THEODORE J. TURLEY, OF NASHVILLE, TENNESSEE.

CHROIVIATIC PRINTING.

- SPECIFICATION forming` part of Letters Patent No. 538,985, dated May '7, 1895.

Application filed October 15, 1894.

To all whom t may concern:

Be it known that I, THEoDoRE J. TURLEY, a citizen ot' the United States, residing at Nashville, county of Davidson, State of Tennessee, have invented Improvements in Chromatic Printing, of which the following is a specification. p

My invention relates to chromatic printing and its object is to provide means whereby matter can be readily printed in two or more colors, on abcd and cylinder press, at. one im` within a chase in the usual manner. I accomplish this object in the manner and byl the means hereinafter described and claimed. In the drawings, Figure l is a plan view of a portion of the bed of'a press with my invention applied, partly broken away. Fig. 2 is a plan view of a moditled form of my invention. Fig. 3 is a sectional elevation on line :n a; of Fig. 2, showing the manner of supporting the Fig. 4 is a diagrammatic view showing the relation of the color-inking apparatus and the black-ink rollers'to the impression-cylinder. Fig. 5 is an end elevation of the right frame supporting the black-ink rollers. Figs. 6, 7, and 8 are details to be hereinafter referred to. Fig. 9 is a plan view of a novel colorfinker used in connection with such a form as shown in Fig. 2. Fig. l0 is an end elevation of one of the frames thereof. Fig. ll is anend elevation of the supplementary frame. Figs. 12 and 13 are details. Fig. i4 is a side elevation of a modification, partly sectional. Fig. 15 isa diagram matic plan view thereof. It is very desirable in color printing, by means of attachments to the ordinary press, to have the devices for such-Work constructed in the simplest Way and capable of being easily and quickly applied to the press in ordinary use, thus enabling the printer to make ready in the shortest time possible; and in color Work, I have used supplemental forms andvholders with gratifying success, but in the present instance I desireto provide means whereby these 'supplemental forms and holders may be entirely dispensed with and by which all the colors may be readily printed at one impression from ordinary type.

Referring to the drawings accompanying Serial No. 525,985. (No model.)

this description, I will state at the outset that while I have shown the -form as extending nearly across the bed of the press, Figs. l and 2, it is to be understood that the matter to be printed may occupy greater or less space, in width or length, the particular width and length, as well as the slightly exaggerated position ot' the bed of the press with respect to the framing, being shown for the purpose, simply, of clearillustration.

In order to eect my purpose I employ in some instances, for the color inking, the ink- .ers disclosed and claimed in my Patent No.

530,865, dated December ll, 1894.

To adapt the color inkers for use in connection with my black ink rollers, a slightly modified construction of the device for causing the color ink roller to ink its appropriate matter is necessary, as will appear in the descri ption to follow.

In Fig. l,the matter is in an ordinary chase, 3, placed laterally of the bed, 2, of the press, to which it is secured in the usuall manner, not deemed necessary to show in the drawings. The press is of course supplied with the ordinary ink fountain and table, located and operating inthe usual way. The form is composed of ordinary type from'which different colors, red, black,'blue, and yellow are t0 be printed, as indicated by the names ot' said colors. The form is locked in the chase by the quoins, 5, as customary.

The color inking devices are/ located in proper position back ofthe impression cylinder, laterally of the press, Fig. l, orlongitudinally, as in Fig. 2, according as the form is placed laterally or longitudinally of the pressA The side frames, 27, of these inking'devices are clamped to the cross bar or bars, 26,sup ported by brackets, 25, upon the framing, l,` of the press. Journaled in these frames are main rollers, 34, distributing and feed rollers, 31 and 36, and mounted above the roller, 34,

is a suitable reservoir, 35, from which ink is 9 IOO placed below type-high, thus depressing the roller, 32, and causing the said roller to ink the form. These strips, 24, are made of standard lengths of metal or other suitable material and can be readily set up with the type with the usual furniture. The roller, 32, is normally held above type-high by any suitable means, as a spring, as set forth in my patent above mentioned.

To give motion to the color ink rollers preferably mount them on a shaft, 28, at one end or both ends of which is placed a friction wheel, 29, running in contact with metal strips, 55, set in the main form at any suitable point, or secured to the bed in any suitable manner. These strips are shown at a slight distance from the edge of the form but they maybe placed along side of the form, or the wheels may be operated by the edge of the chase, if desired.

When the colors extend lengthwise of the form and the latter is placed laterally of the press bed, as in Fig. l, the strips, 24, for operating the color inkers are of uniform height, and the same length as the matter to be printed in a given color; but where the form is placed longitudinally ofthe press bed, these strips must be of different construction, as shown in Fig. 7, where it will be seen that the strip,39,is provided with a cam projection or elevated rail, 41, corresponding in length to the length of matter to be printed in color,- in the instance shown, to the length of the yellow. The roller, 32, being normally above type-high will thus be depressed only when the wheel, 30, is raised by the elevated rail or cam projection, 41, on the strip, 39, as it passes under the rollers. Up to this point the construction and the operation of the inkers somewhat resemble that of my prior patent mentioned, the main point of diterence lying in the omission of the supplemental form and holder, and in the introduction of the metal strips, 24and 39, in the body ol' the form for operating the wheels, 30.

In my former patent means are employed to depress the supplemental form to clear the black ink rollers. My present invention is a material departure from the prior practice in that I provide a novel arrangement of black ink rollers, in order to cause them to ink the part of the form to be printed in black, the preferable construction for this purpose being shown in Fig. 1, and partly in Fig.

'lhe ordinary black ink rollers are removed, and in their bearings are mounted brackets, 6, having projecting bosses or pins, 7, of the same diameter as the shafts of the rollers removed so that they can readily be seated in the bearings of the said rollers. The bosses, 7, may be confined to the bearings by the same cap and screws or bolts used with the old ink rollers.

Supported by the upper ends of the brackets, G, is a transversely extending bar, 13, passing through rectangular or polygonal holes in the frames, in which the said bar can be moved laterally of the press but not otherwlse.

Journaled in suitable frames, 23, clamped to the bar, 13, by set screws, 21', is a shaft, 14, upon which are mounted the black ink rollers, 11, of a standard width corresponding to the width of the matter to be printed in black, said rollers aligning with such matter. On the shaft, 14, are secured collars, 8, to hold the rollers against lateral displacement, and between the separate rollers, 11, in proper order, are placed spacing collars, 9, of less diameter than the rollers. These spacing collars are of various standard lengths such as one, two, three, fou r, tive,six, the., ems, and align with the matter to be printed in colors when properly adjusted. If the blue matter is four ems wide, the spacing collar aligning therewith will be four ems, the. By making these collars of standard lengths the pressman is enabled to quickly and accurately assemble the black ink rollers upon the shaft, which is preferably done as follows: The form is placed upon the imposing stone, at each end of which is secured aplate of the shape shown in Fig. 8; and the shaft 14 is placed in the bearing of these plates, and a collar, 8, is first secured in place thereon at a point opposite the outer line of the first column of matter. The short ink rollers, 11, are then slipped on the shaft, with the spacing collars, 9, in proper order and finally all is clamped in position by 'the other end collar, 8.

The frames or hangers, 23, are unclamped from the bar, 13, and the ink roller shaft quickly set in the bearings of said hangers which are again clamped in position upon the bar, 13,so that the black ink rollers will align with their appropriate matter, and the spaces between them formed by the collars, 9, fall opposite the color type.

Against the sides of the short rollers, 11, I preferably place thin metallic washers, 12, for the purpose of preventing said rollers from spreading while in contact with the form. Any number of the rollers, l1, and collars may be used, as desired.

By this construction of black ink rollers, it will be seen that they can be quickly and accurately adjusted in proper position upon the shaft, and then readily attached to the press. Vith the form placed laterally on the bed, the black ink rollers remain always ata fixed distance above the form; but if, for any reason, it is desired to place the form longitudinally ot the press, as in Fig. 2, the black ink rollers must be raised to clear the type for other colors. To accomplish this, the black ink rollers, 15, are mounted in slotted bearings, 43, of the frames, 23, instead ofcircular bearings, so as to provide for a slight vertical movement of the shafts, 14, on which the said rollers are mounted.

'lwo sets of rollers are preferably employe'd but it is manifest that one set might be used in either of the constructions shown.

Suitable distributing rollers, 2O and 21, set

IIO

` at an angle to the main rollers are mounted loosely on shaftsin bearings on the frames above the rollers, 15, so that the said distributing rollers may vibrate across the face of the ink rollers, 15,as the latter are turned by the ink table, thus spreading the ink evenly on the black ink rollers.

Pivoted to the frames, 23, at 18 are levers, 19, having one end normally held upward by springs, 22, connected to the frames. One arm of each of said levers is preferably provided with a recess in which the end of the shaft, 14, may rest, while the other end carries a wheel, 16, adapted to be engaged by the elevations or cam tracks, 40, on the metal strips locked in the form at each side thereof, and voutside of the strips, 39, hereinbefore described. Y

Depressions, 42, alternatev with the elevations on saidy strips, 38, such depressions corresponding in length to the length of the matter to be printed in colors.

will be alternately depressed and raised, running-in the depressions While the color type is passing under the black ink roller which is thus raised by the spring, 22, above typehigh to clear the color type. Riding on these elevations or rails, 40, the wheel is raised thereby depressing the black ink roller into contact with the black type matter.

With the inkers and strips, 38 and 39, arranged as described, and shown in Fig. 2, it will be plain that the color ink will be deposited upon the appropriate section of the form as the Wheels, 30, are raised by the rails or elevations, 41, as the form passes under the color inkers, while the color ink rollers, 32, will be held clear of the black type as the wheels, 30, pass from the rails,41. In a similar manner, the depressions, 42, on the strip, 38, permit the wheels, 16, to lower thereby raising the black ink roller above the color type, while the elevations, 40, raise the wheels, 16, at the proper time to cause the black ink rollers to ink the matter to be printed in black.

While I find the operation of the color inking mechanism shown in connection with Fig. 2, to` be satisfactory, I prefer to employ the construction illustrated in Figs. 9 to 13, inelusive, in which the metal strips for depressing the color ink rollers are located outside of the form instead of being locked within the said form. Referring now to the said figures, the cross bar, 26; supports the frames, 27', in which are journaled the main ink cylinder or roller, 34, and the vibrating distributing rollers, 3l. The reservoir, 35, is secured to the frames, 27, in a horizontal position, and carries in its feeding end the feed roller,

46, on the end of whose shaft is a ratchet wheel, 47, engaged by a pawl, 48, carried at the upper end of a rod, 50, to which rod a reciprocating motion is given by any suitable means, such as an eccentric, 5l, mounted By this arrangement, it will be seen that as the form movesv under the black ink rollers, the wheels, 16,l

frames, 27.

upon the rotating shaft of main ink roller, or by any other suitable cam rotating with the said ink roller. f

Extending transversely of the frames, 27', is a rock shaft, 52, from which projects two arms, 53, in the outer ends of which is mounted asuitable shaft upon which the feed roller, 54, is journaled. To one of these arms is connected a rod, 55, having a projecting stud upon its lower end engaging a cam, 56, on the end of the main roller, 34, so timed that the said rod maybe raised as the pawl and ratchet are operated to turn the feed roller, 46, thus taking ink from the reservoir and feeding it intermittently to the main roller, 34.

Near the edge of the bed of the press is a supplementary frame, or hanger, 57, which is clamped to the cross bar, 26; and passing through bearingsin this hanger and one of the frames, 27', is a shaft, a, upon the outer `end of which. shaft is mounted a friction wheel-58, in operative contact with a metal bar, 59, preferably corrugated, extending the the ink roller, 34, by a gear, 80, meshing with a gear, 81, on the shaft, d. This bar is provided with an upwardly projecting tongue, 60, uponl which is adapted to be seated, grooved metal strips, 61, corresponding to the metal strips, 40, Fig. 2; and at each end of the said strips, 61, is placed an inclined block, 6l', which is held in position by a friction screw clamp, e, passing through the' side of the block and engaging, by frictional contact, the side of the tongue, 60. These strips are to be of a length corresponding to the length of the matter to be printed in colors. i

A Vibrating shaft, b, passes through a bearing i-n the opposite side of the frame, 57, and through bearings in the lower part of the On the outer end of this shaft is an arm, 62, which is adapted to be raised by an upwardly projecting extension, 79, on a vibrating arm, 63, which is pivotally supported at 49, upon the hanger, 57. The arm, 63, carries at itsfree end a friction wheel or roller, 64, which is adapted to be engaged by the inclined block, 6l', and thus caused to pass without jerk `or jar upon and from the strip, 61, at a predetermined point in the movement of the bed of the press.

An upward extension, 65, upon the arm, 63,` is provided with a laterally projecting lug or boss through which a set screw, 66, passes and bears upon the top edge of the frame, by which the vertical movement of the arm,63, may be regulated.

A stud, 79, on the frame, 57, works in a slot guide, 78, on the arm, 63,011 the guide may be on the frame and the stud upon the hanger, if desired.

Between the frames, 27', on the shaft, b, are laterally extending arms, 67, having studs, 68, projecting therefrom, and engaging the upper edge of an oset in the frames, 69, in which the color ink rollers, 32, are mounted. These frames are slidably connected with the frames, 27, by the vertical guide pins, 70, working in sockets in the lugs, 71, on the said frames, 27', and are pivotally connected to said frames by the pitinen, 72, while they are connected with each other by the tie-rod 73. y

The shaft, c, of the color ink roller, 32, is mounted in curved slotted bearings, 77, in the frames, 69, and a set screw, 74, limits the movement of the shaft, c, in its bearings, which movement may be varied by proper adjustment ot' said set screw. A spring, 75, connects the shaft, c, with the frame, 27', thus normally holding the frames, 69, in the extreme upward position, and consequently keeping the roller, 32, normally out of contact with the form on the bed of the press.

As the wheel, 64, comes in contact with the strip, 6l, it is raised, thereby raising the arm, 63, whose extension, 79, comes in contact with and moves the arm on the end of shaft, b, rocking the latter and causing the arm, 67, to lower. The movement of this arm, 67, downward depresses the frames, 69, and the roller, 32, carried thereby, until the latter is brought into contact with the form on the press, to ink the same. As soon as the wheel is released fom the strip, 6l, the spring, 75, draws ther roller, 32, out of contact with the form.

I have described two arms, 67, for depressing the frames, 69, but it is obvious that one may answer the purpose, though it is preferable to use two because of the equal distribution of the strains secured thereby.

In some cases it may not be convenient or possible to arrange all the color inkers back of the impression cylinder, or under the feed board, as in the construction hereinbefore described; and in back delivery presses itis obvious that these inkers cannot all be applied under the feed board, but must be arranged in front of the impression cylinder. In Figs. 14E and 15, I have shown such a modification of my invention as will readily meet this contingency. In these figures, the inkers back of the impression cylinder are in all respects the same as that disclosed in Figs. 9 to 13. One of these inkers is adapted to print the blue, and a short strip, 61, for depressing the blue roller, 32, will be used, While the other is arranged to print the canary, and a long strip, 61, will be used to depress the canary roller, 32, the strips, 61, in each case correspondingin length to the length of color to be rinted.

The black ink rollers, 1l, are in every respect similar to those employed in connection with the construction shown in Fig. 1. To apply the other colors--in this case, red, orange, and green,-a shaft, 82, is journaled in slotted bearings in the brackets, 87, which brackets also carry the shaft, 14, for the black ink rollers. Upon this shaft, 82, which is capable of a limited vertical movement, are the short ink rollers, 84:, 85, and 86, of standard em lengths, and secured thereon with spacing collars, if desired, in the same manner as the black ink rollers. On the outer ends of this shaft are two friction-wheels, 83, which are of slightly greater diameter than the ink rollers. As long as the Wheels, 83, are on the ink table, the rollers, Si, 85, and 86, will therefore be held above type-high while black ink is being applied to the rollers. 11.

Extending from the edge of the ink table (not shown) to the end of the bed of the press are two strips of metal, 39', in line with the wheels, 83, in each of which strips there is a depression, 42, which is to register With the colors, red, orange, and green, in the form. While the wheels, 83, are in contact with the elevated portions of these strips, the rollers, 84., S5, and 86, are held above type-high, but the moment the wheels, 83, run into the de pressions, 42', the shaft, 82, is lowered and the rollers, 84, S5, and 86 ink the form. To supply ink to these several rollers, I use the frames, 27', with all their appurtenances except the rollers 32, their necessary operating parts, and the supplemental frame and appendages.

Instead of using friction wheels for turning the main ink cylinder, 34, I use a gear, 89, on the shaft, d, meshing with the rack, S3, Which is placed on the edge of the bed of all bed and cylinder presses.

Some of the advantages of my invention are manifest since it is clear that the simple means provided for readily attaching the black ink rollers to the press, and the spacing collars and the rollers of standard lengths are both conducive to economy of time and labor in making ready; and the introduction of the metallic strips, 24, 38, 39, of standard lengths adds further to this result; and again, the provision of separated and independent color rollers, in combination with separate distributing rollers and ink supplies for each of such color rollers, overcomes a serious objection found in prior constructions for printingin a plurality of colors at one impression, since by my construction, I entirely obviate the minglin g or blending of colors, heretofore existing in this type of machines.

IVhile I have shown a particular form of brackets for supporting .the black ink rollers, it is obvious that this form may be varied without departing from myinvention; and it is equally clear that, in cases where it is desired, these brackets may be attached directly to the framing, L.

It is also to be understood that the frames, 23, for supporting the black ink rollers may be duplex, as shown,in either of the constructions used, or single; that is, 'they may have one or more sets of bearings for black ink rollers according as it is desired to use one or more ot' such rollers.

The frame shown in Fig. 5 may be used with the construction shown in Fig. 1, without alteration, and it is intended to be so used, omitting the wheels, 16, because the black ink rollers in that construction are fixed with respect to the form.

Changes may be made in the details of my IOO IIO

invention without departing therefrom, and I desire to state that While I have shown the preferred form which myinvention takes I do not limit myself to the details shown.

I claim as my inventionl. In a printing press, the combination with the impression cylinder and bed of the press, of the main ink rollers upon one side ofthe impression cylinder, the separate color ink rollers upon the opposite side of the impression cylinder normally held above type-high, each of said rollers having a separate ink supply and separate ink distributing, rollers, the form from which a plurality of colors is to be printed, strips of standard lengths secured to the bed of the press by the usual furniture and arranged to positively throw the color inkv rollers into contact with the type in the form at predetermined points in the travel of the bed, and springs for holding the color ink rollers normally above type-high, whereby various colors may be printed from ordinary ltype at one impression, substantially as described.
