the shaft 28 is the clutch gear 29 adapted to re
movably engage with the clutch 'gear 38 mounted
on the sleeve 3| which encircles the shaft 28 and
is freely rotatable thereon. The inner end of the
sleeve 3l'carries the bevel pinion 32 that engages
surplus ink from the printing cylinder l8 in
gravure presses.
Since this ink distribution system is the subject
matter of a co-pending application, it is not nec
essary to describe the structural details in this
case. Such mechanism is a peculiar advantage
in web gravure presses such as are shown herein.

threaded to pass through plates 89 set ‘in the press

The tips of the bars 81 are squared for a wrench
so that the pressman may operate same from .

thereby rock the levers 84 on the shafts 85 in

are the runwaybars 99 to afford a track upon
which the cylinder shaft ends 22 and 24 may roll

in removing or installing a cylinder in the press.
By raising the arms 82 the cylinder l8 and its
shaft ends 22 and 24 will be partly lifted from its
inwardly projecting lugs H8 and H9 comprising
a boss on the head 92 by the hollowed-out plate
I2I fastened to this boss by the screws I22
(Fig. 4). The shaft III projects through the
plate I2I as shown. Fastened to the’ outer side
of the head 92 is the removable plate I29 to pre
vent oil from the ball bearings II8 from being
scattered‘ on the press frames II and I2.
Means are provided for exerting pressure on the
cylinders i9 and 20 according to printing require 10
ments, which pressure is adjusting either sepa
rately at either side of the press or simultaneously
at both ends of the cylinders, coupled with devices
for raising these cylinders I9 and 29 out of con-,
tact with the cylinder I8, all of which is best 15

may then be rdlled out of the press frames II and
