Patent ID: 7908949

Claim:
A windshield removal assembly for cutting a urethane bed securing the perimeter of a glass windshield to a vehicle at an edge of a windshield opening formed by the vehicle, wherein the windshield has a curved surface and wherein there is a narrowing apex space between the windshield and a vehicle part forming the windshield opening, the assembly comprising: a reciprocating power tool; a cutting blade; a rigid elongated shaft having inner and outer ends, the inner end being adapted for connection with the power tool for reciprocation thereby, and the outer end being adapted for connection to the cutting blade; the cutting blade being a flat, thin metal blade having: a front end and a rear end, the blade front end being substantially straight and being wider than the blade rear end, the blade rear end being adapted for connection through a shank portion of the blade to the shaft's outer end such that the blade is held substantially co-planar with the shaft; straight side edges which narrow from the front end to the rear end to about the width of the shaft, the blade shank portion having spaced shank side edges substantially parallel with the shaft, and wherein the blade side edges meet the shank side edges at an angle between 5 and 25 degrees, an arc portion between the front end and each side edge, the arc portion having a radius of curvature between about 0.60 and 1.0 inches; a non-sharpened top edge on the front end and arc portions, the top edge being configured such that it can be pressed against the windshield; a sharpened bottom cutting edge formed on and extending across the front end of the blade and along at least half of the arc portions adjacent the front end, the bottom cutting edge being sufficiently sharp to penetrate the urethane bed when reciprocated with sufficient force from the power tool; and sufficient rigidity to cut the urethane bed when reciprocated, but sufficient lateral flexibility to conform to the curved surface of the windshield when pressed thereagainst; and the shaft having a length sufficient to space the blade from the power tool to allow the assembly to be operated within the confines of the apex space.
