ABSTRACT:
A quick release chuck device for releasably holding a jaw blade includes a body member having an internal longitudinal bore defined therein. The longitudinal bore has a substantially rectangular cross-section shape for receipt of conventionally sized saw blades. At least one radial bore is defined in the body member and is in communication with the longitudinal bore through one of its short sides. An engaging device is disposed in the radial bore and is movable radially within the radially bore so that at least a portion of the engaging device extends into the longitudinal bore in a locking mode of the chuck device to hold a saw blade within the device through contact with a recess defined in the edge of the blade. A spring-biased outer sleeve is disposed about at least a portion of the body member. The outer sleeve is movable longitudinally between a released position and a locking position. The outer sleeve member includes an engaging surface having a portion which contacts the engaging member and forces the engaging member radially inward to engage a saw blade inserted into the longitudinal bore in the locking position of the sleeve member. The device is unlocked by an operator grasping the outer sleeve surface and moving the outer sleeve to its released position thereby allowing the engaging member to move radially outward to release the saw blade.
