Abstract

1,120,892. Selective printing. MARCONI CO. Ltd. 23 Aug., 1965 [11 Sept., 1964], No. 37263/64. Addition to 1,120,893. Heading B6F. Type-band machines; hammer impression arrangements. A selective printer comprises a belt 1, along one vertical edge of which are disposed fixedly or slidably mounted type characters moved along a printing line by one of continuously driven, fluted wheels 2, 3 engaging with correspondingly shaped projections on the underside of the belt to provide a driving connection. for the belt. The type characters may be impressed by a magnetically operated hammer travelling along the printing line at reduced speed with respect to be belt. In another embodiment three hammers are slidably mounted on a belt similar to the type character belt and hammers 23 are mounted in casings 19, 20, 21 spaced along the belt by the length of a print line. The hammers comprise a hammer head 23 mounted on a shaft 24 the end of which is actuated by a bar (not shown). The hammers are spring restored. Type surfaces. In an embodiment in Fig. 4 (not shown) the type characters are mounted on blocks 13 attached to slidable, spring biased shafts 14 and the blocks and shafts disposed within casings integral with the belt 1.
