Abstract

A device for dispensing loose, fibrous material comprising a housing having a reservoir disposed therein for containing the loose fibrous material to be dispensed. The housing has a passageway which extends from the reservoir through which the material is dispensed. At least one auger disc is rotatably mounted in the reservoir approximately adjacent the passageway. A motor or the like is provided to rotate the auger disc such that insulation material encountered by the auger disc is urged toward the passageway. Preferably a bar extends across the reservoir and is spaced from the edge of the auger disc such that as the auger disc rotatingly encounters the fibrous material the bar presents an obstacle to the material which is carried by the auger disc. A centrifugal pump is connected to the passageway by the auger disc. The suction inlet which is connected to the passageway is preferably offset from the center of the housing. A new method of blowing abrasive material is achieved by passing the material through the centrifugal pump.

Dependent claims

A device for dispensing fibrous material comprising:

centrifugal blower means having a radially offset inlet port and an outlet port;
a housing having a reservoir disposed therein for containing the fibrous material to be dispensed and a lower passageway which communicates said reservoir to said blower means inlet port;
at least one auger disc consisting of a sliced and spread disc having a toothed edge rotatably mounted and disposed in said reservoir approximately adjacent said passageway;
a bar extending across said reservoir parallel to the axis of rotation of said at least one auger disc and spaced adjacent said auger disc such that, as gravity urges fibrous material toward said auger disc and said auger disc rotatingly encounters said fibrous material, said bar presents an obstacle to fibrous material which is carried by said auger disc;
a ramp member extending from said bar upward to a side of said reservoir such that fibrous material above said bar is urged by gravity downwardly toward said auger disc;
and
means for rotating said auger disc such that insulation material encountered by said rotating auger disc is urged toward said passageway.
