Abstract
Abstract The display device has top and bottom members held separated by tubular columns or posts. Extending between the top and bottom members are spaced-apart parallel vertical strings or threads and liquid is placed in a tank in the bottom member and pumped therefrom through a tubular column to the top member where the liquid is directed to a distributor plate, which feeds the liquid evenly to the upper ends of the threads interconnecting the top member and the bottom member, the liquid flowing downwardly on said threads in the form of droplets to be received in the lower tank and recirculated by the pump to the top member. The display device may have surrounding the same various ornamentations such as flowers, plants, and spot lights may play upon the droplets as they move downwardly on the threads.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
A display device, including: vertically separated top and bottom members, the bottom member having a liquid tank and the top member having a circular tube provided with ports, means for directing liquid from the bottom tank to the circular tube, a distributor plate provided with radial corrugations below the circular tube for receiving liquid passed through the circular tube ports, a series of spaced apart vertical threads secured at their lower ends to the bottom member and tension means securing the threads to the top member, said threads at the top member engaging the valleys of the corrugations in the distributor plate.
Claim 2
Dependent Claim
102 words
A display device, including: vertically separated top and bottom members, the bottom member having a liquid tank and the top member having a circular tube provided with ports, means for directing liquid from the bottom tank to the circular tube, a distributor plate provided with radial corrugations below the circular tube for receiving liquid passed through the circular tube ports, a series of spaced apart vertical threads secured at their lower ends to the bottom member and tension means securing the threads to the top member, said threads at the top member engaging the valleys of the corrugations in the distributor plate.
Claim 3
Dependent Claim
155 words
In a display device, a top member and a bottom member, spaced apart and in alignment support posts interposed between the top member and the bottom member, said bottom member provided with a tank for holding a liquid, the top member provided with a tank and means for directing liquid from the tank of the lower member to the tank in the upper member, a series of spaced apart vertical threads extending between the top member and the bottom member and a distributor plate for receiving liquid from the upper tank and directing the liquid into contact with said threads, said liquid forming spaced-apart droplets on the thread for travel downwardly of said threads into the tank of the lower member, said distributor plate having a central plane portion and radial corrugations extending from said portion to the rim of the plate, the threads lying in the valleys of said corrugations adjacent the plate rim.
Claim 4
Dependent Claim
155 words
In a display device, a top member and a bottom member, spaced apart and in alignment support posts interposed between the top member and the bottom member, said bottom member provided with a tank for holding a liquid, the top member provided with a tank and means for directing liquid from the tank of the lower member to the tank in the upper member, a series of spaced apart vertical threads extending between the top member and the bottom member and a distributor plate for receiving liquid from the upper tank and directing the liquid into contact with said threads, said liquid forming spaced-apart droplets on the thread for travel downwardly of said threads into the tank of the lower member, said distributor plate having a central plane portion and radial corrugations extending from said portion to the rim of the plate, the threads lying in the valleys of said corrugations adjacent the plate rim.
Claim 5
Dependent Claim
17 words
The device of claim 2, and means for tensioning each thread between the top and bottom members.
Claim 6
Dependent Claim
154 words
In a display device, a top member and and a bottom member, spaced apart in alignement, support posts interposed between the top member and the bottom member, said bottom member provided with a tank for holding a liquid, the top member provided with a tank and means for directing liquid from the tank of the lower member to the tank in the upper member, a series of spaced apart vertical threads extending between the top member and the bottom member and a distributor plate for receiving liquid from the upper tank and directing the liquid into contact with said threads, said liquid forming spaced apart droplets on the thread for travel downwardly of said threads into the tank of the lower member, each pair of threads being looped at the upper ends thereof and coiled spring tensioning means secured to the loops for tensioning each pair of threads between the top and bottom members.
Claim 7
Dependent Claim
