  • Hose coupling lock for a valve and method of use of the same
    Patent number: 6736367
    Abstract: A method and apparatus for locking a hose onto a hose coupling for a valve. A rigid linkage is pivotally mounted adjacent to the valve with a hose engaging member at a first end and an actuator engaging member at a second end. The linkage is pivoted to position the hose engaging member in the engaged position overlying and maintaining in engagement a hose with the hose coupling. A manual valve actuator of the valve is moved to a first position with the valve open. The actuator engaging member engages the manual valve actuator to prevent pivoting of the linkage and maintain the hose engaging member in the engaged position until the manual valve actuator has been returned to a second position with the valve closed.
