yJ 5 if .9 6 5 WITNES SES Oggi* y fwfikfg/m a stop member 17. rlhe stop member is provided for the Vpurpose ofilimiting the movement of the ball check 13, and is also i provided for the purpose -ofprojecting the oil admitted through pipe A directly against the face of the check valve to hold it against f the seat 12 formed on the inner end of the burner tip. YThe central contractedV opening` 18 formedV in the stop member contracts. the oil stream to such an extent', vas to strike theball check With sufficient force to retain it on its seat 12. Thisis of considerable importance, as the check valve Vunder ordinary operation forms a closure for chamber Y1Q, which prevents vany oil from enteringfthe chamber, except through the tangential openings 15. y

In operation, `as Apreviously described, it

is, foundthat the oil carbonizes'and builds upon the end loflthetipto Vsuchan vextent Vas to interfere'vvith the Voperation of the p `burnergit therefore lbecomes necessary to Y e Vremovethe 'tip' so 'thatrthe carbon collected vmay ybeV removed. This is accomplished by unscrevvi'ng cap 7 andfthen vremoving the burner'tip. If the fireman'v or attendant should happen tofforget to replace the clean y c `tip kor the one just removed after it has been Cleaned, no serious results'willbe produced,

in the-'present instance it' the oil :should: beV

turned on,A as the pressure of the oil discharging through the central opening'18 in the stop member 17V vvill force the ball check 13 outwardly against the annular tapered shoulderl 19orm'ed interior ot the sleeve 4. The oil is thus entirely cut oil andeX- plosion or `hre of any kind prevented. The 4operator yvvill then immediately see that the burner tip has 'notwbeen replaced aiidwvill then shut oil the oilV supply and insert the tip. Accidents of thelz'ind previously mentioned `will in this manner be avoided and theV operator willl at the same time lmoiv "that afburner tip must be inserted, as no recan be produced until the tip has been replaced, as the ball check Will remain on ,its seat 19 until the oil under pressure is turned otl.

lIn Fig. 3 a modification has been shovvn,

`in which a check valve 20 ofthe piston type has been employed; this valvevis provided `with a y' plurality 'I of outwardly projecting guidey members 21Which lform `spaces 22 through wvhich the oil is permitted to flow, exterior of the valve toenter the tangential openings 15 and chamber 10. -This typeoi' valve normally forms a closure for chamber 10, las lit also automatically seats on the tapered; seat 12 or formsga closure against the valve seat 19.

The atomizer with connected tip; and

check valve here shown is.V simple `and substantial in construction, can be cheaply dictate. Y'
