A Pot and Tank Gas Furnace Combined for Use in Glass Melting
and other kindred Trades.
I JOSEPH YELLAND of No. 22 Melbourne Street. York in the County of York, Gas
Furnace Builder do hereby declare the nature of this invention to be as
follows:-
This Invention relates to a pot and tank gas furnace combined the object being to
construct such furnace that it shall be more effective than those at present in use.
In carrying out my invention I construct the furnace as follows:-
The lower part has formed at each side thereof pockets or reservoirs for the gas to
pass into.
Next to these gas pockets and towards the inside of the furnace are provided metal
or glass pockets for reception of any metal or glass that may come off the seige to be
hereinafter mentioned.
Further inwards are air pockets from which the air is passed as may be
required to circulate through the furnace.
Between these air pockets is an air box and passages for supply of air into the said
pockets and to the flues above the furnace.
Above these pockets is the furnace provided with air flues for passage of air under
the furnace and over these are placed four or more seiges and tanks and at the outer
ends are (what are well known as) pots.
In the upper part of the framework and between the pots are four or more huds
which purify the gas. These huds are small crucibles with small holes in the centre
and made of clay.
•
The gas passes from one of the gas pockets through a valve into the pot thence
over the tanks and through the huds and then through the seige into the other gas
bocket.
The air passes under the seige and is consequently made much hotter than in
ordinary furnaces. It is then taken back through an air box on the valve of air
chamber to furnace.

page_text: The metal or glass pockets being placed one between each gas and air chambers at
each end receive any metal or glass coming off the seiges.
By this arrangement the depth of foundation is considerably reduced, the cost is
lessened and a more effective furnace is obtained.
The gas and air is lighted at the entrance of the furnace seige and travels across
the tank to the other gas and air ports between the pots and tanks where is an air
flue to cool the tank and partition such partition being between the pots and tank,
the pots come out at the sides of the gas and air ports or valves.
The tank is a large square receptacle made of large bricks in which is placed the
ingredients for making the glass.

I JOSEPH YELLAND of No. 22 Melbourne Street York in the County of York, Gas
Furnace Builder 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 relates to a pot and tank gas Furnace combined for use in glass
melting and other similar trades, the object being to construct such furnace that it
shall be more effective than those at present in use.
In order that the said Invention may be readily understood there is annexed hereto
two sheets of drawings reference being had to the figures and letters marked thereon,
that is to say :-
Fig. 1 shows the furnace complete in end view.
Fig. 2 an internal view shows in section the air valves and tanks.
Fig. 3 shows in side view the valves, air flues and huds.
A are the gas pockets; B the metal pockets; C the air pockets; D the air box ;
E the air flues; F, F' the valves; G the seiges; H the tanks and I the huds; K are
the pots.
The lower part has formed at each side thereof pockets or reservoirs A, A¹ for the
gas to pass into. Next to these gas pockets A, A' and towards the inside of the furnace
are provided metal B to receive any metal that may come off the seiges pockets G.
Air pockets C are provided from which the air is passed through valves F into flues E
into furnace L.
Over this furnace L are provided four or more seiges G, serving as platforms for
tanks Hand at the outer ends are (what are known as) pots K. Above the tanks H
and between the pots are huds I which consist of small crucibles or pots with holes in
the centre and are made of clay and inserted into the tank.
The gas passes from one of the gas pockets A through valve F over the pot K
thence over the tanks H and through huds I whence it passes over second pot K
and through the seiges G into the second gas pocket A' and is then dispersed.
The air passes from air pocket (through valve F¹ thence under the seige and is
consequently made much hotter than in ordinary furnaces. It is then taken back
through an air box of air chamber C to the furnace.
The metal pockets B being placed one between each gas and air chamber A. A¹. C.
at each end receive any metal coming off the seiges G.
By this arrangement the depth of foundation is considerably reduced, the cost
lessened and a more effective furnace is obtained.

page_text: The gas and air is lighted at the entrance of the furnace seige and travels across
the tank to the other gas and air pots between the ports and tanks.
The tank is a large square receptacle made of large bricks in which is placed the
ingredients for making the glass.
Having now described the nature and particulars of the said Invention and
in what manner the same is to be performed I declare that what I claim is :-
A pot and tank gas furnace combined for use in glass melting and other kindred
trades as herein set forth and shown by the drawings.
