Year: 1870

page_text: LETTERS PATENT to George Huntriss, Colliery Manager, John
Swinburn, Engineer, and James Wilson, Colliery Viewer, all of
Barnsley, in the County of York, for the Invention of "IMPROVE-
MENTS IN MEANS OR APPARATUS FOR SUPPLYING MINES AND OTHER PLACES
WITH LIGHTING GAS."
Sealed the 16th December 1870, and dated the 10th August 1870.
PROVISIONAL SPECIFICATION left by the said George Huntriss, John
Swinburn, and James Wilson at the Office of the Commissioners of
Patents, with their Petition, on the 10th August 1870.
We, GEORGE HUNTRISS, Colliery Manager, JOHN SWINBURN, Engineer,
and JAMES WILSON, Colliery Viewer, all of Barnsley, in the County of
York, do hereby declare the nature of the said Invention for “IMPROVE-
MENTS IN MEANS OR APPARATUS FOR SUPPLYING MINES AND OTHER PLACES WITH
LIGHTING GAS," to be as follows:-
The object of our Invention is to supply mines and other places,
situated on much lower level than the gas holder with lighting gas in a
cheap and convenient manner. For this purpose we employ and adapt

page_text: the induced current produced by a steam jet for drawing the gas into
and forcing it down a pipe leading to such mine. When the com-
bined current of gas and steam has arrived at its destination at or near
the bottom of the pit it is led into a receiving vessel of convenient size
and shape, entering the same at the top; this receiver serves to separate
and condense the steam which collects as water at the bottom and flows
off by a syphon pipe. The gas goes off by a pipe from the top of the
receiver, and is distributed to the burners as required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Huntriss, John Swinburn, and James
Wilson in the Great Seal Patent Office on the 10th February
1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
HUNTRESS, Colliery Manager, JOHN SWINBURN, Engineer, and JAMES
WILSON, Colliery Viewer, all of Barnsley, in the County of York, send
greeting,
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of August, in the year
of our Lord One thousand eight hundred and seventy; in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said George Huntriss, John Swinburn, and James
Wilson, Her special licence that we, the said George Huntriss, John
Swinburn, and James Wilson, our executors, administrators, and assigns,
or such others as we, the said George Huntriss, John Swinburn, and
James Wilson, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN MEANS OR APPARATUS FOR SUPPLYING MINES AND
OTHER PLACES WITH LIGHTING GAS," upon the condition (amongst others)
that we, the said George Huntriss, John Swinburn, and James Wilson,
our executors or administrators, by an instrument in writing under our,
or one of our, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and

page_text: in what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said George Huntriss, John Swinburn,
and James Wilson, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference
being had to the accompanying Drawings and to the letters of reference
marked thereon, that is to say :-
The object of our Invention is to supply mines and other places.
situated on a much lower level than the gas holder with lighting gas in a
cheap and convenient manner. For this purpose we employ and adapt
the induced current produced by a steam jet for drawing the gas into and
forcing it down a pipe leading to such mine. When the combined
current of gas and steam has arrived at its destination at or near the
bottom of the pit it is led into a receiving vessel of convenient size. and
shape, entering the same at the top; this receiver serves to separate
and condense the steam which collects as water at the bottom and flows
off by a syphon pipe. The gas goes off by a pipe from the top of the
receiver, and is distributed to the burners as required.
The annexed Drawing illustrates our Invention as applied to mines.
Fig. 1, shewing the general arrangement, and Figs. 2, 3, 4, and 5
shewing details drawn on a larger scale. A is the gas holder, from which
the mine is supplied by means of the gas pipe B fitted with a stop
cock C or valve. Where the pipe B turns down in the shaft a steam
pipe D with a small nozzle is fitted centrally in it. By means of a
cock Ę or a valve the amount and pressure of the steam issuing from
the nozzle can be regulated to any required extent. By the well known
action of the steam jet the gas is drawn into and forced down the pipe B,
thus conveying the gas down to the bottom of the pit. At the bottom
of the shaft or at a convenient distance from it the apparatus for col-
lecting the condensed steam is placed. This apparatus consists of a
vessel of convenient size and height. At or near the top of the same
the combined stream of gas and condensed steam enters. The water here
separates from the gas and falls to the bottom of the vessel F. from
whence it may be drawn off by a syphon or overflow pipe G. The gas thus
freed of the water is led off at the top of the vessel F, and is distributed
to the burners in the various parts of the workings as required.

page_text: Fig. 2 is an elevation, and Fig. 3 a section, drawn on a larger scale of
that part of the gas pipe B which is fitted with the steam jet pipe D
with nozzle. Fig. 4 is an elevation, and Fig. 5 a section on a larger
scale of the condensed steam collector or separator F.
Our Invention may in a similar manner be applied to other localities
situated at a sensibly lower level than the gas
holder.
And having now particularly described and ascertained the nature of
this our Invention, we declare that we claim as our Invention the
application of a steam jet in combination with a water separating appa-
ratus, substantially as and for the purpose set forth.
In witness whereof, I, the said George Huntriss, for myself and on
behalf of the said John Swinburn and James Wilson, have
hereunto set my hand and seal, this Seventh day of February
in the year of our Lord One thousand eight hundred and
seventy-one.
