SPECIFICATION forming part of Letters Patent No. 631,424, dated August 22, 1899.

Antietam filed March 28, 1392. smart. 426,749. on moan.)

To aZZ whom itmay concern:

Be it known that I, JOSEPH L. FIRM, a citizen of the United States, residing in Jersey City, in the county of Hudson and State of New Jersey, have invented certai and useful Improvements in Printing-Presses, of

which thefollowing is a specification, reference being had to the accompanying drawings, in which 7 Figure I is a central longitudinal vertical section ofaa printing-press and-folder, the

folder being in elevation. Fig. 11 is a top or plan view of the press and folder. Fig. III

is an end elevation of a press, showing double formers and folding-rollers,the folding-rollers being in section. Fig. IV is an end elevation of the arrangement exhibited in Fig.VII,showing the formers and folding-rollers, the folding-rollers being in section. Fig. V is a side elevation of the folding-blades and the mechanism for operating them. Fig. VI is a top or planview of the same.

them arranged to deliver printed sheets into a common folder. Fig. VIII is a side elevation of the-inside of one of the formers. Fig. IX is a top or plan view of the same. Fig. X is a side elevation of a part of the mechanism for shifting the webs laterally. Fig. XI is a section on line -XI XI of Fig. III, showing the arrangement of the roller. Figs. XII to XXIII are views showing-the arrangement of the forms on the form-cylinders for printing copies of a newspaper or pamphlet on continuous webs and to gather or assemble the sheets belonging to the respe tive newspapers in an expeditious manner without wholly turning or reversingthat is, without turning the web over or reversing the direction of its travel only partof the webbeing turned overin pass- Fig. VII is a top. or plan view of two printing-presses, showing in Fig. .11.

ing over the longitudinal folders and between the tapes which convey the sheets to the foldns-ros.

Another object of my. invention is to provide new and improved means for folding the sheets of the newspapers or pamphlets.

. 7 Other objects of my invention are to pro vide a new and improved slitter for slitting the web or webs longitudinally, to provide a new and improved folding-blade for folding the sheets, and to improve the construction and operation of printing-presses in general. I accomplish these objects as hereinafter specified andas illustrated in the drawings.

That which I regard as new will be pointed outin the claims.

.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 describe only such parts as are new.

I In the drawings, 1 indicates the printingpress, which is providedwith two sets of form and impression cylinders and is adapted to print from two rolls of paper. For printing newspapers the press may be arranged as shown in Figs. I and II, where it may be of the width of two sheets of the newspaper and be provided with a single former, as indicated in full lines in Figs. I and II, or it may be of the width of four sheets and provided with a double former, as indicated by dotted lines Instead of using a single press, as shown in Fig. II, two presses 2 and 3 may be used, each provided with a single former and provided with a single folding mechanism 4, as shown in Fig. VII. In this construction the presses are usually each of the width of two sheets of the newspaper when it is desired to print one paper of thirty-two pages;

but by making each press of the width of four sheets two papers of thirty'two pages each or one of sixty-four pages may be printed.

The different arrangements of the presses and folding apparatus will be described severally.

Referring to the form of press shown in Figs.I and II, in which a single press is used .provided with a single former, 5 and 6 indicate rolls of paper,which are suitably mounted over the press, as indicated by dotted lines in Fig.1. v

7 and 8 indicate impression-cylinders, and 9 and I0 form-cylinders, of one part of the press, and 11 and 12 indicate theimpressioncylinders of another part of the press, and 13 and 14 the form-cylinders of the'second part of the press. The several form-cylinders are inked from ink- fountains 15, 16, and 17 by suitable ink drums and rollers, which need not be particularly described, as they are similar to those in common use.

18 indicates the web from the roll 5, which web passes from the roll around a roller 19 between the impression and form cylinders 7 and 9, where it receives its first impression, around the impression-cylinder 7, up between the impression- cylinders 7 and 8, and thence between the impression-cylinders S and the form-cylinder 10, where it receives its second impression, downward between rollers 20 and 21, thence between rollers 22 and 23 to a former 24. The former 24 is of the usual V- shaped form, in some respects similar to that described in my application for Letters Patent of the United States, Serial No. 329,766, heretofore filed by me. The web 18 passes upward around the former 24, by which it is folded longitudinally, the folded edge coming in contact with a wire 25, which is placed at the apex of the former 24. One end of the wire 25 is connected to the frame 26 of the press, and the other end is connected at a suitable point to the former 24, as indicated by dotted lines in Fig. I, and, as shown in Fig. XXV, the wire passing through a slot in the apex of the former. The former 24 is pivotally connected at its lower end in the frame of the press, as shown in Fig. I.

27 indicates a rod which is pivotally mounted upon a shaft 28, secured in the frame of the press, as shown in Fig. I. The rod 27 is provided with an arm 29, which is connected by a spring 30 to a cross-bar 31, or any other suitable device, secured to the frame of the press. The tension of the spring 30 is such as to exert an upward pressure on the arm 29, thereby throwing the upperend of the rod 27 outward. The upper end of the rod 27 projects into the,slot in the apex of the former and engages the underside of the paper as it passes over the former. By this construction the paper is held taut and is thetefore slit more readily by the slitting-wire. \Vrinkling of the paper is also prevented by this means, and the folding of the paper is consequently made tnneh easier.

32 and 33 indicate rods connected by a turnbuckle 34, as shown in Figs. I, XXIV, and XXV, the rod 33 being connected to the frame of the press in such a manner as to project horizontally toward the former 24, to which it is connected. The rods 32 and 33 serve to support the former in its proper position. By adjusting the turnbuckle 34 the length of the rods may be regulated, thereby adjusting the angle of the former and the tension of the slitting-wire. The slitting-wire also serves to prevent wrinkling of the paper. 35

indicates a similar turnbuckle connected to rods 36 and 37, substantially similar to rods 32 and 33 and similarly mounted near the lower part of the former 24. The movement of the slitting-wire 25 eifected by the adjustment of the former 24 is sufiicient to vary the tension of the wire, although this movement is not very great. The lowerend of the wire is secured to the former ashort distance from its apex, and the wire bears upon the former in a slot in the apex, so that by this arrangement any movement of the upper end of the former will affect the tension of the wire.

38 indicates bars which extend transversely across the frame of the press at the upper end of the i'ormer 24, to which they are connected and serve as guides for the paper as it passes around the former. From the former-24 the slit webs pass upward between the cuttingcylinders 39 and 40, which cut the web transversely at every other transverse margin into sheets. The webs then pass through suitable rollers 41 42 43 44 and tapes to foldingblades 45 and 46, located overfolding- rollers 47 and 48. The folding-blades 45 and 46 serve to force the sheets between the folding- rollers 47 and 43, which fold them. If it is desired to make more than a quarterfold, other rollers and folding-blades may be provided. The operation herein described is illustrated in the right half of Fig. III, a single former only being used and one set of cutting and folding rollers.

The folding-blades 45 and 46 are carried by arms 49 and 50 and 51 and 52, respectively, as best shown in Fig. VI. The arms 49 and 50 are mounted upon a rock-shaft 53, suitably mounted in a frame 54, and the arms 51 and 52 are mounted upon a rock-shaft 55, mounted on the opposite side of the same frame.

56, 57, 58, and 59 indicate arms mounted upon the outer ends of the shafts 53 and 55, each of which arms carries a curved rack 60, adapted to inter-mesh with a spur-gear 61, mounted upon a shaft 62, which shafts are mounted in suitable bearingsin the frame 54, as best shown in Fig. VI. Two of the arms, as 56 and 57, are connected by connectingrods 63 to suitable driving mechanism adapted to reciprocate said connecting-rods and thereby reciprocate the shaft upon which said arms are carried. By this construction when the connecting-rods 63 are reciprocated the shaft 53 will be rocked, thereby causing a partial rotation of the gears 61 alternately in opposite directions,thereby causinga rocking of the shaft similar to the rocking of the shaft 53, but in the opposite direction. The folding-blades 45 and 46, carried by the arms 49 and 50 and 51 and 52, will thereby be alternately reciprocated. By this construction as the sheets pass under the foldingblades they will be struck by the descending blades and forced between the.rolle'rs 47 and 48. By this construction a much more rapid folding is eifected than by any other con- ,st-ruction known to me, as twice as many ICO folds may be made as by the use of a single reciprocating blade operated at the same speed.

In order to provide for the mounting of the blades 45 and 46 so that they will fit accurately between the rollers 47 and 48 and will not interfere with each other, they are mounted - up0n racks 64 and 65 the teeth of which are so arranged as to intermesh with each other, and they are thereby enabled to pass each other.

66 indicates the web from the roll 6, which web passes from said roll under a roller 67 and between the form-cylinder 13 and impression-cylinder 11, where it receives an impression on one side, and thence upward between the impression- cylinders 11 and 12 and between the form-cylinder l4 and impressioncylinder 12, and thence downward under a roller 68 between pasting-rollers 69 and 70, and thence between the rollers and 21, where it passes under the web 18 from the roll 5. It thence passes through the press in the same manner as described for the web 18, being associated with said web. If it is desired to print a six-page paper, instead of associating the webs 18 and 66, as above described, they may be passed through separate folding mechanism and folded separately.

When the press used is of double width, or the width of four pages, instead of a single former 24 double formers 71 and 72 are used, which are mounted substantiallyin the same way that the former 24 is mounted and are substantially similar in construction. Instead of a continuous roller 23, however, at the lower end of the former two rollers 73 and 74 are used, which are mounted upon the same shaft 75, as best shown in Fig. III. The rollers 73 and 74 are crowned, as shown in Fig. XI, and are adapted to be moved toward or from each other upon the shaft, moving upon a feather 76, as shown in Fig. XI. The rollers 73 and 74 are operated by means of levers 77 and 78, which are mounted upon suitable standards 79 and 80, connected to the frame of the press in any suitable manner. Each of the standards 79 80 is provided with a slot 81, in which is mounted a hand-wheel 82. The hand-wheels 82 are each mounted upon a cross-bar 83, which extends through suitable bearings in the standards 79 and 80, and are screw-threaded,as shown in Fig. III. One end of each rod 83 is connected to the adjacent lever 77 01-78. The construction is such that by rotating the hand-wheels 82 they will operate on the screw-threads of the rods 83,

thereby moving the rods 83 back or forth, and consequently operating the levers 77 and 78. The lower ends of the levers 77 and 78 are fitted into grooves 84 and 85, formed in the ends of the rollers 73 and 74, so that therollers will be permitted to rotate independently of the levers 77 and 78. By this construction the rollers 73, and 74 may be moved to or from each other, as desired. When the formers, 71 and 72 are used, the roller 20, instead of being an ordinary roller, is provided with a slitter adapted to slit the web longitudinally on a central line. By this construction the broad web as it comes from the form and impression cylinders will be slit before it reaches the formers 71 and 72, where it will be separated, and the separate Webs may afterward be folded separately or together, as will be hereinafter described.

By shifting the rollers 73 and 74 the webs may be moved laterally and their edges made to register with the edges of the formers, or the webs may be properly shifted upon the formers. Then folded separately, they may pass through any suitable folding mechanism, preferably one web passing through that hereinbefore described in connection with the single former and the other through similar cutting and folding mechanism, as shown in Fig. III, wherein 86 and 87 indicate cuttingcylinders which are substantially similar to the cutting- cylinders 39 and 40 and serve to cut the web transversely at every other trans verse margin int-o sheets.

88 89 and 90 91 indicate guide-rollers for carrying the sheets from the cutting-cylinders to the folding mechanism, which rollers carry suitable tapes, as shown in Fig. III.

92 and 93 indicate folding-rollers substantially similar to the folding- rollers 47 and 48.

The sheets are forced between the folding rollers by means of folding-blades 94 and 95, which are substantially similar to the folding-blades 45 and 46. to fold the two parts of the divided Web together, one-half of the divided web passes over the former 72 and between the cuttingcylinders 39 and 40, where the other half of the web, which passes over the former 7.1, is associated with it, such web passing over a pastingcylinder 96 and thence across, as shown in Fig. III. I

Where two presses are used which are provided with a single folder, as shown in Fig. IV, the press 2 is provided witha former 97 and the press 3 with a former 98, which are in all respects similar to each other. The web from the former 97 passes from the former, between cutting-cylinders 99 100, thence between guide-rollers 101 102 103 104 and 105 106, thence between folding-rollers 107 108. The web from the press 3 passes over the former 98, thence between cutting-cylinders 109 110, thence between guide-rollers 111 112, and thence between the rollers 103 and 105, where it is associated with the web from the press 2 and thence passes downward between the rollers 104 and 105, thence between the rollers 105 and 106 to the folding-rollers 107 and 108, where it is folded by suitable knives. It is understood, of course, that the guiderollers are provided with suitable tapes, as usual. The same devices for slitting the web When it is desired are provided in connection with the formers .97 and 98 as are provided for the former 24,

The formers 71 and 72 are also provided with similar slitting devices.

In printing an. ordinary eight-page paper the form of press shown in Figs. I and II is preferably used, in which a single former 24. is provided. To produce two eight-page papers, two rolls would be used, and the terms would then be arranged as shown in Fig. XV, the forms 113 and 114 being placed upon the cylinders 9 and 10 and the forms 115 and 116 upon the cylinders 13 and 11, the pages being arranged upon the forms as indicated by the numbers in the drawings. The webs 1S and 66 would run through separate folders and would not be associated. A doublewidth web would be used to print eight-page papers, and the web from one of the rolls, as 5, would pass over one former and the web from the roll 6 would pass over another former. In the drawings only one former is shown, as the webs are to be associated; but

in printing two distinct eight-page papers an additional former would have to be provided. The imposition of the forms for producing two eight-page papers is shown in Fig. XV. In this way two complete eight-page papers may be printed at the same time on the form of press shown in Fig. I. If desired, only one of the printing mechanisms need be equipped with forms, in which case onlyone web would be used and half the product produced. To print a sixteen-page paper, the same press would be used; but the arrangement of the pages on the forms would be as shown in Fig. XII, and instead of running the webs 18 and 66 through separate folders they would be associated between the rollers 20 and 21, as indicated by dotted lines in Fig. I, the roller 20 being in this case an ordinary roller similar to the roller 21.

To printa reduced eight-page paper,a press with a single former would be used and the pages would be arranged on the forms,as shown in Fig. XVI, the forms being arranged in a manner similar to that in which they are arranged for printing a fullsize eight-page pa per. Instead of makingt-he pages on one side of a form full length,they would be made halflength, as shown in Fig. XVI, one-quarterof the form being left blank, by which arrangement the waste of paper which would otherwise oecur should the forms be arranged entirely across the press is avoided, as a web may be used of only three-fourths the ordinarywidth. Bythis arrangement also should it be desired to insert any new matter or insert display advertisements all that would be necessary would be to lengthen the short pages, correspondingly increasing the width of the web. The width of the pages would all be the same, and therefore special mechanism for driving the machine diiferently in order to properly cut the paper would not be necessary. Many other advantages incident to this arrangement will occur to the printer. In this case the webs 18 and 66 would run 5 described.

through separate folders, as described for the full-size eight-page paper.

In printing a full-size twelve-page paper the webs 18 and 66 would be associated as described for the sixteen-page paper and the paging would be arranged as shown in Fig. XIII, the forms being arranged as above One-half of the forms 113 and 114, however, would be left blank, thereby permitting of the use of a web 18 of half the usual width, and consequently effecting a saving of paper. The arrows in each of the figures indicate the direction in which the web would move with respect to the forms.

In a reduced twelve-page paper the pages would be arranged as shown in Fig. XIV and the webs would be associated as described for the full-size twelve-page paper, Fig. XIII. The third quarter, however, of the forms 113 and 11a would be left blank and four half-pages would be printed by the forms 113 and 114, as indicated. By this arrangement a web 18 of only one-quarter the usual width would be used. Any additional matter or advertisements would be inserted on the half-pages on the forms 113 and 114.

In Fig. XVII is shown the arrangement of the forms and pages for printing a reduced sixteen-page paper in which one-quarter of the forms 113and 111t is left blank. The operation in the ease of a reduced sixteen-page paper would be similar to that shown for the twelve-page paper.

For printinga thirty-mo page paper either the two separate presses connected to a single folder (shown in Fig. IV) may be used or a single press having a double former, as shown in Fig. III, in the latter case the press being of double width. If the two presses are used, on one press would be placed forms 121, 122, 123, and 12st and on the other would be placed the forms 117, 118, 119, and 120, as shown in Fig. XVIII, the pages being arranged on the forms as there indicated.

By using the form of holder shown in Fig. III and arranging the pages as shownin Fig. XIX instead of one thirty-two-page paper two of sixteen pages each may be printed. A single press with two formers, as shown in Fig. III, is used for printing two sixteen-page papers.

For printing two twelve-page papers the form of press last mentioned would be used and the pages would be arranged on the forms as shown in Fig. XX.

For printing one twenty-four page paper the double presses with a single folder would be used, and the pages and form would be arranged as shown in Fig. XXIII. One-half of one of the presses, however, would be disconnected, as indicated.

For printing one twenty-eight-page paper the double presses with a single folder would be used and the pages and form would be arranged as shown in Fig. XXII.

For printing one twenty-page paper double presses with a single folder would be used, and the forms and pages would be arranged as shown in Fig. XXI, one-half of one of the presses being disconnected.

I have described the form of press shown in Fig. III, which is provided with two formers, as being of double Width; but I do not wish to limit myself to making the press of any particular width, as it is evident that that may be altered as desired. Neither do I wish to limit myself to'making the form of press shown in Fig. VII, in which two pressses in connection with a single folder are used of any particular width, as they may be made of any desired width, depending 011 the size of the paper or the number of sheets which it is desired to produce. A sixty-four-page paper could be printed on the form of press shown in Fig. VII by making each press of double width. The columns of the pages'are arranged parallel with theaxis of the cylinder and not in-the manner shown in Letters Patent No. 399,659, dated March 19, 1899, No. 415,321, dated November 19, 1889, and No. 410,271, dated September 3, 1889, granted to me, all of which print and fold without turning or reversing.
