A shatterproof windshield repair device comprising a housing and a diaphragm. Under vacuum, air passages between the diaphragm and the glass surface form part of a first enclosure which can be evacuated and thus the device is held in place around conical cracks in the windshield. The vacuum in the first enclosure can be maintained by an assembly with a sealing capability. Surrounded by this first enclosure is a second enclosure which directly encircles the immediate area containing the conical cracks in the shatterproof windshield. A separate sealing lip, being part of the diaphragm, encircles this immediate area on the windshield and completely isolates the second enclosure from the first enclosure. In the center of the device is a cylindrical passage that axially extends from the exterior of the housing into the second enclosure. A piston assembly can move in and out of the cylindrical passage to introduce the repair liquid into the conical cracks in the shatterproof windshield.

Apparatus for the repair of cracks in glass such as windshields utilizing repair liquid injected into said cracks, said apparatus comprising: a. a housing adapted for engaging said glass and having a passage formed therethrough for receiving said repair liquid; b. means for engaging the glass and defining a first enclosure, said means comprising a diaphragm having a first peripheral sealing lip and a second inner sealing lip defining a first area of said first enclosure therebetween; c. means for evacuating said first enclosure for producing a vacuum therein, said evacuating means being removably attached thereto; d. means for maintaining said vacuum in said first enclosure when said evacuating means is removed; e. a second enclosure defined by said inner sealing lip and completely isolated from said first enclosure, said second enclosure being in flow communication with said passage; and f. a piston, movable within said passage, for pressurizing and evacuating said second enclosure.
