ABSTRACT:
Devices and methods for preventing pull away or drive away incidents. The preferred devices can be retrofitted to critical gas pipes on fuel trucks or gas tanker trucks. A version of my device can be readily employed with conventional automobiles. Through my system a vehicle engine cannot start or continue to ram until a proper disconnection is made from a fueling or refueling source. The preferred protection device comprises a rigid, frame having a base portion connected to a gas pipe with spaced apart clamps. An elongated arm pivotally extending from the frame terminates in a blocking plate. The blocking plate can be user-deflected to either block access to the gas connection, or to expose it. When disposed in the blocking position, the arm activates a spark-proof ignition switch, which enables the ignition circuit in the vehicle being fueled or loaded. When the blocking plate is deflected away to expose the gas connection, ignition is interrupted or prevented by the switch and the vehicle's engine cannot start or continue to run. After disconnecting the hose properly, the ignition circuit is reestablished by the switch concurrently with the return of the blocking plate. I have adapted the concepts of my device for ordinary automobiles to prevent pull away incidents at gasoline stations.
