PROVISIONAL SPECIFICATION.
An Improved Apparatus for Cinder Sifting or Screening and for the
like purposes.
We, THOMAS DUMERTON AND JAMES ROBERT LILLEY, trading as Dumertou
& Lilley, of Thorpe Cycle and Engineering Works, Thorpe-le-Soken, in the
County of Essex, Engineers, do hereby declare the nature of this invention to
be as follows:-
This invention relates to the above-named purpose or purposes and refers to a
self dust containing apparatus, consisting of a frame or container of any con-
venient shape and size preferably made of galvanized iron, an inlet is provided
with a cover at the top of same for the reception of ashes or the like, an inclined
screen preferably made of wires drawn tightly upon an iron or other framework
is situated within the container or box. A slide or shutter is arranged over
the screen and under the mouth of the inlet to make the apparatus dust proof,
so that dust cannot rise. The lower end of the screen rests upon or is connected
with a shoot," or enclosed drawer, which projects from the container, and
beneath the screen, and at the base of the container is a drawer.
"
When the ashes or other material to be sifted or screened are thrown into the
inlet, and the cover closed and the slide drawn out, the ashes or other material
fall upon the' inclined screen, the cinders or coarser material travel down the
screen into the shoot and thence into the box or other receptacle placed beneath
the mouth of the shoot, whilst the dust or finer stuff falls through the screen
into the drawer provided for same, for removal.
By thus arranging our apparatus in manner described, effective means are
provided which renders the action automatic and dust-proof.

An Improved Apparatus for Cinder Sifting or Screening and for the
like purposes,
We, THOMAS DUMERTON AND JAMES ROBERT LILLEY, trading as Dumerton
and Lilley, of Thorpe Cycle and Engineering Works, Thorpe le Soken, in the
County of Essex, Engineers, 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 reference being had to the draw-
ings hereunto annexed and to the figures and letters represented thereon:-

Our present invention relates to an improved apparatus for cinder sifting or
screening and for the like purposes and refers to a self dust containing apparatus
consisting firstly of a frame or container A of any convenient shape such as
illustrated and of a size to suit circumstances and preferably constructed of gal-
vanized iron or wood.
A hopper B with inlet and cover is provided at the top of the container A for
the reception of the ashes cinders or the like, and an inclined screen C preferably
made of wires C₁ drawn and stretched tightly upon an iron-or other frame C² and
parallel with the inclined sides of the framework is arranged within the container
or box A. A slide or shutter 1) is situated at the base of the hopper B under
the inlet thereinto and above the inclined screen C in order to make the apparatus
dustproof so that it cannot rise when the sifting or screening operation is pro-
ceeding.
The lower end of the inclined screen C rests upon or is connected with a
"shoot" E which projects from the container or box A near to or at its base, or
else is in connection with an enclosed drawer beneath the inclined screen Cat
the bottom of the container A.
When the ashes or other material to be sifted or screened are thrown into
the hopper or receiver B and the cover B closed and the slide or shutter D
drawn out the ashes or other material fall upon the inclined screen C the cinders
or coarser material travel down the screen Û into the shoot E and thence into a
box or other receptacle placed beneath the mouth of the shoot E for conveying
it away whilst the dust or finer stuff falls through the screen C and is received
in the drawer F provided for same for removal. After the material is thrown
into the hopper B and the slide D drawn out to allow the ashes &c. to fall on to
the screen the slide D is then pushed in to prevent the dust from rising.
By thus arranging our apparatus in the manner described and illustrated
effective means are provided whereby the action is rendered automatic and dust
proof.
For smaller sizes of sifters or for other purposes we may sometimes prefer
to dispense with the slide or shutter D at the base of the hopper A, we may
also vary the general construction and shape of the article to suit different re-
quirements without in any way departing from the principle of our invention.
Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed, we declare that what we
claim is:-
Firstly. In an apparatus for cinder sifting or screening and for the like pur-
poses the combination of the various parts and their construction consisting
of a container A with hopper B and inclined screen C and slide or shutter D) the
shoot E and drawer F all constructed arranged and operating substantially in
manner as herein more fully set forth described and illustrated.
Secondly. An arrangement of apparatus for cinder sifting or screening and
the like constructed and arranged as and for the purpose or purposes herein
set forth.
