  • Patent number: 10882207
    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.

  • Patent number: 10442108
    Abstract: Table saws are disclosed. The table saws can include a blade, an arbor, an arbor block, an elevation carriage, and a latch that connects the arbor block and the elevation carriage. The arbor block can have a first position in which the latch connects the arbor block and the elevation carriage, and a second position in which the latch does not connect the arbor block and the elevation carriage. The arbor block can pivot from the first position to the second position upon the occurrence of a retraction force. The table saw can include an actuator to cause the occurrence of the retraction force, and detection electronics to detect contact between the blade and a person. Woodworking machines with detection and reaction systems are also disclosed. A reaction system can include an explosive that causes retraction of a cutting tool.

  • Patent number: 10442106
    Abstract: Extension rails for table saws are disclosed. Some of the disclosed extension rails can be attached to a table saw without a user having to manipulate a lever or knob. Extension rails particularly relevant to portable table saws such as jobsite and bench-top table saws are disclosed, including extension rails that can provide 48? or more of cutting capacity on jobsite and/or bench-top table saws. A method of attaching extension rails to a table saw is disclosed that does not require the use of a tool or the manipulation of a knob or clamp.

  • Patent number: 10335972
    Abstract: Table saws with safety systems are disclosed. The safety systems detect and react to dangerous conditions, such as contact between the blade and a person. The table saws may include a switch, a first light that illuminates to indicate the safety system is operable, and a second light that illuminates to indicate that the safety system is inoperable. The switch may not power the saw when switched on if the second light is illuminated.

  • Patent number: 9878380
    Abstract: Throat plates for table saws and table saws are disclosed. In some embodiments, the throat plates and/or saws have at least one securement mechanism to secure and prevent inadvertent removal of the throat plate from the throat of the saw. In some embodiments, at least one of the securement mechanisms also provides a height adjustment mechanism and/or prevents vertical removal of the throat plate. In some embodiments, the throat plate has an accessory mounting port that provides a portal for accessories, including safety accessories, to extend through the plate from beneath the table of the saw. In some embodiments, the port extends from the plate's outer perimeter to divide the plate's rear end portion into a pair of spaced-apart members. In some embodiments, these members are independently secured to the table saw and retained apart from each other by one or more of the securement mechanisms.
