ABSTRACT:
Means and methods are provided for the in situ repair with liquid resin of shatterproof windshields and the like. An apparatus is provided which is composed of a plate disposed at the top portion of a preferably rectangular housing which supports a novel injector assembly and pressure assembly. The support plate is pivotally interconnected to the top portion of the housing preferably by a pair of hinges disposed on each of the housing's longitudinal sides. The housing is secured to the surface of the windshield by a vacuum created by the action of a membrane-handlebar assembly. The injector assembly is disposed perpendicularly of and axially through one of a plurality of ear-like apertures. The apparatus is adapted to enable convenient adjustments to the pitch and elevation of the injector assembly with respect to the surface damage, accordingly provide a means and method to maintain the requisite pressures upon the liquid resin as it is transported through the injector assembly to the seal-damage interface. The holding power of the injector assembly derives from the leverage action inherent in the concept of the present invention.
