     FIELD OF INVENTION  
       [0002]     The field of the invention is water filtration devices.  
       BACKGROUND OF THE INVENTION  
       [0003]     The demand for pure water continues to grow rapidly due to increasing concerns about the quality and safety of tap water, the popularity of water as a beverage (instead of soda and alcohol) and the growing awareness that most people do not drink enough water as prescribed by the medical community.  
         [0004]     Water is supplied from municipal water systems (many of which are aging), private water systems and wells in the United States. Frequently, this water has poor taste, particulates, unwanted odors and in many cases contaminants contained in it. Municipal water is commonly treated with chlorine to eliminate bacterial contaminants. Chlorine adds what most people feel is an unpleasant taste and odor. Water conditions vary greatly according to the geographic area and therefore travelers may also experience these problems as they visit hotel and motel rooms around the country. It is desirous to remove bad tastes, odors, sediment and contaminants before ingesting the water or using it for cooking food.  
         [0005]     Water treatment devices of many varieties have proven effective in accomplishing water purification. Generally these devices work through chemical and mechanical actions that remove contaminants and impurities from water. These filters have a finite life. Sediment can eventually clog a filter and chemical reactions realized through adsorption (carbon media) and ion exchange (cation resin) have a limited capacity.  
         [0006]     U.S. Pat. No. 5,989,425 to Yonezawa et al. discloses a multi-way valve and water purifier. The multi-way valve is disclosed as a small-sized one which may be used with a small-sized water purifier. The device disclosed in the &#39;425 patent is a faucet mounted filter and it is designed for removing and exchanging valve bodies.  
         [0007]     U.S. Pat. No. 5,017,286 to Heiligman and U.S. Pat. No. Re. 35667 to Heiligman disclose a vertical filter enclosed in a housing and the housing is supported by a duct. The vertical filter may be permanently secured to the filter by hot melt adhesive which renders the filter non-removable. Further, the vertical filter may be pre-wrapped with a porous paper pre-filter. The device disclosed in the &#39;286 patent is a faucet mounted filter. If the filter is glued to the filter housing the filter housing must be removed and discarded together with the filter. A new filter housing (and filter) must then be mounted onto the duct of the diverter valve each time the filter housing is replaced. This involves time consuming labor in the case of each embodiment disclosed in the &#39;286 patent. In one embodiment of the &#39;286 patent, the filter housing is secured by a retaining clip. In another embodiment disclosed in the &#39;286 patent, the male duct of the filter housing is press-fit into an opening in the diverter valve. Alternatively, the male duct of the filter housing may be affixed to the diverter valve by a U-clip, cotter pin or the like. The filter housing as disclosed in the &#39;286 patent is disclosed as residing vertically in front of the faucet. In short, it is not a simple matter to change the filter housing of the device disclosed in the &#39;286 patent.  
         [0008]     U.S. Pat. No. 5,527,451 to Hembree et al. discloses a faucet mounted filter utilizing a replacement filter cartridge. The replacement filter cartridge resides within a larger rotatable housing which channels water flow either into the filter or through the diverter valve assembly. Hembree et al. also discloses a very complicated flow totalization mechanism which includes porting water to a turbine driven mechanism prior to filtering thereof.  
         [0009]     U.S. Pat. No. 6,571,960 B2 to Williamson et al. discloses a faucet-mounted water filtration device whose filter housing includes a valve therein and whose filter housing extends longitudinally rearwardly from the point of attachment to the faucet. The filters in Williamson et al. are replaceable filter cartridges.  
         [0010]     U.S. Pat. No. 6,284,129 B1 to Giordano et al. discloses a rotating magnetized impeller actuating a reed switch.  
         [0011]     U.S. Pat. No. 5,993,648 to Hunter et al. discloses a water filtration device which includes a fountain. Further, the &#39;648 patent discloses a water filtration device having an internal flow configuration such that the water may be made to flow from one of a first outlet or a second outlet by selective actuation of a gate valve along a track. The filter used in the &#39;648 patent is a replaceable filter. See, the &#39;648 patent, column 2, lines 38-40. The gate valve is spring biased which normally positions the gate valve for selective discharge from the first outlet. Water leaving the second outlet is discharged in a substantially upward direction with some left side vectoring, e.g., discharging leftward at an angle deviating 10 to 60 degrees from vertical. See the &#39;648 patent, column3, lines 18-30.  
         [0012]     In each of the foregoing disclosures, the devices disclosed therein are designed for disassembly of some sort as a matter of maintenance of the filtration device. This requires labor and attendant time. Complex flow totalization mechanisms such as the one disclosed in Hembree et al. &#39;451 present maintenance problems. The need to change the filter and/or the filter housing and/or the diverter valve all require labor and attendant time.  
         [0013]     In each of the foregoing disclosures, the devices disclosed therein are designed for disassembly of some sort as a matter of maintenance of the filtration device. Filtration devices customarily employ replaceable filter cartridges of some type. These arrangements require either a coupling arrangement for attaching and detaching a replacement filter cartridge or a large chamber to entirely enclose the replacement filter cartridge. Both approaches require additional components and materials that add to the manufactured cost and complexity of the device. Furthermore, each of the foregoing disclosures, by requiring the replacement of the filter element, cause great inconvenience to the user by having him search for and procure replacement filter elements at considerable cost. This arrangement, while lucrative for the manufacturer, is a well documented nuisance for the consumer. In addition, most of the devices in the related art, owing to their need for easy access and maintenance are relatively large and obtrusive partially blocking the sink basin. Finally, the devices noted above and most others despite the availability of high capacity filter media are not designed for long life so as to maximize the frequency with which users must purchase replacement filter elements.  
         [0014]     It is therefore desirable to have a small faucet-mounted water filtration device which is a single-use, long-life water filtration device which includes an indicator of filter performance. By single use it is meant that it is discarded when its performance indicator reveals that the efficacy of the filter has been diminished. It is also desirable to have the filter housing of the water filtration device mounted behind the connection to the faucet to enable full access to the sink basin beneath the faucet.  
         [0015]     Water pressure in homes, commercial establishments, and public buildings varies greatly. The variation in pressure is a problem for drinking fountains where the user drinks water directly from the source without the use of a vessel such as a cup or a glass. If the pressure in the water source is too high then the water is expelled with a velocity, trajectory and in an amount that is too large resulting in spillage on the user&#39;s clothing, face or floor. Variations in pressure can occur because of city water pressures which are not controlled properly. In residential well water systems variations in pressure can occur due to system operation back on the well pump curve due to low flow usage. Further pressure problems may be caused by water pressure regulators which are improperly set or need repair. It is desirable, therefore, to provide a water filtration device which expels filtered water from a fountain head in a usable trajectory and amount. It is desirable to control water pressure within a water filtration device such that it expels filtered water from a fountain head in a usable trajectory and amount. It is further desirable to adjust the flow of water from a fountain head in a usable trajectory in three axial directions.  
       SUMMARY OF THE INVENTION  
       [0016]     A single-use faucet-mounted water filtration device is provided. The device is of uni-body construction and has no removable or replaceable parts yet provides long life operation. This arrangement makes the device more convenient to use compared with other devices that require frequent replacement of filter cartridges. The device is constructed with a minimum of components making it relatively small in size and less costly to manufacture. While compact, the device is able to hold enough filter media to allow for long life operation. The life of the water filtration device is dependent upon the type of filter media used, sizing and geometry of the filter media, and the sizing and geometry of water flow paths. For instance, water filtration devices having a useful life of 300 gallons or more can be made utilizing the teachings of the instant invention. Water filtration devices having useful lives smaller than 300 gallons may also be made utilizing the teachings of the instant invention. Performance indications as a function of integrated flow are indicated by a light emitting diode.  
         [0017]     The main housing of the devices resides beneath the faucet neck and rearward of the water discharge point thus not obstructing the sink basin. A single-use device is provided for use in a kitchen sink and a device is provided for use in a bathroom sink. Unlike devices in the related art the bathroom embodiment of the single-use faucet filter is scaled to the small size of bathroom sinks and therefore practical for use in bathrooms. The bathroom filter device allows residential users to have the benefit of filtered water in close proximity to the bedroom avoiding the inconvenience of going to a kitchen sink for water during the night. In addition, because the bathroom device is small and disposable it may be taken with a traveler and installed in a hotel or motel room. Further, as travelers readily discern the differences between water and its tastes from one place to another it is highly desirable that the water filter be portable.  
         [0018]     The invention includes a front housing connectable to a water faucet and a filter housing having an inlet and an outlet. An end cap of the filter housing completes the filter housing. The front housing is non-removably affixed to the filter housing and the water filter is non-removably contained within the water filter housing. The water filter housing includes a chamber in communication with the water filter. The filter is preferably activated carbon and includes a filter pre-wrap. Other filter media may be used. The outlet resides in the chamber. Alternatively, a second outlet may also reside in the chamber in the embodiment of the bathroom filter.  
         [0019]     The single use water filtration device is small. The embodiment designed for bathroom use has a filter diameter less than or equal to 1.6 inches. The embodiment designed for kitchen use has a filter diameter less than or equal to 2.2 inches. The water filtration devices disclosed herein, namely the bathroom and kitchen embodiments, reside substantially rearwardly with respect to the water faucet. Other diameters and sizes of the water filtration devices disclosed herein may be made using the teachings hereof.  
         [0020]     The filter includes ends thereof each secured to an end cap. The end caps have peripheral seal portions which seal against the interior of the filter housing.  
         [0021]     A housing end cap is ultrasonically welded to the filter housing. Other welding methods such as microwave, radio frequency (RF), heat and induction welding may be employed to weld various portions of the water filtration devices disclosed herein together.  
         [0022]     The second outlet includes a valve seat and a valve interposed in the filter housing being operable against the valve seat of the second outlet for controlling the flow out of the second outlet. The valve includes a plunger having a foot and an elastomeric ball valve or boot residing over the foot. The foot of the plunger and the elastomeric ball valve reside within the housing. A handle is pivotally connected to the end cap of the filter housing and engages the plunger such that when the plunger is depressed the elastomeric ball valve moves inwardly toward the center of the housing and away from the seat of the second outlet. A fountain head is rotatably secured in the plunger and lever for communication with a passageway in the plunger.  
         [0023]     A spring is interposed between the plunger and the filter housing urging the elastomeric ball valve against the valve seat of the second outlet.  
         [0024]     A front housing having first and second passageways is non-removably affixed to the filter housing. The front housing includes a directional valve residing within the front housing and movable therein for directing water into the filter for filtering or through the front housing for direct use of the unfiltered water. The filter housing includes three protrusions which interengage corresponding apertures in the front housing. The front housing also includes a continuous periphery welded to the filter housing by one of the aforementioned methods. The filter housing includes a recess whose shape is the reciprocal of the continuous periphery of the front housing and the continuous periphery of the front housing fits snugly within the recess in the filter housing. The end cap of the filter housing is welded to the filter housing. Three parts or pieces, the filter housing, the front housing and the end cap of the filter housing are welded together to provide a unibody or integral construction.  
         [0025]     A gate having a magnet affixed therein resides in the chamber and swings between a first position and a second position. Spacers extending from the end cap serve to ensure that the gate remains in alignment with respect to the earth. These spacers also serve to ensure that the filter subassembly remains in proper position. The first end cap of the filter includes a first hinge member and the gate includes a second hinge member which coacts with the first hinge member to enable the gate to swing between first and second positions. A gate position sensor resides in a dry portion of the end cap of the water filter housing and is actuated when the gate swings to the second position and the magnet is in proximity to the sensor.  
         [0026]     An electronic package and a light emitting diode reside in the dry portion of the end cap of the water filter housing. The electronic package outputs a signal to the light emitting diode which indicates the performance of the water filtration device. The electronic package outputs three discrete signals to the light emitting diode to indicate three performance levels of the filter.  
         [0027]     A filter performance indicator for use in a water filter which includes a gate having a first magnet affixed thereto and a filter boundary having hinges thereon forming a pivot thereon and a second magnet affixed thereto is also disclosed herein. The gate is pivotally affixed to the hinges and is movable in an arc between a first position when no flow impinges upon the gate and the first and second magnets are coupled together and a second position when flow does impinge upon the gate and the first and second magnets are not coupled together. A filter housing includes a sensor therein for sensing the presence of the gate and the first magnet when the gate is in the second position. The filter performance indicator accurately distinguishes between flow and no flow conditions. The gate includes a conically disposed structure extending from the rear side or end thereof which coacts with a cylindrically extending passageway which extends from the filter boundary.  
         [0028]     A method of making a water filtration device is also disclosed and comprises the steps of: attaching end caps to the filter; inserting the filter within a filter housing; aligning the filter within the filter housing; inserting a portion of a gate into corresponding receptacles on one end of one of the end caps previously affixed to the filter; inserting a sensor and electronic package into an open end of a filter housing end cap; affixing the filter housing end cap to the filter housing forming a chamber between a closed end of the filter housing end cap and the one end of one of the end caps; and, affixing a front housing to the filter housing. The step of attaching end caps to said filter may be performed with adhesive. And, the steps of affixing the end cap of the filter housing, affixing the filter housing end cap to the filter housing and affixing the front housing to the filter housing may be performed by an ultrasonic welding process or one of the other welding processes identified herein.  
         [0029]     Another embodiment of the bathroom water filtration device includes a filter housing and a water filter residing within the filter housing as disclosed in connection with other embodiments. A water inlet in the filter housing admits unfiltered water to the water filter. The filter housing includes a first filtered water outlet and a second filtered water outlet as disclosed in connection with other embodiments. An upwardly extending tube having a passageway therein resides within a chamber in the filter housing and is in communication with the second outlet. Preferably the tube is a thermoplastic elastomer. A valve is movable between a first position in engagement with the second filtered outlet and a second position not in engagement with the second filtered outlet. When the valve is in its second position it is in proximity to the second filtered outlet and the passageway of the tube dividing the flow of water between the first filtered water outlet and the second filtered outlet. The tube is curved in three dimensions. Other designs may use a tube that is not curved or is curved in one or two directions. The valve does not seat against the upwardly extending tube thus dividing the flow of water to the outlets. Division of the flow of water together with controlled depression of a lever which actuates the valve enables control of the water expelled from a fountain head.  
         [0030]     Preferably the valve is an elastomeric material and is spaced approximately 0.050 inches apart from the passageway of said tube when in second position. The water filter is secured to a filter end cap and the filter housing includes a filter housing end cap. The filter end cap and the filter housing end cap form a wet chamber having controlled dimensions. The filter end cap includes an opening from which filtered water is expelled to the wet chamber and distributed through the tube to at least the second filtered water outlet.  
         [0031]     The filter end cap includes first, second, third and fourth supports for the tube to assist in positioning it out of the way from the swinging gate and aligning the passageway of the tube in proximity to the valve. The filter end cap further includes a hinge and a flow sensing gate pivotably secured to the hinge. In first position the gate resides in proximity to the opening in the filter end cap. In the second position the gate swings rotatably away from the opening in the filter end cap.  
         [0032]     Preferably the flow sensing gate and opening in the filter end cap are axially offset to avoid the tube. As disclosed in connection with other embodiments the flow sensing gate includes a first magnet affixed thereto and the filter end cap includes a second magnet affixed thereto. The magnets may be press fit into respective housings or they may be secured by adhesive. In first position the gate and its magnet are spaced apart from the filter end cap and its magnet. In first position the magnets exhibit mutual attraction. A flow sensing gate position sensor resides exteriorly to the end cap of the water filter housing. The flow sensing gate position sensor is actuated when the flow sensing gate swings to second position and the first magnet is in proximity to the flow sensing gate position sensor. The geometry of the gate with respect to the magnet in the filter end cap and the sensor in the dry portion of the filter housing end cap produces reliable flow indication.  
         [0033]     A fountain head is in communication with the filtered water outlet and expels filtered water therefrom. The fountain head includes a first adjustably rotatable member rotatable in an arc about a first axis and a second adjustably rotatable member rotatable in an arc about a second axis. The first rotatable member has a first passageway in communication with the filtered water outlet and the second rotatable member has a second passageway in communication with the first passageway. The second passageway of the second rotatable member is in communication with the exterior of the second rotatable member for the expulsion of filtered water. The first and second axes of the first and second rotatable members are orthogonal such that the filtered water is expelled from the fountain head at an adjusted and desired trajectory. Preferably the first and second adjustably rotatable members are thermoplastic elastomers and sealingly engage each other. Further, the first adjustably rotatable member seals with respect to the plunger in which it is inserted.  
         [0034]     The valve includes a plunger having a foot and a ball valve resides over the foot. The foot of the plunger and the elastomeric ball valve resides within the housing. A spring is interposed between the plunger and the filter housing urging the elastomeric ball valve against the valve seat of the filtered water outlet. A handle or lever is pivotally affixed to the housing and engages the plunger such that when the lever and plunger are depressed against the urging of the spring the elastomeric ball valve moves away from the valve seat of the filtered water outlet expelling water from the fountain head. The pivotally affixed handle is rotatable in an arc about a third axis orthogonal to the first and second axes such that the filtered water is expelled from the fountain head at an adjusted and desired trajectory in three axial directions. Another way of expressing the trajectory of the water leaving the fountain head is in terms of a vector having magnitudes along the traditional x, y and z axes.  
         [0035]     As was mentioned above in connection with other embodiments the water filter housing includes a housing end cap affixed thereto. Preferably the housing end cap is ultrasonically welded to the water filter housing. The wet chamber is defined by the filter housing end cap, the filter end cap, and the filter housing. The filter housing end cap includes a first stop and a second stop. The filter end cap includes a first protrusion and a second protrusion. The first protrusion of the filter end cap interengages the first stop of the filter housing end cap and prevents rotation of the filter end cap and the water filter attached thereto. Preferably the water filter is secured to both of its end caps with adhesive. The second protrusion of the filter end cap interengages the second stop of the filter housing end cap preventing rotational movement of the filter end cap and the filter. As with the other embodiments described herein the water filter is non-removably contained within the water filter housing and secured to the filter end caps. A passageway in one of the filter end caps communicates water from the filter into the chamber. Preferably, the passageway through the filter end cap is off-center to facilitate the design and operation of the gate such that it does not interfere with the tube or the valve. The gate preferably includes a curved protrusion which coacts with a conical discharge which protrudes from the filter end cap. The passageway in the filter end cap passes through the conical protrusion of the filter end cap.  
         [0036]     In forming the chamber, the filter housing end cap and the filter end cap are spaced apart by the first and second spacers of the filter housing end cap. In this way the dimensions of the chamber are maintained for operation of the valve and the gate.  
         [0037]     A method of making a water filtration device includes the steps of: attaching end caps to a filter; inserting the filter within a filter housing; aligning the filter within the filter housing; inserting a hinge portion of a gate into corresponding receptacles on one end of one of the end caps previously affixed to the filter; inserting a portion of a tube into an aperture within the filter housing forming a first outlet; aligning the tube with respect to one of the end caps previously affixed to the filter; affixing the filter housing end cap to the filter housing forming a chamber between a closed end of the filter housing end cap and the filter end cap; and, affixing a front housing to the filter housing. Additionally, the step of affixing the filter housing end cap to the filter housing includes the step of interengaging stops on the end cap of the filter housing with protrusions on the filter end cap preventing rotation of the filter end cap and the filter. Additionally the method may include the steps of: inserting a plunger having a shoe in a second housing outlet; placing a boot valve over the shoe; inserting a spring between the filter housing and the plunger; and, attaching a pivotable lever to the filter housing. Still additionally the method may include the steps of: inserting a first adjustably rotatable member in the pivotable lever and the plunger; and, inserting a second adjustably rotatable member in the first adjustably rotatable member.  
         [0038]     It is an object of the present invention to provide a water filtration device which is disposable and provides an indication as to when the filter should be disposed.

       [0179]     A better understanding of the drawings will be had when reference is made to the Description of the Invention and Claims which follow hereinbelow.  
       DESCRIPTION OF THE INVENTION  
       [0180]     Referring to  FIG. 1 , an exploded assembly view of a first embodiment of the water filtration device  100 , the various components of the single-use faucet mounted water filter are shown. Filter  113  is illustrated having a longitudinal bore  129  therethrough. Filter  113  is illustrated without a filter pre-wrap in this view but such a pre-wrap  495  is specifically within the scope of this invention and is illustrated in  FIGS. 4G and 4H . The filter is preferably a carbon block but may be a fiber bundle or granular activated carbon. Further, the carbon block may include bacteriastic materials, ion exchange resins and zeolites to assist in its filtration activity. End caps  114  and  115  are affixed to said filter with a hot melt adhesive applied to the entire mating surfaces of end caps  114  and  115  including but not limited to the dowel portions thereof such as dowel  130 A on right end cap  130 . Once filter  113  is affixed to end caps of filter  114 ,  115 , the subassembly is inserted into the filter housing  101 . End caps  114 ,  115  include peripheral seal portions which seal annulus  301 . See  FIG. 3  for example. O-rings  375 ,  376  ensure that water entering annulus  301  flow through filter  113  and does not bypass the end caps  114 ,  115  and migrate into chamber  350 . See,  FIG. 3D . To ensure that the subassembly is properly oriented, gate hinges  132 ,  132 A must be aligned in relation to a mark  160  on the filter housing as the subassembly is inserted into the filter housing  101 . Gate hinges  132 ,  132 A are properly positioned when their axis is parallel to the earth or parallel to a tangent of the earth&#39;s surface.  
         [0181]     Referring to  FIG. 5F , the left side view (open end view) of the filter housing  101  of the first embodiment of the water filtration device, the concave right side wall  508  of the filter housing  101  is illustrated along with molded ribs  515 . In this the first embodiment the diameter of the filter housing  101  is approximately 1.6 inches and the length of the filter housing as viewed, for example, in  FIGS. 5 and 5 A, is approximately 4.2 inches. Other dimensions may be utilized in the construction of water filtration devices as taught herein without departing from the spirit and scope of the invention. When the filter subassembly is inserted into the filter housing the right end cap abuts ribs  515 .  
         [0182]     Gate  118  is rotatably affixed to gate hinges  132 ,  132 A by inserting prongs or knobs  133 ,  133 A in the hinges. Knobs or prongs  133 ,  133 A are snap-fit into apertures in the hinges  132 ,  132 A enabling rotation of the gate  118  when water pushes against it as it exits the filter. As will be explained in more detail hereinafter, gate  118  swings (rotates) in a clockwise direction about its axis of rotation (see  FIGS. 3B and 3C ) upon the application of pressure caused by water flow through the filter  113  and the longitudinal bore  129  therein.  
         [0183]     Referring to  FIGS. 1 and 3 , gate  118  includes a magnet  117  which is press fit into a recess  134  in the gate and hermetically sealed with either hot melt adhesive or potting compound.  FIG. 3  is a cross-sectional view  300  of the first embodiment of the water filtration device taken along the lines  3 - 3  of  FIG. 2 . Presence or absence of magnet  117  is sensed by reed switch (reed relay)  135 . Housing end cap  102  includes spacers  142  and  143 . See  FIG. 8A , a perspective view of the end cap to best view the spacer  142  which is not well illustrated in the exploded assembly view of  FIG. 1 . Spacers  142 ,  143  assist in correctly spacing the housing end cap  102  with respect to the left end cap  114  of the filter. Once housing end cap  102  is inserted into the filter housing  101 , spacers  142 ,  143  ensure that the filter subassembly comprising the filter  113 , left end cap  114  and right end cap  115  does not migrate leftwardly (See  FIG. 3 ) too far and remains in proximity to the mold ribs  515  of the interior of the housing. Housing end cap  102  includes a tapered portion  190  for insertion into the filter housing  101 . A chamber is formed between the end cap  114  and the closed end  803 A of the housing end cap  102 . See,  FIG. 3 . Water is expelled from passageway  141  in the left end cap  114  of the filter housing and exerts a force against gate  118  causing it to rotate in a clockwise direction. As gate  118  rotates in the clockwise direction the magnet  117  is urged toward the reed switch  135  (reed relay) causing it to effectively close which starts the electronic timer within electronic package  112  to continuously measure the time when the magnet  117  is in proximity to the switch. The electronic package (electric circuit or integrated circuit) measures the cumulative time of flow through the filter and outputs signals to the light emitting diode (LED) indicating filter performance. The LED indicates three colors representative of cumulative filter usage one of which indicates that the water filtration device should be discarded. The electric circuit outputs three discrete signals to the light emitting diode.  
         [0184]     The electronic package is secured in a dry well  170  which in turn is secured and closed by end plate  116 . After the housing end cap  102  is installed it is welded to the filter housing  101 . The end plate  116  is glued or ultrasonically welded to the housing end cap  102 . That is, the housing end cap  102  is welded to the filter housing and the end plate  116  is welded or glued to the housing end cap  102 . Reference numeral  139  represents the raised portions of the end plate  116  which are ultrasonically welded or glued to the housing end cap  102 .  
         [0185]     Referring to  FIG. 3  again, reference numerals  302 ,  303 ,  130 ,  131  signify peripheral edges or portions of the end caps  114 ,  115  of the filter which slidingly engage and seal against the interior walls of the filter housing  101 . Referring to  FIG. 3D , elastomeric seal  375  acts as an additional optional seal which resides between peripheral edge portions  302  and  131  and elastomeric seal  376  acts as an additional optional seal which resides between peripheral edge portions  303  and  130 .  
         [0186]     Still referring to  FIG. 1 , aperture  137  permits light emitting diode  136  which stems from the electronic package  112  to pass therethrough. A small amount of potting compound may be used around the light emitting diode to seal any space between the diode and the aperture  137  when the light emitting diode is installed in place. The electronic package  112  and the substrate upon which the electronics are mounted are housed in a dry space in the housing end cap  102 .  
         [0187]     Referring to  FIGS. 1 and 5 , the filter housing  101  including its inlet  125 , filtered outlet  107 A, and filtered outlet  180  are illustrated. Filtered outlet  107 A always expels filtered water whenever water enters the filter housing inlet  125 . See,  FIG. 4H . Inlet  125  is generally cylindrically shaped and includes a recess  126  for receiving an O-ring seal  502  and a passageway  505  for conducting unfiltered water to the interior of the filter housing so that it can be filtered by filter  113 .

         [0233]     To assemble the water filtration devices, insert the aerator into the through spout and then insert the through spout and ultrasonically weld the aerator/spout assembly to the front housing. Place the threaded collar into the seat on top of the front housing and press the lock collar through the threaded collar and seat the lock collar into the housing. Clamp and ultrasonically weld the lock collar to the front housing.  
         [0234]     Insert the filtered spout into the filter housing and clamp and weld it to the filter housing. Insert the front housing into position with respect to the filter housing and then clamp and ultrasonically weld it to the filter housing.  
         [0235]     A prefilter may be wrapped around the filter and sealed using the hot seal method. Next, the left and right end caps with adhesive applied to the contact surfaces thereof are inserted in the filter. Uniform pressure is applied to the left and right filter end caps  114 ,  115 ,  1514 ,  1515  to spread the adhesive and allow it to set. Approximate time for applying pressure is 2-5 seconds. The magnet is installed into the gate under the pressure of a person&#39;s finger or a tool such as pliers or the equivalent then hermetically sealed in place.  
         [0236]     Next, the gate  118 ,  1518  is snapped into the hinges with the magnet facing outwardly. Indicia on the left end cap of the filter subassembly is aligned with a mark or other indicia on the filter housing and the filter subassembly is inserted into the filter housing. Indicia on the housing end cap  102 ,  1502  is aligned with indicia on the filter housing and inserted therein. Once the housing end cap is in place it is clamped and ultrasonically welded to the filter housing non-removably retaining the filter within the filter housing.  
         [0237]     The lever is installed by snapping it into place in the valve cavity. To install the end of life electronic package, the light emitting diode is inserted into and through the aperture  137 . Optionally, adhesive may be used when installing the diode in the aperture  137  to secure it into position and to ensure that the diode is hermetically sealed. The electronic package is installed into the reservoir in the open end of the housing end cap with the glass reed switch facing inwardly. End plate  116 ,  1516  is next snap-fit into place to hermetically seal the electronic package. Optionally, adhesive may be used around the perimeter of the end plate to ensure a hermetic seal. Or, the end plates may be welded to the housing end caps.  
         [0238]     The materials which are ultrasonically welded should be amenable to welding such as ABS or other plastics.  
         [0239]      FIG. 1A  is an exploded assembly view  100 A of a third embodiment of the water filtration device with a different left end cap  114 A and a second magnet  114 B employed. Gate  118 A is employed in the third embodiment and can be viewed in cross-section in  FIGS. 3E, 3F , and  3 G. These figures illustrate a conical protrusion  118 B extending rearwardly from gate  118 A and partially surrounded by a cylindrically extending protrusion  118 C which also emanates from the rearward side of the gate  118 A. Cylindrically shaped protrusion  118 C is larger in diameter than the cylindrically shaped protrusion or passageway  141 A which extends from end cap  114 A.  FIG. 3E  shows the relationship of the diameters of the respective cylindrically shaped extensions  118 C,  141 A.  
         [0240]      FIG. 3E  is a cross-sectional view  300 E of the third embodiment of the water filtration device with a different left end cap  118 A and a second magnet  114 B employed. Conical protrusion  118 B extends from the rearward side of the gate  118 A.  FIG. 3E  illustrates the no flow condition and the gate is in the first position. In this condition magnet  117  which resides in the gate  118 A is coupled to magnet  114 B which resides in the end cap  114 A. It is the coupling effect of the magnets which ensures that the magnet  117  does not unintentionally and improperly actuate the reed switch and indicate a flow condition.  
         [0241]     Magnets  117  and  114 B are attractive magnets and are oriented such that they attract one another. Magnet  117  is secured within the gate  118 A and magnet  114 B is secured within left end cap  114 A. A potting compound or adhesive may be used to secure the respective magnet within the gate  118 A and the left end cap  114 A. Therefore, as the magnets are attractive the gate is also attracted toward the left end cap when it is in proximity to the left end cap. As flow through the filter exits cylindrical extension  141 A with sufficient velocity and force it overcomes the magnetic coupling or attraction of the magnets  117 / 114 B and allows the gate to move in an arc to its second position. When flow is discontinued through the filter, magnets  117 / 114 B will couple when they are sufficiently proximate each to the other. The magnets help ensure that the gate will not unintentionally occupy an intermediate position between the first position and the second position. The magnets ensure that the gate resides in the first position when there is no flow through the filter.  
         [0242]     End cap  114 A is sometimes referred to herein as a filter boundary cap. It is this rearward side  118 A which experiences and reacts to the kinetic energy of the water flow emanating from cylindrical passageway  141 A of the filter end cap  114 A. Conical protrusion  118 B resides partially within cylindrical passageway  141  A of end cap  5114 A. Conical protrusion  118 B is bounded generally by a cylindrically shaped in cross-section perimeter  118 C which assists and focuses the energy of the impinging water when flow is present as illustrated in  FIG. 3F .  
         [0243]      FIG. 3F  is a cross-sectional view  300 F of the third embodiment of the water filtration device with a different left end cap  114 A and a second magnet  114 B  1 o employed and with the fountain lever depressed and with water flowing through the filter.

         [0273]      FIG. 22A  is an enlargement  2200 A of a portion of  FIG. 22  illustrating the valve  2208  and tube  2234 .  FIGS. 22 and 22 A depict the condition when no water is directed from the faucet into the filter housing as previously described herein above.  
         [0274]      FIG. 23A  is an end view  2300 A of the water filtration device absent the filter housing end cap  2231  with the lever  2122  and the valve  2208  not actuated but with water flowing as controlled by valve  2108  as explained above in connection with other embodiments.  FIG. 23  illustrates the flow of filtered water as denoted by the flow arrow and reference numeral  2301 . When valve  2108  admits unfiltered water into the annulus  2214  it passes through water filter  2213  where it is cleaned and contaminants and the like are removed. Filtered water in the center of passageway  2209  flows through filter end cap and the semi-conical structure denoted by reference numeral  2232  where it impinges on surface  2503  of the gate  2241 . Surface  2503  and curved surface  2242  on the back side of the gate under the force of the water cause rotation of the gate as illustrated in  FIG. 23  bringing magnet  2235  into proximity with sensor/reed switch  2277  as previously described herein. Operation of the sensor/reed switch  2277  is the same as previously described herein. Water flow  2301  proceeds into wet chamber  2298  around gate  2241  and into passageway  2237  of the tube  2234  and then down through the tube as indicated by reference numeral where it is expelled from first filtered water outlet  2236 .

In each of the immediately preceding and aforementioned drawing figures the tube  2234  is illustrated partially in cross-section at the top thereof because the tube is not linear or straight in a vertical direction.  FIGS. 23A and 23D  illustrate the arrangement of the gate  2241  and the tube when looking into the filter housing  2101 . Although the tube illustrated and preferred is rectangularly shaped in cross-section, it is specifically contemplated that other shapes may and can be used that do not have a rectangular cross-section. It is also specifically contemplated that passageway  2237  may undertake shapes other than circular in cross-section. The substantially rectangularly shaped tube in cross-section is supported as illustrated in  FIGS. 29, 29A , and  29 C by supports  2309 / 2331 ,  2301 / 2330 ,  2238 A/ 2305  and  2243 . It is specifically contemplated that other support shapes and placements may be used in conjunction with tubes having a substantially different shape.  
         [0276]      FIG. 27  is a perspective view  2700  of the tube illustrating its non-linearity in three dimensions. When reference is made to any one of  FIGS. 22, 22A ,  23 ,  23 A,  23 B,  23 C, or  23 D, the tube  2234  is viewed as curving rightwardly toward the filter housing end cap  2128 .  FIG. 27A  is a view  2700 A of the tube  2234  as viewed in  FIG. 22  and the other drawing figures just mentioned.  FIG. 27B  is a view  2700 B of the tube  2234  as viewed in  FIG. 23A .  FIG. 27C  is a view  2700 C of the tube  2234  of the tube from the other side of  FIG. 27A .  FIG. 27D  is a view  2700 D of the tube  2234  from the other side of  FIG. 27B .  FIG. 27E  is a top view  2700 E of the tube and  FIG. 27F  is the bottom view  2700 F of the tube.  
         [0277]      FIGS. 23A and 23D  illustrate that the flange  2303  of tube  2234  is press-fit in the filter housing  2101 . Tube  2234  is preferably manufactured from a thermoplastic elastomer and is capable of deformation to the extent of being press-fit into the housing.  
         [0278]      FIG. 23D  is an end view  2300 D of the water filtration device absent the filter housing end cap  2231  with the lever  2122  and the valve  2208  actuated and water flowing from both the fountain head  2181 ,  2182  (second filtered water outlet) and the first filtered water outlet  2236 .  
         [0279]      FIG. 23B  is a cross-sectional view  2300 B similar to  FIG. 23  illustrating the paths  2301 ,  2310 , and  2310 A of the filtered water with the lever  2122  and the valve  2208  actuated.  FIG. 23C  is an enlargement of a portion of  FIG. 23B .  FIGS. 23B and 23C  illustrate a flow divider as follows. Filtered water is flows along the path indicated by flow arrow  2301  around gate  2241  as water is expelled from semi-conical portion  2232  where curved surface  2242  ensures the opening of the gate  2241 . Simultaneously, lever  2122  under the influence of a person&#39;s hand depresses plunger  2206  urging valve  2208  off valve seat  2270  of filter housing  2270  permitting filtered water to be directed upwardly along a path as indicated by arrow  2310 A in  FIGS. 23B and 23C . When lever  2122  has been depressed to its maximum extent shroud or cover  2180  rests on the outside of filter housing  2101  which limits the travel of the plunger  1 o  2206  and the valve  2208  leaving a gap  2250  of approximately 0.050 inches between the top  2234 A of the tube  2234  and the bottom  2208 A of the valve  2208 . The action of the valve  2208  acts as flow divider whereby some of the filtered water flow is expelled upwardly through the second filtered water outlet as indicated in the direction of flow arrow  2310 A and some of the filtered water flow is expelled downwardly through the first filtered water outlet through tube  2234 .  
         [0280]     Variances in water pressure will determine the amount of depression of the lever  2122  and the valve  2208 . In other words when the source water pressure is high the lever and valve do not have to be depressed to their maximum extent. Where the source water pressure is low the lever  2122  and valve  2208  may be depressed more or to the maximum so as to lessen the flow down the tube and provide more flow to the fountain  2181 / 2182 .  FIG. 23C  indicates the maximum depression of the lever  2122  and the valve  2208  wherein the top  2208 B of valve  2208  is spaced apart from the valve seat  2270  a relatively large amount compared to the spacing between the bottom  2208 A of the valve  2208  and the top  2234 A of the tube  2234 .  
         [0281]     A method of making a water filtration device includes the steps of: attaching end caps to a filter; inserting the filter within a filter housing; aligning the filter within the filter housing; inserting a hinge portion of a gate into corresponding receptacles on one end of one of the end caps previously affixed to the filter; inserting a portion of a tube into an aperture within the filter housing forming a first outlet; aligning the tube with respect to the one end of one of the end caps previously affixed to the filter; affixing the filter housing end cap to the filter housing forming a chamber between a closed end of the filter housing end cap and the filter end cap; and, affixing a front housing to the filter housing. Additionally, the step of affixing the filter housing end cap to the filter housing includes the step of interengaging stops on the end cap of the filter housing with protrusions on the filter end cap preventing rotation of the filter end cap and the filter. Additionally the method may include the steps of: inserting a plunger having a shoe in a second housing outlet; placing a boot valve over the shoe; inserting a spring between the filter housing and the plunger; and, attaching a pivotable lever to the filter housing. Still additionally the method may include the steps of: inserting a first adjustably rotatable member in the pivotable lever and the plunger; and, inserting a second adjustably rotatable member in the first adjustably rotatable member.  
         [0282]     The invention has been described herein by way of example only. Those skilled in the art will readily recognize that changes and modifications may be made to the invention without departing from the spirit and scope of the appended claims which follow hereinbelow.
