I ARTHUR SCHELFF of 111 South Street Greenwich, Wire Worker do hereby
declare the nature of the said invention for AN IMPROVED AND COMBINED CINDER
SIFTER AND DUST BIN to be as follows:-
The object of my invention is to separate cinders or fine coal from dust, and so
prevent waste, by a simple and efficacious method, the apparatus for effecting which is
self acting.
The bin consists of a square, or other shaped box of metal or wood, or a combination
of both, and is composed of two parts or chambers fitting one upon the other by any
convenient method each having a separate bottom.
In the interior of the upper compartment or chamber is an inclined screen or sifter,
sloping from the rear towards the front of the bin, but not touching it at this part, and
attached to the lower end of the screen is an inclined plane or shoot, at a right angle
with the screen or sifter, and sloping in an inverse sense to it, that is to say from front
to rear: the object of which arrangement is as follows:-
On raising the lid of the bin (which may be hinged or otherwise connected to it)
the cinders, dust and so forth are thrown onto the inclined screen, the cinders then
fall from it onto the floor of the chamber, and the dust and grit passing through the
sifter or screen drop onto the shoot, thence to the floor in the rear, passing through
an aperture in the floor at this part into a movable receptacle or dust box, situated in
the lower chamber.
When the dust is removed, the upper chamber is lifted from the lower one, and the
dust receptacle is then accessible and can be taken out, and its contents thrown into
the cart.
Just above the floor of the upper chamber is a hinged door to give access to the
sifted cinder which can be cleared out when desired for burning.
At the upper part of the lower chamber is a movable flap, for the convenience of
throwing kitchen waste and so forth into this chamber, a door at the bottom facilitates
its clearance when required.

page_text: In lieu of the dust box being situated as above described in the lower chamber, it
may be separate from the bin and at its rear ; in this case the-shoot would be made to
project slightly beyond the back of the bin, through an opening for this purpose, and
would enter the dust box, so that the dust would pass directly into it, this box can be at
any time removed and conveyed with its contents direct to the cart without the
necessity of lifting the upper from the lower chamber.
In larger sized bins there would be no need for the floor separating the two
chambers in this case the cinders would fall direct to the bottom of the bin, the ashes
falling into an ash bin attached to the rear, that could be removed and carried to
the dust cart.

I ARTHUR SCHELFF of 111, South Street, Greenwich, Wire Worker do hereby
declare the nature of the said invention for AN IMPROVED AND COMBINED CINDER
SIFTER AND DUST BIN 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 separate cinders or fine coal from dust and so
prevent waste, by a simple and efficacious method, the apparatus for effecting which is
self acting.
In the accompanying drawings an apparatus of the description embodying my
invention is shown, minus one of its sides for showing the internal construction.
The bin consists of a square or other shaped box A of metal or wood or a combination
of both, it is composed of two parts or chambers B and C, fitting one on the other by
any convenient method, each having a separate bottom E, F.
In the interior of the upper chamber B is an inclined screen or sifter F sloping from
the rear of the bin towards the front but not touching it, the lower end of this sifter
being from 3 to 4 inches from this part of the bin.
At the upper part of the bin is a kind of hopper H where the dust and cinders are
thrown in, these then drop onto the inclined sifter F and the cinders not being small
enough to pass through the sifter fall on the bottom E of the upper chamber B, whilst
the dust and grit dropping through the sifter fall into the lower chamber C on its
floor F. The shoot at its lower end being 3 or 4 inches distant from the back of the
bin. Or the floor E of the chamber B may be continued so as to be fixed to the back
of the bin, in this case the shoot would be prolonged and pass out through a slit made
in the back of the bin and the dust and grit would pass through this opening and fall
into a receptacle for catching it, placed outside.
When the dust is removed the upper is lifted from the lower chamber, and when
there is a receptacle for catching the dust it is taken out and carried to the dust cart,
and when no such receptacle is used, then in this case the lower chamber C which
forms the dust receptacle is bodily conveyed to the cart.
Just above the floor of the upper chamber B is a hinged door I for giving access to
the interior for removing the cinders and fine coal for consumption.
Inside this door is a metal or other shield consisting of a hinged plate or strip of
metal J the hinges being about 1 inches inside the chamber. B, on its floor, this plate
has two sides K, connected to it, its object being to check the cinders or fine coal
getting into the entrance of the door or its hinges and preventing its closing.
At the upper part of the lower chamber C is a hinged flap L, for the convenience of
throwing kitchen waste and so forth into this chamber.
In larger sized bins there would be no need for the floor separating the two
chambers, in this case the cinders would fall direct to the bottom of the bin, the ashes
falling from the shoot into an ash bin attached to the rear as previously described, this
can then be removed and carried to the dust cart.

page_text: The inclined sifter, shoot and floor can also be applied to brick dust bins, in this
case doors would be fitted to the bins to give access to the chambers and for removal
of the dust &c.
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
1st. A self acting cinder and dust sifter, consisting of a box A, having two
chambers B, and C, with floors E, F, to each; with hopper H, for throwing in the
cinders dust, and so forth, an inclined screen F, and shoot G, connected one with the
other, with door 1, shield J, and flap L, the whole as, and for the purposes herein
before described.
2nd. The construction of such bins, with a lengthened shoot for passing out through
an aperture in the back of the bin, to conduct the dust and grit to a dust box outside
as herein explained.
3rd The application of this system to brick hins
