Fig. 11 is a side elevation showing a slightly modified form of press in which the inking mechanisms are carried by a movably mounted frame.

Figs. 12 andl3 are detail views showing in side elevation and in horizontal section, respectively, the detachable connection between the press frame and inking mechanism frame.

The opposite sides of the frame 1 of the printing press shown in Figs. 2 and 3 are provided with front,'rear and intermediate standards 2., 3 and 4:, and supported upon the upper ends of the front standards 2 are the feed-out ylinders 5. The intermediate standards support between them the print ing cylinders which, as herein illustrated, are arranged in pairs one above the other between the standards 4. The standards 4% are provided with horizontally disposed sockets 6 whichare open toward the front end of the press and supporting rails 7 extend from the standards 4 to the frontend oi the frame, the supporting rails being located. adjacent op posits sides of the frame at the level of the bottoms of the sockets 6. l temovably mounted in each of the sockets 6 there is a cylinder supporting block 9, the supporting blocks 9 in horizontally aligned sockets on opposite sides of the press frame supportingbetween them a pair of printing cylinders.

as best shown in Figs. 9 and id each sup porting block consists of top bottom plates 10 which are rigidly connected to end blocks 11 by means of screws 12., Between the end blocks 11 there are mounted two T journais 13. Midway between the ends of nested on the enter side ht" tilt? serves to retain a wedge 5 between the two journals mounted in the block. The wedge has one inclined side face and one of the journal sections has its inner face formed at the same inclination as the wedge. The side plate 14 carriers an adjusting screw 16 which bears against the outer end of the wedge and serves to adjust the wedge between the two shaft journals. One of the end blocks 11 carries an adjusting screw 17 which may be turned to tightly clamp the adjacent journal against the wedge and to press the other journal against the opposite end block 11. By adjusting the wedge and the screw 17 the pressure with which the cylinders are held in engagement may be varied.

Of the two cylinders mounted between the blocks, one cylinder 18 is the plate cylinder which has its shaft 19 extending into one of the journals 13 in each of the two supporting blocks and the other cylinder of the pair is a tympan cylinder 20 which has its shaft 21 extending into the other journal. The

shafts

19 and 21 have fixed thereto at one end intermeshing

gears

22 and 23 so that one of the cylinders is driven from the other to feed the paper between the cylinders. One-of the

cylinder shafts

19 or 21 projects beyond the supporting block and has fixed thereto a bevel gear 24 which is adapted when the supporting blocks are in place in the sockets 6 of the press frame to mesh with bevel gears 25 at the forward end of horizontal shafts 26. A driven shaft 26 is providedfor each of the superposed pairs of printing cylinders and these shafts carry bevel gears 27 at their rear end which are driven through bevel gears ona vertical shaft 28 on the rear standard 3. The shaft 28 may be driven by any suitable means and, in addition to driving the printing cylin ders, drives the feed-out rollers 5 through a horizontal shaft 29 on the base of the frame 1 alnd a vertical shaft 30 on the front standarc. 2.

The printing press herein illustrated is a press designed for fanfold printing and has a series of printing cylinder units arranged one above the other, some of these cylinder units being arranged to print upon one side of the paper and other units being arranged to print on the opposite side of the paper. If desired certain of the cylinder units may have plates on both cylinders so as to print on both sides of the paper, in which case each cylinder will be both a tympan and a plate cylinder the plates being staggered on the two cylinders. The top cylinder unit in the press shown herein being prcvided with two plate cylinders for this purpose.

Each of the printing cylinder units has an inking mechanism 31 connected to be driven bv the plate cylinder gear and adapted to deliver ink to the plate cylinder in a manner well understood in the art. In order to permit the cylinder units-to be readily removed from the press the inking mechanisms may be detachably connected to the cylinder supporting blocks by any suitable means, attaching hooks 32 being shown herein for this purpose. The inking mechanisms of the cylinder units in which the plate cylinder is toward the front of the press are mounted upon the supporting rails 7 and when detached from the cylinder units these inking mechanisms can be pushed forwardly on the rails 7 into the space between the front standards 2 and when so positioned the cylinder units may be moved forwardly out of the sockets 6 onto the rails 7 in position to be lifted and carried away from the press.

The inking mechanisms for the cylinder units having plate cylinders toward the rear end of the press frame are mounted upon the supporting rails 33 which extend from the intermediate standards 4 to the rear standards 3. These inking mechanisms are also detachably connected to the cylinder units so that the cylinder units can be re leased therefrom and removed from the frame. The paper is fed into the press through feed-in-rolls 34.- mounted in the base of the press frame and passes between the cylinders of the superposed units from the bottom to the top of the press and then forwardly to the feed-out rolls 5 from which the paper may be delivered to the folding mechanism.

For conveying the cylinder units from the press and for delivering cylinder units to the press a crane is provided which has a track 35 extending transversely across the top of the press directly over the supporting rails 7 and a hoist 36 which is mounted to travel on the track. The rails 7 at one side of the track are detachably connected to the

standards

2 and 4 by means of the joint 37 shown in Fig. 7 so that they can be removed to permit passage of the traveling hoist in taking away a cylinder unit or bringing a cylinder unit to the press. The crane track 35 extends from the printing press over a series of makeready stands 38 each of which is provided with end standards 39 having flat tops adapt ed to receive the cylinder supporting blocks 9 so that a cylinder unit may be supported upon the top of the stand. Each of the end standards 39 is provided at one end with a vertical abutment post 40 against which one end of the cylinder supporting block engages and each post 40 has hinged to the upper end thereof a hook 41 which is adapted to be swung down upon the top of the cylinder sup porting block resting on the top of the stand and engages the rear end of a block to hold the block in place on the Eachstand is provided with a transverse shaft l2 adjacent the top thereof and this shaft carries a gear 43 which is so positioned that it will mesh withone of the gears on the cylinder shafts, and the shaft 42 hasa crank handle 44 attached to one end by means of which the cylinders may be turned as may be required in detaching the old plates and replacingthem with other plates. The cylinder units are so supported on the make-ready stands that the journal adjusting devices of the supporting blocks are readily accessible so that, after the plates have been attached to the plate cylinder the cylinders may be adjusted to obtain the proper pressure between the plate and tympan cylinders, and the stands may be provided with suitable inking rollers 45 so that impressions may be taken to show whether or not the cylinders aria adjusted properly to obtain the best resu ts.

After one run of the press has been completed, the cylinder units can be detached from the press frame and conveyed by thecrane to the make-ready stands and other cylinder units which have been previously made ready for a new run may be conveyed to the press by the crane and be quickly put into place ready for operation so that the new run can be started on the press with very little delay. While the press is operating the cylinder units which have been previously removed can be made ready for a new run.

In Fig. 11 of the drawing there is shown a press which is identical with the press shown in Figs. 2 and 3 except that the supporting rails 7 are omitted and all of the inking mech: anisms 31 which are located in front of the cylinder units are mounted upon asupporting frame 46 mounted within the frame 1 of the press on rollers 47 which travel on tracks 48 in the base of the frame 1, the frame 46 being movable from a position in which the mechanisms 31 carried thereby are operatively engaged with the cylinder units to a position in which the frame 46 is between the front standards 2 of the press frame and the space between the cylinder supporting standards 4 and front standards 2 is clearfor the operation of the traveling hoist on the track 35 so that the cylinder units-can be readily removed and replaced by other cylinder units properly set up and adjusted for a new job.

For detachably securing the frame 46 to the standards 4", the standard at each side of the frame is provided with .a keyhole slot 49 adapted to receive the flattened end 50 of a shaft 51 whichis rotatably mounted in the ride member of the frame 46. The shaft 51 has fixed thereto an arm 52 which normally hangs by gravity in a vertical position so that the flattened end 50 of the shaft is in a horizontal position and will pass into and out of the slot 49. To lock the frame 46 against movement the shaft 51 may be turned 20 to bring the flattened end 50 thereof to vertical position within the enlarged portion of the slot 49, the arm 52 being secured in horizontal position by means of a locking pin 53 carried by the arm at its outer end and adapted to enter an opening in the frame 46 as shown in Fig. 13.
