Application filed October 31,1905. Serial No. 285,285.

To all whom it may concern:

Be it known that I, GEORGE P. FENNER, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented new and useful Improvements in Inking Arrangements for Printing-Presses, of which the following is a specification.

This invention provides means for regulating the throw of the vibrators or steel inkrollers on a printing-press.

This invention is set forth in the following specification and claims and illustrated in the annexed drawings, in which- Figure 1 is a side elevation of an inking arrangement embodying this invention. Fig. 2 is a plan view of Fig. 1. Fig. 3 is an end view of Fig. 1. Fig. 4 shows parts in a different position than in Fig. 2.

Such parts of the press as the gear a, conveying rotation to the ink-rollers, and the fork l), engaging spool c and operated by nut d to vibrate the ink-rollers, are known and need no special description. The pivots e and f, uniting the nuts (Z to a connection which by pivots g engages links h, vibrating the forks 1), enables the vibration to be regulated.

In the drawings are shown ink-rollers 76, which are rotated or driven as also vibrated to move endwise. A. rack m is suitably reciprocated to actuate the intermediate gear a, which runs between the rack and the gear 0 on the ink-roller 7r. These rolls, as thus noticed, are driven in the usual manner by rack and gears. They are vibrated or moved endwise by screws p and nut d. The screw is part of or fixed to the shaft which supports the intermediate gear a, which runs between the rack and the gear on the ink-roll. The nut d, which reciprocates on this screw, has formerly carried a fork like I), rigidly attached to the nut d, and this fork engages the spool o.

The variable mechanism is an attachment for increasing or decreasing the throw of the fork b in relation to the vibrating nut 61. In the style of press herewith shown there are two vibrators-that is, it is a four-roller press. The drawings show an extension to one of the vibrator-nuts d, said extension havingapivot 6, upon whichis pivoted a casting r, with curved slots in it. Said casting or connection extends from one nut-to the other. The casting at pivot f is slotted to prevent binding or strain when the nut of pivot 0 moves one way and the nut of pivot f moves in the opposite direction and the distance from point e to point f undergoes more or less variation. Such slot in the casting 1" at one of the pivots allows reciprocations of the nuts or their movements in opposite directions while avoiding binding. The nuts have right and left hand threads, respectively, and as the screws 19 are actuated by rack m and gears a the movements of nuts d alternate'. Inasmuch as one nut has a right-hand thread and the other a left, it is obvious that V the casting at the link-attaching points 9 has practically a swinging or oscillatory motion and no other. The forks b are each carried by or attached to a block at. These blocks are placed on suitable seats or depressions in the nuts (1 and can slide or move on the nuts. By having connections or links it for the engagement of the shank of the fork l) and also having this fork b fastened securely in the sliding block i it is easy to see that by swinging or adjusting link 71, one way or the other in the curved slot in the casting or connecting-piece the motion of the fork 7) is increased or decreased in relation to the nut d. Thus it is easy to practically stop the endwise inotion of the ink-roll or to increase it and get more throw than could be had if the fork I) were connected directly to the nut. Two positions of these connections are shown. If the link connections 1" are set near to center of the castings or away from the pivot-points e and f, as seen in Fig. 4, the oscillations of links 71 with forks b and ink-rollers 76 will not be so great as when the connections 1" are set farther apart-as, for example, in Fig. 2.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A device for regulating the vibration of ink-rollers which comprises vibrator-nuts, a connection between the nuts, and links for conveying motion from the connection to the inkrollers.

2. The combination with driving-shafts and nuts reciprocatcd by the shafts, of a connection vibrated by the nuts, links extended from the connection, and ink-rollers having their shafts engaged by the links.

3. The combination between driving-shafts and nuts reciprocated by the shafts, of a con nection vibrated by the nuts, links extended from the connection, and ink-rollers having their shafts engaged by the links, said links being adjustably united to the connection.

4. The combination With driving shafts and nuts reoiprocated thereby, of forks With sliding blocks, ink-roller shafts engaged by the forks, links connected to the forks, and a connection engaging the links and pivoted to the nuts.

5. A vibrating device for ink-rollers comprising driving-shafts With nuts reciprocated thereby, a slotted connection pivoted to the 10 nuts, links adapted to be adjustably pivoted along the slots, and ink-roller shafts engaged and vibrated by the links.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.

GEORGE P. FENNER.
