Claim:
A liquid dispensing faucet comprising: a body comprising an inlet, an outlet, a liquid flow passage that extends from said inlet to said outlet, a valve chamber in communication with said liquid flow passage between said inlet and said outlet, a valve seat located in said valve chamber, and an access opening that provides access to said valve chamber from outside said body; a bonnet secured to said body in covering relation with said access opening, said bonnet comprising a catch; a valve element located in said valve chamber, said valve element adapted to be selectively engaged with and disengaged from said valve seat for controlling flow of liquid from said inlet to said outlet through said valve chamber; a valve stem that extends through said bonnet, said valve stem comprising an inner end secured to said valve element and an outer end located external to said body; a handle comprising a base and an upper portion connected to said base, said base of said handle pivotally secured to said outer end of said valve stem and said handle pivotable in a first direction from a first position to a second position, wherein said valve element is engaged with said valve seat and blocks liquid flow from said inlet to said outlet when said handle is located in its first position and said valve element is disengaged from said valve seat and allows liquid flow from said inlet to said outlet when said handle is located in its second position; said handle further comprising a safety lock that selectively prevents movement of said handle from its first position to its second position, said safety lock comprising: a latch that that is manually movable between a latched position and an unlatched position, said latch adapted to engage said catch of said bonnet and prevent movement of said handle from its first position to its second position when said latch is in its latched position, and said latch disengaged from said catch of said bonnet when said latch is in its unlatched position, a latch spring that biases said latch toward its latched position; a primary lock element that moves between a locked position and an unlocked position, wherein said primary lock element prevents movement of said latch from its latched position to its unlatched position when said primary lock element is in its locked position, and wherein said primary lock element allows movement of said latch from its latched position to its unlatched position when said primary lock element is in its unlocked position.
