BFWFIM-UIIOIW forming part of Letters Patent No. 719,324, dated January 27, 1903.

From the above description it will be seen that the two surfacesv of the auxiliary web are used and a single web serves for both sets of printing mechanism, the auxiliary web being finally rewound into a roll.

I have described my improvements in detail, but wish it to be understood that I do not limit myself to the specific details of apparatus shown, as my invention includes equivalents thereof.

That which I claim as my invention, and desire to secure by Letters Patent, is-

l. A printing-press having a plurality of sets of web-printing mechanism, an auxiliary web, means for conducting said auxiliary web through a plurality of said sets of printing mechanism in contact with the printed surfaces of the printed webs, and rewinding mechanism, said rewinding mechanism being arranged to rewind the auxiliary web upon an axis parallel with the cylinders of the printing mechanism, substantially as described.

2. A printing-press having a plurality of sets of web-printing mechanism, an auxiliary web, means for conducting said auxiliary web through a plurality of sets of printing mechanism without turning said web, and rewinding mechanism for said auxiliary web, said rewinding mechanism being arranged with its axis parallel with the axes of the cylinders of the printing mechanism, substantially as described.

3. A printing-press having upper and lower sets of web-printing mechanism, an auxiliary web arranged between said sets of printing mechanism, means for conducting said auxiliary web, without turning, through said upper and lower sets of printing mechanism in contact with the printed surfaces of the printed webs, and rewinding mechanism, said rewinding mechanism being arranged with its axis parallel with the axes of the cylinders of the printing mechanism, substantially as described.

4. In combination, a plurality of web-printing mechanisms having parallel cylinders and each adapted for perfecting a separate web of paper, an offset-web, mechanism for guiding said offset-web into contact with each web of paper, an offset-web-receiving roll, mechanism for holding said receiving-roll of said offset-web with its axis parallel with said cylinders whereby the web proceeds without turning from the printing mechanism to said receiving-roll, mechanism whereby said receiving-roll is driven and means whereby the speed of said receiving-roll is adjusted relatively to the speed of the printing mechanism, substantially as described.

5. In combination, a plurality of web-printing mechanisms having parallel cylinders and each adapted for perfecting a separate web of paper, an offset-web, mechanism for guiding said offset-web into contact with each web of paper, an oset-web-snpply roll, an osetweb-receiving roll and mechanisms for holding said supply and receiving rolls substantially between two of said mechanisms with their axes parallel with said cylinders whereby the offset-web proceeds without turning from said supply-roll to said receiving-roll, mechanism whereby said receiving-roll is driven and means whereby the speed of said receiving-roll is adjusted relatively to the speed of the printing mechanism, substantially as described.

6. In combination, a pluralityof web-printing mechanisms,having parallel cylinders and each adapted for perfecting a single web of paper, an offset-web, mechanism for guiding said offset-web into contact with each web of paper, an offset-web-receiving roll, mechanism whereby said receiving-roll is driven and means whereby the speed of said receivingroll is adjusted relatively to the speed of said printing mechanism, substantially'as described.
