I'NVENTOR d9 Thomas JLoftizs Arman; 7



A'roMIzERI To all whom it may concern Be it known that I, THOMAS J. Lor'rUs, a citizen of the United States, residing at Castella, in the county of Shasta, and State of California, have invented new and useful Improvements in Atomizers, of which the following is a specification.

This invention relates to an atomizer.

One of the objects of the present invention is toprovide a simple form of fuel atomizer particularly adapted for use in connection with internal combustion engines of the type shown in my former application entitled Explosive engines, issued J anuary 1, 1916, Patent No. 1,166,999.

Another object of the invention is to provide-an atomizer which is operated by compressed air or steam and which is so constructed that the air and fuel nozzles may be adjusted with relation to each other.

Another object is to provide a pair of screens to insure a further breaking up of fuel particles which have not been thoroughly atomized by the nozzles and furthermore, to provide means for trapping and returning unvaporized fuel to the source of supply, or removing it from the vaporizer.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings in which the figure is a vertical longitudinal section through the atomizer.

Referring to the drawings in detail, A indicates in general a casing which is centrally divided. to form two sections indicated at 2 and 3. These sections are flanged as at 4 and secured together by means of the screws 5. The two casing sections secured together as shown, form an interior chamber 6, which is large in diameter near its center and contracted at both ends. Formed in the contracted end of the section 3 is a threaded opening which is adapted to receive a nozzle 7 which is connected with a source of air or steam supply under pressure not'here shown, a valve 8 being provided to regulate the fiow of air through the nozzle. Formed on the lower side of the section 3 is an internally threaded extension 9 and mounted in said extension is a nozzle 10, to which fuel oil is adapted to be delivered througha pipe 11 connected with a suitable source of supply not here shown. Carried Specification of Letters Patent.

by the nozzle 10-is a needle valve 12 of Slllt', able construction which regulates the discharge of the oil nozzle. Formed near the largest diameter of the section 3 is an open ing 13 which is connected by means of a pipe 14 with the source of fuel oilsupply previously referred to but not shown. This pipe serves the function of an over-flow or return, hereinafter to be described. Formed in the section2 is an annular shoulder for the reception of a pair of screenmembers 15 and 16. These screens are separated by a spacing ring 17 and are secured in the position shown when the sections 2 and 3 are secured together. or outer end oft'he section 2 is a threaded extension 18 and screwed into said extension is a pipe 19 which is adapted to convey the atomized combustible mixture to any point desired.

Patented Dec. 12, 1916. Application filed May 31, 1916. Serial No. 100,938.

In operation, it is only necessary to open" the valve 8 to permit a desired volume of air under pressure to discharge through the nozzle 7 this nozzle being positioned at right angles to the oil nozzle 10 and discharging across the point of the same, causes a suction which draws the fuel oil up through Y thepipe 11 and past the needle valve 12 and through the nozzle point into the chamber 6, where it is broken up by the action of the air discharging from the nozzle 7. A combustible mixture is thus formed, which passes through the screens 15 and 16 and out through the pipe 19. The provision of the screens 15 and 16 is one of the important features of the present invention as they positively break up any fuel particles which have not been thoroughly atomized by-the action of the nozzles 7 and 10. Another important feature is the shape of the casing sections shown. The fuel and air are admitted at the contracted end .of the chamber 6, and the mixture is then permitted to porized material to drain and return back to the source of supply previously described.

The device constructed as here shown is particularly adapted for use in connection with the intcrna combustion engine shown in my former application, entitled Exlosive engine, issued January 4, 1916,

atent No. 1,1 66,999, but may also be used for other purposes. Any grade of oil desired may be used and may in some instances be heated before admitted to the nozzle 10. The adjustable mounting of the nozzles 7 and 10 permits these to be moved to and from each other, and therefore permits a perfect breaking up or atomization of the fuel oil admitted.

The materials and finish of theseveral arts of the invention may be such as the udgment and experience of the manufacturer may dictate.

I wish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims, and that I do not wish to limit myself to the specific design and construction here shown.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1. An atomizer including a casing formed in two sections, each section having its outer end interiorly threaded and having its inner end flanged, means to secure the flanges in abutting relation, a lateral integral interiorly threaded exten ion on one of said sections, an oil supply pipe extending laterally into said extension, an oil nozzle secured in said extension, an air valve threaded in the outer end of the section having said extension, a screen clamped between said inner ends of the sections, and an oil drain pipe extending into the inner end of said section having the extension and located between the screen aud oil nozzle) 2. An atomizer including a casing formed in two sections, the sections having their inner ends similarly flared, means to secure the flared ends together, a screen at approximately the juncture of said flared ends, an air nozzle and an oil nozzle secured to the outer end of one section, the oil nozzle being disposed at right angles to the air nozzle, the other section being flared at its outer end similar to the Hare of its inner end.

8. An atomizer including a sectional casing, one section being contracted at its outer end and flared at its inner end, atomizing means in said contracted end, the second section-being convexed on its interior between its ends so as to form each end thereof with a flare which gradually merges into the convexed part, means to secure the inner ends of the sections together whereby a central enlarged chamber is provided by said inner ends of the sections, a screen extending across the center of said chamber, and a pipe connected to the outer flared end of the second section.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
