Year: 1875

page_text: LETTERS PATENT to Victor Bablon, Manufacturer, of Paris, in the
Department of Scine, and Republic of France, for the Invention of
"IMPROVEMENTS IN APPARATUS FOR Regulating the FLOW OF LIGHTING Gas,
AS WELL AS FOR REGULATING THE DELIVERY OF LIQUID AND FLUID SUBSTANCES
OF ALL KINDS."
ealed the 21st September 1875, and dated the 2nd April 1875.
PROVISIONAL SPECIFICATION left by the said Victor Bablon at the
Office of the Commissioners of Patents, with his Petition, on the
2nd April 1875.
I, VICTOR BABLON, Manufacturer, of Paris, in the Department of
Seinc, and Republic of France, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR REGULATING THE FLOW OF
LIGHTING GAS, AS WELL AS FOR REGULATING THE DELIVERY OF LIQUID AND FLUID
SUBSTANCES OF ALL KINDS," to be as follows:-
This apparatus consists of a vertical cylinder provided with lids at the
top and bottom. These are both pierced to allow of free passage to the

page_text: gas; the top lid however is pierced laterally, leaving the centre solid.
Beneath the upper lid is a fixed division, in which a piston moves
without friction, and when in repose rests on the rim of the lower lid;
to this piston a hollow shaft is connected, and extends above it and
debouches just above the fixed division, through which it passes without
friction.
The object of this arrangement is as follows:-The gas coming from
the main beneath the piston surmounts it, flowing partly round its sides
and partly through the hollow shaft if not closed by a plug, with which
its lower part is provided. The gas having reached above the piston
enters the hollow shaft through sido openings made therein bencath the
fixed division, and escapes at the upper end of the shaft above the
division, and thence presents itself to the burner or burners fed by the
apparatus:
The piston is more or less raised according to the pressure of the gas
delivered from the main, which has the offect of raising the hollow shaft
towards or lowering it from the solid part of the upper lid, thus auto-
matically opening or closing the upper part of the hollow shaft, and so
regulating the delivery of gas to the burners.
The central or solid part of the upper lid is slightly hollowed so that
the hollow shaft in rising slightly engages therein in closing. This
renders the closing of the valve more gentle and progressive, and so
prevents the vibrations to which the valve would be subjected in closing
too abruptly.
The quantity of gas or fluid delivered by this apparatus depends on the
size of the orifice offered to it through the piston, as well as in the weight
of the whole movable part which the gas or fluid raises.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Victor Bablon in the Great Seal Patent Office on
the 29th September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, VICTOR
BABLON, Manufacturer, of Paris, in the Department of Scinc, and
Republic of France, send greeting.

Lettors Patent, bearing date the Second day of April, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
cighth 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 others as I, the said Victor Bablon, my executors, admini-
strators, 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 “IMPROVEMENTS IN APPARATUS
FOR REGULATING THE FLOW OF LIGHTING GAS, AS WELL AS FOR REGULATING THE
DELIVERY OF LIQUid and Fluid SubSTANCES OF ALL KINDS," upon the condition
(amongst others) that I, the said Victor Bablon, my executors or admi-
nistrators, by an instrument in writing under my, or thoir, or one of
their hands and scals, should particularly describe and ascertain the
naturo of the said Invention, and in what manner the same was to be
performed, and causo the same to be filed in the Great Scal Patent
Office within six 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 be performed, to be particularly described and ascertained in and
by the following statement and accompanying Drawings, that is to
say :-
· The regulator forming the subject of the present Invention combines
the advantages of the various apparatus now in use without any of their
imperfections. It is devoid of either membrane or liquid, is much
reduced in size, and acts with perfect precision.
In the accompanying Drawings the improved regulator is shown by
an external view, Fig. 1, and double the natural size; by Fig. 2 it is
shown in section; Figs. 3 to 6 inclusive are sections of the various parts
of which it is composed.
The apparatus consists of a straight cylinder 0 (closed by two lids A
and B), and in which the piston P moves. The cylinder O is screw
threaded top and bottom for receiving the screws of the lids.A and B,

page_text: and insido it is the division D, fixed or otherwise, and pierced with a
central aperture for the passage without friction of the shaft T of tho
•piston P.
The lower lid A, Fig. 4, open throughout, offers a free passage to the
gas, which thus arrives beneath the piston P. The sides of the lid A
which enter the cylinder C arc cut sloping, and serve as supports to the
piston P when there is no issue of gas.
The upper lid, Fig. 3, on which the burner is screwed, is also pierced
throughout by two orifices G, more or less out of the centre and reaching
above to the central opening Thus inside and between the two orifices
is a plain part, which is hollowed concentrically with the cylinder, giving
an inclination to the hollow V, whose object will be hereafter oxplained.
The piston P, Fig. 5, is very thin and cut square all round its circum-
ference, and here and there small projections arc-placed which centralize
the piston in relation with the cylinder C, whilst leaving the requisite
play between the piston and the inside of the cylinder The piston is
solid with the centre tube T, which forms its shaft, and is of a certain
length and moves vertically without friction, guided as it is in the
opening of the division D. The piston and tube being thus united, the
same movements are common to both.
The piston T is pierced with two or more openings I between tho
division D and the piston P, causing a communication between the
space existing between the division D and piston P with the interior of
the hollow shaft T. This shaft extends below the piston, and receives
the plug II, Fig. 6, the bottom of which is closed, and is open at the top
with two side openings j. By insorting the plug II more or less in the
shaft the size of the openings 3 is more or less increased or diminished,
and they can be completely closed if desired.
Action of the Regulator -The gas coming from the screw cap A
spreads itself under the piston P, and surmounts it by flowing partially
round its sides and partly through the interior of the tube T, if the lower
part of this shaft T has not been completely closed by the plug II.
Having reached above the piston the gas enters the shaft T through
the openings I, and escapes at the upper end of the shaft above the
division D, and thence directs itself to the burner or to the burners fed
by the apparatus.
