Abstract

1,237,645. Selective printing. CREED & CO. Ltd. 23 April, 1969 [27 April, 1968], No. 20661/69. Heading B6F. In a selective printer having a continuously rotating type basket 1, Fig. 1, supporting pivotable type levers 2, the type levers are selectable for impression by a hammer 11, Fig. 2, which displaces a selected type lever 2 into an alternative path defined by a guide 8, Fig. 2. The hammer 11 is magnetically actuated and may comprise a plunger (20, Fig. 3) attractable by an electromagnet (17) to strike a hammer head portion (23), or alternatively may comprise a leaf spring (34, Fig. 7) attractable by a magnet (31) to cause a hammer head (35) mounted thereon to strike the type lever (2). The displacement of the selected type lever is sufficient that a projection 2a, Fig. 1, thereof engages a printing cam 9 to urge the type lever towards a platen 10 for impression. The operation of the hammer is controlled by a pulse generator 12 sensing passing type levers 2 and acting on coincidence with an input L to fire the hammer 11, with a delay equal to the time taken for-a type lever to pass from the pulse generator 12 to the hammer 11. The type basket is mounted on a traversing type carriage.
