ALBERT EDWARD GRANT, or NEW YORK, N. Y., AssrGNoR, BY MESNE ASSIGNMENTS, TO GRANT OIL BURNER CORPORATION, or WILMINGTON, DELAWARE, A coRPoRA:
TION OF DELAWARE.
OIL BURNEB.
Application filed October 15, 1923. Serial No. 668,568.
To all whom it. may concem:
Be it known that ALBERT EDWARD GRANT, a subjeit of the King ot' Great Britain, re siding at 3305 Broadway, New York, N. Y., has invented new and useful Improvements in Oil Burners, ot' which the following is a specitication.
My inveution relates to oil burners The object of my invention is to provide a device of very simple construction thats adapted to spray or atomize oil in providing a fuel mixture for use in furnaces of various kinds. i
The novel features of my burner are set forth in the drawings and following specifications in which the Construction and operation of the burner is clearlydescribed and the novel features specified in the clains.
Figure l is a longitudinal sectional View of a burner embodying the Construction and inventiou.
Figure 2 is an end view, the air and oil passazes being indicated in dotted lines.
A, indicates the body portion of the burner which is provided with a central passage A 'for steam and two passages B and C for air and oil respectively, which are preferably located diametrically opposite each other and at equal distance from the steam passage A'.
The inlet to the air passage is controlled by a valve D and the inlet to the passage C is also controlled by a valve E'but is used only for the purpose of cutting off the oil supply to the burner and not to regulate the flow of oil thereto.
The body portion A is provided with a uniform thread F, formed in its outer cylindrical surface, and an adjustable cap G is fitted to engage therewith and is held in adjusted relation thereon by a lock-nut H. l`he steam outlet end of the body portion A` is formed with a conical projection I and the steam passage A' is recluced in diameter at its outlet J to provide a passage approximately of an inch in diameter for the size of burner illustrated which is drawn on a 'full size scale for one size of burne'r.
The air and oil passages are each about ot' an inch in diameter, and the burner outlet K is about of an inch in diameter.
A chamber L is found when the cap G is moved to open the oil and air passages B and C respectively, to serve as a mixing chamber for; the air and oiland the cap G also serves as a valve to control the flow of oil from the passage C to the chamber L, and to some degree to control the flow of air from the air passage B. p The cap is formed with a conical seat Mito contact with the conical projection I to form a valve by means of which both the air and oil flowing to the outlet K may be simultaneously controlled by causing the cap to move longitudinally on the body portion and contact with said projection without entirely closing the air and oil passages B and C. N indi cates a source of oil supply and O a pipe leading therefrom to the oil passage The operation ot' the device lis as tollows:
Assuning stean or air under pressure to be flowing through passage AQ with valves D and E wide open and cap Gpositioned relative to the body portion A as shown: The steam flowing through outlet J expands in passing through the combining tube and creates a rarefied atmosphere in chamber L which at once draws air from passage B and discharges it through outlet K but no oil will be lifted to the burner as the air s-lighter than the oil and Supplies enough to the chamber L to prevent oil from rising to the burner. It now, the air valve D is partly closed the steam cannot draw enough air to the chamber L to prevent a low pressure therein and immediately oil is drawn from the reservor N by suction and flowing into hamber L and thence to passage P is mixed with air `from passage B and sprayed by the steam into the atmosphere where the :tull mixture is ignited and burned.
It will be understood that the cap Gr serves as a throttling valve for both air and oil and by properly adjusting the cap valve and air valve D in conplementary relation, and also controlling the steam pressure and consequently the volume thereot flowing relative to the flow of oil, a very perfect operation of the burner can be attained.
Having thus described my inveution I clain as new:
1. An oil burner of the character described comprising a body portion having an unobstructed central steam passage extending entirely therethrough and an oil and an air passage located diametrically opposite to each other at an equal distance from said ste-am passage, means for controlling the flow of air through .said air passage and a cap adjustable on said body portion adapted to close communication betweensaid steam passage and said air and oil passages.
;2. .An oilburnereomprising a body portion having an -unobstructedcentral r passage extending therethroug'h and provided With an extension, a cap carried by said bodyportion having an outlet arranged in alignment With said central :passage and of greater area, said body portion having an air rand'an oil passage communicating With said -outlet 'and &means for restricting the flow oi' air through said'air passage; said body portion and cap forniing a chamberin open communication ith -said out let and a'lso forming a -valve to close said ontlet.
3. Anoilburner conprising a` -body portion having an-nnobstructed central passage extnding therethrongh an'd provided 'With an 'extension, a capcarriedby saidbody portion 'having -an -outlet arranged -in' alignment 'Witll said central passage and of greater area, said body portion and cap forming a -chamber '=in open communication with 'said o'utletand also -forning a valve to close said -outlet, neans for holding said cap in adjnsted position on said body ;por-
tionhaving an unobstructedcentral passage extendng therethrough and provided With an extension, a cap carried by said body portionhaving anoutlet arranged in alignment with said central passage and of greater area, said *body ;portion having =an air and an oil passage connuncating With said outlet and means for estricting :the fiowof-airthrough said .air passage; said body portionand cap forming a chamber :in open 'communication with said outlet .and also forminga valve to close said outlet., and means for holding said cap in adjusted position on said body portion, the area of said outlet being =approximately :equal to the -snnofareas of the outlets of the stean, air=and gas passages.
In testimony Whereof, ALBERT EDw-ARD GRA'NT has :signed his name to thisspecification 'this th day of :September 1923.
