  • BLADE TILT MECHANISMS FOR TABLE SAWS
    Publication number: 20170008189
    Abstract: Blade tilt mechanisms for table saws are disclosed. The disclosed tilt mechanisms provide easy and intuitive operation. They also provide auto-locking so that a user simply releases a component to lock the blade at a specific angle. The tilt mechanisms also provide defined incremental steps for the tilt of the blade and the steps are typically spaced at 1-degree intervals.

  • BLADE ELEVATION MECHANISMS AND ANTI-BACKDRIVE MECHANISMS FOR TABLE SAWS
    Publication number: 20160271710
    Abstract: Elevation mechanisms for table saws and anti-backdrive mechanisms for use in elevation mechanisms for table saws are disclosed. The anti-backdrive mechanisms typically include three sub-assemblies: an input assembly, an output assembly, and a fixed assembly. The anti-backdrive mechanisms prevent a torque related to the output assembly from changing the blade elevation. For example, the weight of the blade and the structure supporting the blade is prevented from backdriving the elevation mechanism and allowing the blade to drop.

  • TABLE SAW INSERT WITH LOCK-DOWN MECHANISM
    Publication number: 20150321271
    Abstract: Inserts for table saws are disclosed. The table inserts are equipped with a toolless locking mechanism that mechanically holds the insert in place and which allows for the installation and removal of the insert without the use of tools. The locking mechanism is easy to lock and unlock and yet robust enough to hold a zero-clearance insert in place.

  • SYSTEMS TO MOUNT AND INDEX RIVING KNIVES AND SPREADERS IN TABLE SAWS
    Publication number: 20150107427
    Abstract: Mounting systems to secure and index riving knives and spreaders in table saws are disclosed. One embodiment may include three mounts or screws attached to an elevation carriage. A clamp plate fits over the heads of the mounts and a handle pivots to move the clamp plate against flanges on the heads of the mounts to clamp a riving knife or spreader in place.

  • INSERTS FOR TABLE SAWS
    Publication number: 20150107430
    Abstract: Inserts for use in table saws are disclosed. One embodiment may include a mechanism to lock mechanically and affirmatively the insert in a blade opening in a table saw. The mechanism is designed so that a user can install and remove the insert without tools. The mechanism also can be designed so that the front of the insert pops up above the table when released from its locked position. The mechanism can be further designed so that the insert can be unlocked or released by a user pressing a button or tab.

  • Mobile base for a table saw
    Patent number: 8511693
    Abstract: A mobile base that attaches to the stand of a table saw is disclosed. The mobile base includes wheels and casters that rotate down and lift the saw when a foot pedal is depressed. The mobile base raises the saw asymmetrically to provide clearance for the legs of an extension table attached to the table of the saw. A locking mechanism locks the wheels and casters so that they do not retract while the saw is moved, and a foot-operated lever releases the wheels and casters so that they may retract and lower the saw back to the ground.

  • Blade guard a table saw
    Publication number: 20120216665
    Abstract: Blade guards for table saws are disclosed. The blade guards can be used in a configuration where the guard holds a work piece against a work surface. This may be thought of as blade guards with hold-down capability. The blade guards also include splitters and anti-kickback assemblies. The anti-kickback assemblies include anti-kickback pawls that can be in an operable configuration or a disabled configuration.

  • Mobile base for a table saw
    Patent number: 8246059
    Abstract: A mobile base that supports a cabinet saw is disclosed. The mobile base includes casters that support the saw when a foot pedal is depressed. The mobile base raises the saw asymmetrically to provide clearance for the legs of an extension table attached to the table of the saw. A hydraulic jack is employed to raise the saw and hold it raised while the saw is moved, and a foot-operated release lever attached to the jack lowers the saw back to the ground at an adjustable rate of descent.
