Abstract
A convertible repair device arranged to repair bulls-eye type cracks and elongate cracks in a laminated glass. The device has a stepped housing that has a large cylinder and a small cylinder. A piston is mounted in the housing and is movable in the cylinders. A mouth formed in the small cylinder is arranged to receive the filler material. The device is arranged to withdraw air from the bulls-eye type crack by moving the piston upward. When the air is withdrawn the piston is moved downward and the filler material flows into the crack. The piston has a thread form on its upper portion and a plunger projected into the thread form provides controlled movement of the piston without imparting a force on the surface of the laminated glass which is beneficial for filling elongate cracks.
