Application mea February 11, 1926. serial N0. 87,561. i

- The present invention relates to an oil burner, and has for its object to provide a structure which will thoroughly atomize and aerate the oil so as to form substantially a combustible gas which when'ignited will create a.hot.blue flame.

Another very important object of the invention is the provision of a burner of this nature which is exceedingly simple in its construction, capable of being manufactured at a lovi1 cost, yet lproving thoroughly rel liable in use and well adapted to the purpose for which it is designed.

Another very important object of the invention is to provide a burner o-f this nature which is very compact in its construction, and which is. capabe of easy ladjustment, a'nd is not likely to easily become out of order.

With the above and numerous other objects invi'ew as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination andarrangement of parts as 'willbe hereinafter more fully described and claimed.

In the drawing i Figure 1 is a longitudinal section through the burner embodying the features of my invention, 1 T

Figs. 2, 3 and 4 are transverse sections taken substantially on the lines 2 2, 33, and 4-4, respectively of Figil.

Referring to the drawingin detail, it will be seen that the-"letter A designates generally a shell of a tubular formation, having v one portion 5 greater in Idiameter than the remaining portion 6. A bore 7 is provided to extend longitudinally ofthe shell A and is restricted as at 8'to provide a beveled interior shoulder or sea't. A recess 10 is ,providedadjacenty thel reduced portion v`8-1of the bore for the reception -of a nipple the" bore of which' is dividedA into a re atively large portion 12 and a relatively small' portion 13, referringto the'diametersthereof.

-Thel outera end of the nipple L1 is closed as is indicated-at 14j, the interior face being of a conical formation so that orifices 15 may be projected radially therethrough.

The (portion of the nipple 11 adjacent the close end 14 is reduced and externally threaded as is indicated at 16, so that a eupshaped cap 17 is threadedly engaged thereover. y

I "Ihe closed end of the cap 17 is provided with an orifice Yl8 coaxially arranged with the bore 7. A tube 20 is provided with an enlarged externally threaded open end portion 21( while the other end thereof is closed and beveled as at 22, said closed end being provided with a co-axial orifice 23. The enlarged portion 21 threadedly engages with threads provided in the interior vof the bore 7 so that the other portion of the tube 20 may exend in the bore with its exterior surface spaced from the'interior surface of said bore. The outer en d 25 of the tube is internally cthreaded for the reception of a coupling 26 leading from a suitable air line 27. The lar er portion 5 of the shell A is provided wit a transverse passage 28 leading int-o the bore 7, and adapted toereceive a 1coupling 29 to be connected to a source of o1 I a Air and oil are fed to the -couplings 26 and 29 'respectively under pressure. The oil fills upthe .bore 7 through the passage 28 and the air is shot intoY the oil through the orilice 23, thereby forcing the oil throughv the restricted portion 8 of the bore and commingling therewith. When the com-mingled oil and air enter the nipple 13, they. are mixed to a considerable extent and are forced radially out through the orifices 15 so as to'set up a sort of Whirl within the cap 17 and are then linally re- `jected through the orifice 18 which is right angularly disposed in relation to the orifices `From actual experience I have found that the jet of aerated oil projectedl through the orifice 18 is really in theform of a-combustible gas, because this burner so eiliciently and A.effectively breaks'up the oil and allows the vaporization thereof and thorough aeration thereof, which is so desirable in the burning of oil to obtain the maximum efficiency. 'I e device is exceedingly compact and su prising smalll` for' the work which can be accomplished therewith.

It is thought'that the construction, oper'- ation, advantages of this invention' will not be clearly understood and appreciated by .those skilled in this art without a more ldetailed description thereof. The present elhbodiinent of the invention has been disclosed in detail nierelyby way of example, since in actual practice, 1t attains the features of advantage enumerated 'as desirable inthestatement of the .inyention and the above description. 'f

lll

It will be apparent, however, that numerous changes in the details of construction, and in the combination and arranged of parts and in the sizes of the parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new isz- An oil burner of the class described in- `cluding a shell having a longitudinally eX- tending bore, a tube mounted in the bore of the shell and having a portion thereof spaced from the interior of the bore to ploy vide a Well for the reception of oil, said shell being provided with an opening permitting the ingress of the oil to the Well, the inner end of said tube being closed and provided with a relatively small coaxially arranged orifice, and a nipple in the end of the shell and adjacent vthe closed end of the tube and having radially extending orifices in a closed end, and a' cap threaded over the closed end of the nippleand provided with a cone-shaped interior surface on its end wall, said end Wall having an orificevextending coaxially with the first meni tioned orifice and through the apex of the cone-shaped inner surface.

ln testimony whereof l aliix my signature.
