Abstract: The present invention contemplates an improved material moving apparatus which is particularly useful for blowing insulation material into portions of various structures. The apparatus includes: a hopper, having a chamber; a hopper blade assembly; a blower assembly; and a discharge conduit. The blower assembly includes an air lock positioned about a discharge opening from the hopper, the air lock including a plurality of rotating vanes which divide the air lock into an inlet chamber communicating with the hopper and an outlet chamber through which air is blown. The material is discharged into the hopper chamber, contacted by the hopper blade assembly, and discharged from the hopper chamber into the inlet chamber of the air lock for transfer to the outlet chamber thereof for discharging the material from the material moving apparatus.

Abstract: A fibrous materials filter device, particularly raw fibrous insulation material, which is used in combination with a centrifugal blower machine to remove projectible objects from the material while also avoiding damage to the blower impeller and housing. The filter device consists of a housing defining a volume and having a tangential input pipe and axial output pipe for affixure to the axial input of a centrifugal blower machine.
