Abstract
Abstract A moving bin sorter has a plurality of sheet receiving trays supported for shifting movement to enlarge the space between adjacent trays at a sheet entry location to facilitate the feeding of successive sheets forming a set of sheets into the successive trays. The trays are formed to allow a portion of a stapler to be moved from a non-stapling position to a position for stapling a set of sheets in the successive trays while displacing the previously stapled sets in their respective trays with another portion of the stapler to enable positioning of the stapler in its operative position to staple a set of sheets. The stapler may be mounted for movement relative to the successive trays for applying staples at more than one location in each set.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
174 words
A sheet receiver of the moving tray type with an in-bin stapler, comprising: a frame structure, a plurality of horizontally extended trays arranged in a vertical stack in said frame structure, cam means for vertically sequentially displacing ends of said trays adjacent a sheet entry location to provide an enlarged sheet entry space between an adjacent pair of trays, means for sequentially operating said cam means in opposite directions as sheets are fed into the sheet entry space to form sets of sheets in said trays, a stapler having hammer and anvil portions forming a throat to receive an edge portion of a set of sheets in said trays, means for shifting said stapler towards and away from said trays for selectively positioning said sets of sheets in said throat for application of a staple, with one of said portions of said stapler extending into said enlarged space and the other of said portions of said stapler engaged with and displacing a set of sheets in a tray vertically spaced from said enlarged space.
Claim 2
Dependent Claim
174 words
A sheet receiver of the moving tray type with an in-bin stapler, comprising: a frame structure, a plurality of horizontally extended trays arranged in a vertical stack in said frame structure, cam means for vertically sequentially displacing ends of said trays adjacent a sheet entry location to provide an enlarged sheet entry space between an adjacent pair of trays, means for sequentially operating said cam means in opposite directions as sheets are fed into the sheet entry space to form sets of sheets in said trays, a stapler having hammer and anvil portions forming a throat to receive an edge portion of a set of sheets in said trays, means for shifting said stapler towards and away from said trays for selectively positioning said sets of sheets in said throat for application of a staple, with one of said portions of said stapler extending into said enlarged space and the other of said portions of said stapler engaged with and displacing a set of sheets in a tray vertically spaced from said enlarged space.
Claim 3
Dependent Claim
35 words
A sheet receiver as defined in claim 1, wherein said stapler anvil portion extends into said enlarged space, and said stapler hammer portion displace a set of sheets in the tray above said stapler throat.
Claim 4
Dependent Claim
35 words
A sheet receiver as defined in claim 1, wherein said stapler hammer portion extends into said enlarged space, and said stapler anvil portion displaces a set of sheets in the tray below said stapler throat.
Claim 5
Dependent Claim
22 words
A stapler as defined in claim 1, including means for horizontally shifting said stapler between a plurality of horizontally spaced stapling positions.
Claim 6
Dependent Claim
62 words
A sheet receiver as defined in claim 1 including infeed means for feeding sheets into said trays at said enlarged sheet entry space, said stapler being shiftable relative to said infeed means from a retracted position allowing sheets to be fed into said trays by said infeed means to a position at which sheets are disposed in the throat of said stapler.
Claim 7
Dependent Claim
83 words
A sheet receiver as defined in claim 1 including infeed means for feeding sheets into said trays at said enlarged sheet entry space, said stapler being shiftable relative to said infeed means from a retracted position allowing sheets to be fed into said trays by said infeed means to a position at which sheets are disposed in the throat of said stapler, and including means for horizontally shifting said stapler relative to said infeed means between a plurality of horizontally spaced stapling positions.
Claim 8
Dependent Claim
98 words
A sheet receiver as defined in claim 1, wherein said trays extend upwardly at an incline from said enlarged sheet entry space, and said portion of said stapler which displaces a set of sheets displaces a plurality of sets of sheets in a plurality of trays, said portion of said stapler which displaces said sets having a substantially vertically extended set displacing surface whereby stapled sets displaced by said stapler have their ends remote from the stapler offset to facilitate removal of stapled sets from said trays at the ends thereof remote from said enlarged sheet entry space.
Claim 9
Dependent Claim
46 words
A sheet receiver as defined in claim 1, wherein said trays extend upwardly at an incline from ends at said enlarged sheet entry space, said ends of said trays having an upturned wall forming a stop against which said sheets are aligned at their lower ends.
Claim 10
Dependent Claim
49 words
A sheet receiver as defined in claim 7, wherein said upturned wall has a clearance space for said portion of said stapler which displaces a set of sheets, and said tray has a notch at said clearance space in which a corner of said sets of sheets are stapled.
Claim 11
Dependent Claim
71 words
A sheet receiver as defined in claim 7, wherein said upturned wall has a plurality of clearance spaces spaced laterally of the tray for said portion of said stapler which displaces a set of sheets, and said tray has a notch at each of said clearance spaces in which portions of said sets of sheets are stapled, and including means for horizontally shifting said stapler to each of said clearance spaces.
Claim 12
Dependent Claim
37 words
A sheet receiver as defined in claim 1, including support means for said trays operable upon operation of said cam means to maintain the trays successively in the same angular relation to said stapler during stapling operations.
