To all whom t may concerti.'

Be it known that l, FRANK JoHNsoN, a

`citizen of the United Statesand a resident ot Oakley, i county o1 `@entra Costa,fand State of California, have invented a new and useful @il Burner, of `which the` following a specification.- l

My invention relates in'` general to burners tor cooking and heating purposes and has reference more particularly to a burner especially adapted 'for use inburning oil and the obgect oi.I the saine is to produce acheap, v

simplel and efficient in'eans fior utilizing a cheap grade'of liquid` fuel, suchas kerosene, for heating and cooking purposes, K

A further object of my invention isto construct the burner in such a inanner that the highest degree ot heat possible .will be obtained tromthe liquid fuel, and .to off-set the danger-oi using the saine due to exploM y sion orother `causes usually presentin uti lizing combustible liquidsas a li'uel.`

My invention is illustrated .inthe accompanying' drawings in which ldigurey 1 isa View in side elevation andpartly in section oit the yburner and the `parts which are usedl in combination therewith; Figure 2 is a plan View oil? the burner; 'Figure i; atransverse vertical section .through the i middle yoi' the biiirner and Figure el `isal bottom plan view.

Referring now to the drawing indetail, lf wish itA to be` clearly `understood that iiy burner may be used in'various ways, tor ini 'stance it may beanstalled in the hre bon ot' a wood or coal cooking range, the hre box4 of a. furnace-1l or otherl heating stoves, or

otherwise set up for use according to rc" quirenients. ln some instances, of course, certain changes would be required to accommodate the burner to various uses, for in stance, sometimes only ay single burner, per se, would be required instead of two burners as illustrated in the drawing. The. ,again, more than two burners may be required and the general. shape or design oil" the burner might have to be changed. In all cases, however, the saine simple and convenient, practicable principle is employed.

Considering the illustrative embodiment in this light the showing made in the draw ing comprises a pan or the like (1) preterably supported by Jfeet or legs (2),( The pan comprises a cast metal structure with the feet or legs (2) made as an integral part thereof and with a relatively deep trough vextending continuously around the outer yedge of the pan, with exception of the danis (et) and (l) arranged in the trough on opposite sides thereoiE to provide a supportfor the pre-heating or e vaporizing tube which is supported over the trough with the end. vthereotl threaded into a i1'*(7) having a downwardly presented connection extending through an opening in the dani and made to receive the nipple or the like (8), the threadedend (9,) of which is` adapted to befconnected to the kfuel supplyy pipe which leads from a liquid reservoir not shown. i f

The ends of the pre-heatingor vaporicing tube (5) may be considered as an intalee and the end (10) as an outlet, the saine having a threaded engagement with a litting (l1) which. connects with! the inaniifold pipe (12) cast as an integralipart ot the ilat inanitold or distributing plate ,(13) which is ot substantially the saine size as the` `area of the pan surrounded by they trough rilhe manifold pipe is` arranged in upstanding relationto the plate 4(13) and has a eap(1l) to close the saine with an opening (15) in the cap Vtoiadmit air. `Screwed or otherwise lined between the fit-4 ting (11) and the upstanding `manifold pipe (12v) is a nozzle (16), the same having a ysrnall axial bore. (17) establishing geoni inunication between the tube and the nl side of the' manifold pipe `(12) through the l iitting (11).` Produced in the pan (1) concentric wit i the insideot` the manifold pipe (12) is `an airiopening or intake The. kerosene or other liquid fuel, as the case'inay be, is supplied by air pressure to the preheating or vaporizing tube (5) as previously mentioned and to start the burner, alcohol or other combustible liquid is poured into the trough (3) to heat the tube (5) and the lrerosene distributed therein to vaporize 'the saine so that it is forced through the nozzle (16) into the 'inanitold pipe (12) in a spray and the air entering in the opening (18) nia-king a combustible which' circulates through the opening (19) in the vertical upstanding part (20) of the casting and back of the inanit'old pipe (12) where it 105 enters the relatively deep distributing well (21) from where it circulates throughout the space under the plate (1S) to the openings (22) and (23) which communicate with the slanting internal openings (24) of the 110 burners, per se. The burners are bolted through their flangestothe top "of the'plate as best shown Iin Figure l, andfeach Athe plate- (13) so as to permit a certain amount of the carbureted charge toeseape,

y andthe' same' maybeburned at this-,pointto npipe; y

keep '.the preheating or vaporizing. tube (5) hot,` at all times.

From the above it will be readily seenthat I have produced apractical device which is extremely simpleto make, convenient `to use and-requiringlonly ordinary-skill to operate audit might also=be addedthatfitwill use a minimum amount of kerosene or other-liquid fuel, 4consemiently."it-is cheap to use.
