Patent number: 10046404Abstract: 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.Type: GrantFiled: December 11, 2015Date of Patent: August 14, 2018Assignee: MILWAUKEE ELECTRIC TOOL CORPORATIONInventors: Jeffrey Holly, Jeffrey M.

Patent number: 9227255Abstract: 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.Type: GrantFiled: February 28, 2014Date of Patent: January 5, 2016Assignee: Milwaukee Electric Tool CorporationInventors: Jeffrey Holly, Jeffrey M.

Patent number: 9039557Abstract: 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.Type: GrantFiled: August 30, 2012Date of Patent: May 26, 2015Assignee: Milwaukee Electric Tool CorporationInventors: Michael Naughton, Anna M. Kaczmarczyk, John G. Marx, David P. Lincoln, Joseph H. Ellice, Troy C. Thorson
