Abstract: A device is provided for restoring the cleaning properties of worn vehicle windshield wiper blades. A notch in the body of the hand-held device accepts the working edge of the windshield wiper blade. A sharp steel blade recessed in the notch is thus placed in transverse contact with the working edge of the windshield wiper blade. As the device is drawn along the length of the windshield wiper blade, wiper blade material is removed as needed to restore its original sharp cross-section and smoothness, and hence, its cleaning ability.

Abstract: The invention is directed to a motor-driven chain saw having a drive motor arranged in a housing. The drive motor drives a saw chain on a guide bar via a sprocket wheel. The guide bar extends forwardly in the longitudinal direction of the chain saw and has an elongated slot in its rearward end facing toward the housing. Stud bolts fixed on the housing extend through the elongated slot in a direction transverse to the longitudinal direction of the chain saw. The rearward end of the guide bar is clamped between the housing and a sprocket-wheel cover through which the stud bolts extend. A holding device separate from the sprocket-wheel cover is provided at the rearward end of the guide bar for holding the rearward end of the guide bar in its position on the housing when the sprocket-wheel cover is removed. This holding device reliably holds the guide bar for mounting the saw chain.
