LOUIS IV. SOUTHGATE, OF WVORCESTER, MASSACHUSETTS, ASSIGNOR TO THE CAMPBELL PRINTING PRESS AND MANUFACTURING COMPANY, OF NEW YORK.
PRINTING-PRESS.
SPECIFICATION forming part of Letters Patent No. 471,403, dated March 22, 1892.
Application filed August 17, 1891. Serial No. 402,947. (No model.)
To all whom it may concern.-
Be it known that I, LOUIS W. SOUTHGATE, a citizen of the United States, residing at Vorcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Printing-Presses, of which the following is a specification.
The aim of this invention is to double the capacity of the ordinary web-press, and, furro ther, to assemble the products so that a four, six, or eight page paper or any addition or multiple thereof may be printed and folded in a machine of single width.
To this end the invention consists of the device described and claimed in this specification and illustrated in the accompanying drawings, in which- Figure 1 is a diagram illustrating the printing-machine and the folding-machine and how the webs are passed through the same. Figs.
2 and 3 are end elevations of the double folding-machine. Fig. 4 is a plan of the webturner. Figs. 5, 6, and 7 are a plan, a sectional plan, and a side elevation, respectively,
2 5 of what 1 term the web-reverser, on an enlarged scale. Figs. 8, 9, and 10 are aside elevati'on, a plan, and an end elevation showing the manner in which the parallel cylinders of the turner and of the reverser are mounted.
Figs. 11, 12,,and 13 are diagrams showing the arrangement of plates and illustrating the way in which an eight, siX, and four page paper, respectively, is printed and folded; and Fig. 14 represents a modification of part of the mechanism of the double folder.
Referring to the said drawings, A and B represent two type-cylinders geared to run in opposite directions. These type-cylinders are preferably made so as to carry four plates,
and the plates are preferably so arranged that the columns will be parallel to the travel of the web.
Mounted to bear against the type-cylinders, preferably vertically above and below the same, are the impression-cylinders C and D,
bearing on type-cylinder A, and the impression-cylinders E and F, bearing on type-cylinder B.
Suitable inking devices G are arranged, as
shown, at each side of each type-cylinder, so
that the type-cylinders will be properly inked, so as to print where the same come into contact with the impression-cylinders.
Two rolls of paper H and I are mounted at one end of the machine, so that the two webs may be drawn from the same over suitable guide-rollers I I between the cylinders D and A. From here the double web passes around guide-roll 2, around cylinder F, between cylinder F and B, around guide-roll 3 to what I term a reverser, and which will be described at length further on. From the reverser the double web runs around guiderolls 4:, 5, and 6, around cylinder C, and between the latter and cylinder A. From the cylinder C the webs are separated, one going under the roll 7 and the other going through a web-turner, over roll 9, and then to roll 8, where the webs reunite. From the roll 8 the double web passes around cylinder E and thus in contact with cylinder B, then around a guide-roll 10, and then between the cutting or perforating cylinders J and K. From the cylinders J and K the double web is carried by the belt 11, running around belt-pulleys 12, 13, and 1a and by the belt 15, running around pulleys 16 and 17, to between the cylinders 18 and 19. These cylinders 18 and 19 run at increased peripheral speed relatively to the mechanism before described, and therefore the'sheets will be separated from the web in the usual manner.
Mounted below the cylinders 18 and 19 is a switch 20 of any of the usual constructions, and the sameis arranged to switch the sheets alternately to each of the folders, or rather to the double folder now described. Each folder consists of the former L and M, and these formers L and M are oppositely set or arranged with their backs to each other. stances, of course, the equivalent inclined double roll maybe used in place of theformers. From the switch 20 the sheets are carried by the usual tapes (not shown) alternately down over the formers L and M and then between 5 the presser cylinders or rollers 21 21. From the cylinders 21 21 the sheets pass through the cutting-cylinders 61, 62, 63, and 64;, which maybe used in connection with a four-page paper, and the operation of which will be de- :0:
In some in- 0 scribed further on, to the folding-cylinders 22, 23, 24, and 25. The cylinder23 tucks the sheets into the cylinder 22 in the usual manner to make the second fold,and the cylinder 2 Ltucks the sheets in the same manner into the cylinder25. Thus the sheets are twice folded. If it is desired to further fold the sheets, the fold- 1n g rollers and tuckers may be arranged below the previously-describedfolding-cylinders in the usual manner, and as indicated in dotted lines in Fig. 1; but in modern newspaper work two folds are generally sufficient.
In most instances it is desirable to deliver all the folded sheets on the same side of the machine, and, as shown in Figs. 2 and 3, this may be readily done. The fold ed sheets from the cylinder 25 are carried by belt 26, passing around pulleys 27, 28, and 30, and by belt 29, passing around pulleys 30 and 31, and deposited in the receiver 32. The sheets from the cylinder 22 are carried by belt 33, running around pulleys 34, 35, 36, and 37, and by belt 38, running around pulleys 51, 35, 36, 52, and 53, and deposited in the receiver 39. These receivers, as shown, are arranged on the same side of the machine. The details of the formers L and M and of the folding-cylinders 22, 23, 24, and 25 are not shown, as the same per se form no part of the invention, and as the same are of the ordinary construction well understood. Thus this double folding-machine will fold sheets delivered to it in opposite ways, and, as hereinafter described, this is the way the sheets are printed. The disposition of the folding and cutting cylinders on four shafts is very advantageous in that it saves gearing.
The re verse r will now be described, the web from roll lI being designated by a and that from roll Iby b. The web I) is turned back over roll 4 and then is passed over the top of the forly-five-degree turner bar or roll 40, then around the parallel cylinder N, then back and up over theforty-five-degreeturner-bar ll, and thus under the web a. The turner-bars in the reverserare preferably arranged in the same vertical plane, one above the other, as shown. This doesnot turn the web I), but simply reverses the webs, placing web 5 on the opposite side of the Web a as the turner-bars 40 and 41 are parallel. The turner (see Fig. 4) is of the ordinary construction, and may be arranged between cylinders O and E or at any convenient point, so as to turn web I after the same is printed on both sides. The
turner consists of the oppositely-disposed forty-five-degree turner-bars 42 and 43and the parallel cylinder N The parallel cylinder N and N of both the reverser and the turner are mounted in the brackets 44, which are horizontally adjustable on brackets 45, which latter are vertically adjustable on the press-frame. Thus the rolls N and N 2 may be accurately adjusted, so that the web I) will properly run on the turner-rolls and so that when the web I) again joins the web a that the web I) will be in proper register with web a.
The operation will now be described, it being first noted that when the webs come the second time into contact with the type-cylinders that the second set of plates on the typecylinders will print on the webs over the pages that have been previously printed by the first set of plates, and vice versa; also, it may be noted that the rolls 2, 5, and 8 are vertically adjustable, so as to secure proper register-between the various impression-cylinders.
The operation of printing and folding eightpage papers will first be described, and reference, so as to follow this description, should be had to Figs. 1 and 11. position of the plates on the type-cylinders is shown developed into plan, and the left-hand column shows the pages or the part of the webs first printed by the type-cylinders and the right-hand column shows the pages last printed from each type-cylinder, and at the bottom is indicated the Way each double sheet is folded. The double web from the rolls first passes around impression-cylinder D and 111 contact with the type-cylinderA, where pages 2 7 and 6 3 are printed on web a, then around impression-cylinder F in contact with typecylinder B, where pages 5 at and l 8 are printed on web I); then the webs are reversed by the reverser, or the web 1) is placed undertheweb a as the webs are then moving, thus bringing the printed surface of each web together or opposed to each other; then the double web passes around the impression-cylinder O and thus in contact with the type-cylinder A, Where web I) is printed upon the opposite side to that previously printed by cylinder B, and pages 6 3 and 2 7 are printed; then the web I) is turned over by the turner; then both Webs pass aroundcylinder E and thus in contact with type-cylinder B, where pages 1 8 and 5 l are printed on web a. The special location of the turner is thus seen to be immaterial so far as eii'ecting the result is concerned, as the same may be arranged at any point in the travel of the webs beyond cylinder 0. Thus two oppositely-disposed eight-page papers are printed at each revolution of the type-cylinders. The double web thus printed is carried to the cutting or perforating cylinders J and K and then to cylinders 18 and 19, where the double sheets are pulled from the double web and switched into the reverselyarranged double folder previously described, where each double sheet is folded so that the heading comes outside.
For a sixpage paper the plates are arranged as shown in Fig. ]2-that is, with two diametrically abreast and one plate behindandthe web I) used in this instance is only one-ha1f width. This is easily accomplished by using a half-roll in place of the roll H of full width. The operation with this web and half-width web is exactly the same as before described in connection with the eight-page paper, and results in two products of six pages each folded and disposed,as shown in Fig. 12. It may be noted in connection with the six- In Fig. ll the dispage paper that when the half-web passes over the turner that the half-web will be laterally transposed from one side of the machine to the other, as indicated in the diagram, and as is readily understood as the turner-bars of the turner are oppositely disposed.
hen a four-page product is desired, the folder mechanism is run at a slightly slower speed than that previouslydescribed through a suitable change-gearin g, (not shown,) so that the peripheral speed of the cylinders 18 and 19 is not accelerated. The serrated knife or set of cutters is removed from the cylinder J, or the cylinders J andK are opened or spread apart, so that the webs may freely pass between the same, and knives are inserted in cylinders 62 and 63, so that the cylinders 61, 62, 63, and 64 will act as cutting -cylinders. The switch 20 is disconnected and one web is carried down over former L and the other over former M, from whence the sheets are cut off and folded in the usual manner. During this operation the cylinders J, K, 18, and 19 act simply as guides for the two webs.
In some instances I contemplate omitting the cutting-cylinders 61 62 63 64 and putting the knives on the folding-cylinders, as at 66 and 67 on cylinders 24 and 25.
The way the double web for the four-page sheets is printed is shown in Fig. 13, and as the operation is the same as described in connection with the eight-page sheets the operation of printing four-page papers will not be described at length; but itmay be noted that all the sheets cut from the web I? are folded one way and all those out from web a the other. Thus four four-page papers are printed at each revolution of the type-cylinders.
In some instances the turning of the web 1) between impression-cylinders O and E may be omitted while printing four-page papers, so that the product will be webs similarly printed; but it is generally desirable to turn web I) in all instances, because then the printing-machine can once be set in proper register, and then the machine does not have to be touched, no matter whether a four, six, or eight page paper is to be printed, so far as register is concerned, and the folding can be conveniently done, as before described.
In some instances it may be desired to print only on one web. This can benicely done by running one web, as a, from-the roll I first around guide-roll 2, (see dotted lines, Fig. 1,) then over rolls 4, 5, and 6, impression-cylinder 0, in contact with type-cylinder A, where one side is printed, then over guide-rolls 7 and 8, around impression-cylinder E, in contact with type-cylinder B, where the other side is printed, thus acting as an ordinary single-Web press.
A four-page paper could also be printed by running a web, as a, around impression-cylinder D, in contact with typecylinder A, around rolls 2, 4, and 5, up around the roll 8, and around cylinder E, thus perfecting against type-cylinder B; but the first operation is preferred, because the impression'cylinders O and E are set in register in the operations of printing six and eight page papers. Of course While printing a single web two of theinking apparatuses are thrown out by being moved.
. away from the type-cylinders in the usual manner; also, in the first operation the-impression-cylinders D and F are thrown out by being moved away from the type-cylinders, and in the second operation the impressioncylinders O and F are thrown out. It will also be seen that during these operations that the web does not touch either the reverser or the turner. The product thus formed may all be printed in one way and directed to one folding-machine if the latter is set, as before described, for a four-page paper, or the product may consist of oppositelydisposed papers when the same would be cut from the web and alternately switched into each folding-machine, as described, in connection with printing eight-page papers; The disposition of the plates, in case only one web is printed, is so well understood that it is not thought necessary to describe the same; but it may be noted that if the double folder is to be used the plates must be set so that the product will be a web having the papers alternately oppositely disposed on the same. Thus a compact printing and folding machine is provided which has twice the speed of the ordinary web-printing press. Further, my improved machine will print one or two Webs, as desired, the full or part width of the type-cylinders, and in case two webs are printed the same may be assembled or associated together to make a six or eight page paper.
It also will be seen that any multiple or addition of four, six, or eight may be printed by simply running the press two or more times, as may be necessary. Thus the machine has great speed range, and can be quickly started, as in the case of a six or eight page paper only a single set of plates is used.
The relative position of the parts and the disposition of the plates on the type-cylinders may be varied without departing from the principles of my invention.
Modifications of the construction may be made by the mechanic skilled in printingpress machinery without departing from the scope of my invention.
Having thus fully described my invention, What I claim, and desire to secure by Letters Patent,is
