PERFECTING PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 252,153, dated January 10, 1882.

Application filed April 14, 1881. (No model.)

To all whom it may concern: Be it known thatl, JOHN H. S'roNEnETz, a resident of Erie, Erie county, Pennsylvania, and a eitizenot' the United States, have inventednew and useful Improvements in PerfectingPrintingLMachines; and I do'hercby declare that `the following is a. full, clear, andV exactdescription thereof, reference being had tothe accompanying drawings and the letters orlgu'resof reference marked thereon.

Myinventiourelates to what are known y as web perfectingprinting-presses; 7 audit consists iii various improvements thereon, as-xviil hereinafter be fully described and pointed out. Many `of the said yimprovements arenot, however, limited in their functions to a web-press nor to af perfecting-press, but are susceptible of use on variousforms of presses.

' My invention isiilustrated in the accompanying drawings as follows: y

'Figure 1` isaperspective view. Fi g. 2 is a longitudinal vertical section. Fig. 3 is a like viewto Fig. 2, but shows an alternative mechanism for operating the sheet receiving andredeliveri'ng rack.

The parts show-n `are designated by letters of reference as follows:

y AA, &c., are the main or central frame, and A is the arch or upper part thereof. These sustainand support the type-cylinder and the impression-cylinders.

B B," &c.,lare the frame-work, holding the feeding, lreversing, and folding devices which accompany oneimpression-cylinder. It is attachedto and forms awing` upon the central frame, and-is tobe duplicated around the centralframe as impressionfcylinders are added, one ofxw'hich onlymis `shown in full.

f `C is thetypecylinder, and alsobears the inkdistributing *plateN andthe forms F in turtle'sffjww i D,&c.,are impression-cylinders, of which the drawings indicateplaces for two in Figrl, audfo'ur inFig. 2, butonlyshow one in full.

-iE-is'the driving-gearing.1 i 1- C and D arefthe gearings respectivelyA of the type cylinderand the impression-cylinder, and theylbear such a relation toleach other that *the `impression-cylinders revolve three timesI to thetype-cylinders once, thus affording one revolution for each printing-space F and one for the ink-space N.

G Gr are the type-inking rollers. H H are the feeding and cut-off rollers. I, I', I, and 1 are also inkroliers.

W is the ink-well; I), the web of paper; T, the table or paper-way, over which the sheets pass upon tapes or by other means on their way from the feeding-rollers to the impressioncyiin ders.

S is a detached sheet making the passage.

J is a vibrating or tilting rack forreceiving thesheet when printed on one side and delivering it at a feeding-point for being taken by the gripers of the im pression-cylinder and perfected.

K K K are folding-rollers forfolding the sheets whe'uprinted.

Most of the parts ofmy machine are in and of themselves old, and their construction need not be described.

The following description will enable those skilled in the art to which my invention relates i sections.

to make and use the same.

The frame-work of my machine is :made in Thus, A A, 85e., are the central frame, made very strong and'secure, so as to lproperlyhold the type-cylinder, the various limpression-cylinders, ink distributing and applying rollers, and operative gearing'. In Fig.

`l this frame-work is shown as adapted to receive two impression-cylindersv upon the part A,while in the other figure the arch A is shown as'aidapted also to receive two impression-cylinders, making four in all. The bearings or boxes of the impression-cylinders sit in the sockets can c. This frame-work may, by proper `enlargement and change of form, be adapted to receive more than four such cylinders. 14A wing-frame, B, is to be provided for eachimpression-cylinder. I show but one, but the'duplication of the same for each impression-cyl-- inder is the work of a mechanic. These 'frames contain and support the feeding, reversing, and folding mechanism accompanying each impression-cylinder.

The press may first be constructed precisely as shown in Fig. l, i. e.-having only one impression-cylinder and onelwing-franie, but having its frame A provided with sockets c,for

IOO

receiving a second im pression-cy linder. When afterward it becomes necessary or desirable to enlarge the capacity of the machine the second impression-cylinder may be added, and also a second wing-frame containing the necessary accompanying mechanism. Ifitis again found necessary to enlarge the capacity ot' the press, the arch shown in Fig. 1 is removed, and au arch such as is shown in Fig. 2 is substituted, and other impression-cy linders added, together with wing-frames resting on the lower wing-frames. During theV process of adding either ofthe above enlargements the press is in nowise disabled, but can be runat any time during said operation.

The type-cylinder C is adapted to receive all the forms. They may be of type placed in turtles or of stereotype-plates. I expect, however, that the type-forms will generally be used, as thereby the cost and time of making stereotype-plates will be saved. Y

The type-cylinder (J,in addition to the forms,- carries an ink-(llistributing plate, N, and as the impression-cylinders are geared to make three revolutions to one ofthe type-cylinder, two of them occur over the forms and one over the ink-plate N; hence one of the revolutions of the impressiou-cylinders performs no work of impression, and is what I call a blank revolution. It will be seen hereinafter that during this blank revolution the operation of reversing the sheet-takes place.. I make the inkplate N detachable from the cylinder C, so that it can be easily cleaned by means of attachingscrews n.

The forms F sit in turtles f, as is common in many forms of machines of this character. The means I employ for attaching the turtles are, however, novel, and are as follows: The outer edges of the turtles are beveled, so as to make the lower face of the turtle `broader than the top. The adjoining edges of the inkplate are beveled in an opposite direction, and a bar, c, across the face of the cylinder, which fits the space between the turtles, is also beveled in an opposite direction l'rom the bevel of the turtles, thus giving a dovetail effect. The turtles are put in place by sliding lengthwise of the cylinderinto the space between the bar c and the ink-plate N.` Of course a form Vother than a bevel or miter may be given to the edges-as, for instance, a tongue and groove or a rabbet. The novelty consists in sliding the turtles into place lengthwise of the cylinder. After the turtles are in place they are prevented from moving laterally by screws or jam-nuts. The advantage of this construction over the nlethodof attaching byboltsand nuts, as is now practiced, is that there is lio-danger of the turtles not being firmly attached, for they are attached as soon as in place, and cannot fall off if the cylinder accidentally turns, as sometimes occurs.

rIhe feeding and cutting rollers'H H are of common construction, and are operated from the shaft H2, which connects by proper gearmachine.

ing with the shaft of cylinder C, or, if desired, some other shaft. The sheet S, after being severed from the web, finds its way to the feedingpoint of the impression-cylinder by means of tapes or any convenient mechanism for conveying sheets.

One pair ot' cutter-rollers may be made to serve for supplying sheets to more than one impression-cylinder by properly timing their movement and supplying two carrying devices and au automatic detlector for changing the direction of movement of the sheets.

The impression-cylinders are of common con` struction, and receive and present the paper to the types in no novel manner.

The essential featnreof myinvcntion relates to the means for reversing the sheet after the tirst impression, or, in other words', to the means whereby, as the sheet has passed from the impression-cylinder head foremost, it is again fed directly to the press tail foremost, and hence vin position to print the reverse side, or, as it -is known to the trade, perfected,7V thereby causing bothimpressions to be made upon-one impression-cylinder, or, if desired, upon two impression-cylinders, before the sheet leaves the The means which I use `to accomplish this result consist 0f appliances by which, after the sheet leaves the impression-cylinder after the nrst impression, it is carried (lifted or depressed, as the mechanism may be arranged) past the center of motion of said cylinder, and thus brought to a position for being griped at its tail end by the gripers of the cylinder and carried to the press for perfection; or if it is desired to use two cylinders, one for the first impression and one for the second, the said devices will carry the sheet from one to the other.

rI he mechanism for reversing the sheet is as follows: J is a table or rack, which lies upon the rollers K, and is in position to and does receive the sheetv after the tirstimpression. As soon as the sheet has leftthe cylinder and passed upon the rack J it ceases to move, and stands with its tail end projecting off the end of the rack. As soon as the sheethas reached this position the rack tilts by means of the rod J', which connects with proper gearing at some convenient point-as, for instance, the shaft of the cylinder C-movin g the crank or bellcrank lever J. This movement carries the sheet up so that the end which sticks over the end of the rack is atthefeeding-point. `This position of the rack J is shown by dotted lines. (See Fig. 2.) As soon as the impression-cylinder has madethe blankrevolution above namedits gripers take the half-printed sheet from the rack J and carry it to the second form and perfect it. During the operation ofperfecting the sheet the rack J. remains up until the sheet haspassed sufliciently from the impression cylinder to -stand with its center over the space between the rollers K. Then the rack drops, and a projectiomj, on its under side acts as a starter, and starts the sheet to doubling between the IOO IIO

rollers K. This last action is, however, for a four-paged sheet. Il' the sheet is eight paged, the gearings which regulate the movement of the rack J are so set as to allow the rack to come down before the sheet begins to pass from the cylinder D, and a stop is xed at the proper point, so that the projectionj on the rack will not sit clear into the space between the rollers K, but will act as a deiiector to turn the sheet and cause it to pass between the rollers K and go to the rollers K for the rst fold.

The mechanism for reversing the sheet may.,

be varied or modified. Thus, in place of a tilting frame a parallel-rising frame may be used with oblique levers like the side of a parallel rule, which will, as it rises, move laterally and carry the sheets tail ends to the gripers.

Such a construction is shown in Fig. 3, wherein J is the table or rack, asin the other figures.

l and 2 are the arms. 3 is the rock-shaft 5 4,

the arm by which the rock-shaft is tilted 6, a connecting-rod, and 5 the cam for operating the device. The table is shown in full lines as elevated and in the act of redelivering the sheet tail foremost to the gripers. In Vdotted lines it is shown as down in position to receive a sheet after the first impression.

Much of the folding apparatus is not shown, butenough is shown to illustrate my invention; and as the construction of said folder beyond its location forms no part of my invention it is deemed unnecessary to show more than is shown.

The ink-distributing roller I is on the main driviug-shaf t of the press. This is very ad vantageous, as it requires no gearing, and hence there is no danger of breaking the same if the ink is too stiff, as is sometimes the ease, especally in cold weather.

What I claim as new is- 1. In a perfectingprinting-press, the combination, with the im pression-cylinder thereof, of a sheet receiving and redelivering apparatus consisting of a rack or table which receives the sheet head foremost as it leaves the impressioncylinder after the irst impression and While holding said sheet changes its position, substantiall y as described, and re-preseuts the said sheet tail foremost directly to the gripers for a second impression, substantially as set forth.

2. In a perfecting printing-press, the combination, with the impression-cylinder thereof, of a sheet receiving and redelivering apparatus consisting of a vibrating rack or table which receives the sheet as it leaves the impressioncylinder after the first impression head foremost and while holding said sheet by vibrating lifts it from the lower to thc upper side of said cylinder and presents it tail foremost directly to the gripers for a second impression, in a manner substantially as described.

`3. In a perfecting printing-press, the combination of an impression-cylinder, a pair ot'folding-rollers, and a vibrating sheet receiving and redelivering rack or table which is provided with a starter-projection on its lower side, said parts being constructed and arranged to operate in the manner and relation and for the purposes substantially as set forth.

4. 1n a printing-press, the type-cylinder C,

in combination with the ink-plateN andbar o,

with inwardly-beveled edges, and turtles f, with outwardly-beveled edges, substantially as and for the purposes mentioned.`

5. In a perfecting printing-press, the combination, substantially as shown, of the following elements the type-cylinder C, with turtles f f, and ink-plate N, impression-cylinder D, `feeding-rollers H H', with cut-off knife h, sheetway T, tilting rack or table J, with start-ing and detiecting projection j, and folding-rollers K K' K". a

In testimony that I claim the foregoing I have hereunto set my hand this 26th day of March, 1881.
