  • Pneumatic impact tool having improved vibration and noise attenuation
    Patent number: 5407018
    Abstract: Vibration and noise are considerably reduced in a pneumatic impact tool employing a reciprocating work member such as a chisel or hammer by providing composite elastomeric attenuation element in the tool construction. A laminar configuration of the attenuation elements is employed having dual outer layers of elastomeric material in combination with a rigid inner layer and with such attenuation elements being located in the tool construction for physical impact by the work member.
