PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 70 dated y 15, 1902- Application filed June 25,1901.

To all 2071 0772, it may concern.-

Be it known that I, JOSEPH L. FIRM, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Printing-Press, of which the following is a full, clear, and exact description.

My invention relates to improvements in rotary printing presses designed to better adapt them to do fine work, such as magazine and similar printing where illustrations are used, and in general to do a better grade of work than is usually executed upon rotary presses.

My invention also relates to improvements in the folding mechanism by which among other results offsetting or smutting of the product is prevented during the process of folding.

. Myinvention comprises the novel features which will be hereinafter particularly pointed out in the claims.

Figure 1 is a side elevation of my improved press. Fig. 2 is a plan thereof. Fig. 3 is a detail side view of one of the rotary carriers and its attached cutting mechanism. Fig. 4: is a cross-section of two of the folding-rollers which receive the sheets from the foldingcarrier. Fi 5 is an end view of one of the folding-carriers and the folding-rollers which receive the papers therefrom. Fig. 6 is an elevation of one of the folding-rollers, and Fig. 7 is a side elevation of a modified arrangement of printing-cylinders. Fig. 8 shows the shaft and two sets of rollers which carry the tapes of both delivering mechanisms.

The form-cylinders C D shown herein carry forms F, which cover only half the surface of the cylinder, said forms being shown as arranged adjacent each other, one half or side of the cylinder being covered by the forms, while the opposite side is blank. The forms necessary for'printing one side of the web are located one half upon the cylinder C and the other half upon the cylinder D. The forms upon one cylinder are so located with reference to the forms upon the other cylinder as to print in the spaces left blank by the forms of the other cylinder. Both these form-cylinders cooperate with a common impression-cylinder B, which lies between them, while inking Serial No. 65,903. (No model.)

mechanisms H and I engage, respectively, the form-cylinders C and D.

The web A is of a width equal to half the length of the form and impression cylinders and is printed upon one side by the forms on one end of the cylinders and is then turned and presented to the forms at the other end of the cylinders for printing the other side. The web upon leaving the roll is conducted about the roller 1, the impression-cylinderB, and roller 2 to the turning-bars 3, which reverse the web and shift it to one side into line with the other end of the form-cylinders. It is then led over the roll 4, about the impression-cylinder, and then to the cutting and folding mechanisms. As the web is led to the im pression-cylinder for its second passage an offset-web is combined with it, this offsetweb appearing as the roll G. After passing about the impression-cylinder with the printed web the offset-web is separated therefrom and wound up as the roll G.

The carriers E E each have a cutting-knife, pins, and a folding-blade arranged so that they alternately sever a section of the web and present it to the rollers of a folding apparatus. These parts of the carrier are constructed and operate like the similar parts in carriers of the ordinary and well-known sort, except as hereinafter pointed out, and particular description thereof is deemed unnecessary. I have herein shown only two such carriers, as that number will accomplish my present purpose. It is, however, evident that more such carriers might be employed, if desired, the novelty lying in the employment of a plurality of such carriers, each of which in turn receives the sections successivelycut from the web.

The knife 8 of the carrier E enters a corresponding groove in the carrier E, and the pins 7 engage the edge of the paper to convey the paper about the carrier E. NVhen the carriers have made a half-turn,-the knife 19 upon the other carrier cuts the web, and the folding-blade 9 presents the section out off to the folding-rollers 10 11.

lVhen the knife 19 cuts the web, the pins 20 engage the web to convey it about the carrier E until a half-revolution is made, when the knife 8 of the othorcarricr sovors another the folding-rollers 22 23.

section, which is presented by the blade 21 to I The two carriers thus alternate in presenting sections of the web to their respective folding mechanisms.

About the folding-rollers 11 and 10 respectively pass series of carrier belts or tapes and 51, which are located so as to engage the paper only in the marginal spaces between the pages,-the bolts 50 also passing about rollers or pulleys 12, 14, and 16, while the belts 51 pass aboutrollers or pulleys 13 and pulleys 22 25 27 and rollers 15*, correspondingwith rollers 15. Carrier-belts 53 pass about rollers or pulleys 23, 24, 26, and 28. The tapes or belts 51 and 52are offsetsufficiently as to not interfere with each other, and the rollers or pulleys 15 and 15 are correspondingly separated lengthwiseof the shaft, as clearly shown in Fig. 8. The two sets ofrollersare capable of turning inde pendently of each other, as by having one or both sets loose upon the shaft, whereby they are enabled to turn in oppositedirections, as is required for the proper operation of the device. The two sets of carrier-belts lead from their respective carriers to a common point,delivering their folded sectionsto a common set of rollers 3.0 and 31. A guide 17 is placed between the courses of the two sections ofpapers where they converge and two other guides 18 at each side of said apex to proppaper sections to the rollers 30 which isdelivered to one will be superposed on the section which was delivered to the other, thus doubling the size of the signature when completed. This variation of speed may be secured by any well-known means. The means shown consists of wheels'54 55, secured together, wheel 54 driven by direct engagement with wheel 56, .turning with the cylinder E, and wheel 54 turningwheel 22 of. the upper or accelerating set of tapes,while wheel 56 directly drives wheel 10 of the lower tapes by engaging a wheel 57, turning therewith. The upper set, consisting of the carrier-belts 52 53, are herein intended to run at a speed in excess'of the other or lower set, thus delivering its section of the web to the rollers 30 31 at the same time as that coming fromthe lower carrier E. The rollers 26 and 27 have ribs projecting therefrom and adapted to engage the folded paper in its passage to giveit'an additional acceleration, if needed,

Carrier-belts 52 pass about the rollers or to secure proper registry with the other section. These rollers may be adjusted to cause more or less acceleration, as desired; 32 and 33 represent slittors by which the sections are slit longitudinally.

The carriers E and E and the rollers over which the carrier-beltspass are of a peculiar construction, shown in Figs. 3, 4, and 6. The carrier, as shown in Fig. 3, consists of a cylinder which has cir :nmferential ribs or projecting bands 6, so located as to engage the web only on the line of the marginal spaces between pages, thus avoiding all contact with the printed su faces and preventing smutting the printed n The foldinge are similarly constructed, as shown in 4 and 6. In many cases at least it be suiiiciont in their case to omit the intermediate ribs and use only ribs at the ends of the rollers, as shown. in Fig. 6.

By the above con. .ruction of the rollers the In Fig. 7 a diflierent arrangement of the printing mechanisms shown, the turningbars being omitte and an upper and lower deck employed. In a figure the forms F are shown as cXtendng-half-way around the form-cylinders L, M, O, and P. The web after printing is to be conveyed to a folding mechanism similar to that described,and iilustrated in Fig. 1.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A printing-press having an impressioncylinder and a pair of form-cylinders of the same diameter as the, impression-cylinder for printing one side of a web, each form-cylinder having forms secured thereto to cover longitudinal sections thereof comprising substantially half the surface of the cylinder, the forms of each form-cylinder being adapted to print upon the space left blank by the forms of the other form-cylinder.

2. A printing pressh'aving a single impression-cylinder and two form-cylinders of the same diameter as the impression-cylinder for printing one side of a web, each of said formcylinders having forms covering alongitudinal belt extending half about the cylinder, the two form-cylinders being timed to print on alternate sections of the web.

3. A printing-press having a single impression-cylinder and two form-cylinders placed on opposite sides thereof, forms arranged on each of said cylinders to print one-half only of the web, the forms of one'cylinder printing in the spaces not printed by the other cylinder, means for presenting a half-width web to one end of the impression and form cylinders to print one side thereof, and means for turning and presenting the Web to the other end of the said cylinders to print the other side thereof.

4. In a printing-press the combination with means for perfecting a web, of a plurality of carriers adapted to each receive in turn the successive sections of the web, a folding and conveying mechanism for each carrier, said conveying mechanisms all leading to and delivering their web-sections at a common point and being speeded to deliver the sections of each series synchronously and superposed.

5. In a printing-press the combination with means for perfecting a web, of two rotary carriers adapted to receive the web between them and provided with web-cutting mechanisms, means whereby successive signatures are taken alternately by said carriers, two folding and conveying mechanisms receiving the signatures each from its respective carrier and delivering them at a common point, and means for driving one of said conveying mechanisms at a speed in excess of the other whereby the signature from one conveyer is delivered superposed on the other to form a single product.

6. In a printing-press the combination with means for perfecting a web, of two rotary carriers adapted to receive the web between them and provided with web-cutting mechanisms, means whereby successive signatures are taken alternately by said carriers, a set of folding-rollers for each carrier adapted to receive the signatures therefrom, conveyers leading from said folding-rollers to a common deliverypoint, and means for accelerating the passage of the signature through one conveyer whereby the signatures from both conveyors may be superposed to form a single product.

7. In a printing-press the combination with means for perfecting a web, of a plurality of primary folding mechanisms adapted to receive in turn the successive sections of the web, secondary folding mechanisms and means for simultaneously delivering in superposed position web-sections from all of the primary folding mechanisms to the secondary folding mechanisms to form a single product.

8. A paper-folding device comprising two rotary carriers having cooperating web-cutting members adapted to sever the web into semicircumferential sections or sheets, each carrier having sheet-holding and sheet-folding means, said carriers being timed so that the sheet-holding and sheet-folding means of the respective carriers alternately engage the successive semicircumferential web sections or sheets.

9. A paper-folding device comprising two rotary carriers having cooperating web-cutting members adapted to sever the web into semicircumferential sections or sheets, each carrier having sheet-holding means adjacent one of its cutting members, said carriers being timed so that the sheet-holding means of the respective carriers engage alternate sheets, a folding-blade upon each carrier located ninety degrees behind the sheet-holding means of the same carrier and folding rolls receiving the sheets from said foldingblades.

10. In a printing-press the combination with two rollers adapted to receive the perfected web between them, and cutting mechanisms acting twice for each revolution of said rollers, of Web retaining and folding mechanisms carried by said rollers and engaging alternate web-sections.
