摘要:
Cutting machines with high-speed safety systems, and actuators used in high-speed safety systems, are disclosed. The cutting machines may include a detection system adapted to detect a dangerous condition between a cutting tool and a person. A reaction system performs a specified action, such as stopping the cutting tool, upon detection of the dangerous condition. An actuator may be used to trigger the reaction system to perform the specified action.

The invention is a garbage disposal that includes a dishwasher drain connection to allow water and waste to enter the disposal from a dishwasher, a water input port also to allow water to enter the disposal, a valve associated with the water input port to block the flow of water through the water input port until the valve is actuated, and a switch assembly to actuate both the disposal and the valve. In one embodiment of the invention a coupler is connected to the dishwasher drain connection, where the coupler accepts both a dishwasher drain hose and a water supply hose, so that the dishwasher drain connection acts as the water input port. Another embodiment of the invention includes a coupler adapted to be installed on and modify existing disposals according to the invention. The invention also includes a method of modifying garbage disposals according to the invention.

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.

摘要:
A table saw having a reaction system configured to take a predetermined action to mitigate injury upon detection of a dangerous condition is disclosed. The reaction system has a component in a predetermined orientation relative to the blade and the component is configured to maintain its orientation relative to the blade as the blade is raised and lowered.

Throat plates for table saws and table saws including the same are disclosed. In some embodiments, the throat plates and/or saws include at least one securement mechanism adapted 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 includes 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.

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.
摘要:
Elevation mechanisms for table saws are disclosed. Embodiments include mechanisms with an elevation carriage, a trunnion structure, and a shaft with a cantilevered portion. The shaft can be fixed to one of the elevation carriage and trunnion structure, and the other of the elevation carriage and trunnion structure slides on the cantilevered portion.
摘要:
Table saws having a mounting system configured to hold a riving knife or splitter adjacent a blade. The mounting system includes a clamping structure having a handle adapted to pivot between a first position where the clamping structure is open and a second position where the clamping structure is closed, and where the handle can be pivoted from the first position to the second position by hand without using tools. The clamping structure may include a spring to help open the clamp.
摘要:
Brake pawls for use in safety systems for power equipment are disclosed. The brake pawls include an energy-absorbing region. The energy absorbing regions may include a deformable or collapsible region made from apertures in the brake pawl or from collapsible members or from materials of differing hardnesses, strengths, or structures.
