To all whom it may concern:

Be it known that I, ALLEN P. HARLAND, a cltlzen .bf the United States, residi' at Dyersburg, in the county of Dyer and tate of Tennessee, have invented a new and useful Color-Printing Attachment for Printing- Presses, of which the following is a speci cation.

:tion without cha This invention has reference to improvements in color-printing attachments for printing presses, and'is designed to provide a means whereby portions of the printed mattermay be produced in any desired color and in .any desired location simultaneously! the other parts of the with the (printing of work, an :this attachment may be applied to a printing press of any approved construce in said press'and without interfering wit its normal operation.

The present invention provides a means whereby as many different colors may be used as maybe desired, and whereby printby tlie number'of such ing, being done in any color may be changed to any other color by a simple system of substitution of ink reservoirs.

The invention also provides means whereby type forms various colors-maybe brought into perfect register with the spaces left in the main imprint for such colored portions, and this may e done without changingthe position of the type forms withv relation to the parts which. carry them;

The inV6I1t1OI1 llkeWise .cQm rises means whereby any particular type ormusedin any location upon; any one of a'number of form carriers wlllfit any other of the. carriers in the same or another position andwill also fit when the ends are reversed to print right and left.

In accordance with the present invention there are provided a nu ber of units capable of .being les, so that either small or large spaces may e printed in colors at the same time. If the units are used separately then the number of colors is limited only by thenumber of units used. If the units are used in multiples, that is to say, when'gtwo or more units are united to form a composite unit and are used either alone or togpther with other com osite or single units, t en, again, the num er of colors'whichjmay be printed is limited only units employed. V

Furthermcre', the invention contemplates this specification, in which,

usedto produce imprints of Fig. 4 is a horizontal section,

- rintin'g unit made up of orm carriers brought together to constitute 90 used either separately or in multipress- Fast to the frame on each side t erecomposite or single.

" one from the other. Mounted 111 the ournal the use of interchangeable ink reservoirs, so that the color of the imprints may be quickly changed at will without disturbing the type forms or their relation to the surface upon which the imprints are made.

The invention likewise includes means for throwing the members desi nod to produce the colored imprints into an relation with' the surface to be printed, and for regulating the degree of pressure with which the imprinting surface is brought to bear upon the surface to be printed, and also for locking these printing members in the desired position.

The present invention is applicable to various types of printing presses and isnot limited in its application to any particular ty e. p

lhe invention both as to its purposes and its practical embodiment will be best under stood b a consideration of'the-following detailed GSCIlPtIOD, taken in connection with the accompan ing drawings forming part of Figure 1 is a perspective view sh owing the invention applied to a press of the cylinder and reciprocating'bed'type; Fig. 2 is a side elevation of one of the color printing units Fig. 3 is a longitudinal section of the same;

Referring to the drawings, there is shown a portion of the frame 1 of a printing press em loying a cylinderZ and a reciprocating 3,5all of faniiliar'construction and onlyillustrated in the drawing insufficient detail to indcatea cylinder and reciprocati bed invention to a of is a pedestal 4 terminating at the upper endin a cylindrical bearing or journal box 5 and having a side branch 6 alsoternunating *in a journal box- 7, the journal boxes 5 and 7' being in the same horizontal plane butspaced boxes 7 of the two pedestals 41s a roc -shaftout of operative a detail view and Fig. 7 is-a diagrammatic representation V 8 proje'cting through and beyond one of the journal boxes, say theone shown in the foreground in Fig. 1, and there this shaft has applied to it a manipulating lever QY-terminatmg in a handle 10 adjacent to which'the lever '9 carries a latchlever 11 connected in the usual manner toa dog 12 arranged to engage the teeth of a segmental rack 13 formed on the upper end of the side extension 6 of the pedestal 4; By means of the lever 9 the shaft 8 may berocked on its longitudinal axis and will be held in any adjusted position by the'engagernent of the dog 12'with'theteeth of the rack 13. 7 Adjacent butinte'rior se ment 15 having a hub 16 extending to one si ethereof and journaled in the adjacent journal bearing. or box 5.

hfesaa'sprcqker e r wheel 19 on through a sprocket chain 20 are a number" be printed in color, and the shaft 17 may carry any number of these cylinders from one up to a number corresponding to the width of the space to be printed in colors. In Fig. 1 there are shown four such cylinders or form carriers 23, but it will be understood that this is only illustrative and a greater or vless number may be employed. Because the hubs of these cylinders are split, they may be sufficientlyloosened with relation to the shaft 17 to permit of being adjusted to any position 'along' said shaft that may be desired, and -may also berotated about the shaft to any desired point to bring type forms fast on the peripheries of the cylinders or drums into perfect register with the spaces left in the main imprints of 'the press for the reception of imprints to be produced by these type forms. The drums or cylinders 23 'are also provided with series of equally spaced perforations 28 which may be suitablytapped for the reception of screws by means of which the stereotype plates are secured to the periphcries. of the cylinders ordrums. By making'these perforations all accurately spaced about the peri heries of the drums, the stereotypeplates, a so provided with perforations accurately spaced, may be usediinterchangeably upon any. of the drums without the necessity of readjusting the parts to bring them. into register, and these plates may be re versed upon the drums to print right and left. Flanking each side ofa drum 23 are side plates 2930 constituting the supports for the nking rollers and ink reservoirs by means of 109 which the im rinting surface upon the respective cylinder or drum 23 is inked. The plates 29 and 30 are each provided with a through perforation for thepassage of the shaft17 and .also with an elongated slot 31, for the passa e of theshaft 8 to allow for the varying (istanees between the shafts 8 and 17. In order that the plates '29 may be readily removed fromthe shafts 8 and 17 a lower section 32 of each side plate is n made separate from the other section and is hinged thereto by a connecting link 33 adjacent to the passage through which the shaft 17 extends, so that by turning the section 32 about thehin e engaged from 0th the shafts'8 and 17. The plates 29 and 30, are joined by a number-of olts which may be shouldered or otherwise formed to space these plates apart sufficientl'y to receive the drums or cylinders 23, 120 and in order that the sections 32 may be. readily held in place to lock the side plates to the shafts 8 and 17 a latch member 'is hinged to that end of each section 32'remote from the hing e 33, and this latch member has upturned wings 36 partially covering the joints between the free ends of the arts 32 "and the main portion of the side p ates 29 and 30 where these parts cometogether.

order to-hold the latch plate 35 remov 33 the side plate may be dis- 115 der 2 and the the eccentric mounting of the shaft 17, after made- Now,'whe n the ress is set in motion the lever 9 is so manipu ated as, to cause the rotation of th segments'l i and 15 and the shaft 17 is the i eby moved toward the cylindrums or cylinders 23 are brought into operative relation to the paper on the cylinder 2's0 as to make imprints thereon in the spaces left by the main forms of the press whereit is desired that the colored imprints should register.

In adjusting the color-printing cylinders or drums 23 'the'printing forms thereon may be brought into approximate register by being secured by screws entering appropriate perforations 28. Then, to bring these imprinting surfaces into exact register the drums 23 may be moved longitudinallyon the shaft 17 'or rotatively thereon, or both, as the case may be, by first loosening the bolts 27, which may be done with a suitable socket wrench,

tl1en, after-the adjustment has been made, tightening these bolts and; so fixing the relationof the drums 23 on the shaft 17. The degree of pressure of the imprinting surfaces of'the-drums 23 upon the paper maybe regulated to a nicety by means of the lever 9 and which the lever 9 is locked in-the adjusted position by means of the dog 12 engaging between two teeth of therack 13. i

' Now, let it be assumed that it is desirable tochan'ge the colors without changing the the inking type forms upon the drums 23: For this purpose the frames carrying the inking mech anismsare unlatched from the shafts 8 and 17-and again placed thereon'at suchoints as 'may be desired, and this without t e necessity ofcleaning the inking devices, although; of course, it will be necessaryto clean the 1grinting forms upon the drums 2 3, thisbeing, 5

small matter requiring but little t me as compared with the cleaning'of rollers and the press' as a whole.

Now, again, let it be supposed that it is de- 1 sirable to print in colorfrom formswider two or more of t ethan one of the drums 23, then on removing the frames carr 'n the inkipg mechanism rums 23 may be brought into contact to form a single composite drum of two, three" or more times, the width of a. single drum.-. This is indicated in Fig. 5 and the ink-carrying frame is inthis instance -made wide enough to accommodate as manyof the-drums 23 aswould beused for-a printing age, while any number of drums less than t e total number necessary to fill the entire inking frame may be used and may be located within the frame in any manner desired. When such composite drum is used then a printing form such as'indicated at 66 and of sufficient width to Of course the main, forms of the printing press are blank at. the points where the colored imprints are to be;

embrace all the drums 23 which are brought into contact, is employed.

In the form shown in Fig. 5 there may be employed a number 10f overlapping scraper platessimilar to those shown in conjunctlon with a single drum 23, so that if desired the amount of. ink fed to the printing form'fifi may be varied as the exigencies of the case may require. It will thus-be. seen that the single drums 23may-be used separately'or united in multi les to rint larger spaces, or single and multiple rums'may be interspersed, or, in fact, any'combination both of width of print and of color, may be used within the capabilities of the 'partic'ular'press and the number of drums 23 adapted thereto. When a sin le inking frame capable of ineluding a num er of drums 231s used the imprints will be made in one color, but-it is possible to make a single inking frame which will include-a number of drums 23"each with individual inking rollers fed from individual 411k reservoirs, so that a number'of colors may be printed simultaneously. In such case, however, when it is desirable to interchange.

. the colors, all the inking rollers as well as the ,type form carrying drums must be cleaned;

The relative number of revolutions of the color cylinder ordrums will vary with different presses, and, consequently, the. driving, mechanism between themain press'andthe shaft 17 must-bevaried accord1nglyi In Fig. 7 there is shown diagrammatically. a suflicient portion of a web press to illustrate" the application of the invention thereto. In this case the drums 23 and the-corresponding impression drum of the web pressimay be of the same size and rotate with the same speed. Reverting to the inking rollers 38, it Will be observed-that they are rovided with end flanges or heads 67 whic ."engage with the periphery of the correspondinggd-rum .23 on each side of the p'rintingplate. These flanges may be made of metaL and being always in contact with the drum'23 will be positively and continuously rotated thereby, v thus relieving the composition bodies of the rollers 38 from the .strain of rotation which would fotherwise be imparted to them and also insuringan even distribution of ink.
