Claims15
A windshield lift for applying pressure on the inside surface of a windshield comprising a base member, first and second cylindrical members, said first cylindrical member telescopically supported with respect to said second cylindrical member for reciprocating motion to extend and retract said cylindrical members with respect to each other, means on an end of said second cylindrical member remote from said first cylindrical member for pivotally mounting said second cylindrical member on said base member, an end of said first cylindrical member remote from said second cylindrical member supporting a bracket, an elongated support member having first and second ends, said first end being pivotally mounted on said bracket, said second end supporting means to frictionally engage said windshield inside surface;
- and means to extend said cylindrical members.
A windshield lift for removing a windshield from a vehicle frame by applying pressure to a surface of the windshield comprising a base member for positioning on the floor of a vehicle, a telescoping lift comprising at least two telescoping sections including a fixed section and a movable section, drive means to reciprocate one of the sections with respect to the other, the fixed section being pivotally mounted on said base member so as to angle the lift in the direction of the windshield, a support bracket mounted on the free end of said movable section, a T-shaped work holder having the stem of the T pivotally and removably mounted on said bracket;
- and a suction cup mounted on each end of the crossarm of the T-shaped work holder.
A method for removal of a vehicle windshield from a vehicle frame wherein said windshield is bonded to said frame by means of a peripheral plastic seal including a top portion, side portions and a bottom portion, said method comprising the steps of:
- installing an adjustable lift acting to supply a force against the internal surface of the windshield;
- gradually increasing the force applied to the windshield until the first sign of stretching of the seal is noticed;
- cutting the top portion of the seal while in a stretched condition;
- slowly increasing the force on the window stretching the side portions of the seal;
- freeing the side portions of the seal;
- with top and side portions of the seal free continue applying force to the windshield pivoting the windshield around its bottom edge;
- cutting the bottom portion of the seal;
- and
- removing the windshield.
