Abstract
In the repair of localized zones of damage to laminated safety glass with use of a polymerizable liquid, a T-fitting has one of the opposed legs threadingly received through an internally-threaded central opening in a transparent, hemispherical suction cup adapted to support the fitting in perpendicular alignment with the damaged zone for adjustable seating in sealing contact thereabout. A pierceable, resilient disk at the outer end of the opposite leg of the fitting provides for the insertion therethrough, to reach the damaged zone, of the hollow needle of a medical syringe for mechanically flexing the damaged zone and depositing the polymerizable repair fluid. The transverse leg of the T-fitting connects with a flexible hose for alternately imposing vacuum and applying air pressure to the interior of the fitting to facilitate the withdrawal of air from the damaged zone and substitution of the polymerizable fluid so as to achieve a practically invisible repair.
