IMPROVEMENTS IN GAS BURNER REGULATORS
Year: 1878

page_text: LETTERS PATENT to Gilderdale John Parkinson, of 307, Moseley Road, Balsall
Heath, near Birmingham, in the County of Worcester, for the Invention of
." IMPROVEMENTS IN GAS BURNER REGULATORS."
Sealed the 14th March 1879, and dated the 16th September 1878.
PROVISIONAL SPECIFICATION left by the said Gilderdale John Parkinson
at the Office of the Commissioners of Patents on the 16th September 1878.
GILDERDALE JOHN PARKINSON, of 307, Moseley Road, Balsall Heath, near.
Birmingham, in the County of Worcester. "IMPROVEMENTS IN GAS BURNER
REGULATORS."
This Invention has for its object the production of gas burner regulators in
which simplicity of construction with efficiency of regulation are combined..
The Invention consists in making in two pieces a shell or case, the lower part of
which is screwed to connect it with the gas supply, and the upper part is screwed
or otherwise fitted to receive a burner. In the lower part there is a fixed disc or
seat with a small hole in the centre. Between the upper and lower parts there is a
movable disc of such a size as to permit'a sufficient quantity of gas to pass between
its edge and the shell to supply the burner.
The movable disc has attached to its
under part a conical stem which serves as a valve when rising or falling through the
hole or seat in the fixed disc. When the gas enters the regulator it passes through
the hole in the fixed disc, and by its pressure raises the movable disc until the conical
stem or valve closes the hole in the valve seat below to such an extent as to admit
of only sufficient gas passing as is necessary to produce the requisite pressure at the
point of combustion. To prevent the possibility of the lights being put out by the
movable disc being suddenly forced up against the flange on the inside of the upper.
part of the case, notches are cut in the said flange to allow of a passage for the gas.
To adapt these regulators for giving different pressures at the point of combustion
it is necessary to vary the weights of the movable disc and cone to suit the conditions
they are required to produce.

GILDERDALE JOHN PARKINSON, of 307, Moseley Road, Balsall Heath, near
Birmingham, in the County of Worcester. * IMPROVEMENTS IN GAS BURNER
REGULATORS."
This Invention has for its object the production of gas burner regulators in which
simplicity of construction with efficiency of regulation are combined.
The Invention consists in making in two pieces a shell or case, the lower part of
which is screwed to connect it with the gas supply, and the upper part is screwed
or otherwise fitted to receive a burner. In the lower part there is a fixed disc or
seat with a small hole in the centre. Between the upper and lower parts there is a
movable disc of such a size as to permit a sufficient quantity of gas to pass between
its edge and the shell to supply the burner. The movable disc has attached to its
under part a long conical stem which serves as a valve when rising or falling through
the hole or seat in the fixed disc. When the gas enters the regulator it passes
through the hole in the fixed disc, and by its pressure raises the movable disc until
the long conical stem or valve closes the hole in the valve seat below to such an
extent as to admit of only sufficient gas passing as is necessary to produce the
requisite pressure at the point of combustion. To prevent the possibility of the
lights being put out by the movable disc being suddenly forced up against the flango
on the inside of the upper part of the case, notches are cut in the said flange to
allow of a passage for the gas.
In order that the foregoing may be more easily understood, Drawings are attached
hereto, of which the following is a description :-Fig. 1 is an clevation of the gas burner
regulator drawn to the natural size, which, however, may be varied to suit the size
or quantity consumed by each burner. Fig. 2 is a sectional elevation, drawn to a
much larger scale for the sake of clearness, and in which A is the lower part of the
shell or case, and B the upper part. C is the fixed disc with a hole or valve seat in
its centre, and D is the movable disc with its long conical stem or valve E depending
from it and working through the hole or valve seat in C; F, F, are notches or
“permanent leaks" cut in the bottom edge of the upper part so that should the movable
disc by a very sudden increase of pressure be driven up to the lower edge of the
upper part, the gas at the burner would not be extinguished, as sufficient would
flow through these notches to maintain the gas light; G is the burner, which of course
may be varied in form. Fig. 2 is a sectional elevation, and is almost identical with
Fig. 1; except that in this arrangement the moveable disc has a hole or "permanent
leak in it at H in lieu of the notches shown in the other Figure. No claim is,
however, made to the construction of a movable disc with a hole in it. It is necessary
to observe that the size of the valve and that of the hole or seat through which it
works should be such that under no circumstances should the valve be gas-tight,
but should always be capable of passing sufficient gas to keep the burner alight.
To adapt these regulators for giving different pressures at the point of combustion,
it is necessary to vary the weights of the moveable disc and cone to suit the conditions
they are required to produce.
Having now described and particularly set forth the nature of this Invention,
and the manner in which the same is or may be used or carried into effect, I would
observe in conclusion that I do not confine or restrict myself to the precise details
or arrangements I have described or referred to, as variations may be made there-
from without deviating from the principles or main features of this Invention, but
what I consider to be novel and original, and therefore claim as the Invention
secured to me by the herein-before in part recited Letters Patent is,―The construction

page_text: of a gas burner regulator with a fixed disc C through which a long conical stem or
valve E attached to a movable disc D rises or falls in the manner as herein described,
and shown on the Drawings.
In witness whereof, I, the said Gilderdale John Parkinson, have hereunto set
my hand and seal, this Thirteenth day of March, in the year of our Lord
One thousand eight hundred and seventy-nine.
