N. Y., a corporation of Virginia Original application January 30, 1934, Serial No.

2 Claims.

This is a division of my prior application filed January 30, 1934, Serial No. 708,933 Patent No. 2,089,331, August 10, 1937.

The principal objects of this invention are to provide means by which a printing press can be run to print three quarters or half the width of the ordinary web without replacing the inking or other roll of the inking system or the employment of an ink regulating blade to prevent the inking of one or more pages in width of web and to provide a fountain roll built in sections, each of substantially one page width, provided with means whereby any number of them may be silenced or prevented from rotating for the purpose of delivering ink when the press is to be run with a narrow width Web.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is a sectional View of a part of a fountain roll illustrating this invention;

Fig. 2 is a cross sectional elevation of an inking trough showing in side elevation, a preferred form of fountain roll made in accordance with this invention, and

Fig. 3 is a plan of the clutch shifting mechanism.

In the printing of newspapers, sometimes it is necessary to use web rolls of different widths to provide the desired number of printed pages in the finish product. Usually full width four page paper rolls, three quarter rolls and half rolls are used, most presses being built to accommodate full width rolls. When a narrow roll is to be used only a portion of the press is operated, of 1 course. Certain types of inking systems are employed in which one of the inking rolls is made of the proper width to furnish ink only to those plates on the press which are being used to print the narrow width web. In using this system, it is necessary to change at least one of the inking rolls in each system when a different width of paper is to be employed, thus wasting a good deal of time.

In the case illustrated the fountain roll is composed of a number of sections, 1 l 1 and I each of cylindrical form and each of one page width. The section F which is next to the end. has secured to its ends by screws 6 two cover plates 9 and It, also cylindrical, and with their peripheries fiush with the outside surface in section l Thus a continuous cylindrical surface is provided. The outer races of two ball bearings II and I2 are also secured-by these Divided and this application July 1937, Serial No. 152,489

cover plates 9 and Ill respectively. The end plate II) also fits closely against a stationary bracket I 3 which, along with a similar bracket 14, serves to support the two ends of a shaft l which is the fountain roll shaft.

This shaft is mounted in ball bearings l6 and I'IY-in the brackets l3 and M respectively. The inner races of bearings [6 are secured in place on the shaft l5 by a threaded nut IS. The inner races of the ball bearings II and I2, and a series of similar ball bearings for the other sections of the fountain roll and the inner race of the ball bearing H, are held in their proper positions by a series of spacers and lock nuts 2| and 22 located at the opposite ends of the shaft l5. At one end a gear 23 is secured to the haft l5 and is adapted to be driven from any convenient part of the press to operate in proportion thereto and drive the fountain roll.

The left hand end of the shaft I5 is provided with a longitudinal hole for the insertion of a sleeve 24 and a rod 25 slidably mounted within the sleeve, the sleeve also being slidable. On the end of the sleeve 24 issecured a spool 26 cooperating with a yoke 21 which, by means of a shaft 28, is pivotally mounted in the bracket 13. This provides means for shifting the sleeve longitudinally. The rod is shifted longitudinally by similar means comprising a spool 3l'and yoke 36.

On the inside end of the sleeve 24 is secured a cross pin 29 which passes through a slot in the rod 25, so as to avoid restriction of the motion of the rod, and extends radially sufficiently to cooperate with radial slots 30 in the end plate 9. All the sections, normally, are driven in a similar way.

It will be obvious that when the sleeve 24 and its pin 29 are in the position shown in Fig. 1 the motion of this sleeve to the right will disengage the pin 29 from the slots 30 and will rotate with the shaft in the space at the right of these slots and will no longer drive the end plate 9 or the section l A chain 3| it attached to the lower end of the yoke 2'! and extends out through a hole in the stationary bracket l3 to a position under the fountain section 1 At this point it is connected with a spring 32, the other end of which is connected with a brake shoe arm 33. When the section is disconnected from the shaft l5 and the spring 32 automatically swings the brake shoe 33 up into contact with the surface of the section l thereby applying friction to prevent the section l from rotating and also the end plate Ill.

In a similar manner, the rod 25 is provided with a cross pin 35 cooperating with a similar clutching device in the end plate on the left end of the section l Disconnection is accomplished through the operation of the yoke 35 and spool 31. A similar chain and brake shoe arrangement is used for placing a frictional drag on the section l when the drive is disconnected.

An opening is provided in the top of the bracket I3 through which a bar may be inserted in the holes provided in the yokes Z1 and 35 to operate either of them. A similar construction is used for silencing the driving sections 1 and 1 those being clutched or unclutched from the right hand end of the shaft [5.

This constitutes a simple means for silencing a particular section or sections of the fountain or other roll and preventing the ink from being brought up through an ink motion which normally feeds into a full width web. It avoids the waste of time required where one or more inking rolls of three quarter or half width have to be substituted for full width rolls and also avoids the necessity of using an auxiliary page width blade for taking the ink from a portion of the fountain roller and preventing the distribution of that ink.

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:

1. The combination with a fountain roll formed in sections substantially in contact end to end, a shaft on which said sections are located and normally free to turn, a longitudinally movable sleeve and a longitudinally movable rod in the sleeve, both concentrically located in said shaft, and means for moving the sleeve and rod independently, of a transverse pin carried by the rod and sleeve respectively, each of two adjacent sections having a slot by which said pins, or either of them, can connect the section to rotate the shaft.

2. In an inking system for a newspaper printing plant, the combination of a fountain roll formed of a series of sections, a shaft on which said sections are arranged end to end substantially in contact and rotatable independently of each other, to transfer ink in an uninterrupted manner from end to end of said roll and for the sections to take ink from the same fountain, and means for securing certain sections to said shaft to rotate therewith to provide for printing on wide or narrow webs as desired, without moving or removing any of said sections.
