Abstract
Abstract An auger jogger assembly for a high speed item sorter pocket receptacle wherein a fixed shaft carries the armature of an electric drive eddy current motor. The fixed nonmagnetic reluctance member of which is a thin cylindrical metallic sleeve-like member press fitted into the cylindrical opening of a rotatable cylinder which carries about its periphery two volute or helical augers of differing diameters and spacings. The drive shaft and armature of the motor are fixed against rotation while the cylindrical reluctance member is secured within and rotatable with the rotatable cylinder. Energization of the motor armature causes the external cylinder to rotate effective to move item/documents into the pocket receptacle while vibrating the document sufficiently so as to reduce receptacle floor friction and force the items into a closely stacked bunch or pack.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
139 words
In a high speed document sorter apparatus having a plurality of pockets to which documents are sorted and compacted, a document packing system comprising: a hollow cylindrical member, located in each pocket of a document sorter apparatus, having raised helicies of different diameters; means for retaining a document in a fixed position, the retaining means being positioned adjacent the hollow cylindrical member; and a motor within each hollow cylindrical member for rotating the hollow cylindrical member to capture documents sorted to a pocket in the raised helicies and to compact those documents in the pocket against the retaining means; the hollow cylindrical member including an eccentric cross section relative to an axis about which the hollow cylindrical member rotates for vibrating the documents captured by the raised helicies to compact the documents in the pocket against the retaining means.
Claim 2
Dependent Claim
139 words
In a high speed document sorter apparatus having a plurality of pockets to which documents are sorted and compacted, a document packing system comprising: a hollow cylindrical member, located in each pocket of a document sorter apparatus, having raised helicies of different diameters; means for retaining a document in a fixed position, the retaining means being positioned adjacent the hollow cylindrical member; and a motor within each hollow cylindrical member for rotating the hollow cylindrical member to capture documents sorted to a pocket in the raised helicies and to compact those documents in the pocket against the retaining means; the hollow cylindrical member including an eccentric cross section relative to an axis about which the hollow cylindrical member rotates for vibrating the documents captured by the raised helicies to compact the documents in the pocket against the retaining means.
Claim 3
Dependent Claim
83 words
The invention of claim 1, wherein the raised helicies comprise a capture helix and a compacting helix, the capture helix increasing in diameter from being virtually flush with the surface of the hollow cylindrical member to engage an edge of a sorted document and urge that document to the compacting helix, the compacting helix maintaining a constant radius from an axis about which the hollow cylindrical member rotates to engage and move the document for compacting in the pocket against the retaining means.
Claim 4
Dependent Claim
60 words
The invention of claim 1, wherein the motor for rotating the hollow cylindrical member comprises an electric motor housed within the hollow cylindrical member, the electric motor having a stationary armature and an electrically conductive nonmagnetic shell interposed between the electric motor and the hollow cylindrical member to rotate the hollow cylindrical member in response to energizing the electric motor.
Claim 5
Dependent Claim
21 words
The invention of claim 3, wherein the electric motor includes a hollow mounting shaft through which the electric motor is energized.
Claim 6
Dependent Claim
28 words
The invention of claim 3, wherein the electrically conductive nonmagnetic shell interposed between the electric motor and the hollow cylindrical member is secured within the hollow cylindrical member.
Claim 7
Dependent Claim
176 words
In a high speed document sorter apparatus having a plurality of pockets to which documents are sorted and compacted, a document packing system comprising: a hollow cylindrical member, located in each pocket of a document sorter apparatus, having raised helicies of different diameters; meams for retaining a document in a fixed position, the retaining means being positioned adjacent the hollow cylindrical member; and a motor within each hollow cylindrical member for rotating the hollow cylindrical member to capture documents sorted to a pocket in the raised helicies and to compact those documents in the pocket against the retaining means; the raised helicies including a capture helix and a compacting helix, the capture helix increasing in diameter from being virtually flush with the surface of the hollow cylindrical member to engage an edge of a sorted document and urge that document to the compacting helix, the compacting helix maintaining a constant radius from an axis about which the hollow cylindrical member rotates to engage and move the document for compacting in the pocket against the retaining means.
Claim 8
Dependent Claim
176 words
In a high speed document sorter apparatus having a plurality of pockets to which documents are sorted and compacted, a document packing system comprising: a hollow cylindrical member, located in each pocket of a document sorter apparatus, having raised helicies of different diameters; meams for retaining a document in a fixed position, the retaining means being positioned adjacent the hollow cylindrical member; and a motor within each hollow cylindrical member for rotating the hollow cylindrical member to capture documents sorted to a pocket in the raised helicies and to compact those documents in the pocket against the retaining means; the raised helicies including a capture helix and a compacting helix, the capture helix increasing in diameter from being virtually flush with the surface of the hollow cylindrical member to engage an edge of a sorted document and urge that document to the compacting helix, the compacting helix maintaining a constant radius from an axis about which the hollow cylindrical member rotates to engage and move the document for compacting in the pocket against the retaining means.
Claim 9
Dependent Claim
46 words
The invention of claim 6, wherein the hollow cylindrical member comprises an eccentric cross section relative to an axis about which the hollow cylindrical member rotates for vibrating the documents captured by the raised helicies to compact the documents in the pocket against the retaining means.
Claim 10
Dependent Claim
25 words
The invention of claim 6, wherein the capture helix has about three threads per inch and the compacting helix has about eight threads per inch.
