Patent ID: 7121007

Claim:
A windshield removal assembly for cutting a urethane bed securing a glass windshield having a curved surface to a vehicle at an edge of a windshield opening formed by the vehicle, there being a narrowing apex space between the windshield and a vehicle part forming the opening, comprising: a reciprocating air gun; a rigid, elongated shaft having inner and outer ends and being connected at its inner end with the gun for reciprocation thereby; and a flat thin steel blade of substantially constant thickness, said blade having front and rear ends, the blade rear end being connected to the shaft's outer end, the blade being substantially coplanar with the shaft, the blade having a substantially straight front edge which is beveled on one side only to provide a non-sharpened top edge and a sharpened bottom cutting edge, the blade narrowing from its front end to its rear end to about the width of the shaft, the blade being sufficiently rigid to cut the urethane bed when reciprocated by the air gun but having sufficient lateral flexibility to conform to the curved surface of the windshield when pressed there against; the shaft being operative to space the blade from the gun sufficiently to allow the assembly to be used within the confines of the apex space; the air gun being operative to reciprocate the shaft and blade with sufficient force to advance the blade through the urethane bed; the blade being configured so that the non-sharpened top edge of the blade can be pressed against the glass of the windshield while the sharpened bottom cutting edge penetrates the urethane bed.
