TO 77?? y tion of a portion of a printing-press equipped 50 Be it known that I, Joan H. SoHUssLER, a with my improvements.

The other red 7 on each friction between the distributing-roll and the side is connected with an auxiliary inkinginking-rolls being sufficient to produce this result. In order that the inking-rolls may work free, there is considerable clearness between the shoulders at the inner extremities roll 13,which, however, need not be described 75 l in detail in this application. My improvement in connection with the inking-rolls consists in providing each roll or the truck thereof at of the journals and the frame forming the each end with an annular flange 1st. These boxes or bearings for the journals; hence i flanges engage the tracks 15 of the frame on 80 the tendency to endwise movement by virtue l the inside and hold the rolls 9 against endof the action of the distributing-roll.

The center of this plate is pro- In the drawings, Figure 1 is a side elevavided with a threaded opening in which is inserted a set-bolt 21, which engages the top of the box 17 and holds the distributing-roll 16 down upon the inking-rolls 9 with any desired tension. By loosening the set-bolt the plate 19 may be moved laterally in the direction indicated by the arrow in Fig. 7 against the action of the spring, since the bottom of the recess 19 is curved in one direction and provided with a shoulder or offset in the opposite direction. By removing the plates 19 the distributing-roll may be removed from the apparatus for cleaning purposes or when for any reason it may be necessary or desirable to do so. The bolt 21 is provided with a locknut 22, which holds the said bolt in any desired position of adjustment.

Mounted on one extremity of one of the distributing-roll journals which is extended beyond the box 17 for the purpose, as shown at 16, is a pinion 23, having flanges 23 extending beyond its cogged periphery and forming a circumferential groove, into which projects a cam or spiral gear 24, which meshes with the pinion. This cam-gear is mounted on a spindle 25, carried by the depending arm 18, formed integral with the bracket 18 on one side of the machine. The function of the cam or spiral gear 24 and the pinion 23 is to impart the endwise movement to the roll 16, whereby the ink is evenly distributed on the rolls 9. The spindle of the roll 16 is constructed and mounted to slide endwise to permit the said movement of the roll within the limits required by the action of the cam-gear. By adjusting the bolt the pressure of the distributing-roll on the inking-rolls may be regulated at will, and the flanges 1 1, which engage the tracks 15 on the inside, as aforesaid, prevent this action of the distributing-roll from imparting a corresponding movement to the inking-rolls, since an endwise movement of the last-named rolls is not desirable, for reasons heretofore stated.

Having thus described my invention, what I claim is 1. The combination with the inking-rolls of a platen printing-press, a distributing-roll mounted to engage the two inking-rolls and having an endwise movement. and a track, of trucks or wheels mounted on the inking-rolls and provided with vertically-disposed flanges which engage the track and prevent the endwise movement of the inking-rolls while passing over the type or printing surfaces.

2. In a platen printing-press, the combination with a suitable frame and a track, of inking-rolls provided with trucks or wheels having vertically-disposed flanges adapted to engage the track of the press on the inside and prevent endwise movement.

3. In a platen printing-press, the combination with an endwise-movable distributingroll, of inking-rolls engaged by the distributing-roll, the said inking-rolls having trucks or wheels provided with vertically-disposed flanges engaging the track of the press to prevent endwise movement of the inking-rolls.

4. The combination with the inking-rolls of a printing-press, and a frame in which said rolls are journaled, of an endwise-movable distributing-roll engaging the inking-rolls, brackets mounted on the said frame and having openings or recesses, boxes slidable in said recesses and receiving the journals of the distributing-roll, and plates slidably connected with the brackets to close said recesses.

5. The combination with the inking-rolls of a printing-press, and the frames in which said rolls are journaled, of an endwise-movable distributing-roll engaging the inking-rolls, brackets mounted on the said frames and having openings or recesses, boxes slidable in said recesses and receiving the journals of the distributing-roll, plates slidably connected with the brackets to close said recesses, and adjusting-bolts threaded in the plates and engaging the boxes for the purpose set forth.

6. The combination with the inking-rolls of a printing-press, and the frames in which said rolls are journaled, of an endwise-movable distributing-roll engaging the inking-rolls, brackets mounted on the said frames and having openings or recesses, boxes slidable in said recesses and receiving the journals of the distributing-roll, plates slidably connected with the brackets to close said recesses, adjustingbolts threaded in the plates and engaging the boxes, and suitable means for normally holding the said plates in place for the purpose set forth.

7. The combination with the inking-rolls of a printing-press, and the frames in which said rolls are journaled, of an endwise-movable distributing-roll engaging the inking-rolls, brackets mounted on the said frames and having openings or recesses, boxes slidable in said recesses and receiving the journals of the distributing-roll, plates slidably connected with the brackets to close said recesses, adjustingbolts threaded in the plates and engaging the boxes, and springs mounted on the brackets for holding the said plates in place against accidental displacement.

In testimony whereof I aflix mysignature in presence of two witnesses.
