Abstract
Abstract An ornamental fountain is comprised of a discharge nozzle and a mounting base through which water is supplied to the nozzle. Two pairs of water supply ducts communicate to a chamber within the base. One pair of ducts is coaxially aligned opposite each other diametrically of the chamber, and the other pair of ducts communicates tangentially of the chamber. Water for the fountain is supplied to the nozzle via either pair of ducts so that, depending upon the pair of ducts used, the fountain pattern has one or the other of two distinctly different aesthetic characteristics.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
143 words
A support base for an ornamental fountain nozzle and the like comprising: a. a housing defining therein a chamber having side walls, a ceiling and a floor; b. a first pair of coaxially aligned liquid inlet ducts through the housing and communicating with the chamber through the side walls thereof at opposed locations; c. a liquid outlet opening defined through the chamber ceiling and means in cooperation therewith for receiving a fountain nozzle with a liquid inlet opening thereof in communication with the chamber outlet opening; and d. a second pair of liquid inlet ducts defined through the housing and communicating with the chamber through the side walls thereof, the axes of the second pair of liquid inlet ducts being parallel to and spaced from each other, the openings of the second pair of ducts to the chamber being opposed across the chamber.
Claim 2
Dependent Claim
143 words
A support base for an ornamental fountain nozzle and the like comprising: a. a housing defining therein a chamber having side walls, a ceiling and a floor; b. a first pair of coaxially aligned liquid inlet ducts through the housing and communicating with the chamber through the side walls thereof at opposed locations; c. a liquid outlet opening defined through the chamber ceiling and means in cooperation therewith for receiving a fountain nozzle with a liquid inlet opening thereof in communication with the chamber outlet opening; and d. a second pair of liquid inlet ducts defined through the housing and communicating with the chamber through the side walls thereof, the axes of the second pair of liquid inlet ducts being parallel to and spaced from each other, the openings of the second pair of ducts to the chamber being opposed across the chamber.
Claim 3
Dependent Claim
44 words
Apparatus according to claim 1 wherein the effective distance along the length of the chamber perpendicular to the axes of the first inlet ducts from the openings thereof to the chamber outlet opening is at least equal to the mean diameter of the chamber.
Claim 4
Dependent Claim
80 words
Apparatus according to claim 1 wherein the base defines liquid flow controlling and directing means operatively associated with the flow path through the chamber from the first inlet ducts to the inlet opening of a nozzle received on the base for causing liquid flowing through the chamber to have an essentially laminar axial flow characteristic and an essentially uniform liquid flow pattern at the nozzle inlet opening when liquid is supplied to the chamber only through the first inlet ducts.
Claim 5
Dependent Claim
47 words
Apparatus according to claim 3 wherein the flow controlling and directing means includes proportioning the chamber to have a mean cross-sectional area in a plane parallel to the chamber floor which is substantially greater than the effective flow area to the chamber through the first inlet ducts.
Claim 6
Dependent Claim
48 words
Apparatus according to claim 1 including a fountain nozzle mounted to the base, and wherein the chamber is of circular configuration anD has a mean cross-sectional area in a plane parallel to the floor thereof which is at least twice the effective area of the nozzle inlet opening.
Claim 7
Dependent Claim
26 words
Apparatus according to claim 5 including controllable means for supplying liquid to the chamber either through the first inlet ducts or through the second inlet ducts.
