OIL BURNER.

/ Specification of Letters latent;

Application filed November 27, 1909. Serial No. 530,151.

To all whom it may concern:

Be it known that I, HUGH L. BRALY, citizen of the United States, residing at Clarendon, in the county of Donley: and State of Texas, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification.

My invention relates to devices for burning oil in stoves or furnaces and particularly to a construction adapted to be placed to a position within a stove above the grate surface thereof, providing a hearth or stove on which the oil is to be burned, and means for permitting a proper inlet of air to the fire generated on the hearth.

The invention consists in the arrangement of parts and details of construction set forth in the accompanying specification and more particularly stated in the claims appended.

For a full understanding of. the invention reference is to be had to the following description and accompanying drawing, in which 2- V f Figure l is a sectional view of a stove showing my improved burner in section? Fig. 2 is an enlarged section through the. air chamber of'thebu rner. Fig. 3'i's a per-' spective View of the burner detached "from the stove. Fig. t is a like view to Fig. '1 showing a modified form of'burner.

Corresponding and like parts are referred to in the following description and indicated in all the views ,of' the accompanying drawing by the same reference characters.

Referring to these figures A designates a stove or firebox of any desired character, and B the grate thereof.

One form of my invention comprises a.

burner adapted to be inserted within thestove or firebox and to be placed on the top of the grate 13 therein. This burner is preferably made of onepiece of refractory;material such as fire brick, the pipes} for con'-' ducting the oil to the burner being of course inserted therein after it 'is. manufactured.-

This form of in invention is shown in Fi s.

. a b r 1 to l. H p 2 designates a body of refractory material, such as above described, having on one side thereof the burning trough or hearth 8. The bottom 4 of this hearth inclines toward the body 2 from the side edge of the hearth, and',is also inclined from the middle towardthe endsthereofso that the oil on the hearth may be evenly distributed. Formed in the body 2 and extending longitudinally therealong is the air chamher 5 which opens at the bottom of the'body and extendsover the grateB of the stove. This air chamber is connected to the hearth 3 by a plurality of slot-like openings 6, whereby airmay be introduced along the whole face of the wall 7 of the body 2. To

provid for the introduction of oil to the burner, I form the body 2: with the oil passage 8 which extends inward from the face of the wall 7 and which may extend either directly through the body portion 2 orextend to the middle of the b( dy portionand then downward, as shown in Fig. 4. The interior of this passage is screw-threaded for engagementwith an oil pipe 10 which extends out of the stove or firebox, and is connected to any suitable oil reservoir.

' This .pipe is of course provided with suitable valves wherebythe amount of oil flowing' through the pipe may be regulated or checked entirely. In order to prevent the flames from the burning oil" onjthe hearth 3 from igniting the'oil as it passes out of the inlet passage-8 I provide on each side of the inlet'passage, air passages 11 whichjcommunicateat their. inner ends withtheair chamber .5. Thus the flow of airout of said airpassages 11 will force the fiames away from-the .oil flowing out of the inlet 8 and thus prevent the ignition of'said oil.

the lower end'of the air chamber and thus prevent the passage of (air up through the Patented Jan. 23,1912.

so'i V f 1 The operation of my invention is obvious; :The burnerjis placed. upon the grate B and t thoroughly embedded in mortar D, care be 9. ing. taken" not to allow the mortar to'cover grate B and to the hearth. When the 'oil is lighted, the; air passing to the hearth through the series 'of'horizontal slots 6 in troduces.into'the blaze suflicient air for the proper combustion of the oil, while the 7 smoke from the burning oil passes out f through the chimney of the stove box in the usual manner. A I v p The formof my invention shown in Fig.4 7 f is practically the same as that prviousl'ydef ioof.

scribed except that the oil feed pipe passes upward through the grate B instead of passing in through the side .of-thefi-re box or stove. In Fig. 4:, 2 designates the body of the burner of .refractorymaterial having a hearth 3 fand the air chamber 5*. The air chamber is connected to the hearth by ,Iaplurality ofslot-like openings as previously described. The oil passage 8 is connected to an oil pipe 10 which extends up through the grate of the stove and through the air chamber 5, the outer end of the passage 8 being closed by a plug 9 The operation of this form is precisely the same as that previously described.

My invention is simple, easily placed in position and thoroughly effective in practiee. There are no complicated parts to clog and the body of refractory material which forms my burner retains and conducts suiiicient heat to vaporize even crude oil so that it may be more readily burned.

Having thus described the invention what is claimed as new is 1. In an oil burner, a hollow body of re fraetory material open on its under side for its entire length and adapted to rest upon the grate of a stove, said body having a hearth projecting out laterally therefrom at the base of the body, an oil supply duct extending through the interior of the hollow body and opening upon the face of the body above the hearth, and an air supply duct spaced from the oil supply duct and communicating with the hollow interior of the body, said duet also opening upon the face of the hearth adjacent to the opening of the oil supply duct, said body being further provided with a plurality of air openings disposed on either side of the opening of the oil supply duct and extending along the wall of the hollow body above the bottom of the hearth.

In an 011 burner, a hollow body of refractory material rectangular in section and open on its under side and adapted to rest upon the grate of a stove, said body having a hearth projecting out laterally therefrom at its base, the ends of said hearth having upwardly extending walls joining the body, an oil supply duet extending through the interior of the hollow body and opening upon the face of the body above the hearth,

air supply ducts disposed one on either side of the oil duct and communicating with the hollow interior of the body and so arranged as to direct a blast of air outwardly to drive the flames away from the face of the body and away from the oil duct, and a plurality of air openings disposed on each side of the oil duct, but below the same and extending along the face of the body and communicating with the hollow interior thereof.
