PROVISIONAL SPECIFICATION.
Improvements in Gas Generators or Producers and Furnaces and
Appliances for Smelting Glass, for Melting and Heating Metals,
Alkalies, and other Substances; and for Heating Steam Generators,
and for like purposes.
1, WILLIAM WINDLE PILKINGTON of St. Helens in the County of Lancaster,
Glass Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The invention relates to generators or producers and furnaces with their
accessories used for heating generally in which gas is generated and burned at
pressure above that of the atmosphere and with measured quantities of fuel
and air.
The objects are to obtain uniform quality of combustible gas, easy regulation,
efficient heating and durability of parts, a mellow flame being first produced with
increased heat afterwards.
For the above purpose I feed the fuel into the top of the generator or
producer through any suitable measuring box or appliance, and I make such
generator with a receiver or coking block beneath the feed opening, such receiver
or block being carried by cross arches or bearers. The hearth of the producer is
beneath the fuel receiver or coking block and has two or more symmetrically
placed air supply boshes.
The air supply is lead from a blower into a delivery box from where it is
divided into two streams, one passing to the producer and the other to a
gas box.
The gas passes off from the generator or producer to the gas box where it
meets with the air and passes into the furnace.
The gas box is made with one or more air tuyers or blow bricks and with one
or more parts opposite thereto opening into the furnace.
The generator or producer and furnace are combined, and the generator or
producer may in some instances be used separately from the furnace, and with or
without air regenerators.
The generator or producer is combined with two air regenerators operated
alternately by means of lifting valves.

I WILLIAM WINDLE PILKINGTON of St. Helens in the County of Lancaster,
Glass Manufacturer, 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 :-
The invention relates to generators or producers, and furnaces with their
accessories used for heating generally in which gas is generated and burned at
pressure above that of the atmosphere and with measured quantities of fuel
and air.
The object are to obtain uniform quality of combustible gas, easy regulation,
efficient heating and durability of parts, a mellow flame being first produced with
increased heat afterwards.
For the above purpose I feed the fuel into the top of the generator or producer
through any suitable measuring box or appliance, and I make such generator with
a receiver or coking block beneath the feed opening, such receiver or block being
carried by cross arches or bearers. The hearth of the producer is beneath the fuel
receiver or coking block, and has two or more symmetrically placed air supply
tuyeres.
The air supply is lead from a blower into a delivery box from where it is divided
into two streams, one passing to the producer, and the other to a gas box.
The gas passes off from the generator or producer to the gas box where it meets
with the air and passes into the furnace.
The gas box is made with one or more air tuyeres or blow bricks and with one
or more ports opposite thereto opening into the furnace.
The generator or producer and furnace are combined, and the generator or
producer may in sorne instances be used separately from the furnace and with or
without air regenerators.
The generator or producer is combined with two air regenerators operated
alternately by means of lifting valves.

The drawing appended is a view partly in vertical section and partly in elevation
gas generator or producer and furnace and appliances constructed in accordance
with my invention. a is a hopper into which the fuel is fed. b is a neck leading
to the generator or producer. c is a slide or measuring box having an aperture d
therethrough. The said slide or measuring box is moved to and fro between the
hopper and the neck to carry the fuel from the hopper to the neck. The quantity
of fuel fed is regulated by the speed at which the slide or measuring box moves;
by varying the position of the hopper; or in any other convenient way. Any
suitable motor is used to actuate the slide or measuring box. Rotary or other
measuring boxes of any well known construction may be used. e is the generator
or producer made substantially in the usual way. e is a receiver or coking block
situated beneath the neck b, on which the fuel falls and is coked before reaching
the bottom of the generator or producer. The said block is conveniently carried
by four arches f. 9, is the hearth of the generator or producer beneath the fuel
receiver or coker e. h are two air supply tuyeres symmetrically placed in this
case, diametrically opposite so as to keep the combustion central. is a delivery
box into which air from the blower enters and from which it is delivered down
pipes to the tuyeres and thence into the generator or producer and down a pipe
or pipes k into the gas box l. m way or ways leading from near the top of the

generator or producer through which the gas passes to the gas box l. The gas
box is made with one or more tuyeres or blow bricks n extending across the
furnace through which air is delivered into the said gas box where it meets and
nixes with the gas from the generator or producer. The said gas box is also
provided with a port or ports n' extending across the furnace in front of the air
tuyeres or blow bricks n through which the mixed gas and air enter the furnace o.
There are two air regenerators p preferably side by side connected by ways q at
the top with a valve r, and at the bottom by ways s, with a valve t. The furnace o
and the air delivery box communicate with the seat of the valve r by the
ways and v, whilst the chimney flue w and the blower delivery pipe a
communicate with the seat of the valve t. As shown, air is passing from the
blower past the valve t up through the regenerator p and thence past the valve r
into the delivery box i, whilst the waste gases from the furnace are flowing past
the said valve down through the second regenerator behind p and past the
valve t to the way w leading to the chimney flue. When the valves are lifted,
reversed, and lowered on to their seats the passage of the air and gases through
the regenerators are reversed. The valves used, are of any suitable construction
for reversing the flow of gases to and from regenerators, but should, when air
under pressure is used, as in this invention, be lifted from their seats before
reversal. The furnace may be of any usual construction according to the purpose
for which it is required such as smelting, melting, or steam raising, and the tuyeres
or other parts are clothed or made with fire clay where necessary.
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 apparatus in which gas is generated and burned at pressure above that
of the atmosphere, a producer or generator combined with a feed box and receiver
or coking block substantially as set forth.
Second. In apparatus in which gas is generated and burned at pressure above
that of the atmosphere, a producer or generator combined with symmetrically
placed air supply tuyeres.
Third. In apparatus in which gas is generated and burned at pressure above that
of the atmosphere, a generator or producer combined with a receiver or coking
block and symmetrically placed air supply tuyeres.
Fourth. In apparatus in which gas is generated and burned at pressure above
that of the atmosphere, the combination of a generator or producer and furnace
with an air box from which air is delivered both to the said generator or producer
and furnace.
Fifth. In apparatus in which gas is generated and burned at pressure above
that of the atmosphere a generator or producer with ways leading to a gas box
provided with air tuyeres or blow bricks and ports opposite thereto opening into
the furnace.
Sixth. In apparatus in which gas is generated and burned at pressure above that
of the atmosphere, the combination of a producer or generator, two air regenerators,
and lift reversing valves, substantially as and for the purpose set forth.
Seventh. Apparatus for generating or producing and burning gas at pressure
above that of the atmosphere substantially as set forth.
