Improvements in Appliances for Converting an Ordinary Open Fire
Grate into a Slow Combustion Grate or Close Stove.
:
I CHARLES WHITE of 2 Chepstow Villas, Elland Road Peckham Rye London,
Gentleman, do hereby declare the nature of this invention to be as follows:-
This invention relates to open fire grates, and its object is to confer upon an
ordinary open fire grate the advantages belonging to a slow combustion grate or
close stove at will, & at trifling cost, so that those in poor circumstances may get
the benefit of such an arrangement in economy of fuel & saving of time and labour,
as well as complete control of the element, & the convenience of being able to
keep the fire alight all night without attention & draw it up again, brightly, in a
few moments in the morning; clearing out the ashes & cleaning the grate without
putting out or disturbing the fire.
First of all, then, I cover over the grating at the bottom of the firegrate, with
iron or other metal firebrick or any other substance or preparation so as to stop
the draught.
I next make a grating to fit the bottom of the fire-grate & rest upon the false
bottom, afore described: so that there is a space of half-an-inch or so (more or
less) between the two, to permit the ashes to fall through the grating on to the
false bottom & be raked out, clearing the fire at will & increasing the draught if
desired. This grating may be made of any metal, or substance, cast or wrought;
or it may be made of wire interlaced and may be either fixed or fastened to the
false bottom, or detached from it.
Then, I make a cap to hook, or otherwise fasten on, in front of this grating so
as to exclude the draught & insure slow combustion if desired; this cap may have
a small handle in the front, and can be taken off & put on in a moment, and it can
be made of any metal or substance.
I next make a shield, with handle in the centre, to hook or otherwise fasten on
to the front bar, or bars of the fire grate, so as to shut in the lower portion of the
firegrate, thus excluding all draught but such as is sufficient to keep the fire
smouldering.
Lastly, I make a blower with handle in front, which owing to its shape, will
stay up without any fastening at all, or it may have fastenings of any kind attached
to it or to the grate.
These two last may be made of any material or substance & to fit any kind or
shape of grate; & may be plain or ornamented: their handles, also, may be
protected by or made of any kind of non-conducting substance or material & may
have a small ring above the handle or elsewhere to enable them to be lifted off with
a hook if they have been allowed to get too hot.
When these are together in position in conjunction with the other appliances the
whole fire grate is completely closed in & resembles a close stove.
Dated this Twenty-eighth day of November 1895.

Improvements in Appliances for Converting an Ordinary Open Fire
Grate into a Slow Combustion Grate or Close Stove.
I, CHARLES WHITE No. 2 Chepstow Villas Elland Road Peckham Rye
Gentleman 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 :-
•
This invention relates to improvements in appliances for converting an ordinary
open fire grate into a slow combustion or closed stove and the same is carried out
as follows.
Referring to the annexed drawings
Figure 1 plan view of plate for lying on the ordinary bottom of the fire grate.
Figure 2 plan view of a perforated grating having projections or feet for 1
resting upon the plate shown in Figure 1.
Figure 3 plan view of curved plate in Figure 4.
Figure 4 curved plate for closing front fire bars.
Figure 5 front view of blower plate.
Figure 6 front view of grate showing my invention in position.
Figure 7 front view of plate and perforated grating.
Figure 8 plan view of plate for closing aperture or space between grating or
perforated plate a and plate c.
Figure 9 front elevation of same.
Referring to Figures 1, 2, and 7, a is a perforated grating having feet b which
rest upon the plate c which is placed on the bottom of an ordinary grate.
Referring to Figures 3 and 4 d is a plate having a handle e and hooks for a centre
hook for attaching the plate to the front bar or bars of the grate; said plate d
being curved so as to correspond with the curvature of the fire bars to which it is
attached.
Referring to Figure 5 g is a plate or blower having a handle for closing the
opening between the top of the fire bars and grate opening said plate g having
suitable aperture i closed by shutters so that the draught may be regulated, the
plate g being bent or shaped to suit the opening to be closed.
Figure 6 shows my invention in position.
By the use of the plate c & grating a a space is left for the ashes to be raked
out & by the use of the curved plate d air may be prevented from entering the fire
through the front bars. The plate on blower g having the apertures as shown by
the dotted lines. i is employed to regulate the draught.
Referring to Figures 8 and 9 j is a bent strip or plate of metal having the handle or
knob for closing the space between the perforated grating a and plate c, K. being a
hook for engaging on the grating a so as to maintain the strip or plate j in position.
This plate or strip; prevents the direct draught of air passing through the grating a.
Having now particularly described and 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. In means for converting open fire grates into slow combustion or close stoves;
in combination the various parts herein shown and described.
Dated this 5th day of February 1896.
CHARLES WHITE.
