PROVISIONAL SPECIFICATION.
Improvements in and relating to Gas Regulators or Governors.
I, JAMES LOVE, of Linton Road, Barking, in the County of Essex, Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in gas regulators or governors and has for
its object to provide a more reliable and efficient gas-governor than those heretofore
used of the kind or class in which the regulation is effected through the medium of
a small gasometer or bell which floats upon mercury or other suitable fluid
contained in an annular chamber.
The gas-governors of this kind or class as hitherto constructed are unreliable for
the reason that, in some instances, the pressure of gas is sufficient to blow out or
displace, more or less, the mercury or other fluid and thus render the governor
inoperative or cause an escape of gas through the vent usually provided at the top
of the casing.
To obviate this defect I provide a flexible diaphragm or cover of skin, oiled-silk
or other suitable material, between the gas-chamber of the governor and the
gasometer or bell. This diaphragm or cover is fitted over and firmly secured to
the inner or gas chamber of the governor. By means of the said flexible diaphragm
or cover the entrance of the gas into the annular chamber for the mercury or other
fluid is prevented, whilst the gas ascending in the said inner chamber from the main
will impinge against the said diaphragm and thus raise the float to operate the
controlling valve as required. I prefer to use glycerine in place of mercury in the
said annular chamber.
Another feature of my said invention is the provision of an air-chamber or float-
chamber around the lower edge of the gasometer or bell for the purpose of
increasing the buoyancy of the same and to diminish the quantity of glycerine
or other fluid necessary for the safe and efficient working of the governor.
Heretofore it has been customary to leave the vent at the top of the casing of the
governor open, and in some instances great inconvenience has been occasioned by
the escape of the fluid, or a portion thereof, through the said vent, during the
transport of the gas-governor from one place to another. To obviate the liability
to such escape of the fluid, I provide a screw-plug which is fitted into a tapped
hole in the top of the casing of the governor. This screw-plug is so arranged that,
when the governor is to be conveyed from place to place, the said plug can be
screwed in far enough to close the vent-hole. When the governor is to be used,
the vent-hole can be again opened by turning the said screw-plug so as to withdraw
the same sufficiently to uncover or expose the said vent-hole.
In carrying my said invention into practice, I find it advantageous to attach the
aforesaid flexible diaphragm or cover to the valve rod or stem and to secure
the edge of the said diaphragm or cover to the outer surface of the gas-chamber by
means of cement or other adhesive material and then fit tightly over it a ring or
band of steel or other metal. The said diaphragm or cover may, however, be
secured in any other convenient manner.
Moreover I find it advantageous to make the aforesaid float on the gasometer or
bell annular, and of semi-circular or similar form in transverse section.
I prefer to make the head of the aforesaid screw-plug in the form of an inverted
cup so as to effectually prevent the entrance of dust into the casing of the governor.

Improvements in and relating to Gas Regulators or Governors.
I, JAMES LOVE, of Linton Road, Barking, in the County of Essex, 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:-
My invention relates to improvements in gas regulators or governors, and has
for its object to provide a more reliable and efficient gas-governor than those
heretofore used of the kind or class in which the regulation is effected through the
medium of a small gasometer or bell which floats upon mercury or other suitable
fluid contained in an annular chamber.
The gas-governors of this kind or class as hitherto constructed are unreliable for
the reason that, in some instances, the pressure of gas is sufficient to blow out or
displace more or less the mercury or other fluid, and thus render the governor
inoperative or cause an escape of the gas through the vent usually provided at the
top of the casing.
To obviate this defect, I provide as illustrated in the accompanying drawing by
a vertical section, a flexible diaphragm or cover d of skin, oiled-silk or other
suitable material between the gas-chamber of the governor and the gasometer or
bell. This diaphragm or cover d is fitted over and firmly secured to the inner or
gas-chamber of the governor by a wire k in an annular groove. By means of the
said flexible diaphragm or cover d, the entrance of the gas into the annular chamber.
for the mercury or other fluid is prevented, whilst the gas ascending in the said
inner chamber from the main as indicated by arrows will impinge against the said
diaphragm d and thus raise the float and bell e to operate the controlling-valve i
as required. I prefer to use glycerine, water or any other sealing Huid in place of
mercury in the said annular chamber h.
Another feature of my said invention is the provision of an air-chamber or float-
chamber around the lower edge of the gasometer or bell e, for the purpose of
increasing the buoyancy of the same, and to diminish the quantity of glycerine or
other fluid necessary for the safe and efficient working of the governor.
Heretofore it has been customary to leave the vent at the top of the casing of
the governor open, and in some instances great inconvenience has been occasioned
by the escape of the fluid or a portion thereof through the said vent, during the
transport of the gas-governor from one place to another. To obviate the liability
to such escape of the fluid, I provide a screw-plug a which is fitted into a tapped
hole in the top of the casing or cover m of the governor. This screw-plug is
so arranged that, when the governor is to be conveyed from place to place, the said
plug can be screwed in far enough to close the vent-hole.
When the governor is
to be used, the vent hole can be again opened by turning the said screw-plug so
as to withdraw the same sufficiently to uncover or expose the said vent-hole. A
vent-hole b is provided in the screw-plug a.
In carrying my said invention into practice, I find it advantageous to attach the
aforesaid flexible diaphragm or cover d to the valve rod or stem g by a nut and
to secure the edge of the said diaphragm or cover to the outer surface of the gas-
chamber by means of cement or other adhesive material and then fit tightly over it
a metallic ring or band k.
The said diaphragm or cover may, however, be secured in any other convenient
manner.
Moreover I find it advantageous to make the aforesaid float f on the gasometer
or bell e annular and of semi-circular or similar form in transverse section.
At the base of the gas-chamber I fix an annular valve n, and at the top and
bottom of the said annular valve I provide a valve seating (or flat seating) in
order to receive the controlling valve of two inverted cups ii (or flat valves) these
J

page_text: said cups being ground in to the seatings jj. The cups i i are fixed at the end of
the valve rod g.
It will be understood that the shapes, materials and parts may be varied in many
ways within the scope of my invention.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a gas regulator or governor, the combination of the diaphragm d bell e
float annular chamber nut c valve rod g controlling valve ii (or flat valve) and
valve seatings jj (or flat seatings) with the valve n in a casing 1, substantially as
herein described and according to the accompanying drawing.
2. In a gas regulator or governor, the combination of the diaphragm d bell e
nut c valve rod g vent-hole and the screw-plug a with the controlling valve,
substantially as herein described and according to the accompanying drawing.
