UNITED STATES PATENT ORRIOR.

OF NEW ORLEANS,

OIL-BRNER.

To all whom it may concern: l

Be it known that we, EDGAR LOUIS STREAM and WILLIAM J GIBBENS, citizens of the United States,A residing at N ewOrlean's, in the parish of Orleans and State of Louisiana, have invented certain new anduseful Imrovements in Oil-Burners; and we do herey declare the following to be a full, clear, and eXact description of the invention; such as will enable others skilled in the art to which it appertains to make and use lthe same. I Our invention relates to im rovements in oil burners of that .type in W ich the oil is I5 atomized and is blown into the furnace by the @is vica of one or more jets of steam.

Our invention will be understood by reference to the accompanying drawing, which shows theV burner in central vertical` section with the steam pipes in elevation.

A represents a casting containing a mixing chamber and rovided with the curved enlarged rear en A andfthe tapered passage A2 and the bottom outlet casting is provided with screw threads a', cagando?.

B represents a curved pi e opening into said mixing chamber forwar of said enlarged portion A rovided with a flange bi-held beneath the shoulder a of the casting and provided with the and the curved outlet b2( v C represents a sleeve-banged as at c and held by the shoulder d of the cap D whichv is yscrewed over, the screw thread c3. -This sleeve C is screw-'threaded asjat c to engage the screw threads. e of theoil pipe E. Between this ipe and the sleeve C is an annular chamber C@ above which is a flange E0 secured to the -pipe E and slotted as at e0. upper end of the pipe E terminates inthe conical inlet b nozzle ez; which is spaced. from the coned inlet b ofthe curved pipe B, thus leaving a tapered annular passage between the two.

thus closes the rear Y or lar e end-of the casting'A. This plug H is preferably provided with a curved taperedend H', and with a chamber H0 connected to the branch pi e' F2,and connected with the mixing chaml er by the erforations h". K represents a cap general y similar to the cap D, to` which any suitable nozzle or twyer may be connected. A

i he operation ofthe device is as follows Suppose it is only'desired to feed a limited supply of oil to the furnace, the pipe E being connected to the source of'oilsuppl in the usual well known way, and controlle by any suitable valve, not shown, oil is forced by e2, and steam is admitted through the pipe'F. This steam will rush through the o enings e0, forcing up the oil through the nozzle e2, and the mixture vwill pass through the outlet?)2 and strikingthe curved tapered plug H', the oil will be thorou hly atomized an will be 'blown backward t rough the outlet -A2 to therfurnace. n'this operation the branch pipe F'and the chamber H and perforations fr have no if it 1s desired to still'further increase the supply of atomized oil fed to the nace, open :wider the feed valve (not shown) in the 'supply pipe E, turn on steam also through the pipe F2. `This second supply of steam will entergthe chamber H0, and rushing forward through the perforationsvh", will cause a larger supply of Oil to be atomized and therefore more oil. canbewsuppliedv .through the pipe E, andl thiswill become ,thoroughly atomized by the currents of steam meetin each other at varying angles, and the entire -mass will be blown through the assage A2 to the furnace. e do'notmean to coniine. the invention go to the precise details of construction or to the e s team pipe which is ro-l which plug engages precise combinations and arrangements oiparts', as these vmay be varied in many re- 'spects without *departing from the spirit of ourfinvention. v n p l Having thus described our invention what we claim and desire' to secure byfLetters'Patent of the United States is 1.
