   BACKGROUND OF THE INVENTION 
   1. Field of Invention 
   A modified shower head provides a timepiece imbedded within a shower head insert allowing a person showering to keep track of time and also to monitor water usage. It also provides the person showering with a timing mechanism to determine the length of time for use of hair products, tints, dyes and treatments without having to reference an outside timepiece. The insert comprises a timepiece within an encased water-proof enclosure. 
   2. Description of Prior Art 
   The following United States patents were discovered and are disclosed within this application for utility patent. All relate to mechanisms which incorporate timed apparatus within a shower delivery system. 
   Two patents describe devices that control the flow of water with a timed shutoff means. In U.S. Pat. No. 2,545,928 to Martin, the automatic water shutoff device has a timer which closes a mechanical valve after a set period of time has expired. It does not tell time, but could, since it embodies a clock face. A similar device is disclosed in U.S. Pat. No. 4,345,621 to Dunckhorst, except it is specifically adapted to a shower head having a rotary dial to set the time of water flow. It does not tell time. 
   Most closely similar is a combination timepiece shower head, U.S. Pat. No. 4,944,049 to Leonard, with the first several claims dealing with the aspects of the mechanical shower head with a clock within a housing. The last eight claims deal with the shower apparatus having an electronic clock, a digital clock, a display of real time in digital form, a real time/elapsed time combination display, a battery operation, and a switching means for the clock. It is basically a replacement shower head replacing the conventional shower head without a timepiece. It does not disclose the housing as related to the clock, except for a cursory mention in column 3 lines 51-68, with any specific detail, other than to state that “the clock display . . . is mounted in housing . . . and is completely sealed from water contamination.”, lines 62-64. 
   A simple hourglass timer which attaches to a shower wall is disclosed in U.S. Pat. No. 5,260,918. Several other patents of this nature were also discovered which provide a simple waterproof clock for use in the shower or bath. However, none of them provide any reference which would indicate same or similar elements as would be found in the present device. 
   SUMMARY OF THE INVENTION 
   Shower head have been in use for years. Typically, these shower head comprise a shower head cone with an insert for adjusting the water flow and spray patterns of the shower head. While these devices are suitable for their intended purposes, they are not suitable for the placement of an interchangeable plug with a functional clock face and a selection of decorative backgrounds. It would be desirable if the ordinary shower head would include an interchangeable functional clock and a decorative background to blend with the colors and decor of the bathroom and shower or to suit the chosen taste of the user. 
   In this regard, the present timepiece shower head replaces a traditional insert of a shower head with a waterproof timepiece having a selected background, serving a function of still adjusting the flow and spray pattern of the shower head, but also providing a timepiece for the user to tell time, determine the passage of time and also to set an alarm of an alert when a given amount of time has elapsed to conserve water and to prevent too much time being spent in the shower. 
   The primary objective of the invention is to provide a shower head having an interchangeable plug insert including a clock and a background scene or icon. A second objective is to provide the shower head with the ability to inform a user of the current time, preventing people from being late, from using too much water or for use with timed hair and hygiene treatments. A third objective is to provide the insert with a different aesthetic appearance to suit the taste of the user. A fourth objective is to provide the plug insert as a means of conserving water usage or to allot the amount of time each user spends where a large number of occupants reside within a single household. A fifth advantage lies with a parents ability to train a child to take an appropriate amount of time in the shower. Other advantages may be realized may be obvious to a user which would be obvious to those users within the scope of this improved shower head insert.

   DESCRIPTION OF THE PREFERRED EMBODIMENT 
   An improvement to shower head providing an interchangeable waterproof timepiece member  10  to replace a shower cone regulator insert  110  within a shower head cone  100  pivotally and rotatably attached to a shower pipe stem  120  emanating from a wall  130  within a shower or bath,  FIGS. 1-2 , the improvement, shown in  FIGS. 4-5 , comprising the interchangeable waterproof timepiece member  10  defining a shower piece insert  20  having an externally threaded nipple  23  on a rear surface  22  inserted into an internally threaded female receiver  102  within the shower head cone  100 , the shower piece insert  20  further defining an outer perimeter elevation  24  having an O-ring groove  25  for the insertion of an O-ring  30  and a front surface  26  defining an externally threaded rim  27  and an inner cavity  28 , the inner cavity  28  containing a sealed timepiece  40  with an ornamental background  44 , a rubber seal washer  60  maintaining a waterproof compression seal between the sealed timepiece  40  and the inner cavity  28  and an internally threaded outer seal ring  70  having an open timepiece display orifice  72 , retaining an outer portion  42  of the sealed timepiece  40  within the inner cavity  28 . The sealed timepiece  40  further comprises a clock face  41 , either digital or analog, an inner chamber  43  wherein a low voltage power supply  45  operates a clockwork assembly  46  and a waterproof seal cap  48  on a rear portion  47  of the sealed timepiece  40  forming a watertight seal to the sealed timepiece  40 . 
   The externally threaded nipple  23  of the shower piece insert  20 , being easily removed from the internally threaded female receiver  102  of the shower cone  100 , allows for the removal of the interchangeable waterproof timepiece member  10  to gain access to and change the sealed timepiece  40  or open the waterproof seal cap  48  to gain access to the clockwork assembly  46  to change the time or the change the low voltage power supply  45  when spent. In other embodiments, the externally threaded nipple  23  may be replaced by another form or generic connecting means that would allow the shower piece insert to be connected within the shower cone as a substitute for the existing cone regulator insert  110 . However, the other structures would remain consistent. 
   The interchangeable waterproof timepiece member  10  may be made from many selected materials, but it would be best if the shower piece insert  20  was made of a similar material or a durable metal or plastic as the shower cone regulator insert  110  being replaced, rigid and non-deformable, especially since the interchangeable waterproof timepiece member  10  would be under pressure from the water. The O-ring  30  would preferably be a flexible rubber, compressible to form a tight seal between the shower piece insert  20  and the shower head cone  100  to allow a controlled flow similar to the shower cone regulator insert  110  being replace to maintain the function of the original shower head. The rubber seal washer  60  should also tightly conform to the sealed timepiece  40  and be deformable allowing the sealed timepiece  40  to be compressed within the inner cavity  28  and retained without movement once the internally threaded outer seal ring  70  is applied to the externally threaded rim  27  of the shower piece insert  20 . The internally threaded outer seal ring  70  may be made of metal, plastic or other non-deformable rigid material with a finish to complement the shower head cone  100  and the sealed timepiece  40  framed within the timepiece display orifice  72 . 
   The sealed timepiece  40  may also provide an alarm which may be set for a chosen length of time, a mode selection button to select between real time and a timed chronometer, and a switch to activate and deactivate the alarm setting and to set the clock for use in the user&#39;s time zone location, if it would be more convenient to leave the sealed timepiece in the inner cavity to change the timepiece settings. The alarm may be provided by a buzz or a small audio loop which would be programmed into a timepiece sound module, which may be related to the ornamental background  44 . By example, if the ornamental background  44  were a sports insignia, the alarm may be provided as a sound loop for that particular team song. As another example, although not suggesting use without the appropriate license, if a cartoon character were provided in the ornamental background  44 , a song associated with that cartoon character might be appropriate. Although not necessarily shown in the drawings, these timepiece features already exist in the prior art and are not within themselves novel, but may be incorporated within the sealed timepiece  40 . 
   The sealed timepiece  40  may also include as an accessory, not shown but contemplated within the scope of this shower head insert where new technologies may apply, a video screen or a small radio. It is also contemplated that a recharging means, not shown, may also be included using the water flow associated with the shower head, to recharge the internal low voltage power supply  45 , with a type of water wheel generation system. 
   While the improvement has been particularly shown and described with reference to a preferred embodiment thereof, it will be understood by those skilled in the art that changes in form and detail may be made therein without departing from the spirit and scope of the disclosed interchangeable waterproof timepiece member  10 . Further, the foregoing disclosure is considered illustrative only of the principles of a shower piece insert  20  and may be modified to suit other shower heads of any shape or form. The shower head insert  20  may be presented in a form which would replace the cone regulator insert  110  in any shower head and thus define any connecting structures or connecting means  23  that would allow for the improvement to be substituted for the currently manufactured shower cone insert  100 . Further, since numerous modifications and changes will occur with those skilled in the art, if is not the intent of this disclosure to limit the improvement to the exact construction and operation shown a described. Thus and accordingly, all suitable modifications and improvements resorted to may be considered within the scope of this improvement to any conventional shower head.
