ABSTRACT:
A system for repairing breaks in laminated and plate glass utilizing a glass replacement chemical wherein glass replacement chemical is disposed in a dispenser having a dispensing end. The apparatus includes a base and an injector tube supported on the base. A tube opening is formed in a portion of the injector tube with a portion of the tube opening intersecting the lower end of the injector tube and an access opening is formed in a portion of the injector tube with the access opening intersecting an outer peripheral surface of the injector tube and extending a distance through the injector tube and intersecting the tube opening. A seal assembly is supported in the injector tube for sealing the lower end portion of the injector tube to the glass to be repaired with the tube opening being disposed generally over a portion of the break in the glass. An arm assembly is connected to the injector tube for supporting the dispenser so the dispensing end of the dispenser is disposed in the access opening to facilitate the injection of glass replacement chemical into the tube opening. In one embodiment, the apparatus also includes an insert and means for holding the insert in place during the repair process, particularly useful in repairing the plate glass.
