  • Publication number: 20230017720
    Abstract: A rotary power tool comprises a drive mechanism including an electric motor and a transmission, a housing enclosing at least a portion of the drive mechanism, a spindle rotatable in response to receiving torque from the drive mechanism, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, a sleeve bushing supported by the housing, and a bearing rotatably supporting the spindle. The spindle has an outer race. And, the outer race of the bearing moves along the sleeve bushing during reciprocation of the spindle when the first ratchet and second ratchet are engaged.

  • Publication number: 20220294301
    Abstract: An electric motor built for exposure to high pressure fluid includes a unitary metal sleeve that provides a fluid barrier between the rotor and the stator. An overmolded resin encapsulates the stator windings and reinforces the sleeve to minimize deformation of the sleeve under high fluid pressures. The overmolded resin also fixes the positions of insulation displacement connectors connected to the stator windings, thereby avoiding mechanical brackets and fasteners for holding the insulation displacement connectors in position.

  • Patent number: 11440173
    Abstract: A rotary power tool comprises a drive mechanism including an electric motor and a transmission, a housing enclosing at least a portion of the drive mechanism, a spindle rotatable in response to receiving torque from the drive mechanism, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, a sleeve bushing on an interior of the housing, and a bearing arranged between the spindle and the sleeve bushing and rotatably supporting the spindle. The bearing has an outer race. The spindle is movable relative to the housing in response to contact with a workpiece, causing the first and second ratchets to engage and the spindle to reciprocate while rotating. The outer race of the bearing moves along the sleeve bushing during reciprocation of the spindle when the first ratchet and second ratchet are engaged.

  • Publication number: 20040127908
    Abstract: A clamp assembly according to the invention can be fixed through an opening between adjacent members. The clamp assembly includes a base, a cap opposing the base, and a post connecting the cap and the base in a fastening position on the adjacent members. The post includes a torque-limiting feature to prevent over tightening of the cap and base. The clamp assembly may further include an applier interacting with the post to position the cap and base in the fastening position. A method according to the invention includes placing the base and cap on opposing internal and external surfaces of the adjacent members. The post is rotated to bring the base and cap to the fastening position, and a torque-limiting feature prevents over tightening. The method may further include removing a distal portion of the post projecting from the cap and leaving a proximal portion of the post projecting from the cap and which can be deformed to secure the base and cap in the fastening position.

  • Patent number: 6585215
    Abstract: An adjustable, telescoping seat support with suspension that allows the height of a bicycle seat to be adjusted to a number of seat height positions safely while bicycle is in motion. An elongated tubular seat post is clamped to a bicycle frame in a stationary position. A bicycle seat is attached to an end of a tubular seat holder that is slidably posited over the stationary tubular seat post. The tubular seat holder has a coil spring on it that would provide suspension. A coil spring placed inside the tubular seat holder provides an extending force on the tubular seat post and the tubular seat holder such that the seat support is capable of extending to a raised seat position and compressing to a lowered seat position. The seat is locked into raised and lowered seat positions by a plunger locking portion that is attached to the elongated tubular seat holder and which remains at a fixed position relative to the seal for all seat height positions.
