CONTROL DEVICE 0F DYNAMIC OPERATION AND COLORED ILLUMINATION OF WATER FOUNTAINS IN SYNCHRQNISM WITH MUSIC Filed Nov. 17, 1964' 3 Sheets-Sheet 5 United States Patent CONTROL DEVICE OF DYNAMIC OPERATION AND COLORED ILLUMINATION OF WATER FOUNTAINS IN SYNCHRONISM WITH MUSIC Koreichi Kawamura, Yoshiko Kawamura, and Koichi Kawamura, all of 66 Jyomyoji, Kamakura, Japan Filed Nov. 17, 1964, Ser. No. 411,858 Claims. (Cl. 239--17) This invention relates to automatic control devices for water fountains, and more particularly to an automatic control device for producing performance and colored illumination of water fountains responsive to performance of music.

The principal object of the invention is to provide an automatic control device comprising keys and pedals similar to those of a piano and an organ and other cooperating instruments to produce the performance of water fountains by changing dynamic operation of water fountains through selecting suitable nozzles of water fountains in synchronism with a musical performance, varying the illumination of Water fountains in conformity with said mechanical performance thereof, and making combinations of said water fountains at will.

According to the automatic control device of the invention, an overall musical production including performance of water fountains consisting of a number of individual water fountain nozzles laid out in water fountain ponds can be conducted by controlling the dynamic operations and colored illumination of water fountains and by making suitable combinations of water fountains, thus controlled responsive to a given musical performance. Thereby a visual expression of a delicate atmosphere of a given music will be realized in a cubistic and colorful manner within water fountain ponds. Thus not only the effectiveness of the water fountain performances is increased but also the musical performance itself is made more impressive.

The automatic control device for water fountains of the invention comprises a performance mechanism similar to that of a piano or an organ consisting of multistaged keys, pedals, and control push buttons; control circuits for mechanical operation which control magnetic valves and pumps to supply water to water fountain nozzles by means of respective relays; time delaying circuits for maintaining illumination of an ejected water column until said water column disappears completely after a stop signal for the water supply to said water column is given; control circuits for illumination which are adapted to vary the coloring and brightness of said illumination; and combining means to select suitable combinations of water fountains thus controlled and to change said selected combination. Thereby locations of water columns, dynamic operations of ejected water columns and colored illuminations thereof are varied in synchronism with a given musical performance. In order to materialize the impression of a musical performance as a visual expression of water fountains in water fountain ponds, for instance to represent a symphony, various different types of water fountain nozzles will be installed to represent instruments such as c-ontrabasses and drums, or musical expressions such as the first melody, the second melody, obligato, spaces, etc. An operating board consisting of rows of keys like those of a piano, stop pedals like those of an organ and volume controlling devices is installed to control said nozzles in synchronism with a musical performance. The key board, for instance, will be divided into three rows, of which the first row represents contrabasses, the second row the first and second melodies, and the third rows obligato and others. While music is played by operating the keys and pedals of the operating board 'ice thus constituted, the impression of said musical performance is reflected in the performance of the water fountains by producing the dynamic operations and colored illumination of each water jet of the fountain and the combination thereof in synchronism with said musical performance.

Accordingly, the individual nozzles of water jets of fountains, which are located in water fountain ponds and controlled by said control circuits for mechanical operation, are so adjusted beforehand as to produce suitable dynamic water column forms and variation in colored illumination respective to sound levels, sound frequencies, intervals, and other musical elements of said musical performance.

For a better understanding of the invention reference is made to the accompanying drawings, in which FIG. 1 shows general arrangement of fountain control mechanism, electric control circuit and the fountain pond embodying the invention,

FIGS. 2-A, 2-B and 3-A, 3B are sectional views and end views respectively of two different fountain nozzle devices to be used in the invention,

FIGS. 4 to 6 are perspective views of curved nozzle elements corresponding to FIGS. 2 and 3 and a cylindrical nozzle having multiholes respectively, and

FIGS. 7-A, 7B and 7C are perspective views of dif- I ferent configurations of the fountains obtainable by the nozzles as shown in FIGS. 4 to 6 respectively.

In these drawings, the same or similar parts are shownby the same reference numeral.

Referring to FIG. 1, which illustrates a water fountain pond, a number of groups of water fountains installed in the pond, a typical illumination means, electrical control circuits, an operative means or a performance mechanism, and wiring for connecting said means, 1 is a Water fountainpond having a plurality of water fountain groups W W W which comprise a plurality of individual water fountain elements having mouth pieces such as shown in FIGS. 4, 5 and 6. In order to give a dynamic form of water column as shown in FIGS. 8-A, 8-B and 8-C, each individual Water fountain structure is constructed as shown' in FIGS. 2-A, 2-B and 3-A, 3-B and fitted with a mouth piece as illustrated in FIGS. 4 to 6. Thereby each individual water fountain will be operated in a manner to be explained later so that the impression of ,a given musical performance will be materialized in the overall dynamic operation and colored illumination of water fountains in the pond.

Referring to FIGS. 2-A, 2-B and 3-A, 3-B, which illustrate examples of individual water fountain structure embodying the invention, 6 is a water supply tube, 7 an ejection nozzle, 8 a ball joint, 9 a packing, 10 a union unit, 11 a water-guide cylinder, having air inlet openings 12, fixed to the nozzle 7 and enclosing it, 13 a hood having intake opening 13, fitted to cover the cylinder 11, and 14 a mouth piece fixed to the cylinder 11 and having a straight flattened outlet opening to form a fountain having the configuration as shown in- FIG. 7-A.

In FIGS. 4 and 5, the mouth pieces 14 having a curved narrow outlet opening 14' or 14" respectively are shown, to form a fountain having the configuration as shown in FIG. 7-B, and FIG. 6 shows a cylindrical mouth piece 14 having multiple small holes to form a fountain having the configuration as shown in FIG. 7-C.

Colored illumination lamps to light water columns ejected from individual nozzles in a group of water fountain nozzles are represented by W and for each individual water fountain nozzle a colored illuminating means consisting of light bulbs equipped with one of a group of colored filters red Re, green Gr, blue BI and yellow Ye, or a light bulb equipped with a group of colored filters in an exchangeable manner, and said colored illuminating means W are placed close to the water surface of the pond to illuminate each water fountain column in such a manner as to give a visual impression suitable to the accompanyingmusic by controlling the on-off and brightness thereof.

The operating board 2 of the water fountains is shown in the lower portion of FIG. 1. P P and P are water fountain selectingkeys for each water fountain group, and P and P are similar selecting pedals. Holding keys PH PH and PH and holding pedals PH, and PH which are located at the extreme right of each key row and each pedal row, respectively, are intended to hold the operations of water fountain groups corresponding to each key row or each pedal row. Coloring selection switches Q for each water fountains group are provided to choose coloring of colored illuminating means W which project colored light rays to illuminate the fountain water columns, and T are regulating buttons to adjust the height of ejected water columns.

On the extreme left of the operating board 2, there are provided operating buttons S S and S for relays to compose proper combinations of water fountains.

Key switches K K K in the control circuits cooperate with each key or pedal on the operating board to operate nozzles of corresponding water fountains. Relays L L L are energized by means of key switches K K K respectively. EV EV EV show terminals of solenoid valves connected to contacts a of relays L L L,,, and said solenoid valves regulate the water supply to water fountain nozzles. In

to red, green, blue and yellow light bulbs which are connected in series to said individual color relays 3Re, 3Gr, 3B1 and SYe respectively The brightness adjusting rheostat means 4 is adjustable by turning the knob 5 on the operating board 2.

In the automatic control device thus constructed, if a key or a pedal, one of P to P is operated responsive to a musical performance, that key switch which is connected to said operated key or pedal will be closed. For the purpose of explanation, suppose the key switch K is closed. By closing K the relay L is energized to close the contact a which energizes the solenoid valve EV in turn, thus water is supplied to the corresponding nozzle and ejected therefrom as a water fountain column. The contact of the relay L is also closed to energize the time delay circuit D and hence the time delay relay U is energized. Since there is a time delay circuit comprising R and C having a predetermined time constant, which is connected to the input side of the transistor V the operation of the relay L; will be maintained until the related water column completely disappears. When the contacts a and f of the relay L' are closed upon energization thereof, the holding relay L" and the coloring relay L" will be energized causing contacts g and order to adjust the height of water columns ejected from 1 said water fountain nozzles, there are provided suitable water flow control means (not shown) in said water supply tubes to, water fountain nozzles, and said water flow control means are controlled by said regulating buttons T to adjust the height of ejected water columns. To indicate operating conditions of the relays, pilot lamps PL PL PL are connected in parallel to each relay L L L Time delay circuits D D D are connected to contacts b of said relays L L L and each time delay circuit comprises a resistor R, a condenser C and a transistor V, and said resistor R and said condenser C are connected in parallel to give a predetermined time constant suitable for the desired time delay. Time delaying relays L' L' L are connected to transistors V in each said time delaying circuit, and contacts e of said time delaying relays operate holding relays L" L" L" to hold contacts groups g g g of light bulbs W for projecting colored illuminations to water fountain columns, and contacts of said time delaying relays operate coloring relays L"' L' L"' Said time constant defined by the parallel circuit consisting of a resistor R and a condenser C should be selected sufficiently long to maintain the projection of colored illuminations to water columns until said water columns fade out completely after stop signals are given to the water supply for said water columns. Said coloring relays are to provide a specific water fountain with a single specific color of the illumination of the water columns thereof when coloring "selectionrelays 3 are not energized.

The coloring selection relay 3 consists of individual color relays such as 3Re, 3Gr, 3Bl, and 3Ye, which are connected to corresponding colored light bulbs by way of contacts g of the holding relays L" L Lfl When the coloring selection relay 3 is operated by pushing coloring selection switches Q which are provided for each water fountain group and located on the operating board 2, the coloring of the illumination for all water columns of the selected water fountain groups is immediately changed into the selected color by simultaneous operation of a coloring change-over relay RS with one of said individual color relays such as 3Re, SGr, 3B1 or 3Ye.

A brightness adjusting rheostat means 4 consists of in-. dividual rheostats SRE, SGr, SBl and SYe corresponding a contact 12 to close.

There are a set of colored light bulbs consisting of Re, Gr, Bl and Ye for each group of water fountains, and one of which is selected to be the predetermined color of said group, the circuit of which can be traced from one terminal of said selected colored light bulb, through one contact of the coloring changover relay, contact b of the coloring relay L' an individual brightness ad justing rheostat corresponding to said selected color and a power source means, to the other terminal of said selected colored bulb. The circuit for each colored light bulb other than said selected one in said set can be traced from one terminal of the colored light bulb, through the other contact of the coloring change-over relay, one of the contacts g an individual color relay corresponding to the color of the light bulb, an individual brightness adjusting rheostat corresponding to the same color, and a power source means, to the other terminal of the light bulb.

In the circuit of FIG. 1, if the contact b of thecolor relay is closed, the red light bulb will project an allurninating light to light up the related water column, the brightness of which is set by adjusting rheostat SRe. Such illumination is continued even after the key switch K is opened, until the related water column is completely faded, and thereafter the circuit of the light bulb Re is opened when the relay L is deenergized.

By operating the keys and pedals of the operating board, the dynamic operation of the water columns and the illumination thereof will be varied responsive to the musical performance. To change the coloring of the illumination, while the predetermined color of the group is used, the coloring selective button Q is pressed, and then the coloring selective relay 3 and the coloring changeover relay Rs are energized simultaneously. Thereby the circuit for the predetermined color of the group by way of the contact 12 of the color relay L' is opened at the coloring switch over relay Rs and the circuit for the desired color, selected by pressing the corresponding selection button, is completed from the power source means to the light bulb. Thus the coloring of the illumination of water columns of the water fountain group concerned will be changed into the desired color simultaneously.

The adjustment of the brightness of the illumination can be done by adjusting the resistance of the rheostat 4 by turning the knob 5 located on the operating board 2. When one or more of the holding keys and pedals PH to PH are operated, the circuit of the corresponding relays among L to L will be maintained as energized by the operation of corresponding key switches among K to K which are located in the rows of operated holding keys or pedals. Such a holding of the circuit is effected by means of switches H which cooperate with the holding keys and pedals, and release of such holding circuits is effected by opening normally-closed switches I. There are holding circuit contacts C between said two kinds of switches H and I which are connected in series thereto and controlled by the relays L L L In order to actuate certain groups of water fountains without operating keys or pedals thereof while the other groups of water fountains, combination relays 8' 8' S are provided between the power source and each of relays L L L by way of suitable combinations of rectifiers SL. By pressing desired operating buttons of S S S corresponding ones of said combination relays 8' 8' S are energized and thereby corresponding desired group of water fountains will be actuated and the dynamic picture of the entire assembly of water fountains will be varied without operating any key or pedal.

For instance, if combination relays 8' or 5' is energized by pressing corresponding push-buttons while the group of water fountains corresponding to the key switch K is operating, then the circuit of the relay L is ener gized via selenium rectifiers SL or SL' in the same manner as if the key switch K were closed. Thus a dual water-columns operation or a multi-columns operation of v the water fountains will be effected.

The mechanism of the water fountains of the invention is as described in the foregoing, and by actuating operating means similar to those of a piano or an organ, such as rows of keys and pedals, a wide variety of dynamic operation and colored illumination of water fountains placed in water fountain ponds can be obtained, and said variation can be done in synchronism with a musical performance. Besides, the colored illumination of water fountains is so made as to maintain said colored illumination until related water columns are completely faded. Thereby the productive effects of the operation of water fountains is improved substantially.
