oIL-BURfime APPARATUS Application filed July 21, 1928. Serial .No. 294,391.

v My invention relates to oil burning apparatus, of the type in which oil is supplied to a burner-head for combustion. I

The object of my invention is to provide a burner-head of simple andzcheap construction in which the oil and air may be supplied without any danger of forcing any oil from the burner-head chamber by air flowing therein under pressure.

A further object is to provide means for preventing carbon from being deposited on the upper side of the cap of the burner-head.

Referring to the drawings which form a part of this specification,

Fig. 1 is a plan view of a burner-head em.- bodying my invention. 1

Fig. 2 isan elevational side sectional view of the burner-head. I

Fig. 3 is a fragmental sectional view of a portion of the burner-head, shown on an enlarged scale. I

A, indicates a central cylindrical casting or. sheet metal conduit for air, which also serves to support an annular basin B, which may be 5 made of cast iron, and slipped upward over the hylinder A, before the joint A, is made with the laterally extending portion A of the conduit, for air.

An oil-tight joint 0, is made between the inner edge of the basin B, and the wall of the conduit with the top of conduit located on a horizontal line withthe top edge of the basin, as shown.

A V shaped recess D, is formed in the bottom of the basin between the outer' wall of the conduit and the inner bottom end portion of the basin, and a circular porous wick E, of heat refractory material, rests in said recess. and'is rovided with a conically shaped lower sur ace E which abuts the inclined surface E formed on the inner side of the basin as shown. The basin B, is formed with a, boss F, having a passageF' leading to the wick E, and a pipeH, leading to the passage to conduct oil to the wick.

The basin is formed with a shallow annular depression G, which serves to hold. any oil which overflows from the wick, the lowest portion of said depression being located directly under the outer'edge I of the cap I,

the deflecting ring which edge is positioned approximately mid-' way between the upper end of the conduit A, and the outer rim B,-pf-thei chamber B.

Just below the top end A of the conduitA, a circular outwardly extendin flange A is. formed integral with'th'e conduit, a'nd'a circu; lar air deflecting ring J, is supported thereo in removable'relation therewith.

- A three legged bracket K, shaped as shown, rests on the top edge of the conduit A, in freelyremovable relation thereto, and is provided with a boss K, having a threaded hole K extending therethru. 'A threaded rod L, extends thru said boss and supports the cap I, and an inner shield M, spaced apart from each other by the washer N, and are held together by the two nuts OO respectively.

The cap and shield are semi-spherical in form, as shown.

The cap and shield areadjustable relative to the basin B, as will be readily understood.

The wick E, may be made in two; or more portions so that a new wick may be inserted without difliculty.

The device operates as follows:

Oil is maintained on a level with the upper side of the wick E, by supply means not shown herein. I

Air under pressure flows thru the conduit A, between the legs of the bracket K. and is deflected downwardl by the shield M, over J into the bottom G, of the basin B, and mixes with thepil vapor generated by he heat reflected from the burning fuel in the fire box and upper side of the basin, in which, the burner-head is located in the usual position.

The space between the cap Land shield M,

serves to .prevent chilling of the cap, which would cause oil vapor to condense on the upper side thereof, and earbonize.

The air being deflected downwardly and outwardly, strikes the lower part of the basin at the outer rim of the depression formed therein, and does not lift the oil bodily therefrom, but mixes with the oil and vapor which flow, together from the basin and burn freely im the combustion chamber. f

This arrangement of the burner parts,- overcomes the trouble caused by air hfting the oil bodily from the bottom of the basin, which was one of the defects of my earlier burner-head.

The parts of the burner-head are so assembled, that they may be easily disassembled for cleaning or repairs, as will be clearly understood from the drawings.

Having thus described my invention, I

claim as new:

1. A burner-head of the character described comprising a conduit for air, a basin supported by said conduit, a wick in said basin, means for leading oil to said wick, a cap supported above the upper end of said conduit adapted to deflect air into said basin, and a ring for deflecting air mounted on said conduit below said cap.

2. A burner-head of the character described comprising a conduit for air. a basin supported by said conduit, a wick in said basin, said basin having a passage for oil leading to said wick; a cap and a shield spaced therefrom, supported above the upper end of said conduit and adapted to deflect air into said basin.

3. A burner-head of the character described comprising a cylindrical conduit for air, an annular basin supported thereby, a wick in said basin, means for leading oil to said wick, a cap and shield open .to the atmosphere at their undersides and held together in spaced relation and supported above the upper end of said conduit and adapted to deflect air into said basin.

4. A burner-head of the character described comprising a circular conduit for air, an annular basin mounted thereon having a passage for oil formed therein, and a V-sh'aped recess formed in the bottom thereof,

a wick in said recess iii open communication with said passage for oil, a dome shaped cap open at its under side to the atmosphere and supported by said conduit above the upper end thereof the rim of which is positioned above the middle of the basin.

5. As stated in claim 1, together with a ring mounted on the conduit for deflecting air to the middle of the basin.

6. As stated in claim 4, together with a dome shaped shield open to the atmosphere on its under side and held in spaced relation with the cap.

7. As stated in claim 3; said shield and cap being freely removable from said conduit and adjustable relative thereto.

In testimony whereof I have affixed my signature.

ALBERT- E. GRANT.
