OIL BURNER.

Specification of Letters Patent.

Patented Mar. 21, 1922.

Application filed March 22, 1920. Serial No. 367,899.

T o allwiwmit may concern:

Be it known that I, ALBERT T. NEWMAN, a citizen of the United States, residing at Em oria, in the county of Lyon and State of ansas, have invented certain new and useful Improvements in 'Oil Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to oil burners and particularly to means for vaporizing the oil whereby the oil vapor will be mixed with air in order to effect the most efiicient combustion ofthe fuel.

The invention contemplates means whereby the incoming fuel oil may be subjected to heat intense enough to transform it into a gaseous condition prior to being ignited and, thereb effect an econom in the consumption of the fuel since gasi ed oil mixed with air will produce a more intense heat than is possible when the oil is directly converted into heat without first passing through a vaporizing or gasifying zone.

In the drawings,

Fig. I is a sectional view through a burner constructed in accordance with my invention, and

Fig. Ill is a disassociated view of the burner, showing the inner member of the gasifying means in elevation and the outer member in section.

In carrying out my invention, I prefer to employ an an delivery device consistlng of a conical member 1, having a relatively large central orifice 2, through which the air may pass, and the member 1 is shown as provided with at. outwardly and upwardly curved flange 3 to provide a circumferential groove 4 to receive oil for priming. The conical member 1 is provided with a plurality of shoulders 5, illustrated as three in number, and these shoulders constitute steps to receive the base of the inner conical member 6 of the vaporizing device.

The member 6 is adapted to be seated upon the steps or shoulders 5 and it is in the form of a truncated cone, in the top of which is provided a circumferential oove 7, and

35 there is a plurality of longitu inally extending ribs or spacing members 8 about the perimeter of the cone and these ribs intersect the circumferential grooves 9 formed in the outer wall of the member 6. The groove 7 is formed by the end wall of the member 6 and a boss 10 in the end thereof, which is provided with an opening 11 to receive the end of the fuel pipe 12, whereby fuel may pass into the groove 7 and flow over the walls of the members 6, as will be presently explained.

The cover or outer conical member 13 is provided with a heat transmitting flange 14 and said member is spaced about the member 6 by the ribs 8 to form the wall of the member 13, corresponding in shape with the walls of the member 6 but being large enough to the burner. As soon as the walls of the members 6 and 13 become sufliciently heated, the oil will be vaporized in gaseous form, the valve 16 being then manipulated to provide the proper mixture, it being understood that the air .suppl will be substantiall constant in the oil an the gas supply will have to be regulated to rovide the most eflicient mixture, the con ition-of which can be readily determined by observation.

After the gaseous vapor is formed and the burner is in action, the walls of the members 6 and 13 will become quite hot and the heat absorbed by the member 13 will be distributed to the heat thereof and conveyed to the chamber formed by the groove 7 through the depending flange 14 so that the oil initially discharged from pipe 12 will be quickly raised to a relatively high temperature, t en as the oil flows over the wall of the member 6, it willbe vaporized, the rooves 9 serving to retardthe flow of the 011 so as to insure efiicient heat penetration to effect the vaporization thereof. The result will be that the fuel will be admitted in a circular sheet against the wall of the groove 4 and by bein deflected, will create a partial vacuum in t e space 17 formed between the cone 1 and the inner surface of the wall of the member 6, assisting the flow of air through the openings 2 to supply the necessary oxygen to support combustion.

shells constituting a vapor generating space, and means for supplying oil to said space.

2. An oil burner comprising an inner shell having horizontal grooves in its outer wall, longitudinall disposed spacing ribs on the outer wall 0 the shell, an outer shell sup ported upon said ribs, the space between the shells constituting a vapor generating space, and a grooved primer in line with and below the shells.

In testimony whereof I aflix in Si nature.

ALBERT T. N W AN.
