SPECIFICATIOEJ forming part. of Letters Patent No. 372,721, dated November 8, 1887.

.- .pplicaiion filed June 22,1883. Serial No. 98,901.

To aZZ whom it may concern.-

Be it known that I, STEPHEN D. TUCKER, a citizen of the United States, residing in the city of New York, county of New York, and State of New York, havcinvented certain new and useful Improvements in \Veb-Printing and Delivery Apparatus, fully described and represented in the following specification and the accompanying drawings, forming a part ofthe same.

This invention relates to that class of webperfecting printingmachines in which the forms for printing both sides ot'the web are carried upon a single cylinder, and in which the web of: er being printed upon one side is turned over and represented to the same form to be printed upon its opposite side, the travel of the web between the printing of its opposite sides being so distanced that the inside pages of the sheets upon one side will fall opposite the outside pages of the sheetsupon the other, and vice versa.

The machines of this class possess many desi rable characteristics and have gone into very extensive use, particularly in those establishments where it is desired to print directly from the type instead of from stereotype or other plates. 'Wheu, howev r, the printing is to be done directly from the type, it is necessary to make the form-cylinder of a very much larger size than when plates are to be used, as in practice'it is found impossible to successfully sccu re ordinary parallel type onto a cylinder as smallas those commonly employed when plates are used. .Vhen a cylind er of sufficient size to successfully carry the forms in type is used, it is found so large that the forms for printing both sides of an ordinary folio or four-page newspaper will occupy Very much less than its whole circumference, and this fact makes it necessary in this class of machines, when the printing is to be done directly from the type, to provide registerrolls and an increased number of impression cylinders, so that the forms will make two or more impressions upon each side of the web at each revolution of the form cylinder.

It will readily be seen that when a web is perfected by a mechanism of this character its alternate sheets or series of sheets will have (No model.)

lengthwise of the cylinder, as is usual when printing from type, the heads of their pages will be at opposite sides of the machine, and these facts make it necessary, if the sheets are to be folded,-to provide two mechanisms for that purpose which will operate to fold alternate sheets or series of sheets in opposite direetions,so as to bring the same page or pages upon the outside of all the sheets after they are folded.

One branch of the present invention relates especially to a folding delivery apparatus adapted to cooperate with a printing mechanism which prints a web in the manner above specified; and it consists in various details of construction and combinations of parts, hereinafter fully explained, by which the sheets are folded and delivered in a uniform condi tion.

There are at the present time many news paper establishments which desire to issue at different times papers of varying sizes-such, for example, as papers of four, eight, or twelve pages. To fully meet the wants of such es tablishnients it is necessary not only to produce a printing mechanism which is rapid and reliable in its operation, but to provide means by which such mechanism can be readily capacitated to produce either of the products desired.

Another branch of the invention relates more particularly to the printing mechanism; and it consists of means by which this mechanism can be operated at will to produce papers of various sizes.

In the accompanying drawings, Figure 1 is a side elevation of a printing mechanism of the character specified, provided with means by which it is capaeitated to produce papers of different sizes. Fig. 2 is a longitudinal vertical section of the so me. Fig. 3 is a side elevation of the delivery apparatus. Fig. l is a plan View of the mechanism shown in Fig. 3. Fig. 5 is an end elevation of the delivery apparatus. Fig. 6 is a transverse vertical section of the same. Figs. 7 and 8 are diagrammatic sect-ions illustrating the operation of the delivery apparatus. Fig. 9 is a plan View of the web-turner, by which the web is reversed al er being printed upon one side, so as to preditferent matter upon their upper or outersur- I sent its unprinted side to the forms. Fig. 10 faces, andifthe columns of the forms are placed l is a cross-section of the same. Figs. 11 and 12 are like views showing the same turner adjusted to a different position. Figs, 13 and 1.4 are plan views showing different means for adjusting the turner. Fig. 15 is a plan view of the delivery mechanism when operating to deliver four-page papers. Fig. 16.is a plan View of a web associating and pasting apparatus for producing a twelve-page paper. Fig. 17 is alongitudinal vertical section of the same. Fig. 18 is a side elevation'of the delivery mechanism, showing the folding-cylinders arranged parallel with instead of at right angles to the printing-cylinders. Fig. 19 is a longitudinal vertical section of the same. Fig. 20 is an end elevation of the same. Fig. 21 is a plan View of the web associating apparatusof Figs. 18,

19, and 20. Fig. 22 is a longitudinal vertical,

section of the pasting and registering devices. Fig. 23 is a detail to be hereinafter referred to. Figs. 24, 25, and 26 are diagrams showing, respectively, the order of the impressions upon the web when four, eight, and twelve page papers are produced.

Referring to Figs. 1 to 4,it will be seen that the printing mechanism shown in the present case is, as to its general construction, the same as that shown in United States Letters Patent No. 274,534, consisting, essentially, of a formcylinder, four impression-cylinders, two register-rolls, a web-turner, and suitable inking mechanism.

The form-cylinder100, which is of the usual construction and of a size sufficient to permit ordinary parallel type to be fastened to its periphery, is mounted in bearings in an appro priate frar11e-work,and is provided with means for carrying eight forms of type, which, for convenience, it will be assumed are of a suitable size to print the pages of an ordinary eight-page newspaper. These forms are arranged in two groups located diametrically opposite each other upon the cylinder, each group consisting of two pairs placed end to end with relation to the length of the cylinder, and each'pair occupying one-fourth of its circumference. These forms, it will be assumed, are placed upon the cylinder so that the columns of matter will, as is usual when printing from type, lie lengthwise of the cylinder, the heads of the columns of the groups upon the opposite sides of the cylinder pointing in opposite directions and so arranged that those for printing pages 6 3 and 8 1 will form one group with their heads pointing to the front of the machine, those for printing pages 7 2 and 5 4. the other group, with their heads to the rear, the forms for pages 6 8 and 7 5 being the advance ones of their respective groups as the cylinder revolves.

The spaces upon the cylinder between the groups of forms are occupied by inledistrlbuting tables or surfaces 101, which are supplied with ink in the usual manner, and from which the ink is taken and supplied to the forms by ordinary form-rollers, 102, operating in the same manner as in the well-known Hoe type-revolving press. i

order to print the whole surface of the web,

that each form should act twice upon each side of the web at each revolution of the cylinder. To accomplish this four impression-cylinders, 103 104 v105 106., and two register-rolls, 107 108, are provided. The web to be printed is led from a roll, 109, around a leading roll, 110, and thence to and around the first impression-cylinder, 103. After passing this cylinder it is led outward around the registerroll 107, and thence inward to and around the second impression-cylinder, 104. The register-roll 107 is placed at such a distance from the irnpression-cylinders 103 104 that the advance edge of the impression on the web given by the first group of forms against the cylinder 103 will arrive upon the cylinder 101just in time to exactly join with the rear edge of the impression given by the same group of forms against that cylinder. From this itresults that the first group of forms makes two impressions upon the web in succession, the second impression being just in advance of the first.

Following the rear edge of the impression made by the first group of forms against the cylinder 103 will be a blank space equal to the space upon the formcylinder between the groups of forms. At the end of this space the second group of forms will make an impression upon the web against the cylinder 103, and passing to the cylinder 101 will make asecond impression just in advance of the first, which second impression will just join the impression given by the first group of forms upon the cylinder 103,'and thus fill the blank space referred to. This operation being repeated at each revolution of the form-cylinder, one side of the web will be wholly covered, the pages for each side of the sheet occurring twice in succession, as e, 4f, i 4}, 850., as shown in Fig. 25. After passing the impression-cylinder 101 the web, now printed upon one side, is conducted around a leadingroll, 111, thence around a web-turner, by which it is reversed, so as to present its unprinted side to the forms, and thence around the leading-rolls 112 113 to and around the impression-cylinder 105. From this cylinder the web passes outward around the registerroll 108, and thence inward to and around the last impression-cylinder, 106. The operation of the form-cylinder in connection with the impression-cylinders 105 106 to print the side of the web now presented is exactly the same as already describedin connection with the cylinders 103 101.

The distance traveled by the web between the cylinders 101 105 will be so regulated by the position of the rolls 111 112 113, one or more of which may be adjustable, that the impressions upon the opposite sides of the web will be in perfect register, and that the pages for the insides of the sheets will be backed by IIO the pages for the outsides of the sheets, and vice versa. I

The printing mechanism just described may be provided with tapes, as 111, arranged as shown and described in my application for Letters Patent filed in the United States Patent Office April 27,1882, Serial No. 59,717, and it will also be provided with forwarding-rolls, as 115, operating in connection with the registerrolls in the manner set forth in the Letters Patent hereinbefore referred to.

Motion is communicated to the above-described mechanism by the driving-shaft 117 through the gear 116, tixed thereon, and which engages with the gear 170 on the form-cylinder shaft, this gear in turn driving the impression-cylindcrs 103 101 105 106 through their respective gears 171 172 173 174, as shown in Figs. 1 and 2.

The forms, as before stated, are so placed upon the cylinderlOO that those for printingone side of the sheets will be headed in one direction and those for the otherside of the sheets in the opposite direction, so that the heads of the pages in register upon the opposite sides of the web will point in the same direction, and whereby, also, two succeeding sheets will have their heads toward one side of the machine and the next two toward the opposite side of the machine, as shown in Figs. 21, 25, and 26. After leaving the last impressioncyiinder the printed web passes beneath a roll, 118, when it is split upon the line [ttt' (see Fig. 25) by a slitter, 119, so as to pass forward in two sections. From the roll 118 the two sections of the web are led around turning-bars 120 121, so arranged, as shown in Fig. 4, that the sections are turned at right angles to their previous path of travel and brought directly one above the other. The sections thus associated then pass beneath the roll 122 and between the cutting-cylinders 128 124, by which they are partially severed upon the lines a z.

in order to secure the proper register between the sheets of the two sections of the web after they are associated by passing around the bars 120 121, the section which passes around the bar 121 is, after being split from its companion, caused to take a longer path of travel before reaching its turning-bar.

. This is effected by means of register-rolls, as

125 126 127, arranged as shown in Figs. 3 and 1, the section passing beneath roll 125, upward around roll 126, and thence returning bcneath roll 127. The roll 126 may be made adjustable, as shown, so as to vary the distance traveled by this section of the web as may be desired.

If it is desired to unite the two sheets which go to make up the complete product, it may be done by means of a paster, 128, arranged, as shown in Fig. 3, to apply lines of paste at the proper points as the section of the web passes around the roll 127;

The cutting-cylinders 123 1251, which are of the same size as the impression-cylinders, are connected by gears 176, and made to run in unison therewith by means of the train of gears 177 178 179 180, bevel-gears 181 182, and gears 183 184, the gear 184. being of double width, so as to engage with both the gears 183 176. The gear 177 drives the roll 118, while the gear 178, through thegear 186, drives the registering-roll 108. The gear is fixed on the shaft 187, carrying the revolving pastingblade, and drives the register-roll 127 and paste-fountain roll 188 through their respective gears 189 190. The bevel and spur gears 182 183 are secured together and run loose on a stud, 191.

The associated sections of the web, after be ing partially severed by the cutting-cylinders 123 121, pass into the bite of the series of accelerated tapes 2 3, which complete the severance of the sheets from the web' and deliver them to the. folding mechanism. This mechanism consists, primarily, of the folding-cylinders 129 130, mounted side by side and slightly separated, and which, as here shown, are arranged to give two parallel folds to the sheets. 'Thcsc cylinders are driven turn for turn with the cutting'cylinders by the gear 181 through the train of gears 192 1.93, the lat.- ter being fixed to the shaft of the cylinder 130. These cylinders are of slightly greater diameter than the cutting-cylinders, and'are connected, so as to run in unison, by thegears 191 195, and these gears also drive the two series of tapc-pulleys 16 17 through their respective gears 196 197, and thus give to the two series of tapes 2 3, that serve to convey the sheets from the cutting to the folding cylinders, a slightly'accelerated speed. The series of tapes 2 pass around pulleys l4, thence around pulleys 21, theme around pulleys 16, and above pulleys 1S, returning around pulleys 20. The series 3 pass around pulleys 15, thence around pulleys 21, thence between pulleys 16 and 17, returning over pulleys 19.

It will readily be understood that in folding newspapers it is very desirable, no matter how many folds are made in the sheet, that the title or heading on the first page should always be left in sight. Itis obvious, therefore, from an inspection of Fig. 25, which represents the web as it issues from the printing-machine, that to accomplish this two succeeding pairs of sheets must be folded in one direction and the next two pairs in the opposite direction. To effect this the sheets, as they emerge from between the pulleys 1.6 17, pass into the control of an oscillating guide, 22, which is oper atcd so as to direct two successive sheets alternately to each of the pair of foldingcylitr dcrs 129 130, which cylinders are so operated as to told their respective sheets in opposite directions.

The oscillation of the guide 22 is effected by means of an arm, 23, secured to the outer end of the, shaft upon which said guide is mounted and to which is attached a rod, 21,.(see Fig. 6,) carrying a stud, 25, which lies in the groove of a cam, 26, secured to a gear, 27, which engages with a gear, 28, of one-fourth
