ABSTRACT:
A device for repairing laminated glass by inserting a liquid, curable resin into the fracture in the glass. An absorbent material is attached to the bottom of a suction cup. When it is desired to commence a repair, several drops of the resin are placed in the absorbent material. The suction cup is then positioned over the fracture such that the absorbent material is aligned with the center of the damage. Then the center of the suction cup is depressed toward the glass until resin flows from the absorbent material. To expedite the repair process, the vacuum between the suction cup and the glass may be intensified by pulling the center of the suction cup farther from the glass without detaching the edge of the suction cup; the center is maintained at this distant location for several seconds before being returned to its original position; and the pulling and returning is repeated several times. This process may be facilitated by attaching a handle to the top of the suction cup. And the cyclical variation of the vacuum may alternatively be achieved by withdrawing and depressing the plunger of a syringe whose nozzle has been inserted in a channel that has been formed to run from the top to the bottom of the suction cup.
