Application filed April 21, 1917. Serial No. 163,742

To all whom it may concern:

Be it known that 1, CHARLES J. GUTBER- LET, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Inkers, of which the following is a specification.

This device belongs to the class that enables the press to produce by a single impression, simultaneously, work in difi'erent colors. It is applicable to fiat work, and particularly to plate printing, where the colors have to meet exactly each other.

The best form of which I am at present aware, in which my device can be built is shown in the drawings and described in the following detailed portion of the specification.

Figure 1 is a side elevation on the line w-zv of Fig. 2. Fig. 2 is a plan view on the line y, y, of Fig. 1. Fig. 3 is an end view of an inking roller and Fig. 4 is a sectional view of the inking rollers.

The ink fountain is divided into a number of ink wells, 5, 5, 5, each of which can contain a diiferent colored ink. Into these wells, 5, 5, 5, dip the rollers, 3, 3, 3. This fountain can be carried in any suitable manner. I have shown it placed on a shaft 1 that rests on supports 8 on the press,a very convenient construction, and one that permits an ink fountain to be picked up and removed and its replacement by another with differently fitted wells without requiring the operator to handle an excessive weight.

The plate inking rollers 24, 25 and 26 are slidable along the ink roller shaft 34 and spread each time they approach the feeding rollers 3, 3, 3, and come together at their ends each time they move into position for delivering the ink. Ordinarily where three colors are used, the middle inking roller will rest on the shaft 34 opposite the middle one of the rollers 3, and the outside inking rollers 24 and 26 will be movable along the shaft 34 so that they can be brought opposite the two outside rollers of the set 3, 3, 3.

The ink roller shaft 34 may be carried by the arms, 7 7, from the vibrator 9.

The shifters for the outside ink rollers 24 and 26 will be moved with the rocking of the shaft 34 and will separate the ink rollers from each other as it brings them into contact with the rollers 3, 3, 3, and will bring them together when they are brought into inking position.

The shifters for the ink rollers, in practice have levers 14, 15, that engage with the rollers 24 and 26 without preventing their rotation on the shaft 34. The engaging devices are conveniently the pins 21 and 22, that fit in annular grooves in the wheels 19 and 20. The lengthwise moving bar 30 connected to the levers 14 and 15 by the links 13 and 16, and moved by the cam slot 17 in the plate 23, is a very satisfactory means for moving the levers 14 and 15. The bars 11 and 12 placed on either side of the bar 30 form guides for it and by pivoting the levers 14 and 15 to the bars 12 and 11 respectively, the links 13 and 16 may make them levers of the first and third class respectively. and give an opposite movement to the rollers 24 and 36 along the shaft 34 with the same movement of the bar 30. The tongues 31, 31, can slide in grooves in the bars 11 and 12. The ink rollers can be dished out, (see Figs. 1, 3 and 4) a ring 35 being left, surrounding the recessed portion 37. They are usually of the well known composition construction with thebox 36 fitting the shaft 34. The edges of the ring 35 will fit closely the corresponding part of the next roller.

If only two colors are used, any one of the rollers 24, 25 or 26 can be dispensed with. If more than three, the levers can be arranged readily to use a larger number, the fulcruming of the levers and the point on them where the motion is given to them being arranged to give them the required separating from and closing on each other. The operation of the device is obvious.

I claim:

1. In a printing press for printing simultaneously in difierent colors, the combination of a vibrating inking-roller shaft, inking-rollers mounted thereon and separable longitudinally along the same, means for vibrating the shaft and rollers mounted thereon between the ink receiving and ink distributing positions of said rollers, and shifters in connection with the inkin -rollers separating the same along said shaft during their travel from their ink distributing to ink receiving positions and approaching them toward each other during their travel from their ink receiving to their ink distributing position.

2. In a printing press for printing simul- Patented Mar. 12, 1218..

taneously in different colors, the combination of a Vibrating inking roller shaft, inking-rollers mounted thereon, separable l'o'ngitudinally along the same, and the ends of the rollers dished out at the central portions of their ends lying adjacent to each; other devices for vibrating, the said shaft, and aro'ller shifter connection with the 1 taneou sly in di-fier'ent colors, series of ink Wells; for the varying, colored inks; feed rollers for each Well, a vibrating inking-roller shaftinking-rollers mounted thereon and movable longitlidinally thereon, means for Vibratingthe said shaft and the rollers mounted thereon from the distributing position of the rollers to a position where they would contact with the feed rollers, and

' a shifter in connection with the inking rollers, separating the same along said shaft, during their travel. from their ink distributing position to their position in contact with the feed rollers and;bringingv themlon gitw dinally together during? their travelfrom the last n'amed positionto" their ink distributing position.

In testimony whereof I affix my signa ture. .7 a CHARLES J. GUTBEQRLET.
