1 A/ 4 A x AERATOR DEVICE Julius A. Hjulian, Palos Heights, 11]., assignorto Crane Co., Chicago, 111., a corporation of Illinois Application February 10, 1953, Serial No. 336,113 9 Claims. (Cl. 261-115) The invention relates to an aerator device and constitutes modifications and improvements over the subject matter covered in my pending patent application pertaining to similar devices and identified by Serial No. 333,577, filed January 27, 1953.
As brought out in the application identified by the above serial number, it has long been a problem to provide an aerator device such as that used to aerate water, for example, discharging from a kitchen sink faucet spout because of the prior uses of air inlet ports communicating with the atmosphere by transverse ported extension through the walls of the faucet spout or casing and frequently leading to the creation of an unsanitary condition at the spout discharge limits.
There has also been the strong objection that because of the earlier employment of screens superposed and positioned in transverse relation to the path of flow clogging eventually has resulted to render the device virtually useless for the purpose and, of course, seriously interfering with the desired capacity or volume of discharge from the faucet or other device upon which the aerator is installed.
Therefore, as in the case of my co-pending application, it is an important object of this invention to provide a novel aerating device in which both of the objectionable conditions above referred to are eliminated and in addition to provide an aerator which is relatively economical to manufacture, and which maintains itself in workable condition almost indefinitely and may be easily installed, inspected or removed as desired.
Other objects and advantages of this invention will become more readily apparent upon proceeding with a description of preferred forms as per the accompanying specification and read in light of the drawings, in which Fig. l is a fragmentary magnified assembly view of a preferred embodiment of the invention.

nited States Patent 0 2,754,097 Patented July 10, 1956 Referring now to Fig. 1, it should be noted that the aerator of this invention comprises essentially such parts as an imperforate conduit or spout 1, threadedly provided as at 2 to receive a body 3, which body is imperforate between the inlet and outlet thereof and which in combination with the spout 1 forms conduit means which is imperforate to the open outlet end of the body 3, the said body at the lower portion having a flow guide memher 4, as illustrated. From a shoulder 5 therewithin a diffuser generally designated 6 is mounted. Diaphragm means preferably in the form of a relieved or apertured disc 7 is received within the bore 10. The disc rests upon shoulder 8, the apertures 9, annularly arranged, all combining to serve as passages for the flow of liquid therethrough in a manner as hereinafter described at greater length. At the end of the conduit, an annular gasket 12 is interposed so as to make a fiuid tight seal between the end surface 13 of the conduit and the inner end surface 14 of the diffuser 6. It has been found that the diffuser member 6 should preferably be formed as a basket or cup-shaped receptor, and in the form herein disclosed, it will fins 11, 15, and 16, preferably extending radially inward from the outer periphery of .the diffuser portion 17 as illustrated. They are designated: those 11 are horizontal but 16 are bent at 22 /2" angle and 15 are bent at 45 angle. The general arrangement of such fins is more clearly shown with respect to their radial extension in Fig. 2, and while a number of the fins, such as 16, may extend in the plane indicated, they may, of course, be differently arranged and shaped, depending upon the service and the size .of the member with which the aerator is associated. Therefore, it is a matter of choice as to the angle at which the ribs or fins 15 and 16 are bent toward the center and the staggered pattern of generally frustoconical form may therefore vary quite substantially from that illustrated without detracting from the function of such arrangement.
Similarly, as to the apertures velocity into the diffuser strainer, these forms also may change. However, it should be understood that by the intensive and high velocity flow of water through the above described orifices 9 and subsequently through jets passing through the orifices 9 will strike and impinge upon the fins 11, 15, and 16 immediately therebelow, as shown. The diffuser at its lower end portion is preferably, but not necessarily, provided by shape and length of fins 11, 15 and 16 with a central aperture 19. connection with the .turbulence referred to, a vacuum-like condition appears to be created Within and about the chamber 18 to the extent of requiring an air replacement therewithin .at the locations referred to and this is effected by a counterfiow of air apparently induced by guide member 4, preferably but not necessarily, used, a unique flow pattem is Provided in which the discharging stream largely formed at the central aperture 19 causes the drawing in of air at peripheral points and in some cases annularly 3 around the wall surface 23 The cellular construction 22 may be supplemented by continuing the wire formation, as more clearly shown in Fig. 2, to include cells extend ing across the opening as at 24 and 25. In the structure shown, the How guide substantially extends across the discharging aperture of the chamber formed by the Wall 23 to aid in giving greater stratification of the discharging stream, which preferably is a continuous soft coherent flow.
In some cases, as shown more clearly in Fig. 3, the disc member or diaphragm may be made with relieved notches of greater arcuate dimensions as shown at 26 to direct flow downwardly from an annular position. In all other respects, the structure may be similar to that shown in Figs. 1 and 2.
Fig. 4 is same as Fig. 2, except the central aperture 19 is eliminated by extended fins 11 to the center to close the passage, and each fin 11 is stake-pointed to form an unbroken or closed center.
In Figs. 5 and 6, a diffuser, such as 27, may be of substantially depending cylindrical form, such as 28, and provided with the radially extending fins of variable length and angle, such as at 29, 30, and 31, the longest prongs being 32, next longest 29, next and short prongs 31. Similarly, a solid center is again formed, the has extending diametrically across as shown. The discs shown in Figs. 2 or 3 may also be used with this form of diffuser without inconvenience although a disc is not absolutely essential. The diifuser 27 is supported in the manner described in connection with Fig. 1. In this structure, it has been found that because the angles of the radially extending fins 29 through 32 are not so pronounced as that described in connection with Figs. 1 and 2, there may be even greater turbulence within the chamber 18 thereabove. The form of flow guide used may be similar to that shown in Figs, 1 and 2 or in some cases here, too, it may be dispensed with.
In Fig. 7, another modification of a diffuser is shown in which the conduit or spout discharge 1 is supplied with an aerator body 3, similarly attached as at 2 by means of the threads or other suitable arrangement and the gasket 12 as well as the apertured disc 7 is assembled therewith as shown. However, in this modified construction, a plurality of superposed difiuser members, as shown more clearly in Figs. 8 and 9 and designated generally 33, have spaced openings 34 and 35 and lower depending fingers 36 adapted to be received at their lowermost installation or support upon the shoulder 37 of the body 3. The fingers of the remaining superposed portions are received within the relieved portions 35 as shown to form a nest of dilfusers, to provide for the turbulence within the chamber 38 as well as within the annular spaces 39.
While a flow guide 4 is shown in combination therewith, it will be understood that under certain conditions it may be dispensed with.
In Fig. 10, a further modified form is shown in which the diffuser is shoulder mounted on the body 3 on the surface 14 thereof, as shown, and the diaphragm or how interrupting member 48 preferably assumes a frustoconical form provided with the annularly arranged apertures 49. It is held in clamped relation with the conduit 1 by means of the threads 2 employing the gasket 12 generally bearing against surface 13 in the same manner as described in Figs. 1 and 2. The diffuser 51 is provided with radially extending fin portions 50, 52 and 53 extending so as to form a chamber 54 and an upper and lower aperture 55 and intermediate aperture formed at 56. The usual flow guide 4 may be used or dispensed with as desired. An additional feature of this construction lies in the ability to control the volume of the water passing through the apertures 49 by means of the threaded conical diverter member 57 having the head 58 of frustoconical form so as to merge closely with and form the annular chamber 59 as illustrated. Thus, it will be clear that by the mere insertion of a small screw driver engaging the slot 61 of the head 57 and rotating the latter as desired, the space 59 may be adjusted accord ingly. Here, it will be apparent a simple and efiective means for throttling the flow into the diffuser chamber 18 is thus relatively easily accomplished.
Fig. 11 is top plan view of diffuser of Fig. 10.
In Fig. 12, an additional modified form is shown in which the only variation from that shown in Fig. 1 is that instead of having the conduit 1 threaded with outside exposed threads, it is internally threaded as at 42 to receive the body generally designated 43, the latter member at 44 being shouldered to receive the diffuser 6 following the details of Figs. 1 and 2. The flow guide in this form may differ from that of Fig. l in that it is preferably of a form provided with the cells 45 and does not extend across the full opening as indicated beyond chamber 46 in Fig. 13. The arrangement of the fins on the diffuser 6 is similar to that of Fig. l. The gasket 2 is clamped in fluid sealing relation against the disc 7 by means of the threaded bushing 47.
While several embodiments have been described herein, of course, it should be clear that a number of other structures falling within the terms of the invention may be suitably provided, and therefore, the spirit of the invention should be measured by the scope of the appended claims.
