Abstract
Abstract Disclosed are three embodiments of a hand-held apparatus for printing and applying pressure sensitive labels. All the embodiments are disclosed as having a housing, a rigid, metal, frame plate mounted by the housing, a platen and a cooperating print head, a delaminator for delaminating printed labels from the web of supporting material on which the labels are carried, an applicator for applying the printed labels, a feed wheel having teeth for engaging and advancing the web, a manually operable actuator drivingly connected to the feed wheel and the print head, a brake, and an ink roll for inking the print head. The apparatus also includes a feed wheel assembly having a feed wheel driven by a pawl and ratchet mechanism. The pawl and ratchet mechanism is adjustably connected to the feed wheel and a rolling contact type one-way clutch prevents loss of tension in the web between the brake and the feed wheel. In one embodiment, the feed wheel and a drive wheel are selectively positionable by a clutch. In this embodiment, the drive wheel comprises a ratchet wheel, and the clutch comprises a toothed clutch member secured to the ratchet wheel and a toothed clutch member is secured to the feed wheel. By shifting the feed wheel and the ratchet wheel axially relative to each other against the action of a spring, the clutch can be declutched and while declutched the ratchet wheel can be rotated relative to the feed wheel. When the ratchet wheel and feed wheel are in the selected relative position, the spring can be allowed to again effect clutching.
