LIQUID-ATOMIZER.

Specification of Letters Patent.

Application filed June 12, 1911.

Patented Nov. a, 1911; Serial No. 632,711.

To all whom it may concern.

Be it known that I, KNUT M. DAHL, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented a new and useful Liquid-Atomizer, of which the following is a specification.

The object of my present invention is to devise a novel atomizer wherein liquids such as crude oil, water or any other desired liquid, may be atomized and wherein the only agent employed for this atomization is the pressure of the liquid.

Viith the above end in view, my invention consists of a novel construction of a liquid atomizer.

It further consists of a novel construction and combination of a holder, an atomizer disk, a tip and novel means for securing the parts in assembled position.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a sectional elevation of a liquid atomizer embodying my invention. Fig. 2 represents a sectional elevation of the tip in detached position. Fig. 3 rep resents a sectional elevation of the atomizer disk in detached position. Fig. 4 represents a plan view of the atomizingdisk.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :1 designates a body or holder to which is removably secured a conduit 2, which, in the present instance, has one end threaded as indicated at 3, thereby adapting the same to engage with stance and which, when the parts are in assembled position, is adapted to extend into the bore 5 a desired distance. The disk 10 is provided with a laterally extending annular flange 12 which is provided with one or more apertures 13, it being understood that the inner face of the flange 12 is adapted to seat against the end'of the holder 1, which is faced ofl as indicated at 14. The front face of the disk 10 is provided with an extension 15 in the shape of a cone.

16 designatesone or moreports or passages which extend tangentially from a port 13 to the cone 15, it being best seen from Fig. 3 that at the base of the cone there is an annular groove 17 which extends slightly into the'front face of the flange 12.

18 designates a tip which is provided at its rear end with a lateral extending flange 19 which is adapted to close the front end of the ports 13 when the parts are in'as sembled position, the forward end of the tip 18 being adapted to pass through the flange 9 of the clamping nut 8. The tip 18 is internally recessed asindicated at 20 in such a manner that the recess is given the form of a cone which communicates with an outlet or discharge port 21 extending through the forward end' of the tip. The walls of the discharge port 21 are angularly inclined to the walls of the conical recess. 20. In order to assemble the parts, the atomizer disk 10 is placed on the end of the holder 1, the tip 18 is then placed upon the disk 10 and the clamping nut 8 is secured in posi tion so that the shoulder 22 formed by the flange 9 of said clamping nut 8 will engage the flange 19 of the tip 18 and thereby cause the tip 18 and the atomizing disk 10 to be secured in assembled position with respect to the holder 1.

The operation of my novel atomizer will now be apparent and is as follows The liquid ,under pressure entering through the passes tangentially to the cone 15, thereby causing the liquid to receive a rot whirling or centrifugal motion as it pass through the conical passage 23 and the discharge p t 9.1. of the tip 18, and owing to the cen frugal force the liquid 'is discharged in the form of a fine spray, as is evident.

it will be apparent to those skilled in this art that when it is desired to inspect the dish 10 or remove the tip 18, this may be r v accomplished by removing the c .i 3; nut B whereupon all the parts are accessible for the purpose of cleaning, inspection. or repairs.

in as 1 am aware, I am the first in the art to devise an, atomizer wherein the liquid is forced under pressure tangentially against a cone so that as it passes from the tip of the atomizer there is imparted thereto a rotary, whirling or centrifugal motion of the character described so that the centrifugal force will cause the liquid to be ejected from the discharge port in the form of a fine spray, and it is to be understood that my claims to such features are to be interpreted with corresponding scope.

The number of ports 13 and 16 employed Will vary in accordance With the conditions and requirements met with in practice.

It will now be apparent that I have devised a novel and useful construction of a liquid atomizer which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing auy'of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is z 1. A nozzle comprising a body with an covered portion of said passage en 0 out; r i tangentially, and in one I01 uoitin cited parts.

2. A noznl flaring enit, provided communicat lying said it said 1 recess receiving; i cit-no and charge port leading from said recess, said recess tangentially, and means ing the recited parts.

3. In a device of the character described,

a nozzle comprising a body with a flaring exit 6, a disk 10 ov'erlving said body and provided with a rearward extension iii, a cone l5, a iertures 13, and passages 16 extending tangentially to said cone and terniiinating in proximity thereto, a tip 18 overlying said disk and covering: a portion of said passages and provided with a coniso cal recess 20 receiving said cone, and a dis-' charge port leading from said recess, and means for uniting the recited parts.

4:. In an atomizer, a body having an inlet thereto, a disk at one end of said body and 35 having a port 13 connecting; With said inlet, said disk having" a cone at its forward end and a passage 16 tangential to said cone and communicating with said port, said disk having near the base of said cone an annular groove 1? also connnunicating with said passage 16, a tip having a discharge port and a conical shaped recess in communi ation therewith into which said cone extends, and means for rigidly securing said tip, disk and body in assembled position.
