Abstract

Abstract A fountain includes a closed fluid system having three superposed compartments. A first tube has an open end adjacent the bottom wall of the intermediate compartment and a nozzle end within the upper compartment. A second tube has an open end near the bottom of the upper compartment and extends downwardly into the bottom compartment. A third tube has an open end near the top wall of the bottom compartment and extends upwardly with an open end near the top wall of the intermediate compartment. A liquid is provided within the system of sufficient volume that, upon inversion of the device, it will fill the intermediate compartment and partially fill the normally upper compartment and, upon reinversion of the system to its upright position, will flow from the normally upper compartment through the second tube into the normally bottom compartment, displacing air from the bottom compartment into the intermediate compartment through the third tube, displacing liquid from the intermediate compartment through the first tube to cause a liquid jet into flow from the nozzle end into the upper compartment. Several embodiments of the fountain are disclosed. One embodiment includes an auxiliary compartment between the intermediate and bottom compartments to increase the pressure head causing the jet to flow. Another provides two closed fluid systems, one inverted with respect to the other, with compartments of the two systems interspersed in a vertical stack. An additional embodiment includes an upper compartment divided into two chambers with syphon means to transfer liquid received from the jet from the upper chamber to the lower chamber so that fluid may be transferred back through the second tube into the lower compartment. Toy and amusement devices of various types may be employed within the fountain for operation by or for use in conjunction with the jet.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 329 words
A fountain device comprising a closed fluid system including: a first compartment, a second compartment normally positioned above said first compartment, and a third compartment normally positioned below said first compartment; a first tube having an open end adjacent a lower wall of said first compartment, extending upwardly into said second compartment, and having an upper nozzle end within said second compartment; a second tube having an open end communicating with the second compartment at a level below the level of said nozzle end, extending downwardly into said third compartment, and having an open end adjacent to the bottom wall of said third compartment; a third tube having an open end in said first compartment adjacent the upper wall of said first compartment, and an open end in said third compartment adjacent an upper wall thereof; and a liquid within said system of sufficient volume that it will, upon inversion of the device, fill said first compartment and partially fill said second compartment and, upon reinversion of said device to its normally upright position, will flow from said second compartment through said second tube into said third compartment, displacing air from said third compartment into said first compartment through said third tube, displacing liquid from said first compartment through said first tube to cause a liquid jet to flow from said nozzle end into said second compartment, said second compartment being divided by a common wall into an upper chamber and a lower chamber, said first tube extending through said lower chamber into said upper chamber, a siphon tube positioned with an open end adjacent said common wall in said upper chamber and extending through said common wall, said open end of said second tube within said second compartment being adjacent the lower wall of said lower chamber, and a fourth tube having a lower open end within said lower chamber near said common wall and an upper open end within said upper chamber near the upper end thereof.
Claim 2
Dependent Claim 329 words
A fountain device comprising a closed fluid system including: a first compartment, a second compartment normally positioned above said first compartment, and a third compartment normally positioned below said first compartment; a first tube having an open end adjacent a lower wall of said first compartment, extending upwardly into said second compartment, and having an upper nozzle end within said second compartment; a second tube having an open end communicating with the second compartment at a level below the level of said nozzle end, extending downwardly into said third compartment, and having an open end adjacent to the bottom wall of said third compartment; a third tube having an open end in said first compartment adjacent the upper wall of said first compartment, and an open end in said third compartment adjacent an upper wall thereof; and a liquid within said system of sufficient volume that it will, upon inversion of the device, fill said first compartment and partially fill said second compartment and, upon reinversion of said device to its normally upright position, will flow from said second compartment through said second tube into said third compartment, displacing air from said third compartment into said first compartment through said third tube, displacing liquid from said first compartment through said first tube to cause a liquid jet to flow from said nozzle end into said second compartment, said second compartment being divided by a common wall into an upper chamber and a lower chamber, said first tube extending through said lower chamber into said upper chamber, a siphon tube positioned with an open end adjacent said common wall in said upper chamber and extending through said common wall, said open end of said second tube within said second compartment being adjacent the lower wall of said lower chamber, and a fourth tube having a lower open end within said lower chamber near said common wall and an upper open end within said upper chamber near the upper end thereof.
Claim 3
Dependent Claim 32 words
A fountain device as recited in claim 1, wherein at least one compartment of one of said fluid systems is positioned between a pair of compartments of the other of said systems.
Claim 4
Dependent Claim 31 words
A fountain device as recited in claim 2, wherein said third compartment of one of said systems is poSitioned between the first and third compartments of the other of said systems.
Claim 5
Dependent Claim 16 words
A fountain device as recited in claim 1 wherein said systems contain fluids of contrasting colors.
