Improvements in Cinder Sifters.
I, ARTHUR AUGUSTUS WYNNE-JONES, Llanbedr Rectory, Ruthin, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to cinder sifters and consists in providing a box or outer
casing in which slides horizontally the riddle or sieve contained in & pivoted to a
frame; the pivoting rod protruding through each end of said outer casing or box,
where the motion is imparted. Attached to the side of the box below the sieve is
an inclined plane, the bottom half of which is hinged to an upright partition
dividing the dust from the cinders; the upper end of this bottom half is attached
to the more remote end of the sieve, so that when the latter is tilted for the
emptying of its contents the said bottom half of inclined plane will open & allow
the cinders to fall into their proper division.
The bottom half of inclined plane is controlled by a spring, for returning same
to its initial position, simultaneously with the sieve.
The box or outer casing has a lid for closing same when not in use.

Improvements in Cinder Sifters.
I, ARTHUR AUGUSTUS WYNNE-JONES, Llanbedr Rectory Ruthin North
Wales, Engineer, 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 cinder sifters and consists in providing a box or outer
casing in which slides horizontally the riddle or sieve contained in and pivoted to
a frame; the pivoting rod protruding through each end of said outer casing or
box where the motion is imparted. Attached to the side of the box below the
sieve is an inclined plane the bottom half of which is pivoted to an upright
partition dividing the dust from the cinders, the upright part of this bottom half
is attached to the more remote end of the sieve so that when the latter is tilted
for the emptying of its contents the said bottom half of inclined plane will open
and allow the cinders to fall into their proper division. The bottom half of
inclined plane is controlled by a spring for returning same to its initial position
simultaneously with the sieve. The box or outer casing has a lid for closing
same when not in use.
In order that my invention may be fully understood I now refer to the annexed
drawings in which :
Figure 1. is a side elevation in section of my invention.
Figure 2. plan view of same.

is a partition which divides the outer casing or box into two compartments, one
for ash and the other for the cinders after sifting. h is a hinged lid attached by
the chain i to the riddle or sieve at j and hinged at k to the partition g, which
closes in the space l, in conjunction with the fixed partition m. n, is a spring
which tends to keep the lid closed. This lid and fixed partition m are set at
such an angle as will ensure the dust or ash being deposited in the space 11.
After the cinders or material to be sifted has been placed in the riddle or
sieve b, the same is given a to & fro motion in the direction of the arrows 1, and
the ash falls into the space l'; the riddle or sieve is then rotated or tipped by the
spindle c, as shown by the dotted lines b', thus raising the hinged lid and allowing
the contents of the sieve or riddle to fall into the space l, and by returning the
riddle or sieve to its initial position the hinged lid is again closed by the action
of the spring n to its closed position.
The contents of the spaces and may be removed through suitable apertures
or openings in the outer casing or box, or movable receptacles may be placed in
said spaces.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combined cinder sifter and movable riddle or sieve substantially as
described and illustrated herein.
2. In cinder sifters in combination therewith a movable tipping riddle or sieve
carried upon a spindle which passes through a frame. which slides upon bearers
through the medium of rollers or wheels attached to said frame, compartments or
spaces for the reception of the sieved or riddled substance or substances, one of
the said spaces or compartments being covered or closed by a hinged inclined lid
or cover, which is controlled by a spring and connected to the sieve or riddle by a
chain or the like.
