Abstract
Abstract An insecticide distribution system and method consisting essentially of a pipe system having an inlet and an outlet and a plurality of nozzles along the pipe. In use, the pipe system is filled with insecticide at the inlet until insecticide is present at the outlet. The outlet is then closed off and the system pressured until the nozzles open at the preset pressure at which time the area near the nozzles will be sprayed with insecticide.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
160 words
In combination with a building, a fluid material distributing system comprising a pipe means disposed in said building, nozzle means, said nozzle means having one end connected to said pipe and the remaining end formed to create a spray when said fluid material passes therethrough, means for preventing escape of said fluid material from within said pipe and out of said nozzle means below a predetermined fluid pressure but responsive to fluid pressure above said predetermined amount to permit said fluid to escape therefrom, an inlet to said pipe means, an outlet to said pipe means, and valve means for selectively opening or closing said outlet means, whereby when said valve means is open, said fluid material entering said inlet means can fill said pipe means and when said valve means is closed, said fluid means can be pressured to above said predetermined pressure causing said fluid material to spray from said nozzle means when said predetermined pressure is realized.
Claim 2
Dependent Claim
160 words
In combination with a building, a fluid material distributing system comprising a pipe means disposed in said building, nozzle means, said nozzle means having one end connected to said pipe and the remaining end formed to create a spray when said fluid material passes therethrough, means for preventing escape of said fluid material from within said pipe and out of said nozzle means below a predetermined fluid pressure but responsive to fluid pressure above said predetermined amount to permit said fluid to escape therefrom, an inlet to said pipe means, an outlet to said pipe means, and valve means for selectively opening or closing said outlet means, whereby when said valve means is open, said fluid material entering said inlet means can fill said pipe means and when said valve means is closed, said fluid means can be pressured to above said predetermined pressure causing said fluid material to spray from said nozzle means when said predetermined pressure is realized.
Claim 3
Dependent Claim
36 words
A device as described in claim 1 wherein said means for preventing escape of fluid material from within said pipe and out of said nozzle means comprises a pressure operated valve built into said nozzle means.
Claim 4
Dependent Claim
43 words
A device as described in claim 1 wherein said means for preventing escape of said fluid material from within said pipe means and out of said nozzle means comprises a pressure operated valve inserted between the said pipe means and said nozzle means.
Claim 5
Dependent Claim
16 words
A device as described in claim 3 wherein said nozzle means comprises a plurality of jets.
Claim 6
Independent Claim
87 words
A method of distributing insecticide comprising: a. filling a pipe system completely with said insecticide, b. increasing the pressure in said pipe system until a predetermined pressure is reached, c. releasing said insecticide at said predetermined pressure into an area to be treated, d. releasing said pressure to pipe system and opening said pipe system to drain out all of said insecticide in said pipe system, and, e. repressuring said pipe system with air above the predetermined pressure releasing air through said system to clean said system.
Claim 7
Independent Claim
87 words
A method of distributing insecticide comprising: a. filling a pipe system completely with said insecticide, b. increasing the pressure in said pipe system until a predetermined pressure is reached, c. releasing said insecticide at said predetermined pressure into an area to be treated, d. releasing said pressure to pipe system and opening said pipe system to drain out all of said insecticide in said pipe system, and, e. repressuring said pipe system with air above the predetermined pressure releasing air through said system to clean said system.
Claim 8
Dependent Claim
20 words
A system as described in claim 1 wherein said pipe means are run through the wall joists of said building.
Claim 9
Dependent Claim
75 words
A system as described in claim 1 wherein said nozzle means comprises a pipe having a cone on one end and mounting threads on the other end, said means for preventing escape of fluid material below a predetermined fluid pressure comprises a valve seat over said pipe means mounted in said cone, and a spring biasing said valve seat over said pipe means so that the opening is closed until a predetermined pressure is reached.
Claim 10
Dependent Claim
15 words
A system as described in claim 1 wherein said nozzle means is a fog nozzle.
Claim 11
Dependent Claim
21 words
A method of distributing insecticide as described in claim 5 in which said insecticide is composed of powder mixed with air.
Claim 12
Dependent Claim
15 words
A system as described in claim 1 wherein said fluid material is a rodent poison.
Claim 13
Dependent Claim
14 words
A system as described in claim 1 wheRein said fluid material is a repellant.
