Abstract
Abstract A nozzle assembly for producing an internally illuminated, coherent column of water for a fountain. The assembly is constituted by a flow tube having a water inlet and a core piece concentrically mounted within the tube by means of a laterally extending pedestal to define an annular flow passage interrupted by the pedestal. The resultant hollow column of water discharged from the mouth of the nozzle has a longitudinal slot therein whose width is determined by the geometry of the pedestal, the slot exposing the interior of the column to the atmosphere, thereby preventing the collapse of the column that otherwise would occur because of vacuum forces. The core piece has a cuplike formation and houses a light source which projects a light beam through the hollow of the water column.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
79 words
A nozzle assembly for producing a coherent column of water comprising: A. a flow tube having a water inlet, B. a core piece coaxially mounted within the tube by a laterally-extending pedestal to create a longitudinal slot in the hollow water column emitted from the mouth of the flow tube to expose the interior of the column to the atmosphere, the head of the core piece which faces said inlet being rounded to minimize the impact of water thereon.
Claim 2
Dependent Claim
79 words
A nozzle assembly for producing a coherent column of water comprising: A. a flow tube having a water inlet, B. a core piece coaxially mounted within the tube by a laterally-extending pedestal to create a longitudinal slot in the hollow water column emitted from the mouth of the flow tube to expose the interior of the column to the atmosphere, the head of the core piece which faces said inlet being rounded to minimize the impact of water thereon.
Claim 3
Dependent Claim
36 words
A nozzle assembly as set forth in claim 1, further including a light source disposed within the core piece to produce a beam of light which is directed through said hollow to illuminate the water column.
Claim 4
Dependent Claim
20 words
A nozzle assembly as set forth in claim 2, wherein said beam of light is produced by a reflector-type bulb.
Claim 5
Dependent Claim
31 words
A nozzle assembly as set forth in claim 2, wherein said light source is a bulb associated with an external dimmer to change the color of light emitted by the bulb.
Claim 6
Dependent Claim
16 words
An assembly as set forth in claim 4, wherein said bulb is of the quartz-halogen type.
Claim 7
Dependent Claim
26 words
An assembly as set forth in claim 1, wherein said head is provided with a concave depression to create a mound of water cushioning said impact.
Claim 8
Dependent Claim
37 words
A nozzle assembly as set forth in claim 1, wherein said inlet is provided with a mounting flange and a constricted pipe section leading to an enlarged cylindrical main section within which the core piece is mounted.
Claim 9
Dependent Claim
45 words
A nozzle assembly as set forth in claim 7, wherein said core piece has a generally cylindrical form and is concentrically mounted within the main section of the flow tube, the leading edge of said pedestal being sloped to minimize the impact of water thereon.
Claim 10
Dependent Claim
20 words
A nozzle assembly as set forth in claim 1, wherein said pedestal is segment-shaped and converges toward said core piece.
Claim 11
Dependent Claim
31 words
A nozzle assembly as set forth in claim 9, wherein the geometry of said pedestal produces a 45* interruption in said annular passage at the inner wall of said flow tube.
