OIL-GAS BURNER.

maaeaa Application filed January 19,1914. Seriai No. 813,006.

To all whom it may concern Be it known that I, WALTER R. THATCHER, a citizen of the United-States, residing at Oskaloosa, in the county of Mahaska and State of Iowa, have invented a new and useful Oil-Gas Burner, of which the following is a specification. V

The invention relates to improvements "in oil burners.

The object of the present invention is to improve the construction of oil burners, and

to provide a simple, practical and inexpensive oil burner of strong and durable construction designed for use in stoves, furnaces and other heaters, and adapted to enable crude oil, refined oil, or alcohol and the like to be employed as fuel, and capable of converting the same-into a gas and of entirely consuming the latter.

A further object of the invention is to provide a stove of this character in which the degree of heat may be readily controlled bv the flow of the fuel-to the burner and in which the fuel will be caused to s read over the burner in a thin sheet, where y the entire fuel delivered to the burner will be converted into a gas and all danger of clogging the burner thereby eliminated.

With these and other objects in view, the invention consists in the construction and novelcombination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. v

In the drawing: Figure 1 is a central vertical sectional view of an oil gas burner,

constructed in accordance with this invention. Fi 2 is a plan view of the upper burner pita. Fig. 3 is a similar view of the lower tray. 7

Like numerals of reference designate corresponding parts in all the figures of the drawlng.

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, the burner comprises in its construction a top burner plate 1, and a lower tray 2 designed to be constructed of cast iron or other suitable material-and adjustably mounted on a vertical branch or portion 3 of a supply pipe 4, which extends to a suitable source of liquid fuel supply, the flow of the latterto the burner being controlled by a needle valve 5 of the ordinary construction. The fuel suppl pipe preferably consists of an inch pipe, lint the iameter of the pipe and the size and shape of the burner ate and the tray may, of course, be varied to suit the character of the stove, furnace or other heater to which the burner may be applied.

Specification of Letters Patent. I Paiggmtggd Dem- 29 flgfllgt The upper portion of the vertical branch 3 of the supply pipe is provided with exterior screw threads 6,'and the burner plate 1, which is preferably in the form "of a hori-v zontally disposed disk,is rovided with a central threaded opening andis screwed on the upper end of the vertical branch3. The burner plate, which is imperforate from the lower edgeof the burner plate,

The burner plate has a cm the central opening to an outer and thelotvenQpe of the latter is provided with a recess having an outer downwardly and outwardTy mclined peripheral wall 12 to enable the burner plate to constitute a hood and adapted to hold the heat and flame in starting the burner, and caable also of deflecting the air downwardly 1n the direction of the lower tray 2 in the operation of the burner. The oil or other liquid fuel is adapted to spread out in a thin sheet over the upper face of the burner plate as it flows from the supply pipe 3,

and after the burner plate becomes heated such fuel will be immediately converted into gaseous form and burn. The recess 8 is desi ed to retain such fuel on'the up er face 0 the burner plate until converted into a ioo gas, but if it is desired to increase the heat is disposed horizontally,is of greater diam-- .eter than the burner plate and consists of a central hub portion or ring 13, radial arms 14 and an outer rim orannular body portion 15, provided in its upper facewith an annular recess or gutter 16 increasing m depth outwardly and forming an outer upwardly extending wall 17 The annular groove or gutter is located beneath the lowerperipheral edge of the burner plate and it is of.

sufficient width to receive the liquid fuel flowing from the burner plate. The bot-' tom face of the annular recess or gutter is inclined and extends downwardly from the inner edge or face'of the rim 15 to the wall 17. 'The recessor gutter .16 is adapted to catch the liquid fuel flowing over the burner plate and it also serves as a starting receptacle' in which oil may be burned to heat the burner plate in starting the burner. The hub or ring 13 is provided with a threaded opening 18 and screws on the threaded portion .of the vertical branch of the supply pipe being spaced from the top burner plate.

he rim 15 of the tray 2 is provided in its lower face with an annular groove '19 re- I ceiving the upper edge of a cylindrical air shaft 20, constructed of iron or other suitable material and consisting of a vertically disposed cylinder having imperforate walls and arranged upon and extending upwardly from the grate 21 of the stove 'or other heater to which the burner is applied. The

vertical branch of the fuel supply pipe extends upwardly through the grate, as shown in Fig. 1 'of the drawing, and the openings between the grate bars are sealed beyond the air shaft by fire clay, asbestos, or other noncombustible material as well as at the other openings in the fire box of the stove or heater, so that the air for supporting combustion must pass upwardly through the air shaft to the burner. The air ascending the cylindrical shaft or flue 20 passes through the openings or spaces between the arms 14 of the lower tray 2, and passes outwardly over the lower tray through the space be tween the same and the upper burner plate and is adapted to support combustion when fuel is burned in the oove or gutter in starting the burner and also after the top burner plate has become heat-ed sufliciently to generate gas from the liquid fuel. When the fuel is burned in the groove or gutter to start the burner, the lower hood portion ofthe burner plate is adapted to hold the heat and flame so as to cause a rapid heating of the said late and a quick starting of the burner. rude oil, refined oil, alcohol or similar liquid fuel may be used in the burner, which is adapted to produce an intense economical heat. In operating the burner, the fuel may be controlled so that after the starting of the burner, the burner plate will convert into a gas the entire amount of fuel fed to it. If the top disk or burner plate does not furnish sufiicient heat, the flow of fuel is increased to cause a portion of the same to be delivered to the the same manner as the upper plate. By in creasing the number of lower trays, a.

be obtained.
