To all whom it may concern.-

Be it known that I, JOSEPH MCCALLUM, of the city of Montreal, Province of Quebe Canadmjhaveinvented certain new and use 'ful Improvements in the Inkirg Mechanism of Printing-Presses; and I do hereby declare that the fiollowing is a full, cleaigand exact" description of the same.

My invention relates particularly to that class of inking mechanism consisting of "an ink-fountain,;a fountain'roll in close proximity thereto, and suitable form-inking rolls consisting of a fornvroll and a distributingroll, the former, the form-roll, adapted to receive the ink from the fountain-roll and distribute it over the types, and the latter, the

- distributing-roll, adapted to grind and distribute the ink evenly over the form-roll.

In cases where it has been required to print in various eolorsas, for in stan co, in printing matter for advertising purposesflvhere itinay be required to print, say, the top line in blue,

the next in red, the next in green, the next in yellow, and the next in black, and perhaps other lines in many shadesit has been necessary heretofore to Set the types of each matter to be printed in a different color or shade to the rec under in independent forms,"

thus necessitat ng a separate impression for each of such colors and shades. The object of my invention is to obviate this difliculty and-enable by a single impression to print as many different colors and shades as can possibly be at any time required and with the use of but a single form.

To that end in y invention may be said,

briefly, to consist,"lirst, in constructing the fountain in separable and preferably independcntlyndynstable sections, and also in forming the fonntaiirroll and, desired, the

d istributing-roll, oi independent rolls orse trons, and, secondly, in aspecial arrangement to divide such independent rolls from one another. i i

For full comprehension, however, of inyinvention reference innst be had to the accompanying drawings, forming a part of this specification, in which Figure 1 is a plan viewof a preferable ernbod nnent of my invention; Fig. 2, an enlarged transverse vertical sectional View thereof,

The fountain is preferably formed of the theshal't oi the fountain-roller,but that portion known as the knii'e-i. 6., the portion forming the bottom or floor of the ink-chain ber instead of being, as heretofore, made in one PiOCG'iS made up of a number of inclependent sections 7, each resting at its rear end. (through di viding'walls to be hereinafter described) upon the base-plate 5an'd at its .forward end upon one or more adjustingable laterally in a slot 8*, extending the full length of. the base-plate, and each screw is slide-in a groove 10 in the npporface of plate 5 and he set at, any desired point along the groove by means or jam-nuts ll.

A number of narrow retaining-plates 12,

in order that the lip of each may overlap the rear edge of' one of the knife-sections, and thus retain it against rearward or vertical displacement. 'Each of these knife-sections ing-wall' 15, which projects forward suinciently to partially encircle a shaft 22, car ried in the bearings G (3. iihese partitions side and near the lower edge thereof a other in order to receive the side of the ward projection 17 on the upper face near the rear end of each of 'such knife-sections serves to facilitate their withdrawal. These partitions are preferably arranged in pairs, "with. their fiat sides in contact and pivotally ends.

These adj usting screws are adj ustsupports, on either side a partition or diVidare flat on one side and provided on other knit'e-seetions tightly between them.

such'independent rolls immediately inalliiie with and in close proximity to each fountainsection and of cqnal'width thereto. These two parts, the fountain and th'efonntain rolh (which are inadcin the form of a sectional fountain and a sectional fountain-rolh) are adapted to feedfive diliere'nteolorsin therfole The shaft 22 is iirsti eiii'ovedfroni its bearin'gs 6 (5-,; and either of the retainingrcollars and 21,- say the one -20, is set at there quired distance from its end oftlie shaft. A spacing-washer ,23, equal in thickness to a pair of dividing-walls 15,- is then placed next tosuch collar, and thcna pair of-pai-titions' or dividing-walls 15 are set in'plaee, the for-w ward ends ofsiich walls, as before mentioned, partly encircling such washer 23. A ioun- 3o tainroll section11il of a width] corresponding to the depth of the top line of types contained :in. the form is thcnjplacerl upon the shaft nextto. and tightly against such washer, and

a' second washer and wall placed nextto'such 35 fountain-roll section. .A knife-sectioncorresponding in width to the fountain-rollsection. is then slid intoithe groovesformed bythe strips 16 on the sides of the walls, and one or more of the retaining-plates 12 set in place.

4o Sufficient spacing-washers 24: are then placed 'on' the shaft next to such latter washer and wall to establish a space equal to that between the top line of types and theone-next -'below it in the fo'rnuand' so on until anindcpendent fo'untaii'i'and fountain-roll section is 'provided for every'line oftypes carried hy the fol-in;

The fountain-roll sections" and spacingwashers-areheld firmly-together by the stee 5o ond retaining-collar 21 and are caused to ro-' tate with the shaft through atfcathcr-and groove connect-ion, theQspaccs hot'wocnil fountains being maintained by inserting" knife-sections between them.

27 may he of ordinary and well-hnown con- .structioii; but I prefer to constructthedis ftributingq'oll in sections. and to cause it to olreciprocate-oiice in every revolution. These "sections are sin'iilar to the feed-roll sections, -except-ing that instead of their being separated by a wall I ma'kethem as much less in width as thedista-nce the distributing-rolls: 651- ciprocates, 's'ay, one-fourth of an .inch, thus providing a one-fourth inch-space between such distributing-roll. sections. and prevents gled, which The compositionforni-rollili, reciprocating d stributing-roll 26, and their carrying-traineing the different-colored inks carried thereby width to their corresponding fountain roll sections. v \Vhen it is desirable to distribute ink over a nn-rower space (say one-eighth of h inch) 2 than thattaken up by the reciprocation of width as the surface of such section. These distributing-roll sections are mounted upon shaft 26 and caused to rotate witli'it by a "feather-and'groove connect on "and ii ay he Tspaced, ifdesired, by spacing-washers,sinumingling, and at the same time through their reciprocation the distributing -rollsect1ons will distribute ink only over a space. equal in lar to those, 24, of the fountain-roll; but I prefer to form a hub 29 on one sideof each' of such rolls, through which they can be soic iredagainst displacement by means of setscrews 30 after having been set at' any desired point along the shaft. The opposite {side of such rollto that having the hub there'- 'on is recessed, as shown in dotted lines in Fig; .1, in order: to enable the surface of one section to be set tightly against the surface fot-thcothcr, which will be necessary when it is desiredto mingle or blend all the dilferent -colors.

The adjustment-of the kniv-est-o regulate the flow of ink from the fountains to the founr 'oll sections is effected by the adj ustingscrews 8, th rough which the knife of each fountain can be independently adjusted. I

flheretwill of coursebe reserve supply of knives, independent fountain -rolls, and independent ,distribntingmolls of all widths' secured to the shaft, or such main roll-sectionmay be removed and exchanged for another roll-section of the required width.

The various arrangements, combinations of parts, and the construction of such parts themselves can be materially changedwithout departingfrom the spirit of my invention.
