ABSTRACT:
An adjustably extensible torque-multiplier breaker-bar for applying variable torques to a tool headpiece. The device employs a telescoping inner member received within a sleeve member thus comprising a breaker-bar which permits the user to exploit the advantages of the principles of physics involved. An outer sleeve member carries a slideably adjustable inner member such that both members provide cooperatively for stepped length adjustment so as to shorten or lengthen the overall longitudinal dimension of the telescoping breaker-bar. Such extension and retraction allows a user to modify the mechanical advantage of the tool in accordance with mechanical theories of physics.
