Year: 1884

page_text: I FREDERICK HOLYOAKE MOORE, 2 Northgate Street, Warwick, Architect do
hereby declare the nature of the said invention for "IMPROVEMENTS IN
RELATING TO FIRE GRATES STOVES AND THE LIKE" to be as follows:-
OR
This grate is designed to provide a means of entirely shutting up the fire place
when not in use without stopping ventilation by the flue.
After the fashion of a sash window one or more metal curtains are arranged
hung between parting beads by copper cords metal chains or equivalent means on
pulleys with balance weights.
These curtains when lowered quite enclose the front, and when raised are
concealed behind the upper part of the grate.
They are pierced for ventilation and provide an ornamental curtain for the grate
when closed in summer time while retaining the updraught of the chimney flue.
When the fire place is in use, the upper sash would also be available for regulating
the draught to a nicety, if required for prevention of smoke.
If it is desired to dispense with the cords and weights the curtains may be made
to fit tight or have springs rollers & and instead of the curtains as described a
flexible.curtain may be employed and wound on a roller, the ventilation openings
being if preferred arranged to be closed when the curtain is used' for a blower.
Dated this 18th day of December 1884.

page_text: I FREDERICK HOLTOAKE MOORE of 2 Northgate Street Warwick Architect 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 grate is designed to provide a means of entirely shutting up the fire place
when not in use without stopping ventilation by the flue.
After the fashion of a sash window one or more metal curtains are arranged
hung between parting beads by copper cords metal chains or equivalent means on
pulleys with balance weights, or else hung with springs to slide in grooves-the
balance weights being dispensed with.
These curtains when lowered quite enclose the front, and when raised are
concealed behind the upper part of the grate.
They are pierced for ventilation and provide an ornamental curtain for the grate
when closed in summer time while retaining the updraught of the chimney flue.
When the fire place is in use the upper sash would also be available for
regulating the draught to a nicety if required for prevention of smoke.
If it is desired to dispense with the cords and weights, the curtains may be made
to fit tight or have springs, rollers &c, and instead of the curtains as described a
flexible curtain may be employed and wound on a roller, the ventilation openings
being if preferred arranged to be closed when the curtain is used for a "blower."
In the accompanying drawings Figure 1 is a front elevation of a grate
constructed according to this invention and Figure 2 a vertical cross section of
the same.
A is the front preferably made of cast iron with ornamental tiles B the top
screen or curtain and C the lower screen which is perforated in
any suitable
manner as at C2 or made with openings which permit the passage of air when the
screen is down while the screen is sufficient to hide the opening of the fire place.
When the grate is in use the screens which slide in the grooves B and C are run
up out of the way, or the upper screen B may be brought into use as a blower to
increase the draft if desired.
:
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
The combination with a firegrate or stove of; a curtain such as C adapted to
close the grate opening and provided with ventilation openings. C whereby the
up draught of the chimney may be utilized though the grate opening be closed
substantially as specified.
Dated this 18th day of September 1885.
