Application filed. February 6, 19212. SerialNo. 534,471.

To (4% 20 7mm may concern Be it known that we, Tnoiuls Fa. i'roun'rr and Jones): 1. Hana, respectively a citizen of the United States and a subject of the King; of Denmark, residing at Gleuarin and Towson, respectively, in the county of Baltimore and State of h laryland, have invented certain new. and useful Improvements in lnking Attachments for Cylinder Presses. of which the following is a specifn cation.

This invention relates to roller 1: attachments for cylinder printi, and it comprises means whereby the composition and hard rollers may he readily separated or brought together. ll heu the press is idle, it is desirable to keep the composition rollers out of contact with the hard rollers in order that the surfaces of the couiposition rollers may not become flattened or indented along the lines of contact with the hard rollers. In carrying out the invention, as illustrated in the drawing, the compos tion form rollers. ink fountain and fount roller are arranged on a stationary frame to which is hinged a main rocking frame carrying metal vibrating rollers, adapted to engage the form rollers, and also can 'ing a distributing roller. The rollers on this rocking;- frame are connected by gear train, one member of which is adapted to mesh with a driving gear on the stationary frs .ne when the parts are in their working}; positions. This main rocking frame is movable about its axis, to carry the vibrating rollers out of contact with the form rollers. Upon the main rocking frame is hinged a secondary rocking frame which carries composition. rollers, each adapted to engage the distributing roller and one of said vihratin rollers, and this secondary frame is movable with respect to said main rocking; frame to carry said composition rollers out of engagement with the distributing: and vibrating rollers. A doctor roller, which operates in the usual way to transfer the inlz from the fountain roller to the distributing roller, is mounted on the main rockingframe and. moves with. the latter so that when the roclring frames are moved to separate the hard and composition rollers, the ductor roller will bemoved to a position where it will not interfere with or be engaged by the axis of said latter frame, and these racks are engaged by gears upon a shaft which is mounted in the main rocking; frame and operating by a hand wheel. When this shaft is turned, the rocking frames swing about their axes simultaneously. if the shaft is turned in one direction, all of the rollers will be brought into their working positions, and if the shaft is turned in the opposite direction, the hard and composition rollers will be separated. By suitable looking; means associated with the hand operat ing shaft, the rocking frames may be locked in either operative or inoperative positions.

In the accompanying drawing,

Fig. 7 is a detail view showing the lock- :ing device for the shaft by which the roc king frames are moved to engage and disengage the composition rollers from the metal rollers.

Referring to the drawing, a represents the suitable hearings in the bracket i), the bear form cylinder of a printing press, Z2 indi cates a stationary frame which is secured by bolts 1 to arms 2, which project from the hearings in which the form cylinder mounted. The frame 3) comprises two side plates or brackets 3, having the form shown in Fig. at, and these side plates are connected at their upper ends by the ink fountain 4. which they support. Composition form rollers 5, 6. 7, and 8 are mounted in ings 9 for one of the rollers being shown in Fig. 3, and thebearings for the other rollers being omitted for the sake of clear-- ness. Tl'iefranie I also carries at its upper end a fountain roller 10 for feeding the ink from the fountain, and this roller isoperatedqin the usual way by ratchet mechanism iii. upon the shaft 10* of said roller, (Fig. to feed the inlr from the fountain. Theend plates 3 of the frame 7) each have downwardly and rearwardly extending rins 3 to which are pivotally connected. the end plates l2 of a. frame 0. As shown, each plate 12 has a downwardly extending arm 12, the end of which is connected to the downward extension ofthe adjacent plate "3 by a pivot pin or stud 13. The plates 12 have forward extensions 12".- and the plates are connected together by a rod 14, passing throu h said extensions. The frame 0 has suitable hearings in which are mounted the shafts of

metal vibrating rollers

15 and 16 and a distributing roller 17. The vibrating roller 15 is adapted to engage the form rollers 5 and 6, and the vibrating roller 16 is adapted to engage the

form rollers

7 and 8. These several rollers are connected by a gear. train, as shown, consisting of the

gears

18, 19, 20, 21, and 22, the

gears

19 and 21 being idle gears. In the working position of the parts. the gear 22engages a driving gear 23 which is mounted upon the Sta-- tionary frame Z; and meshes with a large gear 24k which rotates with the form cylinder. The rocking frame 0' also carries at its upper end the rock shaft 25, upon which the arms 26 which support the ductor roller 27, aremounted, the hearings for said shaft being indicated at 28. The end plates of the frame 0 are also provided with bearings 29 for a shaft 30, which is rotatable in said bearings by means of a hand wheel 31.. This shaft carries, near its opposite ends, pinions 32 which engage segmental racks .33, secured to the end plates ofthe stationary frame 6, said racks being curved in the arc of a circle concentric with the axis of the studs 13 about which the frame 0 rocks. With this arangement, by turning the hand wheel in the left-handed or counter-clockwise direction, in Fig. 1. the

pinions wilhmove along the racks 33 a (l the frame 0. in which the shaft ismounted, will be rocked about the studs 13 and the metal rollers on said rocking frame will. be moved out of engagement with'the form rollers, as illustrated in Fig.2. 4

A second rocking frame a is pivoted to the frame a and carries composition rollers 34; and 35, the former of whichis adapted to engage the distributing roller 1? and i 'ibrating roller 15, and the latter of which is adapted to engage said distributing rollei and the vibrating roller 16. This frame (Z comprises two end bars or plates 36, one of which is shown in detail in. Fig. these plates having bearings 36 at their forward ends by which they are journaled upon the rod or shaft 14-. The rear ends of plates 36 are provided with segmental racks 3'4",

' concentric with the shaft is, and these racks ly and the intermediate con'iposition rollers 34 and on the latter frame will be moved away from the metal rollers on the frame '0, as shown in Fig. 2. As the frame 0 is rocked rearwardly, the duct-or roller 27, which is carried by said frame, is moved rearwardly tion roller which swings toward tle fountain roller 10. When the hand wheel is turned in the clockwise direction, the pinions 32 roll along the racks 33 and return the frame 0 to its working position and the gears 38 simultaneously lower the frame (I to its working position wherein the various composition rollers are engaged by the metal rollers and the ductor roller is in position to Vibrate between the fountain roller and the distributing roller.

The rocking frames may be locked in their operative or inoperative positions by suitable means. In Fig. 7. the locln'ng means employed is shown in detail. The hand wheel is keyed to the end 30 of the shaft 30, and slidable thereon, and also has a threaded extension 30", on which is fitted a nut 39. By loosening the nut 39. the hand wheel may be moved away from the bearing 40. The hub of the hand wheel. is provided with an extension 41, in which is socured a pin 42, adapted to enter any one of a series of openings 43 (Fig. 5) in an enlargement of the bearing 4E0. By loosening the nut 39, the hand wheel may be moved outwardly to Withdraw the pin from any openingwith which it may have been engaged, and by then turning the wheel the frames will be rocked/to the desired posi tions. The hand wheel may then be pressed. toward the shaft bearing to'engage the pin with another opening inthe bearing. By tightening the nut 39, the Wheel will be out of the'way of the intermediate composiheld in place against the hearing and. the frames will be locked.

By the mechanism described. all of the rollers can he held positively out of engagement. and brought back positively into ex act alincrnent positions. This. as will be evident, is. an improvement over the ordinary method of mounting the rollers whereby the rollers are lifted individually to their d 5 drop by a-vity to their engaging positions.

For conveniently distinguishing the rocking frames in the claims. l h ave termed the frame (7. which. carries the metal rollers a main rocking frame, and the frame (Z a. secondary rocking frame.
