  • Publication number: 20240116162
    Abstract: A powered tool includes a body, a cylinder, an impact piston reciprocating within the cylinder, and a mount to secure an attachment. The attachment includes a shank and a head sleeve fit over the shank and extending beyond its front end. The head sleeve includes a nozzle at its front end having a slot terminating at a muzzle. An internal hold in the head sleeve is in open communication with the slot. The front end of the shank is disposed within the internal hold and reciprocates therein. A rod is carried within the head sleeve for reciprocal movement in response to reciprocation of the shank with respect to the head sleeve. The rod includes a tongue extending from the internal hold into the slot of the nozzle. The tongue terminates inside the slot for reciprocal movement within the slot in response to reciprocal movement of the shank.

  • Publication number: 20210347029
    Abstract: A multi-stroke powered safety hammer including a cylinder having an end, the cylinder mounted to and extending outwardly from a body to the end, and an impact piston disposed within the cylinder for axial reciprocating movement, the impact piston having a striking surface at a front end thereof. The hammer further includes a mount connected releasably over the end of the cylinder and is configured to receive and releasably secure a base of a tool for reciprocating movement, the base including an end having an impact surface. The end of the cylinder is configured to receive the end of the base for reciprocating movement in confronting relation of the impact surface to the striking surface when the base is received and releasably secured by the mount for reciprocating movement.

  • Publication number: 20200230795
    Abstract: A multi-stroke powered safety hammer system includes a hammer having a body, a cylinder within the body, and a piston carried in the cylinder for reciprocal movement therein. The system includes a quick-connect coupling mount on the hammer, the mount having an inner barrel bounding a hollow interior, an outer sleeve for sliding movement over the inner barrel, and an engagement assembly defined by the inner barrel and the outer sleeve for locking an attachment in the interior. The system includes one of many attachments with an engagement portion; when the engagement portion is applied to the quick-connect coupling mount and the hammer is operated, the piston reciprocates to impact the engagement portion. The attachments guide fasteners, remove fasteners, and process materials.
