s. E FEGLEY on BURNER July 8, 1930.

Filed Feb. 5; 1927 2 Sheets-Sheet 2 INVENTOR. C7677? zzei Z1759? 30 in the accompanying Patented July 8, 1930- SAMUEL E. IEEGLEY, F LANCASTER, PENNSYLVANIA on. BURNER Application filed February 3, 1927. SerialNo. 165,613.

This invention relates to oil burners and v has special reference to an improved oil burner arranged to produce a fine mist of oil through the proper intermixing of oil and air. i 7

One important object of the invention is to provide an improved means of vproducingan initial nebulizing of the inflowing oil. I A second important object of the inven- V tion is to provide improved means for regulating the initialnebulizing effect.

A third important object of the invention is to provide an improved burner wherein primary. and secondary nebulization of the 15 oil will be effected, the secondary nebulizing means further reducing the size of .the already minute globules of oil produced by the primary nebulizing means by breaking these globules into fractional portions.

,fourth important object of the invention is to'provide means for maintaining the oil as secondarily nebulized in the high state of nebulization produced- 'bythe secondary nebulizer.

" With the above in other objects in V ew as willbe hereinafter apparent, the inven-o tion consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated drawings and specifically claimed.

In the accompanying drawings like char-' acters of reference indicate like parts in the several views, and:

Figure 10 is'a section on the line Figure 9.

is a section on the line 88 of Figures 11 and12 are face views of modi fied forms of the jet disks.

VJhile the invention is capable-0f many v and various embodime'nts but one is shown in the present drawings wherein it will be seen that the burner is provided with a body 10 wherein is a mainhbore. 11 terminating forwardly in a reduced portion. 12 having its v front end closed except for an outlet port'13 so that this end forms a valve seat. The body is provided with a lateral air inletport 14 so that an air pipe 15 may be connected ,7

to the body and airvdelivered in the bore 11.

The rear end of the bore is threaded and to the rear of the threaded portion is provided a stuffingbox 16 having a packing gland 17.

Extending through the stuffing box is an oil supply tube 18 having a threaded'portion .19 engaging the threads of the bore so that rotation of this tube will cause longitudinal movement in the body, a handle 20 being provided to effect this rotative movement. The

forward end of this tube is closed by a tip 21 having a plurality of rearwardly inclined ports 22 which open into the space surround.- ing the tube and either into the smaller front portion of the bore or behind the abrupt shoulder 23 into the larger portion of the bore according to the position giventhe oil supply tube.- Thus the 'flow of oil maybe retarded or allowed freedom of passage. This part of the device forms a primary nebulizer, "the air stream flowingjforwardly meeting the; fine -oil jets issuing from the ports 22 in arearwardly inclined direction and breaking the oil up into a mist so that thenebulized. oil may flow out of the port 13. Moreoverthe front end of thetip 22 .forms a valve which cooperates with the valve seat before mentioned to regulate the flow of nebulized oil and'airthroughlthe Screwed into the front end of the body and forming a forward extension thereof is a nozzle 24: wherein is held a multiple armed spider 26 supporting a shortaxially eXtending shaft 28. On this shaft is mounted a nebulizing wheel 27 having a series of ports 28 therein and carrying inclined blade portions 29 extending over these ports on the front face of the wheel. Thus the primarily nebulized oil passes through the spider and ports 28 and, strikin the blades 29, causes rapid rotation of the secondary nebulizing wheel and thus breaks up the already small globules of oil into exceedingly minute frac tions.

Forward of the wheel 27 and spaced therefrom is a diaphragm 30 having ports 31 inclined as shown to produce a sw rling action on the nebulized oil and air flowing therethrough and thus preventing segregation of the oil in the forward part of the chamber.

The forward end of the chamber is closed by a jet dish 32 having one or more ports 33 of any desired shape or arrangement therein and these ports may either lead straight through the disk as in Figure 1 or may be shaped to guide the mixture of oil and air at an angle to the burner as shown in Figures 9 and 10. gasket 34 supported on the fronte or the nozzle and held thereon by a clamping ring 35, the disk being provided with positioning pins 36 so that it may be adjusted to bring the port or ports 33 into desired position.

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within '1 w L ages the scope claimed.

Having thus described the invention, what is claimed as new, is:

1. In an oil burner, a body having a bore therein provided with an air inlet and having an outlet end, an oil supply tube arranged axially of the bore and havingits forward end closed and forming a valve, said oil supply tube having a plurality of ports opening laterally through its side wall and located in advance ofthe air inlet, said outlet end of the body forming a valve seat, for said valve, saidbody having at its forward end an enlarged chamber, a multiple spoked spider fixed transversely of the said chamber, anebulizing wheel revolubly associated with said spider, said nebulizing wheel having a plurality of ports and being provided with deflector blades on its forward face projecting over said wheel ports, and a This dish rest on a,

ported jet disk closing the forward end of said chamber.

2. In an oil burner, a body having a bore therein provided with an air inlet and having an outlet end, an oil supply tube having its forward end closed and forming a valve, said oil supply tube having a plurality of ports opening laterally through its side wall and located in advance of the air inlet, said outlet end of the body forming a valve seat, for said valve, said body having at its for ward end an enlarged chamber, a multiple spolred spider fixed transversely of the said chamber, a nebulizing wheel re'volubly associated with said spider, said nebulizing wheel having a plurality of ports and being 'irovided with deflector blades on its for.- ward face projecting over said wheel ports, ported jet disk closing the forward end of said chamber, and a diaphragm fixed bet *eei the nebulizer wheel and the jet disk .nd provided with a plurality of ports pEiCQCl from the center of the diaphragm nd inclined to produce a swirling action of ie nebulized oil in the space between the .iaphragm and jet disk.

3. In an oil burner, a body having a bore herein providen with an air inlet and having .11 outlet end, said body having at its forward end an enlarged chamber, a multiple spoked spider fixed transversely of the said chamber, a nebuiizing wheel revolubly associated with said spider, said nebulizing wheel having a plurality of ports and being pr vided with defl ctor blades on its forward face projecting over said ports, a ported jet disk closing the forward end of said chamher, and a diaphragm fixed between the nebulizer wheel and the ct disk and provided with a plurality of ports spaced from the center of the diaphragm and inclined to produce a swirling action of the nebulized oil in the space between the diaphragm and jet disk. 7

In testimony whereof I affix my signature.

SAMUEL E. FEGLEY.
