An Improved Means of Utilising Gas for Warming or Heating
Purposes.
I, DAN RYLANDS of Shepcote, Stairfoot near Barnsley in the County of York
Glass Bottle Manufacturer do hereby declare the nature of this invention to be as
follows:-
--
My present invention has for its object the utilization of gas whether made from
coal, oil, or other substances, for the purpose of warming houses and for other
similar purposes. According to my present invention I form, for placing in the
firegrate of a room or other place a piece, or it may be pieces, of firebrick which
is or are of any suitable shape and made so as to allow through a portion of them
passages for the air and for the gas. 1 so arrange these that the air which is
forced through the firebrick has a chance of being thoroughly heated before it
comes in contact with the gas. This may be done by forming the air passages
through the firebrick or other substance so as to cause them to travel along a good
amount of the heated surface. In any convenient position near to the fireplace
I fix a blower of suitable size which blower I prefer to actuate or drive by
electricity but it may be driven by any other suitable means. This blower forces
the air through the heated firebrick and brings it at the right point in combination
with the gas thus securing an intense heat. Enough space is allowed in the
firebrick for the due expansion of the heated gases so that the greatest amount
of heat practically possible can be secured from the burning gases. In some cases
the firebrick fixture is all in one piece and it has a sort of return hole to allow of
the waste products of combustion passing away up the chimney so that the heat

An Improved Means of Utilising Gas for Warming or Heating
Purposes.
I, DAN RYLANDS of Shepcote Stairfoot near Barnsley in the County of York
Glass Bottle 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 :-
My present invention has for its object the utilization of gas whether made from
coal, oil or other substances, for the purpose of warming houses and for other similar
purposes.
According to my present invention I form for placing in the fire grate of a room
or other place a piece, or it may be pieces of firebrick which is or are of any
suitable shape and made so as to allow through a portion of them passages for the
air and for the gas.
I so arrange these that the air which is forced through the
firebrick has a chance of being thoroughly heated before it comes in contact with
the gas. This may be done by forming the air passages through the firebrick or
other substance so as to cause them to travel along a good amount of the heated
surface. In any convenient position near to the fireplace I fix a blower of suitable
size which blower I prefer to actuate or drive by electricity but it may be driven
by any other suitable means. This blower forces the air through the heated
firebrick and brings it at the right point in combination with the gas thus securing
an intense heat. Enough space is allowed in the firebrick for the due expansion
of the heated gases so that the greatest amount of heat practically possible can be
secured from the burning gases.
In some cases the firebrick fixture is all in one piece and it has a sort of return
hole to allow of the waste products of combustion passing away up the chimney so
that the heat given off into the room is pure and only such as is given off by the fire-
brick block. Where the setting is for a kitchen I arrange such a shape of block that
the blow flame can pass through a suitable hole or holes in the firebrick block and
play direct upon the kettle or pan or other article that it is desired to heat.
In applying my present invention to apparatus for gas cooking I place in the
cooking apparatus an air pipe and connecting pipe for driving in the air to get
heat and I so connect this with the blower that a sufficient amount of hot air can
be sent in along with the gas to greatly economise the quantity of gas required.
In large establishments or mansions I prefer to have one large blower in the
basement or kitchen driven in any suitable manner and in this case the air is
conducted to each fireplace in the house by means of suitable pipes and it is
only necessary in lighting a fire to turn on the air at the same time as the gas.
In some
cases I prefer to carry the waste products of combustion in pipes
which pipes are made to traverse round upper rooms such as bedrooms in order
to heat them and to keep them at an equable temperature.
To illustrate my invention, I append hereto the accompanying sheets of
drawings, in which
Figs. 1, 2, 3 and 4, show an arrangement of open gas stove in which the air
needed for combustion is heated before mixing with the gas.
In Figs. 5 and 6 the front of the stove is closed, the escaping beat and
products of combustion being led away and utilised for the heating of upper
rooms as shown by Fig. 6.
Fig. 7 is an elevation in section, and Fig. 8 a plan view of a block of fire-
brick or other suitable material well adapted for gas-cooking purposes.
Fig. 9 shows in sectional elevation a gas and air mixing apparatus, and
Fig. 10 (also partly in sectional elevation) illustrates the application of the
gas and air mixing apparatus and the method of heating the incoming air supply
as applied to a gas cooking oven.

page_text: In Figs. 1 and 2, which are in sectional elevation a is an open stove of firebrick
or other refractory material, bb a passage or port formed in the interior of the
fixture whereby the incoming cold air supply is heated and brought to a high
temperature before mixing with the gas supply by reason of the great amount of
heating surface presented by the convulated containing walls of the port; c the air
supply pipe conveying air under slight pressure from a blower fan or air compressor,
to the inlet portion 6 of the port b; from whence it passes in a right and left and
downward direction, as shown by the arrows in Fig. 2, till passing through port d
it enters the mixing chamber e where, combining and mixing with the gas escaping
from the perforations in the gas supply pipe f, the now inflammable mixture leaves
the mixing chamber through the perforations 9 9, ignites in the open-fronted
combustion chamber producing intense heat and perfect combustion as a result of
the application of heated air to mix and combine with the gaseous fuel.
The stove being self-contained can be placed in any convenient position in the
room or place to be warmed. A ready means of connecting it to a register or
other grate is shown by Fig. 4 where the spent heat passes away through the
outcast flue i to the flue of the chimney. The greater portion of the outer walls
of the stove being radiant and heat-giving off surfaces, it follows that the heat
produced will be utilised in the room to be warmed, and not pass away unutilised
to the chimney flue.
In Fig. 5 a stove is shown in sectional elevation having the frout closed, and the
air heating port or passage bb arranged as shown. The perforated gas pipe f,
mixing chamber e and perforations 9 9 are of similar construction and arrangement
to those already described in reference to Figs. 1, 2 and 3. The gaseous flame
being entirely enclosed by outer walls will result in the heat given off by the stove
being pure and only such as given off by the firebrick of which it is composed.
Or instead of the stove being formed with an enclosed front, a door or doors may
be provided in which case the stove may be used as an open or closed stove at
pleasure. If formed as a closed stove a small opening (Fig. 5) is provided for
igniting and inspecting purposes.
In Fig. 6 the application of a stove heating a lower and an upper room
is shown.
In sectional elevation at Fig. 7, and partly sectional plan view at Fig. 8 is
shown a form of fire clay block or fixture well adapted for culinary purposes; kis
the furnace; the heated air admission tap, m an annular port communicating
with the shallow circular port n formed under the bottom of the furnace, o the gas
admission tap communicating with the perforated pipe pas shown. The furnace
is provided at its upper portion with an opening 9 on which opening any vessel or
utensil that it may be desired to use can be placed; is the outcast flue. The
air on being admitted by tap 1, annular port m, and circular port n around the
outer walls and bottom of the furnace, will become highly heated by reason of
the conductivity of the walls of the furnace, resulting in perfect combustion and a
very economical consumption of gas.

Fig. 9 shows in sectional elevation a gas and air mixing apparatus in which is
the air admission tap, t the mixing chamber, x the gas admission tap communicating
with the perforated nozzle pipe y as shown.
Fig. 10, which is partly in sectional elevation, illustrates the application of the
air and gas mixing apparatus and the method of heating the incoming air supply,
as applied to a gas cooking oven, from which it will be seen that the incoming air
becomes heated as it passes along in the direction of the arrows shown in the port
or passage provided for it under the bottom of the oven, leaving such port through
curved pipe
2 air tap s, it enters the mixing chamber t, where after mixing with
the gas it is by pipe 3 led into the interior of the oven and issues from the pipe
through the usual perforation.
A blower or fan placed in any convenient position and driven by an electro motor
furnishes a ready means of providing the air supply required for the purposes of
my invention.
