US 2004/0068876 A1 · Clamping arrangement for receiving a saw blade in multiple orientations

Abstract

A saw blade clamping arrangement for a power tool includes a clamp support, a biasing member and an actuation member. The clamp support is interconnected with the drive shaft for reciprocating motion with the drive shaft relative to a housing of the power tool. The clamp support is configured to selectively receive a saw blade of the power tool in various orientations. A release lever is carried by the housing and is manually rotated to move a control member between a first position in which the saw blade is coupled to the drive shaft and a second position in which the saw blade may be displaced from the drive shaft. In at least one of the orientations, the saw blade is positioned offset from the drive shaft and proximate one of the side walls of the tool housing to allow for flush cutting of a work piece.

A saw blade clamping arrangement for a power tool including a housing, a drive shaft mounted for reciprocating motion relative to the housing, and a saw blade releasably interconnected with the drive shaft for reciprocating motion along a longitudinal axis, the saw blade clamping arrangement comprising:

a clamp support interconnected with the drive shaft, the clamp support configured to selectively receive the saw blade in at least two mutually perpendicular orientations;
and
a control member connected to the clamp support, the control member including a first portion for selectively creating an operative connection between the saw blade and the drive shaft when the saw blade is received by the clamp support in a first of the at least two mutually perpendicular orientations, the control member further including a second portion for selectively creating an operative connection between the saw blade and the drive shaft when the saw blade is received by the clamp support in a second of the at least two mutually perpendicular orientations.

a clamp support interconnected with the drive shaft, the clamp support configured to selectively receive the saw blade in at least two non-parallel orientations;
a control member connected to the clamp support, the control member for creating an operative connection between the saw blade and the drive shaft when the saw blade is received by the clamp support in any of the at least two non-parallel orientations, the control member movable between a first position for creating the operative connection and a second position permitting removal of the saw blade;
and
a release lever for mounting to the housing, the release lever normally spaced from the control member and manually movable to engage the control member and displace the control member from the first position to the second position.
