l My invention relates to machines or apparatus for spraying liquids and more par ticularlyuto spraying nozzles7 or to a form vot delivery port to be used in connection vwith sprays of the well known type in which liquid is delivered into the center-vof a current of Compressed air or gas at the point of discharge, and controlled by a needle valve. -The purpose oi the invention is to Vprovide amore etlicient method or' atomiza-y tion.
The usual methodv o'i' breaking up Ythe stream of liquid or securing atomization is Vby surrounding the liquid'with a current of ,compressedair or gas. lIt has the objection that the outerjportions of the liquid strean'r Y receive theimpact of the airy while the cen-- ter of the stream, in certain circumstances,
vdoes not receive suiiicient force from the air to become effectively atomi'zed.
p Toovercome this difficulty I lprovide a Acentral passageor passages for compressed air as wellas the outer ring of air, and thus bring the force of the air, or gas, more intimately inrcontact with the liquid. The
result is vto secure-abetter atomization. This is particularly useful when liquids of a very viscous nature are employed, and it also eni ables atomization to be secured at alower air pressure which has the advantage that the line .particles of liquid are not so much diffused in` the atmosphere, and this imi; proves conditions for Workers who are spray' Ving substances deleterious to health.
This improved nozzle can be used as an independent unit or as supplemental to the ordinary pin valve nozzle which is usually employed where a nice controlkof the quantity of the liquid is required.
lence to the y accompanying drawings of which j i Fig. l is a sectional side elevation, of a nozzle according to my invention;
Y Fig. v2 is an end view; Y
Fig. 3 is a sectional side 'elevation oi' la vmodificatiomfand p A Y Fig. 4l is another view ofv the same modication with the cap'removed. 'Y
In the embodiment of my invention select# ed forV illustration, 1l is a cylindrical air delivery tubev containing within it a cylin drical liquid delivery pipe 2 having a needle valve at its forward end at which point the My invention win tenian-inni byxinfnn! 588,072, andin Great Britain October 15V, 1921.
volumel ol'diquid controlled by the position of the pointed rod 3. Secured to these delivery pipes for compressed air and liquid Y by a union nut 4 is yal cylindrical piece 5 hav-V ing a vapornozzlefand an interior liquid delivery port 7 into which is inserted a tub;
ular.-T-shaped piece 8 which provides for' a delivery of compressedfair in the center ot' 'the liquid delivery. By this arrangement an y i Y Without further elaboration, the forego;V
ing will so fully explain the gist of my invention, that this may, by applying current knowledge, readily adapt samef'for useiin` der various vconditions ot service without eliminating certain features which* may properlybe said 'to constitute the essential items of noveltyinvolved7 which itemsI intendedto be deined'and secured to me by the following claims. i' l I claim'z- 1 In an atomizing nozzle, abody having a cent-ral passage therethrough` a second passage through said body, means for supplying a liquid to said central passage,v means tor" feeding air under; nressure to said second n a n n passage a liquidrget member conin'iunicating with said central passage and -having a tapering portion .endingV in a' circular open- 1ng, a hollow cap fittingon saidbodyand'* communicatingiwith 'saidA second air, pa'ssage` and havingan opening` concentric wit-h said liquid jet member to form an annular oriiice,' acylindrical air jet memberywitliin` 'said'liquidjetmember andy .coaxial tlierewith and slightly spaced ytherefrom to toi-1n A a relatively narrow Vannular 'orifice' ,for said liquid, and means connecting ysaid cylindii-` cal air'jet member withthehollow portion ot said cap to supplyk said air to' both said i air `jets under substantially the 'same pressure.
Y In witness whereoi.,v I hereunto subscribe Vmy name this 28th day of August, 1922.
