Abstract

1288537 Selective printing CREED & CO Ltd 29 July 1971 35645/71 Heading B6F In order to raise a continuously rotating type-wheel 1 to the printing position as it is moved across a page by a type-carriage 3, a grooved wheel 4 integral with the type-wheel co-operates with a bail bar 6 mounted on bellcrank levers. A reciprocating member (10, Fig. 2) which forms part of the type-carriage drive performs one reciprocation for each step-wise movement of the carriage. During each reciprocation, member (10) pushes the arm 9 of the bell-crank causing bail-bar 6 to rise. An electromagnetic latching device (12, Fig. 2) maintains the bell-crank in the raised position if desired. In the lowered position of the typewheel 1, the line printed is visible.
