Editing Gong (section)

== Signal gongs ==
Gongs are also used as signal devices in a number of applications.

=== Boxing (sport) ===
A bowl-shaped, center mounted, electrically controlled gong is standard equipment in a [[boxing ring]]. Commonly referred to as ''the gong'', it is struck with a hammer to signal the start and end of each round.

=== Dinner gong ===

During the Victorian and Edwardian eras, it was often the custom in hotels, on ships, and in large, upper-class houses to sound a ''dinner gong'' to announce a meal was about to be served.<ref name="Iengar2002">{{cite book|author=Haravu Venkatanarasingha Verada Raj Iengar|title=Snapshots of History: Through the Writings of H.V.R.

=== Rail crossing ===
A [[railroad crossing]] with a flashing [[traffic signal]] or [[wigwag (railroad)|wigwag]] will also typically have a warning bell. Mechanical bells, known in some places as a gong, are struck by an electric-powered hammer to audibly warn motorists and pedestrians of an oncoming train. Many railroad crossing gongs are now being replaced by electronic devices with no moving parts.

=== Railcar mounted ===
Gongs are present on [[rail vehicle]]s, such as trams, [[streetcar]]s, trains, [[Cable car (railway)|cable cars]] or [[light rail]] trains, in the form of a bowl-shaped signal bell typically mounted on the front of the leading car. It was designed to be sounded to act as a warning in areas where [[Train whistle|whistles]] and [[Train horn|horns]] are prohibited, and the "''clang'' of the trolley" refers to this sound. Traditionally, the gong was operated by a foot pedal, but is nowadays controlled by a button mounted on the driving panel. Early trams had a smaller gong with a bell pull mounted by the rear door of these railcars. This was operated by the [[Conductor (transportation)|conductor]] to notify the [[Motorman (locomotive)|driver]] that it is safe to proceed.

=== Shipping ===
A vessel over {{convert|100|m|ft|-1|abbr=off}} in length must carry a gong in addition to a bell and whistle, the volume of which is defined in the [[International Regulations for Preventing Collisions at Sea]].<ref name=rule33>{{cite wikisource |title=International Regulations for Preventing Collisions at Sea |date=1972 |at=Rule 33}}</ref><ref name=AnnexIII>{{cite wikisource |title=International Regulations for Preventing Collisions at Sea |date=1972 |at=Annexe III}}</ref> A vessel at anchor or aground sounds the gong in the stern immediately after ringing a bell in her bows so as to indicate her length.<ref name=rule35>{{cite wikisource |title=International Regulations for Preventing Collisions at Sea |date=1972 |at=Rule 35}}</ref>

=== Theater ===
Electromechanical, electromagnetic or electronic devices producing the sound of gongs have been installed in theatres (particularly those in the [[Czech Republic]]) to gather the [[audience]] from the lounge to the auditorium before the show begins or proceeds after interlude.<ref>{{cite web|url=http://www.sfkpalantir.net/index.php?pid=175 |title=Palantir |publisher=Sfkpalantir.net |access-date=11 July 2013}}</ref><ref>{{cite web|url=http://webmagazin.cz/index.php?stype=all&id=148 |title=Webmagazín Rozhledna .::. nezávislý kulturně-společenský deník |publisher=Webmagazin.cz |date=29 October 2001 |access-date=11 July 2013}}</ref><ref>{{cite web|url=http://rn.rumburk.cz/index.php?id_rubrika=77&page=cislo |title=Město Rumburk – oficiální stránky města |publisher=Rn.rumburk.cz |date=6 January 2013 |access-date=11 July 2013}}</ref>

=== Vehicle mounted ===
In the Commonwealth, [[emergency vehicle]]s were fitted with electric, manual, or vacuum operated Winkworth bell gongs in the time before [[Horn (acoustic)|Martin's horns]] became available or [[Siren (alarm)|rotary sirens]] came into use
