ENOCH, Circuit Judge.
Plaintiff, Hugh W. Shumaker, brought this action against defendant, Gem Manufacturing Co., charging infringement of plaintiff’s patent No. 2,933,344, granted April 19, 1960.
The patent is directed to a pair of wind deflectors attached to the rear corner posts of a station wagon to break up the vacuum formed during forward movement of the vehicle. The vacuum created at the blunt end during forward movement of a station wagon draws road dust, dirt, grime, snow and other foreign material onto the rear window, obscuring rear vision and creating a driving hazard.
