Complete Specification Left, 16th Apr., 1895-Accepted, 18th May, 1895
Mrs. SARAH ANN CACKETT KATE ELIZABETH DARLOW Grange House,
Gipsy Lane Upton Park Essex, Milliners, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to an improved coal economiser for kitchen & other
grates and may be used as an ordinary false bottom & back which will effect
considerable saveing at the same time causing the fire to burn more clearly and with
very little smoke in such a manner that instead of the ordinary brick back being
placed at the back of stove to reduce the size of fire which prevents heat
drawing to boiler, our invention will answer the purpose of reducing size of fire,
and at the same time allow the heat to draw under the boiler, whereby the water
may be heated from a small as well as large fire.
In bringing our invention into practice we form an ordinary false bottom with
wide edge at back having two holes large enough to receive standards that are
made upon a portable back.
The back has two projecting pieces from the top which prevents it lying close
upon back of stove or boiler thereby causing a draught to be drawn under the
open space and will cause the fire to burn more clearly.
This device may be made in various sizes to suit all grates and of iron or
any other suitable material.
Our invention of coal economiser is found in two distinct parts the centre of
each having cross bars to allow draught.
Dated this 16th day of August 1894.

Improved Coal Economizer.
We SARAH ANN CACKETT and KATE ELIZABETH DARLOW of Grange House
Gipsy Lane Upton Park Essex 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 :-
Our invention relates to an improved coal economizer for kitchen & other
grates and may be used as an ordinary false bottom & back and which will effect
considerable saveing at the same time causing the fire to burn more clearly & with

page_text: In bringing our invention into practice we form an ordinary false bottom with

made on a portable back.
The back has a projecting piece from the top which prevents it lying close to
back of stove or boiler thereby causing a draught to be drawn under the open
space & will cause the fire to burn more clearly.
This design may be made in various sizes to suit all grates & of iron or any
other suitable material.
Having now particularly described & ascertained the nature of our said
invention & in what manner the same is to be performed we declare that what we
claim is as follows,
1st. That our false bottom differs from the ordinary one used, in that it has a
wide edge at back sufficient to allow holes a each corner to receive standard of
back.
2nd. That a back being formed with standards to fit in holes formed in bottom,
prevents either bottom or back from getting out of place in grate.
3rd. That the size of fire is greatly reduced but is brought to the front and
top of grate for use, unless needed to heat boiler quickly when damper over
boiler being drawn out the heat draws through bars or perforations of back under
boiler, thereby heating water & saving coal. And in case of being used in register
stoves the heat is thrown into room by small fire which lies at top & front of
grate only.
