page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine,
Lake, & Co., Patent Agents, Southampton Buildings, London, for
the Invention of" AN IMPROVED APPARATUS FOR MAINTAINING A CONSTANT
LEVEL OF WATER IN WET GAS METERS, AND FOR SEPARATING FROM VAPOUR
LIQUID HELD IN SUSPENSION IN THE SAME."-A communication from
abroad by Eugène Charles Maldant, of Paris, France, Civil
Engineer.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition, on
the 27th January 1874.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "AN IMPROVED APPARATUS FOR MAINTAINING
A CONSTANT LEVEL OF WATER IN WET GAS METERS, AND FOR SEPARATING FROM
VAPOUR LIQUID HELD IN SUSPENSION IN THE SAME," a communication, to be as
follows:-
:-

page_text: water of condensation, by means of the said improved apparatus, is
recovered and caused to return to the meters in such a manner as to
prevent or retard the sinking of the normal level of the water; conse-
quently the constancy and exactitude of their measurement will be
maintained, and at the same time the cost of their supervision and
repairing will be diminished.
The said Invention is illustrated in the accompanying Drawing.
Figure 1 is a vertical section, and Figure 2 a horizontal section of an
apparatus which is placed at the delivery aperture of the meter or of a
stcam or vapour generator; it is composed either of a number of
partitions perforated with holes for causing the circulation and division
of the gas or vapour, or of a number of concentric casings for effecting
the same purpose.
The gas or vapour will be caused to give up mechanically the liquids
held by it in suspension; these liquids ooze from the partitions through-
out their length, and return into the interior of the meter or generator,
or are recovered separately.
It will be readily understood that the dimensions of this apparatus will
vary according to the dimensions of the meter or of the generator to
which it is applied. The form of the said apparatus may also be varied,
and it may be constructed of any suitable material.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent
Office on the 24th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM 2
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of January, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty- 3
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Robert Lake, Her special licence
that I, the said William Robert Lake, my executors, administrators, and
assigns, or such others as I, the said William Robert Lake, my

page_text: 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 Invention
for "AN IMPROVED APPARATUS FOR MAINTAINING A CONSTANT LEVEL OF WATER
IN WET GAS METERS, AND FOR SEPARATING FROM VAPOUR LIQUID HELD IN
SUSPENSION IN THE SAME," communicated to me from abroad by Eugène
Charles Maldant, of Paris, France, Civil Engineer, upon the condition,
amongst others, that I, the said William Robert Lake, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and 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 I, the said William Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the
samė is to be performed, to be particularly described and ascertained
in and by the following statement :-
The Invention relates to maintain a constant level of water in wet gas
meters by separating from vapour liquid held in suspension in the same
when the gas leaves the gas meter, and consists in forming the pipe
next to the outlet with two perforated concentric inner cylinders,
through which the gas flows. The water held in suspension in the gas
is retained on the walls of these cylinders, and falls down them into the
meter again.
The accompanying Drawing represents an improved outlet pipe con-
structed according to the Invention.
Instead of being perforated the cylinders may be formed like Venetian
blinds, with blades fixed at proper distances from one another, upon
which the water is arrested in order to fall down in the meter, as above
stated.
Having thus described the nature of the said Invention, and the
manner of carrying it into effect, I claim and wish to secure by the said
Letters Patent, an improved apparatus for maintaining a constant level

page_text: of water in wet gas meters, as above described and represented in the
accompanying Drawing.
In witness whereof, I, William Robert Lake, have hereunto set
my hand and seal, this 23 day of July, in the year of
our Lord One thousand eight hundred and seventy-four.
