Sheet stack jogging mechanism

Claim 2

In combination with a sheet receiving shelf adapted to receive a plurality of sheets and form uniform stacks therefrom, a sheet stack jogging means comprising; backup means mounted on the side of the shelf against which the stacks may be aligned. a jogging apparatus mounted for movement to and from the shelf at a first position on the opposite side of the shelf from the backup means, said jogging apparatus movable from the first position whereat it periodically jogs the sheets and a second position whereat it is substantially removed from the side of the shelf allowing easy access to the stack, and linking means connecting said bar to an eccentrically mounted, motor driven wheel whereby the bar is periodically moved, when in its first position, to and from the shelf moving the sheets into contact with the backup means assuring an even stack.

Claim 3

A jogging means as in claim 1 wherein the backup means is a second jogging apparatus whereby the stacks are jogged from both sides of the shelf and similarly can be removed from both sides of the shelf.

Claim 4

A jogging means as in claim 1 wherein the jogging apparatus is a single bar.

Claim 5

A jogging means as in claim 1 wherein the jogging apparatus is a plurality of bars operating simultaneously.

Claim 6

A jogging means as in claim 1 and further including an ajdusting device whereby the space between the jogging apparatus and the backup means may be varied to accommodate sheets of varying sizes.

Claim 7

A jogging means as in claim 1 and further including a means for absorbing the movement of the source of reciprocal motion without damage to the structure.

Claim 8

A jogging means as in claim 1 wherein the linking means and the source of motion are mounted beneath a bin comprising a plurality of stacked shelves and the jogging apparatus extends vertically upwardly substantially the entire vertical dimension of the shelf.

Claim 9

A jogging means as in claim 1 wherein ready access may be had to both sides of the shelf for removal of the stacks wherebY the device is of universal utility.

Claim 10

A jogging means as in claim 4, wherein each of the bars is driven by the source of reciprocal motion and are discrete.

Claim 11

In combination with a sheet receiving shelf adapted to receive a plurality of sheets and form uniform stacks thereon, a sheet stack jogger comprising; backup means mounted on one side of the shelf against which the stacks may be aligned, jogging means mounted adjacent the shelf opposite of and for movement toward and away from the backup means, an independent source of reciprocal motion mounted to the shelf and linked to the jogging means, said linking means comprising lever means mounted to receive motion from the source and having a fulcrum which is adjustable relative to the shelf to vary the distance between the jogging means and the backup means, rigid plate means pivotally mounted to the lever to receive motion therefrom and adjustably mounted to said shelf structure for selective positioning relative to the fulcrum of said lever means, rigid linking means interconnecting the plate means and the jogging means whereby the plate movement is transmitted to the jogging means and the adjustment of the fulcrum of the plate relative to the shelf varies the distance between the jogging means and the backup means allowing use of the mechanism with paper of a variety of sizes.

Claim 12

In combination with a sheet receiving shelf adapted to receive a plurality of sheets and form uniform stacks thereon, a sheet stack jogger comprising; backup means mounted on one side of the shelf against which the stacks may be aligned, jogging means mounted adjacent the shelf opposite of and for movement toward and away from the backup means, an independent source of reciprocal motion mounted to the shelf and linked to the jogging means, said linking means comprising lever means mounted to receive motion from the source and having a fulcrum which is adjustable relative to the shelf to vary the distance between the jogging means and the backup means, rigid plate means pivotally mounted to the lever to receive motion therefrom and adjustably mounted to said shelf structure for selective positioning relative to the fulcrum of said lever means, rigid linking means interconnecting the plate means and the jogging means whereby the plate movement is transmitted to the jogging means and the adjustment of the fulcrum of the plate relative to the shelf varies the distance between the jogging means and the backup means allowing use of the mechanism with paper of a variety of sizes.

Claim 13

A combination as in claim 10, wherein the jogging means comprises a single vertical bar on one side of the shelf and the backing means is a fixed surface.

Claim 14

A combination as in claim 10, and further including at least one moveable pivot to absorb the reciprocal motion in the event of a mechanical jam.

Claim 15

A combination as in claim 10, wherein the jogging means is adapted for movement to a position where it does not impede removal of the stacks of material.

Claim 16

A combination as in claim 10, wherein the backup means comprises a vertical bar which is reciprocal toward and away from the shelf providing a surface against which the stack may be aligned and further, providing a tapping action against the stack to assure proper alignment.
