Abstract
Abstract For use in an automatic paper feeder supplying paper to an automatic typing system, apparatus is provided for selectively stacking the output sheet material from the automatic typing system in either their original input sequence order or in the reverse thereof. The apparatus includes an output tray and mounting means therefor adapted to support the output tray in either of two predetermined positions on the automatic paper feeder. Feed rollers eject the output sheet material vertically from the automatic paper feeder. Deflection means included on the output tray, together with the predetermined position of the output tray, determines the sequencing of the output sheet material.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
192 words
In a cut sheet feeding apparatus for use with an independently operable printing machine and having an input tray for storing a plurality of sheet members, sheet feeding means for feeding sheet members in singular sequence from said input tray to said printing machine, the improvement comprising: feed rollers operatively positioned to receive sheet members in singular sequence from said printing machine and feed said sheet members upwardly in a vertical direction; an output tray operatively positionable in either of a first or a second position to receive said sheet members from said feed rollers; deflection means attached to said output tray to deflect the vertically moving sheet members toward said output tray after passing through said feed rollers; and mounting means to operatively position said output tray in either of a first or a second position, whereby the output tray, when in a first position, receives sheets in a stacked sequence in the same order that the sheets were in when in the input tray, and, when in the second position, receives sheets in a stacked sequence in the reverse order that the sheets were in when in the input tray.
Claim 2
Dependent Claim
192 words
In a cut sheet feeding apparatus for use with an independently operable printing machine and having an input tray for storing a plurality of sheet members, sheet feeding means for feeding sheet members in singular sequence from said input tray to said printing machine, the improvement comprising: feed rollers operatively positioned to receive sheet members in singular sequence from said printing machine and feed said sheet members upwardly in a vertical direction; an output tray operatively positionable in either of a first or a second position to receive said sheet members from said feed rollers; deflection means attached to said output tray to deflect the vertically moving sheet members toward said output tray after passing through said feed rollers; and mounting means to operatively position said output tray in either of a first or a second position, whereby the output tray, when in a first position, receives sheets in a stacked sequence in the same order that the sheets were in when in the input tray, and, when in the second position, receives sheets in a stacked sequence in the reverse order that the sheets were in when in the input tray.
Claim 3
Dependent Claim
95 words
Apparatus as recited in claim 1 wherein said output tray comprises: a frame member; end brackets attached to opposite ends of said frame member and oriented essentially parallel to one another and essentially perpendicular to said frame member; a curved projection formed in each of said end brackets and projecting outwardly from said frame member; and a portion of each end member between said curved projection and said frame being formed to provide a cutout portion, said curved projection and said cutout portion forming that portion of the mounting means integral to the output tray.
Claim 4
Dependent Claim
58 words
Apparatus as recited in claim 2 wherein said mounting means further includes two pins on opposing sides of said automatic paper feeder and positioned a predetermined distance apart in a horizontal plane to coact with that portion of the mounting means on the output tray to position said output tray in either of a first or second position.
Claim 5
Dependent Claim
17 words
Apparatus as recited in claim 1 wherein said deflection means includes a predetermined number of spring fingers.
Claim 6
Dependent Claim
14 words
Apparatus as recited in claim 4 wherein said deflection means further includes a baffle.
