Apparatus for repair of shatterproof glass

Apparatus for the repair of conical cracks in shatterproof glass comprising:

• means for cooperating with an area on said glass surrounding a conical crack therein, to provide an enclosure bounded in part by said area;
• and
• means for evacuating said enclosure;
• said means to provide an enclosure including transparent means for permitting the viewing of the conical crack while said means to provide an enclosure is in cooperation with said area to provide an enclosure bounded in part by said area.

Apparatus for the repair of conical cracks in shatterproof glass comprising:

• means for cooperating with an area on said glass surrounding a conical crack therein, to provide an enclosure bounded in part by said area;
• and
• means for evacuating said enclosure;
• said means to provide an enclosure comprising means forming a wall, means for causing said wall to be spaced from said area when said enclosure is bounded in part by said area, said wall being formed in part by a flexible diaphragm, and said apparatus including a sharp probe tip, located within said enclosure, and manipulable means connected to said probe tip through said diaphragm for controlling movement of said probe tip.

Apparatus for the repair of conical cracks in shatterproof glass comprising:

• means for cooperating with an area on said glass surrounding a conical crack therein, to provide an enclosure bounded in part by said area;
• and
• means for evacuating said enclosure;
• wherein said means to provide an enclosure comprises means forming a wall and means for causing said wall to be spaced from said area when said enclosure is bounded in part by said area, said wall having an opening with threads and said apparatus also including a sleeve threaded into said opening and movable toward and away from said area by the action of said threads, annular sealing means on one end of said sleeve adapted to contact the surface of a piece of shatterproof glass to be repaired and thereby isolate a small portion of said area from the remainder thereof, and first control means manipulable from the exterior of said enclosure for rotating said sleeve in order to move the same toward and away from said area, said sleeve having a cylindrical channel in its interior communicating with said one end thereof, a plunger closely fitting the wall of said channel and axially movable therein, and second control means manipulable from the exterior of said enclosure for effecting axial movement of said plunger.
