Year: 1873

page_text: LETTERS PATENT to John Prior Ward, of 4, Albert Street, South
Hackney, in the County of Middlesex, Consulting Accountant, for
the Invention of "IMPROVEMENTS IN APPARATUS FOR SIFTING CINDERS
AND OTHER SUBSTANCES.”
Sealed the 19th August 1878, and dated the 22nd February 1878..
PROVISIONAL SPECIFICATION left by the said John Prior Ward at
the Office of the Commissioners of Patents, with his Petition, on
the 22nd February 1873.
I, JOHN PRIOR WARD, of 4, Albert Street, South Hackney, in the
County of Middlesex, Consulting Accountant, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR SIFTING
CINDERS AND OTHER SUBSTANCES," to be as follows:—
This Invention relates to improvements in apparatus for sifting cinders
and other substances with the least possible labour and wasto.
A simple form of apparatus constructed according to this Invention
and designed for sifting cinders in the apartment in which the fucl has
been burning or elsewhere is as follows:-I construct a receptacle of

page_text: convenient size, and by preference of rectangular form of sheet iron or
other suitable material, and divide the same into two compartments by
a partition placed in an inclined direction, and reaching from the bottom
of the receptacle to within a few inches (more or less) of the top. Thus
of these two compartments one will be larger at the top than the other,
the larger one being for receiving the ashes, and the smaller the cinders
as herein-after moro fully described. On a level with the top of the said
partition a ledge is formed around the interior of the receptacle, on
which ledge is made to rest a sifter made up by a blank plate, and a sieve
of wire or other suitable material, or a grating of cast or wrought iron or
other substance. This sifter is constructed with sides so that it may
hold as much cinder and ash as it is desired to operate on at one timo,
and is so placed on the ledge that the sieve portion of it will be over tho
ash compartment, and the blank portion cover the cinder compartment;
the said blank portion being just sufficiently wide to cover the top of the
cinder compartment when the sifter in receiving the necessary vibratory
motion is drawn over it; thus a certain amount of mixed cinders and
ashes being put into the said sifter and a vibratory motion being imparted
thereto the ashes will be caused to pass through into the compartment
intended to receive them, whilst the cinders remaining may be passed
over the blank plate into the compartment intended for them. The outer
casing may be covered in by a lid made either to open on hinges or to
slido on in grooves, and the necessary vibratory motion may be imparted
to the sifter whilst the lid is closed to confine the dust by means of a
handle attached to tho sifter, and made to pass through the casing.
Three apertures covered by doors are also constructed in the side of
the apparatus, communicating with the cinder compartment, and the
other two with that for the ashes, one near the top, and the other near
the bottom; that one near the top being for the introduction of any
clinker or such waste substance as will not pass through the sieve, and §
the lower one for the removal of the ashes; whilst that one communi-
cating with the cinder compartment is for the removal of the cinders
which may thus if desired bo at once returned to the fire from which
they have come. This apparatus may be made ornamental so as to
adapt it for use, even in the drawing room.

When desired the apparatus may be fitted with a succession of
graduated sioves, one below the other, and cach in connection with
separate compartments, so that the substanco acted upon may be divided
into sovoral different degress of fineness.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Prior Ward in the Great Seal Patent Offico
on the 22nd August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PRIOR WARD, of 4, Albert Street, South Hacknoy, in the County of
Middlesex, Consulting Accountant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of February, in the
year of our Lord One thousand eight hundred and seventy-three, in tho
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Prior Ward, Her special license
that I, the said John Prior Ward, my executors, administrators, and
assigns, or such others as I, the said John Prior Ward, my excoutors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN APPARATUS FOR SIFTING CINDERS AND OTHER SUBSTANCES," upon the condition
(amongst others) that I, the said John Prior Ward, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and scals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to bo
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the
said Letters Patent.

page_text: 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 thereof (that is to say) :-
This Invention relates to improvements in apparatus for sifting cinders
and other substances with the least possible labour and waste.
And in order that my said Invention may be clearly understood and
readily carried into effect, I will proceed to describe the same with the
aid of the accompanying Drawings, reference being had to the letters
and figures marked thereon, and in which Figure 1 is a front view of an
apparatus constructed according to my Invention, and designed for sifting
cinders in the apartment in which the coal has been burned or elsewhere;
Figure 2 is a vertical section thereof; Figuro 3 is an end view; Figures 4
and 5 plan views with the top removed, and showing the sifter in
different positions; and Figure 6, a detached plan view of the sifter.
The same lotter wherever it occurs indicates like or corresponding parts.
I construct a receptaclo A. of convenient size, and by preference of
rectangular form, of sheet iron or other suitable material, and divide tho
namo into two compartments B and O, by a partition D fixed in an
inclined direction as shewn, and extending from the bottom of the
receptacle to within a short distance of the top. One of these two com-
partments (B) is constructed larger at the top than the other, the larger
one (B) being for receiving the ashes, and the smaller (0) for the cinders
as herein-after more fully described. At the top of the said partition a
ledge E is formed, around the interior of the receptacle on which ledge is
made to rest a sifter F made up of sloping blank plate F", and a sievo I*
of wire or other suitable material, or a grating of cast or wrought iron or
other substance. This sifter is constructed with uprising sides so that
it may hold a moderato amount of cinder and ash to be operated on at
one time, and is so placed on the ledge that the sieve portion F³ will bo
over the ash compartment, and tho blank portion F' over the cinder
compartment; the said blank portion being just sufficiently wide to
cover the top of the cinder compartment when the sifter in receiving the
necessary vibratory or shaking motion is drawn over it, as shown in
Figure 4. The apparatus being thus constructed a certain amount of
mixed cinders and ashes such as are taken up from under an ordinary

page_text: house fire-grato aro put into the said sifter. A vibratory motion is then
imparted thereto by means of the handle G which projects through tho
sido of the receptacle, and the ashes aro thus caused to pass through
into tlio compartment intended to receive them, whilst the cindors are at
the same time jerked over tho blank plate of the sifter into the com-
partment intended for them. During the process of sifting the lid H is
closed to confino tho. dust. This lid may be made cither to open on
hinges or to slide in grooves. Throe apertures covered doors I, I', I',
are also constructed in one side of the apparatus, one (I) communicating'
with the cinder compartment, and the other two I and I') with that
for the ashes; the upper one being for the introduction of any clinker or
such wasto substance as will not pass through the sieve, and the lower
one for the removal of the ashes. That one communicating with the
cinder compartment is for the removal of the cinders which may thus if
desired be at once returned to the fire from which they have come. Or
these doors may be dispensed with, and two sliding doors J, one com-
municating with cach compartment may be substituted. This apparatus
may be made ornamental so as to adapt it for uso even in the drawing

page_text: as herein-before set forth and described, and illustrated in the accom-
panying Drawings.
In witness whereof, I, the said John Prior Ward, have hereunto
set my hand and seal, this Twenty-second day of August, in the
year of our Lord One thousand eight hundred and seventy- 5
three.
