ABSTRACT:
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.
