SPECIFICATION forming part of Letters Patent N 0. 643,692, dated February 20, 1900. Application filed September 27, 1899. Serial lie-731,799. (No model.)

To all whom it may concern:

Be it known that I, BERNARD H. SPEOK- BAUCH, a citizen of the United States, residing at Newport, Campbell county, Kentucky, (post-office address, 332 West Ninth street, Newport, Kentucky,) have invented certain new and useful Improvements in Printing- Presses, of which the following is a specification.

This invention pertains to improvements in perfecting printing-presses adapted for single-color or multicolor printing; and the improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in WhlCl1- Figure 1 is aside elevation of a printingpress exemplifying my improvements; Fig. 2, a view from a similar direction, one of the housings being removed and the printing, impression, and inking rolls appearing in vertical section in the plane of line a of Figs. 4,

5, and 9; Fig. 3, a side elevation of one of the printing-cylinders, illustrating a construction peculiarly adapted for use in the printing of the longitudinally-striped portion of flags as, for instance, the American flag; Fig. 4, a view of the face of the web as produced by the printing-cylinder illustrated in Fig. 3; Fig. 5, a longitudinal section of the printingcylinder shown in Fig. 3, the section appearing in the plane of line 6 of Figs. 2, 6, 7, and 8; Fig. 6, a vertical transverse section of the same printing-cylinder in the plane of line d of Figs. 3 and 5; Fig. 7, a similar section in the plane of line 0 of Figs. 3 and 5; Fig. 8, a similar section in the plane of line (Z of Figs. 3 and 5; Fig. 9, a side elevation of the impression-cylinder, and Fig. 10 an end elevation of a portion of the impression-cylinder.

In the drawings, referring for the present exclusively to Fig. 2, 1 indicates the side housings of the press; 2, the impression-cylinder; 3, its elastic jacket, as of sheet-rubber 4:, the upper printing-cylinder, carrying a printingform for the upper side of the web or sheet to be printed, this printing-cylindercooperating with the impression-cylinder and mov ing at the same peripheral rate of speed; 5, the lower printing-cylinder, carrying a form corresponding with the lower face of the web or sheet to be printed, this printing-cylinder cooperating with the impression-cylinder and moving at the same peripheral rate of speed; 6, inking-roll for the upper printing-cylinder; 7, inking-roll for the lower printing-cylinder; 8, supply-roll of the fabric to be printed; 9, a pair of draw-rolls, the fabric from the sup ply-roll 8 passing between impression-cylinder 2 and upper printingcylinder 4 and thence between the draw-rolls, the draw-rolls and the three cylinders having, preferably, the same diameter and all moving at the same peripheral rate of speed.

Let it be assumed that the opposite surfaces of the web are to be printed alike in exact register with each other-as, for instance, in the American flagshowing alike on both sides, the two sides being in exact register,.but one side being the reverse of the other, or, so to speak, one side right-handed and one side left-handed. Assume the press as being .employed for the production of the red or striped work of such flags. In such case both ink-rolls 6 and 7 are to supply red ink to their respective printing-cylinders.

As the web passes between the impressioncylinder 2 and the upper printing-cylinder 4 the upper surface of the web will obviously become impressed by the form carried by the upper printing cylinder, such impression, however, being, as usual, the reverse of the form which produced it. At the same time the lower printing-cylinder 5 prints upon the .jacket 3 of the impression-cylinder 2 an impression the reverse of the form carried by the lower printing-cylinder, andat each turn of the cylinders this impression, carried by the jacket of the impression cylinder, comes against the lower surface of the web opposite the form upon the upper printing-cylinder and becomes transferred to the lower surface of the web in reverse of the impression thus brought around by the impression-cylinder, thus printing both sides of the web. As the jacket of the impression-cylinder received an impression in reverse of the form on the lower printing-cylinder and as that impression reversed itself in becoming transferred to the under surface of the fabric, it is obvious that the under surface of the fabric receives an impression corresponding precisely with the form on the lower printing-cylinder-thatis to say, unreversed. As the two sides of the fabric are to be printed in reverse of each other, it is obvious that the two forms, the one on the upper printing-cylinder and the one on the lower printing-cylinder, must be exactly alike, the upper form imprinting itself in reverse upon one side of the fabric, while the lower form sends its impression to the lower surface of the fabric through the medium of two reversals. In case the lower surface of the fabric was printed direct from a printing-cylinder, as is the case with the uppersurface, itis obvious that the two forms would require to be the reverse of each other, thus involving great skill in the production of the forms; but in the present case the two forms are identical with each other, and no skill is required in securing proper correspondence between them. The two forms, identical with each other, being secured to their respective printing-cylinders, it is only requisite that the two forms be so angularly adjusted upon their cylinders as to secure proper register. This may be done by angularly adjusting one cylinder with reference to the other or by angularly adjusting the form upon one of the cylinders. The drawrolls 9 having the same diameters as the printing-cylinders, it is obvious that if the fresh printing upon the web causes a set-off on the draw-rolls such set-off will impress itself in proper place upon the web in correspondence with the printing thereon, and thus do no harm. In the example given-that of the stripe part of the American flag-both the printing-forms would be supplied with red ink; but it is obvious that the system lends itself to printing with varying colors upon the opposite sides of the fabric. Thus, for instance, the upper printing-roll may be inked red and the lower printing-roll be inked blue, thus printing the upper side of the fabric in red and printing upon the lower side of the fabric an accurately-registering reverse impression in blue. In the American flag, as an example, there are two colors upon each side, being thus an example of multicolor printing. If the cylinders of my improved press, as represented in Fig. 2, are to be employed for producing one of the colorsas, for instance, the red portion of the American flag-then the blue portion will be produced bysubsequent subjection of the running fabric to a second similar series of three cylinders, the two printing-cylinders carrying the forms precisely alike and suited for the blue work, and similarly the web may be subjected to the action of as many such separate series of three cylinders each as there are colors to be produced upon each side of the fabric, this method of multicolor printing by running the fabric through various sets of printing-rolls in succession not being new.

I will now describe an improved construction for the printing-cylinders adapted for the printing of longitudinal stripesas, for instance, in the American flag.

Referring further to the drawings, 10 in Fig. 4 indicates a strip of fabric printed with the red stripes of numerous American flags of various sizes adapted to fill up the fabric; 11, the largest flag of the series upon the strip, the length of this flag being less than the circumference of the printing-cylinders and its width being less than that of the strip of fabric,-three repetitions of this flag appearing in so much of the strip asis shown; 12, a transverse series of three small flags, their combined widths equaling the width of large flag 11, and the length of the small flags 12, plus the length of large flag 11, plus the space between their ends, corresponding with the circumference of the printing-cylinders,there thus being a group of the small flags 12 interposed between each of the large flags 1 1; 13, a longitudinal series of three mediumsized flags disposed alongside the previouslymentioned flags, the length of this series of medium-sized flags, plus the spaces between them, corresponding with the circumference of the printing-cylinder and coming even endwise with the group represented by the large flag 11 and small flags 12; let, a space transversely across the strip of fabric between each complete group of flags, by complete group being meant a large flag 11, three small flags 12 at its end, and three medium-sized flags 13 alongside the large and small flags, each of these groups of large, small, and mediumsized flags, together with the space 1& between them, representing the circumference of the printing-cylinders and being repeated on the web at each turn of the printing-cylinders, and 15 the fields or unstriped portions of the flags, being the portions which are to receive the blue printing.

Referring to Fig. 4, assume, first, that only the large flags 11 be desired. The length of such flag is less thanthe circumference of the printing-cylinder. Henceaspace corresponding with the length of flags 12 would be wasted in the operation of printing. Side wastage may of course be avoided by usiuga strip of only needed width; butto avoid wastage between the ends of the large flags the small flags 12 or any other matterof suitable size are printed, and for economy in time and labor a wide strip is preferably used and flags printed alongside the large flags. With a printing-cylinderhavingacircumference and length suited to a given very large market size of printed flag it will be found that this dimension of printing-cylinder well lends itself to division after the general manner indicated in Fig. 4 to the printing of smaller market sizes without waste of printing-space upon the strip, and the same principle of division may be followed in connection with articles other than American flags.

Proceeding with the drawings, 10 indicates the shaft of the printing-cylinder, which will now be spoken of in the singular, as the two printing-cylinders become duplicates of each other; 17, the bearers of the printing-cylinders, having the form of disks fast on the shaft; 18, three disks secured upon the shaft of the printing-cylinder and having a diameter equal to that of the bearers 17, the peripheries of these disks forming printing-surfaces and their widths, spacing, and disposition on the shaft being in correspondence with the three long stripes of flag 11, (seen in Fig. 4;) 19, four similar disks upon the shaft corresponding in width, spacing, and position with the four shorter stripes of flag 11, these disksbein g preferably separately strung upon the shaft of the printing-cylinder and properly spaced apart by collars or hubs; 20, cut-away portions in the peripheries of disks 18 and 19 at points where no stripesare to be printed by those disks, the bottom of these cut-away portions being concentric with the axis of the disks and their lengths varying according to circumstances, the length in disk 18 being represented by the length of flags 12 plus space 14,as seen in Fig. 4,while in disks 19 it is represented by the length of flags 12 plus space 14 plus the length of the field in flag 11; 21, printing-plates secured to the bottoms of cut-away portions 20 of disks 18 and 19, the outer surfaces of these plates being circumferentially even with bearers 17 and the printingsurfaces of the disks, these printing -plates corresponding with flags 12 of Fig. 4, there being a separate plate for each of the three flags 12 or one plate for the three, as desired; 22, three printing-disks strung upon the shaft and corresponding in width and spacing with the three long stripes of flags 13, (seen in Fig.'

4,) these disks forming the long stripes for the three flags of the group 13; 23, a bolt extending through the bearers and disks of the printing-cylinders and serving to dowel the parts in proper angular position; 24, four printingdisks upon the shaft in correspondence with the short stripes of flags 13; 25,

cylinder; 30, a ratchet-wheel on an end of the reel-shaft projecting from the end of the impression-cylinder, which projecting end is secured for convenience in turning the reelshaft; 31, a bolt engaging the ratchet-wheel,

and 32 the exemplifying transmitting-gear ing of the system, consisting of a receivingpulley communicating motion by spur-gearing to the cylinders and draw-rolls.

Referring to Fig. 2, in applying the jacket 3 to the impression-cylinder 2 one end of the jacket is hooked to one series of spurs on the reel-shaft 28 and the reel-shaft partially turned, after which the jacket is brought ing system, a space on which there must be a blank or non-printing space on the printingcylinders. Referring to Fig. 4, this space is utilized at space 14, disposed endwise between flags. Whatever may be the relationship of the various flags of the groups, otherwise none of them are to cross the space 14. The blank space 14 may thus serve as the stick-space for all the flags contiguous to it.

Comparing Figs. 3, 4, and 5, it will be observed that all the stripes of the large flags 11 and of the medium flags 13 are printed by means of the disks and that the small flags 12 are printed by means of printing-plates secured in the cut away portions of disks employed in printing large flags. The space represented by flags 12 and the printing-plates which produce them may of course be filled up with printing-plates suited for articles other than flags or, if waste be ignored, may be left blank. The

disks

22 and 24 for flags 13 may be removed or may be replaced by others suited for other dimensions of flags, and printing-plates may be used in conjunction with them or not, as desired. Printingplates 21 may be removed and changed without disturbing any disks.
