Letters Patent N 96,480, dated November 2, 18,69.

IMPROVEMENT In PRINTING-PRESSES.-

Thc Schedule referred to in these Lettar'Patent and making part of the same.

To Il whom i t may concern Be it known that I, JAMrasN. PHELPs, ofthe city of Brooklyn, in the county of Kings, and State of New York, have invented certain new and useful Improvements in Printing-Presses; and I do hereby declare the following 'to be a full, clear, and exa-ct de` scription of the same, reference being had to the accompanying drawings,ibrming a part of this specification, in which- Figure l is a plan view of a printing-press, constructed according to my invention.

Figure 2 is a longitudinal vertical section same.

Figures 3 and 4 are detail views, hereinafter fully described.

Similar letters of reference indicate corresponding parts in the several figures'.

rllhis invention relates to the inking-apparatus, and its object is to ink dill'erent parts of the length and width of a form of type at o'ne operation, with ink of differentcolors, for the purpose of producing, by lone impression, a printed sheet, different lilies or parts of of the ,which are printed in such various colors as may be desired.

To'accomplish this, the ink-fountain is divided transversely into, or otherwise made to consist of a number of sections or compariments', corresponding with the number of variously-colored lines or parts desired to he produced on the sheet, suoli compartments being severally of widths corresponding wit-h thc diercnt lines ot' type, or dilerent parts of the length '0I-width of the form, which are to be inked in dicrcnteolors, and severally filled with ink ofthe desired colors. I

The distributing, carrying, and inking-rollers are made in sections or sets, corresponding in length with vthe width ot' the sections of the ,ink-tinnitain, and so suitably arranged and operated that while all operate simultaneously, one section of each or-one set may operate in connection with one section o1' compartment of the fountain, to take the ink therefrom and ink the portion or type-line, or any number of typelines, ot the forni arranged opposite to that section or compartment of the fountain.

rlhe invention consists in an ilnproved distributer, by which the traversingl or vibrating movement of the dislributcrs colmnonly used is dispensed with.

it further consists in a novel arrangement of the hed and type-cylinder of the press, and mode of opu eratin g the impression-cylinder, whereby the c0nstruction ot the press is simplilied.

To enable others skilled in the art to construct and operate my invention, I will proceed to describe it, having rch rence to the drawings.

l A represents the frame, supporting the several stationary and movable parts of the press.

'.lhe bed B is supported on one end on a hinge or owh* joint, B', and on the other e'nd, at each side, by a re eiprocating inclined plane, K.

The. two inclined planes KK are attached to a frame, P, having two pallets k J, arranged opposite each other, and in such 'relation to a revolving tappet or cam, h,'on the shaft i, that when the impressioncylinder is about to move over the bed of the press, the cam h. strikes the pallet k, and moves forward the frame P, and with it the inclined pla-nes K, which raise the hed of the press to a proper level, to receive the impression on the sheet which may be-on the cylinder.

In order to prevent too great friction in the movementof the frame, :four rollers l l, two on cach side, are placed under the frame, to snppo'rt its weight and lessen the rubbing-surface.

The impression-eylinder O has'bcariugs in a frame, D, which slides back andi'orth on parallel ways E E, situated longitudinally. one on'each. side of the press.

This cylinder receives a reciprocating motion by means of a pitman, G, attached to its axis, and connected to a crank, H, on the shaft This shaft is caused to make about one revolution to four of the driving-shaft; j, by a pinion, J, on the driving-shaft and spur-wheel I, on the secondarysha-ft i.

'lhe cylinder C has a spur-wheel ou each end of it, and each of these spul-#wheels gears into one of two stationary rac-ks R R,one on the inside ofeach of the parallel guides E.

This device is necessary to insure a perfect registering of -the form and cylinder, and prevent what is termed, in printers nomenclature, sl urring or sliding 0f the cylinder off the end ot' the form, s0 as to drag or extend the impression beyond the proper distance.

The form which is laid on the bed B'is inked by 'means of two deliveringor inking-rollersff, which have bearings for their axes in the. frame D, attached to the bearings'supporting cylinder C.

These rollers are arranged in sections or parts, on a polygonal or feathered shaft, as clearly shown in transverse section in figs. 2, 3, and 4, and the com position 1, fig. 3, is made in the. ordinary manner, and cast on a wooden or metallic cylindrical core, 2.

This core has a central aperture, 3, to fit the shaft or spindle s.

When a job or form is imposed upon the bed of the press, and the colors are agreed upon bythe pressman, these rollersV are put together on the. shaft s, in sections and spaces correspoxn'ling to the lines and spaces of type which the said sections are intended io ink or leave blank, the section of roller answering to aline or collection of lilies of type, and the space or spaces between two sections ranging with a space in the form.

The distributing-rollers o d o c and buntain-rollcrb -are put together in similar sections c, tl, and c, and

spaces d1 e.

Thedistributing-rollers e d c c revolve in bearings in the opposite end of the press-frame A fi-om that on which is situated the. driving shaftj, and thedeliv cringrollers ff receive ink at each time the cylinder c advances toward the distributors e, d, and c, when the rollers f j' rest fora short timelin contact, with the roller e, and receive their apportionmentof inlf'orihe inkingr of the form, preparatory to the succeeding impression.

'lhe i'ountain a is divided transversely into separate compartments a', to hold separately the several colors ot' ink desired, and ot' sntiicient capacity to hold enough ink for a Ljob, and these. compartments correspond in length tothe length of the cylindrical section of the rollers which are arranged in linetherewith.

These compartments of the fountain are kept separate by means of movable or adjustable partitionplates g, or the different compartments of the fountain may he made in separate lengths or box-like pieces, and the fountain-roller is similarly divided hy spaces corresponding with the other rollers, but. the spaces ot' thc fountain-roller should be ot' a much iess diameter than thoseofthe other rollers, in order that; the divisions in the fountain may be sufficiently high to prevent the ink from flowing from one apartment to another.

The distributers c c ean end view of a section and space ot' the latter one of which is shown in iig. 4, may he constructed ot' wooden cylinders c, covered with a felt or' leather exterior, e, as shown in tig. 4, and the interx'feniug,r space orseparator ci may he conveniently constructed of wood.

The distrihuter 1l has its hiking-surface ot spiral forni or construction, or is made like a screw ot' rapid pitch, either single or double-threaded, and carries the ink along the whole length of the distrihuters c c d e, and ohviates the necessityot a vibrating or traversing distributer, suoli as is commonly used, and which is operated by a double or cross-tlneaded screw, as'

v divided into sections or lengths 1l and spaces d', each corresponding with a similar space or section, arranged in liuc with them on the other rollers.

The entire series ot distrihuters receives a rotary motion hy means of a hand-pulley, M, on the. shaft ot' the distrihuter and endless hand ou., whiehpasscs over a pulley, j', on the driving-shaft j, and by the friction this distrihuter imparts motion to the rest of them.

Instead of having the inking-a-pparatus arranged transversely to thc length ot the press, it may be placed at right ang-lcs to the position shown in the annexed drawings, or at Veither side of the press, and

made to operate in a similar manner, but transversely over the hed.

This inking-apparatus may with equal facility bc applied t-o a printing-press with a reciprocating bed and a revolving cylinder moving on a lixed centre.

Vhat- I elailn as my invention, and desire to secure by Letters Patent, is

1. rlhe construction of' distributing-rollers d d with" spiral surfaces, substantially as and for the purpose herein set forth.

2. The comhinaiion 0i' the hinged type-bed B, th`e reciprocating inipression-roller C, and the. detached reciproea-ting frame 1, furnished with inclined plaines K K, the whole operating substantially as and for the purpose herein specilied.
