English Abstract

HAND-HELD LABELER
Abstract of the Disclosure
There is disclosed a labeler having a frame and
a subframe, with a print head movably mounted on the subframe
for cooperation with a platen. A label hold-down member is
disposed in overlying relation to the platen. The subframe
carries a label roll composed of labels releasably secured by
pressure sensitive adhesive to a web of supporting material,
and the subframe defines a path for the web. The label roll
is mounted on improved mounting structure. A manually
operable actuator drives a gear which in turn effects movement
of the print head. The gear carries a pivotal pawl which
drives a ratchet wheel. The ratchet wheel and a toothed feed
wheel mounted in the subframe are adjustable with respect to
each other. A die roller cooperable with the toothed wheel
is spring-urged against the toothed wheel. The frame in-
cludes a movable frame section mounted on a pivot to facilitate
easy replacement of an ink roller. The pivot also mounts an
applicator roll and a leaf spring of the inking mechanism.
The frame section is releasably latched in place.

Su~anary o f the Invention
Th~ in~rention provide~ an improved mech~ni Sr~ for

the eed wheeL t:o vary the r~gi~tration of the label~3 w.ith
respec:t to th~ del Ami n~ting mea}ls and to the prin~ g means9
This ~ ni sm include~ a pair of c:lutch mem~ers which can be
shifted apart and rotated r~lative to each other to c::hang~
tha ad~u~3tmç~nt between the feed a~d ratchet whPel ~ . The user
can make the adjustment by ~nually driving the feed wheel
wherl the clutc:h members have been shifted A~ l ly out of
clutc:hing engagement with respect to eac:h other. ~lore
p~3ciis:ally, there is a dxive connec:tion betwe~n one clutch
mber and the feed wh~el which prevents relative rotatioll
bet:w~3n that one clu~ch hP~r a~d ~h~ eed wheel but allows
rel tive shifting l,.o~,~,..ent betweg~ that clutch membe:r and the
feed wheel. A spring norr- 11 y holds that clutch m~mher ar~d
the other clutch r~-h~r in clutching engagement with each
