  • Method and device for removing windshields
    Patent number: 6616800
    Abstract: A needle is inserted through the glue between a windshield and a frame surrounding the windshield. Two ends of string are inserted from an outside of the windshield to an inside thereof. One end is attached to a first hand tool so that the string forms an acute angle with the bottom end of the windshield. The end is pulled until the string cut through the windshield adhesive and moves along the edge of the windshield and forms a right angle with the edge of the windshield. The other end is attached to a second hand tool and pulled until the other end also forms a right angle. The hand tools are then moved so that the string again forms acute angles. The string is pulled until the string has been pulled along the entire circumference of the windshield and the windshield may be removed.
