INKING APPARATUS FOR PRINTING=WIACHINES.

SPECIFICATION forming part of Letters Patent No. 396,612, dated January 22, 1889.

Application filed October 1 0, l 8 8 7.

To @ZZ wiz/0m, it may concern:

Be it known that I, VALTER SCOTT, of Plainfield, in the county of Union and State of New Jersey, have invented an Improvement in Inking Apparatus for Printing-"lia chines, ot which the following; is a specification.

This inkingl apparatus is specially intended for use in printing illustrated newspapers or periodicals, in which it is very important to thoroughly work and distribute the ink upon the engraved blocks or plates to obtain perfeet impressions.

In thedrawings, Figu re l, is a vertical section of my improved press. Fig. 2 is an elevation illustrative of the mechanism for revolving and moving,l the respective parts, and Fig. il is a detached view of the arms and connections for moving` the inking-rolls- The type-cylinders R R are of any desired character for receiving types or plates, and where there are pictures or illustrations to be printed they are to be placed upon the cylin` der R. v

The impression-eylinders Q Q are preferably ot' the saine size as the type-cylinders, and they arc usually arranged as shown, the second impression-cylinder being` below the iirst impression-cylinder, so that the web of paper will pass beneath the type-cylinder R, over the impression-cylinder Q, and around between the cylinders Q Q', and between the second type-cylinder, R', and the second impression-cylinder, Q', and from these the web of paper passes between the cutter-cylinders S S', and isconveyed away, as hereinafter stated.

The ink is supplied from the two ink troughs or fountains A A7, which are of ordinary construction, each containing an ink-roller, 2, to which a slow rotary movement is communicated,

BB are ink-distributincylinders adjacent to the ink-troughs, and I make use of two ink-distributingl cylinders, A A, and intermediate composition rolls, F, in connection with the ink-distributing` cylinder B and two inkdistributing` cylinders A2, and an intermediate ink-distributing` cylinder, B2, and the composition rollers F in connection with the cylinder B and ink-trough A' The composition rollers E are adapted to Serial No. 251,872. (No model) apply the ink upon the types of the type-cylinder R. I have shown ve of these composition rollers E, four of which are in contact with the ink-distributing' cylinders' A A, and there is a metal inking-roller, II, that transfers the ink to the iifth one of these compost tion rollers, and I also employ a composition roller, D, vibrated endwise to aid in distributing the ink upon the cylinder B.

The ve composition rollers E', made use of in connection with the type-cylinder R', correspond to the composition rolls E, and I prefer to make use of an additional compos tion roller, F3, between the upper distributingcylinder A2 and the metal ink-roll H.

The cylinder B2 occupies the same relation to the cylinders A2 and composition distributing-rolls F that the cylinder B and rolls F do to the cylinders A; but I employ composition roller F4 to transfer the ink from the distributing-cylinder B to the cylinder B2, and I use three composition vibrating' rollers, D2, in contact with the cylinders B and B2, as represented.

To assist in the inking of the formsV upon the type-cylinder R', I make use of composition rollers E, receiving` ink from the cylinder A4, which in turn is supplied from the inkdistributing cylinder B by the composition rollers F4, cylinder A5, and rollers F5, and there is an intermediate cylinder, H5, between two of the composition rollers Having thus stated the general arrange ments of the hiking-rollers and cylinders, I remark that certain of these cylinders receive an endwise vibratory motion from the rockshaft I and arms 5, each arm being provided with a pin at the end passing in between collars upon the shaft of the roller or cylinder, as usual, and I prefer to vibrate the cylinders A A and roller D and the cylinders A2 A2 A5 and rollers DDDQ from this one rock-shaft I.

The frame is constructed with reference to the, easy removal of the composition rollers, and the bearings for the rollers H H5 and F5 are preferably adjustable to insure the proper surface Contact between the respective rolls.

In printingpresses ductor-rollers have been made use of to transfer the ink from the roller in the ink-trough to the iirst distributing-cyl inder; but such roller is in contact about half the time with the ink-roller and the other half IOO the time with the distributing cylinder. I make use of two ductor-rolls, G G, to each inkfountain roll, and support these upon a rockshaft, G, with arms S that carry the axis of the respective dnctor-rolls, so that when the rock-shaft G is vibrated in either direction one ductor-roll will be receiving ink from the roll 2 and the other ductor-roll will be spreading the ink upon the distributing-cylinder B or B, thereby enabling me to subdivide the ink-supply, and in order to insure thc proper contact of the du ctor-rolls in the two positions I adjust the bearings or journatboxes 9 nearer to or farther from the rock-shaft G.

The ductor-rolls and rock-shaft acting in connection with the inksdistributing cylinder B are the same as those used with the cylinder B, and the two rock-shafts G receive their motions from one cam, G2, which acts through the roller 10 and rod 11. upon the bent lever 12 and the links 13 and 14 to the crank-arms 15 and 16 on the respective rock-shafts G', and it is preferable to employ a spring, 20, that acts to counterpoise the weight of the parts and press the roller 10 toward the cam G2, and the links 13 and 14 should be made in two parts with right and left hand screws and screw-sleeves 23, so as to adjust the parts and insure the proper contact of the ductorrolls with the fountain-rolls and distributingcylinders respectively.

The tympan-sheet 40 is drawn off the roll AM and through the press bythe action of the type-cylinder R and impi-ession-cylinders G G', and it is guided by the rolls 45 46 47, and the winding-up roll is on the arms N of the draft N2; but l remark that no claim is made herein to the means for operati n g said tympan, as the same forms the subject of a separate application for patent, filed April 17, 1.888, Serial No. 270,935. rlhe web of paper as it is passed from the roll in between the type-cylinder R and impressiolrcylinder Q receives the Iirst impression, and the secon d impression between the type-cylinder R and impression-cylinder Q is to be the picture or illustrated impression, as the ink will be distributed upon the type-cylinder R in the most perfect manner. The web of paper passes off upon the belts 28, that are arranged on the lines of the margins, so as not to blur the impression, and the paper after it is cut between the cylinders S S passes along upon the tapes 30 and beneath the tapes 3l, there being rollers 32 and 33, around which the tapes or belts pass, and I apply the nipping-pulleys K L upon the respective shafts 35 and SU, which nipping-pulleys are placed so as to act upon the margins only of the paper, and they are sufficiently distant from the cutti11g-cylinders S S for the back end of t-he sheet to be cut and partially separated from the web before the forward end of the sheet reaches such nipping-lfmlleys K L, and the shaft is supported in spring or yielding bearings, s`o"that the nipping-pulleys L act with a yielding pressure to nip the paper against the pulleys K, and the speed of the belts and nipping-pulleys is greater than the speed of the web when beingl printed, so that the sheets are separated and properly forwarded to the folding-fly or other delivery device.

l claim as my invention- 1. The combination, wit-h the ink-fountain roller and the ink-distributin g cylinder, of two ductor-rolls, a rock-shaft between the ductorrolls, and arms extending out in opposite directions and supporting such ductor-rolls, and mechanism for vibrating the rock-shaft and moving the ductor-rolls simultaneously into contact with the fountain-roll and distributing-cylinder, respectively, substantially as set forth.

2. The combination, with the ink-fountain roll and the ink-distributing cylinder, of two ductor-rolls, a rocksshaft and arms extending out in opposite directions and carrying the ductor-rolls, an d adjustable bearings upon the arms for one of the ductor-rolls, substantially as set forth.

3. The combination, with the ink-fountain roll and ink-distributing cylinder, of two ductor-rolls, a rock-shaft and arms carrying the ductor-rolls, a crank-arm upon the rock-shaft, an adjustable link, a lever, and a cam and connecting-link for giving motion to the parts, substantially as set forth.

4. The combination,with the two ink-fount ains and their rolls and the ink-distributing cylinders, of two ductor-rolls to each ink-fountain roll, a rock-shaft and arms for the ductorrolls, crank-arms on the ends of the respective rock-shafts, adjustable links connected to the said rock-shaft and connected to each other at their ends, and mechanism, substantially as speciiied, for giving motion to the adjustable links and moving the ductor-rolls simultaneously, substantially as set forth.
