A protective cover is provided for substantially enclosing and protecting a bubbler head of a drinking fountain or the like against contamination when water flow to the bubbler head is turned off. In one preferred form, when the water flow is turned on, the protective cover is hydraulically elevated or pops up to a raised position permitting substantially unimpeded projection of a water stream from the bubbler head for drinking, etc. In an alternative preferred form, the bubbler head is hydraulically elevated or pops to a raised position within a stationary protective cover when the water supply is turned on for substantially unimpeded projection of water stream from the bubbler head through an open flow port formed in the cover.

Covered bubbler head for a drinking fountain

Drinking fountain

A pushbutton valve assembly for regulating water flow from a water supply to a point of use such as a bubbler head of a drinking fountain. The valve assembly includes a valve body adapted for mounting onto a suitable housing panel or the like, and includes an internal valve cartridge for on-off control of water flow. A pushbutton is rotatably carried by an escutcheon ring mounted rotatably onto an exposed outboard end of the valve body, and this pushbutton is axially movable between depressed and non-depressed positions for on-off operation of the valve cartridge. The pushbutton and the escutcheon ring include respective pairs of axially open wrench ports which can be axially aligned upon appropriate pushbutton rotation to accommodate reception of a tool such as a spanner wrench for rotatably removing the escutcheon ring from the valve body, thereby exposing the valve cartridge for service or replacement.

An improved freezeproof or freeze resistant valve assembly is provided for use in an outdoor drinking fountain or the like. The fountain includes a main on-off valve for coupling an underground water supply conduit via a standpipe to a fountain head to dispense water. The freezeproof assembly comprises a sump chamber installed below the frost line and having a piston mounted therein for reciprocal movement between advanced and retracted positions. When the main valve is turned off, the piston retracts by gravity within the sump chamber and residual water remaining within the standpipe drains to the sump chamber at low pressure through a normally open control valve mounted on the piston. When the main valve is turned on, the control valve is closed by water pressure and the piston is advanced within the sump chamber to expel the water previously collected therein through a discharge conduit coupled to a main fountain drain.

An emergency eyewash unit is provided for installation on a counter top adjacent to a sink, and includes a pair of spray heads mounted on a common swing arm for movement between a stored position alongside the sink and an active position with the spray heads disposed over the sink. The swing arm is mounted to the counter top by a control valve assembly which opens as the swing arm is moved to the active position to connect the spray heads to a water supply. The eyewash unit includes an adjustable cam mechanism with a set screw which cooperates with a selected one of a pair of cam tracks formed on the control valve to define a limited range of swing arm travel between the stored and active positions, wherein the set screw is quickly and easily mounted within a selected on of a pair of threaded ports to accommodate mounting of the eyewash unit on the left or right sides of the sink.
