. OIL BURNER.

Application filed July 12,

This invention relates to oil burners of the gravity feedtype and is adapted-particularly for burning heavy flowing oils such as crude oil, fuel oil or the oil drained from the crank cases of automobiles or other cheap forms of liquid fuel. 1

An object of the invention is to provide a base having an oil pan formed therein and having the burner mounted above the base and arranged with respect thereto whereby to form an air draft between the base and the burner whereby to facilitate the operation of the device. I

A further object is to form a drip flange about the burner and in aposition to direct the overflow from the orifices formed in the burner whereby to deposit any excess of oil to the drip pan.

Another object is to provide an article of this character of simple and practical construction, efficient and reliable in performance, economical in consumption of fuel, and adapted to use fuels of a cheap grade, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended. V e

Other objects and advantages reside in the special construction and combination of the various elements forming the invention, ref erence being had to the accompanying drawings forming a part hereof, wherein Figure 1 is a perspective View of one type of burner in assembled position.

Figure 2 is a vertical transverse sectional View therethrough.

Figure 3 is a longitudinal sectional view. therethrough.

Figure 4: is a fragmentary bottom plan view illustrating the manner in which the air draft space is formed between the walls of the base and the oil pan. V

Figure 5 is a vertical transverse sectional view through a circular type of burner.

Figure 6 is a top plan view thereof.

Figure 7 is a horizontal sectional view through the base of the circular burner, and,

Figure 8 is a detail showing the attaching means between the base and the burner.

Referring now to the drawings I have disclosed my invention comprising a base indicated at 5 which may be of a rectangular construction as shown in Figures 1 to 1 inclusive, or which may be of an annular construction as illustrated in Figures 5 to 7 inclusive. An oil pan 6 is formed within parts in position. a

the base having its'bottom section spaced above the lower edge ofv the base'whereby to form" an air space beneath the pan, one

of the vertical walls 7 of the pan being spaced in parallel relation from one of the walls of the base 5 whereby to form a verti-v cal air passage communicating with the air space beneath the pan tending-to cause an air draft for moving upwardly between the wall 7 ofthe pan and the side of the base; A bridge 8 communicates between-the wall 7 and the side of the pan 5 to form a support for the pan. 1 Y

The pan (land air space betweenthe wall 7 thereof and'the base 5 opens upwardly and the upper edge of the base is adapted to support a burner 9 dispose'd'along one side thereof, the supporting edges of the base and the burner being arranged in overlapping relation as indicatedat 10 to form a tight fit therebetween and at each outer side of the base and the burner I provide earsll forming means for securely attaching the p "The front end of the burner 12 is suspendedabove the pan 6 and is disposed slightly below the upper edge of the' base. Between the rear edge of the burner and the front ed'ge'12thereof is formed an upwardly extending air pocket 13 communicating with the air space between the vertical Wall 7 of the pan and the wall of the base and arranged to direct the air draft passing therethrough downwardly into the part6.

The inner end of the burner 12 is provided with a. longitudinally extending oi'l feed passage 14 having a threaded opening at one end whereby. to attach an oil feed pipe and having a cleanout plug 15 formed in its opposite end. A plurality of orifices 16'extend through the wall of the burner from the feed passage 14:, nipples17 being formed about said orifices arranged on the upper surface of the inner end of the burner 12. Flanges 18 are arranged at each end of the inner edge 12 ofthe burner to-direct any overflow of oil from the burner into the pan and prevent thesame from dripping. i I

Shields 19 are also formed at each the burner 12 to prevent oil from dripping over the side edges thereof.

In the construction ofthe burner in a circular form, a slight modification of the several partsisfound necessary, in such inside of stance the vertical Walls of the oil pan 21 are spaced from the Wall of the base construction provides for an air space he neath the pan communicating With the air space between the walls et the base and the pan. The annular burner 28 in this construction i s" provided with an annular oil passage 24: connecting with an oil teed pipe 25, the upper "edge-oi. the burner being in dined inwardly toivardythecenter of the pair'as likewise is thecaseivith respect to the rectangular burner, the inclined sinfa-ce of the burner being provided withzoii tic-es 526' having nipples 27 formed thereabout and communicat-i 1 With the'oilpassage The lnner edge of Cl18 bL 11 11I BX tends inwvardly-over the oil pan 21 and has adownwardly extending flange 28 formed about its lower inner edge. The flange thus comprises a: drip for any excess of. oil discharged through the orifices and Which is not-consumed during the operation of the burnemthereby depositing the same intothe pan 21-." r "Thequantity of I fibre asbestos indicated at '29 may; be placed-1 Within the pans 6 and 21, which after beingsaturated Withthejoil may be ignited so as to heat the inner edge ofthe oil burner extending. over the pan thereby tendingto create a gas: from the oil Within the 'oilpassages which upon being discharged throughfthe orificestogether with-the overfiowfof oil therefrom Will becomefignited from the flame Within the pan. The air draft directed against" the inner edge of theburner by 'the burning of the oil Within the pan will intensify the-burning oi the gas and oil from thefburner.

ltl is obviousfthat"the invention is susceptible of various changes in shape, size and form, Without departing from the spirit munieat-ingwith the air space beneath, the

pan, a burner arranged upon the upper edge ot 'the base having one edge extending inwardlv over the pan, an oil passage termed in the burner extending throughout itsv rea, orificescommunicating therewith and a drip flange carried at the inner edge or the burner and suspended above said pan. I

2. In a device oi the'class described, a base, an oil pan arranged Within the same and supported above the loi'ver edge of the base with the \valls oit the pans spaced irom the alls the whereby toform an air passage opening upwardly xtronrthe base and the pan, a burner supported" upon th e upper edge of the base with its innenedge extendn ig over the pa n and vhaving an oil passage formed therein, orifices arranged in the. upper suiflfacje, ofathe burner coininunieating with said passage, said orifices having nipples formed thereabout and a, flange arranged on the lower inn'er edge of said bulfnfil'; I
