Abstract: A carriage assembly for a dispensing tool includes a carriage having an attachment end that is attachable to the dispensing tool and an opposite dispensing end, at least one of an axial opening in the carriage oriented substantially normal to a longitudinal axis of the carriage and a radial opening through which a material-containing cartridge is insertable, a clamp member coupled to a peripheral wall of the carriage and having a portion that protrudes toward the longitudinal axis and that is engageable with a rear end of the cartridge, and a biasing member that exerts a force on the clamp member for biasing the cartridge toward the dispensing end.

Abstract: Power tools, such as, saws and circular saws, and methods. In some constructions and in some aspects, a saw includes a housing, a motor, a cover, and a quick-locking member operable to releasably lock the cover to the housing without tools. In some constructions and in some aspects, a saw includes a housing, a motor, a first cover connected to the housing, the first cover at least partially covering a saw blade, and a second cover selectively connectable to the housing, the second cover at least partially covering the first cover and at least partially covering the saw blade. In some constructions and in some aspects, a method of disassembling a saw including moving a locking member from a first position to a second position without the use of tools, and removing a cover from a housing to at least partially uncover the saw blade.
