PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Fire Grates or Stoves for
Household Use or the like purposes.
I, JOHN ROBINSON CROSTHWAITE, of The Union Foundry, Thornaby-on-Tees,
in the County of York, Ironfounder, do hereby declare the nature of this invention
to be as follows:-
This invention is intended to effect certain improvements in the construction
and arrangement of fire grates or stoves of the kind adapted for household use
or for the like purposes.
The object in view is to enable the fire grate or fuel basket to be adjustable
to a greater or less capacity according to the amount of warmth to be derived
from the fire, or in other words to enable the same stove to be used with an enlarged
fuel capacity at one time and with a diminished fuel capacity at another time at
the option of the person in control of its use.
The nature of iny invention consists as follows:-In combination with the usual
back area of the stove or fuel basket, whether in the form of a back bottom
grate or bottom brick, I provide an arrangement of front bars or breast which
is reversible and which in one position recedes inwardly from the standards, slides
or side pieces so as to keep back the fire front and so reduce the fire. The
arrangement of front bars or breast is so made or fitted to the stove front as
to slide up or unhook and when turned round back to front fits on the same
slides or hooks as before. In this reversed position it projects as far outwardly
as it receded inwardly before and the requisite accomodation is thus afforded for
a larger fire.
The increased bottom area of the fuel basket now existing between the bottom
front bar and the front or opposite edge of the back bottom brick or back
bottom grate I fill up with a loose front bottom grate which may be altogether
removeable but which is preferably hinged at the back corners and supported
in front by resting on the bottom front bar in a horizontal or slauting position
so that instead of altogether removing the said front grate to reduce the capacity
of the fuel basket it will instead swing down on its hinged supports to the
vertical or edgewise position with the back or upturned edge in line with the
fire grate level.

COMPLETE SPECIFICATION.
Improvements in or appertaining to Fire Grates or Stoves for
Household Use or the like purposes.
I, JOHN ROBINSON CROSTHWAITE, of The Union Foundry, Thornaby-on-Tees,
in the County of York, Ironfounder, do hereby declare the nature of this inventiou
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention is intended to effect certain improvements in the construction and
arrangement of fire grates or stoves of the kind adapted for household use or for

page_text: the like purposes, that is of the well known type in which an open fire is placed
upon a bottom grate or brick or part of each behind a breast or frame of
open bars.
The object in view is to enable the fire grate or fuel basket to be adjustable to a
greater or less capacity according to the amount of warmth to be derived from the
fire; or in other words to enable the same stove to be used with an enlarged fuel
capacity at one time, and with a diminished fuel capacity at another time at the
option of the person in control of its use.
And in order that my invention may be fully understood, I will now proceed to
describe the same with reference to the sheet of drawings hereto annexed, in which
I have illustrated a store embodying my invention, but which stove in other
respects is to be taken as representative of stoves generally of the kind to which
my invention is applicable.
Figure 1 is a vertical sectional view of the stove taken on line xx of Figure 2
which is a sectional view in plan taken on line of Figure 1, the two figures
together being intended to illustrate how the grate or fuel basket of the stove is
reduced in the manner hereinafter described.
Figure 3 is also a vertical sectional view of the stove taken on line y y of
Figure 4, which is a sectional view in plan taken on line y' y' of Figure 3, these
two figures together being intended to illustrate how the grate or fuel basket
of the stove is extended in the manner hereinafter described.
In combination with the usual back area of the stove or fuel basket u, whether
in the form of a back bottom grate or bottom brick I provide an arrangement or
frame of front bars or breast which is reversible and which in one position
recedes inwardly from the standards, stiles or side pieces cas shown in Figures 1
and 2 so as to keep back the fire front and so reduce the fire. The arrangement
of front bars or breast is so made or fitted to the stove front as to slide up
or unhook, and when turned round back to front fits on the same slides or hooks
as before, and in the position shown in Figures 3 and 4. In this reversed
position it projects as far outwardly as it receded inwardly before, and the
requisite accomodation is thus afforded for a larger fire. The increased bottom
area of the fuel basket now existing between the bottom front bar b' and the
front or opposite edge a¹ of the back bottom brick or back bottom grate a,
I fill up with a loose front bottom grated which may be altogether removable
but which is preferably binged at the back corners d¹ and supported in front
by resting on the bottom front bar in the manner shown in Figure 3, that is
in a horizontal or slanting position, so that instead of altogether removing the
said front grated to reduce the capacity of the fuel basket, it will instead swing
down on its hinged supports d¹ to the vertical or edgewise position as shown in
Figure 1.

But it must be understood that my invention is not to be limited to the precise
arrangement of details shown in the drawing as these can be readily varied in
certain respects without departing from the essential features thereof, for instance
the books e secured to the side pieces c and hooking into an undercut recess /
within the openings in the front bar or breast frame b, are merely intended to
show a mode of reversible attachment of the said front bar or breast frame b to the
said side pieces which is convenient for the purposes of my invention and
similarly any convenient mode of supporting the bottom front grate
substituted for the particular arrangement shown, or in some cases this bottom
may be
front grate d may be a fixed extension of the bottom back brick a.
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 :-
Firstly. In a fire grate or store of the kind in general use for household purposes,
the use of a reversible front bar or breast frame whether separately or in com-
bination with a loose front bottom grate, which front bottom grate
may be

page_text: removable or he hinged in position, the several parts being constructed, arranged
and fitted together substantially as and for the purpose as hereinbefore described
with reference to the accompanying drawings.
Secondly. A fire grate or stove of the kind in general use for household purposes,
in which a reversible frout bar or breast frame and a loose front bottom grate are
provided as a means for enlarging or diminishing the capacity of the fuel basket,.
substantially as and for the purposes as hereinbefore described and illustrated by
way of example in the accompanying drawings.
