Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 96 words
Apparatus for watering and humidifying plants comprising: a tray for holding water, support means within said tray, a mat on said support means at least a part of which is adapted to dip into the tray to communicate with the water therein, said mat formed by a composite of a lower layer of a fabric of a pile-type material to conduct water by a wicking action and an upper layer of a harder finish than the lower layer to conduct water but at a lesser rate than said lower layer and to protect the lower layer.
Claim 2
Dependent Claim 96 words
Apparatus for watering and humidifying plants comprising: a tray for holding water, support means within said tray, a mat on said support means at least a part of which is adapted to dip into the tray to communicate with the water therein, said mat formed by a composite of a lower layer of a fabric of a pile-type material to conduct water by a wicking action and an upper layer of a harder finish than the lower layer to conduct water but at a lesser rate than said lower layer and to protect the lower layer.
Claim 3
Dependent Claim 17 words
Apparatus as in claim 1 wherein said upper and lower layers of said mats are bonded together.
Claim 4
Dependent Claim 16 words
Apparatus as in claim 1 wherein said bottom layer of said mat is a non-woven fabric.
Claim 5
Dependent Claim 14 words
Apparatus as in claim 3 wherein said non-woven fabric is of a polyester material.
Claim 6
Dependent Claim 13 words
Apparatus as in claim 3 wherein said upper layer is a woven fabric.
Claim 7
Dependent Claim 11 words
Apparatus as in claim 5 wherein said woven fabric is nylon.
Claim 8
Dependent Claim 46 words
Apparatus as in claim 1 wherein said support means comprises: a platform on which said mat rests, a plurality of posts for supporting said platform, said platform being spaced from at least one edge of the tray to permit water to be placed into the tray.
Claim 9
Dependent Claim 45 words
Apparatus for watering and humidifying plants comprising: a tray for holding water, and support means within said tray for holding a mat which conveys water by capillary action, said support means comprising a base member having a plurality of spaced resilient fingers extending upwardly therefrom.
Claim 10
Dependent Claim 45 words
Apparatus for watering and humidifying plants comprising: a tray for holding water, and support means within said tray for holding a mat which conveys water by capillary action, said support means comprising a base member having a plurality of spaced resilient fingers extending upwardly therefrom.
Claim 11
Dependent Claim 16 words
Apparatus as in claim 8 wherein said fingers are arranged in clusters on said base member.
Claim 12
Dependent Claim 18 words
Apparatus as in claim 8 wherein said support means and said tray are formed as an integral unit.
Claim 13
Dependent Claim 12 words
Apparatus as in claim 8 wherein said support means is of plastic.
Claim 14
Dependent Claim 102 words
Apparatus for watering and humidifying plants comprising: a tray for holding water, support means formed by a base member having a plurality of spaced resilient fingers extending upwardly therefrom, a mat on said resilient fingers of said support means at least a part of which is adapted to dip into the tray to communicate with the water therein, said mat formed by a composite of a lower layer of a fabric having a pile to conduct water and an upper layer of a material which also conducts water but of a harder finish than the lower layer to protect the lower layer.
Claim 15
Dependent Claim 102 words
Apparatus for watering and humidifying plants comprising: a tray for holding water, support means formed by a base member having a plurality of spaced resilient fingers extending upwardly therefrom, a mat on said resilient fingers of said support means at least a part of which is adapted to dip into the tray to communicate with the water therein, said mat formed by a composite of a lower layer of a fabric having a pile to conduct water and an upper layer of a material which also conducts water but of a harder finish than the lower layer to protect the lower layer.
