  • Patent number: 11577420
    Abstract: A quick-change cutting assembly includes a base having a support surface for supporting a cutting blade, a clamping arm having a clamping surface, a spring interposed between the base and the clamping arm, and a pivot defining a pivot axis between the spring and the clamping surface that couples the clamping arm to the base. The spring biases the clamping surface toward the support surface and a cutting blade therebetween. The clamping arm is pivotable between a closed position where the clamping surface is parallel to the support surface and an open position removed from the closed position where the clamping surface is spaced further from the support surface. The cutting assembly further includes a locking pin transverse the direction of biasing action of the spring that connects the clamping arm to the base to prevent the clamping arm from pivoting relative to the base when in the closed position.

  • Patent number: 11577328
    Abstract: A dust collection system for a circular saw may include an attachment. A fixed blade guard may define an exhaust port for removing debris drawn into the fixed blade guard. An attachment may be positioned adjacent to a fixed blade guard in fluid communication with an interior of the fixed blade guard through an aperture, where the attachment defines an exhaust port. An exhaust port can extend into fluid communication with a cavity formed by a protrusion, where the cavity has an expanded interior volume extending from and adjacent to the exhaust port. A channel defined by a connection configured for connecting to a vacuum source is in fluid communication with the expanded interior volume of the cavity through the exhaust port for pulling debris from within the fixed blade guard into the cavity and through the exhaust port and the channel toward the vacuum source.
