Description
' Dec. 18, 1956 E. P. AGHNIDES GAS AND FLUID MIXING DEVICE Filed Feb. 18; 1953 FIG 2 INVENTOR ELIE P.AGHNIDES BY M M ATTORNEYS United States Patent This invention relates to gas and fluid mixing devices and more particularly to means for aerating liquids of the type shown in my prior U. S. Patents Nos. 2,210,846 (granted August 6, 1940) and 2,316,832 (granted April 20, 1943).
One object of this invention is to provide an improved 2,774,584 Patented Dec. 18, 1956 "ice The scope of my invention is being defined in the appended claims.
I claim to have invented:
1. An aerator having a casing with an inlet end adapted to be connected to a source of liquid under pressure and a discharge end, a ledge in the casing adjacent the discharge end, screen means resting on said ledge comprising a cylindrical shell having inturned lips at both ends thereof, substantially flat screens at each end of the shell respectively and bearing on the two lips respectively, a middle screen interposed between the other two having a plurality of raised and indented radial portions to space the screens from each other, an inverted cup perforated at its top and sides and resting on said shell, an apertured disc upstream of the cuphaving a rim which is wider on one side of the upstream disc than on the other side, said upstream disc being connected to its rim but separate from the other parts wherev by it may be placed in the aerator either with the wide aerator adapted for useover a wider range of pressures than would normally be possible.
Another object of this invention is to provide an improved aerator in which the connection between the aerating device and the faucet is watertight when connected to a faucet.
Still another object of the invention is to provide, in an aerator, improved screen means which is safer, more readily constructed, and which cannot get out of order during use thereof.
In the drawings:
Figure l is a sectional view of one form of the invention.
Figure 2 is a plan view of one of the screens used with the device.
The aerator of Figure '1 follows the teachings of my prior patents and of the commercial practices in the art except as disclosed below. A casing 10 has a ledge 11 on which a shell 90 rests. An inverted cup 13 having perforations in its top and side walls rests on the top of shell 90. Casing 10 has air inlet slits 10a to allow air to enter the ports in the side of inverted cup 13. Casing 10 also has internal threads or other suitable means for attaching it to a faucet. The top 14 of the inverted cup 13 acts as means for breaking up the flow into a plurality of individual high velocity streamlets. However, it is usually desirable to provide two parallel perforated diaphragms at the upstream end and therefore I also provide perforated disc 17 mounted in a rim 1516. The upper part 16 of the rim is wider than the lower part as shown. The rim 15-16 may be placed in the casing 10 with either the wide part 16 upward or the narrow part 15 upward. Reversing the disc 17 is useful as in some circumstances the aerating device is more perfectly sealed to faucet if the disc is reversed. Moreover, when the wide rim 16 is down it closes the outer ring of holes in diaphragm 14 and thus increases the velocity of flow in the remaining holes which of course is an advantage when the faucet pressure is too low.
The shell 90 carries three screens 91, 92 and 93 in it. Shell 90 has lips 94 and 95 at its respective upper and lower edges to hold the screens in place. The middle screen 93 (a plan view of which is shown in Figure 2) has three radial portions 96 raised and three radial portions 97 indented, whereby to hold middle screen 93 parallel to and spaced from screens 91 and 92.
The wires of which the screen is woven are attached together at each cross-over by welding, cementing, soldering, or by other means, as more fully explained in my copending application Serial No. 337,502, filed on even date herewith and entitled Faucet Attachments.
part of the rim upstream or downstream of the narrow part thereof, said cup having air inlet holes in its side wall and the casing having air inlet holes feeding air to those in the cup whereby to supply air for aerating the water.
2. A faucet attachment including a casing having internal threads to connect it to a faucet, perforated means in the casing, and washer means resting on the perforated means, said washer means having a perforated disc covering the opening in the washer, rims on both sides of the washer, the rim on one side of the washer extending radially inwardly to a greater extent than on the other side thereof, both rims being attached to the washer.
3. A device for producing a jet of water containing air bubbles comprising a chamber the inlet end of which is adapted for connection with the discharge end of a faucet or the like and the outlet end of which is adapted to discharge said jet, an apertured diaphragm at the upstream end of the chamber through which water is adapted to be forced into the chamber with substantial velocity, an air port opening into the chamber through which air is induced by the water delivered from the apertured diaphragm, means in the path of the water after it leaves the apertured diaphragm and before it discharges at the outlet end for finely breaking up the water and mixing it with air to form a coherent jet having bubbles, a second apertured disc upstream of said apertured diaphragm and having a channeled rim thereon acting as a washer, said washer resting on said diaphragm and having a flange on both sides thereof, both flanges ex tending from the periphery of the washer inward with one thereof extending substantially further inward than the other.
4. A device for producing a jet of water containing air bubbles comprising a chamber the inlet end of which is adapted for connection with the discharge end of a faucet or the like and the outlet end of which is adapted to discharge said jet, an apertured diaphragm at the upstream end of the chamber through which water is adapted to be forced into the chamber with substantial velocity, an air port opening into the chamber through which air is induced by the water delivered from the apertured diaphragm, means in the path of the water after it leaves the apertured diaphragm and before it discharges at the outlet end for finely breaking up the water and mixing it with air to form a coherent jet having bubbles, a second apertured disc upstream of said apertured diaphragm and having a double-flanged rim thereon acting as a washer, said washer resting on said diaphragm and having a flange on both sides thereof, both flanges extending from the periphery of the washer inward with one thereof extending substantially further inward than the other, said apertured diaphragm having a plurality of apertures that are never covered by either flange and a row of apertures that are covered and closed by the said wide flange when said washer has the wider flange against the diaphragm and are not closed by the narrow flange when the narrow flange is placed against said diaphragm.
'5. A faucet attachment comprising a casing having means to connect it to a faucet, a first perforated means in the casing, a double flanged channel shaped spacer means resting on the perforated means, said spacer means surrounding and holding a second perforated means between its double flanges, one flange being sufficiently wide to cover an outer group of holes in said first perforated means when contiguous thereto, the other flange being narrow enough to uncover said group of holes when contiguous thereto, said narrow flange having suflicient thickness to space said second perforated means from said first perforated means to permit water to flow through said group of holes left uncovered when said narrow flange is contiguous to said first perforated means.
6. The combination set forth in claim 5, said first perforated means having a peripheral flanged skirt extending downstream and forming 'a mixing chamber, air holes in said flanged skirt and a screen element positioned downstream of said flanged skirt.
7. The combination set forth in claim 6, said screen 4 element comprising a ring having inwardly extending portions serving to retain a plurality of screens therein, one of said screens containing indented portions serving to space the screens from each other.
