This invention relates to a perfectin web press capable of employing three we sat a time parallel with each other.

The principal objects of the invention are to provide for the supplying of the three webs to the press, printing on both sides of the webs that pass through the printing couples, and leading the webs from the press into the cutting and folding-mechanismand through to the delivery. The invention also involves improvements in details of the means for driving the cutting, collecting and folding mechanism and delivery fans,

and especially the driving of the folding and cutting cylinders absolutely positively from the printing couple and eliminating back lash which would break the web, and the driving of the drag rolls and other positiv'ely driven parts of the folding machine directly from the shaft of the collecting c linder, reducing the cost of construction. other feature of the invention consists in an alternative method of driving the delivery fans in such away that they can be reversed in a very simple manner to deliver in two directions, and also in the provision of practical means for mounting three web rolls in such close relationship to each other that they can supply the three webs to the press as near together at their in the ress.

Other objects and advantages of t e invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 is a central longitudinal sectional diagrammatic view of a double perfecting web press constructed in accordance with this invention showing original and final positions of the .web rolls;

ink from the fountain 12 through a fountain roll 13, delivering it to 'an ink cylinder 14 by a ductor roll- 17 and distributing it thereon by distributing rolls 15.- The usual form rolls 16 are shown for applying the ink to the plates. These parts, of course, are shown in four places on the particular press illustrated. The webs W are led through the printing way, being taken from three web rolls 18 at each end 1n this case. p The three webs from each end are fed inwardly toward the center through the printing couples and fed over the compensating rolls 19. 'From the compensating rolls the three webs from each end,

each handled separately, are brought into the Fig. 2. The webs from one endof the press can be brought over in contact with guide part of the machine in the usual is shown as applied to a Some of. these are indicated by full and dotted lines respectively in rolls 21 to the former normally used fortho the other end of the machine if desired as shown in dotted lines. Of course, the opposite operation could be accomplished also. Also instead of taking the web right down through the collecting mechanism from the former on the left-hand end of the press, the same can be carried over to the other colv lecting mechanism as shown in full lines in Fig. 2.

For the purpose of operating the folding mechamsm in exact'unison with the printin couples, I have provided one of each pair 0 comes the main driving shaft of the collecting, folding, and delivering mechanism as well as the press if driven directly from a motor as indicated-in Fig. 3. This shaft isprovided with a sprocket and sprocket chain 25 for driving, through gears 26, two drag rolls 2? on the same shaft. There-is also a gear 28 on the shaft 23 driving the gear 29 on the shaft of the cutting cylinder30 so as to drive these two cylinders in .erfect unison as usual. The press can'be riven from a shaft 55 at the other side if desired as indicated by dotted lines in Fig; 3. In either case back lash is eliminated so that no breaka e from the web from this cause need take place. v

The cutting cylinder shaft 31 is also provided with means for driving through a sprocket chain 32 the nipping rolls 33, and

delivering to a set adaptedto receive insuring their being driven positively in perfect unison. It is also provided with sprocket wheel and chain 34 for driving the delivery fan 35 on its shaft'36. The folding rolls 37 are driven by gears from a gear 28. In this-way all these parts are positively driven-in exact time with the press.

I have also provided'for a very simple change when it is desired to drive the fan 35 in the opposite. direction, so that instead of of delivery tapes 38 on one side of the fan, the products can be delivered to a different set of tapes 39.0n the opposite side. For this purpose the main drivin shaft 23 is-provided with a sprocket whee the chain 34.. Therefore, instead of connecting the parts upas shown in Fig. 8 just described "above the sprocket chain 34 is connected with the shaft 23 directand the fan is taken off its shaft 36and reversed thereon. Also the driving shaft 49 for the delivery tapes is wound over to the left. ,Then the parts aredriven as shown. in .Fi 9 and the products delivered on the a rig t side instead of on the left. This is readily accomph bed as will be obvious from the I factfthat" the shafts 23 and 31, "being geared directly together by two gears, one on each. shaft, rotate in opposite directions. The shaft 31 rotates faster thanthe shaft 23, and

it consequentlythetwo sprocket wheels on these (the shaft 36.

If

ports parts of room at each three web rolls were mounted end to end on their ordinary supports there would be a wide space between the edges of the webs. It would be poor economy to do this and widen out the press unnecessarily for it would necessitate making all the rolls and cylinders- 5 and 6, for supporting; the three web rolls The middle web 18 at each end of the press.

as usual, on a pair of standroll is mounted ards 41 having bearings for its shaft. ,The

shaftis provided with a pulley 42 by which it may be turned to get it up to web speed. These standards are provided with projections 43 having a gradually upwardly curved surface or track thereon. This permits 0 rolling the web roll in on the floor from the rear, shaft with these surfaces while the roll rests on the floor. Then the shaft is rolled up these inclined cam surfaces into the open-topped bearings taking'the roll with it.

' I also provide arms 44 on these standards projecting upwardly and having bearings for a pair of rods roll 46. Springs 47 are employed to hold the roll 46 up so-that the web W can be guided up away from the surface ofthev roll and ke t' taut.

For this purpose I provide tracks 50 located in all ment nearer the press thanthe central we roll 18. On these tracks I locate a pair of carriages 51' having rollers 52 resting on t 41 and provided two pairs of e'tracks. Each of; these carriages is provided with a standard 53 having'an open bearinglike the standard v with hinged loading levers,

54. These carriages are brought'outto the side iii-registration with-the 6 web roll, which is'theactual powound. The three are nism comprisin Then the levers 54 are turned down as .shown until its shaft engages these arms. Then these arms, either by hand or otherwise, are

turned upwardly to lift the roll and roll it carriage comes up against pins 48 which serve as stops for limiting its inward position so that it will register with the printing mechanism in the press. both of the side rolls are manipulated in the same way, and that they are supported on their carriages while they are being unin staggered relationship.

I have also shown a tension roller 56 mounted on a bracket on the frame of the press for guiding the web from this web roll. In this way a simple and convenient means is provided whereby three web rolls can .be located in proper position to deliver simultaneously to a tliree web width printing machine without necessitating themaking of the printing machine of excessive width.

Although I have illustrated and described only a single form of the invention and shown only a few'ways of using it, I am aware ofthe fact that modifications can be made in the relative arrangements and construction of the parts, and that the parts can be manipuw lated in other ways to lead the web through as desired without departing from the scope of the invention'as expressed in the claims. Therefore,- I do not wish to be limited in these respects but what I do claim is 1. In a perfecting web press, the'combination with two sets of printing couples, each set comprising two pairs of printlng cylinders, all of said cylinders being of a length to receive and print three separate newspaper webs simultaneously, and means for feeding three webs side by side to either set of couples separately, of a pair of folding, collecting and delivering devices, and means whereby eaclrweb from either set'of couples can be directed to either folding, collecting and de livering device.
