ROTARY PRINTING-MACHINE.

To all whom it may concern Beit known that I, Gusrnv Brssnvenn, of

Augsburg, in the Kingdom of Bavaria, have invented new and useful Improvements in Rotary Printing-Machines, which improvements are fully set forth in the following specification, reference being had to the accompanying drawings.

' rlhe said invention relates to improvements in and connected with rotary printing machines, wherebythey are more especially adapted for printing illustrations and pictures.

In the accompanying drawings, Figure l is a longitudinal sectional elevation `ot' a machine embodying my improvements. Fig. 2 represents the lower inkin g apparatus by a side elevation, partly in section. Fig. 3 is a similar view, showing a modification of the inking appara-tus. Fig. 4 is an end elevation, partly sectional, of the worm-carryin g shaft, that transmits certain movements to the ink-distributing rollers. Fig. 5 is a plan view of a portion of the inking lapparatus, showing particularly the devices for reciprocating the inking-rollers. Fig. 6 represents, by a part plan and part sectional view, a portion of the rollers oi' the inking apparatus when removed from their actual positions Vand placed in peripheral contact in the same plane. Fig. 7 is a plan, and Fig. 8 a longitudinal sectional elevation, ofthe inhing-tr'ough. Fig. 9 is a side elevation, and Fig. 10 an end elevation, of the sheet-delivery apparatus.

Like letters indicate the same parts throughout the drawings.

This machine is designed to operate upon a web of paper, which, in the form of a roll, as A, has its end led in the usual manner to the printing mechanism. It is here shown as passing through a moistening or damping apparatus, B, and thence between two calendering or smoothing rollers7 G, and between the surface ot' the lower type-cylinder, P u, and that of the lower impression-cylinder, D u. whereby it receives the so-called 4 prime,7 or flrst impression, on one side. The paper thence passes partially around the upper impression-cylinder, D o, and between its surface and that ofthe upper type-cylinder, P o, whereby it receives the so-called reiterationf7 SPECIFICATION forrnngpart of Letters Patent No. 223,981, dated February 3, 1880.

or second impression, upon its other side. The paper then passes between the two cutting-cylinders S S2, by which it is perforated transversely upon lines that determine the length of the sheets to be formed, which, by means of the two snatching-rollers W W2, are successively torn off from the web. These printed sheets are carried, by means ofthe tapes 20 2l and the rollers J J2 J3 J4 M N N2, over which they pass, to the separator VV2 and to the delivery-apparatus L' L2, by which they are laid down upon the piling-tables T T2.

The type and impression cylinders are mounted in bearin gs in a suitable frame-work,

and are geared together, so as to run in unison,"

by means of toothed wheels, as is common. The cutting-cylinders, which are geared together and provided with the usual cutters, are mounted in the frame-work and driven in unison with the printing-cylinders by means of gear-wheels 7 S 9, the latter being upon the shaft of the upper impression-cylinder, D o. The snatchingrollers W" 72 are properly mounted vin the side frame, somewhat more than a sheets distance in advance of the cutting-cylinders, and are geared to and driven from said cylinders by the train 6 6 6 6, so

that said rollers have a slightly faster surfacemovement, and hence when they nip the end ofthe web they operate to advance it rapidly and detach it on the line of perforation, thus forming single sheets and separating them a q,

suitable distance apart to admit of their being delivered separately, so that one shall not interfere with another. The rollers J', J2, J 3, J 4, and M are all driven at proper speed and in unison by the train 5 5 5, 8vo.

`The tapes 20 run from a lead-roller in front of the cutting-cylinders, under the rollers W J2 J4, over the roller M, and return over the roller N2 and suitable leading and stretching rollers. v

The tapes 2l run from a lead-rollerrin front of the cutting-cylinders, over the rollers W2, J J 3, and M, and return around the roller N' and suitable leading and stretching rollers.

In order to prevent smearing resulting from the set-ofi' from the upper impression-cylinder, an offset web, 22, runs along over said cylinder, and constantly presents a dry surface to of the fountain-roller d.

"ference with a screw-formed the paper to be printed upon, the said offset web being unrolled automatically from the roll C', passed around the rollers :1v/y', and around the upper impression cylinder, and thence around the rollers q 2 m2, and is finally rolled upon the roller ,02.

The general arrangement of the machine having been described, I will now proceed to sition ink-distributing rollers o o2 o3 04 o5 06,' -Inetal distributing-rollers m m2 m3' m4 m5 m6 m7 m8 m9 m10, the metal fountain-roller d, and an additional metal roller, as on, (see Fig. 1,) which lat-ter roller is omitted in the lower apparatus', as is hereinafter explained. This gives the upper inkin g apparatus twenty-live, and the lower one twenty-four, rollers in all, which provide the means for accomplishing a very fine distribution of ink.,

Althoughv each type-cylinder is shown as having seven hiking-rollers, a a2 c3 a4 t5 a6 al, fouronly need'be used, as is illustrated in Fig. 3. The roller o4 is provided on its circumelevation, as is shown in Fig. 6. The metal distributing-rollers m m3 and m5 m6 fm7 m8 m9 are each provided with toothed wheels, through which they receive their rotary motion from the wheel R (fast upon the shaft of the type-cylinder) by means of the intermediate wheels, r r2 r3 r4 r5, and at the same time transmit their -rotary motion to the composition distributingrollers by means of peripheral friction.

The fountain-roller d receives its rotary motion by means of the worin S, which is fast upon one end of the transverse shaft 16, that supports the intermediate wheel, r4. This worm S engages with a worm-wheel, S', on the shaft S3, which carries a worm-wheel, S2, that gears with a worm, S4, that is fast on the shaft The fountain is provided with an ink'or color doctor, p, that is arranged in such relation to the roller d as to allow the proper quantity of ink to pass and yet free the same from any impurities.

The metal rollers mfg/m5, and com position rollers o', o5, and o3 have, in addition to their rotary motion, a longitudinal or endwise movement, the extent of the latter movement not being alike in all the rollers and not taking place at the same time, whereby the said rollers will arrive alternately at the end of their endwise movement. This endwise movement is effected by means of the pivoted vibratin g levers 7c3 7a4 165, the ends of which levers play between collars on the shafts of said rollers, receiving their to-and-fro or vibrating motion by means of the eccentric pivot c, Figs. 2 and 5, applied to the upper end of the shaft 7:2, which 'The eccentric pivot 7c -viding-roller o4, as follows:

shaft is revolved by means of a bevel-gear wheel, SG, fast upon the lower end, which engages with a similar wheel, S7, on the shaft S3.

The levers h4, which move the rollers o 05, are fast upon a rock-shaft, 3, and the upper lever, 7c, has an arm, 2, that is pivoted at 4to an arm, 1, that is fast to a rook-shaft,11, that also carries the lever 7c3, that moves the roller o3. is linked to the pivot 4c The levers 705, which move the rollers m3 m5, are fast upon a rock-shaft, 13, that is rocked by means of an arm, l5, to which is pivoted alink, 14, that is also hung upon the pivot k.

This arrangement of levers so operates,and the movement of the rollers is such, as to cause the ink to be transmitted to the form-rollers and applied to the type-cylinders in the finest layers possible, whereby a perfectly deep-black covering of the printing-surface is effected by an arm, 12.

without running the risk of unduly coating the fine lines, and thus injuring the finest details of the illustrations as regards their purity.

By the arrangement and operation of this inking apparatus it will be observed that the seven form-inking rollers receive the ink equally divided from nection with them-that is to forminking rollers a a2 a3 a4 on one side and the three a5 a6 a7 on the other side receive equal quantities of ink by the action of the di- The ink is taken from the fountain'roller d by the roller m9, and thence transmitted, through the roller 03, to the roller m8. From the roller mu the ink is equally divided and distributed on one side upon the four form-inking rollers a a2 a3 a by the roller o2 and the intermediate rollers, m6 o m3, and on the other side upon the three form-inking rollers a5 0.6 ai' by the roller o4 and the intermediate rollers, m7 o5 m5.

The uniformity of distribution is effected by y the roller o4' only taking olf, with its spirallyformed elevations t', from the roller ma corresponding stripes of ink, which are transmitted to the roller m7. half the diameter 'of the roller o, the stripes of ink transmitted to the former will not be separated from each other, as they were on the roller 04, but they will be placed closely side by side-that is to say, the yroller m7 will be covered with color uniformly on its entire sur- The spiral stripe of ink remaining upon the roller m8, not being taken off by the roller o, will be transmitted to the roller o2, and thence to the roller m6, in the -same manner as described with regard to the transmission from the roller 04 to the roller m7. i

The roller 04 may have its surface divided by other forms of removed parts; butthe spiral form is the most practical, for the reason that it removes and leaves a continuous line of ink, and thus aids a perfect distribution.

I must remark here that in ,the upper inking apparatus the distributing-rollers are disposed of differently from those used in the lower inking apparatus. The rollers o, m7, and 05- are This roller m7 being of one- IIO placed where the rollers o2, 'm2, -and'o are located in the lower inking apparatus, and vice versa, for the reason that the upper type-cyl-` inder rotatesvin an opposite direction to the rotation of the lower type-cylinder, on account of the. course the printing-paper takes. (Jorn-Y sequently the rollers of the upper inkingr apparatus must turn in an opposite direction to .the rollers of the lower inking apparatus.

Now, it' the roller o2 were to `be arranged above the roller m2, it would take away from the latter all inking-color, and would not leave i any at all for the roller 04, supposed to be arranged below the roller m2, and as the fountain should be arranged as in thelower apparatus, and its roller d turn in the same direction,it is also necessary to add the intermediate ink-roller, m, as shown.

One feature ot' the present invention is found in the peculiar arrangement of the irnpression and type cylinders, which may be' briefly described as consisting in mounting the lower type-cylinder on one side of its impression-cylinder instead of` vertically below the three other cylinders, as is now commonly done. This admits of the arrangement ofthe inking apparatus for the lower type-cylinder in exactly the same manner as thatfor the upper type-cylinder. The position and the arrangement of all the rollers are the same, this being of very great importance, especially with reference to the form-inkin g rollers, whereby the same distribution ot' ink is accomplished for both of the impressionsthat is, the impressions on opposite sides of the sheet-and consequently produces even work. By means of the sidewise position of the rollers the work of attending to the lower inking apparatus is greatly simplified, since if all the four cylinders-that is to say, the two type and the two impression cylinders-were placed vertically beneath each other, the inking-rollers for the lower inkin g apparatus would require to be arranged below the type-cylin der, which would render the work of attending to the same very inconvenient. By this arrangement of parts the whole machine may be built of less height, and consequently its upper parts may be more easily reached and less vertical space will be occupied by the machine.

It has hitherto been almost impossible to make use of lat engraved plates or those produced by the well-known galvanic method for rotating printing-machines.

Y One part of the present invention relates to means for adapting such plates to rotating machines, this being of the very greatest importance for printing illustrated newspapers and the like cut-work.

' bent it is cooled by means of any suitable con' trivance. The plate, havingthus received a permarient circular form, is fitted upon the type- VThis delivery apparatus consists of a sheetseparator and a sheet-laying device. The sheet separator consists of the two `frames formed-by the two sets of shafts c 'v2 and v2 if', having tape-rollers carrying tapes V V2, and by the two vertical levers Q12 c4, in which the shafts 'v6 c2 are carried, which levers are united with each other by bent coupling-pieces U5 and the two tape-shafts v6 t". Tapes run around the shafts c' u2 and the shafts v6 v2. Oscillating motion is transmitted to the frames by the eccentric tappets c2 and the crank-levers 02.

The laying device consists of two separate fly-frames, L and L2, which receive their vibrating motion through the two cranks of the wheel Z and the disk Z2 by means of the rodsv Z3 Z4 and the levers Z5 Z6, tted on their rock` shaftsw 102. The sheets carried outward between the tapes 2l 22 emerge from the small rollers N N2, and are, in consequence of the rocking or to-andt'ro motion of the separating apparatus, ledalternately upon the tapes V', on the left-hand side of the said apparatus, and upon the tapes V2, on the right-hand side of the same. The sheets on the right-hand side are laid ldown upon the table T2 by the delivering apparatus L2, and the sheetson the left-hand side are laid down upon the table T by the delivering apparatus L.

Having thus described my improvements, what I claim iS 1. The combination, with the two separate series of form-inking rollers and the ink-fonntain, of the roller m2 and the roller 04,' having a portion ot' its surface removed or cut away, substantially as described.

2. The combination of the type-cylinders and their inking apparatus with the impres- IOO sion-cylinders-thatis to say, the two impresv sion-cylinders and one type-cylinder arranged vertically above each other, and the other typecylinder arranged at the side ot' its impressioncylinder, while the inking apparatus for each type-cylinder is arranged on the same side ot said type-cylinders, all substantially as shown and described.

3. A rotary printing mechanism wherein one type and one impressionv cylinder are mounted side by side in, or nearly in, the same horizontal plane, and the other impression and type cylinder are mounted one above the other and in, or nearly in, the same vertical plane with the irst-named impression-cyl-- inder, all substantially as described.

4. The combination, with a single ink-founpivots, whereby said rollers are moved endwise to differenteXtents and ab different times, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. GUSTAV BISSINGER.
