No. 5,661,926 to Granger. None of these prior art patents show the combination of features disclosed in the present invention.
SUMMARY OF THE INVENTION
The invention is a Christmas tree watering apparatus which comprises a funnel, an upspout, two pieces of pipe which form a conduit, and a downspout, with a support stand supporting the conduit. The downspout is positioned into the Christmas tree stand so that water poured into the funnel runs down the conduit into the Christmas tree stand.
An advantage of the invention is that a person can water the Christmas tree without having to crawl under the tree to pour water into the Christmas tree stand.
Another advantage is that, unlike prior art devices, this apparatus does not need to be fastened to the Christmas tree, thus avoiding damage to the tree.
Another advantage is that the apparatus can be easily assembled for use and disassembled for storage.
