UNITE 2' STATES PATENT FIQ IRVING I. WILD, OF RED BANK, NEW JERSEY, ASSIG-NOR OEONE-HALF TO THEODORE S. CLARK, OF BROOKLYN, NEW YORK.

PRINTING COLOR ATTACHMENT.

To all whom it may concern:

Be it known that I, IRVING L. WILD, a citizen of the United States, residing at Red Bank, in the county of Monmouth and State of New Jersey, have invented a certain new and useful Improvement in Printing Color Attachments, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to color printing attachments for presses and has for its 0-bjcct to provide a construction which may be conveniently and economically applied to presses, especially of the Gordon type and which will enable ink of different colors to be applied to the type.

In carrying out my invention, I employ a plurality of strips, which may be formed as part of a stencil yieldingly supported above the inking disk or platen, said stencil hav ing slits so arranged as to permit the rollers operating thereover to receive ink through the slits, certain of the slits and the corresponding roller being appropriated to one color of ink while certain other slits and the corresponding roller are appropriated to ink of another color.

Generally speaking, the invention may be further denned as consisting of the combinations of elements set forth in the claims hereto annexed and illustrated, in one exempliiication, in the drawings forming a part hereof, wherein Figure 1 represents a perspective view of a Gordon press having my invention applied thereto; Fig. 2 represents a plan view of the inking disk or platen and the frame which supports the stencil; Fig. 3 represents a sectional view taken through the central portion of the disk and frame; Fig. 4, a diagrammatic plan view of the rollers, disk and stencil. Fig. 5 is a plan view of a form, showing the arrangement of the lines of type therein, whereby they may be inked in accordance with my invention, and Fig. 6 is an enlarged detail, partly in elevation and partly in section, of one of the inking rollers.

Describing the parts by reference characters, 1 represents the upper portion of a press Specification of Letters Patent.

of the Gordon type, the same having the ordinary rotatable inking disk or plate 2, roller tracks 3 and piv0tally supported roller arms 4:.

5 denotes a standard having at its upper end a journal 6 for the stud 7 carried by the inking disk or platen 2. This inking disk is provided with the ordinary ratchet 8, by means of which and the pawl 9, step-bystep movement is imparted to the inking disk in a manner well known in the art.

The above mentioned parts are of ordinary construction and need no detailed de scription.

The inking attachment which I provide consists generally of a stencil supported above the disk, the disk having ink applied thereto in concentric circular bands and the stencil having apertures, spaced in accordance with the arrangement of the lines of type in the form, above the portions of the platen or disk which carry the different colored inks, with rollers having projections that register only with the slits in the stencil corresponding to the desired color of ink.

10 denotes a frame having a short sleeve 11 by means of which and screws 12 the frame may be supported by the journal 6. This frame is provided with a recess 13 which receives the inking disk 2. At its upper end, the frame is provided with a plurality of apertured lugs lt through which there extend bolts 15. The lower ends of these bolts are threaded into a cross bar 16. Each bolt has applied thereto, between a lug 14 and its head 16, a spiral spring 18, by means of which the cross bar is yieldingly supported by the bolts.

19 denotes astencil, which may be formed of any suitable material, as heavy stencil paper. This stencil may be secured at its upperend to the cross bar 16 by means of slits 20 adapted to be applied to pins 21 carried by the bar. The lower end of the stencil may be secured, as by means of pins 22, to the lower edge of the frame 10. The parts are so arranged that, as the inking disk revolves, the stencil will be out of contact therewith, as indicated in Fig. 3.

The manner of using the stencil with two colors of ink, say black and red, is as fol- I I lows :'-S uppose the inking disk to be twenty inches in diameter.

red. To the inner central portion of the '7 disk .there'will be applied ink of another 1 color, say black, such ink covering a circu- 1.0

lar area of about ten inches in diameter. A

suitable number of slits 23 will be cut in that portion of the stencil which is above the outer circle of the disk and a suitable number of slits 24., alining with thespaces between the slits 23, will be formed in the stencil above the central portion of the disk.

that'is to say,across that portion of the disk which receives the black ink.

27 denotes a form to be used with the ink ing attachment. In this form, the lines of type 27 extend up and down, or in the same attachment, I employ a special form of cogeneral construction and comprise each a plurality of, roller sections mounted on a mandrel, sald roller sections belng separated by recesses: and the sections being adapted to receive ink through the slits in the stencil.

"Two of these rollers are shown at28 and 29 1 respectively, and the latter roller is shown in detail in Fig. 6. With the arrangement ofcolors selected for illustration herein,the

' roller 29 may be referredto as the red ink roller sections 31, 31 31 and 32.

Theroller 28 is made up inlike manner of projecting portions 33 and reduced portions 34, the

projections and recesses of one roller being arranged complementarily with respect to the projectlons and, recesses on the other roll. If desired, three rollers altogether may be used, as shown, two of which'will necessarily be of identical construction.

distribute on the projections of the rollers 28 and 29 the ink which may be taken from l the exposed portions of the disk.

In operation, the rollers 28 and 29 are moved along the tracks 3 and over the inkmg dlskin the usual manner. The spring support for the stencil enablesthe latter to be pressed downwardly against the diskas the rollers'move over the same, and the pro- With the rollers 28 and29, there maybe, employed small distributing rollers 35, whichserve tov tending from the slits 23, enables. the roller 29, after receiving ink through the slits 23 to be'moved across the disk without bring ing its projections into contact with the central portion of the disk, which portion carries ink ofan-other color from that taken through the slits 23. Furthermore, the strips 25 serve to distribute the ink on the projecting portions of the roller 29. As no strips are provided corresponding to the slits 24', it will probably be desirable to use two inking rollers 28 to insure proper supply of ink to the form. A further distribution ofthe ink on the projecting portions of the rollers is secured by the distributing rollers 35.

:By the construction disclosed, the strips 25 are pressed upon the. surface of the disk only at the time when the disk is not rotated. Furthermore, the inking of the under surfaces of these strips by the disk does not affect the color of the ink which may be distributed on the upper surfaces thereof. It will be understood that the depth of the recesses formed bet-ween the projections of a roller will be greater than the thickness of the stencil or the strips 25, so that there will be no rubbing of the upper surface of the stencil or the strips by the recessed portions 7 of the rollers.

By reference to Fig. 6, it will be seen that the individual projections 31 are built up of one or more independent sections 31, 31 The sections 31 are of the width of a line of type while the sections 31 are a multiple of such width. By this construction, I

am enabled to build up very quickly rolls for use in color printing, which rolls will be provided with surfaces of sufiicient length to receive ink through slits of varying width, the variation in the width of the slits corresponding to the matter to be printed. For instance, the left hand projection of the roller shown in Fig. 6 may comprise a section 3l which is of the width of a single line of type and asection' 31 which is of the width of three lines of type, the whole projection being equal to the width of four lines o of type. The projections 31 may be of the width of a single line of type, while the projection 31 at the right-hand end of the roller is of the same width as that at the left. The roller 28 may be built up in like manner to form projections complementary to those on the roller 29. The

, construction as a whole provides a particularly economincal means whereby a plurality of colors may be applied to the type locked in the form, maintaining the various colors separate from each other and eifeetively distributing the ink on the respective rollers. While for the purposes of illustration two colors of ink are selected, it will be ap parent that more than two colors may be used and that these colors may be arranged differently on the printing disk than described herein.
