Year: 1870

page_text: LETTERS PATENT to Victor Bablon, of No. 40, Rue du Roi de Sicile,
in the City of Paris, in the French Empire, for the Invention of
"AN IMPROVED APPARATUS FOR REGULATING THE PRESSURE OF GAS IN GAS
BURNERS."
PROVISIONAL SPECIFICATION left by the said Victor Bablon at the
Office of the Commissioners of Patents, with his Petition, on the
30th April 1870.
I, VICTOR BABLON, of No. 40, Rue du Roi de Sicile, in the City of
Paris, in the French Empire, do hereby declare the nature of the said
Invention of "AN IMPROVED APPARATUS FOR REGULATING THE PRESSURE OF
GAS IN GAS BUENERS," to be as follows:-
The apparatus above referred to is completely closed, and works
without the aid of liquid. It consists of a cylinder, in which a piston
moves without friction; this piston is formed of a fine light disc
+

page_text: pierced in the centre for the reception of a tube which slides in the
bottom of the apparatus. At the lower part of the tube, and soldered
to the bottom of the apparatus, a spindle also penetrates without friction.
The top of this tube is furnished with a stopper fitting closely therein;
this stopper is a small tube closed at the top and open below, and is
provided laterally with a small cleft or breach for allowing more or less
gas to pass, according as the stopper is more or less withdrawn from
the tube, which latter is provided with two side openings which put the
lower part of it in communication with the interior of the cylinder.
The regulator is closed by a screw cover pierced in the centre, the
bottom and lid are furnished with a screwed junction, admitting of
readily fixing the apparatus to a conduit pipe and screwing it below
the burner.
The whole apparatus is in copper and lined internally with a galvanic
deposit of tin or lead to protect it from the deposits produced by the
gas. The gas supplied by the conduit enters the tube and leaves it
above the bottom of the cylinder by the side openings to spread itself
beneath the piston, thence it passes between the edges of the piston and
the sides of the cylinder, and another part of it follows the tube and
escapes by the breach of the stopper, and reaching above the piston
passes through the lid and supplies the burner.
The tube may be replaced by a simple shaft, furnished at its sides with
grooves or notches admitting of the passage of the gas.
This apparatus is intended for a single burner, but by increasing its
dimensions it may be made to regulate a number.
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said Victor
Bablon in the Great Seal Patent Office on the 29th November
1870.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, VICTOR 3
BABLON, of No. 40, Rue du Roi do Sicilo, in the City of Paris, in the
French Empire, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of April, in the year of

page_text: our Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Victor Bablon, Her special licence that I, the
said Victor Bablon, my executors, administrators, and assigns, or such
3 others as I, the said Victor Bablon, my 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 REGULATING THE
PRESSURE OF GAS IN GAS BURNERS," upon the condition (amongst others)
that I, the said Victor Bablon, 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 seven
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Victor Bablon, do hereby declare
the nature of my said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings, that is to say :-
The apparatus above referred to is completely closed, and works
without the aid of liquid. It consists of a cylinder A, A, in which a
piston B, B, moves without friction. This piston is formed of a fine
light disc pierced in the centre for the reception of a tube c, c, which
slides in the bottom of the apparatus. At the lower part of the tubo c, c,
and soldered to the bottom of the apparatus a spindle n also penetrates
without friction; the top of this tube is furnished with a stopper H
fitting closely therein. This stopper is a small tube closed at the top
and open below, and is furnished laterally with a small cleft or breach
for allowing more or less gas to pass according as the stopper is more
or less withdrawn from the tube c, c, which latter is provided with two
side openings o, o, which put in communication the part a', a', with the
interior of the apparatus.
The regulator is closed by a screw cover D pierced in the centre; the
bottom and the cover are provided with screwed junctions admitting of

page_text: readily fixing the apparatus to a conduit pipe and screwing it on below
the burner.
The whole apparatus is in copper and lined internally with a galvanic
deposit of tin or lead to protect it from the action of the gas; or it may
be entirely constructed of tin, except the delicate parts, which are made
of harder metal and galvanized as described.
The accompanying Drawings represent a full sized regulator for a
single burner, being of small dimensions and wholly metallic admits of
its adjustment close to the burner so that heat is communicated to it,
which effectually prevents the deposit of napthaline, condensation being
prevented by the heat.
The functions of the apparatus are as follows:-The gas supplied by
the conduit arriving at a', a', enters the tube c, c, and leaves it above the
bottom of the cylinder by the openings o, o, and spreads itself beneath
the piston B, B; thence a part of it passes between the edges of the
piston B, B, and the sides of the cylinder A, A, and another part
following the tube c, c, finds escape by the breach of the stopper II, and
the gas having arrived above the piston B, B, passes through the lid and
supplies the burner. The tube c, c, may be replaced by a single shaft,
furnished at its sides with grooves or notches admitting of the passage of
the gas, the supply of which, as above mentioned, is regulated by with-
drawing more or less the stopper II; but should an unexpected increase
of pressure occur in the delivery pipe this increase escapes below the
piston, which is forthwith raised a little higher by it, and the tube c, c,
rising simultaneously, the result is that the part of the openings o, o,
beneath the bottom of the cylinder A, A, is reduced, consequently
diminishing the supply of gas, which diminution is always in proportion.
to the increase. A decrease of pressure in the delivery pipe therefor
has an opposite tendency.
One of the peculiarly characteristic features of this Invention is, that
if the burner is removed whilst in action to replace it by another more
powerful one the consumption is not increased, as whilst replacing a
burner an autoinatic diminution of pressure occurs below the piston B, B,
this pressure is dependent on two causes, the weight of the piston and
the pressure above it, which latter pressure diminishes whilst replacing
a burner; the result being that the piston presses less on the gas, and
consequently allows less to pass.

page_text: The apparatus herein described is intended to regulate a single burner,
but by augmenting its dimensions it may be made to regulate a number
of burners.
Finally, the object of the Invention is to entirely suppress any
variations of pressure arising from the conduit pipe. The features of
novelty consisting of the arrangement in the interior of a cylinder (closed
by a lid) of a piston or valve, of which the tube with side openings
slides on a shaft or spindle fixed at the bottom of the cylinder, and of
the employment of a stopper for regulating the admission of gas, and
placed above the preceeding tube.
What I claim therefor and desire to secure by Letters Patent is, the
construction of regulators for controling the pressure of gas from the
delivery pipe to the burner as illustrated by the accompanying
Drawings, and as expressed by the final clause of this Specification.
In witness whereof, I, the said Victor Bablon, have hereunto set my
hand and seal, this Nineteenth day of November, in the year of
our Lord One thousand eight hundred and seventy.
V. BABLON. (L.S.)
