Water glass filler

A water glass filler comprising:

• a body, said body having an inlet duct for water and a discharge duct for water;
• a flow valve, said flow valve being intermediate said inlet and outlet ducts for water, a closed condition of said flow valve preventing flow from said inlet to said outlet duct, an open condition of said valve permitting flow from said inlet to said outlet duct;
• movable means displacable in a first direction for opening said flow valve in response to an external force applied thereto in said first direction, and displacable in a second direction for closing said flow valve in response to the removal of said external force, whereby flow on demand is provided;
• first bias means biasing said movable means in said second direction to normally close said flow means upon removal of said external force;
• latching means displacable between a first unlatched position and a second position at which it is engaged by said movable means after said external force is removed while said valve is open for preventing said closing of said flow valve, whereby continuous flow is provided;
• and
• second bias means for biasing said latching means toward its first position so that upon the reapplication of said external force in said first direction to said movable means to disengage said latching means from said movable means, displacement of said latching means to its first position in response to said second bias means is permitted to free said movable means for displacement in its second direction in response to said first bias means whereby a flow-on demand mode of operation is initiated, and a continuous-flow mode of operation is terminated by similar force applications.
