US Classification:

30380

Abstract:

A portable band saw includes a serviceable/replaceable bumper system for allowing the band saw to be easily repaired if damaged from being dropped. An auxiliary handle is adjustably mounted to the band saw and is releasable from its position if subjected to a large force so as to avoid damage to the handle and tool housing. An adjustable guide shoe includes a toolless adjustment. The front and rear section of the band saw are disposed on opposite sides of a polymeric field case. Compression rods are used to isolate compression forces from the polymeric field case. An electric box assembly including a plastic component box is disposed between the field case and a front section of the band saw. A crash guard is mounted adjacent to the field case and includes a sight guide along an edge thereof and a rear blade guard formed integrally therewith.

Abstract:

A chuck for a power tool includes a body extending along a longitudinal axis, a central bore extending along the longitudinal axis and configured to receive a tool bit, a plurality of angled passageways defined in the body, and a plurality of jaws at least received in the passageways and moveable between an axially forward and radially inward clamping position to clamp a tool bit and an axially rearward and radially outward retracted position. At least one jaw has a rear end lying in a first plane transverse to the longitudinal axis. A first key drive member is coupled to a tail portion of the body and configured to be engaged by a second key drive member on an output shaft of a power tool to non-rotationally couple the body to the output shaft. The first key drive member extends axially from a rearward end to a forward end that lies in a second plane transverse to the longitudinal axis. The second plane is axially forward of the first plane when the jaws are in the retracted position.
