Bubbler a trademarked name that refers to a drinking fountain. The Bubbler was developed in 1888 by the then-small Kohler Company in Kohler, Wisconsin, which was already well-known for its faucet production. While Harlan Huckleby is credited with the actual design, it was Kohler that patented it and trademarked the name.
The Bubbler concept took off and there were many copies. Since the name was trademarked, other companies named their fountains "The Gurgler" and "The Gusher". In the end, the generic term "drinking fountain" became the standard term used in American English for a device that shoots water into the air for purpose of drinking.
The bubbler term is still used in several regional dialects of the United States such as in Wisconsin (mostly in the southeast part of the state, centered on Milwaukee, where it is considered part of the local dialect; residents of southeastern Wisconsin often state that the term is used within a "five county radius," however, the term's use has spread throughout the region, beyond five counties in the area.
Some people only call ones that are outdoors "bubbler" and some vice versa. Some residents of Milwaukee refer to them as "water bubbler". Most residents of southern Wisconsin refer to water fountains, both indoor and outdoor, as "bubbler".
