DOUBLE MULTIPRESS.

SPECIFICATION forming arser Reissued Letters Patent No. 12,016, dated July 22, 1902. Ol'iginal No. 701,120, dated May 27, 1902. Application, for reissue filed June 6, 1902. Serial No. 110,484-

To all whom, it may concern:

Beit known that I, HENRY A. \VISE WOOD, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Double Multipress, of which the following is a specification.

sists of two beds, on which the forms are The object of my present invention is to improve the style of printing-machine which is known as the flat-bedtraveling-cylinder web-printing machine. This machine conplaced, and two traveling impression-cylinders, one for each bed. Suitable guides and web-manipulating devices are provided, so that the web will be'perfected in its passage through the machinethat is, printed on both its sides. The operation is such that the web stands stationary relatively to the forms during impression, the cylinders and guides carrying moving loops or waves of web and presenting the web to the forms, and r the web is shifted or fed forward when the cylinders reverse off the forms in either direction. Presses of this character have been coinmercially made so that four forms can be placed abreast on each of the two beds, and by this arrangement either a four, six, or eight paged paper can be produced. It has been found impractical, however, to make the machine produce more than an eight-paged paper, because if the machine is made wider 'the cylinders will spring and will not give good impressions, and, on the other hand,- if more than oneform is placed in line the speed of the machine will be reduced, owingto the increase of stroke of the cylinders required. There has been a call, however, for a machine which will make a largersized paper or product, the call for which machine has not been satisfactorily supplied. To supply the demand fora machine of this character, it has heretofore been proposed to arrange two machines side by side and associate the two webs issuing from such machines to make the largerpaged products. It has also been proposed -in an another case to arran e two machines end to end and to associate lahe two webs to get the larger-paged products. These arrangements, however, have been very undesirable on account 'of the great floor-space required, the complication of the mechanism for bringing the products together, and the inconvenience in getting around and handling such arrangements.

Mypresent invention aims to supply a machine which shall produce not only the four, six, or eight paged paper of the single machine, but also the ten, twelve, fourteen, or sixteen paged papers now wanted without decreasing the speed.

two fiat-bed traveling-cylinder web-perfecting presses one directly over the other and in providing mechanism so that two webs can be led through the machine and perfected and then associated and folded to form the desired ten, twelve, fourteen, or sixteen paged papers. 1

The preferred form in which I practice this invention consists in providing two separate driving mechanisms for the four cylinders", one mechanism being used to operate the two lower cylinders and the other driving mechanism being used to operate the two upper cylinders. These two driving mechanisms may be set to work in unison with each other at one hundred and eighty degrees to each other, or quarteringthat is, at ninety degrees to each other. If the two driving mechanisms are set quartering,-the two lower cylinders will bein impression orprinting while the twoupper cylinders are reversing, and vice versa. If this arrangement is used, the double machine will run very smoothly and easily.

l'n the preferred form of machine I run the webs through in a peculiar way. One web is run so as to be printed on one side by'tho percylinder. The second web is run through the machine so as to be printed on one side by the second cylinder and on its other side by the third cylinder. By this arrangement the two printed webs will issue from the machine "above the same, so that they can be easily associated. It will be seen that by this construction one web is practically within the loop ofthe other web in the machine. If this arrangement is used in a machine in which the two driving devices for the cylinders are set quartering, it is necessary to provide a compcnsat ing looping mechanism at the front lower cylinder and on its other side by the up-,

My presentinventionconsistsin arranging two web-rolls will be kept low down,and the 455 end of the machine which will compensate for the relatively different movements of the cylinders, so that the feed of each web will take place around only one cylinder at a time.

Rollers, turners, and slitters are provided, so that the two webs can be slit and associated to make any desired double produce, and a suitable folding device is provided, so that the associated webs may be cut into sheet form and given any desired number of folds.

When it is desired to run this machine to handle only one web to make a four, six, or eight paged product, the upper driving mechanism is disconnected and the lower machine only is used. When this operation takes place, I may us'ewhat was the feeding-in device for-the upper web as the feeding-out device for the single web simply by driving what was the feeding-in device in the opposite direction and actuating what was the feedingin looper oppositely, so that the same will chine.

form a feeding-out looper, Another way I may lead the single web out is to lead the same dred and eighty degrees to each other, I can dispense with the compensating looping mechanism at the front end of the machine. Thus a paper of any desired number of even pages up to sixteen may be produced with but little trouble, and the machine may be changed to proluce the different-paged products in a few moments, and the device occupies the floor-space of but one machine.

According to a first modified form of-my' invention I lead the first web to the two lower cylinders and the second web to the two up per cylinders and turn the webs out at the side of the machine by suitable turners and associate them by suitable rollers and fold them by a folding device, which preferably is arranged at right angles to the machine proper.

A second modified form of my invention consists in arranging the machine as last described aud in running the webs out beyond the web-rolls and folding them beyond the webrolls. While this is a good arrangement, it is not as desirable as the preferred form, as

it necessarily involves putting the upper webroll into the machine between two webs and because of the extra floor-space required to do this and to arrange the folding device beyond the web-rolls.

The preferred form of my invention is that previously described as the principal form. Referring to the accompanying seven sheets of drawings, which'illustrate the various ways in which my invention can be practiced, Figure 1 is a side elevation of the complete ma- Figs. 2 and 3 are detail views of the gearing. Fig. 4 is a sectional elevation of the end of the machine.

Fig. .6 is a view similar to Fig. 4 with the driving mechanism set at one hundred and eighty degrees to each other. Fig. 7 is a diagrammatic view similar to. Fig. 6 with the driving mechanisms set to work in unison. Fig. 8 is a diagrammatic sectional view of the first modified form of my invention. Fig. 9 is a plan view of the turners used in the device shown in Fig. 8. Fig. 10 is a diagrammatic sectional view of the second modified form of my invention, and Fig. 11 is a plan view of the turuers used in the device shown in Fig. 10.

Referring to the drawings and in detail, I will first describe the preferred form of my invention-that is,-the form wherein-one web is within the loop of the other web. The various arrangements of this preferred form are shown in the first' five sheets of the drawlugs.

In detail, A designates the framing of the press.

B, C, D, and E represent four form-beds, which preferably are arranged horizontally and in di lferent horizontal planes. F, G, H, and Idesignate the four traveling impression-cylinders, which coact with said beds.-

J represents the lower carriage-frames for cylinders F and G, and K the upper carriageframes for cylinders H and I.

"T wov web-trolls W and Ware mounted at The web w from websroll W first passes around guide-rollers l0 and 11 to a feeding-in drum 12, which has a suitable set of tapes coacting therewith to continuouslyfeed the web into the press.

-The web then passes around a feedinge in looping-r'oller13, which is actuated by earns 14 on the shaft of the feeding-in drum 12. The web then passes to guide-roll 15, mounted in the carriage-frames J under the 'lower impression-cylinder F, and up over guide 16, also mounted in frames J. The web then passes around web guides or rolls 17 and 18, attached to the frame A, then around a compensating looper 19, and then. around a web guide or roll 20, secured to the frame of the machine. The webthen passes to guide 21, mounted in. frames K, under the upper impression-cylinder I, and around the guide 22,

also arranged in said frames K. The web then passes around a feeding-out looper 23, actuated from cams 24, to a. continuously running feeding-out drum 25, coacting with which is a suitable set of tapes. point the web may be slit into two sections and one carried directly by guides 26 and 27 toa suitable folder L and the other section of the web led around turnersbars 28 28 and suitable parallel rollers before it passes to the guide or roller 27, so that the two sections of the web will be associated together before they pass to the folder. The web w is similarly led around the second and third imp res- From this lOO IIO nection with the web except thata cipher ing-in drum 12 is referred to as 120, the.

The lower carriage-frameslare connected together by a suitable-tie or yoke M, engaging hich is a crank pin 29 on the largebevel-gear 30. The carriage-frames K are similarly connected by yoke N, engaging which is a crank-pin 290, arranged on bevelgcar 300. These parts form the two driving. mechanisms. i

In the first three sheets of the drawings the driving mechanisms are shown as set quartcring, or at ninety degrees to each other, so that the two lower cylinders will be in im:' pression or printing while the two upper cyl-- inders are reversing, and vice versa, whereby the machine will run very easily and. smoothly.

in contact with said cams by springs 33. The

earns 32 are geared to turn in unison with'the" cams for the feeding-in and feeding-out loop-, ers, andby this arrangement each web will only be fed or shifted over one form-bed ata time. Thus, for example, in Fig.' 4 the web I! is stationary relatively to the lower bed B and is being shifted over the upper bed E. The looper 19 is moving upward and is giving the supply of web necessary for the movement over the upper bed. When the. cylinder F is reversing and the cylinder I printing, the looper 19 will be moving downward. This yvill cause the web to be shifted over the lower bed and the web to stand stationary over the upper bed. The same is true of the web 10 and the looper 190. The feeding-in and feeding-out drums and the feeding-in and feeding-out loopers are arranged to operate in the ordinary w'ay-that is, the-feeding-in and feeding-out drums are arranged to feed a length of web equal to two sheets for each forward and backward movement or complete reciprocation of the cylinders, and the feeding-in and feeding-out loopers are arranged to shift the-web at the proper times, which is twice for each reciprocation of the cylinders. The compensating loopers'19 and 1.90 are arranged to control an amount-0f web equal to the length of the sheet-*that is to say, the time in which the web stands statiouary and in which it is shifted being substantially the same the com pensating loopers will have a movement of one half of the sheets length, so as to control an amount of web equal to the length of the sheet; able inking-rollers O are arranged in the carriage-frames at each side of each impressioncylinder to ink the forms, and the same take' ink from fountain P. By manipulating two webs in this manner a ten, ,twe'lve, fourteen, or sixteen paged papercan be obtained.

\Vhenitisdesired to make a smaller-sized paper,..oneof the driving mechanisms, pref- :erably the upper driving mechanism, is dis-.

connected, so that only the two lower cylinders F and G will operate.

The shafts on which the bevel pinions which engage the bevel-gears 30 and 300-are arranged may be geared together, as shown in Fig. 2, by means of bevel-gears 34: and 340 and shaft 35.

Power may be applied to the .lower set 0 bevel-gears, and the upper driving mechanism may be disconnectedv by slipping the bevel-gear 340 on its shaft.

When a single web-is run through the machine, it is preferred to use what was the feeding-in device for the web to as the feeding-out device. If this is done, it is necessary to turn the shaft of the drum 120 in the opposite direction. This can be done by using a sweep 36, which carries a single intermediate 37, which can mesh. directly with the gear 38 on the shaft of the drum, and two other meshing intermediates 39 and 40, which may be shifted to transmit motion .to said gear 38, so that the same will turn in the opposite direction, as illustrated in Fig. 3. Vhen the single web is run through the machine in this manner, the same is led to the folder, as shown in full lines in Fig. 5. Another way in which the single web can be delivered out of the machine is to keep what was the feeding-out device for the web 20 in operation and lead the web 10 thereto by means of web guides or rolls 41, 42, 43, and 430, as indicated in dotted lines in Fig 5. By either of these arrangements a single web can be. perfected by the two lower'impression-cylinders and led out of the machine to form either a four, six, or eight paged paper.

--When the two lower impression-cylinders are used to perfect a single web, the single web is passed directly from the guide 17 to the impression-cylinder G by means of guide or roll 44. a

In Fig. 6 I have shown substantially the same mechanism with the two driving mechanisms set at one hundred and eighty degrees to each other. When this is done, the webcompensating device at the front end of the press is not necessary, as all the impressioncylinders will be in and out of impression at the same time. o.

The arrangement shown rn'Fig. 6.is an ex- Suit cellent form of the invention, as the two sets and hence the vibrations in the mechanism will be to a large measure counterbalanced.

In Fig. 7 I have shown substantially the.

same machine with the two driving mechanisms set to work in unison. g

a In Figs. 8 and 9 I have shown the first modified form of my invention referred to-that .is, an arrangement by which the web 10 is handled by the impression-cylinders F and G and the web w by the impression-cylin, ders H and I. In this arrangement the two webs are slit, and the sections thereof are associated and turned out sidewise or laterally of the machine by turner- bars 45 and 46 and 450 and 460, and the folder mechanism is arranged at right angles to the press.

In Figs. 10 and 11 Ihave shown the second modified form of my invention that is, the

two lower impression-cylinders are arranged to handle the web w and the two upper impression-cylinders the web w, and the two sections of each web are associated by turnerform-beds in different horizontal planes and one in advance of the other is not claimed in this case, as the same forms the subject-matter of claims in my application for patent filed January 3, 1898, Serial No. 665,358.

It is within the scope of my invention, of course,vto arrange the beds directly over each other, if desired.

-I am aware that other arrangements may be made without departing from the scope of my invention as expressed'in the claims.
