Abstract

1,244,266. Selective printing. SIEMENS A.G. 9 Dec., 1969 [10 Dec., 1968 (2)], No. 59915/69. Heading B6F. The hammer mechanism comprises a transverse lever 13 which is operable by controllable couplings 11, 12 which are brought momentarily into contact with an impulse-wheel drive 7, 8 which rotates in a plane parallel with the rotative plane of a type-wheel 5. The type-wheel is continuously driven by a motor 1 and gearing 2, 3, 4, and the couplings 11, 12 are moved into a space between the teeth of the impulse wheels 7, 8 by electromagnets 9, 10. Two magnets and two impulse wheels are shown although three may be used. This increases the spacing between adjacent teeth since the couplings 11, 12 are operated in turn. The transverse hammer lever 13 may be restored by a spring 14 or a tooth of the impulse wheels. The impact surface may be the free end of the lever itself or a separate pellet 20 which completes its action by momentum. An adjustably positioned weight 16 on the lever 13 by a spring 17 is used to damp bounce.
