Embodiments of the present invention comprise a battery charging jobsite audio unit that is particularly useful at construction and other jobsites are disclosed which provides important desirable features and functionality comprise a housing, at least one charger for charging a removable battery pack, an audio unit that includes a speaker system for providing substantially 360&#xb0; sound, as well as subwoofer, a cord and plug for connecting the unit to a source of AC power, and circuitry for selectively applying power to the audio unit and the charger. The preferred and alternative embodiments also preferably have a unique protective frame structure that is connected to the housing of the unit.

Battery charging jobsite audio apparatus

Embodiments are directed to a modular saw guard system for a power saw having a top and a vertically adjustable blade, the system comprises a riving knife mechanism, a blade guard mechanism that is releasably mounted to the riving knife mechanism when the riving knife mechanism is at least in its extended position, the blade guard mechanism generally covering the blade and being adjustable to enable a work piece to be moved into cutting position by the blade and a kickback prevention mechanism that is releasably mounted to the riving knife mechanism when the riving knife mechanism is at least in its extended position, the kickback prevention mechanism being configured to engage a work piece as it is being cut by the blade and apply resistance to prevent the work piece from being expelled in the reverse direction.

Modular table saw guarding system upper guard barrier

A preferred embodiment of the present invention is directed to a modular saw guard system for a power saw of the type which has a table top, a rotatable circular saw blade that is vertically adjustable relative to the table top, wherein the system comprises a riving knife mechanism releasably mounted to the saw rearwardly of the blade, and being configured to be adjustable between retracted and extended positions relative to the blade, a blade guard mechanism that is releasably mounted to the riving knife mechanism and a kickback prevention mechanism that is releasably mounted to the riving knife mechanism when the riving knife mechanism is at least in its extended position, the kickback prevention mechanism being configured to engage a work piece as it is being cut by the blade and apply resistance to prevent the work piece from being expelled in the reverse direction.

Modular table saw guarding system riving knife release mechanisms

A preferred embodiment of the present invention is directed to a modular saw guard system for a power saw of the type which has a table top, a rotatable circular saw blade that is vertically adjustable relative to the table top, the table top having an opening through which the saw blade can extend, the blade being configured to cut a work piece as the work piece is moved forwardly from a forward position to a rearward position, wherein the system comprises a riving knife mechanism releasably mounted to the saw rearwardly of the blade, and being configured to be adjustable between retracted and extended positions relative to the blade, a blade guard mechanism that is releasably mounted to the riving knife mechanism when the riving knife mechanism is at least in its extended position, the blade guard mechanism generally covering the blade and being adjustable to enable a work piece to be moved into cutting position by the blade and a kickback prevention mechanism that is releasably mounted to the riving knife mechanism when the riving knife mechanism is at least in its extended position, the kickback prevention mechanism being configured to engage a work piece as it is being cut by the blade and apply resistance to prevent the work piece from being expelled in the reverse direction.
