PROVISIONAL SPECIFICATION.
Improvements in or relating to Means or Apparatus for Sifting or
Screening Cinders and Ashes.
I, JOHN SQUIRE, of 34 Wellington Road, Ilkley, in the County of York, Joiner
do hereby declare the nature of this invention to be as follows:-
This invention relates to means or apparatus for sifting or screening ashes so as
to remove all dust and useless substances from the cinders prior to their being
reused, and also to prevent the dust from rising into the room or atmosphere during
the sifting or screening process.
According to this invention, within a suitable box or other receptacle, removeable
or otherwise, (provided with one or more doors or lids for the admission and
removal of the ashes and cinders) of any suitable size and shape is mounted in
bearings (either within the box or receptacle, or formed on or attached to its sides)
an oscillating trough into which the ashes and cinders are first placed. This ash
receiving trough is preferably, though not necessarily so, made with a semi-circular
wire worked bottom which is attached to end pieces. To the end pieces are fixed
or attached trunnions in such a manner that after the sifting operation has been
performed the trough, containing cinders only, may be detached therefrom or the
trunnions (and trough) removed from their bearings to permit of the trough being
removed from the box or other receptacle.
The end of one or both trunnions may be arranged to project through the sides
of the box or other receptacle and then bent to form a handle, or a handle may be
fixed thereon, for oscillating the trough for sifting and screening purposes.
The ash receiving trough may be mounted within the box or other receptacle
(such as an ashpit) in any desired position, and during the sifting and screening
process it is completely enclosed therein to prevent any dust rising into the room
or atmosphere.
Dated this Fifteenth day of October 1890.

COMPLETE SPECIFICATION.
Improvements in or relating to Means or Apparatus for Sifting or
Screening Cinders and Ashes.
I, JOHN SQUIRE, formerly of 34 Wellington Road, but now of 6, West View,
both in Ilkley in the County of York, Joiner, 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 means or apparatus for sifting or screening ashes, so
as to remove the dust and useless substances from the cinders prior to the latter
being reused, and also to prevent the dust from rising into the room or atmosphere
during the sifting or screening process.
In the drawings:-
Fig. 1 is an elevation with a portion of the side removed for showing the ash
receiving trough in position.
Fig. 2 is a plan looking at the top with lid of the ashbin or pit removed.
Figs. 3 and 4, are respectively a part sectional elevation and a longitudinal
section of ashbin or pit with screen in position.
Fig. 5 an elevation of ash receiving trough and means for oscillating the same.

page_text: A is a receptacle for the ashes and screen, hereafter termed the ashpit. It may
be made of wood, sheet metal or the like, or built of bricks, or other material in
any suitable shape and size.

In the drawings it is shown as a box or bin capable of being removed from place
to place, but it may also be a fixture, and built of brick or other suitable material
to form an ashpit either under an ordinary stove or out of doors.
The ashpit may be covered by simply laying on its top a lid a, or one or more
lids or doors may be jointed thereto to prevent the dust escaping into the room or
atmosphere.
Within the ashpit is mounted, at a suitable distance from its base, an oscillating
ash receiving trough or screen B (hereafter termed the screen) into which the
ashes and cinders are first placed. The screen B is preferably (though not neces-
sarily so) provided with a semi-circular wire worked (sieve like) bottom b, stretched
between and fixed to two wooden or metal end pieces 12 as shown. To the end
pieces are fixed or attached the trunnions which are respectively mounted in
the bearings 6 (fixed within the ashpit, either to one or both of its sides or at a
distance therefrom as shown) in such a manner that after the sifting operation has
been performed the screen containing the cinders may be unshipped from one or
both of its trunnions and raised from the ashpit to permit of the cinders being
removed. In the drawings the trunnions 3 is shown fixed to the end piece while
the trunnion is formed as shown at Figs. 3 and 4, to permit of the screw being
unshipped, that is to say the horizontal portion forms the trunnion proper which
works in the bearing b. The inner end is bent to form a hook which engages
with one or more eyes or loops 8 fixed to the end piece 2, while the portion is
carried outward beyond the bearing 6, and turned upward to receive a handle ¹º
by which the screw is oscillated.
In some cases and when preferred instead of mounting the screen upon trunnions,
such as described, two trunnions (like 3) may be fixed to the end pieces b¹², and a
lever (see Fig. 5) passed through the eyes or loops 8. In this case a slit or
slots requires to be provided in the lid a to permit of the lever working to and fro.
Or a handle and trunnion similar to that shown at Figs. 3 and 4 may be fixed to
the end piece 3 in which case a vertical slit or slot (extending from the upper edge
of the ashpit to the bearing 6) would require to be provided for the reception (and
removal) of the trunnion. Or on the face of the end pieces b¹² may be fixed plates
provided with square holes through which is passed a square rod or shaft arranged
to work in suitable bearings fixed within the ashpit in which case the shaft would,
on the outside of the ashpit, be armed with a lever or handle of any suitable size
and shape.
In some cases and when preferred in order to divide the ashes and prevent them
gravitating in a solid mass to the lower end of the screen at each oscillation, I
arrange what I term a dividing rake e formed as follows:
C
The end c of the main or horizontal portion C is carried by a bearing e¹ fixed to
the end piece while the opposite end c² is bent so as to hook into a loop or
recess formed for its reception either on the bearing or side of the ashpit. The
bearing c¹ and loop e³ are arranged so that the horizontal portion of the dividing
rake C is carried above the screen parallel with the axis of the trunnions.
It
From the horizontal portion C any desired number of prongs c (three are shown
in the drawings) may project downwards into the screen for dividing the ashes.
will readily be understood that by hooking the end of the dividing rake C, into the
loop the rake is held in a firm and stationary position during the oscillation of the
screen. Suitable openings (covered by lids or doors) may be provided in the sides
of the movable ashpit if desired for the removal of the dust ashes and other
substances. The ashes to be sifted are first placed in the screen B, the lid a is
then closed, afterwards the handle 60 is rocked to and fro until the dust and useless
substances has passed through the meshes of the wire worked bottom b into ashpit
below. After the dust has settled the lid a is raised and the screen containing the
cinders is removed from the ashpit as described.

page_text: It will be readily understood that the above described apparatus may be readily
adapted for use for many purposes besides sifting or screening cinders.. As for
instance it may be used for riddling sand lime and the like or when made on a small
scale for domestic purposes as a sifter or dredger.
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. In the sifting or screening of cinders and ashes the use of a screen such as B
mounted within a movable or fixed ashpit such as A capable of being oscillated by
the means substantially as herein set forth and illustrated.
2. In apparatus for the sifting or screening of cinders and ashes the combination
with a movable or fixed ashpit such as A, of a screen such as B (with or without
a dividing rake) mounted within the ashpit on fixed or detachable trunnions.
substantially as and for the purposes set forth.
3. In apparatus for sifting or screening cinders and ashes the combination of a
movable or fixed ashpit such as A and screen such as B with trunnions such as 6³ 6*
as and for the purposes set forth.
4. In apparatus for screening or sifting of cinders and ashes a trunnion such as b
prolonged bent and attached to an oscillating screen such as B as and for the
purposes set forth.
Dated the Sixth day of July 1891.
