Abstract
A kit (150) of parts from which tools may be assembled for the repair of glass cracks by insertion of resin having an index of refraction substantially that of the glass. The tools are a repair bridge (160) and a repair bar (180) which may be placed on an automobile windshield and used to inject resin into a glass crack and a crack spreader (170) which may be placed on the inside of a windshield and used to spread the crack to facilitate entry of the resin. Methods of use of the tools are disclosed.
Claims18
The method of repairing a crack exceeding 6 inches in length in a glass layer of an automobile windshield which crack comprises a relatively fight length defining a point portion which terminates in the glass area and a relatively open portion defining a remainder portion which terminates at an edge of the windshield comprising;
- inserting a resin into the remainder portion progressively along the length thereof said resin having a viscosity of at least about 150 c.p.s.;
- inserting a resin into the point portion said resin having a viscosity lower than the viscosity of the resin inserted into the remainder portion.
The method of repairing a crack exceeding 6 inches in length in a glass layer of an automobile windshield which crack comprises a relatively tight length defining a point portion which terminates in the glass area and a relatively open portion defining a remainder portion which extends to the bottom edge of the windshield comprising;
- inserting a resin into the remainder portion progressively along the length thereof said resin having a viscosity in the range from about 150 c.p.s. to about 3000 c.p.s.;
- inserting a resin into the point portion said resin having a viscosity lower than the viscosity of the resin inserted into the remainder portion.
The method of repairing a crack in a glass layer of an automobile windshield which crack exceeds 6 inches in length and comprises a relatively fight portion defining a point portion which terminates in the windshield glass area and a relatively open portion defining a remainder portion which terminates at an edge of the windshield comprising;
- inserting a resin in the remainder portion progressively along the length thereof said resin having a viscosity of at least about 150 c.p.s.;
- inserting a resin in the point portion said resin having a viscosity of less than about 90 c.p.s.
The method of repairing a crack exceeding 6 inches in length in a glass layer of an automobile windshield which crack comprises a relatively tight length defining a point portion which terminates in the glass area and a relatively open portion defining a remainder portion which extends to the bottom edge of the windshield, said remainder portion further defining an edge portion adjacent the edge of the windshield and an intermediate portion between the edge portion and point portion comprising;
- inserting a resin into the edge portion progressively along the length thereof, said resin having a viscosity up to about 4000 c.p.s.
- inserting a resin into the intermediate portion progressively along the length thereof, said resin having a viscosity in the range from about 150 c.p.s. to about 3000 c.p.s and which is lower than the viscosity of the resin inserted into the edge portion;
- inserting a resin into the point portion, said resin having a viscosity lower than the viscosity of resin inserted into the intermediate portion.
