    Abstract: A guard for a table saw has a cover member positioned above a working surface and rotating blade of a table saw. The cover member provides a gap between a lower surface of the cover member and the working surface to permit a work piece to pass there through to be cut by the rotating blade. The guard has at least one support member for supporting the cover member above the working surface. The support member facilitates lateral movement of the cover member between a first position and a second working position. The lateral movement is generally parallel to the working surface. The cover member covers the rotating blade from above throughout the cutting operation.

  • Patent number: 6748838
    Abstract: A table saw having a rotation structure includes a work table, a suspension rod, a swing seat, a rotation seat, a push lever, two torsion springs, and a threaded rod. When the threaded rod is rotated, the push lever is displaced horizontally to push the rotation seat to rotate, so that the circular blade is moved upward, thereby adjusting the cutting height of the circular blade. Thus, the push lever is urged by the elastic force of the two torsion springs, so that the push lever is closely and rigidly combined with the threaded rod, thereby eliminating the clearance between the push lever and the threaded rod, so that the cutting height of the circular, blade is adjusted exactly and precisely, thereby enhancing the cutting efficiency of the table saw.

  • Patent number: 6595096
    Abstract: A machine tool has a work table which defines a working surface and has a cutting tool which is attached to and movable with respect to the work table. The position of the cutting tool with respect to the working surface is controlled by a mechanism which elevates the cutting tool with respect to the working surface and angulates the cutting tool with respect to the working surface. The cutting tool is mounted to a support plate which is pivotably attached to the work table. The elevating mechanism includes a threaded rod and a nut which engages a pivoting link. The pivoting link also engages the cutting tool. Rotation of the threaded rod pivots the link which in turn raises and lowers the cutting tool. A spring biases the cutting tool towards its lower position to remove play between the components. The angulating mechanism includes a lever, two cams and a locking rod. Rotation of the lever moves the locking rod longitudinally due to the action between the two cams.

  • Patent number: 6591724
    Abstract: This invention is an improved structure for saw clip. On the working desk, there is a lead trough. On the pivot of this working desk, there is a block section for items to wait to be sawed. A top pusher block, when moved onwards, can be used to fix the items so that the sawing process can go smoothly. Among the parts of this invention, there is a sliding trough on top of the block and the sliding trough and the lead trough go across each other. Moreover, a lead screw goes through both the sliding trough and lead trough. The lead screw can be adjusted to be at any position in the lead trough to change how the block is placed. Then, the block can be screwed tightly so that it will not turn upon receiving the pushing force from clipping.

  • Patent number: 6584698
    Abstract: An angle indicating apparatus includes a rod member, an indicia member, an indicator, a spring-loaded tumbler unit, and a locking unit. The indicia member is mounted pivotally on the rod member about a pivot axis, and includes a base plate formed with a generally semi-circular cutout. The indicator is disposed in the cutout and points to angle indicia that are provided on the base plate adjacent to the cutout. The base plate is further formed with a curved guide slot, and has a bottom side formed with a plurality of angularly spaced apart positioning grooves. The spring-loaded tumbler unit is mounted on the rod member and engages removably a selected one of the positioning grooves. The locking unit passes through the guide slot and is operable so as to engage the rod member and arrest undesired rotation of the indicia member relative to the rod member.

  • Patent number: 6578461
    Abstract: The combination of a rip fence and a workpiece pusher are provided for a table saw or shaper. A preferred workpiece pusher moves along a track having a central portion aligned with the feed direction and having two end portions skewed with respect to the feed direction so that the workpiece pusher retracts into the rip fence at both limits of its travel. This allows a sawyer to retract the workpiece pusher on the infeed side of a table saw and begin a ripping operation in which he or she manually pushes the workpiece into the saw blade until the trailing end of the workpiece is close enough to the saw blade that the workpiece pusher can be moved out of the fence to engage the trailing end of the stock. The pusher can then be used to push the workpiece the rest of the way past the blade. This apparatus also allows a woodworker to operate a table-mounted cutting tool without using a workpiece pusher of the invention that is installed on that table.

  • Patent number: 6578460
    Abstract: A blade guard and lifter therefor surround the saw blade, interlocking when raised by a workpiece as a result of relative movement caused by a secondary linkage. Two pair of primary linkages pivotally connect the blade guard to the splitter. The dual secondary linkage pivotally attaches the parallel plates of the lifter to one of the two pivot points of the primary linkages. Any lifting force is resisted by the rigidity of the primary link that does not share a pivot point with the secondary linkage. A dust collector can be provided to the table saw to minimize respiratory hazards.
