A wrenchless clamp assembly is provided to secure a tool disc, such as a circular saw blade, to a shaft of a power tool. The blade clamp assembly includes an outer flange positionable against an outer side of the blade and a manually tightenable click bolt that includes a movable click member operable to selectively engage the outer flange for rotationally locking or unlocking the bolt. In an embodiment, the click member moves alternatingly between axially engaged and disengaged positions according to sequential rotational increments of the click member relative to the bolt body. Accordingly, the click bolt can be installed by hand and rotationally locked without a need for high torque, and the click bolt can be easily removed by hand when the click member is moved to the disengaged position, axially free from the outer flange. In an embodiment, the click bolt permits limited torque applied during installation.

The invention is an automated sprayer for spraying the walls of a bath and shower enclosure with a cleanser. The sprayer has a housing that can be mounted inside the shower enclosure and that defines a tray in which an inverted bottle of cleanser is stored. The bottom of the tray has a tube extending downwardly along a longitudinal axis through which the cleanser can pass. A motorized head disposed beneath the tube can be rotated about the axis for metering cleanser from the bottle and spraying cleanser outward. The sprayer includes timer circuitry that delays commencement of a spray for a set time and automatically stops spraying after a predetermined period. The sprayer also includes a system for signaling the beginning of a spray cycle including audio and visual alarms. An automated method of cleaning the shower enclosure is also disclosed.

A circular saw includes a clutch assembly to surround the rotating blade shaft of the saw. The blade shaft is rotated by a shaft having a gear at one end. The clutch assembly includes a clutch gear to engage with the rotating pinion. The clutch gear is held to the blade shaft by a shaft washer that has a frictional material laminated to one end. The shaft washer is pressed to the clutch gear by spring washers.
