Abstract (en)
[origin: US4318452A] The impact beam of a mechanical printer is constructed for noise dampening and yet exhibits a high resistance to wear. The beam unit comprises a block of dampening material which is held along a carrier support wall. A strip of metal is arranged along an exterior, generally flat surface of the block so as to be completely separated from adjacent surfaces of the support wall by a region of block material. The metal strip is arranged to receive the impact of type bars and other noise-inducing mechanical force elements of the printer. The noise emanating from such impacts are dampened as they travel through the block material. There is no direct connection between the metal strip and the housing of the mechanical printer in order to prevent direct transmission of noise vibrations from the strip to the housing.
