A sabre saw is provided with a generally tubular saw bar journalled for linear movement in a journal bushing secured in the top portion of the housing and rotatable therein with means provided so that they rotate together. The journal bushing is provided with a generally annular collar in turn provided with a plurality of generally radial notches and a cantilever leaf spring is mounted to the housing with its distal end adjacent the collar and shaped for selective engagement within the notches. A slide trigger is slidably carried by the housing at a top portion thereof convenient to the operator's thumb control which when slid towards the saw bar depresses the cantilevered leaf spring against the collar and into a selective one of the notches when they are aligned for locking the saw bar against rotation. Rearward movement of the trigger slide is effective to release the cantilevered leaf spring wherein it will pop up out of the notch and permit free rotation of the saw bar. Spring biased latching means are also provided for selectively latching the trigger slide in its forward position.
In a sabre saw having a generally tubular saw bar journalled for linear movement in a sleeve bearing secured in the bottom portion of the saw housing and a journal bushing secured in the top portion of the housing and rotatable therein and means provided between the top of the saw bar and the journal bushing so that they rotate together, a generally annular collar surrounding said journal bushing provided with a plurality of generally radial notches, a cantilevered leaf spring mounted to the housing with its distal end adjacent said collar and shaped for selective engagement within the notches, a slide trigger slidably carried by the housing at a top portion thereof convenient to an operator's thumb control which when slid towards the saw bar, depresses said cantilevered leaf spring against the collar and into a selective one of the notches when they are aligned for locking the saw bar against rotation.
