FLAME DEFLECTOR FOR OIL BURNERS.

Application filed August 4, 1926. Serial 110.127,046.

This invention relates to an improved construction of flame deflector for furnaces; and has for its object to provide a flame deflecting member adapted to be secured in a furnace and against which the flame is forced, the deflector being shaped and positioned to upwardly deflect the flame directed against it, said defiector being lined with a refractory material capable of becoming 1ncandescent to act upon and better consume the fuel.

A further object of the invention is to form this flame delecting member in the shape of the flame with an elongated scoop or trough shaped body portion positioned to have its flame engaging surface upwardly inclined with a more sharply upwardly inclined discharge end portion for controlling the distribution of the flame directed against the device. A still further object of the invention is the placing between the dei'lector and the refractory material therein of a heat insulating material.

With these and other objects in view, the invention consists of certain novel features of construction, as Will be more fully described, and particularly pointed out iii the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation partly in section showing my improved flame deflecting member as positioned inside of a furnace.

Figure 2 is a plan view of my improved deflecting member.

Figure 3 is a central sectional elevation of the deflecting member.

Figure 4 is a section on line 4 4 of Figure 2 looking in the direction of the arrows; and showing the secur'ing flange thereon which closes this end.

Figure 5 is a section showing the securing bolts extending into the llanges and also showing a portion of the drain pipe as screwed into the end closing flange.

Tt is found in the operation of certain liquid fuel burning apparatus, or advantage to provide a spoon 'or trough-shaped deflecting member secured to the inside of a furnace and against which the burning charge is directed and to line this deflecting member with a refractor material so that the flame of the burning uel which impinges against it will heat this material to incandescence, thus serving to act upon and break up the oil particles to Abetter consume the same, the deflector being shaped to conform to the shape of the flame and positioned so as to direct properly the heat generated in the furnace to effect the most advantageous results. The following is a detailed description of the present embodiment of my invention and showing one construction of deflecting member by which these advantageous results may be accomplished With reference to the drawings, 10 designates the dellecting member which is formed more or less in a trough or scoop shape and which is open on its upper side, one end of the member being provided with a transverse flange or end wall 11 which extends laterally in both directions beyond the edges of the body portion of the member and the extending ends of the flange are provided with holes 12 for the reception of securing bolts 13 by which the device is bolted in position within the furnace.

This flange or end wall 11 also serves to close the lower end of the dellecting member and into this wall is tapped a drain pipe 14 which conducts unconsumed oil back to a drip bucket (not shown).

The body portion 15 of the deflector member is positioned to be slightly upwardly inclined, while the end portion of the body is curved more sharply upward to direct the flame as desired, about the inside of the furnace. The discharge end portion of this member flares laterally .to conform to the fan-shape of the flame and is much wider than the receiving end thereof also the side walls 17 at this extended discharge end are much higher than at the receiving end so as to better hold the flame until. after the fuel mixture has been consumed and then control its discharge against the walls of the furnace.

In order to protect the walls of this deflecting member against the direct action of the llame forced against itand prevent the deflector from radiating a large portion of heat, I first line the device with a heat-insulatin material as asbestos 18. then cover this lining with a thick layer of fireclay 19 or other suitable refractory material which is adapted to become luminous by action of the flame forced against it. This lining is locked in position by means of spurs or hook shaped members 20 against the walls of the device. y

My improved flame directing member is more or less of spoon-shape and serves as a firepot or mixing chamber for the burning fuel discharged against it and is so shaped and by becoming upon the surrounding walls of the furnace.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible. the invention being defined and limited only by the terms of the appended claims.

l claim:

1. A flame deiector for a liquid fuel burning apparatus comprising a spoonshaped body portion having a narrow inlet end and a-wide discharge end, said wide discharge end being sharply upwardly inclined, said body portion belng lined with refractory material.

2. A Hams defiector for burning a paratus comprising a spoonshaped bo y portion having a narrow inlet end and a wide discharge end,I said wide discharge end being sharply upwardly inclined, said body portion being lined with refractory material, and side walls extending from the inlet end to the discharge end, said side walls gradually increasingr in height from the inlet end to the discharge end.

a liquid fuel In testimony whereof I affixed my signature.
