Improvements in or Connected with Stoves to be Heated by Gas or
other Fuel for Air Warming and Ventilating Purposes.
I JOHN LOWE, of 42, Green Street, Park Lane, Grosvenor Square, Middlesex, M.D.
do hereby declare the nature of my invention to be as follows:-
:-
The object of this invention is improvements in or connected with stoves to be heated
by gas or other fuel for air warming and ventilating purposes.
The stove consists of a case made of wrought iron or earthenware, having flanges
inside for the support of a series of earthenware or metal plates arranged horizontally
and so constructed as to form a long continuous tube for the conveyance of smoke and
heated air.
The plates are composed of fireclay or other earthenware or metal can be adapted.
They may be plain, in which case they would have an opening at alternate ends to
allow of the smoke passing upwards from one plate to the other; or the plates may
have grooves on one or on both surfaces; the divisions alternately falling short of the
margin, so that when placed in position a continuous tube is formed. At alternate and
opposite ends or corners is an opening to complete the communication with each layer
of the plates or tubes above and below.
The stove may be of any angular shape or circular. In circular stoves the plates
are arranged that the communication between them is alternately central and lateral.
At the bottom of the stove is a chamber which contains the heating apparatus fitted
with gas jets but a brasier or furnace for burning charcoal or other fuel can be
adapted.
The air is admitted by a pipe into this chamber, and the chamber is closed by a
closely fitting door so that no noxious vapour can escape into the room. Both the
supply pipe and that for escape of smoke are conducted to a flue or to the external air
and have no communication with the apartment.
The heated air passing through the stove yields more of its caloric to the plates or
tubes and it is claimed that by this means a great saving in heating power is effected.
J

page_text: It is also claimed that there is no possibility of the air of the apartment being
contaminated by gas or consumed air.
Another part of the invention is for the supply of fresh air from the outside which
warmed before escaping into the room.
An outer case of iron or earthenware surrounds the stove on one or more sides. ;
This case is closed below but open above. At the bottom of the case a pipe or pipes
- convey fresh air from outside room into the space between the stove and its case and
the air passing over the heated surface passes, warmed, into the room.
The pipes for supplying fresh air may, if necessary, be arranged inside the stove.
The shell or casing of the stove may have gills or projections upon it for the diffusion
of heat radially or otherwise.

I, JOHN LOWE, of 42 Green Street, Park Lane, Grosvenor Square, Middlesex, M.D.
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 object of my invention is improvements in or connected with stoves to be
heated by gas or other fuel for air warming and ventilating purposes.
The stove consists of a case A, such as I show at Figures 1 and 2 of the annexed
drawings made of wrought iron or earthenware having flanges B inside for the support
of a series of earthenware or metal plates C arranged horizontally and so constructed as
to form a long continuous tubė for the conveyance of the smoke and vapour to an
uptake or chimney D.
The plates C (composed of fireclay or other earthenware or metal) may be plain,
in which case they would have an opening at alternate ends to allow of the vapour
passing upwards from one plate to the other; or the plates may have grooves on one
or both surfaces; the divisions alternately falling short of the margin so that when
placed in position a continuous tube is formed.
At alternate and opposite ends or corners is an opening to complete the communica-
tion with each layer of the plates or tubes above and below.
The stove may be of any angular shape or circular. In circular as at Figures 3 and 4
the plates are so arranged that the communication between them is alternately central
and lateral as indicated by the arrows.
At the bottom of the stove is a chamber E which contains the heating apparatus
fitted with gas jets, but a brasier or furnace for burning charcoal or other fuel can be
adapted.
Air is admitted by a pipe F into this chamber to support combustion and to produce
circulation among the plates C, C, and the chamber is closed by a closely fitting door G
so that no noxious vapour can escape into the room. Both the supply pipe F and
that D for escape of smoke are conducted to a flue or to external air and have no
communication with the apartment.
The heated air passing through the stove yields most of its caloric to the plates C
and casing A or tubes, if tubes are provided and consequently a great saving in heating
power is effected.
Another part of the invention is for the supply of fresh air from the outside which
is warmed before escaping into the room.
An outer case H of iron or earthenware surrounds the stove on one or more sides.
This case H is closed below but open above. At the bottom of the case a pipe or
pipes I convey fresh air from the outer air into the space J between the stove and its

page_text: case H and the air passing over the heated surface passes warmed into the room by the
outlet K.
The pipes for supplying fresh air may, if necessary, be arranged to pass inside
the stove.
The shell or casing of the stove may have gills or projections upon it for the diffusion
of heat radially or otherwise.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A stove composed of two parts in one of which the heat from gas jet, lamp or other
source as circulated through between plates in a zigzag or to and fro direction and
provided with inlet and outlet for air which has no entrance into the room or apartment,
the heat of the stove A being conducted to a distinct air container or dilator J which
has an opening into the room or apartment for warming it, the construction being
substantially as shown in the annexed drawings.
