PROVISIONAL SPECIFICATION.
An Improved Cinder Sifter.
THOMAS POUNDER 10 Olive Street Hartlepool Shipwright do hereby declare the
nature of this invention to be as follows:-
A metal design for domestic purposes fitting beneath the fire grate purporting to
seperate the cinders from the ashes, to bring the cinders forward & allow the ashes
to fall through. Using this invention it would only be necessary to gather the ashes
say every two to four days.
The article consists of a number of parallel bars which slope from the back of
the fire-place to a solid perpendicular front which rests on the hearth & joins the
bars at a height of about 3 & inches. As the cinders fall on to these bars they
roll to the front, & as they roll the ashes are of course sifted from them & pass
through the interstices of the bars.

COMPLETE SPECIFICATION.
An Improved Cinder Sifter.
THOMAS POUNDER 10 Olive Street Hartlepool Shipwright 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 :—
A metal design for domestic purposes fitting beneath the fire grate purporting to
seperate the cinders from the ashes, to bring the cinders forward & allow the ashes
to fall through. Using this invention it would only be necessary to gather the ashes
say every two to four days.
The article consists of a number of parallel bars, which slope from the back of
the fireplace to a solid perpendicular front, which rests on the hearth & joins the
bars at a height of about 3 & inches. As the cinders fall on to these bars, they
roll to the front, & as they roll the ashes are of course sifted from them & pass
through the interstices of the bars.
Attached is a small drawing of the invention on the scale of 3 in. to the foot,
showing 13 in. at the base.
A. B. C & D is metal & E. E. the spaces between the bars, each in. The
bars C. C. are each in. thick, therefore there are 2 bars & 2 spaces to the inch.
The bars are 9 in. long.
Section C shows the whole of the middle bars, which are
in thickness on the lower edge.
in. in depth & 1 in.
The end bars D. are 1 & in. in breadth at the lower end joining the front A,.
which is 3 & in. in depth making with the in. bars an entire depth of 34 in.
The lower edge of the front A is in. thick & the upper edge is in., between
the bars however the edge is only 1 in. thick, with a groove brought down 1 & in.
inside of A.
D. is to keep the ashes in.
B. is the connection of the whole of the bars at the upper end.
The "sifters" will of course be of various sizes to meet requirements. A larger
size will be made by simply adding more bars & spaces & a smaller one by having
fewer bars & snaces.

page_text: Having now particularly described & ascertained the nature of my said inven-
tion, & what manner the same is to be performed, I declare that what I
claim is:
(1) Saving of fuel, inasmuch as there is no waste of cinders, as they are entirely
seperated from the ashes & brought to the front, when they can be lifted up at any
time & put on the fire again.

(2) Saving of labour, since the "sifter" screens the ashes from view, it is only
necessary to remove it to clear away the ashes say every two to four days (accord-
ing to the amount of coal consumed).
(3) Tidyness, inasmuch as the hearth must at all times look cleaner when
using the invention than when not as the refuse of the fire is hid from view, & the
"sifter" itself, giving a finish to the fire grate improves the general aspect of the
hearth.
