OIL BURNER.

Application led July 1, 1922, Serial No. 572,220. Renewed Hay 2, 1824.

T all whom 'it may concern.'

.Be it known that we, HERMAN J. ALLEN and MARVIN Lun. citizens of the United States, residing at ,lVichitzn in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Oil Burners. of which the following is a description. referring to the drawings which accompany this specification.

Our invention relates to that type of oil burners in which through the employment of a motor in operative combination therewith and .by elements rotated thereby, a centrifugal motion is accorded to the oil and air mixture and blown as an afomized spray upon the burner surfaces for ignition purposes to then develop a horizontal and annular flame. Our type of burner may be employed in'lieu Iof the coal grates generally employed in hot air, steam. hot water and vapor-vacuum furnaces; it is especi-ally designed however for use in domestic installations employing annular sections, vertically combined. Our burner and motor are combined as a unit in the manufacture of the composite device.

Previous installations of. the general character described above have proven objectionable in varied respects, for instance the proper adjustment and control of the air supply has not been properly taken care of; the waste oil is recollected for storage in our invention and all packings and stuifing boxes eliminated thereby rendering the device operable in a more perfect manner. Due to the inverted bell-shaped character of the centrifugally operable oil throwing receptacle. certain relations of a. fixed air' supply. oil reception and oil-air agitation are developed and whereby a primary co-v mingling is accomplished prior to meeting. the baffle plate and later permitted to follow the outwardly flaring lines of the inverted bell in the centrifugal travel of the oil-air mixture and toleave same as a spray to meet a further air spray likewisey cen- -trifugally functioning and adjustable features for controlling the volume of said secondary source of air supply.

Our burner very efficiently heats the furnace by directing the flame in an outwardly disposed annular flame in contra-distinction to burners of the central conical type or inwardly disposed horizontal type, a 5 major portion of Whose heat units are lost 'porting elements l0 is 'threaded hub 20 of the through the flue without being absorbed by the walls of the furnace or heater.

There are no heat losses on account of sooty deposits, our burner under operating conditions giving a smokeless flame, consequently labor costs of removing sooty deposits are entirely eliminated.

In the drawings, Fig. 1 shows a vertical section of' our improved burner as supported from adjustable leg elements and in combination with a vertically disposed motor shown in elevation: allied features essential to the operation of the burner mechanism are illustrated in section and in their -preferred arrangement in the combination. Fig. 2 is a top view of Fig. 1 with the bellshaped deflector and heat protecting-element removed. Figs. 3 and 4 represent sectional views taken along the lines 3*.3 and 4 4. Fig. 1 and looking respectively, in the direction of their arrows. Similar numerals of reference indicate correspond` ing parts throughout all the figures of the drawings.

Referring to the drawings; mounted upon a plurality of leg standards as supshown a horizontally disposed metallic plate 11 as a base or seat for the burner. The legs 10 are threaded at 12 upon which are screwed unions 13 and b v means of which the plate 11 is properly leveled and positioned at a desired level within the firebox lof the furnace. The periphery 14 of the plate 11 closely approximates the shape and area of the firebox and packing,v(not shown) may be employed around the edge 14 so as to prevent air currents from below rising upwardly towards the flame. A motor 15 supported on legs 16 resting in a central base supporting casting-17 is centrally and vertically disposed beneath the plate 11 with the motor shaft 18 'in a vertical plane as disclosed. IThe shaft 18 is threaded at its end 1-9 to receive the casting seen in Fig. 1 which includes radially extending fins 21 and upon which a horizontally disposed baffle plate 22 rests and is secured by the lock nut 23 engaging the threaded end 19 of the shaft 18. It will thus be seen that the parts 20, 21. 22 and 23 are adjustable from or towards the motor for purposes later explained. The plate with asbestos 24 or other suitable material. At 25- is shown an inverted be1l-shaped ele- 11 is covered ment which is bolted as at 26 to outer flange elements 27 of the fins 21. It. will here l be noted that the circumference of the baffle "plate 22 does not quite reach to meet the bell element 25 thus providing an annular passage 28 for oil and air fiow. as later explained. A plurality of radially extending fins or wings are formed as at 29 on the upper and outer surface of the bell element 25. A circular opening is centrallyv formed in the sheets 11 and 24 at 30 thus ycurled upwardly to form a trough element of annular character as shown at 31.

posited into said A casting 32 is bolted as at 33 to the top end of the motor 15 and isprovided with an annular ringportion 34 to receive unburnt oils as later explained and from which outwardly leads to a storage tank (not shown) a pipe 35 for carrying away the unburnt oils as collected in the annular ring portion 3 4. j An L shapedtubular element 36 is cast `integral with the member 32, the oil supplylpipe 37 engages the L element 36; a pipe 38 leads away from the L 36 and its upper end is bent towards the trough 31 so that incoming oil is first detrough 31 of the motor driven bell element 25. 1t will also be noted that. the fins 21 are likewise in rotation and air entering the opening in the base of the bell 25 mingles with the oil flow centrifugally traveling upwardly and outwardly past the passageway 28; it will here be noted ow the inverted fiaring edge portion of the bell 25 extendingbeyond the baffle plate 22 serves to s till support and control the oilair mixture prior to casting it youtwardly for burner consumption.

Concentric with and supported by the elements 11-24 i's shown the-circular disc or metallic plate 39, whose flanged periphery 39x seats upon the plate 1124 and its cen- .tral yportion being cut away to provide an ope ...equivalent to the opening 30, is A:form as an annular trough element 40 fromwhich leads a pipe 41 to carry unburnt oils that may be collected in the trough 40 into the trough 3 4 for'storage disposal. An asbestos covering 42 upon the plate-39 comletes" the burner installation, proper. It

ing however noted that the periphery' of the covering 42 is above the periphery of the inverted bel 25, while the lower or central portion of the dish-shaped plate 39 is arranged at a` lower level than the periphery ofl the bell 25.

Arranged above and concentric therewith is shown a bell shaped element comprising a horizontal base plate 43, a bell shaped element 44 supported by and bolted to the plate 43 as at 45 and having a central threaded hub portion engaging for adjustment purposes abolt 46 depending from an'upper portion of the rebox of the furnace (not shown). A second bell shaped element 47 covered by asbestos covering 48 caps the first mentioned element 44 to provide an air spacing 49. The plate 43 is faced-with asbestos 50. j

v The opening 30 may be restricted in size or otherwise closed or partially closed for major adjustment purposes; by means of the adjustments 20-23, the bell 25 may be raised or lowered in the opening 30 thus enlarging ordecreasing the air passage leading to the fan elements 29 which force this adjusted air current to mingle with the first mentioned air-oil current as centrifugally cast from the upper periphery of the bell 25 towards the periphery of the burner covering sorbed by the asbestos 42 flow back through 40-41--34 and pipe 35 to storage.

The bell elements 43-49 insulate the bell 28 and its oil-airspray so that the vaporization takes place in the outer annular ring where the ignition takes place. It will be especially'noted that the position of the baffle plate 22 serves to prevent oil striking the plate 43, while assisting in conducting the flow of. air-oil mixture upon the inner surface of. the bell 25 for centrifugal horizontal casting purposes.- j

The asbestos covering 42 is relatively hard 42. Such oils as are not burned or ab and compact and is covered around its periphery by4 an annular ring 51 of absorbing asbestos as a wick like element.

In addition to the adjustment-s 20-23 mentioned above' for controlling the size oftheopening 30, we may. employ the auxiliary and positively acting damper mechanism illustrated in Figs. 1 and 4, wherein the opening 30 is shownfully closed, the only passage being that through the opening 31x through the base of the inverted bell-shaped device 25. 'y

Referring to Figs. 1 and 4, the damper comprises two

sections

52 and 53, preferably of sheet metal, each pivoting on the bolt 54 attached to the plate 11v and against :which they are arranged to slidably be moved as later shown. These sect-

ions

52 and 53 are .shaped to fit around the bell device -25 and spective sections52 and 53 as illustrated so that when the bar 56 is inwardly moved, the

sections

52 and 53 will pivot outwardly to their ultimate o1' dotted positions 52* and 53". and in which position, the opening 30 will be fully and4 entirely uncovered to permit maximum air passage. j

It is thus apparent that any desired area may be given the opening 30 intermediate that of zero and maximum areas; while the adjustments at 2 0 and 23 operate to accomplish a similar purpose with the additional features of adjusting the angle of centrifugal spraying action to best function with the bell device .43 and asbestos ring 51 for burner pur oses. l
