PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating, Illuminating, Ventilating,
and Cooking.
I, WILLIAM BRUCE, of 35, Cliff Road, Leeds, in the County of York,
Clerk of the Works, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to increase the efficiency and safety of gas fires
or stoves for heating and ventilating purposes and to construct the apparatus in
such a way that the air supply to the building can he admitted at or near the
heating surface of the apparatus and without mixing the incoming air with the
products of combustion; and owing to its construction the air will not pass or
circulate more than once over the heating surface of the apparatus.
I, propose to construct a door, panel, or other suitable framed opening, prepared
for glass or mica, in the heating apparatus, forming the front part of the
illuminating section, as a chamber; and inside the said chamber will be fixed
illuminating gas burners and each illuminating part or section of the apparatus
will be constructed with an air supply for combustion, as describe in my
Specification, No. 7978, of 1894. The back of the apparatus will be constructed
with a large heating surface to warm the air, admitted from the outside to circulate
over the hot back and sides of the apparatus; and the warmed air to be
discharged into the building, as required, but preferably at or near the floor level.
To obtain additional heating power, when required, I, propose to use the heating
apparatus, as described in my aforesaid Specification No. 7978, of 1894, fixed at
the back of the illuminating heating and ventilating apparatus herein described.
Above or below, at or near the side of the combined illuminating, heating and
ventilating apparatus 1, propose to fix one or more ovens for cooking purposes,
when required, with the burners in chambers, supplied with a sufficient quantity
of air for combustion and flues to remove the products thereof, to prevent the said
products from mixing with the inside atmosphere.

Improvements in Apparatus for Heating, Illuminating, Ventilating,
and Cooking.
1 WILLIAM BRUCE of 35 Cliff Road Leeds in the County of York, Clerk
of the Works, 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 this invention is to improve the heating and ventilation of
buildings and to increase the heating efficiency of the gas or oil burnt in the
beating and illuminating chambers of the apparatus and in such a manner that
the air supply to the building is shut off from the flame and products of combustion
and not reheated nor allowed to circulate round the warming surface of the
otus

page_text: My invention consists in the method of construction shown by the drawings
and herein described and I believe with a higher efficiency than has been obtained
heretofore and combined with the illuminating enclosed chamber giving the
appearance of a fire burning behind the glass, mica or other transparent casing
that is fixed between the flame and the inside atmosphere of the house and
completely shutting off and extracting the products of combustion from the inside
of the building.
Figs. 1. 2. & 3. show the plan elevation and section of the warming, ventilating
and illuminating apparatus. The heating apparatus as described in my Specification
No. 7978, 1894 is shown fixed at the back of the illuminating front with provision
for a supply of warm or cold air at the floor level or the air can be discharged_at
the sliding grate in the casing above the top of the illuminating chamber. The
supply of air to the illuminating chamber will be taken direct from the cold air
flue with a backflap valve of mica or other suitable material to prevent a back-
draught from the chambers, & the heating chamber of the apparatus will be
supplied with air for combustion from the illuminating chamber and regulated by
a sliding grate or valve as shown in the section Fig. 3. The illuminating section
is provided with an extraction flue pipe and is shown on the drawing, connected to
the top chamber of the heating apparatus. The drawings show a gas supply pipe
with three burners fixed in front of a curved reflector. In the illuminating
chamber I propose to use, candles, oil, or electricity for illuminating purposes as
may be found most convenient.
Figs. 4 & 5 show the arrangement of two sections of the heating and ventilating
apparatus fixed behind the ovens with the illuminating chamber fixed on the side
of the air flue above the oven top.
Fig. 5 shows the arrangement of flues for the supply of fresh air to the building
and the provision that is made for protecting the inside from the products of
combustion. Three or more ovens can be fixed side by side or placed above each
ether. I do not bind myself to carry out my invention exactly as shown in the
drawings as the form and design must be altered to suit the position in which the
apparatus is situated.
In order that my invention may be fully and clearly under-
stood and carried into practical effect as herein before described I have annexed to
this Specification the accompanying four sheets of drawings and now refer to the
figures and letters of reference marked thereon.

inlet. A is the door giving access to the heating chamber of the heating apparatus.

Having now particularly described & ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination as described of an illuminating chamber in front off, at the
side, or above a heating & ventilating apparatus & constructed to prevent the
flame & products of combustion from mixing with the atmosphere of the interior
of the building or other chamber's in which the apparatus is fixed and all substan-
tially as set forth.
2. The combination of illuminating, ventilating and cooking apparatus constructed
to prevent the products of combustion from mixing with the inside atmosphere of
the building and with a regulated supply of air to the burners for combustion
constructed to obtain a high efficiency and all substantially as set forth.
