This invention relates to diaphragm regulators or governors in which the gas
pressure is on both sides of the diaphragm, and the invention consists in certain
improvements in the construction of the regulator whereby better results will be
obtained than heretofore
In carrying out my invention, I cast or form the body of the governor with a
hollow cylindrical portion at its upper end, is usual, to form the gas chamber, and
on one side of this cylinder I cast or form a lump or block
From the outside of the
body and upwards through this lump, I hore a hole, the lower portion of which is
threaded to receive a screw plug
At right angles to this hole, and through the cylinder, 1 bore second hole to
meet the vertical hole, the two holes forming passage from the inside to the outside
of the cylinder, the size of said passage being enlarged or contracted by 1 screw plug
as and for the purpose described in the patent granted to me and David William
Sugg dated 24th March 1886, No 4146
The top of the cylinder is covered by a flexible diaphragm in the usual wiy

This
diaphragm I may form of one or more thicknesses of a miteriil known in commerce
as baudrouche," and which consists of the shin of a fish, in combination with leather,
the two being joined together by india rubber solution Or I may take sarsenet or
fine silk, and prepare it by treating it with a mixture of glucose sugar, glycerine,
and Marseilles soap
This last named preparation is extremely suitable in hot
countries, as it is unaffected by any reasonable heat to which it may he exposed
Diaphragins prepared by either of the above modes are unaffected by the immonia,
large proportions of which are contained in some gases used for illuminating purposes
Secured to this diaphragm in the usual way, is a vilve This valve is, however,
mide, in the present instance, of a long taper form, and with a conical base
My

page_text: object in thus forming the valve is to present is small surface as possible to the
action of the incoming gas
Hitherto the area of the conical valves, in this class of
governor, has been so large, that when working in high pressure districts, it has been
found that for every increase of pressure above 2 inches, there has been a corre-
sponding diminution in the consumption of gas
The diaphragm and cylinder are unclosed by a cap in the usual way, into which
the burner tip is inserted The diaphragm must be loaded, as usu il, to ensure the
opening of the valve, should the pressure of the gas not exceed a certain limit

page_text: Improvements in Gas Regulators or Governors
I WILLIAM THOMAS SUGG of Vincent Works, Regency Street in the City of
Westminster, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement
This invention relates to diaphragm regulators or governors in which the gas
pressure is on both sides of the diaphragm, and the invention consists in certain
improvements in the construction of the regulator, whereby better results will be
obtained than heretofore
In the accompanying drawing, Fig 1 is a sectional olevation of what is known as
a Christiania burner with my invention applied thereto, and Fig 2 is a plan view
with the cap and the diaphragm removed
A is the body of the governor, which I cast or form with a hollow cylindrical
portion A at its upper end, as usual, to form the gas chamber, and on one side of
this cylinder I cast or form a lump or block B From the outside of the body A, and
upwards through thus lump, I bore hole (), the lower portion of which is threaded
to receive a screw plug D The upper end of this plug is coned to form a valve,
which will close the passage C₁ from the gas chamber to the hole C
At right angles to this hole C, and through the wall of the cylinder A¹, I bore a
second hole C, to meet the vertical hole C, the two holes and passage 01 forming a
passage from the inside to the outside of the cylinder A¹ The size of the passage C¹
is enlarged or contracted by the screw plug valve as and for the purpose described
in the patent granted to me and David William Sugg dated 24th March 1886,
No 4146
The top of the cylinder is covered by a flexible diaphragm E in the usual way
This diaphragm El my form of one or more thicknesses of a material known in
commerce as "baudrouche,' and wluch consists of the skin of fish, in combination
with leather, the two being joined together by india rubber solution Or I may take
sarsenet or fine silk, and prepare it by treating it with a mixture of glucose sugar,
glycerine, and Marseilles soap This last named preparation is extremely suitable in
hot countries, as it is little affected by any heat to which it may be reasonably exposed
Diaphragms prepared by either of the above modes are unaffected by the ammonia,
large proportions of which are contained in some gases used for illuminating
purposes
Secured to this diaphragm in the usual way, is a valve F, which is made, in the
present instance, of a long taper form, and with a conical base, so as to present as
small surface as possible to the action of the incoming gas Hitherto, the area of
the conical valves, in this class of governor, has been so large, that when working in
high pressure districts, it has been found that for every increase of pressure above
2 inches, there has been corresponding diminution in the consumption of gas

page_text: The diaphragm E and cylinder A¹ are enclosed by a cap G in the usual way, into
which the burner tip H is inserted The diaphragm E must be loaded, as usual, to
ensure the opening of the valve, should the pressure of the gas not exceed a certain
limit
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim 18
-
1 In gas regulators in which the gas pressure is on both sides of the diaphragm,
constructing the body of the regulator as herein shown and described, and the
application thereto of a screw-down conical valve, whereby the passage for the gas
from one side of the diaphragm to the other, may be more or less throttled as
set forth
2 In the preparation of diaphragms for gas regulators, the combination of
baudrouche and leather cemented together with rubber solution as set forth
3 The combination with a flexible diaphragın, of a valve of the form shown and
described
