  • Windshield repair assembly
    Patent number: 4681520
    Abstract: A repair assembly for the in-place repairing of windshields and the method for using such assembly, wherein a repair material injected into the windshield break area by a syringe and needle is forced into the windshield break through the repair assembly secured and sealed to the windshield by first applying stepped increments of measured vacuum levels and visually monitoring the windshield break area, and second applying positive pressure to the windshield break. An ultraviolet light source completes the repair by expediting hardening of the repair material within the windshield break to prevent refraction of light at the windshield break.
