A new apparatus for suspending and transporting particulate material is described. The apparatus is particularly useful for transporting and depositing thermal insulation into building spaces. The apparatus includes a conduit junction having a particle inlet conduit for the particulate material, an outlet conduit and an air inlet conduit to supply air under pressure for suspending the particulate material passing into the junction, e.g. from a closed receptacle such as a plastic bag in which the particulate material is stored. The air inlet conduit provides air at superatmospheric pressure to the closed receptacle, thereby placing the stored particulate material and the interior of the receptacle at or above the air pressure in the junction. The particulate material is then able to move into the junction without traversing an air current travelling in the opposite direction. The outlet conduit carries air and particulate material away from the junction to a delivery point. The outlet conduit preferably has connected to it a delivery conduit such as the flexible hose to carry the air and particulate material to a desired location. An air pervious member or screen is preferably mounted within the junction in a suitable location to prevent particulate material from travelling out through the air inlet; and a pressure relief valve is preferably provided to exhaust air exceeding a predetermined pressure.

As a new article of manufacture: An adapter for attachment to an upwardly directed air outlet of a portable air generating source to thereby form a base assembly for suspending and transporting particulate thermal insulation from a closed flexible shipment and storage bag directly through a delivery conduit into a building space, said adapter consisting of: (a) a conduit junction consisting of a downwardly directed air inlet conduit for communicative attachment to an upwardly directed air outlet of a portable air generating source, a particulate inlet conduit positioned in substantial alignment with said air inlet conduit and extending upwardly substantially diametrically opposite said air inlet conduit, and an outlet conduit extending between and at substantially a right angle to said air inlet and particulate inlet conduits, (b) an upwardly directed funnel-shaped extension united communicatively with said particulate inlet conduit, (c) a releasable retaining means for communicatively securing a closed flexible shipment and storage bag of particulate thermal insulation to said funnel-shaped extension in a manner permitting gravity drop of particulate thermal insulation from the bag into said funnel-shaped extension, (d) an air pervious member extending across the inside of said air inlet conduit of said junction to prevent particulate material from passing through said air inlet conduit, and (e) a pressure responsive air release means communicating with the interior of said air inlet conduit upstream from said air pervious member and opening to the atmosphere for permitting air to escape from said junction when the pressure therein exceeds a predetermined level above which rupture of a bag secured to said funnel-shaped extension would be endangered.
