This invention relates to improvements in nism are driven from gear l0 receiving its power

wherein the two mechanisms can be separated to
a lesser degree to disengage the inking rollers
from the printing rollers without interrupting
the drive for the inking mechanism so that the
15 vibratingx rollers may continue to ink the inking
rollers.

In addition to moving the inking mechanism 20
away from the printing mechanism to provide
access between the two mechanisms thereby dis
connecting the drive entirely as above described,
it is also desired to move the inking mechanism
away to a lesser extent when no printing is tak- 25
ing place, but to‘retain the driving connection
between the two. In this case, the inking rollers
are moved out of contact with the printing rollers‘
l3 and H, but the inking of the inking rollers will
continue. In other words, they vibrating rollers 30
will continue to rub and spread ink on the ink-'
