MERRITT GALLY, OF NEYV YORK, N. Y.

COLOR-INKENG APPARATUS FOR PRINTlNG- RES8ES.

SPECIFICATION forming part of Letters Patent No. 309,220, dated December 16,188

No model.)

T 0 all whom it may concern:

Be it known that I, MERRI'r'r GALLY, a citizen of the United States, residing in the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Color-Inking Apparatus for PrintingPresses, of which the following is a specification.

In the accompanying drawings, Figure l is an end view of an ink-distributing cylinder, form-inking rollers, distributors, changers, or lateral distributors, doctor-roller, and inkfountain arranged for printing lines of dif- Fig. 2 is a view, partially sectional, of the compound changers. Fig. 3 is a cross-section of changer-sleeve and adjustable distributing'ring. Fig. 4 is a perspective view of a section of the ink-fountain with adjustable partitions, showing the adjustable cutoff slides. Fig. 5 is a crosssection of partition and cut-off slide. Fig. 6 is a modification of the changer with combination sleeve and movable distributing-rings, and Fig. 7 is a plan of sleeves and end view of sleeve and distributing-ring.

The object of my invention is to furnish a very simple and easily-adjusted inking apparatus for printing in several colors with a single impression, and also to enable a printer to make up his ink-fountain and lateral distributers to correspond with the measure of the lines of the form of types to be printed in different colors without disturbing or preparing any part of the press proper, by the mechanism hereinafter described and claimed, thus allowing the press to be used for other work while he is arranging the inking apparatus for the color job. i

In Fig. 1, A A A are the form-inking rollers of the press, and O O are ordinary soft distributers.

B and B are metallic changers or lateral distributers. I construct the metallic changers as shown in Figs. 2, 6, three of which are in Fig. 2 shown, each having a distance of lateral movement differing from the others, and being provided with rings 6, differing in width. The changer which has the shortest lateral movement is provided with narrow rings, and those having a larger lateral movement are provided with wider rings. The width of each ring and its movement measured together is made to correspond to the measure of a certain kind of type, and represents bands of color for such lines. As the rings are not only adjustable but removable, rings of a great variety may be kept on hand to make up a combination adapted to any job. The changers are made up of three principal parts, to wit: a shaft, 1? P, with squared ends to prevent its turning in the slots of the roller-brackets of the press, which shaft has no lateral motion relatively to the form or bed; a sleeve, f, which moves laterally with respect to the form or bed on the shaft, and the rings which are slid to position on the sleeve and made fast thereto with a small set-screw.

Fig. 3 represents a cross section of the sleeve with a ring screwed fast to it, a groove or thread being made in the sleeve to take the point of the screw. The head of the screw is sunk below the face of the ring. The sleeve f is given its lateral movement by means of an ordinary crescent connected with the sleeve and working in an ordinary cross thread screw. For the changer with shortest throw only an inclined groove and pin are necessary.

To properly distribute the ink the wider rings require more movement than the narrow rings, and for this purpose the shafts are made with screws of different lengths, accord ing to the throw required. To lessen the number of shafts required to correspond with a great variety of type-lines, each shaft is provided with a number of screws cut therein, and the crescent may be changed from one to the other when required.

For a press in which only a limited number of changers can be used, and not enough to make up the desirable number of lateral movements, I make up some of the changers, as shown in the modification, Figs. 6 and 7. I divide the sleeve into sections corresponding with different type-measurements, as t t, 850., and either square the shaft so the sleeve will not turn upon it, or provide the shaft and sleeves with groove and spline or pins to prevent their turning. Some of these short sleeves, as t, I use to separate the rings from each other, and others, f, Iprovide with rings 0. For these rings which are wide enough to slide easily on their sleeve, I make an inclined groove around the sleeve and provide the ring with a pin to move in the groove, thus giving lateral motion to the ring. .1 WVhenthe ring is too narrow to slide easily upon the sleeve without cramping, I make the groove in the sleeve sinuous, as shown in f, Fig. 7, making six curves or angles-three to the right and three to the left-around its circumference. I then use three pins, as shown, in ring 6, Fig. 7. The three pins prevent the ring from 1 cramp ing, producing an easy lateral m ovement.

The changer made up in this manner may have a number of rings on a single changer, all having different degrees of lateral movement. It is preferable, however, when agreat number of colors and movements are employed, to use one or more of the changers of Fig. 2 for the very narrow lines, and those of Fig. 6 for the variety of wider lines. The narrowest lines cannot so well be accommodated with the changer made up as in Fig. 6, and asufficient number of movements could not readily be produced by a few of the changers of Fig. 2.

In Fig. 1. the ring of changer B may be covered with soft composition and used directly in contact with the distributing'cylinder E. The metal rings without the covering are, however, preferable, as the soft composition on such narrow rings soon becomes hard and unfit for use. 7

The apartments of the ink fountain are made up to correspond with the rings of the distributors and lines of type or belts of color in the following manner: Movable partitions for the wells of ink-fountains are common,

but they are ordinarily made by casting them from lead between blanks set into the fountain when the cut-off blade'is pressed tightly against the fountain-roller. Such partitions are defective, and the colors from different apartments are liable to mingle when the blade is lowered to increase the feed of the ink. This is caused by aspace being produced either between the bottom of the partition and the blade, or between the curve of the partition and the curve of the roller. I avoid thisdefect by making the partitions as shown in'Figs. l and 4. By the construction shown I can also make the partitions much thinner than in the ordinary manner. The partitions K are made of metal, with their curved end to fit the curve of the fountain-roller and their lower face to rest upon the fountain,

of the roller H. When the blade Sis lowered to increase the flow of ink the wedgeshaped tongue It is thrust forward, as shown, and closes the space left between the bottom of the partitions and the blade, thus preventing any mingling of the colors. The clamp 'Vholds the partition in position, so that there is no leakage between the curve of the partition and the curve of the roller.

The rings and sleeves of the changers may be made of any suitable metal. The rings and such of the short sleeves and washers as are used for making up the divisions between the grooved sleeves may be cheaply cast from type-metal or hard britannia in molds, making them to correspond indimensions with type measurements.

The color apparatus as described is applicable both to platen and cylinder printing-presses, and may be manufactured and furnished independent of the machinery of the press.

What I claim as my invention is- 1. A distributer-shaft secured against endwise movement, a sleeve on said shaft, rings on said sleeve adjustable in the direction of the length of the shaft, and mechanism,'substantially as described, whereby the rings are caused to have a movement in the direction of the-length of the shaft, all combined in an inking apparatus, substantially as described.

2. The combination, with the distributershaft fixed against endwise movement, of a sleeve on said shaft, mechanism, substantially as described, for reciprocating the sleeve,and a series of rings secured to the sleeve and adapted to partake of the movement of the sleeve, substantially as stated.

3-. The combination, with the distributer-v shaft held against endwise movement, as described, of a sleeve arranged to have movemerit on said shaft laterally of the press, and A a series of adjustable rings which vary in width secured to said sleeve, so as to partake of its movement, substantially as stated.

4. The combination, with the distributershaft having squared ends and an inclined thread, of asleeve oil-said shaft, a projection from thesleeve adapted toenter said thread, and adjustable rings on said sleeve, all substantially as and for the purpose stated.

5. The combination, with the distributershaft secured against endwise movement, as described, and having two or more inclined threads of different lengths, of a sleeve on said shaft, and a projection arranged to enter one or the other thread, substantially as stated.

6. The combination, with.the distribute'rshaft fixed against endwise movement, of a sleeve on said shaft, mechanism, substantially as described, for reciprocating the sleeve, and a series of rings varying in width secured to the sleeve, so as to partake of its movement, substantially as described.

7. The fountain -roll H, the partitions K, which divide the fountain having grooves in their under sides, the plates R in said grooves, and the knife S, against which said plates find a bearing, all combined and relatively arranged, substantially as set forth.
