This invention relates to ornamental colored fountains and has as its prune object the provision of a novel, and ornamental colored fountain adapted for use in parks, gardens, courtyards and the like.
Heretofore the colored illumination of ornamental fountains has been limited to the successive fading-in and fading-out of differently colored flood lights directed towards said fountain. The area solely subject to a single one of these flood lights exhibits the color of that light. The area where these lights overlap exhibits a compound color produced by the mixture of the colors of the overlapping lights. This type of colored flood lighting for fountains has been widely used and has great aesthetic merit. As in all artistic displays, however, there is a constant demand for new techniques.
It is accordingly another object of this invention to provide a method and apparatus for introducing color into a fountain which is distinctly different from the floodlighting technique above mentioned and which will produce a distinctly different kind of manifestation of color in a fountain.
A further object of the invention is to provide an ornamental colored fountain and method of producing the same in which different areas of said fountain which are located at successively greater distances from the source of the fountain exhibit distinctly different colors in a subtantially constant pattern.
A still further object of the invention is to provide such a colored fountain and method in which a substantially constant color pattern is exhibited, yet in which this pattern has a movement perceptible to the observer in which the various succession of colored areas in the pattern travel in a given direction.
The manner of accomplishing the foregoing objects, as well as further objects and advantages will be made manifest in the following description taken in connection with the accompanying drawings in which:
Fig. 1 is a diagrammatic side elevational view of a preferred embodiment of the invention discharging continuously a spiral stream of water, this view illustrating the shape assumed by said stream at a given instant in the operation of the invention.
Fig. 2 is a diagrammatic elevational view similiar to Fig. 1 with the fountain of the invention producing a spiral stream of water in the same manner as shown in Fig. 1, but illustrating the optical illusion which is created for the observer by the play of lights from said fountain on said spiral stream.
Fig. 3 is an enlarged plan view of the fountain shown in Fig. 1 and taken on the line 3—3 therein.
Fig. 4 is an enlarged vertical sectional view taken on the line 4—4 of Fig. 3.
Fig. 5 is an enlarged detail view taken on the line 5—5 of Fig. 4.
Fig. 6 is a fragmentary horizontal sectional view taken on the line 6—6 of Fig. 4.
Fig. 7 is a wiring diagram of the invention.
Fig. 8 shows a modified drive system of the invention.
Referring specifically to the drawings, the invention is there shown as embodied in an apparatus 9 (Fig. 4) for performing the method of the invention to produce a colored fountain 10 (Fig. 2). Apparatus 9 includes a
5 housing 11, a circular upper wall 12 of which has a downwardly extending peripheral flange 13 providing lugs 14 to which a bottom housing wall 15 is secured as by screws 16. The apparatus 10 is supported by legs 17 fixed on the wall 15 and extending downwardly there
The upper wall 12 of the housing 11 has a central opening 18 a water-tight covering of which is provided by a window 19 formed of clear, transparent glass or plastic material which is held in place by a mounting
15 ring 20 secured to the upper face of the wall 12. Mounted concentrically on the wall 12 and extending upward therefrom is a light stack 25. This stack has a water drainage hole 26 provided therein near its lower end, and a hole 27 which is disposed opposite a slide aperture
20 28 provided in a pitman guide plate 29 which is secured to the outer face of the stack 25.
Fixed in an upper portion of the stack 25 is a nozzle supporting spider 31 having a central ring 32 which snugly receives a rubber packer 33 into which is upwardly
25 inserted a tubular nozzle 34 the lower end 35 of which is bent laterally to connect with a flexible hose 36 which extends outwardly through a hole 37 in the stack 25. Integrally connected with the nozzle 34 is a rod 38 which is axially aligned with said nozzle and has spaced collars
30 39 and 40 on its lower end. Surrounding the rod 38 between the collars 39 and 40 so as to be retained on said rod is a pitman head 41, this being mounted on one end of a pitman 42 which extends outwardly through holes 27 and 28 (Figs. 4 and 5) and has a
35 similar pitman head 43 mounted on its outer end.
Supported as by a bracket 44 on an outer face of the stack 25 in a vertical radial plane of the stack containing the hole 28 is an electric motor 45, the shaft 46 of which extends downwardly and is provided with a collar
40 47 having a crank pin 48 which pivotally receives the pitman head 43 which is retained in place thereon by a head 49 on said pin. It is thus seen that when the motor 45 is energized the collar 47 is rotated which reciprocates the pitman 42 in the guide 29 causing a
45 rotary motion to be imparted in a horizontal plane to
the lower end of the rod 38. This causes the nozzle
34 to oscillate about the vertical axis of the apparatus 9.
The lower wall 15 of the housing 12 has a central
hole 60 and a light well 61 is secured to the housing
50 bottom 15 by screws 62 in concentric relation with said hole. The light well 61 has ventilating holes 63 and has a light receptacle 64 mounted on a floor 65 of said well. An electric service cord 66 extends through a grommeted opening 67 in the light well 61 to the receptacle 64 to
55 energize an electric lamp 68 mounted in said receptacle. This lamp may be of any preferred type, although a builtin-reflector type flood lamp is shown in the drawings.
The bottom wall 15 has an opening 70 through which the shaft 71 of an electric motor 72 extends upwardly,
60 this motor being supported by brackets 73 which are secured by screws 74 to the bottom wall 15. Fixed on the upper end of the shaft 71 is a pulley 75.
Fixed on the wall 15 inside the housing 12 is an arm 76 from which a shaft 77 extends upwardly, said shaft
05 being located adjacent to the central hole 60 in the housing bottom wall 15. Rotatable on the shaft 77 is a filter wheel 80 which includes a hub 81, a rim 82 and spokes 83 which connect said hub and said rim. The hub 81 is externally grooved to cause this to serve as a pulley
Iq which is connected to the pulley 75 by an endless belt 84.
The spokes 83 of the filter wheel 80 divide the area
within the rim 82 into three equal sectors which are cov
