Abstract
An apparatus for removal of a windshield wiper arm or bracket and blade assembly from a threaded stud or shaft includes gripping jaws which are held in position by a cam that engages and pivots the arms into a desired gripping position. The apparatus further includes a central or axial shaft which may be rotated to drive a specially formed cup against the exposed wiper blade mounting shaft to thereby cause the jaws to move in a manner which will effect axial movement of the jaws and pulling of the wiper arm assembly from the mounting shaft or stud.
