12 Claims.

This invention relates to a bubble fountain device, and more particularly to a device for attachment to an ordinary water outlet, such as a faucet, to permit the faucet to be used as a bubble fountain whenever desired without interfering with the use of the faucet for normal purposes.

In accordance with my present invention, I provide a device comprising a bulbous casing having an adapter for attachment to a water outlet, faucet or the like, and having a combination spout and valve adjustable with respect to the casing to divert water from the easing into the valve and spout and thus convert the faucet into a bubble fountain. The spout-valve combination is so arranged as to be movable into a position such as not to obstruct the ordinary passage of water through the casing when the water outlet is being used for other purposes than to provide a bub-bier. Means are also provided for effecting the automatic movement of the spout-valve combination into through-passage-opening position whenever the water outlet is opened up full, thereby preventing against excessive pressure of water causing spurting of the water from the spout.

It is therefore an important object of this invention to provide a bubble fountain device for attachment to any ordinary water outlet, such as a faucet or the like, for converting such outlet into a bubble fountain whenever desired, while at other times not interfering with the normal through-flow of water from the outlet.

It is a further important object of this invention to provide a bubble fountain device having a combination spout and valve that is semi-automatic in its action to prevent objectionable spurting of the water from the spout when the full force of water at the outlet is turned on.

It is a still further important object of this invention to provide a bubble fountain device having a spout-valve combination that controls its operation as a bubbler and that is so constructed and arranged as to automatically be rendered inoperative as a bubbler when full water pressure is turned on.

Other and further important objects of this invention will be apparent from the disclosures in the specification and the accompanying drawings.

On the drawings:

Figure 1 is a side elevational view of a bubble fountain device embodying the principles of my invention, installed upon a faucet.

Figure 2 is a longitudinal sectional view of the device taken substantially along the line II-II of Figure 4, showing in dotted lines the operation of the spout-valve combination.

Figure 3 is a sectional view taken substantially along the broken line III-III of Figure 2,

2 illustrating in dotted lines the tilting of the bubbler spout.

Figure 4.- is a sectional view taken substantially along the line IV-IV of Figure 2.

As shown on the drawings the reference numeral Ill indicates generally a device embodying the principles of my invention, which device is shown in Figure 1 as attached to the end of an ordinary faucet ll. Said device Ill comprises a bulbous casing I2, which may suitably be formed of plastic, metal or other material, and which is provided with a passage l3 extending axially therethrough. An adapter l4, suitably formed of relatively soft sheet rubber, is attached to said casing at the upper end of said passage l3 and is provided with a reduced opening it for receiving the end of the faucet II. The adapter l4 thus serves by frictional engagement with the faucet end to attach the device lil' thereto.

Said through passage l3 provides at its upper end an enlarged cylindrical recess it, against the bottom of which is positioned a screen or filter I'l. Below said filter ll, the through passage !3 is intersected by a transverse bore I8, having a closed inner end [80. and opening through the casing wall at one side thereof, as at I9.

A hollow cylindrical valve, indicated generally by the reference numeral 20, is slidably and rotatably mounted in said bore H with its end 2| projecting therefrom. A spout 22 is integrally formed with said valve 20 and extends upwardly and at a slight angle from the outer end 2! thereof. The spout-valve combination may be integrally molded from a plastic, or may be made of other suitable material. Alternatively, the spout and valve may be formed separately. In that case the valve may be slidable, only, while the spout may be so connected to the valve as to be tiltable without rotating the valve but movable with the valve as the latter moves into open or closed position.

The valve 26 has a cylindrical cavity 23 that is closed at its inner end by a closure 2t and that is in flow communication with the interior 25 of the spout 22. The end surfaces of the valve 29 are cut away as at 2B and at 26a so that when the valve is in the closed position illustrated in full lines in Figure 2 the passage 13 above said valve is uncovered, as at 21, to permit water to flow into the end of the blind bore l8 back of the valve. The purpose of this will be explained later. A thin slot 28 in the upper cylindrical wall of the valve 20 affords reduced flow communication between the passage l3 above said valve and the interior 23 of the valve. Water can thus flow through said slot 28 into the interior of the valve and out through the spout 22 when the device is used as a bubbler.

Means are provided for limiting the axial sliding movement of the combination spout and valve. Said means comprise a wide longitudinally extending groove 29 in the under side of the valve 20 and a threaded stop member 30 extending through the lower wall of said casing 12 into said groove. As shown in Figure 2, when the spout-valve assembly is in the full-line position closing the passage l3, the threaded stop member 30 abuts against the righthand end of the groove 29, as viewed, and the slanting end wall 26 abuts the end wall [80. of the bore {8, thereby limiting the further inward movement of the valve 20. In the dotted line position shown in Figure 2, however, the threaded stop member 30 abuts the lefthand end of the groove 29 to prevent further outward movement of the valve 20. It will also be noted that in the closed position of the valve 29 the upper portion of the passageway l3 above the valve 20 is uncovered to provide an entrance 2'! into, the blind end of the bore l8 behind said valve. Should the faucet H be opened up wide while the valve is in the closed position shown in Eigure 2, the pressure of water in back of the valve 29 would act against the end wall 26 to shove the valve over to its open position as indi- Qated in dotted lines and thus permit the full flow of water through the passage 13 and shut off flow through the valve-spout combination, the opening 28 being covered when the spout-valve combination is in its righthand position.

Consequently, whenever excessive pressure develops While the valve is closed, the valve is automatically opened to prevent spurting of water out of the spout 22. The stop 30 in cooperation with the, groove 29 limits the outward movement of the spout-valve combination under these circumstances.

Means are also provided for permitting the spout 22 to be tilted into either of the positions illustrated in dotted lines in Figure 3. The purpose of this is to accommodate the person usin the bubbler, depending upon whether such per.- son is approaching the bubbler on the right or lefthand side. Such means include a plurality, three as shown, parallel grooves 3!, 3m and 3lb (Fig. 3) formed along the lower external surface of the valve 28 and terminating short of the extremity of the exposed end 2! of the valve. A detent 32 is provided for cooperation with anyone of said grooves 3!, 31a or 3H). Said detent 32 comprises a spring metal finger secured at one end, as at 33 to the lower portion of the casing l2, and having a rounded lug 34 extending upward from its free end for riding in one of said grooves.

By. reason of the resiliency of the detent 32:, the. lug 34 can be easily displaced from any one of the grooves 3|, 31a or SH), and the valve-spout combination moved in either direction until the lug 34, again falls into a groove. In this connection, it is noted that the groove 29 is of suflioient width to permit this limited swiveling movement of; the. valve 20.

Because of the provision of the adapter hi, my bubble fountain device may be attached to any ot the usual water outlets, regardlessof the diam: eter of the outlet or whether threaded or not. Qrdinarily, whenever the bubbler device is not in use, the spout-valve combination will be in its outward position, as indicated in dotted lines in liligure 2. When in such position, there is an un-, obstructed flow of water, when the faucet is turned on, through the passage 3, and the outlet can be used for any of its usual purposes.

When, however, it is, desired to convert theoutlet into a bubble fountain, the spout-valve combination is moved to its inward position, shown in full lines in Figure 2, and the faucet ll opened gradually until the desired height of fountain is playing from the spout 22. In this case, the flow of water is downwardly through the screen H and the upper portion of the passage i3, through the opening '28 into the interior 23 of the valve 20 and thence up through the passage 25 in the spout 22.

If, accidentally or otherwise, the faucet H should be turned on too full while the device I0 is being used as a bubbler fountain, the pressure of water behind the valve 20 will, as previously described, force the spout-valve combination over to its extreme righthand position, as indicated in dotted lines in Figure 2 thereby shutting off the fountain from the spout 22 and reestablishing full flowcoin'munication through the passage l3.

It will, of course be understood that various details of construction may be varied through a wide range without departing from the principles of this invention and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
