Measuring Air, Gas, and other Fluids.
I, HOWARD LANE, of 115 Palmerston Buildings Old Broad Street in the City of
London, Engineer do hereby declare the nature of my said invention to be as
follows:-
The object of my invention is to manufacture improved apparatus for measuring
air, gas, and other fluids, and indicating the quantities measured.
My invention consists of a hollow vessel, preferably approximating to a spherical
form, and made in two parts, each part being provided with a flange, for convenience
in bolting the same together, and fitting a flexible diaphragm therein.
A valve box and valve (preferably of the piston type) are fitted, having passages to
each half of the vessel, and induction and eduction ports and connections from and to
other vessels, from which the fluid is drawn, or received under pressure or otherwise
and conveyed away.
The admission of the fluid is so arranged that the diaphragm is carried from one
part of the vessel to the other, and at each termination of its range of action a
difference of pressure arises between the induction and eduction fluid, which difference.
of pressure causes the valve to be reversed, thus rendering the flow continuous, and
the action automatic.
The valve is fitted with a rod, which passes through a stuffing box.
This rod is connected, in any convenient manner, with counting and recording
mechanism (electrical or otherwise) whereby the number of times that the vessel is
filled with fluid is recorded and registered.
The diaphragm is fitted with a small disc of leather, rubber, metal, or other suitable
material for closing the passages to the vessel, and preserving the diaphragm from
injury by being driven into the passages.
The disc may be utilized in reversing the valve by means of suitable connecting
gear.
The valve may also be worked by means of electricity, the connection being effected
by the contact of the disc with suitable terminals.

page_text: Improvements in the Method of and in Means and Appliances for
Measuring Air, Gas, and other Fluids.
I HOWARD LANE of 115 Palmerston Buildings, Old Broad Street in the City of
London, Engineer, do hereby declare the nature of my said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by the
following statement:-
The object of my invention is to manufacture improved apparatus for measuring
air, gas, and other fluids, and indicating the quantities measured.
My invention consists of a hollow vessel, preferably approximating to a spherical
form, and made-in-two parts, cach part being provided with a flange, for convenience
in bolting the same together and fitting a flexible diaphragm therein.
A valve box and valve (preferably of the piston type) are fitted having passages to
each half of the vessel, and induction and eduction ports and connections from and to
other vessels from which the fluid is drawn, or received under pressure or otherwise;
and conveyed-away.--
The admission of the fluid is so arranged that the diaphragm is carried from one
part of the vessel to the other, and at each termination of its range of action a
difference of pressure arises between the induction and eduction fluid, which. difference
of pressure causes the valve to be reversed, thus rendering the flow continuous, and
the action automatic.
The valve is fitted with a rod which passes through a stuffing box. This rod is
connected, in any convenient manner with counting and recording mechanisin
(electrical or otherwise) whereby the number of times that the vessel is filled with fluid
is recorded and registered.
The diaphragm is fitted with a small disc of leather, rubber, metal, or other suitable
material for closing the passages to the vessel, and preserving the diaphragm from
injury by being driven into the passages.
The disc may be utilised in reversing the valve by means of suitable connecting
gear.
The valve may also be worked by means of electricity, the connection boing effected
by the contact of the disc with suitable terminals.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a sectional elevation of the receiver. Fig. 2 is a plan of the same. Fig. 3
is a plan (on a larger scale) of one of the perforated plates c c. Fig. 4 is an enlarged
sectional elevation of the valve box and valve. Fig. 5 is a side view. Fig. 6 a plan,
and Fig. 7 a horizontal section of the valve box, on the line 1-2 of Fig. 4.
a is the receiver, consisting of two bowls, bolted together, and preferably formed as
shown in Fig. 1. a¹ is the upper half and a the lower half, the latter being provided
with a suitable stand a³ cast therewith. are the passages for the gas. c c are two
perforated plates (shown in plan also in Fig. 3) which prevent the diaphragm d
entering the passages. The outer edge of the diaphragm d is fixed between the

page_text: flanges of the bowls, and the diaphragm is provided at d¹ with a disc of leather, rubber'
metal or other suitable material, for closing the passages and preserving the diaphragm
from injury.
Referring to Figs. 4, 5, 6, and 7, e is the cylindrical valve box. f is the inlet
passage and ୨ is the outlet passage. ele are three annular ports in the valve box.
is the cylindrical valve. ii are ports formed in the valve. is the valve rod,
bolted to the central disc of the valve, as shown in Fig. 4. This rod passes through
the stuffing box formed in the cover. m is a rod screwed to the lower cover of the
valve box. This rod m acts a stop to limit the downward stroke of the valve. The
sleeve m' surrounding the rod k in like manner limits the upward stroke of the valve.
The rod k may be fitted to any suitable counting apparatus, electrical or otherwise,
as hereinbefore mentioned.
The diaphragm d is air proof, and is so formed that it can adjust itself exactly to the
contour of the inside surface of the bowls.
In the position of the valve shown in the drawings, the gas or other fluid to be
measured is entering by the passages fel and i to the inside of the valve h, and thence
to the upper part of the receiver a above the diaphragm. The fluid
below the diaphragm is passing out by the passages b'i and e² to the outlet passage g;
the passage being closed by the valve.
by the passage
.
When the diaphragm has descended to and is pressed closely to the lower bowl a
in every part, the sudden check which is given to the fluid passing into the meter,
causes an increase of pressure. This increase of pressure acts upon the solid central
disc of the valve h, thereby causing its downward stroke; closing the port e¹ and
opening the port e³, and thus admitting the fluid below the diaphragmn, and
opening the eduction to the fluid above the diaphragm. These operations are
repeated as long as the gas flows.
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 1
claim is:
1. The method of measuring air, gas, and other fluids, by means of a vessel a fitted
with a flexible diaphragm d in combination with a valve so formed and fitted as to
become automatically reversed by the increase of pressure caused by the check
imparted to the fluid when the receiver is filled, substantially as hereinbefore
described and illustrated by the drawings.
2. In combination with means and appliances for measuring air, gas, and other
fluids, the special form of valve chest e and valve having ports e¹ e² e³ and i, so
arranged that the arrest of the induction of the fluid causes an increase of pressure
and automatically reverses the valve, substantially as hereinbefore described and
illustrated by the drawings.
3. The general construction, combination, and arrangement of the several and
respective parts, together constituting my invention of improvements in the method
of and in means and appliances for measuring air, gas, and other fluids, substantially
as hereinbefore described and illustrated by the drawings.
