Abstract
Abstract An ornamental fountain comprises a housing which defines therein upper and lower chambers separated by a septum. A vertical duct member is connected to the housing to have its lower end in communication with the upper chamber. An open ended tube is disposed within the duct member and extends through the upper chamber and the septem to have its lower end communicating with the lower chamber. The upper end of the tube is disposed above the upper end of the duct member. Water inlet means are provided to the lower chamber. Also, water inlet means are provided to the upper chamber and are arranged with relation to the chamber to produce a spiral flow of water in the upper chamber and along the duct member around the tube to and through the upper end of the duct member.

Claim 3
Dependent Claim
23 words
A fountain according to claim 1 wherein the chambers and the duct member are coaxially aligned along a vertical axis of the fountain.
Claim 4
Dependent Claim
24 words
A fountain according to claim 2 wherein the outer diameter of the tube is substantially less than the inner diameter of the duct member.
Claim 5
Dependent Claim
71 words
A fountain according to claim 3 wherein the septum defines a hole therethrough concentric to the axis which is greater in diameter than the tube and through which the tube passes to communication with the lower chamber, and bearing means cooperating between the housing and a lower portion of the tube for accomodating rotation of the tube about its own axis and gyration of the tube relative to the fountain axis.
Claim 6
Dependent Claim
22 words
A fountain according to claim 4 wherein the bearing means comprises a bearing member carried by the tube in the lower chamber.
Claim 7
Dependent Claim
39 words
