Abstract
Abstract An apparatus for exterminating pests such as roaches, ants and the like including a vaporizer unit for converting a liquid pesticide into a vaporous state and a distribution system for directing the pesticide in its vaporous state to desired locations. The distribution system will permit the vaporous pesticide to be emitted during the operation of the vaporizer unit. A portion of the pesticide which is reconverted into a liquid state during distribution will accumulate on the distribution system to produce a residual exterminating potential.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
179 words
An apparatus for exterminating pests such as roaches, ants and the like within a building structure comprising: a. a housing having a chamber therein; b. reservoir means carried on said housing for storing a supply of pesticide and directing said pesticide into said housing chamber; c. vaporization means located within said housing chamber for receiving and converting said pesticide into a vaporous state; d. blower means carried on said housing which communicates with said housing chamber for forcing the pesticide vapors from said chamber; e. means for distributing said vapors to remote locations within said building structure, said means for distributing including at least one tubular woven member being adapted to permit said vapors to escape through its walls along its entire length, some of said vapors being reconverted into a liquid state as the pesticide passes through the walls of the tubular member so that a residue will accumulate on the tubular member, said residue permitting the means for distributing to maintain its exterminating potential for an extended period of time; and f. activating means for said apparatus.
Claim 2
Independent Claim
179 words
An apparatus for exterminating pests such as roaches, ants and the like within a building structure comprising: a. a housing having a chamber therein; b. reservoir means carried on said housing for storing a supply of pesticide and directing said pesticide into said housing chamber; c. vaporization means located within said housing chamber for receiving and converting said pesticide into a vaporous state; d. blower means carried on said housing which communicates with said housing chamber for forcing the pesticide vapors from said chamber; e. means for distributing said vapors to remote locations within said building structure, said means for distributing including at least one tubular woven member being adapted to permit said vapors to escape through its walls along its entire length, some of said vapors being reconverted into a liquid state as the pesticide passes through the walls of the tubular member so that a residue will accumulate on the tubular member, said residue permitting the means for distributing to maintain its exterminating potential for an extended period of time; and f. activating means for said apparatus.
Claim 3
Dependent Claim
59 words
The apparatus of claim 1, wherein said tubular woven member having a preselected weave pattern which will permit a predetermined volume of vaporous pesticide to be emitted from the tubular member during a specific period of time, said tubular member collecting a residual portion of said pesticide resulting from the reconversion of said vaporous pesticide into a liquid state.
Claim 4
Dependent Claim
14 words
The apparatus of claim 2, wherein said tubular woven member is made of nylon.
Claim 5
Dependent Claim
63 words
The apparatus of claim 2, wherein said vaporization means includes: a. a heating element carried within said housing; and b. a vaporizer coil encircling said heating element, said coil having an inlet end associated with said reservoir means for receiving said liquid pesticide and a plurality of spaced exhaust apertures along its length through which the vaporous pesticide escapes into the housing chamber.
Claim 6
Dependent Claim
90 words
The apparatus of claim 1, wherein said reservoir means includes: a. a container for recEiving a supply of liquid pesticide; b. a conduit having one end connected to said container and extending into said housing cavity, the other end of said conduit having a restricting aperture to regulate the flow of said pesticide into said vaporization means; and c. valve means associated with said container and said conduit and operated by said activating means to permit and restrict the flow of said liquid pesticide from said container into said conduit.
Claim 7
Dependent Claim
66 words
The apparatus of claim 1, wherein said vaporizer means includes: a. a heating element carried within said housing cavity; and b. a vaporizer coil encircling said heating element, said vaporizer coil having an inlet end associated with said reservoir means for receiving said liquid pesticide and a plurality of spaced exhaust apertures along its length through which the vaporous pesticide is emitted into the housing chamber.
Claim 8
Dependent Claim
88 words
The apparatus of claim 6, wherein said reservoir means includes: a. a container which carries a supply of liquid pesticide; b. a conduit having one end connected to said container and extending into said housing, the other end of said conduit having a restricting aperture to regulate the flow of said liquid pesticide into said vaporizer coil; and c. valve means associated with said container and said conduit and operated by said actuating means to permit and restrict the flow of pesticide from the container into said conduit.
Claim 9
Dependent Claim
58 words
The apparatus of claim 7, wherein said tubular woven member having a preselected weave pattern which permits a predetermined volume of vaporous pesticide to be emitted from said tubular member during a specific period of time, said tubular member collecting a residual portion of said pesticides resulting from the reconversion of said vaporous pesticide into a liquid state.
Claim 10
Dependent Claim
58 words
The apparatus of claim 7, wherein said activating means includes: a. switch means for energizing said valve means, said heating element and said blower means; and b. timer means for de-energizing said valve means, said heating element and said blower means at preselected times, said blower means being de-energized subsequent to said valve means and said heating element.
Claim 11
Independent Claim
130 words
A method of exterminating pests such as roaches, ants and the like through an initial application of a pesticide in a vaporous state and a residual application of said pesticide over an extended period of time including the steps of: a. positioning a tubular woven member in a desired location frequented by such pests; b. converting a liquid pesticide into a vaporous state; c. directing said vaporous pesticide through said tubular woven member so that the vaporous pesticide is emitted along the entire length of said member; and d. accumulating a residue of said pesticide on said member due to a reconversion of a portion of said pesticide from a vaporous to a liquid state, said residue permitting said member to maintain exterminating properties for an extended period of time.
Claim 12
Independent Claim
130 words
A method of exterminating pests such as roaches, ants and the like through an initial application of a pesticide in a vaporous state and a residual application of said pesticide over an extended period of time including the steps of: a. positioning a tubular woven member in a desired location frequented by such pests; b. converting a liquid pesticide into a vaporous state; c. directing said vaporous pesticide through said tubular woven member so that the vaporous pesticide is emitted along the entire length of said member; and d. accumulating a residue of said pesticide on said member due to a reconversion of a portion of said pesticide from a vaporous to a liquid state, said residue permitting said member to maintain exterminating properties for an extended period of time.
