DRIVING IIGHANISI FOR ROTARY PRINTING PRESSES Filed Oct. 26. 1939 'A 4 Sheets-Sheet 4 Q l i NvEN'roR Patented octjze, 1940 UNITED STATES PATENT' OFFICE DRIVING MECI-IANSM FOR ROTARY i PRINTING PRESSES Howard M. Barber, Pawcatuck, Conn., assignor to C. B. Cottrell & Sons Company, Westerly, R. I.,

'I'he object of my invention is to provide means whereby ready access may be obtained to the several parts of the press for various purposes, such as replacement, cleaning, working up of the inko ing mechanisms, etc., any one or moreof the results being obtained by either silencing the printing unit, silencing the inking mechanisms as a unit or individually, or silencing the folder or any combination of the above steps.

My invention comprises a common drive for the printing units, the inking mechanisms and the folder, means being provided for operatively connecting the printing units to and disconnecting them from the drive. Means are also provided for l5 moving the inking mechanisms as a unit a short distance away from their printing units without operatively disconnecting the inking mechanisms from the drive and a further distance to operatively disconnect said inking mechanisms from the drive. Means are also provided for individually and selectively operatively disconnecting the inking mechanisms from the drive. Means are also provided for operatively connecting the folder to and disconnecting it from the drive.

My invention comprises, more specifically, a

combination of power driven shafts, manually operated devices and clutches for accomplishing any one or more of the results above enumerated.

My invention also comprises means for locking the inking mechanisms in contact with their printing units or when moved a short distance away therefrom.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figs. 1 and 1a represent in diagram a side elevation of a double five color web perfecting printing press and its folder, said press being adapted for use with quick drying inks and with ink drying units through which ink drying units the web may be passed after both the first side and the second side printings. 'I'he groups of inking mechanisms are shown in full lines in position to coact with the form cylinders of their printing units and in dotted lines moved away from their printing units a suilicient distance to operatively disconnect the l e6 Fig. 4 represents a detail side view'of one of the devices for manually moving the inker stands to bring the inking mechanisms into and out of coaction with their printing unit;

Fig. 5 represents a detail side view showing the narrow faced driving gear of the inking mecha- 5 nism moved out of mesh with the wide ,faced gear on the drive shaft to operatively disconnect the group of inking mechanisms as a unit from the showing the clutch for manually connecting one l) of the inking mechanisms to and disconnecting it from the drive; and

Fig. 8 represents a detail side view-ofl the manually operated clutch for connecting the folder to and disconnecting it from the main drive shaft.

The flrst side web printing unit is denoted by A and the second side printing unit by A. Each of these printing units is herein shown as comprising an impression cylinder I and flve form cylinders 2. These form cylinders 2 may be in- I0 dividually silenced in the usual manner by mounting them in eccentric bearings iny the main frame 3. The impression cylinder gear 4 of each printing vunit drives the ve form cylinder gears 5. A 86 pair f inker stands 6 `are movably supported in the usual manner upon opposite sides of each printing unit, one inker stand in the present instance carrying two inking mechanisms 1 and the opposite inker stand carrying three inking mechanisms 'I for their respective form cylinders 2n Each inker stand may be provided with the usual rack 8 meshing with a pinion 9 which is rotated in either direction by a hand wheel III through the belt II vand sprocket wheels I2, I3. The first side printed, web is shown'as led through aj dryer I4 and the perfected web is I shown as led through a second dryer I5, which dryers may be of any well known or approved type.

A folder I6 is shown for receiving the perfected |50 web from the dryer of the second printing unit. 'I'he means for driving and manually controlling the operation of the printing units, inking mechanisms and folder are as follows: Y

A horizontally disposed main drive shaft I1 u extends longitudinally of the press and it is rotatably mounted in suitable bearings I8 at spaced intervals along the press. This main drive shaft may be rotated at the desired speed from any suitable source of power not shown herein.

The folder I6 is shown as driven from a gear I9 fast on the main drive shaft I1 and means such as a manually operated clutch 20 of the usual type located in the main drive shaft is employed foroperativelyconnecting the folder to and disconnecting it from the said main drive shaft.

Each of the printing units is shown asdriven from the main drive shaft through a. vertically disposed auxiliary shaft 2l having a bevel gear connection 22, 23 at its lower end with` the main drive shaft and a bevel gear connection 24, 25 at its upper end with the shaft 26 of the impression cylinder i.

Means such as a manually operated clutch 2l of wel1 known or approved typein the auxiliary drive shaft 2i is employed for operatively connecting the printing unit to and disconnecting it from the main drive shaft Il. The handle 2B for operating the clutch 2l may be locked in both positions. y

The group of inking mechanism on each inker stand may be driven from the main drive shaft l'l as follows: a wide faced gear 29 on the main drive shaft ilmeshes with a narrow faced gear 3@ on a longitudinally disposed stud shaft 3i when the inking mechanisms are either in coaction with the form cylinders of their printing unit or in their position moved a short distance away therefrom. This stud shaft 3i is mounted in suitable bearings on the inker stand 6 and a vertically disposed auxiliary shaft 32 which is also mounted in suitable bearings on the inker stand is operatively' connected to the stud shaft through the bevel gears 33, 355.

Each of the inking mechanisms is driven from the auxiliary shaft 32 by means of a 4longitudinally disposed branch shaft 35 mounted in suitable bearings on the inker stand 6. Bevel gears 36, 3l operatively connect the outer end of the branch shaft 35 tothe auxiliary shaft 32 and

bevel gears

38, 39 operatively connect the inner end of the branch shaft 35 to the shaft Il! of one of the rolls of the inking mechanism, it being understood that a gear 4i on said roll shaft 4D drives the balance of the inking mechanism rolls in the usual manner.

Means as a manually operated clutch 42 of well known or approved type in the branch shaft 35 is employed to operatively connect the inkingmechanism i to and disconnect it from the auxiliary shaft 32 and thereby from the main drive shaft Il when the wide and narrow faced gears 29 and 3@ are in mesh.

From the above description it will be seen that any one-or more of the following steps may be carried out by very simple and effective mechanisms: each inker stand may be moved'a short distance to bring the inking mechanisms carried thereby, away from their respective form cylinders without operatively disconnecting the inking mechanisms from the main drive shaft and also the inker stand may be moved-a further distance to operatively disconnect the inking mechanisms from the main drive shaft. Each inking mechanism may b'e operatively disconnected from the drive shaft. Each impression cylinder and its coacting form cylinders may be operatively disco-nnected from the main drive shaft. Means areprovided for locking each inker stand either with the inking mechanisms coacting with their respective form cylinders or when moved a short distance away therefrom.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts Without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the particular embodiment herein shown and described, but

What I claim is:
