ABSTRACT:
The inertial hammer of the invention includes a spherical mass and a handlebar. The bar runs along a diameter of the spherical mass and extends a predetermined distance from each side of the mass so that an operator may grasp one end of the bar in each hand. The mass and bar comprise what is herein referred to as inertia producing means. A loop or eye is attached to the spherical mass. A first flexible connector is attached between the eye and an object to be repaired. A second flexible connector is attached between the inertia producing means and an anchor. The second flexible connector is of a predetermined length so that when the hammer is operating and the first flexible connector is fully extended, the second flexible connector is in a slack condition. The connectors are attached to the damaged part and anchor by an attachment device. The second flexible connector acts as a safety connection to stop the motion of the mass in the event the first flexible connector breaks free of the object.
