PROVISIONAL SPECIFICATION.
Improvements in and applicable to Fire Places or Grates.
I, CHARLES MARSHALL the younger, of 5 Clarence Street, Cheltenham, in
the County of Gloucester, Ironmonger, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the construction and application to fire places and
grates of a perforated or open receptacle or basket filled with small coke, asbestos
or like material whereby a more complete combustion of the fuel of the fire is
effected.
In carrying out my invention as applied, for example, to an ordinary domestic
fire place I form my basket of a size and shape that it can be fitted between the
top of the back of the fire place and the upper part or front of the stove so as to
form a kind of screen between the fuel and the flue. My basket is advantageously
filled with small coke through which the products of combustion have to pass
before they reach the flue. When the fire is first lighted the unconsumed carbon
from the combustion of the fuel is deposited on the coke in the basket which coke
gradually becomes heated to incandescence consuming or partly consuming the
products of combustion already deposited thereon as also those which continue to
pass through.
By this arrangement not only is a more perfect combustion of the fuel effected
than hitherto and the formation of smoke practically prevented but my basket acts
as a radiator of the heat into the room.
In practice I provide between the top of my basket and the front of the stove or
the canopy thereof a register to allow of any excess of the products of combustion
(over that which passes through the basket) passing to the flue and also to allow of
the admission of air to the flue when required.
The basket is made removable for the purpose of cleaning and refilling.
Although I have described the use of a basket filled with coke or asbestos it is
to be understood that in some cases I can employ other materials such as woven or
coiled wire.
COMPLETE SPECIFICATION.
Improvements in and applicable to Fire Places or Grates.
I, CHARLES MARSHALL the younger, of 5, Clarence Street, Cheltenham, in
the County of Gloucester, Ironmonger, do hereby declare the nature of this
5 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 the construction and application to fire-places and
grates of a perforated open receptacle or basket filled with small coke, asbestos or
like material and so arranged that it will be heated by the fire whereby a more
O complete combustion of the fuel of the fire is effected than heretofore.

page_text: To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a front elevation of a fire-place or grate having my improvements
applied thereto :
Figure 2 is a vertical section. of the same; and,
Figure 3 is an elevation of the open receptacle or basket detached.
as
In adapting my invention to an ordinary domestic fire-place such for example
that shewn in the drawing I provide the back of the grate with a ledge or shelf a
and I form my basket (indicated by the letter b) of a size and shape that when
resting upon the shelf a its upper part will lie against the front of the stove as at c
and fit between the grate sides d, d so as to form a kind of screen between the fuel
and the flue e. As hereinbefore stated my basket is advantageously filled with
small coke through which the products of combustion have to pass before they
reach the flue. When the fire is first lighted the unconsumed carbon from the
combustion of the fuel is deposited on the coke in the basket, which coke gradually
becomes heated to incandescence, consuming or partly consuming the products of
combustion already deposited thereon as also those which continue to pass through.
By this arrangement not only is a more perfect combustion of the fuel effected
than hitherto and the formation of smoke practically prevented but my basket acts
as a radiator of heat into the room.
In practice I provide between the top of my basket and the front of the stove.or
the canopy thereof a register f to allow of any excess of the products of combustion
(over that which passes through the basket) passing to the flue e and also to allow
of the admission of air to the flue when required.
In order to allow of recharging the basket I advantageously provide the front or
canopy of the stove with a door g which will turn down, and to prevent the intro-
duction of coke or the like into the V-shaped space behind the basket I prefer to
form the latter with an upward extension constituting a kind of hopper.
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 :-
:―
1. The combination with a fire-place or grate of a perforated or open receptacle
or basket filled with small coke, asbestos or the like, substantially as, and for the
purpose, described.
2. A fire-place or grate having a basket or receptacle applied thereto, sub-
stantially as herein before described and illustrated in the accompanying drawing.
3. In a fire-place or grate having a receptacle or basket applied thereto as
described, a register such as fand a door such as 9 substantially as, and for the
purposes, described.
