I SHIRLEY BOWDEN of 33 Southampton Buildings Holborn in the County of
Middlesex carrying on business as a Patent Agent under the style or firm of
"Elt & Co" do hereby declare the nature of my Invention for A NEW OR
IMPROVED COMBINED PRESSURE REGULATOR AND ECONOMISER APPLICABLE TO
GAS STEAM WATER AND OTHER PIPES" to be as follows:-
The object of this Invention is to check the uneven flow or pressure of gas,
water, steam and other liquids and vapours thus effecting in respect of gas a great
saving in consumption.
Such Invention consists of an external and internal cone-tube or cone-tubes
combined or separate, inserted fixed cast or formed in the delivery pipe-By
calculated diameters and distances from point of discharge such pressures are
brought to uniformity by the check on the external part of the cone-tube or tubes
causing a recoil pressure through the internal cone tube or tubes thus forming a
steady delivery and thereby in gas effecting a saving of from twenty to thirty
per cent.
The mode of operation is as follows:-The inside of delivery pipe having been
prepared by- a rimer, screw tap, or otherwise, the cone tube is inserted with
external or small end facing the pressure. The force of gas, water steam or other
substance being applied strikes against the external part of the cone thereby
cushioning and causing a certain recoil pressure to take place against the opposing
pressure and thus producing a concentrated force against the sharp edge of external
cone tube, having entered the orifice it is allowed immediate expansion in the
internal portion of cone tube.
.
The size of orifice as compared with the delivery pipe under these circumstances
causing and effecting a uniformity of discharge The cone-tubes may either be
hexagonal, octagonal or of any other convenient form.

page_text: I, SHIRLEY BOWDEN of 33 Southampton Buildings, Holborn, in the County of
Middlesex carrying on business as a Patent Agent under the style or firm of
Elt and Co do hereby declare the nature of my Invention for A NEW OR IMPROVED
COMBINED PRESSURE RECULATOR AND ECONOMISER APPLICABLE TO GAS, STEAM,
WATER, AND OTHER PIPES 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 this Invention is to check and regulate the uneven flow or pressure
of gas, water, steam, and other liquids and vapours thus effecting as respects gas a
considerable economy in consumption.
Such Invention consists of an external and internal cone tube or cone tubes,
either combined or separate, inserted, fixed, cast or formed in the delivery pipe
whereby and by calculated diameters and distances from the point of discharge
such pressures are brought to uniformity, by the check on the external part of the
cone tube or tubes causing a recoil pressure through the internal cone tube or
tubes, thus forming a steady delivery and thereby in gas effecting a saving of from
20 to 30 per cent.
In the accompanying Drawings I have shewn as examples four methods of
applying this Invention to great advantage-Figures 1 and 2 illustrate the cone
tube fixed in the steam pipe of an engine-Figure 3 shews the cone tube fitted in
a water hose-Figure 4 shews the cone tube fitted in a gas pipe-Figure 5 shews
the cone tube affixed to or connected with a gas burner, and Figures 6 and 7 shew
longitudinal and end sections of such cone tube-Similar letters of reference
indicate corresponding parts-A being the cone tube-B the delivery pipe-ând
C the gas burner.
The operation of my Invention is as follows:-The inside of the delivery pipe
having been prepared by a rimer, screw tap, or otherwise, the cone tube is inserted
therein with its external or small end facing the pressure-When the force of the
gas, water, steam or other liquid or vapour is applied such pressure strikes against
the external part of the cone, thereby cushioning and causing a certain recoil
pressure to take place against the opposing pressure and thus producing a con-
centrated force against the sharp edge of the external cone tube and having entered
the orifice, it is allowed scope for immediate expansion in the interior of the cone
tube The size of the orifice as compared with the delivery pipe under these
circumstances causing and effecting a uniformity of discharge-The cone tubes may
either be made separate and inserted in or otherwise affixed to the delivery pipe,
or they may be cast or otherwise formed thereon or therein, and they may assume
other shapes than that of a true cone shape, such, for instance, as hexagonal or
octagonal, or any other convenient form-but I prefer to employ those of a cone
shape as shewn in Figures 6 and 7.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is;
1
I
1. The insertion or introduction into a delivery pipe of an external and internal
cone tube or cone tubes with the external portion and small orifice facing the
pressure substantially as described, and shewn in Figures 2, 3, and 4 of the
accompanying Drawings.
2. The combination of an external and internal cone tube or cone tubes with a
gas burner substantially as described, and shewn in Figure 5 of such Drawings.

page_text: 3. The combination of an external and internal cone tube or cone tubes either
singly or conjointly with the pipes, tubes or vents of boilers, vats, or other cisterns
or receptacles for holding or conveying gas, water, or steam or smoke, or any other
liquid, fluid or vapour substantially in the manner and for the purposes hereinbefore
specified.
