  • Patent number: 10046404
    Abstract: A hand-held band saw for cutting a workpiece. The hand-held band saw includes a deck, first and second wheels coupled to the deck for receiving a continuous blade thereabout, a motor coupled to the deck for driving at least one of the first or second wheels, and a handle providing a grip for a user to hold the band saw. The band saw also includes a blade guard having a first portion adjacent the first wheel, a second portion adjacent the second wheel, and a third portion adjoining the first and second portions. A joint couples the first, second, and third portions to the deck for simultaneous movement of the first, second, and third portions with respect to the deck.

  • Publication number: 20180169851
    Abstract: An interface for a battery pack and an electrical combination. The interface may include a battery-receiving portion configured to receive a battery pack and including a cavity. The cavity is defined by a pair of sidewalls with rails defining a groove between the rails and a lower surface of the cavity. The rails are stepped or angled along a battery insertion axis and are configured to guide the sliding engagement of a battery pack within the battery-receiving portion.

  • Patent number: 9227255
    Abstract: A hand-held band saw having a deck defining a front and a rear, and an opening in the front defining a cut zone. The band saw also includes a first wheel supported by a first deck portion, a second wheel supported by a second deck portion, a motor operably coupled to the first wheel, a single handle providing a single grip for a user to hold the band saw with only one hand, and a continuous blade having a cutting edge. The continuous blade includes a first portion positioned in the cut zone for performing a cutting operation and a second portion positioned outside of the cut zone. A blade guard is positioned proximate the cutting edge of the second portion of the continuous blade to substantially provide a barrier between the cutting edge and an exterior of the band saw.

  • Patent number: 9039557
    Abstract: A powered dispensing tool includes a housing, a motor at least partially positioned within the housing, a rack operably coupled to the motor for powered translation, and a transmission selectively operably coupling the motor and the rack. The transmission includes an output shaft rotatable in response to rotation of the motor, and an output member drivably coupled to the rack and supported on the output shaft for relative rotation therewith. The transmission also includes a clutch member coupled for co-rotation with the output shaft and movable along the output shaft between a first position, in which the clutch member is engaged with the output member for transferring torque from the output shaft to the output member, and a second position, in which the clutch member is disengaged from the output member to inhibit torque transfer between the output shaft and the output member.

  • Publication number: 20110268504
    Abstract: A power trowel for treating a concrete surface includes a support frame configured to be moved on the concrete surface. A propane supply vessel is supported by the support frame and is configured to contain propane. The propane supply vessel is positioned to reduce obstructions to the operator's view of the concrete surface. An internal combustion engine is supported by the support frame and is in fluid communication with the propane supply vessel to receive propane therefrom to power the internal combustion engine. One or more rotatable shafts are driven by the internal combustion engine, and one or more trowel blades connect to the one or more rotatable shafts so as to rotate therewith.
