Abstract
Abstract A SABER SAW DEVICE FOR ATTACHMENT TO A STANDARD DRILL MOTOR CONVERTS THE ROTARY MOTION OF THE DRILL MOTOR TO RECIPROCATING MOTION OF A SAW BLADE. THE BLADE IS LOCKED TO THE RECIPROCABLE MECHANISM IN A MANNER TO PREVENT INADVERTENT DISENGAGEMENT OF THE BLADE WHILE THE SAW IS IN OPERATION. THE BLADE AND RECIPROCABLE MECHANISM ARE COMPATIBLY DESIGNED SO THAT EITHER A SINGLE ENDED OR DOUBLE ENDED BLADE MAY BE MOUNTED ON THE DRIVING MECHANISM.
