Abstract
Abstract An automatic plant watering device includes a container having an upwardly opening fill passage and a downwardly opening discharge passage, said container being supported on a hollow beam projecting upward from soil alongside the plant to be watered. The fill passage extends downward into the container and then turns upwardly in a substantially U-shaped pattern to a discharge end within the water storage portion of the container. Thus, water entering the container flows down and then up and over the inner terminus of the fill passage for storage and later use. The discharge passage comprises a duct which extends upward from near the bottom of the container and then downward in an inverted U-shaped pattern to terminate at an opening in the side of a standpipe. The standpipe projects from within the container downwardly through its bottom and upwardly to a point at least as high as the upper terminus of the inwardly opening fill passage, but below the top of the container. A tube extends from inside the support beam into the container and terminates near the top of the container, above the discharge end of the fill passage.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
179 words
A plant watering device comprising, a container having an upwardly opening fill passage for receiving water, said passage extending through the otherwise imperforate top of said container and including structural means for preventing air flow into the container through said passage subsequent to filling said container with water, said container including sidewalls extending from said wall to a bottom, said container being supported such that it is above the lowest extent of the roots of the plant it is to water; a stanDpipe projecting from below through the bottom of the container and extending upward within said container, said standpipe being hollow and defining a fluid passage from one end to the other; a tube for placing in fluid communication with a point in the soil near the lowest extent of the roots and extending into the container and terminating above the upper level of the standpipe; a discharge passage having its inlet near the bottom of the container, said discharge passage extending upward and then downward to connect in fluid communication with the lower part of said standpipe.
Claim 2
Dependent Claim
179 words
A plant watering device comprising, a container having an upwardly opening fill passage for receiving water, said passage extending through the otherwise imperforate top of said container and including structural means for preventing air flow into the container through said passage subsequent to filling said container with water, said container including sidewalls extending from said wall to a bottom, said container being supported such that it is above the lowest extent of the roots of the plant it is to water; a stanDpipe projecting from below through the bottom of the container and extending upward within said container, said standpipe being hollow and defining a fluid passage from one end to the other; a tube for placing in fluid communication with a point in the soil near the lowest extent of the roots and extending into the container and terminating above the upper level of the standpipe; a discharge passage having its inlet near the bottom of the container, said discharge passage extending upward and then downward to connect in fluid communication with the lower part of said standpipe.
Claim 3
Dependent Claim
27 words
The device of claim 1 including a hollow support beam connected to said bottom, a portion of said tube extending into the hollow of said support beam.
Claim 4
Dependent Claim
23 words
The device of claim 2 including a top having a sloping surface converging downwardly toward said upwardly facing opening of the fill passage.
Claim 5
Dependent Claim
23 words
The device of claim 1 including a top having a sloping surface converging downwardly toward said upwardly facing opening of the fill passage.
Claim 6
Dependent Claim
35 words
