ARTHUR JOHN GOULSTONE, of No. 119, Tottenham Road, Southgate Road, in
the County of Middlesex, Land Agent. "AN IMPROVED SYSTEM OF AND METHOD
FOR VENTILATING RAILWAY AND OTHER TUNNELS, COLLIERIES, AND
MINES AND SHAFTS, FOR THE PURPOSE OF EXHAUSTING AND INSTANTANEOUSLY
DESTROYING THE FOUL AIR AND OTHER GASES THEREIN CONTAINED."
OTHER
This Invention consists in constructing a shaft through the arch of the tunnel
and inserting therein a wrot or cast iron pipe or tube varying in length from
4 to 20 feet or upwards, of the dimension of 12 ins., or more if necessary, in
diar; the placing of a gas pipe of small size at the bottom of the aforesaid
pipe or tube from which a constant and continual flow of gas will ascend through
the aforesaid pipe or tube, amalgamating with the noxious gases passing through a
perforated copper or other metal gauze, or asbestos or other suitable material, into a
funnel or other shaped receptacle, from which it will pass through a coiled cone or
other suitable means of transit, above which will be placed two small gas jets or
burners continually alight, thus setting fire to and consuming the foul air and
gases burning the same and rendering them utterly non-deleterious to health. The
whole of the upper part of the apparatus to be covered in and hidden from view
by a shield of cast iron or other metal in an ornamental style; also the construction
of a funnel shaped zinc or tin collector at the bottom of the aforesaid pipe or
tube to facilitate the draft from the tunnel through the pipe or tube before
mentioned; likewise the placing of a wrought or cast iron, or copper or other metal
pipe along and immediately underneath the arch of the tunnel of such dia., and of
such a length as may be necessary to convey the foul air and gases to the aforesaid
pipe or tube.
The Invention further consists of boring a hole of the necessary dia. at a desired
distance from the shaft of the colliery or mine, and inserting therein where required
wro't or cast iron pipes or tubes for the purpose of conveying the carburetted
hydrogen and other gases from the mine through the aforesaid hole or boring to a
receiver, placed at an elevation above the surface of the ground level at the top of
the mine, which gases will be burned and consumed after passing through a fine gauze
made of copper or other metal, wire, or asbestos or other suitable material; continual

kept continually alight, automatically or otherwise; and in addition a funnel shaped
receiver is placed at the bottom of the said tubing to collect and assist the escape of
the gases; and further, where any "blower" should be struck, that the gas should be
conveyed through tanned or other improved light piping, having at its end a funnel
shaped nozzle which would be applied to the "blower," and thus be conveyed to
the pipe immediately under the boring so as to prevent the dissemination of the gas
through the mine.
