printing press.

The principal objects of the inventionare to i provide effective means for obliterating the socalled ghosting of the form roller due to the fact that every time it rotates in contact with the plates the latter will remove a pattern of ink from it; to provide two courses of ink from the ink drum to the form roller; to provide for vibration of the various rotary members constituting the means for conducting the ink in the two paths, out of time with each other, and to provide these features with very little additional equipment to that ordinarily employed in newspaper printing presses.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. l is an end elevation of the press side frame and inking motion showing a preferred embodiment of this invention;

Fig. 2 is a fragmentary side elevation of the same, and

Figs. 3, 4 and 5 are developed views of one end of the inking mechanism, showing three different combinations which may be obtained by means of this invention.

The invention is shown as applied to a type of inking mechanism in which a frame I `is mounted on a bed plate 2 and provides a mounting for the driving mechanism and the rollers.

The impression cylinder 3 cooperates with the plate cylinder 4 in the usual way. An ink fountain is shown having a fountain roll I2 which revolves therein and the amount of ink carried thereon is controlled by a blade I3 on the fountain back I4 in the usual manner.

The` usual pick-up roller II is provided to transfer ink from the fountain roll I2 through a soft transfer roller A, which in turn contacts with the ink drum C. Soi't rollers I0 and B on the same side of the ink drum serve to smooth out the ink thereon. Soft rollers 8 and 9 contact with opposite sides of the ink drum and transfer the ink to hard surfaced rollers D and E respectively. These hard surfaced rollers in turn transfer ink to the form rollers 5 and 6.

It will be noticed also that the ink drum C transfers ink directly to these form rollers 5 and 6 so that on.4 'each side there are two paths of ink from the ink drum to the form roller. The form rollers, as usual, transfer the ink to the plate cylinder Il which cooperates with-the imsecured thereto Il are secured. sprockets I0, I9 and 20.

l(ci. 10i-35o) pression cylinder 3 in the usual manner. -In this way the pattern of ink removed from each form roller is filled back in thereon by the two lms of ink that are transferred to it, as above described.

The shaft of the ink drum C carries a worm I5 The ink drum C is rotated in a conventional manner by gearing, not shown. The worm I5 .meshes with a Worm wheel 'It mounted on a transverseshaft Il. On the shaft One end of the shaft Il carries a crank 2| for cooperating with a vibrating spool on the shaft of the roller B. The sprocket I0, through a chain 22, rotates a sprocket 23 on a crank shaft 2t which is arranged to provide longitudinal vibration for the ink drum C. Ilifhe sprocket I0, through a chain 25, drives a sprocket 2t fixed on a shaft carrying a crank for vibrating the roller A. drives a sprocket 2B ilxed to a shaft 29, one end of which carries a crank lill for longitudinally vibrating the roller E through the usual spool. By a coupling 3| the shaft 29 can be coupled to a shaft 32 in alignment therewith.` One end-of the shaft 32 carries a crank 33 for providing The'sprocket 20, through a chain 2l,

longitudinal 'vibration of the roller D. By the use of thecoupling 3| and its adjustment, the angular relation between the shafts 29 and 32 may be varied so that the relative motions of vibration of the rollers D and E canbe changed, as desired` From the construction shown herein it is apparent that the form roller 5 is fed with ink from the ink drum C directly and also indirectly from the ink drum through the soft roller 0 and roller D. Also it is evident that these two members C and D can be vibrated out of time with each other and thereby serve to effectively wipe out the pattern on the form roller 5. Oi course, the form roller 6 is served in a similar way by the ink drum C and roller E. It is obvious also that the rollers D and E may be vibrated out of time with each other and Ialso out of time with the ink drum C.

In Figs. 3, 4 and 5 are shown yseveral ways in vwhich the above mentioned adjustment of vibration can be carried out. Fig. 3 shows the inkdrum C vibrating substantialy 10 from the rollers A and B and the rollers D and E operating on the quarter or apart. Fig. 4 shows the ink drum C and the rollers D and E in the same relationshipas in Fig. 3 but with the rollersAand B 180 from the rollers D and E. Fig. 5 shows the ink drum C and rollers A and B in the same relation as in Fig.

4 but with the rollers D and E vibrating in time with the rollers A and B.

It will be evident that there are numerous combinations that can be obtained so that the machine can be adapted for any particular type of work and the adjustments may be made so that the vibration combination can be best suited to the particular work being run on the press.

The additions to the ordinary ink motion are few and simple and yet the above mentioned ohjects of the invention are accomplished with great eiilciency.

Both the provision of the two paths for the ink and the provision of the widely adjustable vibrations for the several rollers tend to accomplish the same object and they are combined to provide for accomplishing it more eihciently.

Having thus described my invention and the advantages thereof, -I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:-`
