Improvements relating to Stoves, more especially to the
Construction of the Ashpit and Ashpan.
I, DAVID NAINBY of Scunthorpe in the County of Lincoln, Ironmonger, 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:—
The object of my invention is to provide a convenient form of ashpan which will
be found most adaptable to the modern register stoves as well as other stoves or
ranges, both as an ashpan and dust receptacle, and can also be made with under-
draught apparatus for preventing smoky chimneys, and cross-draughts from the
door and windows to the fire-place.
Fig. 4 shows apparatus applied to stoves and hearths, chimney piece being much
reduced.
Fig. 3 shows plan view of grating covering flush ashpan.
I construct my apparatus as follows:-
I employ a square box or casing A, preferably tapering towards the bottom, with a
Hange B running round the top; this casing has an inlet hole C, to which is connected
a pipe running from the outer wall or from any direction found most convenient, the
casing being easily turned in any suitable direction.
An inner and smaller casing D, also square and tapering in like manner, fits
within the outer casing, this inner casing has also a flange E running round the top,
which rests on the flange on the outer box or casing. Air holes are formed in
the inner casing in front and all the way round, or any distance as may be most
desirable; these holes allow the air from the inlet pipe to pass up and through the
fire thus causing a good draught which draws the fire and carries the smoke up the
chimney thus being an effectual preventative of smoky chimneys. Lugs G may be
cast on the inner or smaller casing, under the flange, to fit against the inner edge of
the outer casing for holding one firm within the other.
The whole apparatus is let into and is flush with the hearth H, the tiles or the
like resting on the flange of the inner casing, a raised rim J, being formed on it, for
the tiles or the like to fit up to; also an ornamental grating K or the like of any
suitable design, may be placed within the raised rim, and fitting all or part way
across, through which the ashes can easily be swept thus giving the hearth a more
finished and neat appearance.
A removable ash box L having handles L' attached, fits in the bottom of the
inner casing D, into which the ashes fall, the box can be withdrawn and emptied
when required, the tapered casing allowing of its easy withdrawal.
In cases where chimneys do not smoke the outer casing A may be dispensed with,
and the inner casing D used (with or without holes), also the box L for ash and the
grating K or the like may be used as an ashpan only the whole having a neat
appearance, the grating alone showing at the bottom of the stove, the hearth
covering the remainder of pan.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved construction of combined flush ashpan and apparatus for
preventing smoky chimneys, having outer casing A, with inlet pipe C, inner
casing D, with airholes F, grating K, and removable box L, for receiving ashes
substantially as shown and described.
2. Improved flush ashpan consisting of casing D (with or without holes F,)
grating K, removable ash receiver or box L, substantially as shown and described.
