Apparatus for insecticide application

Claim 2

Apparatus for applying bulk insulation combined with insecticide in the void spaces of a building structure, comprising: first hopper means receiving and continually agitating a quantity of bulk insulation; second hopper means containing a supply of insecticide; rotary metering means receiving insecticide from said second hopper means and continually isolating selected incremental amounts per unit time; air pressure means conducting said incremental amounts of insecticide for input into combination with said agitating bulk insulation; and pneumatic means for transporting said combined bulk insulation and insecticide from said first hopper means to an operator position for placement in the void spaces.

Claim 3

A apparatus as set forth in claim 1 wherein: said insecticide is a blatticide powder.

Claim 4

A apparatus as set forth in claim 2 wherein: said blatticide consists largely of boric acid.

Claim 5

Apparatus for application of bulk insulation combined with insecticide into void spaces of a building structure, comprising: hopper means receiving and comminuting bulk insulation; second hopper means receiving a selected insecticide; metering means receiving insecticide from the second hopper and isolating a measured amount adjacent an outlet port; conduit means connecting from said outlet port to said hopper means; an air source moving said insecticide measured amount through the outlet port and conduit means into the hopper means; an air source directing air at increased pressure through said hopper means to move comminuted bulk insulation and insecticide toward a hopper outlet; and an applicator hose connected to receive combined bulk insulation and insecticide under air pressure for transport to said void spaces.

Claim 6

Apparatus for application of bulk insulation combined with insecticide into void spaces of a building structure, comprising: hopper means receiving and comminuting bulk insulation; second hopper means receiving a selected insecticide; metering means receiving insecticide from the second hopper and isolating a measured amount adjacent an outlet port; conduit means connecting from said outlet port to said hopper means; an air source moving said insecticide measured amount through the outlet port and conduit means into the hopper means; an air source directing air at increased pressure through said hopper means to move comminuted bulk insulation and insecticide toward a hopper outlet; and an applicator hose connected to receive combined bulk insulation and insecticide under air pressure for transport to said void spaces.
