Description

Sept. 13, 1955 G. N. PALlvos FLUID MIXER Filed April 15, 1953 @(000000) 00OOO frayer-$71' George N .Palit/05 United States Patent pad FLUID MlXER George N. Palvos, Chicago, lli. Application April 15, 1953, Serial No. 349,010 4 Claims. (Cl. 13S-37) This invention relates to a fluid mixer such as, for example, a device frequently known as a faucet aerator normally used in kitchens, laundries and the like for producing a jet of water containingair bubbles disseminated throughout so as to cause the jet to become whitish in appearance and soft and light to the touch.

See also my pending application Serial Number 321,977 filed November 22, 1952.

The present invention aims to provide an improved device of this character, and, in some respects, an improvement upon the device of my pending application above referred to.

The invention will be understood by reference to the following description, taken together with the accompanying drawing, of an illustrative embodiment thereof, and in which drawing- Figure l is a view of a faucet or the like having the invention of the present application applied thereto;

Figure 2 is an axial sectional view of the device of the present invention, parts being shown in elevation;

Figure 3 is a composite view of the internal parts of the device, in separated relation and in the order of their occurrence in the complete assembly;

Figure 4 is a section taken on the line 4-4 of Fig. 3; and

Figure 5 is a plan view, in development form, of a perforated strip from which is formed one of the parts of the device shown in Fig. 3.

Referring in detail to the illustrative construction shown in the drawing, numeral 11 refers in general to the tluid mixer device of the present invention, associated, for exemplication, with the faucet 12 which may be a faucet such as is commonly found in household kitchen sinks, laundry tubs, and the like, and having at its outlet end a male thread 12a. The device 11 comprises a casing 13 which may be of any suitable material such as metal or plastic, and is here indicated to be of metal. T he casing 13 at its upper end is internally threaded as at '13a to mate with the thread 12a of the faucet, which extends into the casing approximately down to a shoulder 14 therein. Disposed along the sides of the casing 13 are ports 15 for the entry of a fluid such as gas or air, and in this instance air, into the interior of the casing.

Following the disclosure of my said pending application l show in the casing 13 a break-up or dispersal element, for a fluid such as water, formed in the shape of a cup-like member 16 having a cup portion 17 and an annular flared rim or flange 18. The cup portion 17 is formed by a central dished portion of reduced diameter providing a wall 19 spaced from but parallel with the flange 18 and joined thereto by an annular or cylindrical wall 20, the annular wall 20 having perforations 21 therein spaced about or around its periphery.

The ange 18 is of a diameter just sucient to be received within the thread 13a of the casing and to rest upon the shoulder 14 to which it may be clamped to hold the dispersal member 16 in position in the casing by the faucet 12 when the device 11 is screwed thereon.

"ffice As here shown and further following the device of my pending application, the dispersal member 16 is disposed with its cup portion 17 extending downwardly in the casing or toward the outlet or downstream end thereof and with its cup portion 17 spaced from the wall 13 of the casing opposite the ports 15. Disposed between the cup portion 17 of the dispersal member and the wall of the casing, and spaced from both, is a deilector ring 22 having a cylindrical wall 23 and an annular dished flange 242i, the deector 22 being shown located in the casing between the dispersal member 16 and the annular shoulder 14 in the casing and held thereto by the clamping of the parts together as already described, the deflector annular wall 23 thereby being disposed between the ports 15 and the perforations 21 of the dispersal member but spaced from both.

Turning now to the improvement of the present invention, I have shown the passageway 25 of the casing widened intermediately as at 26 from adjacent its proximal end 25 and further additionally widened as at 27 adjacent its distal end 28. The casing 13 and particularly the intermediate bore portion 26 is adapted to receive from its distal end 28 the auxiliary and finial dispersal elements of the device next described.

Turning now to a description of the elements just referred to and taking them in the order of their occurrence from the region of the proximal end of the casing toward its distal end, I first dispose in the casing reduced bore portion 26 a wheeldike member 29, this member being wheel-like in the sense that it has a hub 3d, feliy 31, and radial spokes 32. Preferably there are sixteen of the radial Spokes 32 in the wheel member 29, equally spaced apart circuniferentialiy of the hub and felly, and forming between them sixteen segmentai slots 33, as in wheel fashion. The felly 31 of the wheel-like member 29 is of a diameter to tit snugly in the intermediate reduced bore portion 26 of the passageway 2i? of the casing.

Next in order toward the downstream end of the casing, is the wire screen 34, `which is preferably disposed between the wheel-like member 29 and the part next described.

Lastly, if place in the passageway, the auxiliary iinial break-up or dispersal member 35 which I have referred to herein for convenience and facility of description as a honeycomb member. The unique honeycomb member 35 is, as seen from Fig. 5, advantageously formed from a strip of soft metal, such, for example, as copper, a fragment of which is shown at 36 and having therein uniformly spaced rows of perforations 37 arranged longitudinally and transversely of the strip. The strip 36 is of a sufcient length so that it may be bent around upon itself into the rosette form best shown in Fig. 3 at 38, this being a rosette form in the sense that the strip or ribbon Se is bent sinuously to form the bows or foliations 39 and in the form of an annulus about the imaginary center of the member, these foliations forming sectors of the device and each providing a segmental slot 40 of which there are desirably twelve in the complete annulus or rosette which the member describes. The strip 36 may have one free end as at 41 and the radial element or barrier 42 of each foliation laps the adjacent radial element of the adjacent foliation so that they are of laminated form in the return-bend or sinuous winding of the ribbon 36. When the complete annulus has been formed, the remainder of the strip or ribbon is bent around the outside of the segmental foliation or bow sectors, as at 43, and the free end of this, as at 44, may terminate adjacent the initial end 41 of the strip but on the out side or opposite side of the foliation.

As best seen in Fig. 4, the member 35 has its perforations 37 spaced and arranged both radially of the member and axially thereof, thus providing a honeycomb effect, the axial extent of the member being such as in this case to provide for three axially aligned perforations in each. Furthermore, the peripheral loop 43 of the member 35 has perforations S7 therein which are arranged and spaced apart both axially of the member and peripherally thereof.

The honeycomb member 35 is arranged to have an overall diameter such that it fits snugly into the intermediate reduced part 26 of the passageway 2S of the casing, and, as so constructed and arranged, the honeycomb member 35 is of a resilient or springy character so that it may he slightly compressed to be inserted into the bore 26 and whereby after insertion it will expand slightly and grip the walls of this bore section of the passageway, thus not only retaining itself within the bore but also retaining therein the wheel-like member 29 and the screen 34.

By reason of the counterbore or further enlarged portion 27 of the passageway 25, the casing 13 at its distal end 2S is spaced from the honeycomb member so as to provide an annular space 4S between the distal end of the casing and the honeycomb member.

So constructed and arranged, a stream of water passing through the faucet l2 in the direction of the arrow 46 toward the downstream end of the casing, will be broken up into dispersed or discrete streams of water into which air is entrained through the ports l5 of the casing, thus forming a stream constituting a mixture of water and air. Thereupon, in accordance with the present invention, this already mixed stream of air and water strikes the wheel-like plate 29 which acts upon it to disintegrate the stream somewhat into sixteen parallel axially moving currents. The force of these currents is somewhat reduced by the screen 34. Next, the sixteen discrete currents of water strike the honeycomb member 35, and, since the latter has only twelve segmental slots therein, the Sixteen discrete streams or currents of mixed water and air are now reduced to twelve.

This reduction in the number of streams of mixed water and air causes a further breaking up o r mixture of the air and water, and this is nally completed by the passage of the mixed air and water through the perforations 37 of the honeycomb member 35, the stream passing back and forth through lthese perforations so that it is completely broken up and dispersed and a jet of water and air issues from the distal end 28 of the casing containing a maximized amount of air bubbles thoroughly disseminated throughout so as to cause the jet to be lghtish in appearance and soft and light to the touch, and preventing splashing when the stream hits an impinged surface, as well as contributing to economy of use of soap or the like, and of hot water, the use of which by the present invention is minimized while attaining a high degree of eciency thereof.

The invention is not intended to be limited to details of construction shown for purposes of exemplication,

and furthermore, it may not be essential at all times that all features of the invention be used conjointly, various combinations and sub-combinations being at times advantageously employed.

Such changes may be made as fall within. the scope of the appended claims without departing from the invention.
