sub-'presses,.s howingthe one on the right in 5 To this end my invention consists in the construction and arrangement-of the various parts, as more fully hereinafter described, and

pointed-out in the claims. Figure 1 of the drawings annexed gives a is a cross-section of Fig. 1, between two of the end elevation. Fig. 4 isa detail of theprintbig-cylinder. Fig.5is a sectional view, showing three press-frames boltedtogether.

lu -Figs. 1 and 2 of the-drawings I have shownthe machine as composed of two submachines connected bya conveyer, and form;

ing one complete or compound machineadapt ed to'print two colors, and in Fig. 5 I have printed.

shown .three presses bolted together and'forming a compound press adapted to print three colors; but any number of sub-machines may be combined together in the same'manner, according to the number of colors desired -to be A A indicate the sub machine's, which are of similar construction, as maybe observed.

These consist of sustainin side frames 43 a i isni tabl y shaped and ri gidly joined by-cross rods.

or braces in a substantial manner. Between these side frames are mounted the type-cylin- I d'erb and impression-cylinder c, whichare of similar diameter and'closely approach each other, the one being placed directly over the other,'as shown. The journals of these cylinders revolve in movable;- or adjustable boxes set in slots in the side frames, as illustrated in Figs. 1 and 2, and are positively geared togetherin the manner of rolls, as showuin Fig. 3, 'so as to revolve in unison."

The inking mechanism of each press is. placed directly over each type-cylinder. This consists of an ink-fouutain, e, of ordinary form,

mounted on standards rising from the main side fra nes,'as shown bestin Fig, 1, and carrying an adjustable ink-knife, which rests against an iron roller, f,'turning in the-ink in the direction shown, and revolving against thecom position rollerg, which revolves'against alarger iron roller, h, from which the film of ink becomes distributedto a second com-posi-I tion roller, g, thence to two iron rollers, h,--

and finally to three composition rollers, 9,

which roll against'the top of the type-cylinder and ink the form thereon. This arrangement of inking-rollers, as maybe observed, insures a thorough'and even distribution of the ink and a perfect inking of the form, and the whole series of ink-rollers, together with the type and impression cylinders, are thus placed in vertical columns, which isboth compact "and convenient.

'The inking-rollers, as may be observed, are

mounted in a frame which surmounts the main frameot'the press, and consists of two inverted-T-shaped standards, i i, joined by stayrods on one ot'which the frame is.

hinged to lugs It on the top of the main frame,

so that when set-screws k on the opposite side i are loosened the frame, with its series of roll-.

ers, may be raised and swung back, as indicated by the dotted arc so as to allow the removal'ot' the type-cylinder from the frame, as

will 'behecessary to allow thedisplacement and setting up of the forms thereon.

It will be readily understood from Fig. 1

that the journal-boxes of the type-cylinder are movable through a slot in the top of the frame to allow of such removal of the cylinder, and that'the boxes are held firmlyin position therein. when replaced by anadjustable'sct-screw,

l, working through a removable plate or bar, 11', temporarily fixed over the slot. Now, the composition rollers of the inking mechanism,

which in Fig. 1 are indicated by heavier lines,

are free to rotate but have no end motion in their bearings, whereas theiron rollers h h are'also free torotate, and have an e'ndwise vibration imparted thereto for. the purpose of effecting the more perfect distribution of the ink, as is usual. lhe lower (or pair of) iron rollers, h h, are therefore mounted in a frame, m, havingacentral journal'orrod, which passes through a guide bos in the vertical slot in the ICQ standards as shown in plan in Fig. -2 and elevation in Fig. 3, and which isprolonged atone end to connect to one arm 'of' a leveI 3..'n, Fig. 3,'the opposite arm of' which connects'to 5' the, journal of the upper iron roller, h; This lever is actuated by a smaller lever, n, which is vibrated by a cam, 0, on" the gear-wheelofthc,type-eylinder, so that when the press is in action the upper and lower iron rollers are vibrated 'to and fro inopposite directions simultaneously with their rota-tion,-for the purpose already stated. I prefer'to have the cam 0 4 formed with an odd number 'of changes, so that the vibrations of theiron rollers will not occur constantly at the same relative points of the other rollers, whereby the ink-distribution is thus rendered more perfect.

It may be finally noted that the severalink i'ng-rollers are mounted in arsnperposed series in the vertical slot or slots of theirframeyand that the whole series are pressed to theirwork by the screwsp 1;, bearing upon the box o f the' uppermost roller, so that, by; loosening this screw and removing the top bar, p',-the whole set ot' rollers may be easily removed or re placed, as occasion requires; and this con-r struction, as will be seen, emhodiesfboth simplicity-and convenience. A It may now be noted from Fig.1 that th '0 sub machines are so relatively arranged that the distance between the centersofthe two type and impression cylinders is just equal to i the circumference thereof, that these cylinders.

are placed onthe same plane, and that the 5- framesot' the two machinesare joined byscrewbolts g, by adjusting which this distance may beexactly regulated. Noiv fixedto each im} pression-cyiinder, or forming partthereof, are two chain-wheels, r 1*, (see FigsLl and 3,) which.- -4d are arranged near either. end; ot' the cylinder,

just at or outside the margin of the, form on, the type-cylinder, around which wheels endless metallic chains 8 pass from cylinder tocylinder, as shown best in Fig. 1, thetop edge of these chains being in true plane with the junction-line of the cylinders. On theextreme: cndsof the type and impression cylinders rims or bearers b, c,of similardiamoter,arforrhed,

Within these rims the diameter of each cylinder is slightly reduced for a short distance, and within these reductions on the type-cylinders, and occupyingthe w main central part thereof, is fizredfthefform."

'The space on the im'pression-cylinder-corre spending to the form-space on the'typeicylinderis of slightly less diameter than the diameter ofthefo'rm, so as to allow of one or more windings of paper or other packing tad-make an elastic surface to receive theflmpression and to allow of the (make-ready? or packing patches, corresponding to the light and heavy 5 portions of 1theform,-so 'as to produce aperfect print, as will he 'readilyainderstood by printers. f

The sheet, as may be now'ob- 7 served, passes through the machine in a conthe commencementof operations that the sheet has been properly seized by the chain and has entered between the first set of cylinders,and that the initial points of the forms on' each cylinder are in the same relative position and coincident with thejunction line, itwill therefore be seen that if the press is-now set inmotion the. impression from the firstcylinder in y the first color will be made onthe entering" sheet, and-the sheetqwillthence advance to meet the second cylinder, at which it'will arrive just in ems to receive the impression in. the second color'in perfect register with the first, and while-this second ilnpression'i's being made thefirst cylinder makes'asecond int-- pression in the/firstcolor, and soon constantly.

Another important feature of my improved press consists in the hollow suction table or box a, arranged between the chains 88, and

'ezite'nding between the "imprssioncylinders as close aspossible to the junction ofthe-same guarantee cheap, 7

with the type-cylinders, as show'n "inside-cla vation in Fig. 1 and cross-section in Fig; 3.v

The top of this box is flush with the top; edge of the'chain and with'the'j-uuction-line efthe -cylinders,-- and is extensively perforated,*fas

shown in Fig. 3, and over this'perforated top the sheet is drawn by the chain as it passes.

from one setof rollers to the other, as seen'in Fig. 1. a p

From the bottomof the box apipe, 'w, extendsto a. suction-blower or other exhausting device, whereby the air is drawn from thebox,

causing a suction on thesheetL which holds it flat and level and preventsiall puckering or fluttering in its passage between the rollers, and thus insures a perfect .feed of the paper thereto. Fnrthermorathe suction-on the sheet holds it downfirml y on the spikes of the chain and prevents it being raised from thesame by the adhesion of the ink on the first type-cylinder when rotating from .thes'heet after making the impression, as would be otherwise liable to occur.

In the drawings I have shown the chains 8 s asserving both as the. conveyers of. the'sheet from press to press, as well as the positive t-lriving connection which operatively couples the presses; but it isthought preferable to einploy distinct driving-gear to operativelyl couple the presses, leaving the chains to serve chiefly asthe sheet-conveyer, as machinists will readily nnderstand.-

- I The form on the type-cylinders is'preferabl y madehp of stereotype-plates g-y, (see Figs. 1 and 4,) made in sections, screwed to a cylinder or cylindrical ring of lead or soft metal, 2,

which is filled into a recess formed in the middle or form portion of the cylinder, as shown clearlyin said figures, the cylinder of soft metal being turned ofi true and less than type or printing height, and the-plates accuratelyv "fastened thereto, so as to form 'a true cylindrimetal, which can be readily drilled at any cal printing-surface of' full printing height. By thismeansthe priptin'g'plates are screwed directly to the metallic surface of the printing cylinder; and the entire faceof the cylinder for receiving and supporting the plates iscomposed .of a cylindrical layer or facing of soft point, and which will readily admit and firmly hold a screw' when screwed intoa tight-fitting hole bored therein. Hence the thin printingplates yy, making up the form can'be readily bentto the proper curve to fit upon the soft metal face of the cylinder, and holes may then be drilled through the plates and intdthe'soft metalfacingof the cylinder, (see Fig. 4,).after which short "screws can be screwed into these holeswith arr ordinary screw-driver, thus affixing the printing plate's onto .the fo'rm-cyli'n der at any desired position in aquick and sin plemode and iua perfectlypositiveand fixed of-all'detachable-cla ypsi Wedges, or. other manner, which pre'ventsthe possible displacement or detachment of the plates when the press is in action, and thereb'y'obviates the use usual fastening devices which are liable-to get .loose. 1

The soft-metal facing has the followingafdvantages over one of .h.ard metal: first,it; is

mist" t a mueh.,cheaper,;-beeanse although,if preferred, it may, 'as'above stated,'be turned off after it is filled intoth'e recess, yetit isobviousthat the iron cylinders maylbe placed in suitable molds and their facings east thereof: of ,the 'right size, requiring no-further fitting or other work to m ake them ready for the reception of v the plates z second, the facing can'be much more readily drilled; third, by using a drill, and screws of ,the proper proportionate sizes,

no tapping of the holes is necessary, as screws can be screweil into soft metal with an ordinary.

screw-driver without tappingthehol; fourth, the holes can be readily filled up by running melted 'solder'into thennor bydriring ina-- plug of lead and soldering it, should the old holes be found to be in the wrong place when" putting on a new plate of a slightly difi'erent size. The' second and third of these advantages would be found also with a wood facing; butif wood were used the holes, after being used a few times for different plates, wouldfbe worn out and would not hold, and plugging saidholes would be of little 'or no use, whereas with soft-metal facing the holes could be readily plugged, and then-.thc plugs soldered fast. 'As compared with wood facing, a metal facing would" have the further advantage of 7 -'not shrinking, swelling, or warping-under the varying states of the atmosphere ,or dampness due-to the washing of the plates. It will be also seen that-by-tnaking the soft met'a'l facing of partial printing height, and having thestereotypepla tes-of the remaining thickness to form the full printing height, tlie"stereotype or printing plates are'rendered'thin and light,

loo

res

and are much more ctrsilghandled and bent to the curve of th'e'cylin'dier, auda much-less amount of metal is required 'to' be, melted,

molded, and renielted. in making and reducing-tare the plates, which'greatlyfacil'itates the work:

. 'Iulieu of' the spikes onthe chain to seize.

the margins of the paper, asu'itable form of Q spring-jaw may, be used'to-grasp the margin,

and in lieu of the jointed chains themselves flexiblesteel or metal bands may be used.

I have shown the hollow perforated air chamber or table w as placed beneath the sheet and acting to hold the sheet down by the i suction caused by a partial vacuum inthe box; but in some cases this may be reversed, the "hollow'boxi being placed over the sheet and air forced into the same to produce a blast or air pressure against the sheet; to hold it flat against a table placed beneath it. The arrangement shown is,-.howe'ver, preferable. Y

1 am aware that cylinders coated "with-soft metal have been used in printing to-rece'ive stripsof 'm etal' driven into said soft met ls 1n theEnglish PatGDt'N0. -3,322 of 1810; but

in such case neither stereotype nor any'other' fOTmf of prin tingflplates were employed. ,To 7

and before the same or another printing-sun:

face could be employed on saidcylinderit was necessary=not only torepair or recastthe sott metal on the-cylinder, but to compose anew printing-surface or recompose the-old oneand drive it into -the cylinderstrlp by strip. In

' .my plan, on the contrary, the same'plate may l. A compound printing-machine composed be easily removed-and as easily-replaced again and again without 'recomposition, or a different plate ,may be readily used on the same cylinder in the intervals between the use of the other plate without any repairing or recastin g ofthesoft'metal.
