Historical Examples of vent pipe
It is indispensable that every acetylene apparatus shall be fitted with a safety-valve, or more correctly speaking a vent-pipe.
Typical simple forms of vent-pipe suitable for acetylene apparatus are shown in Fig. 7.
Nevertheless this form of vent-pipe produces a gurgling noise, and would be better for a trumpet-shaped mouth.
So tall a vent-pipe, however, seriously raises the centre of gravity of the bell and may make it top-heavy.
No water enters the vent-pipe from the holder, and therefore no gurgling or irregular pressure is produced.
