ort-nomma Specification of Letters Patent.

Patented Mar. 14, 1916.

Application filed J une 22, 1915. Serial No. 35,556.

To all whom it may concern:

Be it known that l, FRANK E. NELSON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Oil-Burners, of which the following is a specification. n

My present invention pertains to oil or liquid-fuel burners such as are designed to be inserted in the tire boxes of stoves and ranges; and it contemplates the provision of a burner, of the type stated, embodying such a construction and relative arrangement of parts that heated air is supplied both .above and below the body of ame with a view to promoting combustion.

The invention also contemplates the provision in a burner of the kind stated of iinproved means for regulatingthe volume of air supplied to the burning oil.

Other advantageous featuresof the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, acco-mpanying and forming part of this specification, in which: c

Figure 1 is a side elevation of my 1inproved burner. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is an elevation of the outer end of the burner. Fig. 4 is a transverse section taken in the plane indicated by the line 4-'4 of Fig. 2. Fig. 5 is an enlarged detail section.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The hollow body 1 of theA burner is provided at its forward end and in 'its bottom with an opening 12 for the entry of air, and at its otiter or rear end the said body 1 merges into an enlargement 2 havinganexterior flange 3, designed to bring up against the outer side of a stove or range wall. The said portion 2 is equipped with an 1nclined removable door 4, and on said door are handles 5 for the convenient manipula.- tion thereof. In the door are two (more or less) slots 7 which receive bolts 6. The said bolts serve for the adjustable connection of the controller 8 and are preferably, though not necessarily, equipped with wing-nuts as shown. It.will also be noticed, by reference to Fig. 2, that the enlarged portion of the body is provided with an opening 9 for the introduction of oil and that the upper portion of the inner end of the enlargement is open, while the to-p of the body 1 adjacent to the said opening is slightly inclined l[doviiwardly and outwardly as indicated Slidably-arranged in the enlarged portion 2 of the body is the oil pan 11. The supports of the said pan bear on the bottom of the body 1 and hence it 'will be manifest that the pan can be adjusted relative to the body portion 10 to increase or-diminish the vclume of air supplied below the burning oi 1t will also be manifest that by adjusting the pan relative to the controller 8, the volume of air supplied above the burningoil may be regulated, and this latter regulation may be further carried out by raising or lowering the controller 8 and adjustably fixing the same with respect'to the door 4.

After the burner is placed in operation the body l will be highly heated, and from this it follows that the air that enters the opening 12 will be heated to a considerable extent en route to the points at which such air is commingled with the burning oil. rThis supply of heated air under and over and up in front of the Hamesinduces and supportsperfect combustion, and the pro er combustion is further promoted bythe act that heated air is suppliedto the burning hydro-carbon.

It will further be manifest from the foregoing that when the-door 4 is removed access may be gained to the oil pan 11 either to adjust the said oil pan or to remove the same for cleaning or for any other purpose.

The capacity of adjustment of the oil pan 11` and the controller 8 will be appreciated as important features of my invention when itis stated that drafts are so variable and difficult to contend with that perfect combustion cannot be obtained unless eflicient means is provided for increasing or diminishingjthe volume of air supplied to the burning oil as occasion demands.

In order to use cool air with a `view to preventing deterioration of the metal by the high heat, I prefer to' provide the door 4 with a narrow horizontal slot 13 and narrow Vertical slots 14, relatively arranged as shown in Fig. 3; and l also prefer to provide narrow spaces between the ends of the controller 8 andthe end walls of the body enlargement 2. Thus the air that enters through the slots 13 and 14 prevents the heat from injuring the metal ofthe body, but does not materially cool the air supplied through the opening 12 and the forward portion of the body 1, and by reason of the latter air being permitted to pass between the ends of the controller 8 and the end walls of the body'portion 2 it will be s'een that the llame is completely surrounded by heated air.

The oil supply pipe 15 is preferably provided with a valve 16fixed to one end of the body portion 2, and the discharge end of said pipe 15 is preferably s aced above izihe opening 9, Fig. 3 so as to a ord a sight eed. i

When desired the bottom of the body portion 2 may be slightly inclined downwardly and rearwardly, Figs. 1 and 2, and may be provided at the lowermost point with a drain 17 for the safe escape of such oil as may overliow or drip from the pan 1-1.

One of the air spaces at the ends of the controller 8 is clearly shown in Fig. 5.

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

1. An oil burner comprising a hollow body having an opening in the forward portion of its bottom and also having an enlargement at its outer end; the upper portion of the inner end of said enlargement being open, and the top of the body being extended outwardly and downwardly beyond saidy opening, an inclined door arranged on the enlargement of the body, a controller adjustably connected with and extending downwardly and inwardly froml said door, an oil pan adjustable in the enlarged portion of the body and relative to the said inclined wall portion of the body and the controller, and means for supplying liquid fuel to Said pan.

2. In an oil burner, the combination with a hollow body having a forwardly extending conduit for the entry of air and also having a forwardly disposed opening for the passage of flames, a controller arranged in the body back of said opening, and an oil pan arranged in the body and under and spaced from said controller and above and in rear lof and spaced from said conduit,whereby largement and an opening in the upper portion of the forward end of the said enlargement for the passage of flame, an oil pan arranged in said enlargement of the body, supports for said pan slidably-arranged on the bottom of the body, and means in the body for coperating with the pan to form a conduit to carry air toa point above liquid fuel burning in the pan.

4.. In an oil burner, the combination of a hollow body having a forwardly-extending conduit for the entry of airand also having a forwardly-directed opening'above the rear portion of said conduit for the passage of flames and further having air-induction means in its rea'r wall, a controller arranged in the body with its ends spaced from the ends or sides of the rear portion of the body, and an oil pan arranged in the body and interposed between and spaced from said conduit and controller, whereby the flame of burning oil in the pan is entirely surrounded by heated air and at the same time cool air is admitted to prevent injury to the metal.

5. In an oil burner, the combination of a hollow body having a conduit for the entry of air and also having a forwardly-directed opening above the rear portion of said conduit for the passage of lames,'a controller arranged .in the rear portion of the body with its ends spaced from the ends of the body, and an oil pan in the body and interposed between and spaced-from said conduit and controller, whereby heated air is supplied to the flame of burning il in the pan above, below and at the sid`es of the llame.

6, An oil burner, comprising a hollow body having a forwardly-disposed opening for the passage of flames and also having openings in its back wall, an oil pan arranged in the body, a controller back of the oil pan and spaced at its ends from the walls of the body and forming with the pau a conduit for supplying air above the pan, and means coperating with the oil pan to form a conduit to supply air forwardly below the pan and the flame.

In testimony whereof I have hereunto set my'hand in presence of two subscribing witnesses.

FRANK E. NELSON.
