page_text: LETTERS PATENT to Samuel Newman Rodier, of Prospect Cottage, Strand-
on-the-Green, Chiswick, in the County of Middlesex, for the Invention
of "IMPROVEMENTS IN THE REGULATION OF GAS TO BURNERS, WHICH I CALL
"RODIER'S REGULATING GAS VALVE." "
Sealed the 16th March 1860, and dated the 17th September 1859.
PROVISIONAL SPECIFICATION left by the said Samuel Newman' Rodier at
the Office of the Commissioners of Patents, with his Petition, on the
17th September 1859.
I, SAMUEL NEWMAN RODIER, of Prospect Cottage, Strand-on-the-Green,"
Chiswick, in the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE REGULATION OF GAS TO BURNERS, WHICH I
CALL RODIER'S REGULATING GAS VALVE,' " to be as follows:
This Invention (which differs from my Invention patented August 26th,
1858, No. 1935, in the following particulars) consists, 1stly, I now use a
supply pipe of cylindrical form or tapering upwards, on the outer side of which
and near its termination I fix a collar or ring notched or having points on
its upper edge, a light loose cap rests on 'this ring or collar; this cap is so
constructed that as the pressure of gas passing through the supply pipe increases
the cap is lifted, and the top edge of its bottom rim brought nearer to the*
lower-edge of the ring or collar, thereby lessening the aperture through which
the gas passes on its way to the burner. 2ndly, I form at the base of supply
pipe a guide or holder, on which an outer regulating cap of larger dimensions
slides or screws; this outer cap covers the supply pipe and the rising & falling
cap, & regulates the height to which the latter can be raised by the action of
the gas, so that the aperture between the ring on supply pipe and the bottom of
the rising cap cannot be entirely closed. To the inside top part of the outer:

page_text: regulating cap I sometimes fix a pad or washer of felt or other soft fibrous
material, which acts as a buffer against which the top of the inner rising cap is
pressed by the gas. The gas passes through the outer cap by orifices made in
its lower part, and by causing the gas to pass from under the lifting cap in a
downward direction through these orifices to the burner, combined with the
formation of parts here set forth, the impetus of the upward action of the gas
against the lifting cap is broken, and the cap readily descends as the pressure
of the gas against it decreases. This valve, constructed as herein described, is
enclosed in an outer metal case or chamber of suitable construction and
dimensions, screwed at the lower end to admit of its being attached to ordinary
gas pipe, and at the top to hold burner.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Newman Rodier in the Great Seal Patent Office
on the 17th March 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
NEWMAN RODIER, of Prospect Cottage, Strand-on-the-Green, in the Parish of
Chiswick, County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of September, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Samuel Newman Rodier, Her special licence that I, the said Samuel
Newman Rodier, my executors, administrators, and assigns, or such others as I,
the said Samuel Newman Rodier, 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
"IMPROVEMENTS IN THE REGULATION OF GAS TO BURNERS, WHICH I CALL 'RODIER'S
REGULATING GAS VALVE,'" upon the condition (amongst others) that I, the
said Samuel Newman Rodier, my executors or administrators, by an instru-
ment 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.

This Invention (which differs from my Invention patented 26th August
1858, No. 1935, in the following particulars) consists, 1stly, I now use a

that as the pressure of gas passing through the supply pipe increases the cap
is lifted, and the top edge of its bottom rim brought nearer to the lower edge

passes on its way to the burner. 2ndly, I form at the base of supply pipe a

cap I sometimes fix a pad or washer of felt or other soft fibrous material
which acts as a buffer, against which the top of inner rising cap is pressed by the
gas. The gas passes through the outer cap by orrifices made in its lower part,

or chamber of suitable construction and dimensions, screwed at the lower end
to attach to ordinary gas pipe, and at the top to hold burner.
Having thus stated the nature of my Invention, I will proceed more fully to
describe the manner of performing the same.
DESCRIPTION OF DRAWING.
The Drawing is a section (about four times the size required for a single
burner) of a valve constructed according to my Invention. A, A, B, B,
represent the outer hollow metal case which is screwed at F, F, to receive
burner at the outlet at C, C, to connect to ordinary gas tube, and at E, E, to
receive holder for glass shade, and to connect its top and bottom parts together.
The advantage of fixing glass holder at the junction of these parts is, to allow
the flame to be in the centre of glass globes, and the holder is more securely held

page_text: than by the usual mode of attaching it to the top or bottom of burner by a
small screw. D; D, is a tube made of non-corrosive metal, glass, or other
suitable material fixed in lower part of outer case, forming a supply pipe,
through which the gas passes, having its base screwed or otherwise to receive
the outer regulating cap J, its outer surface being fluted or irregular, and to
its upper edge is attached a collar G projecting over its outer sides; H is an
inverted cup made of thin metal,, having its lower edge turned inward, and
connected with guide K; when the cap H rests on the collar G, or the bottom
of guide K on the projecting part of the supply pipe D, the gas passes through
the apertures of the collar G and below the guide K, between the flutes of
supply pipe, and through the orifices of the regulating cap J, and thence to the
burners, and as the pressure of the gas increases, the cap, together with the
guide, is lifted towards the collar G, thereby decreasing the space between
the collar and the bottom projecting edge of cap. To prevent the cap rising too
suddenly, a loose pipe with outer rim L or a ring. M is placed between the
supply pipe and guide K, which is lifted by the upper motion of the cap, and:
a pad of felt is attached to inside of top of outer cap, which can be regulated
to prevent the entire closing of the aperture between the lower edge of
inverted cap and the collar on supply pipe. Where the valves are required to
act in a horizontal position, I use a small spring under the top of regulating
cap... The sizes of these valves vary according to the required consumption
of gas.
Having thus described the nature of my Invention, and the manner of
performing the same, I wish it to be understood that I do not limit myself to
the precise details, but I claim the constructing and combining of a gas valve
as herein described by the use of a rising and falling inverted cup, arranged so
that the higher it is lifted by the pressure of gas its lower edge comes nearer
and nearer to a collar or ring attached to or formed on and projecting over the
outside of supply pipe, together or without any one or more of the other parts
herein named, and also attaching a holder for glass, or other shade at the
junction of the parts of outer case as herein described.
In witness whereof, I, the said Samuel Newman Rodier, have hereunto
set my hand and seal, this Sixteenth day of March, in the year of
"our Lord One thousand eight hundred and sixty...
