HENRY A. WIsE wooo, or NEW YORK, N. Y. ASSIGNOR To THE CAMPBELL PRINTING PRESS & MANUFACTURING COMPANY, on NEW YORK, N. Y.,

A CORPORATION OF NEW YORK.

PRINTING- MACHINE.

To aZZ whom it may concern:

Be it known that I, HENRY A. WIsE W001), a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in PrintingrMachines, of which the following is a specification.

The aim of this invention is to provide a new and improved printing-machine of the to class known as reciprocating-cylinderprinting-machines, which is especially adapted for color-printing, as hereafter described; and to this end the invention consists of the device described and claimed in this specification I5 and illustrated in the accompanying two sheets of drawings, in which- Figure 1 is a side elevation of enough of a printing-press embodying my improvement to illustrate'the same. Fig. 2 is a plan of the 20 same. Fig. 3 is a sectional elevation on the line 3 3 of Fig. 2. Fig. 4 is a sectional eletvation on the line 4 4 of Fig. 2. 5 is a ."seetional elevation illustrating a modification. .Fig. 6 is a plan view illustrating a further :2 5 modification; and Figs. 7 and 8 are sectional elevations on the lines 7 7 and 8 8 of Fig. 6, .i'espectinely.

Referring to the drawings and in detail, 1 and 2 designate the usual side frames of a -ma chine,.a-nd between these side frames are .arranged form-.beds A and B, which are sub- :stantially twice .the width of the web to be gprinted. On .the side frame 1 is arranged a .guide orgib 5, and asimilar gib 6 is arranged 5 .onthe sideframe 2. ,Fitting on the gib 5 is .a yoke;7, and asimilar yoke 19 fits on the guideway 6. The yoke7has in the vertical ,portion .thereof a vertical sl ot 8, as shown, :and fitting in this vertical slot is a square block 10, which is journaled on a wrist-pin 9, carried by the gear 11. This gearll is monnted ona shaft 12, which is journaledin the main framing, and on the opposite end of. the shaft 12 is fastened a crank-arm 15, which has a crank-pin 16, which carries a square block 17, which fits in a slot in the yoke 19. The gear 11 is driven by means of pinion 14, mounted on shaft 13, and this shaft 13 may be the shaft to which power is applied to op- 50 crate the machine.

Patent N0. 694,597, dated March 4, 1902.

Serial No. 551,290. (No model.)

Extending up from the yoke 7 are brackets 20, and extending up from the yoke 19 are brackets 21. Journaled in these

brackets

20 and 21 are impression-cylinders O and D, .which are adapted to coact with forms placed upon the stationarybeds. It will be seen that as the gear 11 and crankarn1 are revolved the wrist-pins will communicate a reciprocating motion to the cylinders, and this reciprocating motion will be a very smooth and easy one, as no pitmen are used. This driving mechanism for the impression cylinder or cylinders is applicable to any form of reciprocating cylinderprinting-machines. Mounted between the brackets and 21 are rods or shafts 22, 2.3, 24, and 25. As hereafter described, the web is led twice around .each impression-cylinder, so that when the same is pulled or fed forward the web will move oppositely around these parts.

The rods22, 23, 24, and 25 preferably are rigidly mounted between the

brackets

20 and 21, On these rods are fastened suitable col; lars 30, and between these collars are mounted rollers E, whereby when the web is pulled forward it can turn these rollers on each of said rods in different directions.

Between each of the

brackets

20 and 21 are arranged suitable inking-rollers I I, to which ink may be supplied in any of the usual ways and which are adaptedto ink the forms.

From the shaft 13 power is transmitted to a longitudinal shaft 43 by means of a pair of bevel-gears 420. The shaft 43, by means of a bevel-pinion 44 and a bevel-gear 45, turns shaft 48 and also, by means of bevel-

gears

49 and 50, turns vertical shaft 51. This vertical shaft 51, by means of bevel-

gears

52 and 53, turns

rollers

34, 35, and 36, which are geared together. go

On the shaft 48 are arranged suitable cams 46, and bearing on these cams are arms 39, which may be mounted in the main frame and thelower ends of which may be forked to straddlethe shaft 48. These arms 39 have 5 .rollers,42 bearing against the face of the cams in the ordinary manher. Springs 47 are used to keep the arnisfnormally i ntheir lowest position and the rollers 42'agaihst the cams 46. Journaled in these arms 39' are s'uitable'roll-

10c ers

37 and 38, which perform the function of looping rollers, as hereafter described. These looping-

rollers

37 and 38 cooperate with

rollers

40 and 41, mounted on the frame, as shown.

On the righthand end of the press are mounted two turner-

bars

31 and 32, arranged in the same horizontal plane, which are adapted to deflect the web, so that the same may pass again around the impression-cylinders and be again printed thereby, whereby the machine as organized in Figs. 1 and 2 forms a four-color-printing machine. It will be seen that the deflector device is arranged in substantially the same horizontal plane as the guide 25. By this arrangement the web may pass from and back to the impressioncylinder without intermediate guides and can be manipulated with slight strain.

The path of the web through the machine is as follows: A web-roll 54 is mounted in any of the usual manners near the end of the press, and from this roll the web is led up over the continually-running roller 34, under the roller 35, and up over the roll 36, then over roll 40, down under looping-roller 38, up over roller 41 to the guide 22, carried by the moving carriage, then around impression-cylinder O, up over guide 23, across to the guide 24, under the impression-cylinder D, up over the guide 25, and then up over the turner-bar 31, laterally across the press, and then down over the turner-bar 32 back into the press, parallel with its former path. It will be seen that as the web runs over this turner or deflector device the same will be transferred laterally and will assume a pathway parallel with its original direction. It will also be seen that the printed side of the web will not touch either turner-

bar

31 or 32. Hence there will be no smut on the printed side of the web.

Referring now to Fig. 4, it will be seen that the web from the turner-bar 32 is led back over guide 25, around impression-cylinder D, over guide 24, to guide 23, aroundimpressioncylinder 0, up over guide 22, under guide 41, up over looping-roller 37, under the guide 40, then under the continually-running roller 36, up over the roller 35, and down under the roller 34, which will act to deliver the web from the press, and it will be seen that the same set of continually-running rollers will feed the web both into and out of the press,

lVith a press thus organized the sheet can be given four impressions in as many colors, and hence the machine is what is technically known as a four-color-printing machine. The looping-

rollers

37 and 38 are so timed that while the cylinders are in impression they will take up the web unwound from the roll 54 by the continually-running rollers and will pay the web out to the

rollers

34, 35, and 36; but as the cylinders reverse in either direction the web will be shifted the length of a sheet. The press is thus organized to print two complete sheets for each forward-andbackward reciprocation of the impression-cylinders. The impression-cylinders are geared to racks on the side frames, as shown, whereby they will turn and always be kept in register with the forms.

Half of my machine may be used to print two colors, the web being fed through the press in one direction only. This can be done as shown in the diagram in Fig. 5, in which instead of turning the web back para'llel to its original pathway the web from the guide 25 is carried out by guide 410 over a looping-out roller 310, up over a guide-roller 400, and then into the bite of feeding-out

rollers

360, 370, and 380, which may be continually driven to feed the web out of the press. Of course it is understood that this feeding-out or delivery device would be simply added to the press shown in the first sheet of the drawings without changing any of the parts shown in Figs. 1 and 2.

Another way in which I may use the press shown in the first sheet of the drawings for two-color work is to lead the web through the press so that the same will not pass under two oftheimpressionsurfaces. Forinstance, I could lead the web from the turner 32 directly to the roll 41, thus utilizing the parts of the impression-cylinders next to the frame 1, or I could lead the web from the roll 40 directly to the first bar 31 of the turner, and thus utilize only the other half of the impression-cylinders, or, further, I could use either or both impression-cylinders simply by not leading the web under the parts of the impression-cylinders which it is desired to omit, or I could use my press as a three-color press by simply leading the web so as not to pass under one-half of one of the impression-cylinders.

It will be seen that the guides travel with the impression-cylinders, and each set thereof is so arranged that the web could be led from one directly to the other without looping or passing the same down under the impressioncylinder.

Another way in which a two-color machine may be arranged is as shown in Figs. 6, 7, and 8. In this case only oneimpression-cylinderF is used and only one bed G. The'web is led from the roll to this cylinder in the same manner as it is led to the cylinder C of the previous device and then is led directly to the deflector device and is directed back parallel with its original pathway, again around the impression-cylinder F, and delivered from the press by the looping-roller 37 and the

rollers

34, 35, and 36, as before described. It will be seen that the web-manipulating device is arranged at the opposite end of the machine relatively to the deflector, whereby the operative and moving parts can be very simply and easily adjusted and nicely operated. The particular web-manipulating mechanism, as before described, consists of means for continuously feeding the web into and out of the press and a device, as the loopers, for respacing the web. Other forms of web-manipulating devices to properly shift the web in the machine at-the right time may be used. A press as thus organized comprises a very neat and simple two-color machine and illustrates the simplest form of this present invention.

The details herein shown and described are not exactdetailsof the working-device, as in a practical machine some of the rollers would have to be made adjustable for register; but these details are omitted, as they are so well known to the ordinary printing-press mechanic that they can be easily supplied in the practical machine.

It is understood, of course,in describing the operation of the machine that a formi's' placed upon each bed, and it is understood, of course, that ink is supplied to the inkingrollers so that, ifdesired, these forms can receive different-coloredinks.

The arrangement of parts herein shown and described may be greatly varied by a skilled mechanic without departing from the scope of my invention as expressed in the claims. 'Having'thus fully described my invention,
