MEANS FOR EXPELLING AIR FROM FOLDED NEWSPAPERS 1N A PEEss-coNvEYoR DELIVERY SYSTEM Filed OCT.. 2, 1955 FRANK A. SMETHURST BY i,

HIS ATTORNEY United States Patent O jointly Filed Uct. 2, 1963, Ser. No. 313,358 Claims. (Cl. 271-76) The present invention relates to newspaper press and conveyer delivery systems and, more particularly, to -an improvement therein wherein suitable means are provided for expelling the air from folded newspapers at a remote point in the delivery system such that chances of ink smearing `are avoided and stacking and further transport of the newspapers are aided. v

e In the past a number of different types of newspaper press and conveyer delivery systems yhave been developed. Generally common to these is conventional single or lmultiple press unit supplied with a heavy duty newspaper conveyer system which conducts a newspaper run upwar-dly from the press proper to'an extended overhead conveyer system of the overall newspaper conveyer. The overhead leg of the newspaper conveyer is generally quite long. This is for two reasons. In the iirst place, plant engineering principles generally indicate that final delivery points, stacking tables, andl binding equipment are best disposed remote from the actual press equipment and near the loading docks of the plant, where the bundles are delivered to trucks and other vehicles for distribution. In the second place, and most important, is a desire that there be a relatively long overhead run of the newspapers in order to allow sufficient time for the newspapers to dry prior to their stacking at la remote point.` For this purpose the presses and their built-in folding equipment 4are adjusted so that' a relatively loose fold of the individual papers is made immediately prior to the delivery of the newspapers to the conveyer system. Such loose folding avoids smearing and double printing an-d, additionally, permits air to be retained in the paper to aid in the drying process of the printing.

Heretofore, the binders have been relied upon to squeeze the air out of the newspapers at the time when the papers are bound into bundles by rope, wire, metal straps, or other means. However, the expelling of air from astack of newspapers is less elfective than if the newspapers are individually compressed, in the course of their run, to accomplish such expelling of air. Furthermore, in order for the newspapers to be delivered properly to the binders-it is important that they be stacked and conveyed to the binders. Personnel in newspaper plants readily .attest to the fact thatstacks of newspapers as are made up from the conveyer output of a newspaper run in -a conventional press and conveyer Iare often very unwieldly, and the stacks tend to become disarrayed during transit to the binders, particularly where changes of a direction .are encountered'in the travel path tothe binders. It would be a great advantage if the' air were automatically expelled from the newspapers after sufcient time has elapsed in order for newspapers from a run to dry and immediately prior to stacking the papers so that the stacks formed thereby will not lose their erectness `as they proceed along subsequent conveyer means to the binding equipment.

Accordingly, a principal object of the present invention is to provide an improvement in newspaper press con- 3,257,110 Patented June 21, 1966 veyer systems wherein appropriate means is provided near the delivery end of the conveyer system for squeezing air out of the newspaper run as it proceeds toward the sta-cking area.

A further object of the present invention is to provide means for automatically expelling air from la newspaper run at an advantageous point remote from the press proper of a press, newspaper'conveyer system.

A further object of the invention is to provide tension roller means adapted to bear upon the idler roller or power roller, or endless belting thereof, of a leg of the l for regulating the amount of pressure imposed upon a newspaper run in order to expell the air from the newspapers and to sharpen the leading or fold edges of the individual newspapers so that they can be stacked in the most appropriate manner.

The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further objects and advantages thereof, may best be understood `by reference to the following description, taken in connection with the accompanying drawings in which:

FIGURE l is a side elevation, partially in schematic form, of a conventional press and conveyer construction wherein the same employs the subject of the present invention, namely, a :suitable tension roller designed to exhaust air from the individual papers of a newspaper run at an advantageous point along the Iconveyer line of travel; in rFIGURE l1 the structure shown with respect to the heavy conveyer is somewhat simplified .in form, with the side plate'v thereof removed for clarity, the gearing, chain drive, and ancillary equipment likewise, to show simply the placement of idler and drive rollers, their belting, and the output delivery system of the conveyer.

FIGURE 2 is an enlarged fragmentary view, taken along the line 2-2 in FIGURE 1, illustrating that portion of the conveyer structure which accommodates the tension roller structure and adjustment means which is the subject of the present invention.

FIGURE 3 is a side elevation, principally in schematic lform and taken along the line 3 3 in FIGURE 2, of the iinal turn in the delivery system of the conveyer structure prior to the newspaper run reaching a retaining area and a terminal or near terminal conveyer belt.

In FIGURE 1 constant delivery press 10 is shown in block diagram form and is strictly conventional. A popular press of this type currently used isthe Goss press, as the same is known to the trade. 4

Heavy-duty newspaper conveyer 11 is likewise conventional and may take any standard form such as that currently manufactured by the Cutler Hammer Company and designated a model 70,'heavy-duty newspaper conveyer with electronic drive.

The upward-travel, initial leg I of the conveyer is ,disposed at 12 so as to receive pre-folded newspapers 4convenience -of illustration the overall conveyer`11 is shown broken at its dotted line conliguration at 13. The ldescending-travel, final leg 14 of the newspaper conveyer is shown somewhat in detail, but with conventional drive chains and sprockets and .similar hardware not being shown, this for convenience of illustration.

Of importance is the fact that the newspaper conveyer 11 will include a multiplicity of endless conveyor belts 15, 16, and 17, 18, and 19, 20, and so on, in order that the newspapers conveyed from press 12 may be carried by adjacent, slightly spaced, corresponding belting (Le. 15, 16 and 17, 18 and 19, 20) from the press 10 to a final area 21 which is defined by the conveyer and suitable resilient retainer fingers 22, one of which is illustrated. A suitable number of pulleys and rollers will be supplied the newspaper conveyer in a conventional manner in order that the paper run might turn corners as at A in FIGURE 1 s-o as to descend along the final leg 14 of the conveyer to area 21. There will be at least one drive (or driven) roller (e.g. 23) for each run of endless belting. All of the drive rollers are 'conventionally ganged together by suitable chain means (not shown) in order that the rotational movement of the drive rollers move with the same speed. .Idler rollers 24 are supplied along opposite sides of the newspaper run between endless belting -16, 17418, and so forth, in order to support the belting to accommodate a straight run of papers.

As the newspapers emerge from controlled delivery area 21 they are placed on a final conveyer belt 25 running on delivery rollers 26 and 27, at least one of which is driven, so that the newspapers arrive at bed 28 f-or further routing. Generally, men will be disposed at bed 28 to stack the papers in groups of lOs or 20s, for example, and place the stacked newspapers on another conveyor for bundling preparatory to l-oading trucks with the newspapers.

The structure thus far described is strictly conventional.

As before indicated, the difficulty of stacking the papers at or near bed 28, in a manner such that the stacks will not fall over or otherwise become disorganized in their routing to bundling apparatus or to further conveyer structure, is solved by the incorporation in the conveyer structure above described of. suitable tension roller means which is now to be explained. Again, the tension roller means is provided to sharpen the folded, leading edge of the newspapers as they come ldown the conveyer and, in addition, press out of the newspapers practically all of the air that would otherwise keep the individual newspapers quite bulky and unsuited for stacking and transport purposes.

The invention consists in the supplying of a tension roller 30 which, as shown in FIGURE 2, is appropriately journaled upon fixed shaft 31 by bearing means 32. Opposite extremities 33 and 34 of shaft 31 are received in and hence mounted to receptacles 35 and 36, these latter forming integral parts of arms 37 and 38. The arms are journaled by pivot bolts 39 and 40 and by means of boltreceiving means 41 and 42, the latter being secured to the conveyer frame 43.

The arms 37 and 38, accordingly, are freely swingable about the axes of pivot bolts 39 and 40, and the shaft 31 coupled thereby, by means of receptacles 35 and 36, is

,adapted for adjustment in slight, arcuate movements, and

will conform to contour of the paper run passing between conveyer belts 17 and 18, for example.

Aixed to arms 37 and 38 at receptacles 35 and 36, for example, are tension springs 4t) and 41, the remaining extremities of which are suitably mounted to adjustment lstraps 42 and 43. These adjustment straps are of metal, are provided with a plurality of longitudinally and mutually aligned apertures 44 and are also provided with respective handles 45 and 46. Mounted to the press frame proper are inwardly turned fingers 47 and 48 which are dimensioned to be received by any one of the several apertures 44 of the individual adjustment straps 42 and 43. A-ccordingly, the degree of force exerted by tension roller 30 or the endless belting which it carries and that side of the newspaper run which is opposite to a particular idler roller (see FIGURE 1) may be adjusted by the operator urging the handles 45 and 46 inwardly in the direction of the arrows shown so that inwardly-turned lingers 47 and 48 may engage different respective apertures 44 which are closer to 0r farther from the junctures of the adjustment straps 42 and 43 with their respective tension springs 40 and 41.

Now it may be that the rollers will be so designed that the belting thereof protrudes slightly outwardly away from the outer periphery of the rollers proper. This being the case, the above principle will still apply since the pressure upon the newspaper run, so as to squeeze as much air as possible out of the individual papers, may be controlled by the selected positioning of adjustment straps 42 and 43, this through the employment of handles 45 and 46 for convenience of the operator.

FGURES l and 3 illustrate the path of general newspaper travel, see arrows 46 in FIGURE 3. By way of further explanation, the endless belts are advantageously wire belting configured in the form of tightly wound tension springs (see 18, for example, FIGURE 2). This is strictly conventional in the art. Also conventional is the fact that the several rollers such as rollers 24 and 24 in FIGURE 2 are appropriately grooved to receive the several endless wire belts 18, for example. FIGURE 3 indicates the manner in which the handles 45 are moved so as to accomplish a tightening or loosening adjustment upon tension roller 30, as desired.

The press 10 when operating performs the complete printing, cutting and folding operation to produce a series of newspapers stepped somewhat in the pattern as indicated at N in FIGURE l. These newspapers are conveyed in a conventional manner by the conventional conveyer 11 along an upward leg I, an extended horizontal leg O, and finally down the vertical leg 14, passing all the while between adjacent conveyer belt series, for examples, 17, 18, until the papers pass underneath a lowermost roller 24 to be ejected outwardly in the direction of the arrows in FIGURE 3 so as to be disposed in area 21 underneath resilient retainer fingers 22. These retainer fingers, which are conventional, regulate the outward flow of the newspapers so as to allow them to adjust gradually to the new and horizontal orientation of the papers along final conveyer belt 25. Y

During the passage of the newspapers between adjacent series of endless conveyer belts 17, 18, the papers will traverse an area backed by idler roller 24. Disposed on the opposite side of the newspaper run at this point is tension roller 30 which with its conveyer belt is urged toward idler (or drive) roller 24 and hence along the opposite side of Athe newspaper run so as to compress the papers at this point, the degree of compression and pressure being adjustable by virtue of the provision -of adjustment straps 42, 43. Again, the tension roller 30 is adapted to swing in and out slight incremental displacements about the axes of the aligned stub-pivot axles or bolts 39 and 40. For thin newspapers, takeup will be made by releasing the adjustment straps 42 and 43 from their respective fingers 48 and 47 and then urging the corresponding handles 45 and 46 outwardly so that the fingers may engage new adjustment strap apertures 44. For heavier issues apertures 44 near the respective handles 45 and 46 will be selected for engagement with the two inwardly turned fingers 47 and 48.

FIGURE l illustrates the situation where a belt B may be used to couple, by means of pulleys P and P', power ,from the drive roller 23 to tension roller 30. This will be a desired condition to maintain where an especially heavy paper run, i.e., thick newspapers, is to be made. For most purposes, however, tension roller 30 can lsimply be an idler roller and uncoupled with respect to any drive source as indicated in FIGURE 3.

It has been noted in the above discussion and in the drawings that, preferabiy, the tensioning means for the tension roller of the present invention be disposed on both sides of the roller and the handles 45 and 46 adjusted simultaneously. WhileV this is desired, to reduce bearing and journal wear as much as possible, yet it would be quite possible to actuate a tension roller from one side onl lll of the lrollers, iboth drive and driven rollers, idler rollers and the tension roller of the present invention, may comprise single rollers or split coaxial rollers, as desired.

While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may bemade without departing from this invention in its broader aspects, and, therefore, thel aim in `the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of this invention.
