IMPROVEMENTS IN MACHINERY TO BE USED WHEN CASTING METALS
Year: 1860

page_text: LETTERS PATENT to William Barrett, of Norton, near Stockton-on-Tees,
for the Invention of "IMPROVEMENTS IN MACHINERY TO BE USED WHEN
CASTING METALS."
Sealed the 18th January 1861, and dated the 19th July 1860.
PROVISIONAL SPECIFICATION left by the said William Barrett at the
Office of the Commissioners of Patents, with his Petition, on the
19th July 1860.
I, WILLIAM BARRETT, of Norton, near Stockton-on-Tees, do hereby declare
the nature of the Invention for "IMPROVEMENTS IN MACHINERY TO BE USED
WHEN CASTING METALS," to be as follows:-
This Invention has for its object improvements in apparatus to be used:
when casting metals, and is applicable when several castings of the same kind
are required. For this purpose, when making moulds either by machinery or
by hand labour, the moulds as they are formed are deposited, either by hand
or by mechanical means, upon a horizontal circular table, rotating on a vertical
axis. A step-by-step motion is given to this table, and a mould is placed on
the table for each of its movements. When the table has made a partial
revolution the moulds arrive at a spot where they are supplied with metal,

page_text: either from a fixed or portable ladle, whilst the table remains stationary. By
the continued rotation of the table the moulds are brought to a point, where
they are removed from the table, and the boxes containing the moulds are
emptied, the table being of sufficient diameter to allow of the metal setting
between the time that the moulds are filled and the time when, by the rotation
of the table, they arrive at the point where they are removed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Barrett, in the Great Seal Patent Office on the
19th January 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BARRETT, of Norton, near Stockton-on-Tees, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of July, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Barrett, Her special licence that I, the said William
Barrett, my executors, administrators, and assigns, or such others as I,
the said William Barrett, 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 "In-
PROVEMENTS IN MACHINERY TO BE USED WHEN CASTING METALS," upon the con-
dition (amongst others) that I, the said William Barrett, 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 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 William Barrett, 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 thereof, that is to say:-
This Invention has for its object improvements in apparatus to be used when

page_text: casting metals, and is applicable when several castings of the same kind are
required. For this purpose, when making moulds either by machinery or by
hand labour, the moulds as they are formed are deposited either by hand or
by mechanical means upon a horizontal circular table rotating on a vertical
axis. A step-by-step motion is given to this table, and a mould is placed on
the table for each of its movements. When the table has made a partial
revolution, the moulds arrive at a spot where they are supplied with metal,
either from a fixed or portable ladle, whilst the table remains stationary. By
the continued rotation of the table the moulds are brought to a point where
they are removed from the table and the boxes containing the moulds are
emptied, the table being of sufficient diameter to allow of the metal setting
between the time that the moulds are filled and the time when by the rotation
of the table they arrive at the point where they are removed.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a plan of so much of machinery, arranged according to my
Invention, as will enable me to describe the same; Figure 2 shows a vertical
section thereof.
A is a circular table mounted on a vertical axis A', which turns in suitable
bearings at its lower and upper ends. The table is to be caused to rotate at
intervals on its axis a distance equal to that between the centres of the mould
boxes for the time being in use on the table, which may be done by the
workman who has charge of the table, so as at all times to bring the mould
which is about to receive metal into a correct position under the lip or spout
of the ladle, or, where the mould boxes are alike, and the distance between
them is uniform, the rotation at intervals may be done by machinery, which
a mechanical engineer will readily apply. The mould is made on a table
at B, and is then slid along the rails on to the table A, and the upper part
of the mould is placed on the other part or parts of the mould at C. The
moulds, as they arrive in succession opposite the ladle D, are filled with
metal, and they pass on to the point E, where the boxes are moved off
the table A on to rails or plates to be emptied, and then the boxes are
brought again to the table B, where they are again used. F is a heap of
sand.
+
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I make no claim to the

page_text: mechanical parts separately, but what I claim is the combined arrangement
herein described.
In witness whereof, I, the said William Barrett, have hereunto set my
hand and seal, this Eighteenth day of January, in the year of our
Lord One thousand eight hundred and sixty-one.
Signed, sealed, and delivered in the
presence of
WILLIAM WARNER NORTON.
