PROVISIONAL SPECIFICATION.
Improvements in Cinder Sifters.
I GEORGE JOHN BOLINGBROKE of Western Villa Chelmsford in the County of
Essex Draper do hereby declare the nature of this invention to be as follows:-
The invention has for its object the construction of a cinder sifter for domestic use,
in which the dust caused by the sifting does not escape into the room.
According to my invention a long shaped box of convenient size is provided with a
sliding sieve, which rests in slides on the sides of the box, inside it. The sliding sieve
is operated by means of a handle on the end of a rod which passes through one end of
the box. The top of the box is closed by a lid, and a sliding door allows the fine ashes
to be removed from the bottom of the box.
To operate the sifter the mixed ashes and cinders are placed in the sliding sieve, &
the lid is closed. The sieve is then worked to & fro & the fine ashes fall into the lower
part of the box. No dust escapes into the room.
When the fine dust has settled in
the box the sieve with the cinders is removed, & the fine ashes are shot out of the box
by tilting it & opening the sliding door at the end.
I have described only one form, but of course my invention may take the forms
of sifters differing considerably in details of construction.
For instance a sort of pail may be made with a lid & a movable sieve with the
bottom about half way down. The cinders & ashes are put in & the lid put on & the
whole shaken.

COMPLETE SPECIFICATION.
Improvements in Cinder Sifters.
I, GEORGE JOHN BOLINGBROKE, of Western Villa, Chelmsford, in the County of
Essex, Draper," 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 :-
My Invention has for its object the construction of a cinder sifter for domestic use,
in which the dust caused by the sifting does not escape into the room.
According to my invention I construct a long shaped box of any convenient size,
provided with sliding sieve, which rests on slides on the sides of the box, inside
the same.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawings thereof, reference being had to letters and
figures marked thereon.
Figure 1 represents the view of the cinder sifter with the cover A removed, for the
purpose of describing the interior sliding sieve C, with meshes D, worked by the
handle E, on slides G, G.
Figure 2 denotes a transverse section of the cinder sifter, and the receptacle for the
dust A'.
Figure 3, is the longitudinal section of the cinder sifter, describing the sliding door B
sliding up and down in grooves, for the purpose of removing the dust from the
chamber A¹.
The sliding sieve C is operated by
passes through one end of the box A.
sliding door B allows the fine ashes to
means of a handle on the end of a rod E which
The top of the box is closed by a lid A³, and a
be removed from the bottom of the box.

page_text: To operate the sifter the mixed ashes and cinders are placed in the sliding sieve C
and D, and the lid A2 is closed, the sieve is then worked to and fro, and the fine ashes
fall into the lower part of the box. No dust escapes into the room.
When the fine
dust has settled in the receptacle A¹, the sieve C and D with the cinders is removed
and the fine ashes are shot out of the box by tilting it and opening the sliding door B,
at the end.
I have described only one form, but of course my invention may take the form of
sifters differing considerably in details of construction.
For instance a sort of pail may be made with a lid, and a movable sieve with the
bottom about half way down. The cinders and ashes are put in and the lid put on
and the whole shaken.
The handle fixed to the cinder sifter is marked F.
Having now particularly described the nature of my said Invention, and in what
manner the same is to be performed, I declare that what I claim is :-
:
First The combination of the cinder sifter, with the box A, and the dust
receptacle A, and the sliding door B, with the sieve and D sliding on slides G, G,
to prevent the dust from the operation escaping from the box, substantially as herein
described and according to the accompanying drawings.
:
Secondly The combination of the apparatus to be made in any size or shape and
of any suitable material, substantially as herein described and according to the
accompanying drawings.
Dated this 26th day of August 1889.

Applicant.
