Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
103 words
A fibrous materials filter device for use in combination with a power driven centrifugal blower apparatus of the type having an axial materials input and tangential materials output, comprising: housing means having top, bottom and sides and forming an enclosure, and including an input opening in generally tangential direction to said enclosure as formed at a side bottom location, and an output opening in axial direction to said enclosure as formed centrally through said top; an orifice formed in said input opening adjacent its tangential juncture to said enclosure; and means for connecting said housing means output to said blower apparatus materials input.
Claim 2
Dependent Claim
103 words
A fibrous materials filter device for use in combination with a power driven centrifugal blower apparatus of the type having an axial materials input and tangential materials output, comprising: housing means having top, bottom and sides and forming an enclosure, and including an input opening in generally tangential direction to said enclosure as formed at a side bottom location, and an output opening in axial direction to said enclosure as formed centrally through said top; an orifice formed in said input opening adjacent its tangential juncture to said enclosure; and means for connecting said housing means output to said blower apparatus materials input.
Claim 3
Dependent Claim
29 words
A device as set forth in claim 1 wherein said means for connecting comprises: cylindrical comb means including locking slot for rigid affixure to said blower apparatus materials input.
Claim 4
Dependent Claim
44 words
A device set forth in claim 2 wherein said housing means further includes: second cylindrical comb means formed around the top outer edge of said housing means for rigid abutment against the adjoining blower apparatus when said locking slot is engaged in rigid affixure.
Claim 5
Dependent Claim
29 words
A device as set forth in claim 1 wherein said means for connecting comprises: flexible base means of preselected length interconnecting said housing means output and said materials input.
Claim 6
Dependent Claim
26 words
A device as set forth in claim 1 wherein said housing means forms an enclosure that is a body or revolution having top and bottom parallel.
Claim 7
Dependent Claim
25 words
A device as set forth in claim 1 which further includes: flexible base means of preselected length rigidly connected to said housing means input opening.
Claim 8
Independent Claim
138 words
A device for transporting and depositing fibrous material such as home insulation, comprising in combination housing means having a top, bottom and sides and being formed to include a tangential input opening at one end with an axial output at the opposite end; an orifice formed in said housing means adjacent to said tangential input opening; centrifugal blower means having an axial input and a tangential output; power means for driving said centrifugal blower means; means sealingly connecting said housing means axial output to said blower means axial input; flexible hose means connected to said housing means tangential input and extending a preselected length from communication with a reservoir of said fibrous material; and second flexible hose means connected to said blower means tangential output and extending a preselected length for depositing said fibrous material in predetermined manner.
Claim 9
Independent Claim
138 words
A device for transporting and depositing fibrous material such as home insulation, comprising in combination housing means having a top, bottom and sides and being formed to include a tangential input opening at one end with an axial output at the opposite end; an orifice formed in said housing means adjacent to said tangential input opening; centrifugal blower means having an axial input and a tangential output; power means for driving said centrifugal blower means; means sealingly connecting said housing means axial output to said blower means axial input; flexible hose means connected to said housing means tangential input and extending a preselected length from communication with a reservoir of said fibrous material; and second flexible hose means connected to said blower means tangential output and extending a preselected length for depositing said fibrous material in predetermined manner.
