  • Publication number: 20240261951
    Abstract: A power tool adapted to impart axial impacts to a tool bit includes a housing having a motor housing portion and a handle portion extending transversely from the motor housing portion, an electric motor supported in the motor housing portion and defining a motor axis, a non-rotatable barrel extending from the motor housing portion and defining a barrel axis parallel to the motor axis, a reciprocation drive assembly coupled to the electric motor and configured to convert torque from the electric motor to reciprocating motion of a piston received within the barrel for reciprocation therein along the barrel axis, a striker received within the barrel for reciprocation in response to the reciprocation of the piston, and an anvil at least partially received within the barrel and positioned between the striker and tool bit. The anvil communicates axial impacts to the tool bit in response to reciprocation of the striker.

  • Patent number: 12005557
    Abstract: The present disclosure is directed to a power tool adapted to impart axial impacts to a tool bit. The power tool includes a housing, an electric motor, and a barrel. The power tool also includes a reciprocation drive assembly coupled to the electric motor and configured to convert torque from the electric motor to reciprocating motion of a piston that is received within the barrel for reciprocation therein. The power tool further includes a striker received within the barrel for reciprocation in response to reciprocation of the piston, and an anvil received within the barrel between the striker and the tool bit. The anvil is configured to communicate axial impacts to the tool bit in response to reciprocation of the striker. The anvil defines an opening and an inner bore that communicates with the opening, and the inner bore at least partially receives a shank of the tool bit.
