DUERKOB ATTORNEY United States Patent O 3,337,133 FOUNTAIN AND VALVE AND SPRAY APPARATUS THEREFOR Manfred F. Duel-kob, 7301 Whitehaven, St. Louis, Mo. 63123 Filed Aug. 23, 1965, Ser. No. 481,646 Claims. (Cl. 239-18) The present invention relates generally to an improved ornamental fountain, and more particularly to thel cornbination therein of a unique spray head and water-distribution valve especially adapted for use with a self-contained portable fountain of the .general type.
Heretofore, a satisfactory variety of fountain spray patterns was obtained generally only where a complex and costly water-distribution system, including numerous conduits, valves, connectors, etc., was employed. Where it was especially `desired to attain a completely self-contained, portable fountain, spray patterns suffered from lack of variety and insuicient illumination. In addition, fountains of this general type required separate power sources for varying the distribution of water and continuously changing the colored lighting for the spray patterns.
Therefore, among the objects of the present invention are the provisions of an illuminated, ornamental fountain and component parts therefor wherein: the initial production costs and subsequent maintenance costs are minimal; a satisfactory number of spray patterns may be provided with relatively uncomplicated parts and mechanisms; the same power source used to vary the Water distribution to the several spray nozzles is utilized to change the colored lighting projected upon the spray patterns; the illumination of the spray patterns, by means of a light source housed within the fountain itself, is greatly enhanced; and a predetermined restricted flow to the fountain nozzle maintains a minimum spray height.
These objects (as well as others apparent herein) are achieved generally by providing a hollow pedestal, which supports a basin. The basin serves as a water-tight top for an upper mechanism-housing portion of the pedestal and includes an outer saucer-like portion and an inner annular wall-like member, at the center of which is mounted my novel light-transmitting spray head. Flow conduits Within the light-transmitting spray head connect the spray nozzles with distribution outlets of my novel rotary-type water-distribution valve, which in turn is connected to a recircuating pump housed within the pedestal below the basin. a
A light source is also housed in the pedestal beneath the light-transmitting head. Interposed between the light source and the light-transmitting head is a color wheel type disc having a shaft mechanically interconnecting it with the water-distribution valve. An electric motor powers tbe shaft to synchronously drive the rotary-type valve and the color wheel.
My novel spray head includes inner and outer plastic plates which meet at mating surfaces, provided with conduit grooves which distribute the flow of water between flow-inlets in the inner plate and arrays of spray nozzles in the outer plate.
My novel Water-distribution valve includes a distribution chamber in a main body portion, an outlet plate,y
and a rotor which is positioned in the water-distribution chamber and is rotatably secured to a drive shaft. The rotor and outlet plate have a plurality of flow-passages and flow-outlets so spaced radially from the shaft that, upon rotation of the shaft, the rotor flow-passages are brought into and out of llow communication with the flow-outlets of the outlet plate, to provide varying ows to the several flow inlets of the spray head.
Utilization of the present invention will be apparent tov ice those skilled in the art from the following disclosure of a preferred embodiment as illustrated in the accompanying drawings, in which:
FIG. 1 is a plan view, partially broken away, of the ornamental fountain of the present invention;
FIG. 2 is across-sectional View of the ornamental fountain of FIG. 1 taken along the line 2-2;

The youtlet plate 90 shown has three flow-outlets 92, 94 and 96 spaced radially outwardly from the rotatable shaft 84, and angularly from each other, FIGS. 2, 4. These flow-outlets 92, 94 and 96 are connected in iiow communication lwith the iiow-inlets 58, 60 and 62 of the spray head 22 by means of the conduits 64, 66 and 68.
The valve rotor 88 shown has four flow-passages 98, 100, 102 and 104 which are spaced radially from the r0- tatable shaft 84 a distance which corresponds to the spacing of the flow-outlets 92, 94 and 96 `of the outlet plate 90. The flow-passages 98, 100, 102, 104 are angularly spaced from each other so that depending upon the angle of rotation of the rotor 88 with respect to the outer plate 90, a predetermined correspondence `with the flow-outlets 92, 94 and 96 will be obtained. Water flows through either a single flow-outlet at the outlet plate 94 or through any number of various combinations of the how-outlets.
While the iiow-outlets and flow-passages referred to 4rnay be of such shape as desired, I prefer to utilize circular outlets and passages, whose diameter is roughly equal to a 30 chord at ltheir radial distance from the shaft. Each r-otor flow-passage may thus be considered as passing twelve different stations on each cycle of rotation.
In the combination illustrated of three ow-outlets 92, 94, 96 with four rotor flow-passages 98, 100, 102, and 104, I use the following combination `of angular spacings:
The three flow-outlets at 90 and 210; and the four iiow-passages at 0, 60, 180 and 270. This cornbination yields the variation of spray patterns shown in FIG. hereafter referred to.
The valve rotor 88 has its under surface spaced to provide tolerance between the outlet plate 90, and tolerance between the periphery of the Valve rotor 88 and the inner wall surface of the body portion 70 of the valve 34 is also provided. This tolerance allows suflicient spacing between the valve parts to permit a desirable restricted ow of water from the valve inlet 78, through the water-distribution chamber 80, and around the peripheral portions of the valve rotor 88 to the flow-outlets 92, 94 and 96, even though none of the flow-passages are in registration with the How-outlets. Thus a single constant delivery pump 32 may be used, without undue back-pressure. Furthermore, for aesthetic reasons it may be desired to provide at least a minimum height of spray from each outlet at all' times. For this purpose I provide means for adjustment of this spacing. An adjustment screw 105 in the center of outlet plate bears upwardly against the inner shaft end 107 within the valve body 70. The cupped spring washer 91 biases the shaft downwardly in opposition to the screw 105. In this manner a `controllable flow of water is delivered to the flow-outlets to maintain sprays of a minimum height at the nozzle arrays 24, 26 and 28.
Electric motor and pump mechanisms The electric motor 40 which is mounted on the support shelf 30 has an output shaft (not shown) which is mechanically coupled through a spur gear 109 to a meshing ydrive gear 106 secured to the shaft 84. Upward and downward spacing of the shaft by the adjusting screw does not substantially affect the meshing of these gears.
A suitable electrical cable 108 is led in through a side opening in the hollow pedestal 12 to supply electrical power to the pump 32, the electric motor 40 which drives the valve and color wheel, an-d the centrally positioned light source 36.
A bracket 110 mounts the recirculating pump 32 to the support shelf 30. Preferably the recirculating pump 32 is a motor driven, constant-delivery vane-type pump having its inlet `connected through a curved hose 112 to a recirculating ow-inlet 114 located in the sloping portion of the wall-like member 18. A screen-type filter 116 is set Within the recirculating flow-inlet 114 to assure that debris which might fall into the basin 14 is prevented from being introduced into the working mechanisms of the ornamental fountain 10. The pump outlet is connected by means of a conduit 118 to the liow-inlet 78 of the water-distribution valve 34.
Operation Initially the upper basin 14 is filled with water. The location of the recirculation flow-inlet 114 in the upwardly and inwardly sloping wall-like member 18 and the curved hose 1112 prevent cavitation of the pump 34 at start-up. As the basin is gradually filled, air that otherwise would be entrapped is permitted to escape from the recirculation pump 32 and its connecting hose 112.
After the basin is filled with water, the electrical cable 108 may be connected to a source of electrical energy, such as a typical volt electrical outlet. When the electricity is applied to the vane-type pump 32, water is drawn through the hose 112 and delivered through the conduit 118 to the flow-inlet 78 of the water-distribution valve 34. Simultaneous with the energization of the pump 32, electricity is supplied to the electric motor 40 so that it drives the gear 106 to initiate the rotation of the valve rotor shaft 84. Rotation of the shaft 84 produces synchronous rotation of the valve rotor 88 and the color wheel 38. Water delivered to the water-distribution valve 34 through its iiow-inlet 78 enters the water-distribution chamber 80 from whence (except for the controlled restricted flow to all outlets as heretofore described) it passes through the flow-passages 98, 100, 102 and 104 of the rotating rotor 88 as they are brought into registration with the correspondingly spaced fiofwoutlets 92, 94 and 96 of the `outlet plate 90. The water emerging from the outlets is delivered to the nozzle arrays, 24, 26 and 28 either singly or in combination depending upon the particular registration of the How-passagesV of the rotor 88 with the flow-outlets of the plate 90.
A typical timed program for the spray patterns is illustrated by the table of FIG. 5, in which the letters C, I and O designate respectively the oW-outlets 92, 94 and 96 which connect respectively to the central nozzle array 24; the inner ring nozzle array 26; and the outer ring nozzle array 28. Further the numbers 1, 2, 3, and 4 refer to the first, second, third, and fourth rotor how-passages 98, 100, 102 and 104 respectively. With the rotor 88 and outlet plate 90 initially positioned as shown in FIG. 4, only 'the central nozzle 24 will be spraying (not taking account ofthe minimum ow to all nozzles); and the central nozzle will then reach maximum height. This results because only the now-passage 98 of the rotor 88 is in ow communication with the flow-outlet 92 of the plate 90. Shortly after the rotor 88 has begun rotating in the clockwise direction, now-passages 100 and 102 arebrought into registration with outlets 94 and 96, respectively. This permits water to ow from the water-distribution chamber 80 to the now-outlets 94 and 96 and thence to the nozzle arrays 26 and 28. Thus, upon a 30 angular movement of the rotor, by the motor 40 and its attendant gears, all three nozzle arrays are in operation. During the subsequent 30" interval the central nozzle turns off as passage 98 rotates beyond the fixed ow outlet 92. However, the inner and outer nozzle arrays 26, 28 continue to provide sprays of maximum height because the How-passages 100 and 102 remain in registration with the flow-outlets 94 and 96. After rotation through 60 none of the flow-passages 98, 100, 102 or 104 are in registration with the flow-outlets 92, 94 or 96. Even so, the tolerance between the parts of the water-distribution valve 34 permits water to be sprayed from all the nozzles at the adjusted minimum height. Further rotation of the rotor 88 and its flowpassages through 360 provides the sequence of spray patterns illustrated diagrammatically under the column labeled pattern of FIG. 5.
If, when one or only a few nozzles are flowing, they vspray to an excessive height, this may be reduced by turning the adjustment screw 105 to increase the spacing of the valve rotor 88 from the valve outlet plate 90. Such adjustment will divert a larger part of the flow to those nozzle arrays not then directly fed by the valve rotor.
Many modifications and variations are possible in view of the above teaching. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
