ABSTRACT:
A saw blade clamping arrangement particularly for power reciprocating saws and similar tools having a reciprocating shaft connected to a cutting member includes a biasing member preferably in the form of a spring clamp member. The biasing member is interconnected with the drive shaft and operative for providing a biasing force to retain the cutting member in operative connection with the drive shaft. A release lever is pivotally mounted to a housing of the saw for movement between first and second position. In the first position the release lever is spaced apart from the biasing member. In the second position the release lever engages the biasing member and opposes the biasing force of the biasing member to permit quick and easy removal and replacement of the saw blade. The spring clamp member biases the saw blade into operative engagement with the drive shaft. In a second preferred embodiment, the spring clamp member biases a locking member into engagement with the saw blade. In a third preferred embodiment, the release lever is operative for linearly translating a control member which in turn selectively urges a locking member into engagement with the saw blade.
