Abstract: A riving knife assembly has a holder, a clamping plate, a riving knife body disposed between the holder and the clamping plate, a handle pivotally connected to the clamping plate, and a fastener assembly connecting the holder, the riving knife body, the clamping plate, and the handle. The handle has a curved hole and a stage surrounding the curved hole and having a lower step and an upper step. The fastener assembly includes a connecting rod, a positioning flange, and an elastic pressing element. When the handle is in a locked position, the elastic pressing element is located between the positioning flange and the upper step of the stage to clamp the riving knife body. When the handle is in an unlocked position, the elastic pressing element is located between the positioning flange and the lower step of the stage to release the riving knife body.

Abstract: Table saws and table saws designed to implement safety systems that detect contact between a person and a dangerous portion of the saw are disclosed. Table saw components, mounting systems for table saws, and table saw attachments are also disclosed. One embodiment may include a first clamp surface, a second clamp surface spaced apart from the first clamp surface so that a base portion of a riving knife or splitter can be placed between the clamp surfaces with the opposing sides of the base portion generally parallel to the first and second clamp surfaces.

Abstract: A table saw includes a height adjustment wheel including a threaded shaft; a blade suspension mechanism secured to a lock crank; a rod secured to both the blade suspension mechanism and a bottom of the cutting surface; an electric motor including a driving shaft and a link extending forward to secure to the blade suspension mechanism; a circular saw blade operatively connected to the driving shaft; first and second mounting plates each secured to the link and including a slanted slot element; and an interconnection including two end holes moveably disposed in the slot elements of the first and second mounting plates respectively, and an intermediate threaded hole secured to the threaded shaft. A rotation of the height adjustment wheel moves the saw blade up or down.

Abstract: A power table saw has a saw blade driven by a motor with power selectively supplied to the motor by actuation of a switch. A riving knife is selectively positioned in an extended position and a retracted position relative to the blade. A blade guard is removably mounted to the riving knife above the blade. A sensible element on the riving knife can be detected by a first sensor when the riving knife is retracted, the first sensor has a non-null state when the sensible element is adjacent the first sensor and a null state otherwise. A second sensor has a null state when the blade guard is detected and a non-null state otherwise. A controller determines the states of the sensors and disengages power to the motor when the switch is actuated when the states of the sensors are different.

Abstract: An apparatus for fixing a saw blade and a knife plate of a saw grinding machine includes a driving device including an axis; and a fixture plate having a first end and a second end. The fixture plate includes a connective hole coupled to the driving device, and a coupled portion defined at the first end thereof. The saw blade is pivotally connected to the axis of the driving device, with the saw blade and the fixture plate moved with respect to the driving device simultaneously. The knife plate is coupled to the coupled portion of the fixture plate and includes a blocked side formed on a side thereof, with a vertical distance between the blocked side and the saw blade maintained to be fixed.
