The line or pipe `(i is connected to a union 28 yhaving a stuhng box'29 connected to its rear end, the rod through the union i and-also through a graduated dial 30 and or stem '21 continuing and said stuiiing box rearwardly from the latter to a hand wheel 31 which is secured to vthe rearzscrew'threaded extremity 32 of said rod or stem by .lock nuts 33. .Then dial 1 30 has ai'hub 34 secured to the rOdor stemEZlb'y a-keypin 3v5,`a11d in advance tothe orifice 23 Vwi ll Y of the said dial the rod 21 is screw threaded, as at 36, and has an adjusting nut 37 applied thereon betweeny which and a stop nut 38, a

spring 39 surrounds the said rod. The nut 37 constitutes a regulating nut, and between the stop nut 38 and the stuffing box '29 the angular member Ll() of a horizontal pointer lll is secured and'permanently held in place,

the said 'pointer 'having 'a 'rear reduced fex tremity l2 extending over the 'upper ,portion Yof the dial 30'. The dial 30 is :calibrated t0 correspondvto the pressure of the steam, air or gas supplied. through the line or pipe 7, and the valve 1-8 is retained in its valve seat 19 and is he'ld in place in accordance with ,a predetermined adjustment through the linediumof the regulating nut '37 which wi-ll be adjusted forwardly and bacltwardly to ifncrease or decrease the tension of the spring39.

Under ordinary operation, 'the valve '46 will be closed, so that steam, air under pressure or gas will be directly supplied through the pipe 48 to the union connection V50 and 'to the line or pipe 7 in vaccordance with the Vr equirenie'nts of the burner -and particularly suitable to the adjustment lof the oriflice QBjthrO'ughthe rnedium of the valve 18.
