CHROMATIC-PRINTING ATTACHMENT.

' SPECIFICATION forming part of Letters Patent No. 538,987, dated May 7, 1895.

Application tiled March 16, 1895.

To all whom it may concern.-

Be it known that I, THEODORE, J. TURLEY, a citizen of the United States, residing at Nashville, in the county of Davidson and,

ed in close register in substantially the time it ordinarily takes for making one impression.

My invention is designed for use particularly where only two contrasting colors are to be printed, although it may be extended to more colors without departing from the essential characteristics thereof.

My object is to provide a convenient attachment for ordinary bed and cylinder presses, whereby the two contrasting colors may be readily and quickly printed in practically the same time it requires to make one impression;.and another essential object is to provide an auxiliary ink table for facilitating this work, which table can be quickly and easily attached and readily adjusted upon the ordinary bed of such press, and also to provide ready and accurate means for adj usting the sectional ink rollers. used in 'connecsectional ink rollers at type-high adapted to receive ink from the ordinary ink table, or other ink distributing apparatus, of the press, with forms arranged side by side transverely or longitudinally of the bed of the press, and it consists further in the details of construe: tion hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of so much of a front-delivery bed and cylinder press as is necessary to show the application of my invention thereto, one side of the framing of the press being removed. Fig. 2 is a plan view thereof, the impression-cylinder being in dotted lines. Figs. 3 to 6 are Serial No. 542,049. (1% model.)

details. Figs. 7, 8, and 9 are side and plan views of a modification. Figs. 10 and 11 are side and plan views of another modification.

Referring now particularly to the drawings, the numeral -1, indicates the impression cylinder which is raised and lowered in the usual way; 2, the feed board. Sectional ink rollers, 4, are mounted in suitable brackets,

a, attached to the frame of the press, which rollers receive their ink from the ink table, 3,

the upper surface of which is type-high. The,

numeral 6, indicates the type line, or said rollers may receive their ink from cylinder distributers when such are attached to the press.

Upon the bed, 5, of the press are locked two forms, 12 and 12', each ofwhich, in the present instance, is one-half the width of the bed, and they are secured within the chase with the usual furniture.

Back of the impression cylinder, 1, is a transversely extending bar, or'rod, 14, supported in brackets, 15, attached to the framing,f, of the press upon which are suspended two supplemental frames, or hangers, 13, forming extensions of the sides of the ink box or reservoir, 27. Mounted in slotted bearings, 16, in brackets, b, on the framing of the press', near the impression cylinder are form rollers, 19, normally pressed downward by springs, 18, bearing upon their shafts so as to keep the lower surface of said rollers slightly below type-high. Where the diameter of the form rollers, 19, is increased, the bearings, '16, need not extend as low as shown since the object is simply to have the form rollers slightly below type-high in order that they may bear with sufficient pressure upon the ink table and the form. Whenever this pressure is found sufficient with said rollers downwardly and outwardly projecting lugs, 10 and 10, through which pass set screws, 8 and 9, respectively, to secure the said table to the bed of the press. The horizontal lugs, 10, are adapted to project over the end of the bed of the press from each side of the table, the outer ends being turned downward so as to pass between the wooden strip, 11 usually at the end of the bed of the press, and the chase. By means of the set screws, the auxiliary table may be adjusted horizontally and vertically, as desired, the upper surface of said table always being held slightly above type-high. The bearings for the form and distributing rollers may be made as shown in Fig. 4, where it will be seen they consist of a bearing block, b, slidable vertically within the slotted bearings, 16, and normally pressed downward by a spring, 18', between the upper end of the slotted bearing and the upper surface of the bearing block, in which block, the shaft of the roller is journaled.

In order to feed ink from the reservoir, or fountain, 27, to the auxiliary table, 7, I mount upon the shaft, 30, of the doctor roller, 28, a lever, 29, having a weight, 31, at its upper end, adjustable or not, as desired, the lower end of which lever projects slightly below the bed of the press outside of the auxiliary ink table. Fulcrumed upon the lever is a pawl, 32, engaging a ratchet wheel, 33, secured to the shaft, 30, of the doctor roller; and also attached to this lever is a tappet block, 34:, the upper surface of which is arranged to come in contact with one end of the shaft of the ductor roller, 35, mounted in slotted bearings, 37, in brackets, 36, forming extensions on or from the side of the ink fountain. A similar lever, 29', without the weight and pawl, extends downwardly from the other side of the ink fountain, and carries a similar tappet, 34, for engaging the other end of the shaft of the ductor roller, the two levers being connected by a suitable tie rod so as to swing together. The ductor roller, 35, is normally out of contact with the doctor roller, 28, but as the bed travels in the direction of the arrow the end of the bed comes in contact with the lower end of the lever, 29, causing the same to swing about the axis of the shaft, 30, as a fulcrum, thereby rotating the doctor roller through the medium of the pawl and ratchet, and at the same time causing the tappets, 3i, to raise the ductor roller, 35, into contact with the doctor roller from which it receives ink from the fountain. When the bed travels back and the lever, 29, is released, the ductor roller drops upon the auxiliary ink table, to which it transfers the ink received from the fountain, the vibrating rollers, 20, spreading the same therein in the usual manner. Instead of suspending the inking apparatus thus described from the framing of the press, it may, if desired, be suspended from separate brackets mounted upon the horizontal framing of the press, in which case, the hangers for carrying the vibrating and distributing rollers may be integral; or they may be separate and supported by separate brackets. In this construction, it will be observed, the distributing rollers never come in contact with the form because they are journaled in bearings outside of the travel of the bed and therefore only touch the auxiliary ink table.

The operation of the device, above described, is upon the same principle as that disclosed in my prior application, Serial No. 531,519, dated December 11, 1894, that is to say, the sheet of paper upon which the matter is to be printed is passed under the impression cylinder in the usual way, two impressions being taken upon the sheet of paper from the forms, 12, 2, on one of which will be ground work, for example, from the form, 12, and the skeleton or close register work upon the other end of the paper from the form, 12. The paper is then turned end for end and passed through the press in the same manner, the ground work being printed in close regis ter with the skeleton work on that end of the paper which contains the skeleton, and the skeleton work being printed on that end which contains the ground work, thus making two completed designs in two contrasting colors at two runs of the press which is equivalent to two contrasting colors substantially at one impressionthat is, if one thousand completed designs are required, five hundred sheets are passed through the press in the manner above described. It will be observed, in this construction, that the distributing rollers are always held above type-high so that they thoroughly distribute tile ink upon the auxiliary table without any danger whatever of smearing the ink upon the type, while the form rollers are preferably slightly below type-high, but as the bed reciprocates they run upon the auxiliary ink table receiving the ink which is thoroughly distributed, and then transfer the same to the appropriate form upon the bed of the press.

It is frequently very difficult to properly and quickly adjust the sectional ink rollersin line with the form which they are to ink since they are usually located either under the feed board or under the delivery tape, 24, close to the impression cylinder, in either of which cases, they are difficult of access, and in order to obviate such difficulty and provide a means whereby they may be readily and quickly adjusted, I provide the construction shown in Figs. 1 and 5, where it is seen that I provide upon one side of the upright framing what I term blind bearings, 21. Upon the shaft of the sectional roller, I cut gage rings or grooves, 22, preferably one near each end, which are to be aligned with the bearers, 23, upon the bed of the press when the shaft of the ink roller is in proper place in its bearings. To adjust the roller, 4, I first place the shaft in the blind bearings, 21, as shown in dotted lines, aligning the gage rings, 22, directly over and in the same vertical plane with the inner edges of the bearers, 23. I then slip the sectional roller, 4, in position over the form, 12',

and when accurately in line therewith, I clamp it securely to its shaft. I then lift it out of the blind bearings and place it in its proper bearings, a, the grooves aligning with the edge of the bed bearers, thus quickly and accurately adjusting the said roller with reference to the form. J

Ipreferably use a groove or ring out upon the shaft of the ink roller, but of course any means attached to the said shaft whereby the shaft and roller may be first adjusted in blind bearings with reference "to each other, and that same adjustment readily secured again when the shaft is dropped into its appropriate bearings will be within the bounds of my invention.

In some cases, it may be desired to print in two contrasting colors where the colors will cover more than half the width of the press, and consequently, it will not be possible toarrange the forms side by side transversely of the bed of the press, as shown in Figs. 1 to 6. In such case, I arrange the forms in line longitudinally of the press, as shown in Figs. 7

to 9, where it will be seen that the two forms 12 and 12' are. so arranged, and in order to ink these forms with the difierent colors without interference or blending, I arrange the form rollers, 4, a sufficient distance out from the impression cylinder to prevent the form, 12;from coming in contact therewith in the extreme movement of the bed to the right; and I arrange the form rollers, 19, on the'opposite side of the impression cylinder, a sufficient distance therefrom to just clear the form, 12, in theextreme movement of the bed to the left, thus providing for the inking of the forms, 12 and 12', by the rollers, 19 and 4, respectively, as the bed moves first in one direction and thenin the other; The auxiliary ink table, 7, and the other attachments are the same in this construction as in the former, the relative arrangement of the forms and their rollers only being changed.

Should the form roller, 4, be placed nearer the impression cylinder, the form roller, 19, must be moved farther out toward the end of the travel of the bed. In both cases. the auxiliary table is detachably secured to the bed of the press, and constitutes an attachment that can be quickly applied to any of the existing presses of the type shown.

Whenever the auxiliaryink table is placed with its surface slightly above type-high, it will be necessary to have the distributing rollers slightly above type-highso that they may not touch the form, if they are located so that any portion of the form passes under them in the travel of the bed, but when the auxiliary ink table is placed below type-high, as in Figs. lO'and 11, and the form and distributing rollers mounted in the same bracket, near enough to the impression cylinder to have the form pass under both sets of rollers, then it will be necessary to provide means for raising said distributing rollers above the surface of the form and holdingthem out of contact therewith. Such means are shown in Figs. 10 and 11, and consist of wheels, 25, loosely mounted upon the shafts of the distributing rollers outside of the frames, 13, and the auxiliary table, 7, and arranged to run upon tracks, 26, formed of strips secured alongside of the form, the wheels being slightly greater in diameter than the distributing rollers. In this case, as the form passes under the distributing rollers, which are also loosely mounted upon their shafts, the wheels coming in contact With the strips, 26, will raise the distributing rollers above the form.

I am awarethat printing presses have been constructed with two ink tables, one at each end of the bed, but such constructions are complete machines and are for the purpose of securing a double rolling capacity for the form and distributing rollers, whereas such is not the purpose of my invention wherein the essential feature is the provision of a detachable auxiliary ink table, to be used as an attachment for ordinary bed and cylinder presses now in use, and this for the purpose of securing the printing of contrasting colors in close register at practically one impres sion. I am thus enabled to print two contrasting colors in close register from forms placed longitudinally of the press, without raising or lowering the rollers, for the paper,

in this instance, is first passed through the press in the usual way, and two colors printed thereon, as before; and it is then turned end forend and passed through the press again,

whereby the two colors are printed thereon in close register, while I effect the same result with the forms arranged transversely of the press, as hereinbefore described.

What I claim as my invention is' V 1. The combination with the bed and impression cylinder of a printing press, of an auxiliary ink table detachably secured to one end of the bed, a supplemental frame located on one side of the impression cylinder, form rollers mounted in bearings on the frame of the press having their lower surfaces at or slightly below type-high, distributing rollers journaled in the supplemental frame, a form on the bed of the press aligning with said rollers, a second set of form rollers on the other side of the impression cylinder receiving, ink from the ordinary ink table, a second form in line with the first form and receiving ink from the latter rollers, substantially as described.
