PROVISIONALI SPECIFICATION
Improvements in Gas Reversing and other Valves Applicable to
Gas Regenerative Furnaces.
GEORGE ALFRED DANIE, Engineer, 3, Richmond Terrace, Bassaleg, JOHN
WILLIAMS, Jr., Steel Works Manager, Rogerstone, Tydu, Newport, Mon., do hereby
declare the nature of this invention to be as follows:-
This invention relates to an arrangement by which the direction of the flow of the
gas through a regenerative gas furnace may be reversed as required.
According to this invention we employ a valve casing, covering the flue passages
and connected above to a gas box and having 2 movable valves within which when
raised or lowered simultaneously direct the flow of the gas to either end of furnace, &
the waste products from the other end of the furnace to chimney, the said valves being
actuated by movable levers, side rods, or other mechanical means from the furnace
standing,
The seating for valves has a continuous trough to carry either sand water, or other
suitable material or liquid for sealing.
When water or other liquid is used the trough of seating is connected by means of
The
suitable piping to the main water supply with an adjustable or regulating cock.
level of water is maintained by an adjustable overflow, both of which are outside of
valve casing.
When sand or other refractory material is used for sealing the whole of the water
connections may be discarded.
The valves are duplicate & balanced requiring little or no power to manipulate.
They may be inspected while the furnace is working.
The valve is so arranged that the depth of the seal can be so adjusted as to be
suitable for any force of draught & thereby ensure perfect sealing under all con-
ditions.
It is particularly adapted for high temperatures.
The valve is actuated by means of levers & rods outside of valve casing (which is
clear of all heat) & ensures perfect action at all times, in most other types a great
portion of the gearing is within the casing which gets burnt.
The valve as herein before described may be removed inspected or replaced, without
interfering with any flue or other part of the furnace.
Dated this 3rd day of July 1897.

We, GEORGE ALFRED DANIEL, Pen-y-dre Tydu, Newport, Mon., Engineer (late of
3, Richmond Terrace, Bassaleg, in the County of Monmouth), and JOHN WILLIAMS, Jr.,
Steel Works Manager, Rogerstone, Tydu, nr. Newport, in the County of
Monmouth, 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 :-
Our invention relates to an arrangement by which the direction of the flow of
the gas through a regenerative gas furnace may be reversed as required.
According to our invention we employ a valve casing covering the flue passages,
& connected above to a gas box, and having two movable valves within, which
when raised or lowered simultaneously direct the flow of the gas to either end of
the furnace, and the waste product from the other end of furnace to chimney.
The said valves being actuated by movable levers, side rods, or other mechanical
means from the furnace standing.
The seating for valves has a continuous trough to carry either sand, water, or
other suitable material or liquid for sealing.
When water or other liquid is used the trough of seating, is connected by means
of suitable piping to the main water supply with an adjustable or regulating cock.
The level of water is maintained by an adjustable overflow both of which are
outside of valve casing.
When sand or other refractory material is used for sealing the whole of the water
connections may be discarded.
The valves are duplicate & balanced requiring little or no power to manipulate,―
they may be inspected while the furnace is working.
The valve is so arranged that the depth of the seal can he so adjusted as to be
suitable for any force of draught & thereby ensure perfect sealing under all
conditions.
It is particularly adapted for high temperature, the valve is actuated by means of
levers and rods outside of valve casing (which is clear of all heat) and ensures perfect
action at all times, in most other types a great portion of the gearing is within the
casing which gets burnt.
The valve as hereinbefore described may be removed, inspected, or replaced without
interfering with any flue or other part of the furnace.
In order that our invention & the manner in which it may be performed, may
be well understood we will describe with reference to the accompanying drawing, a
device constructed in accordance therewith.
Figures 1 and 4 are vertical sections at right angles to each other, Figure 2 a
front elevation and Figure 3 a plan with casing and one valve removed.
B is a casing fixed to baseplate F through which pass the openings C leading to the
respective regenerators and furnace & the opening D leading to the chimney.
The inlet E for gas also opens into the said casing B. The inner chambers marked A
are the valves proper. They are of a sufficient size to cover the opening D and one
or other of the openings C. The baseplate F is recessed for holding the sealing
material shewn at G into which the edges of the inner chambers or valves proper A
are received, on the ends of the inner chambers or valves proper A are fixed the
wrought iron straps b, through which pass the spindles a firmly fixed at a given
position. These spindles are carried each end in pedestals cast in one with
baseplate F, on the end of each spindle is arranged a soled quadrant c to which is

page_text: bolted lever d, by means of set screw i, the other end of spindle a is secured by an
ordinary split pin and collar. The lever d is connected up with rods f and adjustable
coupling box h, the connection to furnace standing by an extension of rod g.
The main water supply is joined up to a three way cock K by means of pipe m
and is carried from the cock through casing B by pipes j which are perforated
right across.
The three way cock K is actuated by levers from e so that the water may be
reversed same time as valve A.
A separate pipe can be arranged to keep supply level in trough on baseplate
if found necessary.
An adjustable sluice
pressures of draught.
leading to overflow pipe is so arranged to suit all
Inspection doors I and J may be opened at any time to examine valve A.
The regenerators are of course in the line of the flues C between the valve &
furnace.
D is the chimney flue.
The valve thus made gives a full area opened to either C or D & is not injuriously
affected by heat or flame, & is therefore specially suitable for high temperature
gas making a perfect seal under all conditions of temperature.
The action of valve will now be readily seen. When the connecting rod g is pulled
forward or pushed backward one valve couples the regenerator flue C to the chimney
flue D & opens the other regenerator flue C to the gas and vice versa.
.
Having now particularly described & ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
&
1. In or for regenerative gas furnaces a valve consisting of a casing such as B into
which the flue passages & the inlet for gas, and the inlet to the chimney open,
two inner chambers A provided with means for operating them from outside the said
casing, so that it can be adjusted to connect the regenerator flues alternately with
the chimney and inlet for gas, the said casing to be provided with a seal or lute for
the reception of the lower edges of the said inner chambers, substantially as herein-
before described.
2. A device for reversing the direction of flow of gas in regenerative furnaces, the
said device being constructed substantially as hereinbefore described and illustrated
in the accompanying drawing.
