v Y' 'Y The invention .relatestoiiniprovements in` vention to provide a new and improved vform y of burner'particularly adapted` vfor use in burners of' the general"y type in Vwhich liquid fuel is -volatilized, mixed withair and dis-Y charged' through perforations. L I

Figure 6 is a central longitudinal section "on the plane'of lined-6 of Fig. 5.

(See Fig. 6).l is horizontally divided as indicatedvat 12, providingit with anrupper section 13 which may readily be then giving access to partswithin the body for cleaning them also. VThe lower section ofthe body 7 is by preference provided with suitable Y integral supports'li, and an-air supply manifold 115 which extends longitudinallyV below tion. Y

the body,""rnay well'l be i integrallyconnected with oneof these supports',v This manifold,

`in 'the-:present disclosure, is provided .-with Y a pluralityof upstanding lbranches 16. which open through thelbott'om 11 Vat longitudinally Ispaced I points, and to. prevent' the outflow is provided around them, with upstanding lr1dges-.17. 11

. A; perforated fuel-,pipe lll-islniounted longitudinally within the central porti-on of the ofi fuel through these branches, said bottom Y Y :body 7, said pipe being preferably supported .f

uponv suitablek saddles 19 formed .integrally with thel bottoin 1-1. A fue-lj line y 2,0 4leads v to the pipeflS, preferably vfrom 'anelevated tank 21 andthis line may berprovided both v with "a cutoff valve 22 and v,with a How- Collier -trol valve 23;. 'fo-overcome thiefy possibilityV of any ioil from. the pipe 1,8, runningyinto the manifold 1 5,;through its-biganches1-16,

suitable shields 24 are preferably-providedr over-said branches. These shields may well Contact with 'the lower'side' of the pipe 18, some of them may be secured directly to this pipe as indicatedv at 25, whileanother mayv be supported on aportion of the fuel line 20, by a nut or the like 26.` i .y

'In' operation, the valve 22 is Vopened to permit the discharge of oil from VVthe pipe 18 y into vthe body 7, until a sufiicientrquantity of. such oil has. entered the trough 9through the openings 10 for pre-heating purposes, f

sufficiently heatedfto effect vaporization of the fuel whensthe supply fis again' turned on.V

The fuel is thenjignited in thetrough'and by Y I l i i fthetime, it is'consuined, the body 7 has been 90 i l Consequently,upon/openingof the valve 22, the discharge of fuel from thepipe 18 strikes the hotmetal, becomes immediately gasiiied, mixes thoroughly with air entering through the manifold 15, and'discharges i.

through the per-forations 8fto produce a hot flame. The intensity of this flame is of' cours'eto be controlled 'byregulation ofthe `lVhenever cleaning of the burner is necessary, the valveV 22,` may be closed and the z upper l section 13 of the body V7 detached; Them'not only canpthisseetion Vbe readily cleaned, but vaccess is had tothe pipe 18 and associated parts, soY that theyA also maybe" i effe'ctively'freed of any;l foreign accumula-- .Y

` Theinvention, it be l-lobserved,"'isre ii. ceptionally simple and inexpensive, yet `will Hof:

be sulficient`,reliable andn'in every waydesir'- able. On accountof the advantages existing Vfor the'details'disclosed, they are preferably that variations may be made. For instance,

instead of having the burner body and contained fuel pipe of straight form, they might well be of other shapes, such as that shown in my companion U. S. application Ser. No. 106,760, filed May4, 1926.

VI claim: n V1. A liquid fuel burner comprising a horizontally elongated hollow tube-like body having a perforated upper portion and having its lower portion pr'ovided'with an outstanding drip and pre-heating trough, saidV body having one or more perforations near its bottom for Adischarging fuel into said trough for pre-heating purposes, a perforated fuel pipe mounted in and 'extending longitudinally of said body above its bottom, fuel supply means leadingto saidpipe, air inlet means through the-bottom of said body,

Vand guard means around'said air inlet Vmeans to 'preventoutflow of fueltherethrough.

2. A liquid fuel burner comprising a horizontally elongated hollow tube-like body having a perforated upper portion and'havsaid branches from said pipe.

ing its lower portion provided withwan outstanding drip and pre-heating trough, said body having one or more perforations near its bottom for discharging fuel into said trough for pre-heating purposes, a perforated fuel pipe `mounted in and extending longitudinally of said body above its bottom, fuel supply means leading to said pipe, and an air supply manifold under said body having upstandingbranches discharging at spaced points through the bottom of said body, said bottom having ridgesaround said branches to prevent outfiowV of fuel therethrough; Y Y

3. A. structure as specified in claim l; said body vbeing horizontally divided to 'provide an upper section removable *for cleaning pur poses, said trough being formed by a continuous flange integral with theV lower section of the body.

el. iti structure as specified "in .claiml 2;

together with guards supported at the lower` rside of said fuel pipeV and extending over said branches to prevent descent ofyoil lnV testimony whereof I aixed my signature.
