Abstract

Abstract The paper feed mechanism disclosed has the capability of accepting two packs of sheet material or paper of two different sizes, such as letter and legal size, and selectively feeding sheets from one of the stacks in accordance with the condition to which the paper feed mechanism has been conditioned. The placing of the paper stacks on edge with the picker feed mechanism intermediate the stacks allows the feeding of the sheets by one picker or feed mechanism without the shifting of the paper packs from a first or second position. This also allows the feeding of the sheets without having to overcome gravity effects of the paper stack.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 233 words
A cut sheet paper feed apparatus for selectively feeding sheets from one of two packs having differing size characteristics comprising: a support means; first and second sheet pack holders supported by said support means for holding first and second sheet packs on one of said sheet packs'' edges and holding said packs in a spaced apart, generally parallel position with respect to each other and said packs having sheet''s faces in a position perpendicular to the horizonal; first and second biasing means for exerting a force simultaneously on each of said first and second sheet packs to urge said packs toward each other; friction reducing support means intermediate said packs to ease feeding of sheets from said packs; selectively operable and selectively engageable picker means for picking said sheets from one of said packs; transport means to receive said sheets from said picker means and transport said sheets toward the point of ultimate use; fixed convoluted sheet deflector means to orient said sheet from a generally vertical plane to a generally horizontal plane during the time said sheet is being transported by said transport means; timing means to intercept and release said sheet for further use at a predesignated time; whereby sheets are selectively fed from the adjacent surfaces of two sheet packs without the shifting of said packs and where said sheets are then transferred to a horizontal plane for continued use.
Claim 2
Dependent Claim 233 words
A cut sheet paper feed apparatus for selectively feeding sheets from one of two packs having differing size characteristics comprising: a support means; first and second sheet pack holders supported by said support means for holding first and second sheet packs on one of said sheet packs'' edges and holding said packs in a spaced apart, generally parallel position with respect to each other and said packs having sheet''s faces in a position perpendicular to the horizonal; first and second biasing means for exerting a force simultaneously on each of said first and second sheet packs to urge said packs toward each other; friction reducing support means intermediate said packs to ease feeding of sheets from said packs; selectively operable and selectively engageable picker means for picking said sheets from one of said packs; transport means to receive said sheets from said picker means and transport said sheets toward the point of ultimate use; fixed convoluted sheet deflector means to orient said sheet from a generally vertical plane to a generally horizontal plane during the time said sheet is being transported by said transport means; timing means to intercept and release said sheet for further use at a predesignated time; whereby sheets are selectively fed from the adjacent surfaces of two sheet packs without the shifting of said packs and where said sheets are then transferred to a horizontal plane for continued use.
Claim 3
Dependent Claim 36 words
The sheet feed apparatus of claim 1 wherein said selectively operable picker means further comprises a reversible power means operatively connected to said picker means for driving said picker means selectively in one of two directions.
Claim 4
Dependent Claim 31 words
The apparatus of claim 2 wherein said transport means comprises a continuously running belt for urging said sheet against said deflector means and for urging said sheets toward said timing means.
