I JOHN DOUGILL Gas Engineer of 83 Choir Street Broughton Lane Manchester in
the County of Lancaster do hereby declare the nature of my invention for IMPROVE-
MENTS IN GAS REGULATORS to be as follows:-
In situations were a regular and constant stream of Gas is required or where the
supply of Gas for illuminating purposes fluctuates thereby causing the Lights to burn
unsteadily. I remedy the defective supply by the use of my Gas regulator-which
may be placed in comunication with the Gas service pipe in any convienient position
between the unsteady Lights and the cause of the fluctuations of the Gas for example
should the Illuminating Lights flicker in the vicinity of a Gas Engine at work or
where any other disturbing cause produces a fluctuation in the Gas supply I fix my
antifluctuator or Gas regulator between such cause and the Gas Lights which are
required to burn steady.
I construct my Gas regulator in the following manner.
Upon a Tube I place a number of Indianrubber Gas Bags prefferably close
together & fit the neck of each Bag to the tube sufficiently close to prevent the Gas
from escaping betwixt the neck of the Bag & the tube that portion of the tube within
the Bags is purforated or the tube may be cut into detached pieces if purforated it
must be done in such a manner that the Gas may flow freely into each of the Bags
placed upon it the area of the purforations to be equal to the diameter of the tube.
The diameter and length of the tube or tubes, and allso the capacity of the Bags
& number of Bags must be in acordance with the magnitude of the fluctuation to be
overcome that is the size of the Tubes must be the same as that of the main supply
pipe of the premises in which the Regulator is required-or the main Gas service pipe
between the desturbing cause and the Lights, Or the pipe may itself have the Rubber
Bags placed upon it in the manner before described. For example an half inch servise
pipe with three Bags placed thereon having each a cube capacity of about one quarter
However
foot of Gas will gennerally surfice to overcome the fluctuation of the Gas.
in cases of extreem fluctuation I add one or two extra Bags as the case may require.
The Tubes & Bags may be arranged in any form to suit the situation in which they
it may be required to be placed or to render the apparatus compact or portable.

page_text: JOHN DOUGLLL Gas Engineer 83 Choir Street Lower Broughton Manchester in the
County of Lancaster I 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 :-
In situations were a regular and constant stream of Gas is required or were the
supply of Gas for illuminating purposes fluctuates, thereby causing the Lights to burn
unsteadily, I remedy the defective supply by the use of my Gas Regulator, which may
be placed in communications with the gas service pipe, in any convienient position
betwixt the unsteady lights, and the cause of the fluctuation of the Gas. For example
should the illuminating lights fluctuate in the vicinity of a Gas Engine at work, or
were any other disturbing cause produces a fluctuation in the Gas supply, I fix my
Gas Regulator between such disturbing cause and the Gas Lights.
I construct my Gas Regulator in the following manner. Upon a Tube I place a
number of indiarubber Gas Bags, preferably close together, and fit the neck of each bag
to the Tube, sufficiently well to prevent the Gas, from escaping betwixt the necks of the
bags and the Tube, That portion of the Tube within the bags is perforated or it may be
cut into detached pieces, but when perforated the perforations, must be in such a manner
that the Gas passing through the Tube will flow freely into each of the bags placed
upon the Tube, In place of the bags Indiarubber Diaphrams may be used but I prefer
the bags, The diameter and length of the Tubes and allso the capacity and number of
the Indiarubber. bags must be in accordance with the magnitude of the fluctuation to
be overcome. That is the size of the Tubes must be the same as that of the main supply
pipe of the premises in which the Gas Regulator is required, Or the main Gas service
pipe betwixt the disturbing cause and the lights may itself, have the Indiarubber Bags
placed upon it. In the manner before described, For example a half inch service pipe
with three bags placed thereon having each a cubic capacity of about one quarter foot
of Gas, will generally suffice to overcome the fluctuation of the lights, However in
cases of extreme fluctuation in the lights I add to the service pipe, one or two additional
bags as the case may require.
The Tubes and the bags, may be arranged in any form suitable to the situation in
which the Regulator may be placed, that is in either one straight length, or hent in
any form necessary to make the Gas Regulator apparatus compact.
Having now described the nature of my Invention and the manner in which the
same is to be carried into effect, I now claim,
First. The application in combination of the Tubes and Indiarubber Bags as set
forth and for the purpose described.
Second. The application in combination of the Tubes and Indiarubber Diaphrams
in the place of Bags as set forth.
