UNITED STATESA PATENT OFFICE HOWARD M. BARBER, OF IPAWCATUCK, CONNECTICUT, ASSIGNOR TO C.v B. COTTRLL SONS COMPANY, F WESTERLY, RHODE ISLAND, A CORPORATION OF DELAWARE MULTIGOIOR ROTARY PRINTING PRESS Application led February 7, 1930. Serial No. 426,577.

My invention comprises one or more impression cylinders of a predetermined diameter and one orgmore plate cylinders of a predetermined diameter, the impression cylinder or cylinders being of the same diameter as the plate cylinder or cylinders or a multiple thereof. y

My invention further comprises means whereby the sizes of either the plate or impression cylinders, or both, may be readily and' easily changed without rebuilding the press, by the employment of cylinder shell members of varying'- diameters removably -secured to the cylinder shaft members.

A practical embodiment of my invention is shown in connection with a three color rotary web printingpress sueh as that shown, described and claimed in my copending application, Serial No. 318,506, filed November 10th, 192s.I

3 Fig. 1 represents a detail side elevationil ylustratingrcoacting plate and impression cylinders of the same diameter. y

Fig. 2 represents a similar view illustrating the impression cylinders as twice the diameter of the plate cylinders.

Fig. 3 represents a detail side View of one vof the cylinders (in the present instance a plate cylinder) on an enlarged scale, a por- 0 tion of the longitudinally divided cylinder shell member being broken away to more clearly illustrate the parts inside the same.

Fig. 4 represents an end viewof the cylinder. 1

Fig. lrepresents a longitudinal central Fig. 6 represents a longitudinal section I0 taken in the planes of the lines VI-VI of Fig. 4, looking in the direction of the arrows.

The main frame of the printing press is denoted by 1. The three plate cylinders illustrated are shown as comprising shaft members 2, 3 and i to which in Fig. 1 shell members 5, 6 and 7 respectively of one diameter are removably secured and to which in Fig.

2 shell members 8, 9 and 10 respectivel .Y of another diameter are removably secure f The two impression cylinders illustrated are denotedY as comprising shaft members 1'1 and 12 to which shell members 13 and 14 of a predetermined diameter are removably secured. These impression cylinder shaft members 11 and 12 are shown as mounted in hori- Zontally adjustable bearings 15 and 16. The shell members for the plate and impression rcylinders are shown as longitudinally di vided for facilitating the changing of the shell members of one Adiameter to shell members of another diameter. y

The impression cylinders are shown of the same diameter as the plate cylinders in Fig. 1 and are shown as twice the diameter of the plate cylinders in Fig. 2 but it is to be understood that these are only two examples of the,relative sizes of the plate and impression cylinders as the impression cylinders may not only be the same diameter as the plate cylinders but also any multiple thereof. 'v

In Fig. 1 the upper ,plate cylinder gear 17 is shown as being driven from the upper impression cylinder gear 18 and the lower plate cylinder gears 19 and 20 as being driven from the lower impression cylinder gear :2-1. In Fig. 2 the upper plate cylinder gear 22 is shown as being driven from the upper impression cylinder gear 17 and the lower plate cylinder gears 23, 24 as being driven from the lower impression cylinder gear 21.

The upper and lower impression cylinder gears 17 -and 21 are connected for synchronous action through the registering gear 25, the shaft 26 of which is adjustable horlzontally alongslots 27 in brackets 28,`carried by the main frame 1.

As the means shown herein for securing the shell members to their shaft members is the same for both the plate and impression cylinders, I will describe specifically only one of said means, viz., the means for securing the plate cylinder shell member 5 to its shaft member 2. The shaft member 2 is provided with a sleeve 29 keyed thereto, which sleeve has a flange 30 projecting laterally therefrom. rhis flange has radial slots 31 at i11- tervals around the same. Between the walls of each slot a swinging clamp bolt 32 is pivoted at 33, the inner end of which bolt may be provided with a stop 34 arranged to be brought into engagement with the sleeve 29, to limit the releasing movement of the bolt. A curved shoe 35 is loosely mounted on the bolt between the nuts 36 and an expansion spring 37. j

The longitudinally divided shell member 5 is provided at each end with a flange 38 concentric with the longitudinal axis of the shaft member 2, the inner wall of which flange lits the peripheral face of the sleevev flange 30. This shell member flange 38 has radial slots 39 forming4 extensions of the radial slots 31 in the sleeve flange for receiving the clamp'bolt 32 when it is swung into its locking position with the shoe 35 in engagement with the outer wall of the said flange 38. The tightening of the clamp bolt nuts 36 will serve to lock the divided shell member to the shaft member.

To properly position the sections of the divided shell member on the shaft member I provide the shaft member sleeve with radial dowels 40, arranged to enter holes 41 in the shell member flange 38.

lVhile I have shown four shell clamping and four shell positioning devices for each cylinder, it is obvious'that the number may be varied to suit different requirements.

It will be understood that the divided shell member flange 38 is located the same distance kfrom the axis of the shaft member on all of the shell members of different diameters so that they may be readily interchanged to y form cylinders of various diameters.

The impression cylinder 13 is shown as moved into position to coact with its plate cylinder 5 or 8 by the following means:

A hand Wheel 42 has its cross shaft 43 provided with a bevel gear connection 44, 45 at each side of the machine frame with a screw shaft 46 engaging the bearing 15 which is slidable along a guideway 47. A set screw 48 is arranged in position to engage the bearing 15 and lock it in its adjusted position.

The impression cylinder 14 is shown as.

-gear 58 anc1 in Fig. 2 as a mounting for the change gear 59. The means which I have shown for rocking the supports 56 to bring the selected change gear into driving connection with its impression cylinder gear 21 is shown as a hand wheel 60, the cross shaft -61 of which has a bevel gear connection 62, 63

with a worm shaft 64, the worm 65 meshing with a gear'segment 66 carried by the rocking support 56.

The drive for either the change gear 58 or the change gear 59 is shown as a gear 67 on the shaft 68 which meshes with a gear 69 on the shaft 70. A gear 71 on this shaft 70 meshes with a gear 72 on the stud shaft 57 y The rocking support 56 may be locked in its adjusted position by means of a bolt 73 projecting through an elongated slot 74; ya locking nut 75 being provided for said bolt.

The web 76 is shown as passing 'around suitable rollers 77, 78, 79, to and around the impression cylinder 13. From thence the web is shown as passing around the roller 80 to and around the impression cylinder 14. From thence the web is shown as passing around the rollers 81 and 82 to the delivery point.

The above described means for adjusting the impression cylinders along horizontal planes to bring them into .coaction with their plate cylinders forms part of the subject matter of my copending application Serial No. 318,506, hereinbefore referred to. Also, the changel gear device for driving the printing mechanism forms part of the subj ect matter of the said copending application.

From the above description it will be seen that the sizes of the plate cylinders or the impression cylinders, or both, may be readily changed so long as the impression cylinders are of the same diameter as the plate cylinders or a multiple thereof.

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 limit myself to the particular embodiment herein shown and described, but

What I claim is 1. In a multicolor rotary printing press, plate and impression cylinders, the impression cylinders being the same diameter as the plate cylinders or a multiple thereof, each impression cylinder comprising a shaft member, a longitudinally divided shell member of a predetermined diameter, said shell member being provided with concentric flanges at its ends having holes therein, dowels carried by the shaft member adapted to enter said is holes to position the shell member on. the shaft member, and clamping bolts hinged to the shaft member and provided with shoes adapted to be engaged with said flanges for lslicuring the shell member tothe shaft mem- 2. In afmulticolor rotary printing press,
