Abstract
Abstract A sorting machine is provided for attachment to a copying machine to receive successive sheets from an outlet from the copying machine. The sorting machine has plural trays mounted to move progressively past the sheet outlet in opposite directions, the trays being relatively close together when positioned at either side of the outlet, but adjacent trays being widely spaced to accommodate the incoming sheets from the outlet. The trays are fed past and spaced at the outlet by driven members at opposite sides of the tray which engage and shift stacked trays in succession. The driver members are notched discs functioning as a linear Geneva movement. The remote ends of the trays are freely supported one on the other for relative longitudinal and pivotal movement. In certain forms, the remote tray ends are mounted one on the other by end pieces which have wedge surfaces causing the remote ends to be spaced apart responsive to longitudinal movement of the trays.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
206 words
In an improved sorting apparatus of the shiftable bin type including a frame structure having means for mounting the sorting apparatus on a copying machine at the sheet outlet fron the copying machine, sorting bins shiftable relative to one another to provide a wide sheet entry between bins at said outlet, and means for shifting the bins, said bins having ends remote from said outlet pivotally and longitudinally shiftably mounted one on the other and ends adjacent said outlet mounted for shifting movement past said outlet, said means for shifting said bins engaging successive bins at said ends adjacent to said outlet to move the latter successively pivotally from one side of said outlet to the other and causing relative longitudinal sliding movement of the bins, and including control means to intermittently effect operation of said shifting means following passage into successive bins from the copying machine of a selected number of sheets; the improvement wherein bearing means are provided on said ends remote from said outlet for increasing the space between said latter ends responsive to longitudinal movement of said bins in one direction and allowing movement of said latter ends towards one another responsive to longitudinal movement of said bins in the other direction.
Claim 2
Dependent Claim
206 words
In an improved sorting apparatus of the shiftable bin type including a frame structure having means for mounting the sorting apparatus on a copying machine at the sheet outlet fron the copying machine, sorting bins shiftable relative to one another to provide a wide sheet entry between bins at said outlet, and means for shifting the bins, said bins having ends remote from said outlet pivotally and longitudinally shiftably mounted one on the other and ends adjacent said outlet mounted for shifting movement past said outlet, said means for shifting said bins engaging successive bins at said ends adjacent to said outlet to move the latter successively pivotally from one side of said outlet to the other and causing relative longitudinal sliding movement of the bins, and including control means to intermittently effect operation of said shifting means following passage into successive bins from the copying machine of a selected number of sheets; the improvement wherein bearing means are provided on said ends remote from said outlet for increasing the space between said latter ends responsive to longitudinal movement of said bins in one direction and allowing movement of said latter ends towards one another responsive to longitudinal movement of said bins in the other direction.
Claim 3
Dependent Claim
40 words
Improved sorting apparatus as defined in claim 1, said bearing means being members on said bins having opposing portions providing a cam to shift said latter bin ends apart and allow movement of said latter bin ends towards one another.
Claim 4
Dependent Claim
47 words
Improved sorting apparatus as defined in claim 1, said bearing means being members on said bins having opposing portions providing a cam to shift said latter bin ends apart and allow movement of said latter bin ends towards one another, said opposing portions being of nesting configuration.
Claim 5
Dependent Claim
45 words
Improved sorting apparatus as defined in claim 1, said bins having on their ends adjacent said outlet stop tabs extending upwardly, and said bins being disposed on an incline relative to a line perpendicular to the path of travel of said ends adjacent said outlet.
