signor to Dancing Waters, Inc., New York, N.Y., a corporation of New York Filed Jan. 8, 1957, Ser. No. 633,043 Claims priority, application Germany Nov. 9, 1956 16 Claims. (Cl. 239--17) This invention relates to a novel and improved nozzle arrangement for water displays of the type in which fountain units are arranged in groups and are regulated rhythmically or selectively to produce visual effects. The nozzle assembly of this application is intended, for example, to be used as a part of the fountain installation shown and described in my co-pending United States patent application, Serial No. 377,596, now Patent No. 2,787,495, filed Aug. 31, 1953 and is shown therein as part of the complete fountain. This application is a continuation-in-part of the aforementioned patent appli cation.

Water displays of the type mentioned above are referred to as dancing fountains. The invention herein relates particularly to a plurality of nozzles for such fountains, which nozzles are arranged in groups and rotatably mounted about a substantially vertical axis.

It is customary in dancing fountains to vary the height of the water streams rhythmically where desired, as for example, in synchronization with music or musical effects. The object of the present invention is to provide a nozzle arrangement which will produce a spray arrangement forming an upstanding water figure, which figure may be readily and radically changed or varied in configuration as well as in height.

A novel characteristic of the invention is the selective adjustability of the water flow supplying the particular groups of nozzles. The water flow to one group of nozzles may be controlled or adjusted independently of that to the other groups of nozzles. in accordance with the invention, this control may be effected in two ways: First, several main pipe conduits are provided from which branch conduits lead to various groups of nozzles in one assembly, and each main pipe conduit may be independently controlled or adjusted. In the second way, the areas of the water inlet openings in the main pipe which lead to the nozzles are adjustable by means of sleeves which are axially movable in the main pipe. Additional objects and advantages of the invention will become apparent during the course of the following specification when taken in connection with the accompanying drawings in which:

Fig. 1 is a vertical section taken centrally through a nozzle assembly made in accordance with the invention, substantially along the lines 1-1 of Fig. 2;

Fig. 2 is a top plan view of the nozzle assembly shown in Fig. 1 with portions of the conduits or pipes broken away for convenience of illustration;

Fig. 3 is a central vertical section corresponding to Fig. 1 but through a modified type of nozzle arrangement also made in accordance with the invention; and

Fig. 4 is a plan view of the nozzle arrangement shown in Fig. 3.

The nozzle assembly of the invention broadly comprises an arrangement of nozzles in which a plurality of vertically-disposed nozzles are arranged in a circle and are mounted to revolve about a vertical pipe, option-ally in combination with fixed nozzles or groups of fixed nozzles.

Figs. 1 and 2 illustrate a nozzle unit, one or more of which may be incorporated into a fountain display. The

tates Patent unit shown in Figs. 1 and 2 comprises four separate groups of nozzles, two of which are movable and two of which are fixed. The nozzles of each group are disposed on the circumference of a geometric pattern, the shapes of the different groups being similar and of different sizes. One of the nozzle groups consists of nozzles 2' which are upstanding from the top of a hollow housing 2, and are arranged in a circular row on said housing. While the number of such nozzles 2' is optional and may be selected to suit the particular display, eight of said nozzles 2' are shown in Fig. 2 in their circular arrangement. The hollow housing 2 is fixedly mounted at the top of a rigid support pipe 1 which is vertically or substantially vertically disposed, and acts as a cover to close off the top of said pipe 1. The housing 2 is fed with water under pressure by a conduit 3 which extends through the wall of pipe 1 and then extends upwardly through the interior of pipe 1 communicating with the bottom of the hollow housing 2 as shown in Fig. 1.

The second nozzle group consists of a single nozzle 4 which is mounted at the top of the housing 2 and is disposed vertically at the center of the circular row of nozzles 2. The nozzle 4 is fed by a separate conduit 5 which also extends through the wall of pipe 1. and then extends vertically through said pipe 1 to said nozzle 4.

On the external circumference of pipe 1, a pair of vertically spaced rings 6 and 7 are rotatably mounted. Each ring 6 and 7 carries a plurality of radially-projecting pipes 6' and 7' at the ends of which respective vertically-extending nozzles 6 and 7" are mounted. In the preferred form of the invention shown in Fig. 2, the ring 6 is shown carrying four radial pipes 6 and the ring 7 is shown carrying four radial pipes 7', although the number of pipes and nozzles may be varied as required in the display. The nozzles 15" comprise the third group of nozzles and the nozzles '7" the fourth group.

Both rings 6 and 7 are hol'ow and have respective interior circular chambers 8 and 9 which communicate with the interior of pipe 1 by means of respective openings 1a and 1b in said pipe 1. The ring 6 has mounted on its lower end an annular bevel gear 10. The ring 7 has a pair of bevel gears 11 and 12 respectively mounted at its top and bottom ends. A bevel gear 13 is rotatably mounted on the pipe 1 for turning about a horizontal axis and is in mesh with the gears 10 and 111 in such a manner that the rings 6 and 7 will rotate about pipe 1 in opposite directions. The gear 12 is driven by the bevel gear 14 which is mounted on a horizontally disposed shaft 15 which extends entirely through pipe 1, as shown in Fig. 2. The shaft 15 is adapted to be driven by an external power source such as an electric motor, whereby the rings 6 and 7 with their respective nozzles 6" and 7" are whirled rapidly about the pipe 1' as an axis, in opposite directions.

The pipe 1 is connected to a main conduit 16 of the fountain display while conduit 3 is connected to a separate main conduit 17, and conduit 5 is connected to a main conduit 18. The main conduits or water lines 16, 17, and 18 of the fountain display are filled with water under pressure, which pressure may be independently adjusted in each water line or conduit, or may be shut off entirely. The conduits 16, 17 and 18 may also be connected to other nozzle arrangements of the fountain display.

In Fig. 2, a flexible, self-adjusting coupling 19 is shown, the coupling serving as a means of connection its face, which studs are off-set from the center of disk 20 and are preferably arranged circularly about said center. The studs 22 extend through respective openings in the disk 21, thereby providing a coupling between the two disks by means of which the disk 21 may be rotated by disk 20. A rubber ring 23 is disposed between the faces of disks 20 and 21, the ring 23 also having openings through which studs 22 extend. The coupling 19 allows for sufficient play during rotation of the shafts 15 and 15', so as to make exact axial alignment of shafts 15 and 15 unnecessary. This finds particular importance in connection with water displays which are of a temporary nature, and are intended to be set up and dismounted quickly and conveniently.

When the shaft 15 is driven, the groups of nozzles 6" and 7" are rotated rapidly in opposite directions to provide a novel fountain configuration. The water pressure in the main conduit 16 may be varied gradually to produce gradual or successive changes in this configuration. At the same time, the height of the water jets emerging from the nozzles 12' may be regulated by adjusting or rhythmically varying the pressure in the main conduit 17, and in a similar manner the height of the jet emitted from nozzle 4 may be similarly regulated by selective control of the water pressure in the main line or conduit 18.

The nozzle unit, as above described, is capable of producing extremely dramatic and lively water effects. In practice, a number of such units, for example six, are evenly spaced in a row extending the length of the fountain display, and are preferably operated independently of the other nozzles and nozzle arrangements in the display. That is to say, for best results, the remaining nozzles in the fountain display are turned off entirely while the nozzle units of the invention are operated. The ring of nozzles 2' produces a vertically-extending substantially cylindrical cascade of water, with a singe stream rising from its center, produced by the central nozzle 4. When the nozzles 6" and 7" are rotated and fed with water from the conduit 16, they produce jet swirls which cut through the central cascade, resulting in a rapidlymoving and form-changing swirling water effect. Visually, this effect gives the impression of leaping flames, and the dramatic effect may be heightened if coordinated with colored lighting of the water.

Figs. 3 and 4 show a modified construction'in somewhat simpler form, which, in common with the embodiment of Figs. 1 and 2, has the central upstanding fixed main nozzle 4, upper rotatable nozzles 6" mounted on ring 6. and lower rotatable nozzles 7" mounted on ring 7. The circular row of nozzles 2 are omitted inthis embodiment.

The rings 6 and 7 are driven by shaft 15 through the same type of bevel gear arrangement as was described in connection with the unit of Figs. 1 and 2.

The nozzle unit shown in Figs. 3 and 4 differs from that of Figs. 1 and 2 in that it is fed by a singe water main or conduit 24 instead of the three separate conduits of the previous embodiment. Since all of the nozzle groups are supplied with water from the same conduit 24, the regulation of the various water streams or jets is effected in a different manner.

The main conduit 24 is connected to an upstanding pipe 25 which has an outer jacket 26 spaced from the pipe 25 to provide a water chamber therebetween. The annular chamber formed between pipe 25 and jacket 26 is closed at its top and bottom ends and is divided into an upper chamber 35 and lower chamber 36 by a wall or partition 28 located between the two rings 6 and 7. The upper chamber 35 communicates with the interior of the hollow upper ring 6 through openings 37 in the wall of jacket 26. Similarly, the lower chamber 36 communicates with the lower ring 7 through jacket wall openings 38.

The pipe 25 has internal threading at its upper end into which a sleeve 29 is screwed. The nozzle 4 is mounted on an elongated pipe 31) which is externally threaded. The top wall of sleeve 29 has a central, internally-threaded opening in which the externallythreaded pipe 30 is mounted for vertically-adjusted movement.

The upstanding pipe 25 has a plurality of verticallyelongated slots or openings 33 which communicate with the lower chamber 36, so that water fed from main conduit 24 to pipe 25 will pass through said openings 33 into the lower chamber 26 and then flow through openings 38 to the lower nozzles 7". The size of the slots 33 may be regulated by a short pipe 32 of large diameter which is mounted on radial vanes or ribs 31 fixed to the bottom end of pipes 39. When the pipe 30 is turned within the sleeve 39, the extension pipe 32 is raised or lowered relative to the slots 33 thereby increasing or decreasing the lengths of said slots and consequently varying the force of the stream or jet emitted by nozzles 7".

Pipe 25 also has a plurality of elongated slots 34 communicating with the upper chamber 35 to supply water to nozzles 6" through openings 37 and ring 6. The size of these slots 34 may be adjusted by turning sleeve 29 in the threaded upper portion of pipe 25, whereby the water pressure in the nozzles 6" may be adjusted.

By this construction, the size of the streams or jets emitted by the nozzles 6" and 7" may be adjusted independently of each other and of the central nozzle 4. Rhythmic variations in the height of the jets are pro duced by varying the pressure in the main conduit 24.

While preferred embodiments of this invention have been shown and described herein, it ,is obvious that numerous additions, changes and omissions may be made in these embodiments without departing from the spirit and scope of the invention.
