IMPROVEMENTS IN CRUSHING AND PULVERIZING QUARTZ AND OTHER SUBSTANCES
Year: 1853

page_text: LETTERS PATENT to Moses Poole, of Avenue Road, Regent's
Park, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN CRUSHING AND PULVERIZING QUARTZ AND
OTHER SUBSTANCES."-A communication from T. Briggs Smith,
of Taunton Massachusetts United States of America
Sealed the 3rd November 1853, and dated the 23rd August 1853.
PROVISIONAL SPECIFICATION left by the said Moses Poole
at the Office of the Commissioners of Patents, with his
Petition, on the 23rd August 1853.
I, MOSES POOLE, of Avenue Road, Regent's Park, in the Provis
Specifi
County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN CRUSHING AND PULVERIZING
QUARTZ AND OTHER SUBSTANCES" to be as follows:-
The nature of my Invention consists in the forming of a corru-
gated surface in the bottom of a circular conical trough, with
corrugated or toothed rollers working upon the corrugated surface
in the trough, thereby making the two corrugated surfaces come
in contact with each other, and thus produce a better crushing
action than has heretofore been obtained.

Patent, filed by the said Moses Poole in the Great Seal
Patent Office on the 11th February 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME,
I, MOSES POOLE, of Avenue Road, Regent's Park, in the County
of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by
Her Letters Patent, bearing date the Twenty-third day of August,
in the year of our Lord One thousand eight hundred and fifty-
three, in the seventeenth year of Her reign, did, for Herself, Her
heirs and successors, give and grant unto me, the said Moses
Poole, Her special licence that I, the said Moses Poole, my execu-
tors, administrators, and assigns, or such others as I, the said
Moses Poole, 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 CRUSHING AND
PULVERIZING QUARTZ AND OTHER SUBSTANCES," a communication
from T. Briggs Smith, of Taunton, Massachusets, United States of
America, upon the condition (amongst others) that I, the said
Moses l'oole, by an instrument in writing under my hand and seal,
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 I, the said Moses Poole, do hereby de-
clare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof (that is to say):
The nature of my Invention consists in the forming of a corru-
gated surface in the bottom of a circular conical trough, with
corrugated or toothed rollers working upon the corrugated surface

page_text: in contact with each other, and thus produce a better crushing
action than has heretofore been obtained.
DESCRIPTION OF THE DRAWING.
The same letters refer to the same parts of Drawing in plan and
sectional elevation.
A, is a circular conical cast iron trough for the purpose of con-
taining the material to be operated upon. On this trough are cast
projections, and a cross or arms to support the upright shaft, and
a frame herein-after described.
B, is a corrugated or toothed bottom, cast of very hard iron to
prevent rapid w ar, which may be made in segments or one piece,
as may be thought proper.
C, C, are five corrugated bevelled rollers, the rims and corruga-
tions of which are cast of very hard iron to prevent rapid wear,
and put together as shewn in the Drawing, these corrugations
corresponding with the corrugated surface B, and are made to
revolve upon the corrugated or toothed bottom which is placed
in the circular trough A.
D, the driving bevel wheel fixed to the upright shaft for the
purpose of communicating motion to the corrugated or toothed
rollers C, C.
E, is an upright shaft placed in the centre of the circular
trough A, supported by the frame at the top and a step at the
bottom.
F, F, are five axles attached loosely to the bevilled rollers C, C,
each terminating in a pin joint fixed in the hub or boss of the
driving wheel D, the object of which joints is to allow the rollers
to rise or fall in proportion to the resistance that may be presented
by the substance to be operated upon; the outer ends of these
axles F, F, project beyond the outer surface of the roller, which
projection moves between lugs formed on the inner part of the
driving bevel wheel D, these lugs being made of sufficient depth
to allow the rollers to rise or fall, as may be required.
G, is a cast iron cap secured to the top of the hub or boss on

page_text: the driving bevel wheel D, for the purpose of holding the pin
joints of the axles F, F, in their proper places; by removing this
cap one or more of the rollers and axles may be removed,
repaired, and replaced with facility.
H, is a strong cast iron frame for the purpose of supporting
the upright shaft E, and the horizontal shaft J, which frame is
secured to the projections cast on the bottom of the circular
trough A.
I, is a driving bevel pinion working into the bevel wheel D,
which pinion communicates motion to the whole machine.
J, is a horizontal shaft, upon which is secured the bevel
pinion I, and the driving pulley or wheel, as may be found most
practicable under the circumstances in which the machine may
be placed.
Having thus described the nature of the said Invention, and the
manner of performing the same, I would have it understood that
what I claim as my Invention, and for which I desire Letters
Patent granted, is, the construction of a machine with corrugated
or toothed surfaces working into each other, whereby I obtain a
vertical crushing motion, and also an amount of pulverising
surface not obtained by any other machine heretofore named.
I do not claim the circular motion, but the peculiar form of
surface, or any other substantially the same in its effect.
In witness whereof, I, the said Moses Poole, have hereunto
set
my hand and seal, this Twenty-seventh day of January,
in the year of our Lord One thousand eight hundred and
Witness,
B. GOBEY,
12, Cursitor Street,
Chancery Lane.
