ABSTRACT:
An apparatus for repairing breaks in safety glass, such as that found on automotive windshields, includes a self-contained, small fixture which can be secured to the windshield and centered on the break. The fixture includes connections for applying a vacuum source for evacuating the break, and for connecting a self-contained and self-supported measured quantity of resin to the fixture so the resin will enter the break while the break remains under a vacuum. The introduction of the resin into the break is thus enhanced, because the break is under vacuum. When vacuum is released, pressure may be applied to the resin to force it into the break to completely fill the break and provide for a visually acceptable repair. Curing of resins can then be carried out in a conventional manner.
