7723. Abraham, F. April 15. Gas or oil burners, air supply to.-In order that the air supply may be heated on its way to the flame, it is caused partly to descend between the globe and chimney or between concentric chimneys e, f, and partly to enter by openings b, which are controlled by a hit- and-miss valve i. The air thus heated partly passes through the openings d to the mixing-tube of the burner, and partly through holes in g, under the control of the hit-andmiss valve h, to the space between the burner head and the chimney proper f. A disc hit-and-miss valve l may be substituted for the conical valve g, h.
