I SAMUEL WOODY of Cleverton in the parish of Lea and Cleverton in the County
of Wilts, Gentleman do hereby declare the nature of my invention for SIFTING
CINDERS OR ASHES to be as follows:
No. 1. Cylinder with scoop-shaped front with lid or cover, double or single bottom
with space between, parallel opening or slot in side with stopper, keyed for opening
and removal, two handles-one fixed one swivelled. Bearings inside of Cylinder to
receive No. 2.
No. 2. Perforated Cylinder for insertion in No. 1. A parallel raised or projecting
scraper outside, parallel fixed divider inside. Shaft fixed through centre with pivots,
a cranked removable handle to turn revolving screen when fixed in No. 1.
No. 3. A platform bed or socket for receiving Nos. 1 and 2 with or without Ash
receiving box.

page_text: 1 SAMUEL WOODY of Cleverton, Wiltshire, 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 :-
This invention relates to a fire and dust proof apparatus for sifting cinders or ashes,
capable of being used in combination or not, with an ash receiving box or bin whereby
the operation of sifting is performed in a more effectual expeditious and cleanly
manner than by the apparatus heretofore employed for that purpose.
cinder or ash sifter according to my invention consists of a metal cylinder
formed with a scoop shaped front at one end and provided with an internal hinged
semicircular flap-lid or cover capable of closing or opening either half of the cylinder
according to the position in which the lid is placed. The opposite end of this cylinder
is provided with a single or a double closed bottom with air space between to avoid
overheating of the outer bottom by the cinders. An oblong opening or slot is made
along one side of the cylinder which opening is closed by a removeable lid or cover.
Two handles are also fitted to the cylinder near the opposite ends thereof the one
being fixed and the other hinged as in an ordinary coal scuttle. Inside the said
cylinder there is introduced a perforated sheet metal or open wire work cylindrical
screen mounted on a central spindle rotating in bearings in the cylinder. This screen
carries on its outer side a longitudinal projecting rib or scraper and an internal
longitudinal blade serving as a separator or agitator of the cinders contained inside
the screen as it revolves. A removeable crank handle inserted through an opening in
the closed end of the cylinder and engaging with the corresponding end of the spindle
serves to impart the requisite rotary motion to the same.
In using the said cinder sifter the cylinder with its internal screen is stood on end
and the oblong opening in the side thereof is closed by its lid or cover-plate. The
hinged or flap lid is so turned as to leave an open mouth for the introduction of the
cinders into the screen and when charged the whole is placed horizontally in a suitable
cradle or holder on a platform or stand which may form the removeable lid or cover
of a box or bin for the reception of the ashes or siftings. The cylinder is so placed in
its support that its oblong opening shall be directly over a corresponding hopper or
mouth in the platform opening directly into the ash box. The cover plate of the oblong
opening in the underside of the cylinder is removed, and the screen is rotated by the
crank handle which is engaged with the end of the central spindle. As the screen
revolves the ashes and dust fall through it into the cylinder and the outside scraper as
it revolves draws them over the lateral opening whence they fall into the box or bin
through the corresponding mouth or hopper in the removeable lid or cover thereof.
A swivel or hinged handle fitted so as to fold inside the box is provided to enable it
to be readily carried away after the lid or platform has been removed. Whilst the
screen is in action the lower half of the open mouth of the cylinder is closed by
the flap-lid so as to prevent the escape of the screened cinders through the end of
the screen.

internal longitudinal blade or agitator.

and turns in a central bearing in an arm fixed across the open mouth of the cylinder.
I have not considered it necessary to show these bearings in my drawings as their
positions and mode of fitting will be readily understood without illustration.

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 :-
1. In a sifting apparatus the combination of a portable cylinder having a lateral
longitudinal opening and an internal flap or pivotted half lid or cover, with an internal
rotary screen carrying an external scraper and an internal agitator and actuated by a
removeable crank handle substantially as specified.
2. The combined use of the aforesaid cylinder and rotary screen with a stand
or platform provided with supports for the cylinder and a longitudinal opening
corresponding to the lateral opening in the said cylinder as and for the purpose
specified.
3. The combination of the aforesaid stand or platform with a portable box or bin
for receiving the ashes or siftings direct from the cylinder as specified.
4. The combination of a removeable cover plate with the lateral longitudinal
opening in the cylinder as and for the purpose specified.
