摘要:
An extendable edge reference tool is disclosed. A first segment having a extending end and a receptacle end is provided. The receptacle end includes a coupling mechanism for joining a second segment using an over-center locking force to secure said second segment to said first segment. This tool provides for a useful continuous reference edge over extended distances through adjoining segments. Each segment is suitably compact to be easy stowed. The segments are useful individually. The segments can be joined to extend tool to lengths useful in common construction tasks.

A multi-line chalk reel is disclosed that may be comprised of three or more line reels disposed in a polar arrangement of parallel but distinct rotation axes that has a single method for engaging and disengaging a single drive arrangement to any one spool. This arrangement provides a variety of advantages, including a package solution of useful dimensions and a low part count to minimize parts in assembly. The single drive arrangement reduces cost, and provides for convenient access to individual spools.

Various safety systems for power tools, and in particular table saws include detection systems for detecting a dangerous condition relative to a blade of the power tool, reaction systems for taking mitigation action in response to detection of a dangerous condition. The safety system may detect, prevent, and/or mitigate a dangerous condition associated with the power tool.

A hand-held, low-flow dispenser comprises an enclosure holding a gas cartridge. A spring-biased needle is advanced to puncture a septum on the gas cartridge, and a separate spring-biased ball valve is used to turn the resulting gas flow off and on as well as to control the flow rate.
摘要:
A dual combustion fastener device implements a first combustion event, contained in a first combustion chamber portion to compress a combustible fuel/air mixture contained in a second combustion chamber portion, which is separated from the first combustion chamber portion by a piston including a driver for driving a fastener disposed in the driver's path of travel into a workpiece, in order to generally provide rapid driving power for securing a fastener disposed in a nose guide of the combustion fastener. Ignition of the second combustion event may be timed so that the second combustion event substantially occurs when the piston has achieved top dead center or the maximum compression of the combustible material in the second combustion chamber portion. Utilization of compressed combustible material may allow for the utilization of a piston having a small cross-sectional area in comparison to a typical combustion device while providing equal or greater driving force in a rapid manner.
