Year: 1873

page_text: LETTERS PATENT to John Manock, of the Firm of Manock Brothers,
of Birmingham, in the County of Warwick, Artificial Manure
Manufacturers, and Edmund Manock, of Heywood, in the County
of Lancaster, Mechanic, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR REDUCING AND SCREENING OR RIDDLING ARTIFICIAL MANURES
AND OTHER SUBSTANCES.
"
Scaled the 14th November 1873, and dated the 17th June 1873.
PROVISIONAL SPECIFICATION left by the said John Manock and
Edmund Manock at the Office of the Commissioners of Patents,
with their Petition, on the 17th June 1873.
We, JOHN MANOCK, of the Firm of Manock Brothers, of Birmingham,
in the County of Warwick, Artificial Manure Manufacturers, and
EDMUND MANOCK, of Heywood, in the County of Lancaster, Mechanic,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MACHINERY FOR REDUCING AND SCREENING OR RIDDLING ARTIFICIAL MANURES
AND OTHER SUBSTANCES," to be as follows:-
Our Invention relates to a combination and arrangement of mechanism
for reducing and riddling various substances, and consists of a cylindrical

page_text: sieve or riddle which is made to rotate on a shaft that carries bars armed
with pins or blades (set at an angle if required) that rotate with the shaft,
the points of the pins or blades nearly touching the inner surface of the
cylindrical riddle. The said shaft and cylindrical riddle are geared to
rotate in the same or opposite directions, but the said shaft is made to
rotate faster than the cylindrical riddle.
In some cases the inside of the riddle is armed with pins or blades
arranged so that the pins or blades carried by the said shaft will pass
between the pins or blades fixed to the cylindrical riddle.
The artificial manure or other substance to be operated upon is fed
through a pipe or hopper to one end of the cylindrical riddle, and is acted
upon by the pins or blades, and such substances as cannot be reduced
and passed through the cylindrical riddle are delivered at its other
end.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Manock and Edmund Manock in the Great
Seal Patent Office on the 16th December 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
MANOOK, of the Firm of Manock Brothers, of Birmingham, in the
County of Warwick, Artificial Manure Manufacturers, and EDMUND
MANOCK, of Heywood, in the County of Lancaster, Mechanic, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of June, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said John Manock and Edmund Manock,
Her special license that we, the said John Manock and Edmund Manock,
our executors, administrators, and assigns, or such others as we, the
said John Manock and Edmund Manock, our 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

page_text: United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY FOR
REDUCING AND SCREENING OR RIDDLING ARTIFICIAL MANURES AND OTHER
SUBSTANCES," upon the condition (amongst others) that we, the said
John Manock and Edmund Manock, by an instrument in writing under
our hands and seals, or under the hand and seal of one of us, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be 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.
NOW KNOW YE, that we, the said John Manock and Edmund
Manock, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement and the accom-
panying Drawings (that is to say):-
Our Invention relates to a combination and arrangement of mechanism
for reducing and riddling various substances, and consists of a cylindrical
sieve or riddle which is made to rotate on a shaft that carries bars armed
with pins or blades (set at an angle if required) that rotate with the shaft,
the points of the pins or blades nearly touching the inner surface of the
cylindrical riddle. The said shaft and cylindrical riddle are geared to
rotate in the same or opposite directions, but the said shaft is made to
rotate faster than the cylindrical riddle.
In some cases the inside of the riddle is armed with pins or blades
arranged so that the pins or blades carried by the said shaft will pass
between the pins or blades fixed to the cylindrical riddle.
The artificial manure or other substance to be operated upon is fed
through a pipe or hopper to one end of the cylindrical riddle, and is acted
upon by the pins or blades, and such substances as cannot be reduced
and passed through the cylindrical riddle may be delivered at its other
end or withdrawn by hand. Or a portion of the cylindrical part of the
riddle may be arranged on hinges as a door through which stones and
hard lumps or substances which cannot be easily broken up small
enough to pass through the meshes of the riddle may be allowed to drop

page_text: Fig. 1 is a horizontal section; Fig. 2 is a cross section; Fig. 3, a plan;
and Fig. 4, an end elevation of a machine according to our Invention.
A are two end frames connected by the cross bars A¹; a is the shaft
forming the axis of the cylindrical riddle 6 which is formed by two
pulleys b' that rotate freely upon the shaft a, which pulleys 6' carry the
two ends of the cylindrical riddle (6). Within the cylindrical riddle and
on the shaft a are fixed two pulleys c which carry cross bars c¹, in which
the pins are secured. The pulleys 6¹ for the riddle and those (c) for
the pins are formed with arms, so that the material to be operated
upon can pass between them to the interior of the riddle from the
hopper & secured to the end framing A. a are driving belt pulleys
which give motion to the shaft a, and there is a wheel e upon this
shaft which drives one (f) upon a stud that geers with one g¹ upon a
shaft g having bearings in both end frames A; which shaft has a
wheel secured upon it that gears with a plate wheel 62 which is
secured to one of the pulleys 6' that carry the riddle which is thus
rotated slowly in a contrary direction to that in which the pins c³ are
rotated by the shaft a; a* is a fly wheel on the shaft a; h is a cap to fit
the boss of the bearing to keep the dirt from it; d is a door in the
hopper hinged at d² to remove stones or pieces unbroken, and which will
not pass through the meshes of the riddle. The machine is covered by
a casing of sheet metal in which there is a door hinged at to
examine the riddle. The material which has been pulverized and
reduced fine enough to pass through the riddle will fall below it, and to
make sufficient room and give space to remove the pulverised material,
the machine is fixed upon two walls of sufficient height so as to form
a space under the cylindrical riddle. Or the machine may be placed on
a floor in which there is a hole, through which the material can fall into
a room below. The riddle may be mounted so as to be supported
entirely at one end, and rotated by a hollow shaft working in two
bearings in a headstock, and the bars carrying the pins may also be
carried and rotated upon the end of a solid shaft working in and through
the hollow shaft, which arrangement would leave one end of the cylin-
drical riddle entirely opened for the material to be fed into it by a shovel
or by the hopper.
We have now particularly described the nature of our Invention, and
the manner of carrying the same into effect, and claim as our Invention
the combination and arrangement of a cylindrical riddle and arms having

page_text: pins or blades made to rotate within the riddle, substantially as herein-
before described and illustrated by the accompanying Drawings.
In witness whereof, we, the said John Manock and Edmund
Manock, have hereunto set our hands and seals, this Twelfth
day of December, in the year of our Lord One thousand eight
hundred and seventy-three.
