ATMATICALLY-OPERATED OIL BURNER.

Applicationk med' April 4,

improvedoil burner, and Fig. 2 kis a top Y plan thereof.

Our invention is not restricted to the pre oise construction and arrangement of parts herein shown and described, nor to the va# rious details thereof, as the same may be modified or rearranged in various particulars without departing from the spirit and scope of our invention, one practical 4embodiment of which has been herein'illustrated and described withoutattempting to show all of the various forms and modiiications in which our invention might be embodied.

Our device comprises an upwardly coned hollow inclosure 1 having several outwardly directed horizontalbottom lugs 2 secured by bolts 3 and nuts 5 to registering end lugs 4 of a basal member 6 which has openings 7. The upper end of vthe inclosure `1 is open. The basal member 6 is shaped with a circular central portion 8 with raised rim as an oil drip cup around and integral withA an axial and fixed hollow cylindrical oil delivery conduit 10-11 whose upper portion above the cup 8 traverses the hollow'of l,

the inclosure 1 centrally to project terminally thereabove and has a spreader dis` coidal or annular plate 17 lixed upon its upper end over a constricting annulus 16 fixed in the upper part of thevbore of the conduit, which thus limits the delivery of oil upwardly over and upon said plate 17. The lower end of the conduit 10 which depends below said inclosure 1 is closed by a plug 13 sealed therein which has an upwardly opening conical step bearing hollow 14 to step therein antifrictionally the conical lower end of a rotary axial shaft 18 een trally in the hollow 12 of the conduit and to project above said spreader plate 17 Vto carry fixedly a somewhat wider circularv plate Von its upper end atl 21.

The numeral 24 denotes a disk positioned below the spreader plate 17 and just above 192e.V serial 1101.262280.

the openv top.l of the inclosure 1 and whose marginal part is cut and shaped with ay number of circumferentially.y arranged inclined vanes :26. The inner' raised rimof the disk Vat V25 surrounds the upper vand diminished termination of the conduitipart 11 in spacedfrelation and horizontally. Bolts V22 and nuts 23 secure iixedly vthe disk 24,'to

and depending from the top fplate 21 outside of and below the spreader plate 17 .y

The lower conduit part 10 has a threadedy aperture to seat a threaded end of an oil supply pipe 15 which should leadto'a tank of fuel oil under head. The drip cup 8 has 1n itsbottoni a threaded hole in which is secured the threadedvend of a conduit 9 to drain oil from the cup to a suitable receptacle not shown.

The inclosure 1 may be mounted iny thev When it is desired to operate the burner, ik

oil is supplied the conduit 10-11 under head which oil issues at the top flowing equally outwardly radially over the circular spreader plate 17 and droppingin drops upon the disk 24 inside the vanes 26 but which, when the disk and vanesare rapidly rotating is thrown out-upon and from the vanes horizontally around the upper edge of the inclosure 1, being atomizedthere in v a misty condition and mingled with air constantly drawn by suction throughlthe coni; cal inclosurev 1 anc then through the interstices of the vanes. The disk 24 andyits vanes 26 are initially thrown into rotation manually while a piece of blazing paper or other material is held-near the vanos which pick up and atomize and deliver the o1l into the Zone 1n which the igniting material is positioned, igniting the oil, and which causes a wide annular zone of Vflame-around,

the vanes which are 4kept automatically in inclosure 1.r This air draft keeps the conduit 10-11 cool, necessary in'this class of oil burners. Any overflow of oil from'the disk 24 passesinto the cup `8 and drains away by the pipe 9. Oil delivery and relaas specified by valve pipe 15.

. tive speed of the vanes are valve controlled,

Having described our invention, what wc claim' as new, and desire to secure by Letters Patent, is z An oil burner, comprising in combination, an openend inclosure, a conduit in ,communication with a supply of fuel oil under head and traversing said inclosure centrally to have its upper delivery .end project thereabove the lower end of the conduit beinclosed by a step-bearing, said conduit having a concentric encircling oil drip-cup Within the lower part of said inclosure, said drip cup having drainage means, an annular spreader plate mounted concentrically around the upper end of the conduit toreceive oil therefrom, a shaft mounted axially Within said conduit and stepped in said step-bearing and projecting above the con duit and inclosure, said shaft being spaced from the inner wall of the conduit, a disk secured coaxially upon the upper termination of said shaft, anA annular plate positioned below the spreader plate coaxially and rotatably and above the top of said inclosure, saidy annular plate having peripheral vanee, and connecting means between said disk and said annular plate, said tures.
