Abstract
There is disclosed printing apparatus having a pivotally mounted print head which cooperates with a platen, a cam shaft to which a cam is secured for actuating the print head and to which another cam is secured for driving an operating lever. The operating lever is coupled to a slide which drives a feed finger and cam means for actuating an inker. The travel of the feed finger is selectively variable by changing the position of the pivot on which the lever is mounted. The cam means is part of a lost-motion connection which couples the slide to the inker. As the operating lever is cammed in one direction to move the feed finger forward, the inker is moved into and out of inking cooperation with the print head assembly. Because of the lost-motion connection adjustment of the pivot does not affect the length of travel of the inker. When the inker is in inking position the inker is supported at both sides of the platen thereby leaving the platen accessible during threading of the apparatus with the web of record members. The print head assembly includes a pair of print heads, each print head having at least one series of rotatably mounted drive wheels and a support. A plurality of printing bands having different printing elements are trained about the support and respective drive wheels. Each support of each print head is adjustable by exerting forces at opposite ends of the support so that all the printing elements at the support are disposed in a common plane parallel to the platen. The print heads are rigidly interconnected by plates. Set screws threadably received by one of the plates are accessible from about the print head and act on adjusting plates which exert forces at opposite ends of the respective supports.
