Abstract: A device for repairing windshield cracks. A cylinder includes a sealing mouth adapted to contain a quantity of filler material. The mouth with filler material therein is positioned over the crack opening. The cylinder includes a small cavity adjacent the mouth and a larger upper cavity. A plunger fitted to the cylinder carries a lower seal for the small cavity and an upper seal for the larger cavity. Moving the plunger from an initial fully depressed to a fully retracted position opens the small cavity to the upper cavity whereby the vacuum of the upper cavity enhances the evacuation of air from the crack. Subsequent depression of the plunger is assisted by a one-way exhaust valve. Such depression of the plunger produces injection of the filler material into the crack replacing the evacuated air.

Abstract: This invention is directed to an apparatus and method for repairing pock marks and bullseyes in glass such as a windshield and such as plate glass. The apparatus comprises essentially an adapter, a syringe and a polymerizable resin. The adapter is attached to the glass over the pock mark or bullseye. The syringe with the polymerizable resin is positioned in the adapter and the polymerizable resin forced into the pock mark or bullseye.
