Abstract

1,010,988. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 19, 1964 [Nov. 8, 1963], No. 42533/64. Heading B6F. Hammer impression arrangements.-A high-speed selective printer having a type wheel 7 is provided with a hammer 8 comprising a hammer formed by a larger portion 1 and a smaller portion 2 linked together by an elastic connection 3. The portion 2 is guided within a tubular extension 11 of the portion 1, which in turn is guided within a tubular extension 4<SP>1</SP> of a stop 4. The hammer is controlled electro-magnetically and an electrical coil (not shown) is provided on in extension 5 of the portion 1 movable within gap 6 of polepieces 9, 10 of a permanent magnet. Upon passing a current through the coil the portion 1 moves towards the stop 4, which arrests the portion 1 whilst the portion 2 travels on for impression against a selected character on type wheel 7, by virtue of elasticity of the connection 3. When the portion 1 moves away from the stop 4 the portion 2 moves closer to the portion 1 due to the contraction of the connection 3 thereby preventing rebound.
