SPECIFICATION forming part of Letters Patent N o. 648,938, dated May 8, 1900.

' ippnmionneaNovemtefzs,1899. stanno. 737,989. memorial.)

To all whom it may concern:

Be it known that I, JOSEPH L. FIRM, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Printing-Presses, of which the following is a specification.

The principal object of my invention is to provide a new and improved printing-press which is adapted to print a plurality of copies of a newspaper or pamphlet on continuous webs and to assemble the webs belonging to the respective newspapers or pamphlets in an expeditious manner by a less number of forms or plates than heretofore used. Y

Another object of my invention is to economize space and construction by having less form and impression cylinders where a plurality of webs are used, making a machine more compact in form and less liable to get out of order in operation.

Many of the parts of my improved press are substantially similar to presses heretofore in use, and it will therefore be necessary for me to show and describe only such parts as are necessary for understanding novel features.

Figure l of the accompanying drawings is a vertical longitudinal section at right angles with the axes of the printing-cylinders. Fig. 2 is a plan view of the press. Fig. 3 shows the position in which the pages are printed, from one to eight, inclusive, on the webs C and D of Fig. l. Fig. 4 shows the manner of turning a portion of the webA laterally onto another portion of the same web. Fig.- 5 shows the arrangement of forms on certain of the form-cylinders. Fig. 6 shows in edge view the position of the pages in signatures containing,respectively,six,eight,ten,twelve, fourteen, and sixteen pages. Fig. 7 shows the same in isometrical view. Fig. S is a modified arrangement of the printing-cylinders. Fig. 9 is a detail of the mounting of an inking-cylinder in end view. Fig. 10 is a side View of the same. Fig. 11 is a modification of Fig. 1.

The form and impression cylinders, the inking-rolls, and the web-holding rolls are all mounted with their axes parallel upon the frame 200. The location of these.rolls and the positions of the guide-rolls will best be explained by describing the path of each web through the machine.

The supply-rolls of webs A and B are located one above the other at one end of the printing mechanisms. the webs C and D are located one above the other at the opposite end of the printing mechanisms. The folding mechanism a ot for the webs A and B is located at the end of the machine outside of the supply-rolls for those webs. The folding mechanism b c for the webs C and D is located at the opposite end of the machine 'and outside of the supply-rolls of the webs C and D. VThus the printing mech.

anisms are grouped at the middle of the machine, and at each end thereof are placed two Web-supplying rolls and the mechanism for folding the'same after printing.

Each web for the purpose-of being printed proceeds from its supply-roll toward the middie of the machine, the webs of one end proceeding inversely to those at the opposite end. After being printed each web returns toward the end of the machine from which it started and proceeds past its supply-roll to the folding mechanism located behind its supply-roll at that end.

The printing mechanisms for the several Webs are arranged so that the pair of printing mechanisms for the two upper webs coming from opposite ends of the machine occupy corresponding positions horizontally and the pair'of print-ing mechanisms for the lower webs coming from opposite ends of the machine occupy corresponding positions beneath the first pair. One form-cylinder, as H, is made to serve in both the printing mechanisms of the first pair and another form-cylinder, as L, is made to serve in both printing mechanisms of the second pair., The formcylinders F and H print upon the web Aand the form-cylinders O and H print upon the web C. Similarly-they form-cylinders J and L print upon the web -B and the form-cylinders R and L print upon the web D. The two central form-cylinders H and L' may receive ink from different or from the same inking mechanism interposed between them, as shown, respectively, in Figs. l and l1, as well as from additional inking mechanisms lo- The supply-rolls of IOO R are provided with corresponding inking' mechanisms consisting of the cylinders e, 7e, j, and Z, with their cooperating rollers e' to es, inclusive, 7c' to ks, inclusive, j to 7'8, inclusive, and Z to Z8, inclusive.

The web A passes over the rollers 1 and 2 and to about the impression-cylinder E and is printed upon one side by the form-cylinder F. It4 then passes about the impression-cylinder G and is printed on its opposite side by the form-cylinder II. It then passes over the guide-roller 3, under roller 4f, where it is acted upon by the slitter 101 to separate such sections of the web as is necessary, and then past the bars 15 and 16, by which any section of the webs may be imposed upon another, if desired. It then passes over the roller 5, where the sections of the web may be further divided by the slitter 104, and then between rollers 6 and 7 to the folding mechanism @and a The web C has a similar course over rollers 2l and 22, beneath rollers 23, about impression-cylinders M and N,wh ereit is printed "by the form-cylinders H and O, over guiderollers' 24 25, where it may be slit by the slitters 102, over roller 2G and bars 17 and 1S, if desired,to impose one section upon another, between rollers 27 and 2S, and then over rollers 13, Where it is engaged by the slitter 44C, and thence between rollers 3S, 39, 40, and 4l to the folding mechanism.

The web from roll B passes over roller S, under roller 9, about impression-cylinders I and K, where it is successively acted upon by form-cylinders J and L to print opposite sides, then under roller 10, over roller 11, Where it is acted upon by slitter 100, if desired, past bars 13 14, by which one section may be imposed upon another, over roller 12, between rollers 6 and 7, where it is associated with the web A and acted upon by slitters 105, and then to the folding mechanism d and d.

The web D passes over rollers 30 and 3l, about impression-cylinders P and Q, where it is acted upon by form-cylinders L and R to print both sides, about rollers 32 and 33, where one or more of the sections are severed by the slitter 103, if desired, past the bars 19 and 20, by which one section maybe imposed upon another,` over roller 34, under roller 35, between rollers 27 and 28, where it is associated with the web C, and thence to the folding mechanism b and c.

In Figs. 8 and l1 the general course is the same, the differences consisting, mainly, in shifting the relative position of some of the impression and inlring cylinders. In Fig. 8 two of the im pression-cylinders N and D are located outside of the form-cylinders O and R', and their inking-cylinders k and Z are placed beneath these form-cylinders.

In Fig. 11 the outer form-cylinders I, F, O, and R are made of half the size of the formcylinders H and L, and a common inking-cylinder g is used for the form-cylinders H and L.

The form-cylinders I-I and L each print upon two 'different webs at a time-the cylinder II upon the webs A and C and the cylinder L upon the webs B and D-thus saving many plates and forms, the number depending upon the number of different papers being printed. Vhere eightl copies of eight-page papers are being printed at each revolution, sixty-four different forms would ordinarily be required, whereas by the arrangement herein shown, the central form-cylinders being used for all papers, one-quarter of the above number of forms, or sixteen, vare saved, necessitating only forty-eight instead of sixty-four. The same is true when printing four copies of sixteen-page papers.

In printing eight-page papers four full- Width webs are used, which are slit on their central line and each folded longitudinally.

In printing a larger paper one or more of the sections of the web alongside the central line is slit clear of the body of the web and turned over bars, as 15 16, upon the section on the other side of the central line and is folded with it and its attached outer section.

In case ten, twelve, or fourteen page papers are being printed certain of the webs are either half or three-quarters width, and one section is slit from the others and turned over upon them, as shown in Fig. a. For ten-page papers two half-width'webs and two three quarterwidth webs are used. For twelve-page papers two half-width webs and two full-width webs are used, the full-width webs being slit centrally and the two halves su perposed by the bars, as 15 16, before reaching the folders. For fourteen-page papers tWo full-width webs and two three-quarterwidth webs are used, and for sixteen-page papers fourfull-width webs are used, the Webs in both cases being slit on the center line of the machine and the parts superposed, as described, before reaching the folders. In each case one-.quarter of the usual number of plates is saved.

In Figs. 9 and 10 theinl ing mechanism is shown mounted so that it may be moved to one side to facilitate putting the plates upon the cylinders H and L. The inking mechanism is mounted upon a frame which slides upon guides on the main frame 200 and carries a shaft 304:, which has pinions 302 302 thereon engaging racks 301 301 on the main frame, the shaft having a crank 303 attachable to one end thereof.
