hncwn'that Tricia-is Frown Ens-I asrdijec't er the King of Great. T11. residingat Leeds, inth'e county of e England, he e invented certain i N and useful.Improvement-s, in Rotary .Printnag-Machines, of which the following 't'iil-i. clear, and exact description.

ion relates 0O improvements in; presses and rnore especially t we which comprises printing surupon the peripheries of threerc nting 'cyiinders which can he no 1. id out of contact 'ith each in which the second or transfer furnished with two or more surfaces -which receive their own 10. in designs from-the design or plate 'ider without super pr'in'ting and transfer-thesein sequence to the sheet or impression surf-ace carried by e-n' impression cylinder. A rotary printing press of this type siwwn and described in Letters Patent iio. 41 84. I invention in'this instance consists in on T ronedconstruction which comprises s-uhs' toting tor'tn'e design or plate cylinder of snch a machine, two or more cylinders each furnished with inking and. damping rollers, according to the nature of the design tri ace carried thereby, e'ach'cylinder being 1 51 printing con-tact with a transfer cylinder or wholly removed therefrom. The design cylinder-s may he of smaller diameter than the transfer cylinder and are tirei erahly a suhinultiple thereof, corresponding to the ninnber of spaces or printing surfaces on the periphery oi the transfer cylinderor corresj'v'ond ratio with the number of spaces or printing su-rfaces'on the rensfe'r cylinder to the number of design surfaces on each of the design cylinders. T he number ofdesig'n or plate cylinders depends upon the number of colors 01 designs which it is desired to print upon the sheet.

The invention also consists in'the combi- 'nation and construction of parts set forth in the specification and claims appended hereto. i

In thedrawings, Figure 1 is a diagram natic sectional view through the cylinders ota rotary press constructed according to *t-he invention; Figs. 2 and 3 are simi'lar wiews showing modifications. awnefernn first to Fig. 1, the cylinders 1 '1" are of equal diame er and ere each:

- diagrannn-ati'cally and are of the Well known type. If the machine is used tor ietterpress printing, a plate of the stereotype form maybe used, in which case the demoing' roil-ers 5, I)" are not required. The-icy?- ind'ers l. 1 are mounted on eccentric hearings 7, 7 so that the design surfaces or plates carried thereby may be nioyedbodily into'and out of contact with the peripheral printing sin-faces of the transfer cyiinder 8. The cylinders are moved by any snitahie mechanism (not shown) so that the design SHIfRCG or plate 2 will only he impressed'on the. printin-gsurface'tiof the cyiinder 8 and the plate '2 only upon the printing, surface 9. The printing surfaces 9 and 9 are'simi- 'lar to those used 1n the .petent above re terred to and consist of blanket-s. made of rubber or the like which areadeptetijto'fr'eceive the impression trom the design ismface or

plate

2, 2 revolution and transfer it at each revolution 'to the sheet to be imprinteth'which is hastened to the iniprer surface 'or blanket 10' when a sheet is not carried by the impression cylinde r'cn that 'ievolnticin shown in the pstent'above' referred to,' the cylinder 8 they be moved into and out of contact with. the cylinder 1. 1 and the impression cylinder 1O. The sheets to he printed ere fed from a table 1'1 and are seized by grippers 12 which are of any welt known construction and m'ay io'e -.provided with'any well known mechanism torautomatically releasing the printed sheet, so that it may be removed by the takeoff mechanism 13, and for automatically seizing the next sheet to beprinted. It is also well known how such a mechanism may be "arranged to cause grippers to se'izer a sheet at each revolution or at a secondor third revolution only if desired.

Fig. 2 shows a modification in .which'there are hree design cylinders '1, 1-, 1 lsp'a ce'd tor cooperation with the transfer cylinder- 8 carrying a like number of printing sur- 't-a'c'cs 95:93 n is on notedthat with.

"ion cylinder '10, or to the printing not a prime number, 1%; is better to provide each cylinder Willi more than one printing surface so as v reduce ihe number print-- ing cylinders required.

Fig. 3 shovs that form or modification in which there are four design su ac 52 2 carried by two plate cyli" ,d-ers .i and 1, each cylinder urryiug two design surfaces. 'lhe iran 1' cylinder 8 carries four cooperating or iransicr surfaces 9, 9, J, and 9 each of: which is adapted to cooperate with only one of the design surfaces. it is to he noted ilusrefore that the cylinders l, 1 are mounted to he moved into and out of contact with the transfer cylinder 8 in nu h a manner that the

These modifications are each adapted to he used in the various Ways set out in the parent before referred to; for printing siziuiliaucously on hoih sides of the paper will: either the same designs or colors, as is necessary in transparent work, or with dillerent (h ns and colors; by feeding a sheet of illiil illfil for each revolution of the impression cylinder, the press may he used to printt'ue same designs on a like number of sheetsas' there are surfaces on the iransfer cylinder, one for each revolution of the impression cylinde r'so increasing the outill: of the press to any desired degree; the press may also be used for printing two, three, or more designs or colors consecutively .on the same sheet by retaining the sheet oil" the impression cylinder for one revolution of the transfer cylinder, inwhich case each of the printing surfaces will he transferred to the sheet in turn dependihg' side simultaneously. By properly feeding the sheet, negative plates may he used on some of the design cylinders which Will in turn be iranslieri ed to the blankets of the irans cylinder and impressed upon the hlanl cl the impression cylinder which will gire'thc correct design on the inside of l'hc sheet carried thereby.
