ranged as to prevent oil from accumulating and forming a. carbon deposit adjacent its discharge end within which the burner tip is located.
A further object of the invention is to provide an oil burner from which oil may be discharged into a relatively small combustion chamber at suilciently high pressure to insure thorough atomizatiom and to provide means by which the flame is-controlled so that it has no cutting'action on the chamber wall towards which it is directed. y
Yet another object of the invention is to provide an oil burner wherein means are provided for diverting a predetermined amount of air from the outlet pipe and introducing it into the combustion space in such a manner as to aid combustion, keep the discharge end ofthe outlet pipe around the burner tip cool, and to prevent the formation of a partial vacuum around the mouth of the outlet pipe by which a roar would otherwise be caused.
With these and other objects and advantages in View which will become apparent 'as the specication proceeds, the invention is hereinafter more fully described with the aid of the accompanying drawings, in which:
Figure 1 illustrates a plan view of my burner.
Figure 2 is a section on Athe line `22 of Figure 1.
Figure 3 is a front elevation of the casing, and
Figure 4 is a section on the line 4 4 of Figure 2. y y
AReferring to the drawings, 1 designates a base on which a conventional. motor 2 is mounted. Driven by the latter are a fan 3 and a pump 4. Suction and discharge pipes 5 and 6 respectively Y are connected to the pump 4.
Suitably secured to the discharge aperture 7 of the fan 3 is a tube 8 the opposite'extremity of which is mounted in an apertured flange 9 formed integral with the rear wall 10 oi a box-like casing 11. Concentrically supported in the outer extremity of the tube 8 is a smaller air outlet pipe 12; any form of supporting means may be employed for this purpose, in the present instance. rivets 13 extend through thel tube`8 and pipe 12 and between the latter and around the said rivets spacing sleeves 14 are arranged. The front extremity of the outlet pipe 12 is supported in 1932, serial No. 631,185
an opening 15 formed through the front wall 16 ofthe casing 11 substantially centrally of v its width and height, and terminate substantially ilush with the outer face of the said wall 16.
Secured to the rear wall ofthe casing of the fan 3 which is apertured is a fitting 1 7- having' an opening therethrough in which the oil discharge' pipe 6 terminates. Mounted in thetting l 17 in alignment with the adjacent extremity of the discharge pipe 6 is an oil feed pipe 18 which extends through the casing of the fan 3, and substantlally centrally through the tube 8 and outlet 'pipe 12. Moreover in the preferred construction the feed pipe 18 extends centrally beneath the fan rotor 3a at right angles to its axis so that no bends or curves are formed in the said feed pipe in order to locate its front extremity centrally in the air stream delivered through the tube 8 and pipe 12. On the outer extremity of the feed pipe 18 a burner tip 19 is provided.
Towards its front extremity the oil feed pipe 18 is supported by a spider 20 having a plurality of K blades 21 thereon the outer margins of which rest against the bore of the outlet pipe 12. By these blades 21, which are stationary, a swirling movement is imparted to the air passing through the said pipe 12.
Some air passes through the annular space 22 provided between. the tube 8' and the outlet pipe 12 into the casing 11, and the front wall 16 lof the latter has a plurality of small openings or perforations 23 formed therethroughl to permit the passage of a predetermined amount of additional or-secondary air into the combustion space around the said outlet pipe. Obviously for different installations where the volume of the combustion space `varies and diierent amounts of' oil are to be burnt the number and size of these openings 23 must vary.
The operation of the burner is as follows: The
' 23 that sufficient air passes through the casing 11 to keep the outlet pipe 12 cool. Therefore if any oil falls from the tip 19 onto the pipe 12 after the burner is extinguished it does not form into hard carbon, but remains in a liquid state and is blown into the combustion chamber as soon as the burner is re-started.
While in the foregoing the preferred embodiment of the invention has been described and shown, it is understood that the invention is susceptible to such alterations and modifications as fall within the scope of the appended claims.
What I claim is: l
l. In an oil burner, the combination of an air tube, a casing through the front wall of which one larger and a plurality of smaller openings are formed, the rear wall of the casing also having an opening therethrough into which the air tube extends, an air outlet pipe extending forwardly from the tube and supported thereby, the front extremity of the outlet pipe being mounted in the larger opening formed through the front casing wall, said tube and outlet pipe being relatively so arranged as to permit some of the air from the formerv toaenter the casing and pass through the smaller openings through the front wall, an oil feed pipe substantially centrally positidned in the air outlet pipe, a burner tip on the extremity of the feed pipe, means for feeding oil into the feed pipe and through the burner tip, and means for delivering air through the tube.
2. In an oil burner, the combination of an air tube, a casing through the rear Wall of which said tube extends, the front wall of the casing having one larger and a plurality of smaller openings formed therethrough, an air outlet pipe extending into the tube and having one end supported in the larger opening, means supporting the outlet pipe in the tube so thatv the major portion of the air passing through the latter is discharged through the outlet pipe While some air enters the casing and passes through the smaller openings in the front wall, an oil feed pipe in said outlet pipe, a burner tip thereon, means for delivering air into the tube, and means for delivering oil into the feed pipe.
3. In an oil burner, the combination of an air tube, a casing having aligned apertures formed through itsfront and rear walls and a plurality of smaller openings also formed through the front wall, said tube extending through and supported by the aperture formed through the rear casing Wall, anair outlet pipe concentric with and smaller than said tube having its front extremity mounted in the front casing aperture, the rear extremity of the outlet pipe extending into -said tube, means supporting said outlet pipe in said tube so that an annularpassage is formed from the tube into the casing around the outlet pipe, an oil feed pipe extending substantially centrally through the tube and outlet pipe, a burner tip on the feed pipe adjacent the front of the casing, a spider around the feed pipe Within the outlet pipe, fixed blades on said spider to impart a swirling motion to air passing through the outlet pipe, the outer margins of the blades resting on the bore of the outlet pipe, a fan, a pump, and means for driving the fan and the pump, said tube being connected to the fan, and the oil feed pipe to the pump discharge.
4. In an oil burner, the 'combination of a casing having two apertured walls, an air discharge tube mounted in one wall aperture and terminating within the casing, an air outlet pipe mounted in the other wall aperture and terminating at one extremity adjacent the air tube but spaced therefrom so that a large part of the air delivered through Vthe tube passes through the outlet pipe and' the rest of the air passes into the casing, an oil feed pipe terminating in the air outlet pipe adjacent its extremity remote from the air tube, a burner tip on the oil feed pipe through which oil is delivered, the air outlet pipe discharging air around the oil delivered from the burner tip, and the casing wall in which the air outlet pipe is mounted being perforated to permit air to pass from the casing around the outlet pipe and burner tip to relieve any partial vacuum that wouldl otherwise be caused there by combustion.
5. In an oil burner, the combination of a casing having aligned openings formed through its front and rear Walls, an air tube mounted in the rear wall opening and terminating in the casing, an air outlet pipe mounted in the front wall opening and extending into the tube so that an annular passage is formed around the outlet pipe to permit some air to enter the casing from the tube, the front wall of the casing being perforated around the outlet pipe, an oil feed pipe in the outlet pipe terminating adjacent, the front extremity of the latter, and a burner tip on the oil feed pipe positioned so that air discharged from the outlet pipe mixes with oil discharged from the burner tip while other air passing through the perforations relieves the partial vacuum that would otherwise be caused by combustion adjacent the front of the outlet pipe and burner tip.
