Abstract: A shroud of a vacuum cleaner that includes a housing supporting an impeller configured for creating a working airflow path between a dirty air inlet and an exhaust outlet. The shroud includes a forward wall having a shroud inlet, an annular axial wall, and an opening formed in the annular wall. The shroud inlet is configured to be aligned with an inlet of the impeller inlet along an axial direction, and the annular axial wall extends away from an outer perimeter of the forward wall along the axial direction. The opening is configured to be arranged in line with a portion of the exhaust outlet along the radial direction. The annular axial wall and the opening define an overall circumferential perimeter of the shroud. The annular axial wall occupies more than half of the overall circumferential perimeter, and the opening occupies less than half of the overall circumferential perimeter.

Abstract: A reciprocating tool includes a housing, a spindle having an end configured to receive a saw blade, and a blade clamp mechanism supported on the spindle and configured to attach the saw blade to the spindle. The blade clamp mechanism includes a locking member movable relative to the spindle between a locked position and an unlocked position. The blade clamp mechanism also includes an actuating member that is rotatable relative to the spindle between an engaged position and a released position. The actuating member defines a gripping surface with ridges and includes a first tab and a second tab, each of the first tab and the second tab protruding radially from the outer gripping surface.
