Improvements in and connected with Gas Pressure Gauges.
We, RICHARD THOMAS GLOVER, and JOHN GEORGE GLOVER, of the Firm Thomas
Glover & Co., Ld. 214 to 222 St. John Street, Clerkenwell, London, Gas Meter
Manufacturers, do hereby declare the nature of this invention to be as follows:-
This invention relates to that form of gas pressure Gauge in which the varying
height of water or other suitable liquid in a transparent or tube column is the means
by which the gas pressure is made apparent to the eye, and the object of this present
invention is to construct a pressure Gauge in a more economical manner and of more
convenient form and materials than has hitherto been the case, moreover the readings
are more apparent by reason of the greater bulk of water employed.
In carrying the invention into practice, a base is formed of preferably sheet metal
with two flanged orifices within which one end of two ordinary gas or lamp chimney
glasses or tubes are inserted upon the top of India Rubber, Leather, or other suitable
packing.
Bridge pieces are fixed across the beforementioned orifices, and into one of them is
screwed a solid rod (preferably), and in the other a tube is screwed and projects into
the base for connection to an inlet pipe from the outside, and to which the gas pipe
is attached by hose coupling or other means when desired.
The opposite ends of the beforementioned tube and solid rods stand slightly beyond
the tops of the lamp glasses and are screwed to receive nuts that serve to clamp-
capsule tightly upon the top end of the two glasses, one of which by the insertion of
an India Rubber or other suitable washer or packing is thereby hermetically sealed,
while the other is open to the atmosphere either through a hole in the capsule, or in
the solid rod, and may serve for filling purposes if desired.
The screwed tube and solid rod therefore rise centrally upon the two parallely
arranged glasses and by means of the nuts secure them in a water tight manner
to the base which is open to both glasses by the orifices beforementioned, but the
gas as it enters the inlet pipe is caused to rise up the central tube (which is closed
at its top end) and overflow through holes in the tube into the hermetically sealed
glass above the water, thereby exerting pressure upon said water and causing it to
proportionately rise in the other tube, when the pressure can be read off by a scale
fixed between the two glasses.
By this construction, it follows that all heavy brass connections are dispensed with,
and if a glass should break it is only necessary to insert a new one and screw the capsule
tightly upon it by the nut.

We, RICHARD THOMAS GLOVER and JOHN GEORGE GLOVER, of the Firm Thomas
Glover & Co. Id. 214 to 222 St. John Street, Clerkenwell, London, Gas Meter
Manufacturers, 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 that form of gas pressure Gauge in which the varying
height of water or other suitable liquid in a transparent tube or column is the means
by which the gas pressure is made apparent to the eye, and the object of this present
invention is to construct a pressure Gauge in a more economical manner and of more
convenient form and materials than has hitherto been the case, moreover the readings
are more apparent by reason of the greater bulk of water employed.
Our invention will be well understood by reference to the annexed drawing which
shows a sectional elevation of our improved gas pressure Gauge, the main feature being
the employment of two ordinary gas burner or Lamp chimney glasses in communi-
cation by a pipe for the free flow of water and the indication of gas pressure upon a
scale of such dimensions that the pressure can be more readily seen than by the
present gauge glasses and index besides which, the appliances or standard in which
the glasses are fitted, are less costly and more efficient for pressure testing purposes
than heretofore.
A, is a base or standard formed of preferably sheet metal with two flanged orifices
or recesses B, B, within which one end of two ordinary gas or lamp chimney
glasses C, C, are inserted upon the top of India Rubber, Leather, or other suitable
packing D.
E, is a connecting pipe, or it may be a bridge between for connecting the recesses,
in one of which is screwed a solid rod F (preferably), and in the other a tube G, this
being in connection to an inlet pipe H from the outside, and to which an ordinary
gas pipe or a flexible pipe by coupling or other means when desired can be affixed.
The opposite ends of the beforementioned rod F and tube G stand slightly beyond
the tops of the lamp glasses C, C, and are screwed to receive nuts I, I, that serve to
clamp a capsule J tightly upon the top end of the two glasses C, C, one of which by
the insertion of an India Rubber or other suitable washer K or packing is thereby
hermetically sealed, while the other is open to the atmosphere either through a hole L
in the capsule, or it may be in the solid rod, if so desired, and may serve for filling
purposes, if desired.
The screwed rod F and tube G are fitted centrally up the two parallely arranged
glasses C, C', and by means of the nuts I, I, secure them in a water tight manner to
the base A which is open to both glasses by the orifices beforementioned. The gas
as it enters by the inlet pipe H is caused to rise up the central tube G (which is closed
at its top end) and overflow through holes M in the tube G into the hermetically
sealed glass C above the water, thereby exerting pressure upon said water and causing
it to proportionately rise in the other tube C when the pressure can be read off the
scale N fixed between the two glasses C, C¹.
By this construction, it follows that all heavy brass connections are dispensed with,
and if a glass should break it is only necessary to remove a nut I and the capsule j
to insert a new one and screw the capsule tightly upon it by the nut.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we
claim is
The hereinbefore described construction of gas pressure gauge, consisting of two

base A, as and in the manner shown.
