. 4 Claims.

"This invention "relates to equipmentfor'han -dling inking rollers on anarch or unit type-of :newspaper printin press in the removal-and in- :stallation of rollers'on the press.

'lnking-rollers'on thistype of machine areheavy rubber covered cylinders weighing approximate- Their surfaces must be true and smooth and full efliciency requires removal for grinding or replacement at frequent intervals, whenever the surface is damaged or untrue. So

faras I am aware devicesand equipment now designedto handle such rollers require more or less heavy manual labor by pressmen in lifting the same in and out of the assembly.

It is an object of this invention toeliminate heavy and dangerous lifting and to provide a specialized truck unit to assist inthe quickand efficient transfer of rollers toand from-the'printing pressassembly.

These and other advantages will become apparent from the following disclosure taken in connection with the description of an embodiment of the invention as shownin itspreferred "form by the accompanying drawings," in which:

(Fig. 1 is a diagrammatic end view' of an arch type printing press showing various roller .posi- *tions with the new truck shownpartly' in section and-wheeled into position for removal of one of the rollers;

Fig. 2 is a similar view with the roller transferred from the press onto the truck;

Fig. 3 is a similar view showing the truck equipped to remove another roller from a higher position in the press;

Fig. .4 is a top plan of the truck with a roller supported thereon;

Fig.5 is a side elevationof the truck shownin ,Fig. 4;

Figs. 6 and 7 are fragmentary views showing details of truck. construction; and

Fig. '8 is a fragmentary view showing the mounting of a roller shaft in-the press unit.

In Fig. 1 an arch or unit type newspaper printing press is shown in outline with spaced roller sets I and 2 mounted at each side thereof. "In each set is shown a lower ink drum=3,-two transferinking rollers 4 located between drum'3 and an upper ink drum 5, an intermediate distributor inking-roller 6 associated with drum 5, two upper transfer inking rollers "l, and in contact -.with

inking rollers l a plate cylinder 8 which inturn is'i'n contact with impression cylinder 9. ,ngs will be understood by those skilled in the art, the distributor roller 6 serves to spread and distribute ink evenly on the surface of drum 5. Transfer rollers 4 and 1 between drums 3 andxizand between drum Bandplate cylinder 8 alsozserve to :spread the ink "but further serve. totransfer aneven. film of ink to the plate cylinder =forthe printing operation.

The assembly-of thepress-contains two sets-'of corresponding rollers-"as described. The; housing for the rollers is set-to provide under a: connecting. bridge l0 access-to the inner sidesof each set. This spacing is relativelyznarrow' and; it is through this archway that the inking --.rollers I mounted on theinner sides. areremoved and-.installed.

Shown by Figs. 4 and5ithe newitruckwisipmi vided with a framemember ll formed withsan elongated:narrow bodyportion .12 andv aifiared wider endportion F3. ridjacent the'rfreeiend or front end of portion L 2 theframe issupportedjby wheels l4 mounted on :an axle l5 fixed to "the frame. At the oppositeor rear endrof frame-H caster wheels it are mounted to support'the frame at the outside edges of end-portionl'3.

At each end of the narrow portion t2 brackets H (Figs. 1., 2 and 3) are-mounted thereon as-by bolts or rivets l8. Bracket I1 includes a base member I9 havingasocket 2s, a post-Zl-received in socket 20. and a T-shaped rollervshaftsup- "port 22 mounted on the 'top of post =21 in -the socket :23 of the support.

"in a fixed position when a -roller' isbeing removed or installedaswill be described.

It .willbe notedinthe drawings thattracksare provided across the plates of the press-archway in'the form of channelironguardrails'fil. The runways "3-2 are set for floorlevel-passage-of the front wheels 14 directly onto the rails'into the archway. The truck is guided into position-by the rails 3! which are preferably provided for the full length of -the archway asshown -by-Fig. 4, aa indicating the front and rear boundary lines of the'press-unit.

In this position within the archway the arms 26 are extended to one side of the truck to underlie each end of a roller shaft in the assembly. In the detail view of Fig. 8 the shafts will be noted as carried in a press frame bearing with a removable cap 33. When the cap is removed the shaft is released for passage onto a cradle arm 34 of the socket where it may be manually rolled out of the cradle onto the extension arm 26 and over the slightly inclined top of shelf 22 into notch 24 of the bracket roller support. The arms 26 are then retracted and the roller is wheeled by the truck away from the press and to a cleaning or repair section. A roller is installed in position on the press by reversing these steps described.

It will be noted that during the entire operation of removal from or installation of a roller on a press unit the weight of the roller is entirely supported by the truck unit and is supported at each end of the shaft to prevent damage of any nature to the cylindrical roller surface.

Tilting of the truck is prevented by the guard rails 3| retaining wheels [4 at the front thereof. The rear wheels l6 being set apart at the wide end portion [2 prevent tilting at that end and being of the caster type are used in steering the truck from place to place.

While rails 3| are preferably for the full length of the archway for guiding to roller removing or installing position a short length of channel iron or other means to retain the wheels flat at this location would suflice to prevent tilting.

As described, a post 2| is removable from the bracket assembly of base, post, and roller shaft support and, as will be seen by Fig. 3, a higher post is used for handling the higher rollers 1. A post of an intermediate height may be used for handling of roller 6. Rollers 4 and I on the outer sides of the press may be removed by wheeling the truck at either side.

What I claim is:
