ABSTRACT:
Disclosed herein is a locking mechanism for closing the gas line in an automobile, said locking mechanism comprising a tumbler lock engaged to a rotary valve adapted for insertion into a fuel line. The valve itself comprises a rectangular body having a transverse circular opening formed therein across which the fuel flow communicates. Installed in the transverse opening is a rotary planar vane being rotatable to a first position uncovering the inlet and outlet ports of the circular opening and conformed on its exterior edges to the opening periphery, said vane having stand-offs on the bottom thereof for providing a communicating path for the gasoline and being rotatable to a second position closing off the communicating path. In the last position the thickness of the vane blocks the passage of gasoline thus precluding unauthorized use of the automobile. It is contemplated that the foregoing lock be installed in the floor surface of the automobile, the valve extending therefrom being placed into the fuel line.
