Abstract
Abstract This invention relates to paper guides and paper stacking mechanisms, and more particularly to guides and stacking mechanisms for continuous paper forms of single or multiple ply of the variety known as fan-fold or accordion fold, during its passage from a printing device, over a guide, and through a stacking mechanism to a collecting table.

A fan-fold paper guide and stacking mechanism comprising: a table, which in operation is positioned immediately behind the device it serves, having a bottom shelf for holding a supply of fan-fold paper, a top shelf for receiving processed portions of said fan-fold paper, and an attachment means at opposite ends for holding an upper guide mechanism above the top shelf; an upper guide and stacking mechanism comprising a machine rest which sits upright on the printing device behind the platen and allows room for the fan-fold paper to pass underneath and into the printing device, a set of two or more guide rods which extend from the platen, near which they are attached to the machine rest, to a position over that center line of the top shelf which is parallel to the platen, where their end sections are inclined downward to an upright position, a pivot rod parallel to said centerline and above the top shelf, extending from end to end of the table and attached at its ends to the table, and attached in its middle portion to the downward projecting ends of the guide rods, a swing stop rod lying parallel to the pivot rod and in a horizontal plane with the pivot rod, having its ends bent towards the pivot rod and attached thereto so as to lie on the far side from the machine rest, and an overshoot stop, attached at its lower end to the middle portion of the swing stop, being upright and parallel to the upright portions of the guide rods and extending above the guide rods with its top portion inclined towards the machine rest over the gap between the pivot rod and the swing stop, said arrangement of parts providing that the fan-fold paper, upon leaving the printing device, will be directed towards the top shelf, will be directed downward over said shelf''s center line by the overshoot stop, and will be prohibited from swinging free and away from above the center line by the combined pivot rod and swing stop; a lower guide and stacking mechanism comprising a supporting base which sits on the top shelf with its axis parallel to the center line, having upright portions to support a pivot rod and an upright paper stop attached to one side parallel to the center line, a second pivot rod supported by said uprights on the base in a position also parallel to the center line, a pivoting guide lever attached at one end to the second pivot rod on the same side of the base as the paper stop and extending upwards on an incline to its other end which lies just below and past the gap between the pivot rod and swing stop, and a counterweight attached to the second pivot rod opposite the pivoting guide lever by means of counterweight support rods at such an angle that it lies on the top shelf while the pivoting guide lever is raised, said arrangement of parts providing that the pivoting guide lever will catch the fan-fold paper as it passes from the upper guide and direct it to the paper stop, after which the pivoting guide lever will hold the fan-fold paper in proper alignment as it tips to the shelf under the influence of the paper''s weight overbalancing the counterweight, thus insuring the proper stacking position for the fan-fold paper when it reaches the top shelf.
