OIL-GAS BURNER.

Specification of Letters Patent.

Patonted flet. 17, 1911.

Application filed March 16, 1911. Serial No. 614,856.

vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in oil gas burners.

One object of the invention is to improve the construction of the burner shown in United States Patent, No. 956,114, granted to me April 26, 1910, whereby the eiiiciency or heating capacity of the same is greatly increased, and the oil feeding and vaporizing mechanism improved.

With this and other objects in view, the invention consists of certain novel features of construction,combination and arrange ment of parts will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings :F igure 1 is a side view of my improved burner; Fig. 2 is a top plan view; Fig. 3 is a central vertical section of the same; Fig. 4C is a side view of the inner oil deflecting cone; Fig. 5 is a central vertical sectional view of the outer deflecting cone; Fig. 6 is a similar view of the flame spreader removed from the burner; Fig. 7 is a plan view of a double l burn er.

Iuthe ,cmbodiment of the invention I pro vide an inner base member 1 which is preferably in the form" of a circular bowl having ,its side walls preferably inclined inwardly toward the lower end. of the bowl as shown. In the bottom 2 of the bowl is formed a centrally disposed draft opening 3. In the bottom of the bowl around the opening 3 is formed an annular drip .or

drain channel 41 adapted to catch the over-,

flow oil. The base 1 serves to confine a part of the heat of the burner which vapor izes the .oil and causes the same to mix with the air and thus form a highly combustible and economical gas. I

Arranged in the base and adapted to be engaged with the bottom 2 over the opening 3 is an inner oil deflecting cone 5' havlng on its lower-edge an annular flange 6 and in its sides a series of vertically dis-' posed elongated air passages 7. A ound the side and top edges of the passages 7 are termed outwardly projecting flanges S. The spaces between the side thinges 8 form inclined grooves or channels in the upper end of the cone 5 is formed a threaded. feed opening with which is engaged the threaded end of the oil feed pipe 10, said pipe passing up through the opening 2 in the bottom and through the come as shown.

Arranged over the inner cone is an outer cone 11 said outer cone having on its inner side a series of spacing ribs 12 which are adapted to engage the grooves 9'botween the flanges 8 on the inner cone thereby spacing said cones the proper distance apart. In the sides of the cone 11 between the ribs 12 are formed passages 13 which register with the passages 7 in the innercone. 'The passages 13 are divided centrally by longi tudinal ribs 14; which project inwardly to a slight extent as shown. \Vith the upper end of the outer cone 11 is engaged a flame spreader 15 which is preferably in the form of a concaved or saucer shaped circular plate. The spreader plate 15 is of less diameter than thebase 1 and is disposed immediately above the upper end of the same as shown. By thus arranging the spreader the flame will be deflected and directed against the sides of the fire box of the stove in which the burner is arranged.

In Fig. 7 of the drawing is shown a double arrangement of burner adapted particularly for use in fire boxes'of cooking stoves. In this form of the device two small burners are secured to a rectangular base plate 16 in such position that one of the burners will be below each of the openings in the to a of the stove over the fire box, when the base plate it) rests on the grate of the box.

In the operation ol the burner the oit is discharged from the feed pipe between the fit upper portions'of the two cones and flows downwardly in the grooves or-channels 9 in the inner cone 5 and around the ribs and flanges on said-cones and is vaporized by Contact with these parts when the same become heated. The flame from the oil and gas formedby vaporized oil and air burns through the r passages 13 in the outer cone and blazesup out of the upper end of the base. The flame is deflected when leaving the base by the spreader 15 as hereinbefore described and the heating capacity of the burner thus greatly increased.

13y arrangil'ig the oil feed pipe as herein shown and described the discharge end of the same is not exposed to the flame and therefore will not become carbonized by the of this invention as defined in the appended claims.

l-Iavin g thus described my invention, What I claim is:

1. In an oil gas burner a bowl shaped base having in its bottom a central draft opening, and an annular groove, an inner burner section arranged in said bowl over the opening therein, said inner section having therein a series of openings and a series of oil feeding grooves, an oil supply pipe arranged in and opening through said inner section, an outer section having formed therein a series of openings adapted to co incide with the'openings in the inner sections, longitudinal dividing ribs arranged in said openings in the outer section, and a series of ribs formed on the inner side of the outer section and adapted to engage the oil feeding grooves in said inner section.

2. Tn an oil gas burner a bowl shaped base having in its bottom a central draft opening, and an annular giwsove. an inner burner section arranged in said bowl over {the opening therein, said inner section having therein a series of openings and a series of oil feeding grooves. an oil supply pipe arranged in and opening through said inner section, an outer section having formed therein a series of openings adapted to coincide with the openings in the inner section, longitudinal dividing ribs arranged in said openings in the outer section, a series of ribs formed on the inner side of the cuter section and adapted to engage the oil feeding passages in the inner section and a concaved spreader plate reinovably engaged with and supported on said outer cone.

In testimony .whereof I have hereunto set my hand in presence of two subscribing Witnesses.
