Illuminated pool fountain system

An illuminated pool fountain system (10) for projecting a spray of water in a pool while illuminating the water and the system, the projecting and illuminating being done in a safe convenient and economical manner, the system comprising, in combination:

• a pool (14) containing a quantity of water (16), the water having a waterline (18), the pool having a water outlet (20) beneath the waterline ejecting water into the pool, the outlet having female screw threads (22);
• a vertical pipe (26) having an upper end (28) above the waterline and a lower end (30) below the waterline, the lower end formed with a 90 degree bend terminating in a lower free end, a horizontal connector pipe (32) coupling the lower free end of the vertical pipe and the water outlet, a threaded collar (34) adjacent to the water outlet and rotatable around the connector pipe for tightening and loosening the connector pipe with respect to the water outlet;
• a pressure adjusting assembly (38) including a rotatable sleeve (40) in a cylindrical configuration co-axially mounted on the horizontal pipe, the rotatable sleeve having a rectangular exterior aperture (42), a circular interior aperture (44) in the horizontal pipe, the rotatable sleeve being rotatable between an open first orientation with the interior and exterior apertures aligned and a closed second orientation with the interior and exterior apertures un-aligned for thereby varying the pressure of the water flowing there through as a function of the rotational orientation of the rotatable sleeve with respect to the horizontal pipe;
• a T-coupler (48) having a horizontal first leg (50) and an axially aligned horizontal second leg (52) and a downward extending vertical third leg (54), male screw threads on the vertical third leg, a joining component (56) at the upper end of the vertical pipe with female screw threads for removably receiving the T-coupler;
• a transparent plastic first sleeve (60) having an interior end attached to the first leg of the T-coupler, the first sleeve having a second end with a first cap, a transparent plastic second sleeve (58) having an interior end attached to the second leg of the T-coupler, the second sleeve having a second end with a second cap;
• an illumination assembly including an inner cylinder (64) of a translucent cellulose material within the second sleeve, the inner cylinder having a closed end adjacent to the second cap, the inner cylinder having an open end within the T-coupler, the illumination assembly also including a power cylinder (66) with a first end adjacent to the first cap, the first end of the power cylinder having a button (76) extending through the first cap, the power cylinder having a second end within the T-coupler with a gasket (68) there around hydraulically sealing the first sleeve from the second sleeve and the T-coupler, a plurality of light emitting diodes (70) coupled to the second end of the power cylinder extending into the T-coupler, a plurality of batteries (72) within the power cylinder, electronic logic (74) within the first sleeve operative in response to depressing the button for activating and inactivating the light emitting diodes, the depressing of the button adapted to optionally operate the light emitting diodes in a continuous and discontinuous modes;
• and
• a spray assembly including apertures (78) in the second sleeve, the apertures facing upwardly and outwardly whereby water is adapted to move through the outlet, then through the pressure adjusting assembly, then through the T-coupler, then through the second sleeve exterior of the translucent sleeve, and then exiting through the apertures whereby the exiting water creates an illuminated fountain-like appearance while the light emitting diodes illuminate the exiting water and the first and second sleeves.
