  • Patent number: 8366592
    Abstract: An automated tool includes a quick change spindle assembly. In another aspect of the present invention, the quick change spindle includes an attachment assembly for interchangeable fastener drivers. A further aspect of the present invention employs release member to actuate a drive member in the spindle assembly causing a retainer to uncouple a fastener driver with the spindle.

  • Patent number: 7237990
    Abstract: A surgical tool system with a handpiece and a cutting accessory that has inner and outer hubs. The handpiece has a spring biased lock ring that abuts a complementary stop member integral with the accessory outer hub to hold the accessory to the handpiece. An RFID chip is disposed against an inner wall of the accessory outer hub. An elastomeric seal pressed against the inner wall of the accessory outer hub provides environmental protection for the RFID chip. The seal has a rib that extends around the outer perimeter of the proximal end of the outer hub so as to form a seal between the accessory and an adjacent inner wall of the handpiece. Stop tabs extend inwardly from the seal to prevent the drive hub disposed inside the outer hub from falling out.

  • Patent number: 6733218
    Abstract: A high speed surgical instrument is designed with a clutch that automatically locks a cutter which is easily assembled and disassembled without moving parts. The clutch includes a pin and U-shaped pin that compliments a configured groove section at the proximal end of a cutter that fits into a clutch mechanism in the drill or attachment. The cutter includes axially spaced and opposed grooves judiciously located and a flat end portion that allows easy ingress and egress for locking into the clutch mechanism. A square or multi-sided bore configuration of a journal type bearing made from a high temperature resistance polymer material allows the drill to operate at high speeds with a reduction in the diameter of the distal end of the cutter support.

  • Patent number: 6604744
    Abstract: A novel drill bit adapter includes a body portion, a cap portion, a spring-biased catch and a push button actuator. The cap portion includes a transverse aperture and cooperates with the body to define a longitudinal aperture and a catch-receiving cavity. The push button is disposed in the transverse aperture and engages the catch to move the catch in the cavity relative to the longitudinal aperture in opposition to a biasing force supplied by the spring. The spring is a wire spring that extends longitudinally from the body portion into the cap portion to engage the catch.

  • Patent number: 5638729
    Abstract: A boring bar holder for use with a lathe has a massive metal block with a generally triangular cavity extending transversely across the block. Inside the cavity a pair of diagonally extending surfaces are defined by the inside of upper and lower walls which intersect one another along a centering line. A U-shaped clamp rides in longitudinal grooves on sides of the block providing legs that have contact surfaces on ends of the legs. When the U-shaped member is forced forward, ends of the legs and the upper and lower wall grip the boring bar from three sides, causing the bar to be forced into position parallel to a centering line. A wide size range of boring bars can be held by this device with minimal adjustment, and change-out of bars is readily carried out when needed.

  • Patent number: 4916867
    Abstract: The present invention provides a drill bit sharpening device, for use with a support carrying a rotatable grindstone and having pivot arm retaining means. The device comprises a drill bit jig having clamp means for releasably retaining a drill bit therein in a position wherein the drill bit axis extends forward from the clamp means along a corresponding clamp axis. The clamp means has a first and second opposed jaw movable toward and away from one another so as to accommodate different diameter drill bits positioned therebetween. A jaw adjuster connected to the first jaw has a U-shaped frame with upper and lower threaded flanges extending over the second jaw. A nut adapted to mate with the threaded flanges is provided for securing the drill bit. A retaining guide is connected to the second jaw and is adapted to urge the second jaw away from the first one.

  • Patent number: 4553306
    Abstract: A modification to an existing adapter for reciprocating saber saws which supports the saw blade on the top of the adapter for making "flush with" cuts along the intersection between floors and walls, the improvement providing a second mounting for the saw blade clamping clip on the side of the adapter for making "flush to" cuts in a floor perpendicular to a wall with the cut ending at the wall.

  • Patent number: 4054294
    Abstract: Rotary motion is converted to linear motion by multiple thread sets which cooperate to provide precise control of the amount of rotary motion thus converted. As applied to a precision positioning device for a tool, blade or other object, the thread sets are preferably arranged in a serial and/or telescoped configuration. A relatively simple precision hand tool positioning device is realized by having one thread set arranged in a common direction but reduced pitch relative to the other set. The finiteness of the object positioning is further enhanced by moving it with respect to an inclined plane. A retaining device for gripping the element to be moved is directly associated with a shank having the smaller pitched thread set thereon. The shank is prevented from rotating but allowed to move linearly relative to a housing and the threads thereof engage a spindle which has another set of threads for engaging the housing. A calibrated indicator of the shank position in easily readable format is provided.
