Abstract
Abstract A reproducing apparatus including an imaging surface. A first frame supports a cleaning system for removing residual material from the imaging surface. A second frame supports a remote sump for storing the residual material removed by the cleaning system. The residual material is transported from the cleaning system to the remote sump through a selectively connectable conduit. One of the frames is supported for movement relative to the other between a first position wherein the conduit is connected between the cleaning system and the sump, and a second position wherein the conduit is disconnected. Preferably, a valve is provided in the conduit which is responsive to the movement of the frame for selectively sealing off the conduit when it is disconnected.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
A reproducing apparatus comprising: an imaging surface; a first frame; means for removing residual material from said imaging surface, said removing means being supported by said first frame; a second frame; means remote from said removing means for storing said residual material removed from said imaging surface by said removing means, said storing means being supported in said second frame; means for transporting said residual material from said removing means to said storing means including selectively connectable conduit means extending between said removing means and said storing means; means for supporting one of said frames for movement relative to the other of said frames between a first position wherein said conduit means is connected between said removing means and said storing means and a second position wherein said conduit means is disconnected between said removing means and said storing means; and whereby upon movement of said one frame to said second position, said conduit portions are disconnected and upon movement of said one frame to said first position said conduit portions are connected together.
Claim 2
Dependent Claim
174 words
A reproducing apparatus comprising: an imaging surface; a first frame; means for removing residual material from said imaging surface, said removing means being supported by said first frame; a second frame; means remote from said removing means for storing said residual material removed from said imaging surface by said removing means, said storing means being supported in said second frame; means for transporting said residual material from said removing means to said storing means including selectively connectable conduit means extending between said removing means and said storing means; means for supporting one of said frames for movement relative to the other of said frames between a first position wherein said conduit means is connected between said removing means and said storing means and a second position wherein said conduit means is disconnected between said removing means and said storing means; and whereby upon movement of said one frame to said second position, said conduit portions are disconnected and upon movement of said one frame to said first position said conduit portions are connected together.
Claim 3
Dependent Claim
61 words
An apparatus as in claim 1, further including selectively actuable valve means for sealing said conduit to prevent the escape of residual material therefrom, and means for actuating said valve means to seal said conduit in response to the movement of said one frame to said second position wherein said conduit is disconnected between said removing means and said storing means.
Claim 4
Dependent Claim
66 words
An apparatus as in claim 2, wherein said transporting means includes an auger associated with said removing means, said auger being arranged to transport said residual material to said conduit means, and wherein said conduit means is arranged between said auger and said remote storing means so that said residual material transported to it by said auger, free falls through said conduit into said storing means.
Claim 5
Dependent Claim
28 words
An apparatus as in claim 3, wherein said conduit means includes a first portion associated with said removing means and a second portion associated with said storing means.
Claim 6
Dependent Claim
98 words
An apparatus as in claim 4, wherein said valve means is supported in said first portion of said conduit means and said conduit means has a rectangular cross-section, said valve means comprising a plate-like member including a first planar portion and a second planar portion inclined with respect to said first planar portion, and wherein said conduit means includes an inclined valve seat for mating with said valve member, said valve member being pivotally supported, and further including means for biasing said valve member into a normally closed position to seal off said first portion of said conduit.
Claim 7
Dependent Claim
49 words
An apparatus as in claim 5, wherein said apparatus comprises an electrostatographic reproducing apparatus further including means for forming an electrostatic image on said imaging surface, means for developing said image to render it visible, and means for transferring said visible image to a sheet of final support material.
