"Patented apr. a, raie.
Application filed October 4, 1916i4 Serial No. 123,651.
' To all whom t may concern.'
Be it known that I, ERNEST H. PEABODY, a
citizen of the United States, resid-ing at New York, in thecounty of New York and/State of New York, have invented certain new and useful Improvements l1n ,'Atomizers or Spraying Devices, of which the following 1s a' specification.
My invention relateslto liquid atomizers and more particularly to onefor atomizing fuel oil, whereby the ollgmay be atomized and injected int'o the combustion chamberof a furnace, in the form of spray, by means of mechanical action induced by pressure.
In the accompanying drawing,V which illustrates one embodiment of my invention, Figure 1 is a central longitudinal section on the plane of the lines 1 1 of Fig. 2;.v
Fig. 2, an end elevation; Fig. 3, an enlarged central section on the plane of the line 3 3 of Fig. 4; Fig. 4, a half end elevation and half transverse section on the plane of the line el-i of Fig. 3; Fig. 5 aview looking toward the inner' l'face of the tip; Fig. 6, a side elevation; of the tip;L and Fig.
7, a transverse section' on the plane of theline 7 7 of Fig. 5. 0 I Similar reference numerals indicate similar parts inthe several views.
Referring tothe drawings the numeral 1f designates lthe body portion of the atomizer,
and 1X the goose neck in which is formed thev inlet port 2 leading to the enlarged chamber 3 is a strainer 6 of any `suitable -nozzle 7 X.
strainer chamber 3, the latter having a rear opening fl closed by a cap W'ithinthe construction, the purpose of which is to remove dirt or foreign matter which may be in the oil before the latter is delivered to the nozzle. The body 1 is reduced at its front -end and isA threaded to receive the internally threaded portion of a barrel 7. The bore of the barrel has a slight iiare at -its outer end and over said end is fitted a The latter is formed with a plurality of longitudinalfpassa'ges 8 extending from its inner conicalyface to an annularv channel 9 formed in itsouter face. Seated uponthe outer lface ofthe nozzle is .a tip 11 having a dischargeorice 12 at the apex of a central conical chamber 13. Upon its inner face the tip 11 is formedl with a plurality Of ducts 14: leading tangentially into the chamber 13 from openings 14', which Openings, when the tip is in position,
are located over and communicate with the annular channel 9, thus affording a continuous passage for the flow of the liquid from` the barrel 7 to the'discharge orifice. The nozzle 7X may be formed with any desired number of .passages 8, four of said passages being tangential ducts 14 in the face of the tip.
The forward end of the nozzle is eX teriorly threaded to receive a cap 10 having a central Opening 10 adapted to receive the central extended portion of the tip and to bear against the tip to clamp it Ifirmly in position upon the face of the nozzle. -The face of the cap is concaved at an angle so as to correspond with the -concavity in the end of the tip as clearly indicated in Fig. 3.
shown, with ai corresponding number of In operation, the liquid to be atomized enters through the gooseneck 1x and after passing through the strainer iows through the barrel 7 and is delivered from the passages 8 to the annular channel 9 in the face of the nozzle, through the openings l14 tO the tangential ducts 14 to the central conical chamber 13 and thence through the discharge Orifice 12. When passing through the central chamber 13 of the tip, the liquid is givena 'rapid whirling motion, and is a given time and under given condition,
such as natural or forced draft. I-Ieretofore, it has been the practice to interpose .between the tip and the face of the nozzle a separate member formed with ducts which, when the parts are assembled, are tangential to the wall" of the tip chamber, In the use of atomizers, itis frequently necessary when working conditions are changed to substitute va tip having a different sized discharge orifice, or the member having the 105 tangential ducts and, dueto faulty assembling of atomizers having discharge orifice in one piece and the tangential ducts in another piece, the proper ratio 0f the areas of' the oriiice and the ducts is not maintained.
` IVhen a tip having `a` relatively small 'discharge orifice is assembled with a separate piece having relatively large 'tangential ducts, the 'fuel may emerge in a stream and not beproperly atomized` Also, When a tip with a relatively large discharge orifice is assembled with a separate piece having relatively small tangential ducts, the atomiza i f tion of the oil may be excessive and fail to meet the required Working conditions. 'By making a plurality of unitary members,
each having a detinite area ratio between the discharge oriice and the tangential ducts, I thereby provide means to meet vaf rying working conditions of fuel and pressure and obviate all faultyr assembling.
' l/Vhile I have described' the duets 14- as` Jtangential to the Wall of the tip chamber-18,
I desire to include in said lterm Aany degree of ecoentricity of the ducts7 Which v'vill give to the liquid a whirling motion in said Chamber.
What I claim and desire to Asecure byLetl ters Patent of the United States, is i l. In a spraying device, in combination,
a nozzle having a channel in the face there-- of a'nd passages leading to said channel, al
tip having therein a chamber` with a dis vcharge orifice andduets tangential to the i I Wall-of said chamber, said `duets communieating With said channel, and a cap to clamp the tip-to the face of the nozzle.
2. -In a spraying, device, in combination, a nozzle having a channel in thefaoe thereof and passagesr leading t`o 'saidfch'anneh a tip having a conical chamber with a discharge orifice at, its apex and having in its base a plurality Vof ducts tangential to the- Wall of saidcharnber, and a cap to clamp the tip to the face of the nozzle.
