FUEL-OIL BURNER.

Specification of Letters Patent.

Patented Aug. 27, 1918.

Application filed April 8, 1918. Serial No. 227,163.

To all whom it may concern.'

Be it known that I, CHARLES HARVEY, a citizen pf the United States, residing atl Somerville, in the county of Middlesex and State of Massachusetts, have invented new and useful Im rovements in Fuel-Oil Burners, of' which t e following is a speriication.

This invention relates to fuel "oil burners, and has for its object to provide an oil burner adapted to vaporize fuel oil and 'utilize the same for cooking and heating purposes, a particular object of the invention being to provide a simple, strong and durable apparatus, -free from liability to be warped or distorted by heat, and adapted- `to operate without objectionable noise.

The invention is embodied inthe improve- `ments which I will now proceed to describe and claim.

Of the accompanying drawings forming a part of thisspecificatiom- Figure l is iside eleyation"ofenapparatus embodying the inveitioll'f-Oneenjoris u qunglty 0 oilis supphed'to the base, Preftion ofthe apparatsmbei'g" removed.. I

Figa 2 is' a section on line 2 2 of Fig. 1.

Fig'f?) is an end view of the apparatus, a

portion being broken away. c

Fig.4 isa section on line 1 -4 of Fig. 3,

' Fig. 5 is a section on line 5-5 of Fig. 1. Fig. 6 is a section on line 6-6 of Fig. 1. Fig. 7 is a view similar to ay portion of Fi 4, showing a modification.

he same reference characters indicate thesama. parts ,i1 1 al1 Qf the figures- The apparatus includ'e`s"a"base formattato contain a shallow body of oil to .supply preliminary heat, said' base comprising a horizontal bottom 12v anda marginal curb 13, projecting upwardly from the bottom,

- saidbottom and curb forming portions of a shallow open-tankor trough, adapted to y contain alimited quantity of oil.

The Abase is provided with seats-14 which Fare preferably flush with the upper edge of thecurb 13, and are adapted to support and ibo rdetachably secured to the angularmemstandard being tubular. The bore 17 is closed adjacent to the standard 16, as shown by Fig. ,and the standard 16 is solid and serves only as a support for one end of the retort. The standards 15 and 16 are attached to theseats 14 by bolts 18, as indicated by Figs. 5 and 6, said bolts passing through the seats and through slotted ears 19dformed on the lower ends of the standar s.

20 represents an oil supply pipe, communicating with the lower end of the bore of the tubular standard 15.

A gas or vapor conduit having a vertical portion 21 and a horizontal portion'22, commmimjgates with the retort near thev closed end thereoftherertical portion 21 being con nected with a nipple..23 formed, on the-retort, while the portion 22 Kextends under and parallel with the retort, and is provided with a gas outlet 24: arranged to directa flame upwardly against fthe flame spreader 25 formed on the under side of the retort.

Before o rating the apparatus, a suitable continuously heat, not only theretort 17, butthetnbular standard 15 and the vertical portion 21`of\the gas conduit. The heating of the standard 15"a`nd the gas con: duit by the vapor flame `is dueto the fact that said standard and the conduipqrtion 21 are located at opposite sides of the burner outlet and in relatively close proximity thereto, so that each receives heat from the laterally spread ox-.deiected llame.

The angular forrnof the-member which includes the standards `15 and 16, and the retort`17, and the attachmentof the lower end of eac'h standard to the base, prevents any possibility of ldistortion of the said member, and" isplacement of the retort por# tion thereof, by heat, the retort being, therefore, maintained irrea horizontal position and at the exact height desired above` the gas outlet 24.

vaporizes oil standing tubular nipple The bottom 12 is provided with an up- 27, projecting through the oil confining space on the base, and constituting an inner oil curb surrounded by the marginal curb 13, and also constituting an air conduit extending through and lateral displacement of said portion, so that the gas outlet 24 is maintained 1na central position relatively to the spreader 25 and to the nipple 27.

It will now be seen that a ame directed upwardly from the gas outlet v24 induces an upward How of air currents through the passages 29, theair mingling with the Haine.

The upper end of the nipple 27 constitutes a seat on which is detachably mounted a noise-reducing hollow cap, whichfincludes a tubular body ory wall portion,30,;constitut ing an extension of the nipple 27; and provided with air i at the upper en of t e bodyJv-and provided with a contracted central -passage for .the

flame and air mi'xedtherewith. The. lower end of the body is o en, "toreceive the up "pei-en .dt of the lnipp e 27,"and is provided witlrii4 or anges 34 which f bearo n the seat for'fn d bythe upper end ofsald` nlp le.

The tube or paage 33 is-arrangedso t at the flame passes centrally .through 1t. The

said cappr nip le extension not only pre-.`

vents o 'ectiona 1 e` noise whernthe burner is operating, `but also-prevents liability of accidental extinguishment-of. the flame. The extension is separablyengaged with the nipple to permit convenient access to the vgas outlet 24, in case it is necessary ,to remove an obstruction from the outlet. The base may be supported bya supplemental base V35, formed to bear on the grate of a vfire-bpx, and open to permit air to ass upwardly through the tubular wall 27. he burn r ,when used in a stove or range having an o ong fire-box is preferably-corres ond-`- ingly formed, and made in two du icate units arranged in tandem'order as in by Figs.' 1 and 4,-the standardiportions 16 bein 1n closef proximity to each other, and attac ed to thecentral portion o f the base, which is made of suliicient len h to support the two units. The elongate base may be divisible at a point between the standard.

portionsl 16, to convert the structure into two independent, relatively short' burners.

To this end the marginal curb 13 may include two transverse portions 13 (Fig. 4), at opposite sides of a narrow portion 12 of assa es 31, and' a head 32 Standards `attac icated the bottom, said portion constituting u severable neck between two operative base portions, so that by sawing through, or otherwise severing said neck, two com lete burners may be produced, each inc uding elements such as the supply pipe 20, the angular member 15, 16, `17and the gas conduit 21, 22, constituting an independent oil vaporizing and burning unit, adapted to operate as hereinbefore described. =If desired, the base may be formed in two sections, abutted together, end to end, and -separably connected by bolts 37, or otherv suitable fastenings, as shown by Fig. 7, each section including a bottom portion 12b and a continuous marginal curb 13", adapted to confine oil upon the bottom portion.

The channeled rest 28 constitutes a gutter,

adapted to conduct oil,.` escaping from the outlet 24 to the oil-containing ortion of the base, said rest beingvpreferaby inclined as shown by. Fig. 4, so that oil flows toward one end of the rest.4 Provision is thus made for preventing oil from fallingthrough the air -conduit formed by4 ythe nipple` 27.

spaced upright portions constituting Standards attached at their lower ends t0 the base, and a substantially horizontal tubular intermediate portion constituting a retort and provided at its under side with a. flame spreader, means being provided for admitting oil at one end portion of said retort, and a gasconduit communicatingwith the opposite end portion of the retort and provided with a gas outlet arranged to project va flalneu awardly against said spreader, the

angular ornji of said member and the attachment of its upright portions to the base preventingr distortion of the member and displacement of the retort and spreader relatively to the gas outlet by heat.

In testimony whereof I have aflixed my signature.`
