Claims.

directing cylinder and an external oil-fed flame chamber to which the oil is independently directed and which is under active control of pressure to direct the flame upwardly and beyond the burner proper.

A further object of the invention'is the provi-y sion of deectors by which the flame is directed beyond the burner proper in an` annular concentrated sheet or ring for electiveresult.

The invention is illustrated in the accompanying drawing, in which:

Figure l is a View in vertical section, partly in elevation, of the improved burner.

Figure 2 is a section on the line 2--2 of Figure l. The improved burner comprises an outer casing I, within which is arranged an inner casing 2, the bottom 3 of which is spaced from the bottom 4 ofv the outer casing. The outer casing is imperforate while the inner casing is perforated with holes of suitable size -throughout its full area except the 0 an exterior source and opening flush with the bot-v tom of the pilot chamber.- It is to be understood,

though'such parts are not illustrated, that conventional, for example, float controlled means are provided to control the delivery through the fuel 5 pipe 9 so as to maintain a comparatively shallow almost film-like accumulation of fuel in the bottom of the pilot chamber, as indicated at I0.

A ame directing cylinder I I is supported upon legs I0, resting on the bottom 3, the cylinder I'I 50 surrounding and in spaced relation to the pilot chamber. The legs II)a form a space between the bottom of the cylinder II and the bottom 3, to

form a slight passage between the space between the cup-shaped lreceptacle 8 and the space be- 55 tween the inner casing and cylinder Il. The

flame directing cylinder extendsfrom the bottom 3 of the inner chamber 2 to a point slightly below the upper ends of these chambers I and 2, and is provided at its upper end with bracket arms I2 which support a conical deflector I3, which may be radially'fluted. The deector extends within the flame directing cylinder with its apex I4 below the top of the cylinder, and in the upper edge of the cylinder, there is formeda series of cut-out sections I5 to establish more open relation be- 1 tween the space within the inner casing 2 and the flame directing cylinder.

The upper orfree edge I6 of the'deector I3 v fextends beyond the wall ofthe flame directing In the flame directing cylinder is ar- 15 cylinder.

ranged abaflle Il open at the center,l as at I8.

The flame burning chamber is included between the flame directing cylinder and the casing 2 and n' v is indicated at 20. The upper end of .this chaml ber 20 is provided with a baille plate 2 I--, preferably 20 secured upon the closed end 1 ofthe wallsof the inner and outer casing, which baille plate extends towards the, defiector I3, the central opening 22 of the baille 2| affording an outlet from the ame chamber 20 being arranged beneath the outer g5 portion of the deector. Thus all the flame passing out the opening 22, or as a. matter of fact, out of the flame directing vcylinder II is deflected by the def-lector I3 into an annular, comparatively narrow concentrated ring of'ame. 30

A fuel delivery pipe 23 extends into the flame chamber near the bottom thereof, the delivery of oil being controlled in accordance with requirements of heat, and hence it is contemplated that af conventional control valve, thermostatically governed, will admit the requisite quantity of fuel to the chamber 20 inaccordance with heatdemands. A conduit 24 leading from a source of air under pressure opens through the bottom 4 of the outer casing, so that the entire space between the inner and outer casings and within'the inner cas'- ing may be subjected to air under pressure. Of course, the motor or other means rfor supplying L air under pressure will be controlled bythe thermostatic element governingthe oilsupply tothe chamber 20. f y

As thus constructed, it will be understood that y there will be a very small quantity of loil or other dropped into! theoil in the pilot chamber. :As

the vapors from the oil in the pilot chamber rise in the name directing cylinder, they pass through the openings I5 into the flame chamberl 20, into wA which latter fuel is being admitted through the pipe 23. The air under pressure admitted through the conduit 24 will pass through the holes 5 creating a more or less vaporous condition of the oil in the chamber 2D, also through the passage lb to cause the ame from the oil in the pilot chamber to be forced into the chamber 2l), and at the same time upwardly through the flame directing cylinder and thereby heat the parts. The conversion action is so rapid that almost as soon as the air is turned on, the vapor in the name chamber is converted into flame with combustion continuously renewed from the fuel at the bottom of the chamber, and the flame and Vapor from the pilot chamber will be drawn upward into the ame directing chamber and forced through the openings I5.

The llame thus generated is directed outwardly through the opening 22 and deflected by the deflector i3, as previously described. The burner is constructed of metal, has no moving parts in itself and is designed to be inserted as a unit in a furnace or other enclosure according to the purposes-for which the heat from the flame beyond the deiiector is to be used.

In actual practice, there will be found no ame between the bame I1 and the fuel in the pilot chamber incident vto the pressure of air and the comparatively free upward movement of the same. However,when thermostatic control is effected and the fuel in the chamber 20 is exhausted, the flame in the upper portion. of the llame directing cylinder will gradually consume the vapor above the -pilot chamber and move downwardly until finally contacting and ignitlng the oil or other fuel in the pilot chamber, which fuel of course is maintained in constant supply.

The oil burner as a whole may be constructed the flame directing cylinder, means for directing fuel in constant limited supply to the pilot chamber, means for directing tuel to the space within the inner casing, and means for directing air under pressure to the space between the casings and through the holes in the wall of the inner casing.

2. A construction as defined in claim 1, in-

l cluding a baille near the lower end of the inner casing above the pilot chamber to restrict the outlet therefrom, and a conical deector carried by the flame directing cylinder and extending over the inner casing outlet.

3. A construction as defined in claim 1, wherein the flame directing cylinder is freely movable in the upper direction to permit access to the pilotchamber for igniting the fuel therein. 4. A construction as defined in claim 1,'wherein the iiame directing cylinder is interiorly provided with a baille and with an air passage below the baille and the flame burning chamber.

5. A construction as defined in claim 1, wherein the upper end of the flame directing cylinder carries a conical deflector which is radially convoluted. l
