Improvements in Fire Grates and Chimney Flues for Dwelling
Houses and other purposes.
I, ALFRED HIGGS of 123 Minto Street Ashton-under-Lyne, in the County of
Lancaster, Builder do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the construction of fire grates or ranges
and chimney flues as applied to and used for dwelling houses and other purposes.
The objects of my invention are :—
To effect economy in the consumption of fuel,
Increase the heating capabilities of the fire grate or range,
Reduce the cost and improve the construction of fire grate or range fixtures or
fittings and brickwork in connection therewith.
In my arrangement I preferably combine two fire grates (situated in separate
rooms) back to back, using one main uptake flue and other flues and chambers to act
or do duty for both grate fixtures or fittings, each grate may also be used separately
or the two may be used in combination, and one or all the rooms may be heated by
the use of one or both grates acting through the hot air-flues or chambers connected
therewith.
In conjunction with the three accompanying drawings Figs. 1, 2 and 3, I more
particularly describe my invention as follows:-
Fig. 1 shows the sectional plan of an ordinary fire grate through R. S. in Fig. 3;
Fig. 2 is a sectional side elevation through T. U. in Figs. 1 and 3; and Fig. 3 is a
sectional front elevation through V. W. in Fig. 2.

If it is required to heat range A² from the fire contained in fire grate A',-close
hinge door G and open hinge door B', thus allowing the heated gases to pass along
flue B, thro' flues F¹ and then into chimney F.
The heated gases also from range A² may be passed along flue B, by closing
dampers connected with range flues F¹, and opening doors B' and G thereby causing
the heated gases to pass to range A' and then into chimney F.
The warming of upper or other rooms is done by heated air in the following
manner: The cold fresh air supply from street by way of flue D³, passes into
chamber C, and flue E, in which Hue and chamber it is heated, and then passes-as
indicated by arrows-to the various rooms where it is admitted or excluded by

page_text: suitable dampers provided and placed near or at the termination of flues E in the
various rooms, the chamber C is formed with an inner iron casing to prevent any
escape of smoke into the hot air flues from the fire grates or ranges, the damper h
closes hot air flue E when not in use for heating purposes. Used air is extracted
from rooms by flue D which also is provided with suitable dampers in each room,
the passage of extracted air is shown by arrows in flue D.
-
In summer weather the extract flue D may be used as a fresh air supply to upper
rooms, fresh air from the street coming direct from flue D2 and passing up into
rooms above as shown by dotted arrows, in this arrangement the damper h is closed
and each room is provided and fitted with suitable outlets in or near the ceiling.

Improvements in Fire Grates and Chimney Flues for Dwelling
Houses and other purposes.
1, ALFRED HIGGS, of Needwood Terrace, Minto Street (late of 123 Minto Street)
Ashton-under-Lyne, in the County of Lancaster 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 :-
My invention relates to improvements, in the construction of fireplaces and
chimney flues, as applied to, and used for dwelling houses and other purposes.
The objects of my invention are,
To effect economy in the consumption of fuel,
Increase the heating capabilities of the fire grate, or range,
Reduce the cost and improve the construction of fireplaces and brickwork in
connection therewith.
In my arrangement, I preferably combine two fire grates, (one open fire grate for
the sitting or front room, the other an enclosed cooking range for kitchen or back
room these I set back to back in a opening specially provided, using one main uptake
smoke flue for both grates, fixtures, or fittings.
Each grate may be used seperately or the two may be used in combination, the
flues being adapted for this purpose, and one or all the rooms may be heated by the
use of one or both grates, acting through the hot air flues or chambers connected
therewith.
In conjunction with the three accompanying drawings (Fig. 1, 2 and 3) I more
particularly describe my invention as follows."
(Fig. 1) shows the sectional plan of a fireplace through R. S. in (Fig. 3).
Fig. 2 is a sectional side elevation through T. U. (Figs. 1 and 3).
Fig. 3 is a sectional front elevation through V. W. (in Figs. 1 and 2).
A¹ (Fig. 1 and 2) is a open firegrate (in sitting room). A³ is an enclosed cooking
range in the adjoining room.
B, Figs. 2 and 3, connecting passage or flue between grates A¹ and A' this passage
or flue is provided, with door or lid B₁ to open or shut, (when open) both grates
are connected and brought into use by the aid of one fire, the same fire being
utilised for warming the various rooms above.
C. hot air chamber provided with cast iron plates built in brickwork as shown
in Fig. 3.
D. ventilating or extract flue for extracting cold air from rooms above, conveying
same to hot air chamber to be warmed.
D' Figs. (2 and 3) is a flue constructed under the floor, to admit external air to
air flues from street.

page_text: In warm weather a currant of fresh air may be passed through all the rooms from
the air flues.
E hot air flues to heat upper rooms, provided with dampers to admit or exclude
the hot air.
F. main uptake smoke flue. G. binged door to main smoke flue. F¹ flues for
heating oven and boiler. H. oven. J. boiler. When the firegrate A¹ is required
only to be used, the lid or door B¹ is operated, and the connecting passage B. closed,
hinged door G. raised, thus opening a passage for the gases direct into uptake flue
or chimney F. With B' and G, in the position just described a fire may also be
placed in cooking range A². This shows the method of employing either one or
both (grate and range).
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is.
(1.) A compound, or single grate, range, stove, or fireplace, fittings and brickwork
constructed as herein described, and by which one or more rooms may be heated
from one fire.
(2.) The method of ventilating one or more rooms by flues or passages as shown
constructed and described herein.
(3.) The arrangment of the grates, dampers, passages, and flues, as described
herein, for the purposes named, and as applied to dwelling houses and for other
purposes.
Dated this 8th day of November 1894.
ALFRED HIGGS.
