My invention relates to bloweofii Va1yes, to

be used in connection with; steam boilers or-- in c'onnection with any device where a con trolled quick release of pressure is desired.

v The objects of my invention-are to provlde adeviceof this character whichis new,"'novel, practical and ofutility {whichmaybe easily andquickly'installed; which will effect the releaseo'f-pressure, or o'fasubstance under apr'essures'from a steam boiler, a tank, a pump,

afreservoir, a pipeline and the like; which may be opened for 'useiins'tantly; which may be closed instantly; which may be operated by remote controlywhichwi'll be held closed the pressure it conservesfwhi'ch will not leak; which is inexpensiye to manufacture; which is easily installed the parts .o'firvwhich, when worn, may be repaired onthe premises and be easily and quickly replaced; which by the grindingof afvalyeand its Valve seat,

maybe entirely renewed; I which will be cient inperf ormi'ng. allthe services for wh ch it l'is'inten'ded; I I 1 *Vfalyes now infuse have provenexpensive 5' to manufacture and to repair, indeed,

they are susceptible repair, Due to the wear 'of operation and the action of substance under pressure which frequently contains mud, sludge or other hardparticles,'theyalves Q proper and their seats are'quickly cut away,

to suchian extent that the Valve may not 1 beclosed. Frequently the cresultjis the di'scardingof a the entire yal eand its replacement. I The usualiyalyeis-so constructed tha'tits' moying partsare not susceptible to quiokon 1 9129; 'Ser iaLNoj 359,075. I

It will be seen that the wear and cutting action of the substance under pressure, upon my device is limited to the ring valvejseat and the tapered, portion of the valve head; :Both

the valve head and the ring seatmay be easily removed for grinding or for replacement'by V new parts, by removal of said cap 17. o 1
