Abstract
Abstract A feeding mechanism for stacking and moving sheets of paper and the like in which sheets are moved to a stacking area where they are held stationary and accumulate in a stack. The stack is released and moved away from the stacking area after a predetermined number of sheets having accumulated in said stack. The moving mechanism includes upper and lower transport belts transversely offset from each other which are in different vertically adjacent planes to cause the belts to grasp and move the sheets. The stacking area is located between a sheet recording mechanism to record the number of sheets passing thereby and a stop mechanism to prevent forward movement of the stack. The sheet recording mechanism comprises a deflecting unit and the stop mechanism comprises a rotatable stop wheel.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
212 words
A feeding mechanism for stacking and moving sheets of paper and the like comprising means for moving said sheets along a transport path to a stacking area, said stacking area being substantially parallel to said transport path, said stacking area being substantially on the same plane as said transport path, means for holding said sheets stationary in said stacking area and accumulating said sheets in a stack which is substantially on a plane parallel to said stacking area, means for releasing said stack after a predetermined number of sheets have accumulated in said stack to permit the stack to be moved from said stacking area, said moving means comprising a plurality of upper and lower transport belts located in transverse offset relationship to each other, means for supplying said sheets between said upper and lower belts to cause the belts to grasp and move the sheets, a deflecting mechanism having a pair of spaced planes, one of which is a deflecting plane, one of said transport belts having a run in juxtaposed position adjacent said deflecting mechanism in a plane between the pair of spaced planes of the deflecting mechanism whereby the movement of a sheet past said deflecting mechanism will move the belt beyond the deflecting plane of the deflecting mechanism.
Claim 2
Dependent Claim
212 words
A feeding mechanism for stacking and moving sheets of paper and the like comprising means for moving said sheets along a transport path to a stacking area, said stacking area being substantially parallel to said transport path, said stacking area being substantially on the same plane as said transport path, means for holding said sheets stationary in said stacking area and accumulating said sheets in a stack which is substantially on a plane parallel to said stacking area, means for releasing said stack after a predetermined number of sheets have accumulated in said stack to permit the stack to be moved from said stacking area, said moving means comprising a plurality of upper and lower transport belts located in transverse offset relationship to each other, means for supplying said sheets between said upper and lower belts to cause the belts to grasp and move the sheets, a deflecting mechanism having a pair of spaced planes, one of which is a deflecting plane, one of said transport belts having a run in juxtaposed position adjacent said deflecting mechanism in a plane between the pair of spaced planes of the deflecting mechanism whereby the movement of a sheet past said deflecting mechanism will move the belt beyond the deflecting plane of the deflecting mechanism.
Claim 3
Dependent Claim
23 words
A feeding mechanism as set forth in claim 1 wherein said stacking area is located between said deflecting mechanism and a stop mechanism.
Claim 4
Dependent Claim
33 words
A feeding mechanism as set forth in claim 2 wherein said deflecting mechanism is adjustable lengthwise to permit the size of the stacking area to be adjusted to accomodate sheets of different sizes.
Claim 5
Dependent Claim
18 words
A feeding mechanism as set forth in claim 3 wherein said adjustable mechanism comprises a rack-and-pinion gear mechanism.
Claim 6
Dependent Claim
42 words
A feeding mechanism as set forth in claim 2 wherein said deflecting mechanism has a slot therein to receive the said run of said belt whereby the movement of a sheet past said slot will move the belt out of said slot.
Claim 7
Dependent Claim
19 words
A feeding mechanism as set forth in claim 2 wherein said stop mechanism comprises means for releasing the stack.
Claim 8
Dependent Claim
29 words
A feeding mechanism as set forth in claim 6 wherein said stop mechanism comprises a stop wheel having a notch therein adapted to prevent forward movement of the stack.
Claim 9
Dependent Claim
32 words
A feeding mechanism as set forth in claim 7 wherein said stop wheel is rotatable to move the notch away from the path of the stack in order to release the stack.
Claim 10
Dependent Claim
23 words
A feeding mechanism as set forth in claim 8 wherein said notch comprises a front wall and a wall to accommodate the stack.
Claim 11
Dependent Claim
22 words
A feeding mechanism as set forth in claim 9 wherein said notch front wall is flat and substantially perpendicular to said belts.
Claim 12
Dependent Claim
35 words
A feeding mechanism as set forth in claim 10 wherein opposed side rail assemblies area provided to be engaged by opposed side edges of each sheet moving thereby to maintain each sheet in proper orientation.
Claim 13
Dependent Claim
30 words
A feeding mechanism as set forth in claim 1 wherein said deflecting mechanism has an inclined deflecting surface which permits a sheet to be deflected thereover in its forward movement.
Claim 14
Dependent Claim
26 words
A feeding mechanism as set forth in claim 12 wherein the front wall of said deflecting mechanism is flat and substantially perpendicular to the said belts.
