Application led, August 28, 1927. Serial No. 214,899.
My invention relates to oil burners and particularly to oil burners of a type which are adapted for-use in relatively small furl naces, such, for instance, as in the heating of private residences. It is, adapted Ifor use in large sizes.
The object of my invention is to provide a burner of a type of construction and operation which will be simple, easily taken care of and operated and one possessing certain features of automatic adjustment as between the oil and air supply and a burner which is easily installed.
Other objects of my invention will appear from study of the following specification.
This invention consists of a burner em-y ploying arotative or centrifugal oil distributor and one which has van air supply nozzle surrounding said distributor, together with a fan wheel located in the air supply leading to the nozzle and rotated burner taken through the plane which includes the oil controlling valve. Figure 2 is a central longitudinal section.
The burner employs a casing orrshe'll, onev which at its inner end has a tapering conical shape as shown at 10. Within this shell and axially positioned withrelation thereto, is a core 2 whiclr is axially bored to accommodate the shaft 30 of the rotative oil distributor 3. This 'core 2 is connected with thev out-er shell by arms 20, of which one is bored to provide an oil supply passage 21. This radially extending portion of the oil supply passage communicates with a port 22, which extends lengthwise of the core at theupper side thereof. The discharge end of this/port or passage 22, is atl the innerend of the burner c re.
The inner en of the core is provided with a conical bore 23 in which is placed the conical head of the oil distributor A3. This head 3 is secured to one end of a shaft 30, the other end of said shaft projecting into a cylindrical chamber 11` formed by the outer end of the casing 1 and a. cap or 'extension 4 secured thereto.
Secured tothe rear or outer end of the Y shaft 30 and in chamber 11, is a fan wheel y"5. The air forwcombustion is supposed to however,
be provided under suieient pressur VV.to cause a. rapidity of iow suicient to rtate the wheel 5 by its passage thereby and in doing so rotates the oil distributor 3.
Located in the outer section of the casing member 4, is an air controlling. valve 40,
this being of the type. ordinarily referred to as a butterii valve. This is secured upon a stem- 41, w ich extends without the casing and has an arm 42 extending laterally therefrom, forming a crank arm from which it is controlled. The air supply pipe 43 which is secured .to the outersection 4 of the casing communicates with a convenient source of supply of air .under pressure. This source may consist conveniently of a rotative fan or of a pump.
Ther body of the casing 1, has a bore extending transversely of the portion 21 of the oil supply channel and from one side to the other of l.the casing.I This bore 6 receives a rod which functions as an oil controlling valve. This rod has a port 61,extending transversely therethrough and positioned so as to register with the passage 21 of the oil supply. The rod 60 has an arm 62 extending laterally therefrom and forming a crank armby which it may-be rocked.
This arm 62 and the arm 42 of the air arm 62.
-` It is evident that if one of these arms is swung upon its axis the other is swung. These are connected so that as the air valve is moved to contract the passage and to thereby reduce the volume of air delivered', l
the oil valve is turned so as to smilarl contract or reduce the areal through whlc theoilis supplied. The intention 1s to have such a relation between-the two valves .that
reduction in the amount of oil supplied will cause a corresponding reduction in the combustion air supplied to the nozzle. These controlling arms 62 and 42 may beconnected with automatic control 'mechanisms or be adjusted by hand as may be desired.-
' In conjunction Awith the 'burner nozzle heretofore described, I provide a plate 7 which is intended to be secured to the .front wall of the furnace. This has a conical, inwardly projecting sleeve 70, of such size as to receive the conical portion of the nozzle and to provide an annular air inlet channel 71, through which additional air for combustion is provided. The casing of the nozzle and the plate 7 are provided with complemental lugs or arms at 72 and 73, which may be secured together by bolt 74, thereby making it possibleto quickly and easily remove the nozzle for examination or adjustment. The oil supply to the nozzle is provided through a pipe 24.
In the operation of this device the oil is fed-through the channels 21, 22 and discharged to the inner end of the core 2. As discharged it is received upon the surface of the conical oil distributor 3, which is revolving. This throws the oil outwardly into the annular blast of air under pressure which is being discharged through the annular opening between the cone 10 .and the core 2. It is thereby blown out and atomized sufficiently to secure eihcient ignition. As an additional means of securing combustion, air under ordinary draft is permitted to ow through the annular channel 71, surrounding the\\conical pipe 10 of the nozzle. In consequence aK thorough combustion of the oil occurs.
I have provided means whereby the effective area of the port 61 of the oil control valve may be adjusted. This is done by adjustin the rod 60, in whichl this portv is forme lengthwise in its receiving bore. To secure this the outer end of the rod is threaded and receives an adjusting nut 69.
,Also a threaded plug 66 is screwed into a bore in the casing and contacts with the inner end of the valve rod 60, thereby limiting its inward position. This may be adjusted as desired so as to employ a portion of the length of the port 61 desired. A lock nut 67 upon the plug 66 secures it firmly in adjusted position. At the opposite side of the casing a packing sleeve 68 is employed to prevent leakage of oil.
The bore receiving adjusting plug 66 is extended sufficiently to accommodate a spring 66 which bears against nut 69 t0 hold theI rod 60 always in close Contact with the adjusting nut 66.
What I claim as my invention is:
1. An oil burner nozzle comprising a central core and a surrounding shell forming an annular air supply channel, said core having radial arms connecting it with the outer shell, one of said arms and the core having passages for conveying oil to the inner end of the nozzle, said core having an axial shaft-receiving bore which at its inner end is enlarged to include the discharge end of the oil supply channel, a shaft journaled in said core and a conical distributor head carried by said shaft, within the enlarged inner end of said 'core and with its large end extending beyond the core end.
2. An oil burner nozzle comprising a central core and a surrounding shell spaced radially outward therefrom to form an annular air channel, said core being centrally bored to accommodate a distributor shaft,
said bore at the inner end of the nozzle being enlarged, the upper wall of said core being provided with anoil discharge channel discharging into the enlargement of said bore, a shaft journaled axially of said core, a conical distributor head fixed to the inner end of said shaft with its large end projecting from the bore of the core, and a fan fixed to the opposite end of the shaft with its vanos extending across the receiving end of the annular air supply channel.
Signed at Seattle, Washington, this 18th day of August, 1927.
