  • the concave shape of the disc 51 serves to direct any accumulation of dirt particles toward the center of the disc thereby leaving the majority of the perforations in the disc free from clogging.
  • the upstream disc and the downstream disc may each have thirty to forty perforations each of eighttenths to one millimeter in diameter. While an upstream disc is not absolutely essential, its use regulates the flow ⁇ of liquid to the downstream jet-forming disc and collects dirt in the liquid which might otherwise clog the perfor-ations of the downstream disc.
  • the upstream disc may have larger perforations than the downstream disc but in such case the large perforations should be spaced more than one millimeter from each other, or the upstream disc may have perforations of equal or smaller size than the perforations of the downstream disc and closer to each other.
  • the upstream disc may be provided with a central imperforate portion to provide for more even distribution of liquid to the downstream disc.
  • the upstream disc yperforar-tions should be such as not to materially increase the back pressure due to the attachment of the mixing device to a water faucet since a material restriction to the free ilow of liquid through the mixing device, when excessive, will damage the quality of the bubbly jet of liquid produced. It is desirable that the downstream disc produce a plurality of high velocity streamlets of liquid parallel to one another or slightly divergent.
  • the perforated discs may be spaced about one millimeter apart by washers, as shown in the Figures 3 and 4. construction, or by the conguration of the downstream disc as shown in the Figures 5, 6 and 7 construction.

  • the discharge outlet opening of the mixing device should be about fifteen to twenty millimeters in diameter for use on the average water supply faucet.
  • the mixing unit chamber is formed by members tu and 6i;
  • the member 60 preferably formed of resilient material such as rubber, is provided with an inturned inlet neck 63 having a space 64 between it and the outer portion of the member, a plurality of integral webs 6E being provided therein. Liquid under faucet pressure hows into the space S4 to cause the neck 63 to grip the spout end of a faucet.
  • the lower end of member 60 is provided with projecting ribs $5 and the inner surface of member 6I frictionally engages the outer surfaces cf the ribs 5S.
  • the ribs 66 provide air inlet channels for the admission of air into the chamber containing the mixing unit.
  • the mixing unit comp-rises a pair of perforated discs 5l and 68 resiliently held in an annular channel in the lower portion of member G.
  • the disc Sl is preferably of curved cross-section with the convex side facing upstream. The convex surface of the upstream disc will direct dirt toward its periphery and tend to keep the perforations open.

  • the washers 'i8 may be provided with a few radially projecting arms to prevent a decrease in the spacing between screens 'il'.
  • the upper perforated disc 8B may be conveniently formed from plastic material or metal and is provided with an integral .peripheral rim 8
  • is adapted to serve as a gasket to seal the mixing unit in a faucet connecting member.
  • An element such as the disc provides in one piece a disc-spacing shoulder or washer, the upstream perforated disc, and the washer sealing the space between the fluid mixing device and the end of the spout.
  • the screen assembly shown in Figures 9 and l0 comprises three fine-mesh screens E held together by a peripheral rim member B.
  • the screens 85 may be formed of woven wire fabric in which certain spaced wires 81 are of substantially larger diameter than the remaining wires of the fabric.
  • the large diameter wires Bl serve to properly space the screens 85 apart when the screens are assembled on one another.
  • Another method for spacing the screens is illustrated in Figure 1l wherein a single screen 90 is shown.
  • the screen is of fine-mesh woven wire which is corrugated to form a screen having reverse curvature as shown.
  • the screens 9U may be of concave shape similar to the shape of diaphragme 51 and 61 to provide spacing when two concave screens are used together.
  • each screen 95 is formed to have a plurality of depressed areas or nubs 98.
  • the spaced depressed areas 96 on one screen engage flat area-s on the adjacent screen to space the screens a proper distance apart.
  • the member for holding a mixing unit assembly is secured to the spout end of a faucet or pipe by threads as shown in Figures 1, 2, 3, 4 and 6 or by friction as shown in the Figure '7 construction.
  • the entering solid stream is divided into a plurality of high velocity streamlets by the pair of perforated discs.
  • the upstream disc functions to prevent dirt from clogging the downstream disc and also to assure a more even distribution of liquid to the downstream disc.
  • the downstream disc then divides the liquid flow into a plurality of high velocity fine streamlets which draw air into the mixing chamber through the air inlets described.
  • the liquid streamlets impinge upon the upstream ne-mesh screen which breaks up the streamlets and intimately mixes the liquid with air. Further mixing is eifected by the downstream screens which cause a coherent stream of liquid having a myriad of air particles and small air bubbles entrapped and suspended therein to issue from the discharge outlet.
  • the resulting stream of liquid has a relatively large volume of gas, such as air, intimately mixed therewith, and is white in appearance, soft and light to the touch, and possessed of numerous advantages not found in the usual jet of liquid discharged from a conventional faucet or tap.
  • the bubbly foaming stream may be used to form soap suds rapidly with relatively little soap. The foaming stream clings to objects placed in its path without splashing and facilitates cleaning and rinsing operations.
  • the bubbles swell the stream and increase the contact between the liquid and the obj ect placed under the stream, thereby speeding up cleansing and rinsing operations. As a result, the stream washes in less time and with less liquid.
  • the air bubbles in the foaming stream carry away foreign tastes and odors and restore 7 yoxygen to the liquid.
  • the mixing unit is particularly suitable for use on water faucets, but is also useful in mixing a gas with a liquid, in general, as will be apparent to those skilled in the art.
