Fig. S is au eemvti'en of a Cylinde showing another Way in which emi spaees, m paia,

are 1er e may be applied showing sew" to printing cylinder upon which one or more segmental intaglio printing plates 1l,

are to be placed. When applied toa cylinn der or mandrel, these plates are of curved laces 12, as indicated in Fig. 7, to hold the intaglio printing plate in position.

.The form ott the invention shown in the lirst six figures represei'its a cylinder adapted to takeplates ot varying sizes. It is practicable to arrange to have the printing plates of definite or standard dimensions, as for example, ten, tvvelve, fourteen and the Width of the plate longitudinally of 'the ve'vlinder may be varied, either in standard dimensions or otherwise, desired. Accordingly, clamps preferably are kept in :fo elfe the )rinting plates are lili-ely to have. These s may be held on the cylinder in any red ".vay. The drawings illustrate a prered construction tor this purpose Consisting of slots 15 extending along' the cylinder and "i y'ing enlarged openings 16 at their ends. lnese slots are located at intervals around the cylinder and are adapted t'c receive fr needs li' with which J" vvided. These heads may be secured rigidly to the clamps so that they may be put into the openings 16 .to guide the clamps properly up to the plate, or they may be removable. ln 'the latter case, the clamps are fixed in position by means of screws 18 which sore-iv into the heads 17 and tighten them the under sides of the T-slots l5. n the heads are integral the screws are ed position.

or( er that the doctor blade 19 may over the intaglio plate in the usual r and clean the furniture, preferably '..out passing from` a surface of one .t to a suriface of another height, the cramps are made exactly high; thatis, the clamps'and printing plates torni one continuousv cylindrical surface. ln the saine to uw, Wed shaped filling pieces Q0 Which :d at both endl of each printing cured in po. `on lin any usual instance by means of bands 2l) high. 'r The ends .of the cleared in any Way, as by flat segn'iental form so as to lit the cylinder andf-.Irteen inches long, it being understood that vcylinder in vthis Way,

et the dili'erent standard widths which parallel longitudinal T-shaped.

trie clamps are pro.

emoloyed for securing the clamps in ad-V headed screws '22 passing through slots into blocks 23 on the cylinder. `When the cylinder is used in this Way for a small plate on a large cylinder, a straight segmental back piece 26 is employed also exactly of plate height. This' piece is securely xed inposition by screws entering counter-sunk openings in the back piece or in any other convenient manner. These parts are.`made up so as to entirely surround the cylinder and form a complete cylindricall surface so that the doctor feet, smooth, uniform, continuous, surface throughout its travel romwhichit may remove all ink, and 'by which it subject to any of the changes of tension above mentioned. Alt Will be seen'that this will not be result is obtained simply by the use of uni- ,Y

the furniture and replaced at will.; lnordei".

to use one ormore small plates upon a large it is necessary only to have the clamps "of the same length as the plates o r if theyare shorter 'to lill in with other full height pieces 25, and tolhave' the filling strips as'long as the plate may happen to be Wide. Whatever may be the Widthof'the plate tobe run, the opening' of the fountain is usually madey atrille shorter so that no ink shall be suppliedA much beyond theedge's of the. plates. In this Way, there is no excess of ink at any v-of the' sides to cause smud ing. v.

The descr1ption so far given relates chiefly to a cylinder for a press adapted to take plates of varying size for use in job printing.

In order to take plates of a standard uniform size for use by the newspapenbook or periodical printer, a slightly dillerent construction is preferred, although the saine invention applies to it. In this case, reference being had .to Fig. 8, straight filling pieces 30 are employed corresponding to the margins which run transversely to the web. These are secured to the cylinder. Laterally adjustable clamps 31 are employed in c0n neetion with them. These maybe adjustable along T-slots 32 by means of heads and screws 33 in the same manner as above or in any other-desiredway. For the center longitudinal margin, clamps 35 are preferably used xedto the cylinder in any convenient Way. These clamps have beveled edges like the clamps 13 and all the clamps and lilling\ pieces are so arranged as to permit cleaning by the doctor blade, preferably being plate high, as described above. By this arrangement, if the plates are made a given length s0 that they lit between the straight filling. pieces, thejclamps 3l can be brought up to hold them in position.

Thus, the entire surface of the cylinderis smooth and continuous as in the .other case,

as if it were actually made of a continuous shell and thus itis ossible to print successfully from a plurality of intaglio plates associat'ed together upon1 a single printing member.

The' only idiiiculty 'with constructions made as aboye described, is that there may -be thin cracks or interstices between the plates which *cannot lbe entirely removed by any accuracy ylof fitting. These under v some circumstances willprmtiine hair like lines, which .upon ,ne work ma be objectionable as the doctor blade 'will eave ink in them. In order toovercoinethis difficulty these cracks are lled properly p repared cement, Wax, or similar preparation .g after the platesare in position-and then are quickly rubbed smooth so that as soon as the cement hai-dens, which will require but an instant, no interstices exceptn of the designs, will remain to accumulate ink. This is indicated in Fig. 7 where thev minute space between the plate 1l andthe clamp 13 is .lled 'with vthe cement' 41. 'The screwheads'may be treated in the same way..

Itwill be seen that this invention whether carried out in the particular ways set forth or yiin any other way within the scope of theV claims, provides means whereb one or more I i. intaglio plates may be mounte upon a plate j cylinder or carrier in-sucha way that intagliol printin 'periodical wor as well as on Job presses by. 40

taglio printing facility `equal to that with which relief printmay be accomplished with -ng is now done and the line results of inobtained in newspaper and convenient and inexpensive means.

When the invention, or vany part of it, is

- applied to flat plates, which may easily be dancin substantially the manner described,

they-are held on a support in a similar manner Aannd the furniture is arranged in substantially the same way, preferably being -smooth and plate high.
