Abstract
Abstract A plant protection system which utilizes a housing and a heat source is disclosed. In one embodiment, the invention includes a truncated cone shaped housing which is positioned on the ground so as to surround the tree or other plant. The heat source may, for example, include a water pipe and spray emitter located within the housing to provide water in spray form near ground level adjacent the tree. A deep well may be used as the water source, thus providing water at a temperature higher than the ambient temperature. As the warm water spray rises within the housing, heat is transferred to the interior of the housing. An extension having side walls in the form of an inverted cone may be secured to the upper end of the housing to provide a further heating effect. Any of various designs and constructions for the housing and the extension may be employed. The heating means may also be provided from any of various sources and materials.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
163 words
Apparatus for protecting a tree or other plant against extreme weather conditions without ice formation through a water irrigation system having at least one conduit for supplying water to each said plant from a water pressure control means coupled to a supply of water at a temperature higher than ambient, comprising: a housing for positioning around said plant, said housing including a continuous side wall portion having upper and lower ends with an opening in the upper end of a size sufficient to allow said plant to pass through, and with an inwardly extending lip configuration around the periphery of said upper end, a portion of said conduit being received through said side wall portion of said housing so that said conduit portion is positioned in a generally central location within the lower end of the interior of said housing; and water spray emitter means attached to said conduit portion positioned in said housing in fluid communication with the interior of said conduit.
Claim 2
Dependent Claim
163 words
Apparatus for protecting a tree or other plant against extreme weather conditions without ice formation through a water irrigation system having at least one conduit for supplying water to each said plant from a water pressure control means coupled to a supply of water at a temperature higher than ambient, comprising: a housing for positioning around said plant, said housing including a continuous side wall portion having upper and lower ends with an opening in the upper end of a size sufficient to allow said plant to pass through, and with an inwardly extending lip configuration around the periphery of said upper end, a portion of said conduit being received through said side wall portion of said housing so that said conduit portion is positioned in a generally central location within the lower end of the interior of said housing; and water spray emitter means attached to said conduit portion positioned in said housing in fluid communication with the interior of said conduit.
Claim 3
Dependent Claim
24 words
The apparatus of claim 1 wherein said housing is in the form of a truncated cone with openings in the upper and lower ends.
Claim 4
Dependent Claim
24 words
The apparatus of claim 1 wherein said housing has a plurality of vertically extending, generally rectangular shaped ridges in the side wall portion thereof.
Claim 5
Dependent Claim
34 words
The apparatus of claim 1 wherein said housing includes a generally horizontal planar base extending around the periphery of the lower end of said side wall portion, said base having an upwardly concave curvature.
Claim 6
Dependent Claim
42 words
The apparatus of claim 1 wherein a vertical seam is provided in said side wall portion, said seam providing a closeable opening along the length of said seam, with at least one releasable fastener for closing the opening provided by said seam.
Claim 7
Dependent Claim
33 words
The apparatus of claim 1 further including an extension mounted on said housing and extending upwardly from the upper portion of said housing, said extension having an opening in the upper end thereof.
Claim 8
Dependent Claim
25 words
The apparatus of claim 6 wherein said extension is in the form of an inverted truncated cone mounted on the upper end of said housing.
Claim 9
Independent Claim
243 words
A method of protecting a tree or other plant against extreme weather conditions through a water irrigation system having at least one conduit for supplying water to each said plant from a water pressure control means coupled to a supply of water at a temperature higher than ambient, said method comprising: (a) positioning a housing around said plant, said housing including a continuous side wall portion having upper and lower ends with an opening in the upper end of a size sufficient to allow said plant to pass through, and with an inwardly extending lip configuration around the periphery of said upper end; (b) passing said conduit through the lower end of said side wall portion of the housing so that a portion of said conduit is positioned in a generally central location within the lower end of the interior of said housing; (c) positioning water spray emitter means on the conduit portion within said housing so that said spray emitter means is in fluid communication with the interior of said conduit; and (d) passing water from said water supply through said conduit and said spray emitter means at sufficient water pressure to provide water in atomized spray form to the interior of said housing, the water in spray form at a temperature higher than ambient being caused to rise along the interior of the side walls of said housing without formation of ice, thus transferring heat to the interior of said housing.
Claim 10
Independent Claim
243 words
A method of protecting a tree or other plant against extreme weather conditions through a water irrigation system having at least one conduit for supplying water to each said plant from a water pressure control means coupled to a supply of water at a temperature higher than ambient, said method comprising: (a) positioning a housing around said plant, said housing including a continuous side wall portion having upper and lower ends with an opening in the upper end of a size sufficient to allow said plant to pass through, and with an inwardly extending lip configuration around the periphery of said upper end; (b) passing said conduit through the lower end of said side wall portion of the housing so that a portion of said conduit is positioned in a generally central location within the lower end of the interior of said housing; (c) positioning water spray emitter means on the conduit portion within said housing so that said spray emitter means is in fluid communication with the interior of said conduit; and (d) passing water from said water supply through said conduit and said spray emitter means at sufficient water pressure to provide water in atomized spray form to the interior of said housing, the water in spray form at a temperature higher than ambient being caused to rise along the interior of the side walls of said housing without formation of ice, thus transferring heat to the interior of said housing.
Claim 11
Dependent Claim
16 words
The method of claim 8 wherein said housing is in the form of a truncated cone.
Claim 12
Dependent Claim
35 words
The method of claim 8 wherein a vertical seam is provided in the side wall portion of said housing, and wherein step (a) includes opening said seam sufficiently to fit the housing around the plant.
Claim 13
Dependent Claim
46 words
The method of claim 10 wherein at least one releasable fastener is provided for closing the opening in the housing provided by said seam, and including the step of closing said opening by the use of said fastener after the housing is positioned around said plant.
Claim 14
Dependent Claim
30 words
The method of claim 8 including the further step of positioning an extension on the upper end of said housing, said extension having an opening in the upper end thereof.
Claim 15
Dependent Claim
17 words
The method of claim 12 wherein said extension is in the form of an inverted truncated cone.
Claim 16
Dependent Claim
39 words
The method of claim 12 wherein the upper end of said housing has an inwardly extending, downwardly concave lip configuration and the lower end of said extension has an outwardly extending, upwardly concave curved lip around the periphery thereof.
