SPRAY-BURNER.

To all whom it may concern:

Be it known that I, ARCHIE T. Rice, a. citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Spray-Burners, of which the following is a specification.

This invention relates to oil burners used in connection wit-h fuel oil furnaces in which the oil is atomized by an agitator, then forced into the burners, where the hydrocarbons evolve combustible gases which, when heated to incandescence, form the fiame.to be used.

The principal object of this invention is to provide improved means for uniting the hydrocarbons of the fuel with the oxygen of the air that is forced into the furnace through the burner from the bellows or other suitable pressure supply. p

\Vit-h these and many other objects in view which will morereadily appear as the nature of the invention is better understood,

the same consists in the novel construction,

combination and arrangement of parts as hereinafter will be more fully pointed out, illustrated and claimed.

in the accompanying drawings Figure 1 is a longitudinal sectional view of the improved burner showing the combined cylindrical and cone shaped sections of the burner. Fig. 2 is a section taken on the line -2-2 of Fig. 1. and shows the air motor for Fig. 3 is a view taken on the line 3-3 of Fig. 1, and shows the oil agitator inverted, the same being driven by the air motor shown in Fig. 2.

Similar nmncrals refer to corresponding parts throughoutthe several figures of thedrawings. Referring to Fig. 1 of the drawmgs, tlfe air from the bellows enters the burncz I through the pipe 10 while air under higher pressure is forced through the pipe 11, thus Specification of Letters Patent.

into a foam or spray, thus breaking the oil globules up into atoms and in this state conducted by the pipe 16, through the opening 17 into the wide mouthed cylindrical focusing chamber 18, which is preferably suspended on the longitudinal center line of the main blast pipe 19.

The forward end 20' of the chamber 18 is contracted so as to insure each atom of the oil striking the diverging cone or spreading element-21, which is attached to the upper side '22 of the focusing chamber 18, by a bracket 23, as shown in F ig'. 1 of-the drawings. The finely divided oil leaving the outer periphery at the be so of the cone 21 is mingled with the air, from the bellows or other'pressure supply, which is brough to the burner through the pipe 10. The hydrocarbon of the fuel oil, uniting with the oxygen of the air, forms a combustible mixture, which when ignited is heated to producing a clean flame of high temperature.

The auxiliary funnel 2 1 is a frustum of a cone the base 25 being attached at its upper face to the inside of the blast pipe 19 while its lower ed e is free from the pipe thus allowing a 521st of air to continually pass between theinside of the blast pipe and the outside of the base of the frustum, through the opening 26 as shown in Fig. 1 of the drawings. It isthus seen that any oil adhering to the auxiliarycon'e will bepic-ked up by this current and carried into the zone of combustion, thus obviating the loss of any 'fuel oil that is so common the ordinary types of oil furnaces.

Without further description it is thought that the many advantages of the herein described invention are readily apparent.
