AUTOMATIC MACHINE FOR GLASS BOTTLES. 153 over the lehr (Figs. 3 and 4), with its 550° in waste heat and 850°(18) from glass, the air is first passed in iron pipes and then upthe recuperator to the burners. The gas from the producer(Fig. 5), is at a temperature of 700° or more, and the gas conduitin the recuperator brings it up to over 800°, so batch air and gasgo in at about the same temperature, and give the fresh heatlittle to do to raise the temperature to melting point, 1,150° pluslatent heat. Having explained the glass, heat and air problems,the machines for this mass production can be dealt with :—An 8h ft. dia. funnel requires a machine for 270 tons per week. 12 ft „ ,, 540 „ 14 ft. „ ,, „ 810 ,, 16 ft. ,, „ „ 1,080 „ The smallest is somewhat too restricted in area and the costand upkeep nearly as much as the 12 ft., as the wider the funnelthe better, if the height is always 10 per cent, more than thediameter above the cone proper ; this in the larger means
