Abstract
A power-driven hammer including a body including a tubular housing and a barrel assembly received in the housing. The barrel assembly has an at-rest position relative to the housing. The barrel assembly includes a barrel having a forward end adapted to hold a tool, an opening, and a rearward end. The barrel assembly includes a mass received in the opening of the barrel. The mass moves in the barrel opening when the hammer is operating through a power stroke and a return stroke. The barrel assembly moves forward and rearward from its at-rest position relative to the housing when the hammer is operating. The hammer includes a vibration reducing mechanism connecting the barrel assembly to the body reducing shock transmitted to the housing as the mass moves forward and rearward in the barrel.
