| Abstract: |
An improved drive system for a windshield wiper suited for use in a vehicle cab structure including a cab frame with at least one window movably mounted on the frame for movement between open and closed positions. A windshield wiper is mounted on the cab frame for wiping the window and a drive is provided for the wiper. A releasable drive connection is disposed between the drive and the wiper and the present invention contemplates the provision of a linkage having a component disposed in the path of movement of the window and another part connected to the releasable drive such that when the window is moved from a closed position to an open position, the drive connection is released so that the wiper cannot be operated with the window in an open position.
