. Elevation. GAS, MANUFACTÜEE OF. 1619 passing through the lime spreadover the sm-face of the sieves,makes its exit through thecorner pocket d. After passingthe purifiers the gas has onlyto pass through the stationmeter before being conductedto the gas-holder. The stationmeter is made to register thegas produced, and by working inconnection with a clock, showsthe relative quantities producedat each houi- of the day. Thegas-holders. Figs. 3131 to 3133,are each 80 ft, diameter ; a drywell is made by the side ofeach, through which the inletand outlet pipes are laid ; eachpipe is made to dip in a box atthe bottom of the well, fromwhich the water formed in thepipes is pumped out by meansof a hand-pump. The well c,Fig. 3106, answers for the twoholders, and the other well / isa reserve for the third holderwhen erected. A stop-valve is 3135.
