SPRAY-NOZZLE.
Specification of Letters Patent.
Patented May 11, 1920.
Application filed March 5, 1918. Serial No. 220,516.
To all whom it may concern.-
Be it known that we, THOMAS V. MURPHY, a citizen of the United States, and WLADYS- LAW CZARNKCKI, a citizen of Poland, residing in Philadelphia, Pennsylvania, have invented Spray-Nozzles, of which the following is a specification.
One object of our invention is to provide a substantial and inexpensive device for finely dividing liquids such as water, oil, acid, etc, when these are supplied either under high pressure or in connection with some other fluid under pressure such as air or steam; the various parts being of such design as to permit of their being easily and quickly cleaned.
It is further desired to provide a spray nozzle which while having relatively large and therefore easily cleaned passages or channels, shall have these so disposed and formed that there shall be but a relatively small flow of liquid through them under given pressure conditions.
Another object of the invention is to provide a nozzle of such construction as to be particularly adapted for manufacture out of porcelain or stoneware in order that while being acid-proof, it shall at the same time be relatively inexpensive as well as durable.
These objects and other advantageous ends we attain as hereinafter set forth, reference being had to the accompanying drawin s, in which igure 1 is a longitudinal vertical section of a multiple nozzle for forming a series of concentric sprays or finely divided bodies of igs. 2 and 3 are respectively a plan and a side elevation of the deflecting element for the upper nozzle structure of the device shown in Fig. 1; and
Fig. 4 is a plan of a deflector element of the lower nozzle structure of Fig. 1.
As shown in the above drawings the nozzle consists of a body portion 28 shown as internally threaded, for attachment to a liquid supply conduit. Said body at one end is also externally threaded for the attachment of a nozzle cap 29 having a relatively large central opening 30 and designed to hold a deflector element 31 immovably seated within the end of the body 28. This structure 31 has a central tubular extension 32 concentric with which it is formed with a flat outer face closely fitting against the with the interior of the body 28 through tangentially entering channels 34 and edge channels 35. Since the extension 32 is concentric with the cover 29, there is provided an annular delivery opening in line with the annular recess 33 through which liquid from the interior of the body 28 is discharged after passing through the edge channels 35 and the face channels 34.
The outer end of the extension 32 is threaded for the reception of a second nozzle cap 36 which has a central delivery opening 37 and holds a second deflecting element 38 against the end of the extension. This element is formed with a central curved recess 39 entered by tangentially disposed passages 40 supplied from the interior of the extension 32 through edge passages 41 formed in the element 38. When therefore, liquid is supplied to the body 28, it likewise passes through the extension 32 and is delivered into the recess 39 from the channels 40 in such manner that it is caused to rapidly rotate, being discharged through the end opening 37 in the form of a sheet or hollow body made up of finely divided or practically atomized particles concentric with the finely divided body of liquid delivered through the opening 30 of the main nozzle cover 29.
While we have illustrated the deflector elements as having a plane face with a central recess and passages formed to enter the latter tangentially although this result may be attained by ribs 42 placed tangentially to the central recess 39 (Figs. 2 and 3), since these coact with the cap to form passages d0 which as required, are generally tangent to the circularly curved central recess. The essential feature of the invention resides in the provision of these passages in an otherwise fiat or plane surface which may be easily faced or ground when the nozzle is made of porcelain or the like, where a coni cal or angular surface could not be commercially made on a body of this material to fulfill the desired conditions.
l/Vith the construction shown, there is practically no erosive action caused by the' liquid passing through the nozzle when the latter is made of earthenware, nor is it damaged by such corrosive liquids as sulfuric acid, for example. Moreover with the construction shown, the various passages may be cleaned or opened with the utmost ease in case they become clogged with solid material as obviously the act of taking the nozzle apart will render all of them accessible.
Owing to the peculiar disposition and form of the channels they may be made of relatively large cross section so as to not easily become clogged and yet deliver a comparatively small quantity of finely divided liquid in a given time at any particular pressure, as is required under certain conditions in the manufacture of sulfuric acid, for example.
We claim: a
1. The combination in a nozzle structure of. a hollow body having a flat interior surface provided with an outlet opening; a deflector element also having a flat surface engaging said surface of the body and including a tubular projection extended through the opening of said body, there being an annular cavity in said element ex tending around said extension and coinmu-nicating with the interior of the body through channels entering it tangentially; a cap for said extension having a fiat face and a central outlet; and a second deflector element held to the extension by the cap and provided with a flat face engaging the flat face of said cap, said latter element being formed with a central recess having channels in communication with the hollow of the extension and entering said cavity tangentially.
2. The combination in a nozzle of a plurality of superposed deflector elements each having a plane face formed with a recess and passages entering the same tangentially; with a plurality of structures having plane surfaces respectively engaging the plane surfaces of said deflector elements and provided with concentric delivery openings for discharging the liquid delivered to the adj acent recesses through the tangential passages respectively.
In witness whereof we aflix our signatures.
