Improvements in the Construction of Port Mouths of Regenerative
Gas Furnaces.
We DAN RYLANDS of Hope Glass Works, Stairfoot, near Barnsley in the County
of York, Glass Bottle Manufacturer, and RICHARD POTTER of Stairfoot aforesaid Gas
Furnace Builder do hereby declare the nature of our invention for IMPROVEMENTS IN
THE CONSTRUCTION OF PORT MOUTHS OF REGENERATIVE GAS FURNACES 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 so construct and arrange the Port Mouths in
Regenerative Gas Furnaces that the air and gas when issuing therefrom into the
furnace become quickly and effectually intermixed. By this means an economy of fuel
is attained inasmuch as the carbonic-oxide or other gas immediately takes up its
share of oxygen from the air by coming in contact therewith, so that there is less gas
escapes from the furnace unconsumed than is the case in Regenerative Gas Furnaces
having Port Mouths of the ordinary construction.
The hereunto attached drawings represent various forms of Port Mouths constructed
according to our present invention.
It must be well understood that the various forms of months herein illustrated inay
be modified in form to suit any particular requirements without interfering in any
way with the essential part of our invention.

page_text: On Sheet 2, Figs. 8, 9, 10, 11 and 12 are front views of a development of our
improved Port Mouths and Fig. 13 is a longitudinal section on line z, z of Fig. 8.
The same letters designate similar parts throughout the several views.
Referring to Figs. 1 to 7, g are the gas Port Mouths which are separated from the
air Port Mouths by the partition p, and the air Port Mouths a are enclosed by the
casing c.
In Figs. 1, 2, and 6, where the air Port Mouths a entirely surround the gas Port
Mouths g, we connect the partitions p and casing c with suitable webs w, thus making
the Port Mouth in one piece of suitable refractory material.
When it is desired to have the Port Mouths constructed in two or more lengths they
may be made with joints tongued and grooved as shown at Fig. 6.
Referring to Fig. 7, the gas Port Mouths g are connected to the Regenerators s, s
by the Ports g', g¹, and the air Port Mouths a, a, are connected with the
Regenerators T, T, by means of the Ports a¹, a¹.
The Ports a¹ a¹ are preferably arranged one on either side of the Ports g¹ so that
two air Ports a¹ a¹ connect the Regenerators T T to the Port Mouths
while one gas
Port g connects the Regenerators s, s, to the Port Mouth g.
a,
Referring to Figs. 8 to 13 on Sheet 2, the Port Mouths have air passages a² and a,
and a gas passage g, an extra partition p¹ separates the air passage a³ from the gas
passage g; and a passage a connects the air passage a³ to the outer air passage a.
These improved Port Mouths may be connected to the Regenerators in the way
shown at Fig. 7 on Sheet 1.
These improved Port Mouths may be made in two or more lengths and tongued and
grooved as shown at Fig. 13.
These developments of our improved port Mouths may be altered in form to suit
special requirements without departing from the points claimed in our invention as will
be well understood.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, we declare that what we claim is
1 In the Port Mouths of Regenerative Gas Furnaces the arranging of the passage
for the air and the passage for the gas so that the passage for the air either partially or
wholly surrounds the passage for the gas, or the passage for the air is formed above
and below or on all four sides of the passage for the gas, substantially as hereinbefore
described and illustrated in Figs. 1 to 7 or any mere modification thereof.
2 The construction of port mouths for Regenerative Gas Furnaces so that in
addition to the passage for the air surrounding the passage for the gas there is a
passage for the air in the centre or under the passage for the gas, for a further supply
of air to enter substantially as herein described and shown at Figs. 8 to 13 or any
mere modification thereof.
