MULTIPLE WEB-PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 574,493, dated January 5, 1897.

Application filed February 19, 1894;. Serial No. 500,679. (No model.)

To all whom it may concern:

Be it known that I, CHARLES POTTER, a citizen of the United States of America, residing at Plainfield, Union county, State of New Jersey, have invented certain new and useful Improvements in Multiple Web-Printing Machines, of which the following is a specification. I

This invention relates generally to rotary web-printing machines, and more particularly to that class in which a number of webs are perfected with a View of delivering an increased variety of products.

The present improvements are directed to a web-machine in which it is desired to associate with full-sized sheets half-sized sheets in making, for instance, products consisting of six, ten, or fourteen pages, which are made up in the one case of a four or full paged sheet with an inset of a two or half paged sheet, in the next case of two four or full paged sheets with an inset of a two or half paged sheet, and in the other case of three four or full paged sheets with an inset of a two or half paged sheet, as is well understood.

The improvements are also designed to effect an increase in the capacity of such machines and to provide a delivery mechanism by which such increased capacity may be effectually accommodated; and to these ends the invention consists in the novel structures and combinations hereinafter fully set forth.

As a more ready understanding of the invention will be had from a detailed description of a mechanism designed to practically carry out the improvements, such description will now be given, reference being had to the accompanying drawings, in which Figure 1 is an elevation in diagram of a multiple webprinting machine and delivery therefor provided with the improvements, certain tapes being omitted from the delivery. Fig. 2 is an end elevation of the delivery mechanism. Fig. 3 is a diagram of the webs with the interposed inset sheets. Fig. a is a view of a folded product. Fig. 5 is a diagram of an addition to the web-directing mechanism.

Referring to said drawings, the multiple web-printing machine in this instance consists of three distinct printing mechanisms A B C-it might be more or less, as desired arranged preferably one over the other and each adapted to perfect a web from a roll A,

B, and C for subsequent delivery, as by a delivery mechanism D. Each printing mechanism consists, as usual, of the first plate or type cylinder a and first impression-cylinder b, by which the web is printed on one side, and the second plate or type cylinder 0 and a second impression-cylinder d, by which the web is printed on the opposite side, with suitable inking mechanisms 6 f for the plate-cylinders. The web in each printing mechanism is led from the roll over suitable leading-rolls g g, thence between the cylinders a I), over the cylinder cl, and between it and the cylinder 0 and around a leading-roll h. The devices so far described are alike in each of the three printing mechanisms, and hence the description of those of one mechanism apply equally to the other printing mechanisms.

The printing mechanisms A and C are arranged to run at the same surface speed, and each web A C therefrom is led from the leading-roll 7L around a roll h, and thence one web A around a roll 1' and the other web 0 around a roll '6, and the two webs having thus been brought together or associated one over the other pass as a single two-ply web between the roll i to the delivery mechanism D.

- The rolls 11 t" are arranged out of contact one with the other, so that the two webs A 0 in passing around the said rolls, are not brought into close or nipping contact, but preferablyare held a slight distance apart, as shown in Fig. 1, such webs, however, gradually approaching one another andbeing finally brought into close ,contact in passing between the nipping-rolls 1' The printing mechanism 13 when halfsheets are to be formed is driven at one-half the surface speed of the other two mechanisms A C, and the web 13 thereof, which may be termed the supplement or half-sheet web, from the leading-roll h, passes between a pair of cutting or perforating cylinders j j,runnin g at the same surface speed as the mechanism B, by which the supplement-web is cut or perforated into half-sheets, which pass from said I,

cylinder into the space between the two webs A 0 turning the rolls t' i to become associated with and between said two webs and pass onward therewith as a single product. The space between the cutting or perforating cylinders j j may be occupied by upper and lower guides or other sheet conducting means to insure, if found necessary, the supplement orhalf sheets being directed between the two webs A C ,passin g around the rolls 1' 2'.

As the two webs A (J from the mechanisms A and O are traveling at twice the speed of the web 13 or sheets from the mechanism 13, it results that half or supplement sheets will be delivered between the two webs A (J at certain definite intervals apart, as indicated in Fig. 3. lVhen the supplement-web B is simply perforated in passing between the cylinders j j, the perforated or partially-severed web extends between the faster-runnin g webs A 0 and as soon as the end of the supplement-web is grasped between said two webs or nipped in passing'between the rolls 1' i it will be suddenly carried at the faster speed, so that a half-sheet is fully parted from the web and carried onward between the two webs. \Vhen the half-sheets are wholly severed from the supplement-web B such sheets as soon as they arrive between the two webs A O and lie against the lower web A will immediately partake of the faster speed of said two webs and be carried onward between them. The nipping eifect of the rolls 2' 1? will, to a great extent, be the same if the webs be led partially around one of the rolls, as i as in Fig. 1, the lower or other roll i being absent.

By arranging the printing mechanism B be tween the two mechanisms A and C, or by otherwise arranging said mechanism 13 and then conducting the supplement-web B to a point between the webs A C an exceedingly simple mode of insetting or associating the halfsheets with said two webs is provided, and by which said webs form the conducting means for the inset or half sheets, dispensing with the necessity for any tapes or sheet-conductor for properly carrying the half-sheets into position or association with the webs A 0 The associated webs with the inset sheets are directed from the rolls 1' '5 upward over a roll m, and thence downward over a longitudinal guide or folder it of any approved form and between a pair of folding or leading rolls 0 o. In passing over the roll on the associated webs and inset sheets are divided longitudinally into two portions 00 x, as by a slitter 19, so that two sets of associated webs with inset sheets pass between the rolls 0 0, and thus each set is so arranged as to pass into separate transverse cutting and, if desired, folding mechanisms. From the rolls 0 0 one of the longitudinally-divided webs 00 passes to the left between a pair of combined cutting and folding cylinders F of a wellknown type, and the cut and folded product, as in Fig. 4, passes thence between tapes 1 r for final delivery or to another or further folding device, according to the shape it is desired to impart to the delivered product. The other longitudinallydivided web :0 passes to the right between a similar pair of combined cutting and folding cylinders F, and the cut and folded product, as in Fig. 4, passes thence between tapes q 0" for final delivery or to another folding device, as may be deemed desirable, the form of the product from each pair of cylinders F F being the same or different, according to the requirements of the publisher.

In forming the products thus far described each printing mechanism will print duplicate matter side by side, so that the delivery mechanism will deliver two similar products simultaneously. This printing of duplicate matter and delivery of like products is not essential, as it is obvious that different matter may be printed side by side in each printing mechanism, so that the two products delivered by the delivery mechanism may be entirely different, designed either for association one with the other to complete a single paper or as completed products in themselves, as in newspapers printing editions in two languages. Vhere the products are different from one another, the supplement-machine B may be arranged to print on a half-width web, so that only one of the products will be provided with an inset or half sheet, forming in such case a ten-paged paper, while the other product will form an eight-paged paper. In like manner either one of the printing mechanisms A C may print on a half-width web and thus vary the size of the delivered product.

So,too, either one, two, or all of the printing mechanisms may be provided with associating web-turning bars, as indicated in Fig. 5 and in dotted lines, Fig. 1, wherein the lower web A in passing the leading-roll h is slit longitudinally by a slitter 8, one of the divided porti ons passing onward while the other is turned over two web-turning bars 25 t and thus transferred laterally under the other portion in a well-known manner.

By providing the supplement mechanism B with change-gearing it may be run at the same surface speed as the other mechanism A O to print and deliver full-sized sheets, in which case the cutting-cylinders jj may be rendered inoperative to sever or partially sever the passing web.

It will be observed that the slitter 12 may be omitted, in which case the webs passing over the longitudinal folder it will be folded centrally and may then pass from the rolls 0 0 bodily into either one of the pair of combined cutting and folding cylinders F F for proper manipulation and delivery.

hat I claim is- 1. In a multiple printing-machine, the combination with three printing-machines superimposed one above the other for printing independent webs, of means for operating the center printing-machine and feeding the web therefrom at a speed slower than the other two machines, adjacent leading-rolls separated a distance apart for the uppermost and lowermost webs, other leading-rolls in biting contact situated a distance from the firstmentioned rolls, and a web-severing device for the center web interposed between the center printing-machine and said first-mentioned leading-rolls, as set forth.

2. In a multiple printing-machine, the combination with three printing-machines superimposed one above the other for printing three independent Webs, a slitter for longitudinally slitting one of the webs, and turning-bars for associating the divided portions of said web, of means for operating the center printingmachine and feeding the web therefrom at a speed slowerthan the other two machines, adjacent leading-rolls separated a distance apart for the uppermost and lowermost webs, other leading-rolls in biting contact situated a distance from the first-mentioned rolls, and a web-severing device for the center web interposed between the center printingmachine and said first-mentioned leading-rolls, as set forth. 7

3. In a multiple printing-machine, the combination with three printing-machines superimposed one above the other for printing independent webs, of means for operating the center printing-machine and feeding the web therefrom at a speed slower than the other two machines, adjacent leading-rolls separated a distance apart for the uppermost and lowermost webs, other leading-rolls in biting contact situated a distance from the firstmentioned rolls, a slitter for dividing the associated webs and interposed sheets longitudinally, a longitudinal guide or folder for bringing the divided portions together, and a delivery mechanism for each portion, as set forth.

In witness whereof I have hereunto signed my name in the presence of two witnesses. CHARLES POTTER. Witnesses: S. T. GALLUP,
