ABSTRACT:
A locking system for beverage taps (10) is provided for use with conventional beverage faucets (12) such as those utilized to dispense kegged beer and the like. The system (10) incorporates an elongated valve stem (14) which protrudes from the proximal end (38) of the faucet body (12) and is provided with an axial end bore (66) having pin threads (68) therein. A lock subassembly (18) actuated by a key (20) attaches to the valve stem (14) by a threaded driver pin (118) which engages the pin threads (66). A case cylinder (80) encloses the engagement position and overlaps a portion of the faucet body (12) such that antirotation ears (113) prevent relative rotation and loosening of the engagement except when the key (20) is utilized. When tightened, the lock subassembly (18) forces the valve stem (14) into a closed position, preventing opening of the faucet and dispensing of beverages.
