We THOMAS WATSON and THOMAS PARKIN MOORWOOD, of the Harleston Iron
Works, Harleston Street, Sheffield, in the County of York, Engineers, Ironfounders,
and Stove grate Manufacturers, do hereby declare the nature of our Invention for
IMPROVEMENTS IN CANOPIED STOVE GRATES, AND FIRE PLACES, AND IN APPARATUS
AND APPLIANCES CONNECTED THEREWITH to be as follows:-
The object of our Invention is to provide increased facilities for sweeping the
chimney or flues, and likewise means of regulating the draughts or currents of air
passing through stove grates and fire places which are fitted with canopies or curtains,
and consists in fitting the canopied or curiained portions of such stove grates and fire
places with movable louvres or venetians, hereinafter called louvres, so that one or
more, or all of such louvres, may be opened, closed, or taken out at pleasure, the
louvres themselves being arranged to work on pins or pivots in racks or other suitable
bearings in a similar manner to that at present employed where louvres are fitted in
the backs of stove grates and fire places. The louvre bars may be made to extend
across the whole width of the canopy, or two or more widths may be employed, and
they may be made to work separately, or simultaneously, or otherwise as required.
The outer surface of such louvre bars may be ornamented or otherwise so that when
they are all closed they may have the appearance of forming part or parts of a close
canopy.
The action of our improved appliance or appliances is as follows, what may be called
the normal condition, would be with the whole of the louvre bars closed, under which
condition the stove grate or fire place would act in a similar manner to any other

page_text: canopied or curtained stove grate or fire place of the same size and proportions.
When the chimney or flues require sweeping, the whole or any number of the louvre
bars may be removed, thus giving increased facility for the operation to be performed;
and when the stove is in use, by opening the louvre bars the draught or currents of
air passing through the fire may be decreased, and the intensity of the fire thereby
diminished; and in like manner when the grate is only used for ventilating purposes,
a larger amount of air may be passed through the openings into the flue than would
he the case with an ordinary canopied stove grate or fire place.

IMPROVEMENTS IN CANOPIED STOVE GRATES, AND FIRE PLACES, AND IN APPARATUS

performed to be particularly described and ascertained in and by the following
statement:-

The object of our Invention is to provide increased facilities for sweeping the
chimney flues, and likewise means of regulating the draughts or currents of air
passing through stove grates and fire places which are fitted with canopies or curtains,
and consists in fitting the canopied or curtained portions of such stove grates and fire

or all of such louvres may be opened, closed, or taken out at pleasure, the louvres
themselves being arranged to work on pins or pivots in racks or other suitable bearings
in a similar manner to that at present einployed where louvres are fitted in the backs
of stove grates and fire places, the louvre bars may be made to extend across the
whole width of the canopy or two or more widths may be employed, and they may be
made to work separately or simultaneously or otherwise as required.
The outer surface of such louvre bars may be ornamented or otherwise so that when
they are all closed they may have the appearance of forming part or parts of a close
canopy.
The action of our improved appliance or appliances is as follows, what may be called
the normal condition would be with the whole of the louvre bars closed, under which
condition the stove grate or fire place would act in a similar manner to any other
canopied or curtained stove grate or fire place of the same size and proportions.
When the chimney or flues require sweeping, the whole or any number of the
louvre bars may be removed, thus giving increased facility for the operation to be
performed; and when the stove is in use by opening the louvre bars the draught or
currents of air passing through the fire may be decreased and the intensity of the fire
thereby diminished; and in like manner when the grate is only used for ventilating
purposes a larger amount of air may be passed through the openings into the flue
than would be the case with an ordinary canopied stove grate or fire place.
The nature of my Invention will be better understood on reference to the accom-
panying sheet of drawings in which,
Fig. 1-is a front elevation in perspective of what is technically called the interior
of a stove grate, fitted with our improved louvred canopy the louvres being
closed.

Fig. 4 is a cross section shewing the canopy rack or bracket with the louvres
removed.
Fig. 5 being one of the louvres detached from the canopy.
The same letters refer to similar parts throughout the several views.
a is the louvre or louvres.
,b, are the pins or pivots of the same.
e, c, the enlarged end of the pins or pivots by which they may be opened, closed or
otherwise adjusted or by means of which they may be lifted out of the bearings in the
racks or brackets.
d, is the rack or bracket and
e, e, e, are the bearings for the louvre pins or pivots.
ff, are small pins or stops to prevent the louvres being turned too far in either
opening or closing.
Having now particularly described and ascertained the nature of our Inven-
tion and in what manner the same is to be performed we declare that what we
claim is,
(1) The arrangement and combination of parts by which the canopied or curtained
portions of stove grates, and fire places are constructed with movable louvres or
venetians so that one or more or all of such louvres or venetians may be opened, closed,
or otherwise adjusted or taken out, substantially as and for the purposes hereinbefore
described.
(2) Improvements in canopied stove grates and fire places and in apparatus and
appliances connected therewith, substantially as herein before described and illustrated
in the accompanying drawings.
