IMPROVEMENTS IN THE MECHANISM OR APPARATUS FOR CRUSHING OR BREAKING-UP ORES, STONES, AND OTHER HARD SUBSTANCES
Year: 1861

page_text: LETTERS PATENT to William Smyth, Mining Engineer, and Matthew
Wasley, Mine Manager, both of Coed Mawr Pool Mine, in the County
of Carnarvon, for the Invention of "IMPROVEMENTS IN THE MECHANISM
OR APPARATUS FOR CRUSHING OR BREAKING-UP ORES, STONES, AND OTHER HARD
SUBSTANCES."
Sealed the 19th July 1861, and dated the 29th January 1861..
PROVISIONAL SPECIFICATION left by the said William Smyth and
Matthew Wasley at the Office of the Commissioners of Patents, with his
Petition, on the 29th January 1861.
SMYTH,
We, WILLIAM SыYтя, Mining Engineer, and MATTHEW WASLEY, Mine
Manager, both of Coed Mawr Pool Mine, in the County of Carnarvon, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MECHANISM OR APPARATUS FOR CRUSHING OR BREAKING-UP ORES, STONES, AND OTHER
HARD SUBSTANCES," to be as follows:-
This Invention consists in the use and adoption of a bed to receive the ores
or substances to be crushed or broken, which is made of cast iron (or other
suitable substance), with steel bars on the top or perforated plates of different
sizes, according as the nature of the stuff may require; and the stuff will
discharge under the bed as it is broken. Any form of bars or perforated

page_text: plates may be used for the breaking of ore, stuff, stone, or any other hard
substance; and we do not confine ourselves to the use of steel bars, as other
materials may be found to answer.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Smyth and Matthew Wasley in the Great Seal
Patent Office on the 26th July 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
SMYTH, Mining Engineer, and MATTHEW WASLEY, Mine Manager, both of
Coed Mawr Pool Mine, in the County of Carnarvon, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of January, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fourth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said William Smyth and Matthew Wasley, Her special licence that
we, the said William Smyth and Matthew Wasley, our executors, adminis-
trators, and assigns, or such others as we, the said William Smyth and
Matthew Wasley, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 " IMPROVE-
MENTS IN THE MECHANISM OR APPARATUS FOR CRUSHING OR BREAKING-UP ORES,
STONES, AND OTHER HARD SUBSTANCES," upon the condition (amongst others)
that we, the said William Smyth and Matthew Wasley, our executors or
administrators, by an instrument in writing under our, or their, or one of our
or their hands and seals, 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 William Smyth and Matthew Wasley,
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 thereof, that is to say :-
The nature of the said Invention was in and by the Provisional Specification

page_text: left and recorded on application for the said Letters Patent, declared to be the
same as it is now hereby declared to be, viz. :-
This Invention consists in the use and adoption of a bed or place to receive
the ores or substances to be crushed or broken, which is made of cast iron or
other suitable substance, with steel (or steeled). bars on the top, or perforated
plates of different sizes, according as the nature of the stuff may require, and
the stuff will discharge under the bed or bars as it is broken. Any form of
bars or perforated plates may be used for the breaking of ore, stuff, stone, or
any other hard substance; and we do not confine ourselves to steel bars, as
other materials may be found to answer. Or, in other words, instead of
having a bed or crushing floor of solid metal or other suitable substance, wo
form a strong grating or surface composed of bars and openings between them,
upon which bars or grating the ores, stones, or hard substances are pushed or
placed beneath stampers (which we prefer to make with a slit for the tappets
or tongues on the motive barrel or axis to take in, and thus lift the stamper
instead of having a lifter, tongue, or projection attached to the stamper, lifted
by the said first-named tappet or tongue, as in the old plan); and which
stampers or other crushing or breaking-up mechanisms are arranged to act
upon the said bed (in any manner known and practised by mechanicians), so
that the ores, stones, or other hard substances will, upon sufficient power
being applied thereto, be crushed or broken upon the bars or solid parts of the
grating or openwork, which are of steel, or are steeled at the edges as
thus (the black at the corners denoting steel), and the ore, stuff, or
stones, or hard substances are considerably reduced in size, and pressed by the
action of the stampers or crushing mechanism through the apertures between
the bars or open spaces of the grating to beneath the surfaces of the same,
where we prefer to receive same on an inclined surface for the crushed stuff
to fall upon, such surface being provided in a strong supporting framing for
the aforesaid bed, which surface will cause the crushed stuff to run down upon
a grating or sifter, so that the finely broken or crushed parts may drop through
and the large parts will roll forward beyond such finely crushed parts, causing
a separation, which large parts may be again crushed or broken upon another
bed, which has more numerous bars or solid parts and smaller openings
between them, so as to again reduce the ores, stones, or hard substances still
further, which crushing upon different beds may be repeated as often as may
be found requisite.

forth) as herein-before set forth and described.
In witness whereof, we, the said we, the said William Smyth and
Matthew Wasley, have hereunto set our hands and seals, this Twenty-
second day of July in the year of our Lord One thousand eight hundred
and sixty-one.
WILLIAM SMYTH.
