Be it known that we, RIQHARD M. Hon and DOMINIOK iitnoimnnm, citizens of the United States, I,th e said HOE; residing in the city of New York, county of New York, and State of New York, and Lthe said WnoKERLIN,residing in the city of Brooklyn, county of Kings,

and State of New York, hevejointly invented certain new and useful Improvements in Inking Apparatus for Printing-lliachines, fully described nndrepresentedin the following speeiii cgition uartile accompanying drawings, forming a pnrt of the ame.-

In said drawings, Figure 1 is a right-hand side elevationof so much of a printing-press as is requisite to illustrate the structure and operation of the presentimprovements. Fig.

is a similar view taken from the opposite side of the machine. Fig.3 is a longitudinal sectional elevation. Fig. i is a plan or top view; Fig. 5, an endelevation; andFig. 6 a. side elevation (reduced infs'c'zile) showing the inking mechanism in its two positions, one of whicl 'is indicated bydotted lines.

This inventionielzites ctoilet-bed printingmachines; and it eonsists in an ink-distributing apparatus arrangcd'to distribute ink in twoseparate courses to independent sets of form-rollers that apply it directly to the form without the use of a distrilnlting-table.

It also consists in mounting all of the ink distributing apparatus in a movable carriage and providing said eerriegewith means for reisjingnnd lowc'ri iig the sinus and for transferring fioin' end t the rinting position; whereby liesaidjnp'f isrendered capeble of .being removed f1 om tsjdpe'rative position infront ofthe inigires. err-cylinder, so as to expose the form-rollerssndenaole the same to beieniovednnd replaced withgreat facility and convenience. Inthe drnwings of this invention only so much oi the printing-machine is shown as is necessary toillustratetlieistrueture of the inkingflpperatusaudits cooperative relation to i th e yri ntingmachine;

Aswill be re'edily' understood, the ink-distributing apparatus is located in front of the ers are adj nsted to deposit ind distri bute-i nk upoii'the-formasitpilssesincontact-with their impressioncylinderfii), as'is common. Itconi sists of an ink-fountain, 10, in which revolves a metal fonntain roller, 11, the supply of ink to which is controlled by the usueldoctorknife, 12. The ink is transferred from this fountain-roller 11 to a continuously-revelving metallic distributing-roller,14; by an oscillating composition! takingrollenvwhm The ink thus transferred isixdistnibntedi upon the roller ding l roiler, 15. IFroint vi this distribntingrrolle bi thei nleistmnsferred y by a composition waking-roller, 16; ion large by a composition metallic distributing-cylinder, 17. Upon this i distributing-cylinder are mounted three riding composition rollers, l8, 19, and 20, the two former of which vibrate endwise and which serve to distribute theink evenly over the surface of the snid'cylinder 17.

The distributed ink from the surfiioe of this eylinder'17 is cara ried to separate vi'brating steel distributing i rollers 21 22 by xneensi ofntngo intermediate; composition rollers, 23 24; plaeedgat opposite.

27 28, which form-rollers 25 26 27 28 are mounted in adjustable bearings that are supunder surfeees in its reciprocziiorymovements.

engages with another interinediateflti'i, that;

meshes with a toothed wheel, 68', on the shaft y of the cylinder 17. The two'eteeliroilecs 21 22 and the central cylinder, 17,are thus driven by motion derived from a rack on the reciprocating type-bed, so that they and all the rollers in contact with them run forward and backward in unison with the type-bed, dur ing which. movements the inking-cylinder gives a supply of ink through the rollers 23 24 to each pair 25 26 and 27 28 of the formrollers. i

All the parts of the inking apparatus except the form-rollers 25 26 27 28 and the pinions 95 96 97 are mounted in a movable carriage, so that said parts may be hodily removed from: over the form-rollers, as shown in dotted lines in Fig: 6.. This frame-work consists of opposite side frames, 101 102, and suitable connecting-braces, in which side frames the various rotating parts are suitably journaled, as arethe pinions 66 67.

The fonntaintroller 11 is given an intermittent feed through 'ato'o'thed scgmennpawl, and

ratchet by 1i]8liDS.0fa bell-crank, 80, that is connected with smoking lever, 81, by a rod,

82, which lever 8i is vibrated at proper intervals by means of a push-rod, 83, that is operated by a cam, 30, on a longitudinal rotating shaft, 89.,in the usual manner.

The roller 13 is vibrated in one direction by alien-crank, 85, connecting-rod 86, and lever 37, which latter is vibrated by a push-rod, 88,

that is operated by a cam, 31, on the shaft 84,

and is; vibrated in the opposite direction by the springseated rod 35, attached to the rockarm 36. The-"roller 16 is vibrated in one direetion hy shell-crank, .89, rod 90, and lever .91, which latter isvibrated by "a push-rod, 92, actuated loy a cam,-32, on said shaft '84 and is vibrated in, the opposite direction by the springiseated' rod 3-7 fihe distributing'roller 14 is driven 'hya helt running from the pulley 103 to anotlie'r iipon any suitable shaftof the printing-machine, and said roller is given a vibrating motion endwise bymeans of a rightand-lefthand worm, 51, at one end of its shaft, which worm works with an oscillating fork in the well-known manner. The rollers 18 19 21 22 are caused to vibrate endwise by means of rock-arms 52 53 5455, motion being derived from a rock-shaft, 56, through cross-heads whose arms 57 58 have pins that enter grooved collars on the shaft of the rollers 21 22. The rock-shaft 56 is operated through an arm, 33, which projects from its lower end and engages with a grooved cam, 34, on the shaft 84. This arrangement of inking apparatus is such that it operates to distribute the ink very finely and that each pair of form-rollers receive from the large central cylinder the same quantity of ink, and as they give oif the ink to the form it is constantly renewed and equalized, the result being. that every part of the form is equally inked.

The ink supplying, carrying, distribgting, and ,conveyingrollers are supported in a inov- 'able carriage, so that they may, as already stated, he bodily removed from over the formrollers that the latter may be more easily put a 13-h... H

assess in place and removed and convenient access to the impression-cylinder afi'orded for the purpose of making ready its printing-surface, and this carriage is removed in the following manner: A shaft, 60, is journaled in the frame-work and runs across the lower part of the machine. It is supplied with a hand-lever, 61, at one end and at appropriate points within and near each side frame with earns 62, which cams operate the T- shaped push-bars 63, the upper ends of which stand just underneath projections of the feet 42 of the movablccarriage, bythe operation of which push-bars the carriage, when loosened from its swinging clamps 46 and clampscrews 44, may be raised a short distance. In being thus raised the gearing that drives the various rollers separates, the.

grooved collars on the shafts of the rollers 21 22 lift off the pins in the arms 57 58 of the cross-head, and the levers of the fountain and taking rollers leave their push-rods. When the movable carriage is thus raised, a

roller-frame, 40, is laid on each topv rail, 41,

of the machine, one at each side, which rolleri'ranies are-then run in under the raised carri e, as in Fig. 6, one such roller-frame then an erlying each of the feet 42 of the carriage. The top rail, 41, and the bottom of the feet 42 are each grooved to receive the guidingtlanges' on the rollers of the said roller-frame,

"so that when the carriage is lowered onto the roller-frame by a contrary movement-of the hand-lever 61 it will be supported in a condition to be easily rolled backand forth. When rolled back, as shown in dotted lines of Fig. 6, it will leave the form-rollers uncovered and give free access to the impression-cylinder, and will also permit the form-rollers to be removed, if desired.

To bring the ink'distributing apparatus into a proper position over the form-rollers to commence the printing operation, it is rolled forward into the position shown in full lines in Fig. 6. It is then slightly raised to free the roller-frames 40, the latter are rolled rearward from. beneath the feet 42, and the said ink-distributing apparatus is lowered by a proper movement of the hand-lever 61 until its said feet .42 rest on the side frames of themachine, as in Figs. 1, 2, 3, and 5, when .its;gearing,will, be re-engaged, the grooved collarson the rollers 21 22 will drop on the pins in the levers 57 58, and the levers 81 87 91 will again rest upon their push-rods 83 88 92. In this position the ink-distributing apparatus rests solidly in place, and is rigidly secured to brackets 111 and 112, projecting from the main frame of the machine, by means of the projecting portions of its side frames, 101 102, which carry clamp-screws'44, the shanks of which enter sockets in brackets 111 112. (See Fig. 6.) When lowered in place, these clanipscrews 44 'secure the side frames to the brackets 111 112, the feet 42 being secured at the front and rear on op ICO posite sides of the machine to the side frame by means of swinging clamps 46, in the manner shown in Figs. 5 and 2.
