page_text: LETTERS PATENT to John Macdonald Moody, of Gosport, in the
County of Hants, Captain in the Royal Marine Light Infantry, for
the Invention of "IMPROVEMENTS IN CINDER SIFTERS, WHICH IMPROVE-
MENTS ARE ALSO APPLICABLE FOR SIFTING OR SEPARATING OTHER SUBSTANCES."
-A communication from abroad by John Sutton, of Islip, in the
State of New York, United States of America.
Sealed the 1st February 1876, and dated the 4th August 1875.
PROVISIONAL SPECIFICATION left by the said John Macdonald
Moody at the Office of the Commissioners of Patents, with his
Petition, on the 4th August 1875.
I, JOHN MACDONALD MOODY, of Gosport, in the County of Hants,
Captain in the Royal Marine Light Infantry, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN CINDER SIFTERS,
WHICH IMPROVEMENTS ARE ALSO APPLICABLE FOR SIFTING OR SEPARATING OTHER
SUBSTANCES," to be as follows:-

page_text: particularly for sifting coal ashes and separating the cinders from the
fine ashes and dust, but which may be used for other analogous
purposes.
The Invention consists in a novel construction and combination of
parts whereby the cinders are separated from the fine dust and ashes by
centrifugal force and deposited in an outer vessel or receptacle, and the
ashes are deposited in a removable inner vessel, both operations being
performed simultaneously.
In carrying out these improvements a cylindrical, square, or other
suitably shaped vessel of metal, wood, or other suitable material is used.
The vessel has a lid or main cover, which may be removable or may
be hinged to the vessel. In the center of the lid is an opening, in
which rests a conical hopper, which may be formed with a rim or flange
around its upper edge to support it in the opening. Below the hopper
is a sieve, which is attached to the hopper by means of rods or bars
extending from the edge of the sieve to the sides of the hopper. The
upper ends of these rods or bars may be turned outward and bear
against the under side of the lid around the edge of the opening for the
purpose of keeping the hopper in place. The sieve may be either flat,
concave, or convex, and is formed without sides or rims extending
upward, but with an ash-deflecting rim extending downward from the
under side and tapering inward. The hopper and sieve receive a rotary
motion, which may be either continuous or reciprocating by means of a
handle attached to the hopper, which handle may be a crank or a knob.
The cover of the hopper has one portion removable or arranged to swing
or slide open to allow the ashes to be placed in the hopper and then be
closed to prevent the escape of dust.
Immediately under the sieve is an ash receptacle, which is placed
concentrically in the outer case, and fits into a cylindrical holder, and
an annular space is thus formed between the cylindrical holder and the
outer case, which annular space serves as a chamber for the reception of
the cinders after they are sifted. Near the bottom of the outer case
and on one side of it is a door surrounded by an arched passage, through
which the cinders may be removed from the vessel.
The ashes to be sifted are placed in the hopper, and the cover of the
hopper is closed to prevent the dust from arising therefrom. The sieve

page_text: is then rotated or oscillated as before described, and the cinders arc
separated from the fine ashes and dust and thrown centrifugally from
the edge of the screen, falling through the annular space into the lower
part of the outer casing, from which they may be removed through the
door, the arch serving to prevent the cinders from falling out when the
door is opened. The fine ashes and dust separated from the cinders pass
through the sieve and fall into the ash receptacle, which may be readily
removed when necessary.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Macdonald Moody in the Great Seal Patent
Office on the 4th February 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JoпN
MACDONALD MOODY, of Gosport, in the County of Hants, Captain in
the Royal Marine Light Infantry, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of August, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Macdonald Moody, Her special
licence that I, the said John Macdonald Moody, my executors, adminis-
trators, and assigns, or such others as I, the said John Macdonald Moody,
my executors, 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 Cinder SifteRS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE
FOR SIFTING OR SEPARATING OTHER SUBSTANCES," being a communication to
me from abroad by John Sutton, of Islip, in the State of New York,
United States of America, upon the condition (amongst others) that I,
the said John Macdonald Moody, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of

page_text: the said Invention, and in what manner the same was to be per-
formed, 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.
NOW KNOW YE, that I, the said John Macdonald Moody, 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, reference being had to the Drawing
hereunto annexed and to the letters and figures marked thereon (that
is to say):-
This Invention relates to an apparatus which is designed more
particularly for sifting coal ashes and separating the cinders from the
fine ashes and dust, but which may be used for analogous purposes.
The Invention consists in a novel construction and combination of
parts whereby cinders are separated from the fine dust and ashes by
centrifugal force and deposited in an outer vessel or receptacle, and the
ashes are deposited in a removable inner vessel, both operations being
performed simultaneously.
In the accompanying Drawing Fig. 1 is a central vertical section of a
sifter constructed according to this Invention, and Fig. 2 is a top view
of the same with the cover thrown back.
A represents a vessel, which may be of cylindrical, square, or other
suitable shape, and of metal, wood, or other suitable material; B is the
lid or main cover of the vessel, which lid may be removable or may be
hinged to the vessel as shown. In the centre of the lid is an opening,
in which rests a conical hopper C, which may be formed with a rim or
flange c around its upper edge to support it in the opening. Below the
hopper is a screen D, which is by preference attached to the hopper by
means of rods or bars d extending from the edge of the screen to the
sides of the hopper. The upper ends of these rods or bars d may be
turned outward and bear against the under side of the lid B around the
edge of the opening for the purpose of keeping the hopper in place.
The screen D may be either flat, concave, or convex, and is formed
without sides or rims extending upward, but with an ash deflecting
rim fextending downward from the under side and tapering inward.
The hopper and screen receive a rotary motion either continuous or

page_text: reciprocating. The means provided for imparting this rotary motion
consists of a handle E attached to the hopper C, which handle may be a
crank or a knob, or a handle attached to the screen, as at E*, may be
used, a slot being made in the outer case to permit of its receiving a
reciprocating movement.. The cover G of the hopper has one portion g
removable, or arranged to swing or slide open to allow the ashes to
be placed in the hopper and then be closed to prevent the escape of
dust.
Immediately under the screen D is an ash receptacle, consisting of a
vessel H, provided with a handle or cross bar / for handling or lifting it.
This vessel H is placed concentrically in the vessel A, and is held in
place by means of a circular holder J which rests upon a grating or
upon bars i arranged a short distance above the bottom of the vessel A.
K is an annular space formed between the outer side of the circular
holder J and inner side of the vessel A, into which the cinders fall as
they are sifted out. The vessel H and holder J are preferably tapering
in form in order to facilitate the withdrawal of the vessel H and to
prevent the cinders from clogging when accumulating in the annular.
space K. Near the bottom of the vessel A, and on one side of it, is a
door L surrounded by an arched passage M, through which the cinders
may be removed from the vessel.
The ashes to be sifted are placed in the hopper C, and the cover of
the hopper is closed to prevent the dust from rising therefrom. The
screen is then rotated, by which means the cinders are separated from
the fine ashes and dust and thrown centrifugally from the edge of the
screen D, falling through the annular space K into the lower part N of
the vessel A, from which they may be removed through the door L, the
arch M serving to prevent the cinders from falling out when the door is
opened. The fine ashes and dust separated from the cinders pass through
the screen and fall into the ash receptacle H, which may be readily
removed when necessary.
Having now described the nature of the said Invention for " Improve-
ments in Cinder Sifters, which Improvements are also applicable for
Sifting or Separating other Substances," and having explained the
manner of carrying the same into effect, as communicated to me by my
foreign correspondent, I wish it to be understood that under the above
in part recited Letters Patent I claim, the combined arrangement of

page_text: hopper, sideless rotating or reciprocating screen, and inner and outer
receptacles or vessels having a space between them, substantially as and
for the purpose described.
