PROVISIONAL SPECIFICATION.
Improvements in or relating to the Distributing or Regulating
Valves of Regenerative Gas Furnaces for Steel Melting and
Analogous Purposes.
I ISAAC BEARDMORE of Lymington Lodge Bothwell in the County of Lanark
North Britain Gentleman do hereby declare the nature of this Invention to be as
follows:
or
My Invention relates to improvements in or relating to the distributing or
regulating valves of Regenerative Gas Furnaces for steel melting and analogous
purposes and has for its object to protect what is known as the "Butterfly
tongue valve from the action of the intense heat which causes the said valves as at
present constructed to become buckled up and thereby rendered ineffective when the
valve is required to shut close against its seating in the reversing regulating or closing
of the flow of air and gas.
In carrying out my Invention I construct the valve hollow to contain water
which is supplied to and taken from the hollow of the valve by a continuous
circulation.
The valve is carried by hollow trunnions for the conducting therethrough of the
water the junctions of the said trunnions with the water supply and outlet pipes being
effected in any suitable manner that will allow a free action of the valve and keep
the junction watertight.
The right and left seats for the reversing of the valve as required are also in the
carrying out of my said Invention constructed as water casings a circulation of water
being kept up through the said casings as described with reference to the valve itself.
As a further protection against the direct action of the heat, I may line the water
casings with fire brick or with regard to the valve I may form a double face thereon
with an air intervening space.
In the carrying out of my said Invention I may provide a strip of asbestos round
the edge of the valve to assist its efficient closing against its seats or I may modify
this arrangement by placing the asbestos lining on the faces of the seats.
In lieu of constructing the valve with a simple hollow portion as described the
water holder may take the form of a coil of piping through which the water is caused
to circulate continuously and this arrangement ensures an even circulation for the
benefit of the valve; I may however employ any other arrangement of tubes for the
purpose.

Improvements in or relating to the Distributing or Regulating
Valves of Regenerative Gas Furnaces for Steel Melting and
Analogous Purposes.
I, ISAAC BEARDMORE of Lymington Lodge, Bothwell, in the County of Lanark,
North Britain, Gentleman, 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 which relates to improvements in or relating to the distributing of
regulating valves of regenerative gas furnaces for steel melting, and analogous
purposes, has for its object, the protection of what is known as the "Butterfly"
or

page_text: Tongue" valve, from the action of the intense heat, which causes the said valves
as at present constructed to become buckled up, and thereby rendered ineffective when
the valve is required to shut close against its seating in the reversing, regulating, or
closing of the flow of air or gas:
In order that my-Invention may be properly understood, and readily carried into
effect, I will proceed to describe it with reference to the accompanying sheets of
drawings,, of which Figures 1 and 2, sheet 1, are elevation and plan respectively and
Figures 3 and 4; sheet 2; sectional elevation, and part sectional end elevation,
respectively of my said improvements.

In carrying out my said Invention, I construct (by casting or otherwise) the
"butterfly ог tongue" piéce A, Figures 2 and 3 of the valve, hollow for the
purpose of allowing a continuous circulation of water to be passed through
the interior of the said "tongue" piece, the said circulation being assisted by means
of one or more webs formed within the said "tongue" piece, as shown at a, Figures 2
and 3, and to allow of any air escaping which may gather inside the said "butterfly
or tongue piece, I mount near its top edge one or more brass screw pins al,
having an air hole drilled through them. The said "butterfly" or "tongue" piece is
carried by hollow trunnions a², forined on either side, the said hollów trunnions being
also employed as inlet and outlet openings, for the conducting therethrough of the
water which is supplied to and taken from the "butterfly or "tongue" pièce by
means of pipes a³, the junctions of the said pipes with the trunnions being effected.in
any suitable manner, preferably by means of ordinary packed stuffing boxes and
glands a, the said stuffing boxes being formed in the outer ends of the trunnions, and
having their outside formed as a hexagon a³, or square for the purpose of allowing a
suitable handle B, to be mounted on, the said handle being mounted on whichever
side is found most suitable for the convenient manipulation of the "butterfly" or
'tongue "piece of valve.
22
In accordance with my said Invention I also form the valve casing D (which has
the seat C, for the said "butterfly" or <
tongue" piece A, to work against formed on
it) as a hollow water casing for the similar purpose of allowing water to be continuously.
circulated through the interior of the said casing, and thereby tending to prevent the
intense heat from twisting or buckling up the said casing:
The said casing D) is provided (when casting or otherwise) with the necessary
openings d, near its bottom, preferably two on either side for the water inlet, and also
with the necessary openings d', near its top, preferably two on either side for the*
water outlet. The said openings preferably take the form of small man-holes; the
doors d², or covers' of which are secured in any suitable manner to the casing, and lat
the same time have the ends of the inlet and outlet pipes d³, screwed into them, thus
providing a very' efficient means for allowing of the cleaning of the inside of the valve
casing or pipes.
"
The valve casing is formed with two slots or openings E, one on either side for the
purpose of allowing the "butterfly" or
** tongue piece to be placed in position, or
taken out for repairs at any time, the lower ends of said slots being formed as the
outer parts of bearings, for the trunnions of the "butterfly or "tongue" piece to
work in, the top parts of the said bearings being formed on the ends of filling-in
pieces F. The said filling-in pieces F, being formed of a sufficient size to entirely fill
up the slots or openings B, formed in the valve casing, and they are also secured to
the said valve casing by any suitable means preferably by studs or pins'f, the joints
being effected in such a manner as to be air and gas tight.

رو
If found necessary I may line the edges or faces of the butterfly" or "
piece, or the seats of the valve with a strip of asbestos, or of any other-suitable
material.

'As à modification of the said höllow "butterfly or "tongue" piece of the valve
for allowing of the circulation of water, I may form the water holder of the said
"butterfly." or 6
tongue piece as a coil of piping, or any other arrangement of
tubes or pipes to ensure an even circulation of the water for the benefit of the' said
valve.

page_text: As a modification in the carrying out of my improvements, I may in some cases
dispense with a water circulation through the butterfly," by making the said
butterfly solid, and relying upon the water. casing D, to keep the valve facings
tight; and I may also, in some cases, dispense with the slots E, in the casing.
The circulation of the water both through the "butterfly," and the casing, may be
effected in any convenient manner, such as by pumping, or by a head of water.
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 I
claim is―
"
"
First In distributing or regulating valves of regenerative gas furnaces for steel
melting and analogous purposes, constructing the "butterfly or "tongue piece A,
as a water casing, whereby a continuous circulation of water is caused to pass there-
through, substantially as hereinbefore described, and shewn in figures 1, 2, 3 and 4, of
the accompanying drawings.
Second Inbutterfly valves of regenerative gas furnaces, constructing the
casing D to contain water, so that a continuous circulation of water is caused to
pass therethrough, substantially as herein before described with reference to the
accompanying drawings.
