OIL BURNER Fil ed Sept. 15, 1950 a INVEIYTOR.

Patented 'June 13, 1933 UNITED STATES ,PATENT OFFICE H WILLIAM R. WINSELL, OF KANSASCITY, MISSOURI on; BURNER Application filed September 15, 1980. Serial No. 481,835.

burner embodying my invention, an oil inlet pipe being shown fragmentarily.

Fig. 2 is an enlar ed longitudinal sectionthrough the burner, illustrating the efie'ct on fuel of the novel construction.

Fig. 3 is a section on the line 33, Fig. 2. Referring in detail to the drawing: 1 designates a casing or hollow body pref erably cylindrical in cross section and curved longitudinally to provide an open air inlet end 2 having an axis adapted to extend horizontally, and a slightly upturned open outa let end 3. The casing curves downwardly from the inlet end and then upwardly tov form the outlet, thus providing depressed upper and lower Wall portions at points des' ignated 4 and 5 substantiallymidway of the casing.

Feet

6 and 7 comprising transverse wall-like bosses are formed on the casing for supporting the same in a predetermined positlon'for a purpose presently disclosed. I The casing is provided with a side inlet 8 adjacent the top portion thereof, and spaced substantially from the edge of the open end 2, and a transverse plate or trough 9 having ends sealingly fixed to the sides of the casing to form a channel or chamber 10 is curved to form a trough-like shallow recess portion 11 to receive Oll from the inlet. The front end edge portion 12 of the plate is flat, and extends toward the air inlet in a plane substantially tangential to the oil inlet, thus forming one edge of a mouth through which air may pass fromthe casing inlet through the chamber 10. v

The front edge 13 of the trough is slightly lower than the portion 12, to cause oil to tion thereo flow for war dl from the trough, andsaid edge is curve into oval form, whereby oil. moving from the trough will flow over the surface of said edge to the curved lower face of the trough, and drip from the lowest p01- asindicated at 14. Located below the trough and inclined downwardly and forwardly is a plate 16 having ends sealingly attached to the casing,

and extending a substantial distance foran wardly from the trough. Therear edge of the plate 16 is located sufliciently rearward ofthe point l ltoassure reception-of dripping-oil by the plate, and the'front edge extends substantially to the 'space in the case5 ing defined by the depressed upper wall portion 4. i

The delivery edge 17 of the plate 16 is formed oval to conduct oil to the lower marginofsaid edge for dripping, therefrom.

A second transverse plate 18 inclined longitudinally of the casingvoppositely tothe inclination of the plate 16 has a front edge a located slightly ahead of the front edge of the plate 16 and slightly below the extended plane of the lower face of said plate, to receive oil dripping from the plate 16 and conduct the oil rearwardly in the casing. The rear edge of the plate 18 has the oval formation. '80

A final member 19 of the series of inclined plates is inclined oppositely to the vertical ly adjacent plate 18, and has a front edge located substantially adjacent the point 5 representing the lowest place in the bottom wall portion of the casing. I

Farmed in the rear edge portion of. the plate 19 and spaced rearwardly from the rear edge of the plate 18, is a transverse recess 20 forming a trough or well. into which oil flowing fromthe plate 18 may pass, and a wick 21 consisting of asbestos f or. like absorbent material, preferably resistant to heat, is mounted in the recess to receive and hold oil and provide convenient means for initially igniting the fuelr Air has access to-the casingthrough the air inlet end 2 for supporting combustion of the oil,and air will pass freely through j the several-passages 'defined'by the trough a and plates.

In order to control the airjsupply, I provide a damper including triangular leaves or

vanes

23, 24 and 25 having inner ends mounted on a bolt 26 supported on the arisof the air inlet by an ear 27 extending fronr the casing. A spring 28 mounted onthe bolt bears againstthe nut 29 thereon to urge the bolt head 30 into engagement with the leaves, whereby ally latched to the ear 27 and may be moved rotatively to any desired positions to form and adjust the sizes and POSltlOllS of airadmitting apertures in the ,air 1n1et end of the casing.

The outer ends of the vanes ,bear against and slide over a shoulder 32 formed in the' inlet end of the casing.

A valved "oil supply pipe 33 may be threaded inthe oil inlet of the casing for delivering fuel to the burner.

In using the-device, the

legs

6 and 7 support the casing in such a position as to maintain the trough and plates horlzontal and prevent lateral tipping of the caslng, thus enabling the I livery edges of the trough and plates.

Oil delivered through the oil inlet Wlll collect in the recess of the trough, and flow therefrom to drip from the lower face thereof to the plate 16. P a r Attention is called to the communlcating relation between the trough chamber 10 and air inlet, whereby air is constantly supplled to the oil in the trough, and formatlonof carbon therein is thus avoided.

' The oil will flow forwardly over the plate 16, and drip thence to the plate 18, to flow rearwardly in the casing and pass vto the plate 19.

Upon initially setting up flow of fuel, oil passlng to the plate l9will tend to splash to the wick,'and provide a body of oil that may be ignited to suitably heat the plates and set up vaporization of the fuel.

A fine mistor thick vapor will rise from each of the plates while the oil is flowing, which will be driven'by the draft created by air moving from'the air inlet through the several compartments into the flame formed 1 at the front edges of the plates by the burnvapors. j 7 7 he tubular casing curved as shown and provided with longitudinally inclined plates forming passages. at the inlet end thereof, thus provides a combustion chamber portion adjacent the upturned outlet;

The damper vanes may be adjusted to provide a desired opening or group of openings for controlling inlet of air to" the several passages, and areadapted to. admit air to the upperpassage or trough chamber 10 when any combustion supporting air is passin in-. to the casing, due to the spacing of the ront the vanes are frictionoil to flow evenly over the deedge projectin edges of the plates from the air inlet end of the casing.

What I claim and desire to secure by Letters Patent is:

' 1. An oil burner including a casing having open inlet and discharge ends, an adjustable damper at said inlet end, an oil inlet in the casing, an upper arcuate transverse plate in said casing forming a trough in 'receivingrelation wlth the oil inlet and having a rounded delivery edge tapering gradually into the lower surface of said arcuate plate to effect discharge of oil from the lowermost portion of the plate, a second forwardly declined plate for receiving oil dripping from the upper plate and having a third forwardly inclined plate projecting into the casing beyond the front edge of the secondplate for receiving oil therefrom, and a lower forwardly declined plate extending into the casing beyond the front edge of the third plateand receiving oil dripping from the rear edge of the third plate, eac of said plates having unobstructedcommunication with said discharge end. 7 Q 2. .An oil burner including a casing having open inlet and discharge ends, an oil inlet in the casing, an upper arcuate transverse plate in said casing-formin a trough in receiving relation with the 011 inlet, a second forwardly declined plate for receiving oil drlpping from the upper plate and located in the casing forwardly of the upper plate, a

third forwardly inclined plate located in the casing below and-forwardly of the second plate for receiving oil therefrom, a lower forwardly declined plate located in the casing below and forwardly of the third plate and having a rdcess and a wick in the recess in substantially receiving relation with the rear edge of the third plate, and'an adjustable damper at said inlet end of the eas- 1ng.

,3 An oil burner including a casing hav ing open inlet and discharge ends, an oil inlet in the casing, an upper plate havinga transverse depression-intermediate its front and rear edges to form a trough in receiving relation with said oil inlet'and having a rounded front edge at a lower level than the rear .edgeand tapering gradually into the lower surface of said depression to effect discharge of oil from the lowermost portion of the plate, anda second forwardly inclined plate for receiving oil dripping from the upper plate and having a front into the casing beyond the front edge of t e upper late. 4

.In testimony whereof afiix mv si nature.
