ABSTRACT:
A machine for blowing loose thermal insulation into cavities in the walls, ceilings, and floors of buildings is contained within a smooth box-like housing that is easily moved about within a house on its own wheels and is easily transported to and from a job site. The housing encloses an equipment cavity and has a hopper located above the equipment cavity, but the hopper, into which the loose insulation is placed, is octagonal so that corner channels exist within the housing between the sides of the hopper and the corners of the housing. The equipment cavity at the bottom of the housing contains a motor which rotates an agitating wheel in the hopper, and that wheel has flexible tips that sweep the loose insulation over the floor of the hopper and into a feed hole in that floor. A grate extends through the hopper above the wheel to prevent access to the wheel in the bottom of the hopper. The feed hole in the floor of the hopper opens into a carburetor that is connected to a fan, all within the equipment cavity. The fan draws air and loose insulation through the carburetor, where they mix, and discharges the airstream that is generated into a hose which passes upwardly through one of the corner channels and out of the housing at the upper end of the hopper.
