PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Sifting Cinders and other
Materials.
ROBERT CADMAN Ship Fitter of No. 20 Chapelhouse Street, Millwall in the
County of Middlesex do hereby declare the nature of this invention to be as
follows:-
The object of my invention is an improved arrangement of parts whereby cinders
or other material
ma
be sifted.
For this purpose I provide a square or other shaped box fitted with a riddle or
sieve which slides in bearings in the sides of such box, I also provide a moveable
flap which forms one end of the riddle or sieve and holds the riddle or sieve in a
horizontal position for the purpose of riddling the material, the flap also turns in
bearings on the side of the box and is held in position by a catch fixed to the said
box, by releasing the flap the riddle or sieve turns and discharges the riddled
material into the receptacle provided by fixing a partition in the box I divide the
riddled material.
The box may be any shape or size to suit the surroundings and may be made
suitable for placing in any position.

Improvements in Apparatus for Sifting Cinders and other
Materials.
I, ROBERT CADMAN, of 20 Chapel House Street, Millwall, in the County of
London, Ship's Fitter, do hereby declare the nature of the said 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 improved apparatus for sifting cinders and other
materials, and consists mainly in the combination of a laterally moving riddle or
sieve, with an adjustable flap which, in the one position, serves to support the
riddle while being operated and serves to direct the ash or like refuse into a
receptacle therefor, and, in the other position, ceases to support the riddle and
permits of the latter shooting the cinders or the like into a receptacle adapted to
receive the same.
On the accompanying drawings,
Fig. 1, represents a sectional elevation of one modification of the improved
apparatus,
Fig. 2, represents a sectional plan on the line a, b, Fig. 1, and
Fig. 3, represents a sectional elevation of another modification.
In carrying out my invention, a sieve or riddle a, (preferably made with a raised
end and sides a', and with an open end a³,) is secured by nuts a³, or other suitable
means to an operating rod a', which is supported by the sides of a casing b, in
bearings. When in its riddling position, the open end of the riddle is supported
by resting on an adjustable flap c, which is normally supported in an inclined
position (vide the full lines, Fig. 1,) and then serves to close the open end of the
riddle, and to direct the ashes or the like waste which may fall therethrough onto

page_text: it, into the ash receptacle d, ride the arrows 1. The flap c, is secured by nuts c², or
the like, to a rud c, which is supported by the sides of the casing b, in bearings c³,
and is, at one end, formed with a handle, which is adapted to rest in a bracket c³,
secured to the casing, when the flap and riddle are desired to be secured in the
operative positions shown in full lines in Fig. 1. When the contents of the riddle
have been sufficiently shaken to separate the ashes from the cinders, and it is
desired to shoot, the cinders into the cinder receptacle e, the handle e, is raised
from its support c, and is laterally shifted clear of such support and is let fall or
lowered to the position indicated in dotted lines Fig. 1, (ride also Fig. 3,) whereupon,
the flap c, ceases to support the riddle which, consequently, falls to the position
also indicated in dotted lines Fig. 1 (vide also Fig. 3.) when it is arrested by a
partition and shoots its contents into the receptacle e.
The receptacles d, e, may be of any desired relative capacity, and may entirely
occupy the bottom part of the casing b, vide Figs. 1 and 2, or they may be arranged
as represented in Fig. 3, in which case the casing b, supporting the cinder
receptacle e, fits into a lower casing g, which is adapted to receive a pail or other
ash receptacle d.
In either modification, the casing 6, may be further formed with an opening h,
closed by a sliding or hinged door h, enabling potato peelings and other like
refuse to be thrown directly into the ash receptacle.
The casing b, is or may be made with a hopper-like top 63, closed by a hinged
lid 63, and its interior is or may be fitted with deflecting plates f,f', or f³, serving
to direct the cinders, ashes and refuse into their proper receptacles.
The rod a', operating the riddle may be made with a suitable handle a³, for operating
it by hand in apparatus of a size suitable for domestic use, or it may be operated by
power, in any suitable manner, in apparatus of a size suitable for manufactories or
where it may be required to be in frequent use.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
1. The combination, in apparatus for sifting cinders and other materials, of a
riddle or sieve capable of reciprocating movements for riddling its contents, and of
a turning movement about its axis for discharging its riddled contents; with a flap
adapted to support the riddle in its operative position, and to direct any ash or the
like which may fall thereonto into a receptacle therefor and to be released from
supporting the riddle so as to allow of the latter turning about its axis and dis-
charging its riddled contents into a receptacle therefor; and a stop or partition
(which may also serve as a deflecting plate) serving to arrest the riddle when
turning about its axis so as to cause it to discharge its riddled contents into the
receptacle therefor, substantially as hereinbefore described.
2. The arrangement of apparatus hereinbefore described with reference to
Figs. 1 and 2, of the accompanying drawings.
3. The arrangement of apparatus hereinbefore described with reference to Fig. 3,
of the accompanying drawings.
