Improvements in or relating to Means or Apparatus for Sifting,
Grading, or Separating Cinders, Chemicals, and the like, also
Straining Liquids and Paint.
I, JOHN SQUIRE, of 6 West View, 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, grading, or separating
the dust or finer materials from cinders, chemicals, or the like, also for straining
liquids, and paint; and its object is to provide simple, ready, and effective means
for grading or straining the finer or refuse portions from the larger or that which
is more valuable.
According to this invention I provide a suitably shaped air or dust tight or
other receptacle provided with a hinged or removable lid, or with a top, or with a
tray, and with one or more delivery spouts or outlets, and one or more openings or
apertures which may be closed, if desired, by doors or slides. Within the receptacle
may be provided, if desired, one or more division boards or plates of any suitable
material and made to extend a suitable distance from the bottom of the receptacle
in an upward direction to form two or more compartments. A box or other
receptacle capable of being drawn in and out may be passed through an aperture
into each compartment, or if desired the boxes or other receptacles and partition
may be dispensed with. At a suitable distance from the bottom of the receptacle
is mounted a semi-circular or other shaped basket or sieve or strainer, hereafter
termed a sieve, for the reception of the material or its equivalent to be sifted,
graded, separated, or strained. This sieve is suitably perforated and mounted at
each end by a trunnion in suitable slotted bearings in the receptacle so as to be
readily removed therefrom. A convenient form of device for retaining each of
the trunnions or their equivalents in their bearings consists of a disc fixed to the
side of the receptacle so as to be capable of rotating. In the disc is cut a slot
partially straight and partly curved. The trunnions are locked in position by the
curved portion of the said slots. Suitable handles and stops are provided for
rotating the discs, and for preventing them being rotated too far. One or both of
the trunnions is or are prolonged to receive a handle, wheel, pulley or its equivalent
by which the sieve may be oscillated by hand or power.
Within the rocking
sieve is placed or hung one or more suitable agitators. These agitators may be
either in the form of a rake, bar, or a brush, or a strip of india rubber or gutta
percha or all or any of them combined, or it or their equivalents. Stops are also
provided for controlling the arc of oscillation of the sieve. At a suitable distance
below the rocking sieve is provided and fixed a hopper having a large opening at
its lowest portion. Below the hopper and between the bottom of the receptacle
and top of the division board or plate, when such is used, is a direction board or
plate of any suitable material, divided if required into portions, and, mounted upon
a shaft or pivot, or its equivalent, so as to be capable of oscillating or tilting the
board or boards for directing the material falling through the perforations of the
rocking sieve into cue or both of the boxes, or into one or more of the delivery
spouts, and from thence into bags or receptacles for conveyance away. One or

page_text: more suitable handles, or it or their equivalents, is or are provided on the direction
board pivot or shaft, or attached to the board or its portions direct, for turning it
or them.
When desired a second oscillating sieve or strainer, or
a hinged door
armed with a suitable catch may be provided at the end of each delivery spout for
further sieving, grading, separating, or straining purposes, or for regulating the
exit of the material from such spout or hopper. In some cases both the tilting
boards, division plate, and boxes may be dispensed with, and a drawer, or box, or
other receptacle, or slide may be arranged immediately under the base of the
hopper.
also in some cases provide suitable bearings on the top of an open fixed, or
removable receptacle arranged at the side of the closed sifting, grading, separating
or straining apparatus, or on suitable supports which may also be arranged at the
side of the closed apparatus, or elsewhere, for supporting the rocking sieve,
whenever it is removed from the closed apparatus and for facilitating its
emptying.

Improvements in or relating to Means or Apparatus for Sifting,
Grading, or Separating Cinders, Chemicals, and the like, also
Straining Liquids and Paint.
I, JOHN SQUIRE, of 6 West View, 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, grading, or separating
the dust or finer materials from cinders, chemicals, or the like, also for straining
liquids and paint; and its object is to provide simple, ready, and effective means
for grading or straining the finer or refuse portions from the larger or that which
is more valuable, as well as for mixing and grading two or more chemical substances
together.
In the drawings hereunto annexed :-
Fig. 1 is an end elevation.
Fig. 2 a longitudinal section and Fig. 3 a transverse section of a portable ciuder
sifter constructed according to this invention.
Figs. 4 and 5 are respectively longitudinal and transverse sections of a fixed
sifting or grading apparatus provided with a tilting direction board and two
drawers.
Figs. 6 and 7 are respectively a longitudinal and transverse section of a fixed
sifting or grading apparatus provided with a tilting direction board, a delivery
outlet and an aperture closed with a door.
Fig. 8 is a transverse section of a fixed sifting or grading apparatus provided
with a drawer or box interposed between the sieve and the bottom of the
apparatus.
Fig. 9 is a transverse section of a fixed sifting or grading apparatus without a
cover.
In the drawings like parts are marked with similar leiters of reference.
A is a suitably shaped air or dust tight or other receptacle which may be made
in any couvenient shape and of any suitable material such as for instance metal,
wood, or the like.

page_text: In the drawing I have shown the receptacle made in various shapes as for
nstance at Figs. 4 to 8 it is provided with a hinged cover B but at Fig. 9 an
xample is given in which the lid or top is dispensed with and at Figs. 1 to 3
have shown the portable apparatus provided with a removable lid C capable of
being used as a tray for receiving brushes and other articles such as are used by
lomestic servants for stove cleaning and like purposes.
The receptacle A may also be provided with one or more delivery spouts or
outlets D armed with a hinged sliding or other door d such as is shown at Figs. 6
and 7; or within the receptacle may be provided and fixed if desired one or more
partitions or division boards or plates G (see Figs. 4 and 5) of any suitable
material and made to extend from the bottom of the receptacle A in an upward
direction so as to form two or more compartments. Into the compartments so
forined a box H may be passed into or drawn out through an aperture E or the
partition G may if desired be dispensed with altogether.
Although at Figs. 4 and 5 I have shown the boxes H as being inserted in the
transverse position yet I would have it understood the apertures E may be formed
in one of the ends instead of the sides as shewn, and the boxes H inserted longi-
tudinally. At Figs. 1, 2 and 9 1 have shown the aperture E formed in the side of
the receptacle and closed by a sliding door F1 but at Figs. 6, and 7, and 8 the
aperture E is shown closed by a door F (battened or otherwise). It will readily
be understood if desired the aperture E in these cases may be placed in any other
convenient position in the lower part of the receptacle.
At a suitable distance from the bottom of the receptacle A is mounted so as to
oscillate freely, a semicircular or other shaped basket, or sieve, or strainer, here-
after termed a sieve 1, for the reception of the material or its equivalent to be
sifted, graded, separated or strained.
The sieve is suitably perforated, that is for example, its semicircular
perimeter may if desired be formed of perforated zinc or woven wire webbing of
any suitable and convenient mesh. The sieve is mounted at each end by a
trunnion J in suitable slotted bearings formed in or fixed to the receptacle so that
the sieve may be readily removed therefrom. A convenient form of bearing may
be formed as follows; the sides or ends of the receptacle A may be slotted as at a
and on the outside of the receptacle is mounted a plate K (circular or otherwise)
formed as shewn at Fig. 1. In the plate K is cut a groove K' which partly
radiates to the centre of the plate and is partly circumferential, that is to say when
the radiating part of the groove is turned or rotated into a vertical position the
trunnions J and sieve I may be readily removed therefrom or placed therein in
the receptacle A. But when the plate is removed in the direction of arrow and
into the position shown at Fig. 1, the trunnions will be locked by the circum-
ferential portion of the groove in a position to prevent them being removed from
the slots until the plate is again rotated. A stop or pin K2 is fixed in the sides or

ends of the receptacle to prevent the plate being rotated too far.
the pin K is shown to work in a recess K³ formed in the perimeter of the plate,
In either case the ends
but if desired the pin may be arranged to work in a slot.
of the recess or slot would form the necessary stops. A handle K is provided for
rotating the plate K.
One or both of the trunnions J as shown respectively at Figs. 6 and 3 is or are
prolonged to form or receive a handle J' or when it is desired to oscillate the
sieve by power derived from any suitable source, a wheel or pulley may be
mounted and fixed on one of the trunnions which is prolonged to receive it.
Within the oscillating or rocking sieve 1 is placed or hung one or more suitable
agitators L. These agitators L may be either in any convenient form such as a
rake, as at Fig. 4, plain or recessed bar, as at Fig. 6, or a brush, or a strip of
india-rubber or gutta percha or all or any of them combined, or it or their
equivalents.
But it is arranged that the agitator L in all cases shall be stationary whilst the
sieve I is oscillating.

page_text: At Fig. 6 one end of the agitator L works in centre bearings formed in the
trunnion J (screwed to the side) and provided at its opposite end with a cross
piece to form a T which passes into a vertical slot or groove formed in or fixed to
the side of the receptacle.
Stops may also be provided for controlling the are of oscillation of the sieve.
But at Figs. 1 to 3 the stops may be dispensed with and the handle bent so that
they will come in contact with the top of the tray C instead.
At a suitable distance below the rocking sieve is provided and fixed a hopper M
baving a large opening m at its lowest portion. Below the hopper and between the
bottom of the receptacle and top of the division board is a plate N of any suitable
material, divided if required into two or more portions, and mounted upon a shaft
or pivot O. or its equivalent, so as to be capable of oscillating or tilting the board
or boards N for directing the material falling through the perforations of the
rocking sieve into one or both of the boxes H, or into one or more of the delivery
spouts D (and from thence into bags or receptacles for conveyance away) or into
the bottom of the receptacle itself. One or more suitable handles P or it or their
equivalents, is or are provided on the direction board pivot or shaft O, or attached
to the board or its portions direct, for turning it or them.
When desired a second oscillating sieve similar to I may be employed in place of the
hinged door (which is if desired armed with a suitable catch) at the end of each
delivery spont D for further sieving, grading, separating, or straining purposes, or
for regulating the exit of the material from such spout or hopper.
In some cases both the tilting boards, division plate, and boxes may be dispensed
with, and a drawer, or box Q (Fig. 8) or other receptacle or slide may be arranged
immediately under the base of the hopper.
I also in some cases provide suitable bearings on the top of an open fixed, or
removable receptacle arranged at the side of the closed sifting, grading, separating
or straining apparatus, or on suitable supports which may also be arranged at the
side of the closed apparatus, or elsewhere, for supporting the rocking sieve,
whenever it is removed from the closed apparatus and for facilitating its
emptying.
At Fig. 9 the sieve I is provided with a hinged lid R arranged so that when the
sieve is oscillating the lid may be kept closed by any convenient catch R'. But
when it is desired to empty the contents of the sieve into say one of the con-
partments of the receptacle A, the lid may be opened by its projecting end R'
coming in contact with the fixed top S which permits the sieve to continue its
oscillating whilst retaining the lid in an open position.
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 apparatus for sifting, grading, separating or straining cinders, chemicals,
liquids, and paint, substantially such as herein described and illustrated consisting
of a receptacle with or without a hinged or other lid and having a hopper and a
tilting direction board or boards arranged therein, in combination with an
oscillating sieve mounted above the said hopper and having a stationary agitator
arranged within it as and for the purposes herein set forth.
2. In sieving, separating and mixing apparatus substantially as herein described
and illustrated the combination with an oscillating sieve having a stationary
