Abstract
Abstract Apparatus for transporting and cooling toner bearing sheets discharged from a fuser includes a structure having a pair of superposed sheet passageways, the entrance to the passageways being located at one end of the structure. The structure is moved so that successive sheets from the fuser are alternately fed to the passageways and fluidic means move the sheets through the passageways and out of the structure, the directions in which a sheet travels in entering and leaving the structure being, generally, orthogonal.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
74 words
Apparatus for transporting and cooling toner bearing sheets discharged from a fuser, comprising: a. a structure having a pair of superposed sheet passageways, the entrance to the passageways being located at one end of the structure; b. means for alternately feeding successive sheets from the fuser into said passageways; and, c. fluidic means for moving fed sheets toward the other end of the structure and thereafter in a transverse direction out of the structure.
Claim 2
Dependent Claim
74 words
Apparatus for transporting and cooling toner bearing sheets discharged from a fuser, comprising: a. a structure having a pair of superposed sheet passageways, the entrance to the passageways being located at one end of the structure; b. means for alternately feeding successive sheets from the fuser into said passageways; and, c. fluidic means for moving fed sheets toward the other end of the structure and thereafter in a transverse direction out of the structure.
Claim 3
Dependent Claim
33 words
Apparatus as defined in claim 1 wherein said means for alternately feeding includes a guide through which sheets are fed, and means for alternately aligning the entrance of the passageways with the guide.
Claim 4
Dependent Claim
25 words
Apparatus as defined in claim 2 wherein the structure is pivotally mounted and wherein said means for aligning include means for alternately pivoting the structure.
Claim 5
Dependent Claim
55 words
Apparatus as defined in claim 1 wherein said fluidic means includes a manifold located at the other end of the structure, the manifold having a first chamber communicating with one of the passageways and a second chamber communicating with the other of the passageways; and means for alternately providing a vacuum pressure in the chambers.
Claim 6
Dependent Claim
72 words
Apparatus as defined in claim 4 wherein said fluidic means further includes a second manifold, located on a side of the structure, the second manifold having a chamber communicating with said one of the passageways and a chamber communicating with said other of the passageways; and means for alternately providing pressurized fluid in the chambers of the second manifold, in each passageway pressurized fluid or vacuum pressure being applied in the alternative.
Claim 7
Dependent Claim
32 words
Apparatus as defined in claim 5 wherein said vacuum pressure draws fluid through the passageways in a direction which is transverse to the direction in which fluid is injected into the passageways.
Claim 8
Dependent Claim
34 words
Apparatus as defined in claim 6 wherein said means for alternately providing a vacuum pressure includes a vacuum pump and a valve for alternating pressure from the pump between the first and second chambers.
Claim 9
Dependent Claim
38 words
Apparatus as defined in claim 7 wherein said means for alternately providing pressurized fluid in the chambers of the second manifold includes a pressure pump and a valve alternatively providing fluid to the chambers of said second manifold.
Claim 10
Dependent Claim
49 words
Apparatus as defined in claim 5 wherein said means for alternately feeding includes a guide through which sheets are fed, and means for alternately aligning the entrance of the passageways with the guide, vacuum pressure being supplied to an aligned passageway and fluid being injected to the unaligned passageway.
Claim 11
Dependent Claim
25 words
Apparatus as defined in claim 9 wherein the structure is pivotally mounted and wherein said means of aligning include means for alternately pivoting the structure.
Claim 12
Dependent Claim
64 words
Apparatus as defined in claim 1 wherein said means for alternately feeding includes a guide positioned adjacent the discharge end of the fuser and means for alternately aligning the entrance of the passageways with the guide; and wherein said fluidic means include flexible means coupling the structure to the guide and means for providing fluid flow through the guide and alternately through the passageways.
