Year: 1884

page_text: I HYPPOLITE BESSON, Mechanical Engineer of 46 Bonner Road and I JOSEPH
HENRY BURROWS, Gas fitter of 44 Bishop Road, Bethnal Green, both in the
County of Middlesex, do hereby declare the nature of our said invention for
IMPROVEMENTS IN GAS GOVERNORS, to be as follows:-
The main objects of this invention is to construct a simple and reliable governor
to act directly on a supply cock, and also to regulate the flow of gas, from the main
or meter to the burners always in proportion to the numbers and powers of the
lights required to be used.
The Invention consists of an apparatus composed of an outside cylinder of a
convenient size, proportional to the meter or gas to be burned in lighting. Within
this cylinder is placed another cylinder or inverted cup, mouth downwards in
annular seal filled with mercury, glycerine, or any other suitable fluida. An inlet
and outlet pipe are fixed to the bottom of the cylinder and may project above
or under the mercury, glycerine or other suitable fluids underneath the inverted
cylinder.
In the center of the inverted cylinder is fixed a simple rod, which, passing
downwards through the apparatus is linked to a lever attached to the supply cock.
This lever has an arm on which a ball or weight can be adjusted so as to enlarge
or diminish the power of the lights without opening the apparatus.
Sometimes instead of the regulating ball or weights the rod traversing the
apparatus to the lever of the supply cock can project over the apparatus and small
round weights like washers are laid through on the rod until the proper lights
is obtained.
This apparatus can be made of glass, china or metal to suit the sealing liquid
used. The plug of the supply cock is set between two centers.
The mode of action of this apparatus is as follows:-The gas is admitted through
the inlet pipe to the inverted cylinder and goes to the burners by passing through
the supply pipe or outlet: with any extra pressure higher than the degrees adjusted
for at the regulating ball or on the rod the inverted cylinder or cop will rise and
carry with it the lever and turn off the cock in same proportion, or will full at
lower pressure and open the cock, and as every light turns off, a corresponding
quantity of gas will be shut at the cock and this will continue till the last light is
turned off when the cock then will be completely shut.

page_text: I, HYPPOLITE BESSON, mechanical Engineer of 46 Bonner Road and I JOSEPH
HENRY BURROWS gas titter of 44 Bishop Road Bethnal Green, both in the county
of Middlesex do hereby declare the nature of our invention for IMPROVEMENTS IN
GAS GOVERNORS OR REGULATORS, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
The main object of this Invention is to construct and fix a simple and reliable
governor to act directly on the cock, which supplies gas to the meter and regulates
the flow or pressure of gas before passing through the meter, in a same proportion
to the number and power of the lights required to be used.
The Invention Consists of an apparatus composed of an outside cylinder of a
covenient size proportional to the size of the meter or gas to be used; within this
cylinder is placed another cylinder or inverted cup, mouth downwards in a seal
such as mercury, glycerine or any such liquid, which will not freeze or evaporate
easily, and covers an inlet pipe coming from the meter and outlet pipe and going
to the burners, gas stoves or any such purposes; these said pipes are fixed to the
bottom of the outside cylinder, and passing through the seal, project above it
underneath the inverted cup, this said cup is connected to the main cock by a
small rod passing downwards through the center of the apparatus and is linked to
a lever fitted on the plug of the cock.
In order that our said Invention may be clearly understood, we shall now
proceed to describe the same more particularly and for that purpose we shall
refer to the several drawings on the annexed sheet, on which same letters of
reference will indicate corresponding or similar parts in all the drawings.
Fig. I, represents a vertical section of the governor. Fig, 2, an elevation of the
same. Fig, 3, represents a longitudinal section of the main cock, and Fig, 4, a plan
of the same. A, A, Fig I & 2 is the outside cylinder, B, B the inverted cup mouth
downwards in a seal g made of glycerine; an inlet pipe D and an outlet pipe D¹
are fixed through the bottom of the outside cylinder A, A, and are carried above
the seal g underneath the inverted cup B B; the inverted cup B B is connected
to the cock C by the rod R, linked to the lever L which is fitted on the plug P by its
arnis passing through the holes o, o, made at each end of the plug P, one arm
of the said lever is made longer so as to fit if necessary a ball or weight, which can
be adjusted to increase or diminish the flow or pressure of the gas, but we prefer to
increase or diminish the flow or pressure of the gas, by having the rod R which is
fixed to the top of the inverted cylinder project through the said cup to a suitable
length on which small weights V like washers can be fitted.
The sealing of the small rod R is obtained by having a small tube b soldered to
the bottom of the outside cylinder A, through which the rod R passes, and the said
tube is enclosed by a tube K K, fitted to the top of the cup, and hangs over the
tube b in the seal of glycerine and makes a gas joint.

page_text: The supply cock C is fixed on the main pipe E and supplies gas from the main
to the meter by pipe El connecting the meter not shown in the drawing: it has a
hollow plug P Fig. 3. on which is formed a spiral alott or opening 9 made on the
side to which the gas goes to the meter this said slott is made of same width through
all its length so as to open and shut nearly equal parts of its length for equal number
of lights turned on or turned off or for equal increase or decrease of the pressure in
the main; the plug P is adjusted and held at each end p p by center screws rr,
fitted on small brackets d d formed on the body of the cock C; the body of the
cock is provided with two oil cups H, H which keep the plug P well lubricated.
The lubricant used for this purpose is made of lard oil mixed with a small quantity
of paraffin.
The apparatus can be made of glass, china or metal so as to suit the sealing
liquid.
The mode of adjusting the buoyancy of the inverted cup B, B 80 as to be in
equilibrium at all times with the pressure or gas required to be burned is done as
follows:-The rod R connecting the cup B with the main cock is either raised
upwards to F or pressed downwards to F¹ until the desired light or the required
pressure is obtained then to keep the cup in this found position the said cup B is
balanced by adding or taking off the small weights or washers V placed on the top
of it. When the equilibrium of the inverted cylinder with the pressure of gas to
be consumed is made, the mode of action of the governor is thus:-The gas is
admitted through the cock C by pipe E, to the meter by pipe E', then from the
meter by the pipe D or inlet pipe to the governor underneath the inverted cup B
and taken to be consumed by the outlet pipe D¹ D¹; now, it is evident, if every
opening on the outlet pipe D¹, D¹ were turned off, the pressure left under the
inverted cup, not finding an outlet would rise the said cup and shut the cock or
nearly so, and the lever L would take the position F1, but, if one or more burners
are turned on and lighted, or the pressure in the main is diminished, the pressure
inside of the cup is also diminished in the same quantity, and the cup will fall and
open the cock to a distance equal to the gas taken to be consumed, or equal to
the pressure reduced in the main, and restore the formal pressure to the gas passing
through the governor to the outlet, and at every light turned on or for every
decrease of the pressure the cock will open to let a corresponding quantity of gas
pass equal to the pressure decreased, or to the lights turned on, and this will
continue until the position of the lever L takes the position F¹, when the cock C
will be fully open. On the contrary, if the burners are turned off or the main
pressure increased the extra pressure accumulating under the inverted cup will rise
it and shut the cock of a distance equal to the number of burners turned off or
equal to the extra pressure of gas in the main and restore, as said before, the formal
pressure and at every light turned off a corresponding quantity of gas will be shut
off at the cock C and this will continue till the last light is turned off, when the-
cock will be shut or nearly so.
By having the inverted cup made to act direct on the cock C, which supplies the
meter, a longer range of sensitiveness of rise and fall is obtained, for a five light
meter the inverted cup will have a rise and fall of nearly two inches, and for
100 light meter of five inches.
We are not aware that prior to the above specification a governor had ever been
made and applied to act the main cock automatically, which supplies gas to the
meter, and controls the gas pressure before entering the meter, and we would have
it understood that the forms and dimensions of the parts and their arrangements
with regard to one another may vary according to suit the position of the meter, main
pipe, and locality, without departing from the invention, therefore having thus set
forth the nature and objects of our invention what we claim as new and desire to
secure by letters patent is
1. For regulating gas; The employment of a governor to shut and open the
main cock automatically as substantially described as herein before described and
illustrated.

page_text: 2. The arrangement by which the main cock is acted automatically as
substantially described as herein before described and illustrated.
3. The use of the lever L, cock C with plug P, oil cup H H, & center screw
as substantially described as herein before described and illustrated.
