  • Patent number: 7437824
    Abstract: A reciprocating saw includes a locking mechanism for a shoe of the reciprocating saw. The mechanism includes a lever mounted on the saw body movable to a first position where the saw blade is clamped in place. It also includes a lock pin with a body, a reduced circumference section, and a pin shoulder adjacent the reduced circumference section. The pin has a locked position where the pin shoulder abuts the shoe shoulder whereby the pin locks the shoe in place and an unlocked position where the shoe shoulder may translate through the clearance defined by the reduced circumference section. The lever urges the pin toward the locked position when the lever is in the first position.

  • Publication number: 20060171820
    Abstract: A portable air compressor assembly includes a tubular frame having side sections and an assembly longitudinal axis. A support plate between the side sections supports a power unit having a longitudinal axis arranged perpendicular to the assembly longitudinal axis. A compressor having a compressor head and longitudinal axis is mounted to the support plate with the compressor longitudinal axis parallel to the power unit longitudinal axis and perpendicular to the assembly longitudinal axis. A fan connected to the power unit generates an air flow. A ducted cover enclosing the fan includes an air passage directing the air flow from the fan to the compressor head. The ducted cover includes inner and outer covers each including a portion of the air passage. An air scoop extends into the outer cover portion of the air passage to redirect the air flow.
