SPECIFICATION forming part of Letters Patent No. 356,828, dated February 1, 1887.

Application filed July 3, 1886. Serial No. 207,091. (X0 model.)

To (6 whom it may concern.-

Be it known that I, Mnnnl'rr GALLY, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Ink Distributing Apparatus for PrintingPresses, of which the following is a spec fication, reference being had therein to the accompanying drawings.

In the accompanying drawings, Figure 1 is a side view of the ink-distributing apparatus, showing alsoa part of the supporting framework an d the bed of the prcss,partl y sectional, some parts not essential to the description of this invention being omitted. Fig. 2 is an outline side view showing a modified construc' tion of the improved distributing device.

In Fig. 1 three form-inking rollers, l 2 3, are shown in contact with two distributing cylinders, G D. Two slideways, 0 and (Z, are shown in the framework of the press. In these slideways it is customary to place the composition distributing-rollers of the press; and l have usually driven only the cylinder 0 by means of the positively-moving machinery of the press, depending upon the friction or adhesion of the composition distribnting roller having its hearings in slot to drive cylinder D and apply the ink to form-roller 1. This construction and arrangement of cylinders and rollers appears to be somewhat defective, from the fact that it the distributing-roller in slide cl is not made of extra tough composition and thoroughly seasoned it is liable to tear or to become too soft from heat produced by friction. I obviate this diliicnlty by the construction shown in the drawings.

Instead of placing thejournals of distributer a in the slideway cl, and allowing the dis tributer to touch both cylinders G and D simultaneously, I place roller in a vibrating frame, 6, which is pivoted at m, and allow the roller to touch first one cylinder and then the other, alternately. I produce the movement of frame 6 by means of the bar f,pivoted to the frame 6, as at t, and connect this bar f to or operate it in connection with some regularlymoving part of the press.

In Fig. 1 the bar f is shown as yoked onto the hub of the fountain doctor-roller frame, which has a movement regularly for each entire movement of the press. I connect the barf with the doctor-frame z, for two reasons: First, it forms a convenient operative attachnient having a regularly-occurring movement; and, secondly, it produces the movement of frame 6 at a time most advantageous in the process of distribution and application of ink.

It will be seen by examination of the drawings that during the time the ductor-roller is taking ink on the fountain-roller s the distribution of the ink previously applied to cylinder 0 is going on, and thoroughly-distributed ink is applied to the roller a; from cylinder C. As the ductor-roller leaves the fountain to apply the additional undistributed ink to cylinder G the roller a leaves cylinder 0 and is carried by its frame 6 to cylinder D, from which it does not return to cylinder C until duetor d returns to the fountain-roller s. No ink therefore can reach cylinder D until it has first been thoroughly distributed. The distribution of each fresh application of ink to cylinder 0 is made while the inking-rollers 1 2 3 are inking the form on the face of the bed at B, so that no undistributed ink can reach the form-inking rollers.

The construction as described allows me to drive both cylinder 0 and cylinder D by move ment of the machinery of the press. Gearing is shown in partial view for both cylinders in Fig. l.

The movement of barf is shown in Fig. 1 as produced by means of the canrwheel E and fountain ratchet-lever F. It may be more directly produced by carrying her f down to cam-wheel E, having reciprocating motion given to it directly by the cam, as shown in Fig. 2. The bar f may otherwise be connected with lever F by pivoting at o, as shown by the dotted lines. A distributor may occupy the slot 0, and other distributors be applied to either or both of the cylinders O D, if desired. These are omitted from the drawings for the purpose of more clearly showing the parts and operation of the present invention.

The roller-frame 0 may be pivoted directly to the frame-work H, but is shown as pivoted to a slide, g, which is set in position by means of the set-screw Z. The slide 3 is duplicatedone slide for each side of the press. This construction provides for easy application of the device to presses already in use having the slideways d. The adjustability of the slides y also provides for perfectly lining the roller a as to the distributing-cylindcrs G D, and also for making allowance in the movement of roller a for shrinkage of its composition.

The form-inking rollers 1 2 3 are shown in the drawings, 1 on cylinder D,and 2 3 on cylinder O. A greater number of cylinders may be used having one or more form-rollers to each. The gist of the invention requires that there be at least two distributing-cylinders, and to each cylinder a form-inking roller or rollers.

I claim 1. The combination, with a plurality of distributing-cylinders in a printing-press, from all of which the forminking rolls receive their ink supply, of a distributer -roll alternately engaging said cylinders.

2. The combination, in a printing-press, of a plurality of distribntirig-cylinders, with all of which the form-rolls come in contact for their ink supply, a distributing-roll adjustable relatively to the distributing-clyinders, and mechanism, substantially as described, by which said distributing-roll is brought into contact alternately with the distributingcylinders.

3. In a printing-press in which a plurality of form-inking rolls take their ink separately from a plurality of distributingcylinders, and in combination therewith, a distributing-roll, as a, and its carrier connected with a movable part of the press, by which said distributingroll is brought alternately into contact with the distributing-cylinders at each complete movement of the press.

4. The combination, with the form-inking rolls, as l and 2, and the distributing-cylinders O D, which separately supply said inking-rolls, of the roll a, hungin the frame, and aconnection therefrom to the ductor-roll frame by which roll a is brought alternately into contact with the rolls 0 and D, as set forth.

5. The combination, in a printing-press of the character described, of the distributingcylinders G and D, both positively driven from the moving parts of the press, of the distribnter a,'and a connection, substantially as described, to the moving parts of the press, by

which roll a is made to engage alternately with the rolls 0 and. D.

6. The combination, wit-h the frame having positively-driven distributingcylinders O D and slot (1, of the slide 3 adjustable in said slot, the frame c,pivoted thereto, the roller (1, supported in said frame, and mechanism, sub stantially as described, by which frame 6 and its roll are rocked on the pivots of said frame, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
