- UNITED STATES PATENT oEEioE- OLIVER B. DAWSON, OF EL PASOTEXAS.

CRUDE-OIL BURNER.

To all whom t may concern: Be it known that I, OLIVER B. Dawson, of

. El Paso, in the county of El Paso and State be'a full, clear, and exact description of the invention, such. as will enable others skilled in th'e art to nvhicli it appertains to make and use the same.

l vThe primary object ofithis invention is to rovide simple and highly efficient meansI for 'insuring the burning of the vapor oil gastof criide petroleiim' mixed with heated airmurrents, whereby,"V within the fire box of a stove or range, complete combustion will be obtaineidl with thtotal absence of smoke.

And a further object of my invention is to provide an attachment which may be readily .applied to use.

stoves and ranges now in general Briefly stated, I obtain -the desired results vaporizing the before it reaches the bottom Aof point it 'S point. of coinbustion, with columns of hot air, whereby an instantaneous and high temperature will be obtained.

The,y invention will be hereinafter fully Set forth and particularly pointed out in the In the accompanying drawings, Figure 1. is a vertical sectional view of a stove equipped with my present invention. Fig.

'2 is a transverse sectional view on line movably supported by a sight' feed chamber sight feed' chamber 2, which ,f'may construction,

be ot any preferred form` of but which is `preferably pro'- vided at/ its ,upper end with a tubular portion 2a.l Ito receive the lower end of a pipe 3 from the reservoir, .said pipe its exterior a flange or collar 4 ,ms a stopfor holding the reserxdiately above the sight feed chamber from' which it may be readily removed. WithirnI pipe 3 is a pet cock 5 for controlling the f low of the oil. From the bottom of the depends a tube 6 which extends down into the st0\ econventionally shown at 7, to a point near the bottoni thereof.- I preferably` form this tube with a the gas'producer, at whichiiared out and is united, at the Specification of Letters Patent. Patented May 28,1912. Application filed December 15, 1910.. Serial No. 597,530.

flared flange 6- at its lower end. According to my invention, the heat produced within the combustion chamber of the stove is intended to heat tube 6 to such a degree as to volatilize the oil before it reaches the lower end of the`tube. In order to insure contact of the oil with the heated wall of tube 6 I preferably locate in the lat-ter, Aat a point near the top of the stove, an inclined deflector 9 in the form of a. plate riveted or otherwise attached tothe interior of tube t5 and extending transversely across part thereof, but not closing the latter.

Immediately beneath' the lower flared end of the Vvaporizing tube 6 I 'provide a series of air inlet tubes 10 which are preferably ci'rcularly arranged on a support 12, which lat-ter extends entirely across thecombustion chamber, prevent-ing any air from passing from the lower to the upper portion of the latter excepting through the air tubes l0. The latter are preferably1 deflected .at their upper ends, at an' angle of about 45, as shown at 13, so as to direct the flame upwardly and outwardly into the space surrounding the vaporizing tube, thus securin a uniform distribution of the heat throughout the fire-box or combustion` chamber. These air inlet tubes project above their supportsuoli a distance' that they will be thoroughly heated by the burning gas or vapor, with the result that within a very short time after the vapor is lighted t-he airV passing through tubes 10 will 4be thoroughly heated. I find that by heating the air before it mixes with the oil gas coinplete combustion may be obtained within the tire box. The flame is drawn upw. rdly iu the fire box by chimney suction. Inv starting, a small quantity of oil is placed on sup port 12, which is preferably of pan shape,

and surrounds the air inlet tubes 10 so that the heat generated by this initial supply Y'of oil will not only heat the lat-ter tubes,'but

will heat.tube 6 so as to'vaporize the oil flowing against the heated wall thereof.

For the purpose of supplying additional currents of heated air, and thus insuring complete combustion within the tire box. I surround the va-pori'zing tube 6 with a series plate set into thel top of the stove, such pipes 4of down draft hotair tubes' 15 which are 15 at their lower ends opening in close'l proximity to the discliargeend ofthe tube The heat within the tire box will thoroughly heat tubes l and fresh air passing downwardly through sueh tubes will be' heated while in transittherethrough..

Any suitable means may be employed, for instance, a perforated plate- 1T, for holding tubes l5 in fixed relation to tube 6.'

From what has been said it will be seen that no eold air is permitted to enter the tire box; and that the air, whether it be introduced solely through the lower series of pipes 1.0 or in addition thereto throilgh'the series of pipes 15, will be thoroughly heated by the time it reaches the dist-barge end ot the vaporiZing-tube' G. l In consequence, com- .y plete combustion will be etieeted.v and smoke.

after the stove has been Well started, will be entirely eliminated.

Lhave shown a drip pan 20 beneath lthe lower seriesof air tubes-for Collecting any oil or by-produets that may in any way be allowed to pass through such air tubes.

I claim as my invention l. The combination with a closed tire-box having a chimney outlet, and an oil reservoir, of a Vaporizing'tube leading from the reservoir and depending into the closed tirebox, oil entering said tube being designed to be vaporized in its descent therethrough. a series ot' hot air tubes eireularly arranged relatively to the' lower end of the vaporizing tubefsaid hot air tubes opening at their upper endsvtoward the upper end ot' the tire-box, and n an impert'orate support for said hot air tubes for preventing air `trom passing into the fire box other than through said hot air tubes.
