01L BURNER.

Specification of Letters Patent.

Application filed September 3, 1920. Serial No. 407,876.

To all w 710m it may 00410 7 07,:

Be 'it known that I, JOHN DINGIROGLOU, a citizen of Armenia, residing at Portland, in the county of Multnomah and State of Ore on, have invented a new and useful Oilurner, of which the following is a specification.

This invention aims to provide an oil burner which may be operated either at high or low pressure, means being provided whereby the nozzle of the burner may be cleaned at the will of an operator, the burner being peculiarly eflicient in the matter of consumption of fuel.

A mechanic, proceeding within the scope of what is claimed, may exercise the skill of his calling in the direction of making alterations, without departing from the spirit of the invention.

In the drawings :Figure 1 shows in longitudinal section, a burner embodying the Invention, parts being broken away, and parts appearing in section; Figures 2, 3 and 4 are sections taken, respectlvely, on the lines 22, 3-3 and 4.4 of Figure 1.

The burner comprises a tubular body 1 provided at its forward end with a diaphragm 2, the body having an end wall 3 and being supplied, adjacent to the wall 3 with a partition 4,-there being a neck 5 conmeeting the partition with the end wall and opening through the end wall. The part1- tion 4 and the end wall 3 define a fuel chamber 6 surroundin the neck 5, the body 1 having a fuel in et 7 communicating with the chamber.

A nozzle 8 of tapered form is threaded at 9 upon the forward end of the body 1, or is secured thereto otherwise, the nozzle having an outlet 10. A pipe 11 is disposed in the axis of the body 1 and has its ends mounted in the diaphragm 2 and in the partition 4, the pipe establishing communication between the neck 5 and the nozzle 8. The numeral 12 marks a fuel conduit disposed in sinuous or spiral form about the pipe 11, the ends of the conduit being mounted in the diaphragm 2 and inthe partition 4. The conduit 12 establishes communication between the fuel chamber 6 and th nozzle 8.

The end walls 3 of the body 1 carries an outstanding nipple 14 into which is threaded the neck 15 of a closure plug 16 which abuts against the outer end of the nipple. A cap 17 is threaded on the plug 16 and encloses a packing 18. A cleaning rod 19 is mounted for reciprocation in the pipe 11, in the plug 16 and in the cap 17, the rod having a push button 20 at its rear end. An abutment 21 1s mounted on the rod 19 and is located in the neck 5.. A compression spring 22 surrounds a port-ion of the rod and engages the abutment 21 and the partition 4.

In practical operation, the spring22 serves to retract the rod 19 with respect to the outlet 10 of the nozzle 8. When pressure is applied to the rod 19 b way of the button 20, the rod 19 may be a vanced so that the forward end of the rod will enter the outlet 10 of the nozzle and remove any foreign matter which may have lodged in the outlet. The fuel enters by way of the inlet 7 and, traversing the annular fuel chamber 6, enters the conduit 12, the fuel passing from the conduit into the nozzle 8 and burning at the outlet 10, the outlet constituting a combustion orifice. Owing to the sinuous form of the conduit 12, the fuel is given a whirling movement in the nozzle 8 and is finely diyideg. before it finds an exit through the out- If desired, the closure plug 16 and the rod 19 may be removed. Then, air or steam under pressure may be supplied through the nipple 14, the pressure fluid traversing the neck 5' and the pipe 11 and being delivered into the nozzle 8, along with the fuel. The construction is such, obviously, that the burner may be operated at high pressure or at low pressure.

An oil port 50 is formed in the diaphragm 2, a port 51 being formed in the partition 4, the ports preferably being located diametricall opposite to each other. The oil, procee ing from the chamber 6, enters the space about the conduit 12, and flows into the nozzle 8, owing to the fact that the ports 50 and 51 are provided. There is a continuous circulation of oil, and the conduit 12 is prevented from overheating.

I claim:

1. An oil burner comprising a tubular body having a rear end wall and provided with a forward diaphragm, the body being supplied, adjacent to the end wall, with a partition, there being a neck connecting the partition with the end wall and opening through the artition and the end wall, the partition an the end wall defining a fuel chamber surrounding the neck, the body having a fuel inlet for the chamber; a

nozzle on the forward end of the body; a pipe having its ends mounted in the diaphragm, and in the partition, the pipe establishing communication between the nozzle and the neck; and a sinuous fuel conduit having its ends carried by the diaphragm and the partition, the conduit establishing communication between the chamber and the nozzle.

2. An oil burner constructed as set forth in claim ,1 and further characterizedby the provision of a cleaning rod for the nozzle, the cleaning rod being slidable in the pipe and in the neck.

3. An oil burner constructed as set forth in claim 1, and further characterized by the provision of a cleaning rod for the nozzle, the rod being slidable in the pipe and in the neck, means being located in the neck for retracting the rod with respect to the nozzle. 4. An oil burner constructed as set forth in claim 1, and further characterized by the fact that the diaphragm and the partition are provided with ports affording a circulation about the conduit.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
