H. STRAUTMAN ET AL OIL BURNER Filed Sept. 30, 1940 NIR Patented Mar. 17,- 1942 UNITED STATES PATENT OFFICE y OIL BURNER Henry Strautman and Karl Jauch, St. Louis, Mo.

Application September 30, 1940, Serial No. 358,949

1 Claim.

This invention relates to improvements in oil burners specially designed and constructed for domestic use and for placing a burner in a fur nace for homes and like structures.

The object of the burner is to provide for a regulated supply of fuel, with a means for igniting the same, and for heating a coil of air under pressure for intermingling with the vapor arising from the oil which when in ignition will cause a clean, fully consuming flame with in? tense heating units.

Another object is the general arrangement, construction and combination of parts as will be fully hereinafter described and set forth in the claim,

This invention is an improvement'l over applicants former Letters Patent issued to them June l5, 1926, and numbered 1,589,262.

Referring to the drawing:

Figure 1 is a side elevation of a furnace with a part thereof broken away, showing our burner in position therein.

Figure 2 is a Vertical central sectional View of the burner.

Figure 3 is a top plan view of the same.

Figure 4 is a horizontal sectional View of the burner taken on the line 4 4 of Figure 2, and viewing the same in the direction indicated by the arrow.

In the drawing, 5 indicates an ordinary furnace such as is usually used in residences, and in said furnace is the usual re box 6 all of which is not new nor do we claim the same.

In the rebox 6 we place our improved burner which consists of a cylindrical body member I a portion thereof being hollowed out and at its bottom tapering in to a conical cavity 8. In the wall of the body member and at the commencemeni; of the conical cavity is formed pref' erably a V shaped gutter or channel 9 which is for the reception of oil supply fed thereto by the supply pipe III connected to the usual supply tank and controlled by a valve II.

The upper ends of the cylindrical body member is provided with a contracted opening I2 its inwardly upper flared portion being provided with a plurality of elongated openings I3 through which the ame and heat pass and flare outwardly, and above the contracted opening is located a coil of piping I4 through which air under pressure is directed downwardly through a central extension I5 and terminating close to the bottom of the V shaped cavity 8.

The air under pressure is heated by the flames grounded through and this heated air is directed through the it mixes with the air and when ignited causes a l perfect bluish name of intense heat units.

On the pipe I5 is placed one member of an ignition unit I'I having electrodes I8, this unit is the furnace body, while through the wall of the cylindrical body member is passed ignition members I9 having electrodes 20, these members being insulated from the body member and lits leads connected to the general spark producing mechanism which will create a spark between the electrodes which spark has a tendency to ignite the oil spray which is permitted to form above the top of the pipes ZI which are fed with oil from any supply and permitted tospray only when starting the burner in action.

This device acts as a lighter and does not flow continuously, only when lighting the burner.

Some and other changes may be made in the construction and arrangement of the invention above set forth without departing from the real spirit and purpose thereof; and it is our intention to cover by the following claim equivalents which may be reasonably included within its scope.

We claim:

In a burner of the character described, a cylindrical body member having a contracted upper inwardly flared opening and a conical shaped bottom cavity, escape ports formed in the sides of the contracted opening, an air coil located on the top of the contracted opening with a vertical pipe portion of said coil extending downwardly into the conical shaped cavity and terminating in an air nozzle, an ignition means carried by the pipe portion of the coil, ignition means carried by the body member and registering with the ignition means on the pipe, vertical positioned ignition fuel supply pipes located Vin the body member with their openings positioned relatively near the ignition members for permitting igniting of the ignition oil as it sprays from the pipes, and an oil supporting channel formed in the body member adjacent the Vertical fuel pipes for ignition therefrom and into which oil is fed from a suitable source of supply.
