An Apparatus for Cleaning Water Gauge Taps or Cocks of Steam
Boilers when under Pressure or otherwise.
I, HENRY WATSON, Engineer, c/o Messrs. Menzies & Co., Ltd., Shipbuilders and
Engineers, Leith, N.B., do hereby declare the nature of this invention to be as
follows:-
The invention consists of a metal stuffing box into which is fitted a suitable drill
or other instrument to which a handle is applied for forcing the same into the
channel of gauge tap, or cock.
The apparatus is screwed to fit the opening usually made for cleaning purposes
and after being securely fitted into its position the tap or cock is opened full and
then the drill or other instrument is forced through the channel thereby removing
all obstructions, which operation may be done whilst the boiler is under full
pressure or otherwise, without allowing escape of steam, or water, thereby
preventing any chance of accidents through scalding.
